    Notizen: Abstract Facility-specific information on pollution was obtained for 36 coke plants and 46 oil refineries in the United States and matched with information on populations surrounding these 82 facilities. These data were analyzed to determine whether environmental inequities were present, whether they were more economic or racial in nature, and whether the racial composition of nearby communities has changed significantly since plants began operations. The Census tracts near coke plants have a disproportionate share of poor and nonwhite residents. Multivariate analyses suggest that existing inequities are primarily economic in nature. The findings for oil refineries are not strongly supportive of the environmental inequity hypothesis. Rank ordering of facilities by race, poverty, and pollution produces limited (although not consistent) evidence that the more risky facilities tend to be operating in communities with above-median proportions of nonwhite residents (near coke plants) and Hispanic residents (near oil refineries). Over time, the racial makeup of many communities near facilities has changed significantly, particularly in the case of coke plants sited in the early 1900s. Further risk-oriented studies of multiple manufacturing facilities in various industrial sectors of the economy are recommended.

    Notizen: Abstract Amongst the environmental and social externalities generated by Australian agriculture are a number of risks both to the health and safety of communities living near sites of agricultural production, and to the end consumers of agricultural products. Responses to these potential risks – and to problems of environmental sustainability more generally – have included a number of programs to variously: define “best-practice” for particular industries; implement “Quality Assurance” procedures; and encourage the formation of self-help community “Landcare” groups. Taken together, these programs appear to deal comprehensively with both the social and environmental risks associated with agricultural production and products. However, these programs may also be interpreted as strategies that actually encourage the further intensification of agriculture, while attempting to reassure consumers that their food is safe and that farmers are doing “all they can” to protect the environment. Investigation of the Australian cotton and beef industries illustrates a number of strategies that have become evident between farmers, agri-science agencies, and the retail sector to manage these risks and define good farming practices in ways that satisfy their own perceived interests. Contrary to the image, therefore, of “green consumption” that is emerging as an integrated concern for “clean” (and thereby “healthy”) and sustainably produced foods, it appears that mainstream agricultural industries have bifurcated these concerns in ways that distract attention from production and processing methods, leaving conflict over on-farm production methods a characteristic only of those industries believed to have direct health impacts on nearby communities.

    Notizen: Abstract This analysis uses an analytical frameworkgrounded in political economy perspectives of theglobalization of the agro-food sector combined with acase study approach focusing on the Marine StewardshipCouncil (MSC) to inform discussions regarding thecharacteristics of societal regulation in thepost-Fordist era. More specifically, this analysisuses the case of the emergence of the MSC toinvestigate propositions regarding the existence of,and location of, nascent forms of a transnationalState. The MSC proposes to regulate the certificationof sustainable fisheries at the global level throughan eco-labeling program. The MSC was created in 1996by the transnational environmental organization theWorld Wildlife Fund and the transnational corporationUnilever. The emergence of the MSC has generatedheated discussion in fisheries management circles thatis in general divided along North/South lines. Thisanalysis indicates that the case of the MSC providesvaluable insights into the possible characteristics ofsupranational regulatory mechanisms that might emulatethe role of the nation-State in the post-Fordist era.

    Notizen: Abstract  The composition of terpenoid substances in needles of Pinus nigra Arnold with respect to air pollution is discussed. Trees grown in the urban environment of the city of Nitra, which is contaminated by immissions, and trees grown in the relatively clean environment of the Mlyňany Arboretum SAS were investigated. The urban environment caused a change in the species composition and the content of terpenes. In the city of Nitra needles of P. nigra contained a smaller number of terpenoid substances (12 terpenes) in comparison with the Arboretum (15 terpenes). At Nitra P. nigra contained four terpenes with a relative portion above 1% and at the Mlyňany Arboretum P. nigra needles contained six terpenes above 1%. At the polluted site citral, eugenol, and bisabolol are completely missing in the terpene pattern of needles and myrcene, carvone and alfa-humulene were notably lower. The decrease of the alfa-pinene content and the increase of the beta-pinene content in needles from Nitra significantly lowered the ratio of alfa-pinene to beta-pinene from 2.80 to 0.86.

    Notizen: Abstract For improvement of the accessibility and use of environmental information a prototype national reference center (CIMI) was constructed in the Netherlands in 1986. Target groups were identified on the basis of an analysis of the demand side. They were questioned about their needs in the field of environmental information. On the basis of these experiences an automated integrated system has been built that is composed of subsystems for reference to expertise in organizations (specialisms), literature, research, and databases of site-specific data. This system is also equipped with a thesaurus. The system has been tested and examined in several ways. The outcome of these independent tests and investigations confirm the usefulness of this center for information transfer. The reference center can be helpful in providing overviews on and structuring of environmental information in the Netherlands. The results of the activities have been presented in several ways and were described extensively in a number of reports.

    Notizen: Abstract One of the enduring facts of the human condition is that the earth's resources are finite and its environment fragile. It is also evident that human behavior is rarely based on an appreciation of these facts. While the outlook may be bleak, so are some of the proposed solutions. Reasonable people have suggested that, to survive, an environmentally enlightened authoritarian government must be adopted. This article suggests that such a solution is unworkable, in part because it fails to consider critical aspects of human nature. A framework is proposed for developing solutions compatible with human capabilities.

    Notizen: Abstract This article reviews the existing models of corporate social responsiveness and develops a theoretical framework with which to examine corporations' discretionary performance with respect to one social issue, that of the environment. Discretionary indicators of corporate response to environmental issues are developed and tested within this framework. Twelve companies from five different sectors were selected for the survey, based on prior knowledge of their commitment to environmental concerns. Primary data was collected from personal interviews, and secondary data was obtained from company documents, annual reports, and other forms of publically disclosed information. Empirical results varied, but certain voluntary indicators, such as composition of the board of directors, the environmental affairs function, community support, and the annual report are considered to provide strong indications of discretionary corporate performance. Philanthropy and company products proved to be less satisfactory indicators of corporate commitment to the environment. The aggregated results revealed a correlation between the final rankings of firms' discretionary environmental performance and whether those companies are process or product oriented. Linkages between discretionary elements and those of economic and legal requirements were not explored.

    Thema: Energietechnik
    Notizen: Abstract The functions of packaging are derived from product requirements, thus for insight into the environmental effects of packaging the actual combination of product and package has to be evaluated along the production and distribution system. This extension to all related environmental aspects adds realism to the environmental analysis and provides guidance for design while preventing a too detailed investigation of parts of the production system. This approach is contrary to current environmental studies where packaging is always treated as an independent object, neglecting the more important environmental effects of the product that are influenced by packaging. The general analysis and quantification stages for this approach are described, and the currently available methods for the assessment of environmental effects are reviewed. To limit the workload involved in an environmental assessment, a step-by-step analysis and the use of feedback is recommended. First the dominant environmental effects of a particular product and its production and distribution are estimated. Then, on the basis of these preliminary results, the appropriate system boundaries are chosen and the need for further or more detailed environmental analysis is determined. For typical food and drink applications, the effect of different system boundaries on the outcome of environmental assessments and the advantage of the step-by-step analysis of the food supply system is shown. It appears that, depending on the consumer group, different advice for reduction of environmental effects has to be given. Furthermore, because of interrelated environmental effects of the food supply system, the continuing quest for more detailed and accurate analysis of the package components is not necessary for improved management of the environmental effects of packaging.

    Notizen: Abstract When marketing environmentally responsible packaged products, the producer is confronted with consumer beliefs concerning the environmental friendliness of packaging materials. When making environmentally conscious packaging decisions, these consumer beliefs should be taken into account alongside the technical guidelines. Dutch consumer perceptions of the environmental friendliness of packaged products are reported and compared with the results of a life-cycle analysis assessment. It is shown that consumers judge environmental friendliness mainly from material and returnability. Furthermore, the consumer perception of the environmental friendliness of packaging material is based on the postconsumption waste, whereas the environmental effects of production are ignored. From the consumer beliefs concerning environmental friendliness implications are deduced for packaging policy and for environmental policy.

    Notizen: Abstract Groundwater contamination by agricultural chemicals is a major environmental pollution issue nation-wide. The regulatory agencies of towns and counties face the problem of finding a methodology for assessing the ground-water contamination potential of a large number of agricultural pesticides. Because of the spatial nature of the problem and the limited data availability for comprehensive pesticide movement models, a contamination potential index was employed for preliminary assessment. A specially designed geographic information system was used to create ground-water contamination likelihood maps for a 1500 km2 area. The results suggest that this methodology can be used successfully for evaluating the relative contamination potential of a large number of pesticides over large areas with limited input data. A tentative approach for using this method for monitoring and registration of pesticides is also discussed.

    Notizen: Abstract Environmental impact assessment (EIA) is based on the results of effect prediction. In general, there is much diversity in the expertise in the field of environmental prediction between the different categories of actors involved in EIA. In practice it became obvious in The Netherlands that the accessibility and comprehensibility of existing relevant information was insufficient. For improvement, a series of systematic handbooks on effect prediction, useful for all categories of actors, has been developed in The Netherlands. In this way, the selection of effect prediction methods to be used in concrete circumstances is improved and speeded up for all parties involved in environmental prediction. After a discussion of the purpose of the handbook, the realization and structure of the series are presented. Finally, the use and (potential) benefits of the handbooks for environmental management are indicated.

    Notizen: Abstract Even though “sustainable development” seems to have emerged as the development paradigm of the 1990s, a great deal of vagueness still surrounds the meaning, definition, and theoretical underpinnings of the concept. There is also a general lack of emphasis on the spatial dimension of sustainable development when developing relevant conceptual or environmental accounting frameworks. In clarifying the concept, this article proposes a definition that explicitly incorporates the temporal as well as the spatial dimension of sustainability. It also develops a logically consistent conceptual framework for the analysis and evaluation of sustainable development, following a spatial systems approach. Five interconnected aspatial subsystems or subsets of a spatial system are identified and their respective operational dimensions discussed. A proposed composite index calleddegree of stainable development (DSD) and its five component indicators are also outlined. The difficulties involved in operationalizing the DSD measure and the conceptual framework are noted, and the various tasks that need to be undertaken in this regard are specified. It is concluded that future research utilizing the proposed conceptual framework should not only foster the development of appropriate methodologies for the comparative evaluation of sustainable development at global, national, or regional scales, but also offer insights to appropriate decision makers at various levels regarding available options and alternative actions for the healthy development of their respective societies.

    Notizen: Abstract The Nature Conservancy is an international organization dedicated to the mission of conserving biodiversity throughout the world. By working in a nonconfrontational manner, an approach that has promoted both government and corporate sponsorship of its activities, The Nature Conservancy has developed symbiotic relationships with many electric utility companies. Drawing on the organization's experiences, and the experiences of the author as the President and Chief Executive Officer of The Nature Conservancy, five broad areas of cooperation between conservation organizations and the utility industry are explored: landmanagement agreements, mitigation projects, conflictavoidance programs, program support, and volunteer activities. The paper is concluded with comments on the future trends of biodiversity conservation, challenging the electric utility industry to become involved with conservation efforts by forming cooperative partnerships.

    Notizen: Abstract Although the French concern for environmental protection dates back several centuries, a committed movement toward environmental protection did not begin until the second half of the 19th century. The Romantic influence of Rousseau and others led to the formation of various societies aimed at protecting the French landscape. Until the most recent environmental crusades of the 1960s and 1970s, the cause of protecting the natural environment seemed to fall largely on the shoulders of scientists and anglers, who voiced their concern over increasing environmental degradation in pamphlets and recreational journals. Their pressure aided in the passage of legislation on water quality. During the 1960s, environmental organizations proliferated and, in league with student activists, played an important role in raising the environmental consciousness of the French. During the 1970s, these activists began to turn to traditional political mobilization as a way of drawing attention to their platform. Environmental activism reached its peak with the antinuclear rallies of the late 1970s. By the end of the 1970s, many environmental associations had grown up in the French culture, but the future of environmentalism remains questionable owing to a number of economic realities, including the oil crisis, which made nuclear power much more acceptable to the public.

    Notizen: Abstract The beliefs of Americans about the proper relationship between humans and their environment were profoundly affected by waves of immigration from Europe. Immigrants valued ownership of land, individuality, freedom, domination of nature, and technological development. These themes remain strong today as centerpieces of the American dominant social paradigm (DSP). That DSP has been reexamined and found wanting by an increasing proportion of Americans. This departure from the old DSP has progressed further among the public than among the elite who have a greater stake in preserving the status quo. Environmentalists constitute a vanguard trying to lead the people to a new, more environmentally oriented social paradigm. The beliefs of the old DSP and the new environmental paradigm (NEP) are contrasted in Table 2. Briefly, the NEP advocates stress love of nature rather than domination of it; compassion for other peoples, future generations, and other species; planning to avoid risk; limits to growth; fundamental social change; and a new structuring of politics. These two worldviews are likely to be in vigorous conflict for several decades in the USA. Social learning, spurred by deterioration of the old ways, is likely to lead Americans to a new perspective on their relationship to nature.

    Notizen: Abstract This essay evaluates the historical development and current background of human-environment relationships in Italy. The Italian landscape consists of very varied terrain, and periodically suffers from all kinds of natural hazard, especially earthquakes, landslides, floods, and accelerated soil erosion. Some measure of environmental conservation was achieved by the Etruscans and Romans, but the Classical period also marked the beginning of serious lowland waterlogging, malarial infestation, upland soil erosion, and deforestation, which all increased during the Middle Ages. From the Renaissance to the 18th century, there was a diffusion of planned landscapes and carefully managed estates; but by the 20th century, many rural areas could not support growing populations and much land was in need of improvement. Underdevelopment and latifundium agriculture increased the vulnerability to environmental hazards of the Mezzogiorno (Italian South), while the subsequent disappearance of the peasant culture seems not to have led to greatly improved conservation or land management. Poorly farmed or managed landscapes and poorly maintained historic towns have undergone some virtually irreversible degradation, especially with respect to landslides and earthquake damage. Elsewhere in Italy, unchecked urbanization, weak planning laws, and their inadequate enforcement have helped both to reduce environmental quality, by overdevelopment of valued landscapes, and to increase natural disaster vulnerability, by encouraging occupance of natural hazard zones. Although there are signs that the government is beginning to respond to the cumulative effect of environmental degradation, the measures are insufficient to reverse the overall trend toward decadence that characterizes human-land relationships in Italy.

    Notizen: Abstract The Soviet Union is one of the most physically and culturally diverse nations on earth. Its natural environment embraces a rich variety of resources and ecosystems, many of which, such as Lake Baikal, are of world significance. Culturally, it is comprised of over a hundred ethnic groups, belonging to eight major language groups and six major religions. However, two cultures are dominant: the Slavic group (which takes in 75% of the USSR population and 80% of its land area) and the Turkic-Islamic peoples who account for the large majority of the remainder. Owing to the highly centralized nature of the country's political-administrative system, however, the effect of culture or ethnic traditions in the resolution of national environmental issues is quite small. Major decisions regarding either specific conservation issues or basic environmental policies are made at the centralized level by ministerial, planning, and Communist Party officials, and are based on pragmatically refined ideological considerations, rather than on regional cultural attitudes. This pragmatic refining of ideological considerations will involve the weighing of specific economic and environmental imperatives, and deciding on appropriate trade-offs. To find cultural expression in environmental management, one would need to look closely at local projects and approaches in the various ethnic regions, particularly the non-Slavic ones.

    Notizen: Abstract During the last few years in the Netherlands an integrated environmental policy has been developed. Solving environmental problems by means of effective and efficient solutions requires that the entire environmental cycle be considered in order to take all relevant compartments and aspects into account. Four different phases can be identified during the treatment of an environmental problem by management: recognition, formulation, solution, and control. Some qualitative and quantitative aspects of the information demand of environmental policy are explored. Special attention is given to the consequences of the integral approach in environmental policy in terms of information requirements. The process of information supply starts with an analysis of the demand. Subsequently data from the environmental cycle have to be selected, aggregated, and presented adequately. Further, integrated environmental policy puts increased demands on the associative power of environmental information systems.

    Notizen: Abstract This article addresses the use of critical loads in optimized emission abatement strategies. Critical loads represent the maximum tolerable deposition possible without adverse impacts, a limit that is highly spatially variable. As deposition targets, critical loads cannot be satisfied at all receptors in Europe. Consequently, there is a need for alternative criteria that still relate to ecological indicators, yet that are feasible, consistent, and equitable. Two criteria are suggested: the relative critical load coverage and the relative deposition reduction. Deposition goals based on these criteria will guarantee that a specified fraction of ecosystems will attain target loads and thus will be protected from adverse environmental impacts. In areas that cannot achieve target loads with the best available control measures, deposition can be reduced to a specified fraction of the unabated level. Examples are presented that demonstrate their derivation and application of the two criteria. The criteria have been implemented in the European-scale Regional Acidification Information and Simulation (RAINS) model. Results obtained indicate that optimized emission strategies based on critical loads may be similar to emission strategies based on deposition reductions at certain levels of the two criteria. This suggests that it may not be necessary to utilize critical loads to formulate deposition targets. A second example shows the effect of excluding countries from European cost minimization. A country's participation can save costs with moderate deposition targets; however, significant costs can be imposed with low (stringent) deposition targets. These preliminary results have significant implications for multilateral negotiations.

    Notizen: Abstract Objective judgments, external to the judge, are compared with subjective, internal judgments. This analysis is made in the context of reaching regulatory decisions affecting the human environment. Examples given include evaluating the potential risk of industrial chemicals and comparing the potential effects of short- and long-term changes in land use. The analysis deals not with the decisions themselves, but rather with the kinds of questions that must be posed in orderto reach such decisions. Decision makers may spuriously distinguish objective from subjective types of judgment, though these are rarely wholly separate. Judges can hardly dispute about objective statements, if truly identical definitions are used. But subjective statements can reasonably be voted upon. Scientists, engineers, and economists represent logical or objective decision makers, tending to work in groups. Subjective thinkers include artists and performers, and others who often work alone. Moral and aesthetic aspects of questions, usually seen as intangible, are treated as if subjective. Financial decisions, usually viewed as tangible, are handled as objective problems. This mechanism for making decisions is well-established in environmental assessment. Though objective questions can be treated well in the monetary terms of cost-benefit analysis, subjective ones cannot. Mathematical and other variants are discussed in relation to the comparison of alternative types of tests.

    Notizen: Summary In trees, nutrient reserves built up in the previous year are of primary importance for early spring growth. Despite the relatively great importance of roots for nutrient storage, the root system should not be regarded as a special storage organ. Quantitatively, carbohydrates predominate in these reserves, but qualitatively N and other minerals are of more than minor significance. In roots carbohydrates are usually stored in insoluble form, mainly as starch; sorbitol is the predominant soluble compound in apple and peach. For nitrogen reserves, the soluble form predominates in roots, especially arginine in apple and peach, followed by asparagine. The level of reserves usually becomes maximal early in the winter. During leafing-out the reserves are drawn on until, later in the season, the supply of newly produced or absorbed nutrients exceeds the demand and replenishment occurs. The initial carbohydrate reserves do not determine the amount of new growth, whereas reserve nitrogen is of decisive importance for shoot growth vigour. Environmental factors such as light intensity and temperature affect the level of carbohydrates in roots; the concentration can be reduced by defoliation and summer pruning and increased by ample supply of nitrogen fertilizer in the autumn. The main cultural factors that influence nitrogen reserves are the amount and the time of nitrogen fertilization.

    Notizen: Abstract If a firm can influence its monitorability vis-à-vis an environmental regulator, it is shown that increasing the thoroughness of inspections induces the firm to substitute towards more transparent technologies, whilst increasing their frequency may cause substitution the other way. Perversely, when the effect of such substitution is taken into account, an increase in the frequency of inspections (or, equally, the stringency of penalties) may worsen the firm's environmental performance. The agency should favour more thorough inspections than existing theory suggests, particularly in sectors where the scope for such substitution is great. Moreover, when monitorability adjusts only sluggishly to policy shocks (because it is an embodied characteristic of capital, for example) the environmental impacts of increased frequency and increased thoroughness well over- and under-shoot their respective long-run impacts. In assessing regulatory reform, therefore, it is important to leave sufficient time for the class of adjustments identified to occur. The possibility of overshooting can be used as an alternative to existing ‘regulatory capture’ theories to explain why the efficacy of some classes of regulatory reform may fade through time.

    Notizen: Summary The pattern of N2-ase activity in clay-loam soil of Nile Delta was determined. However, unamended soil showed somewhat low activity: an amount of 18–95 mg N2 fixed/kg soil/year was calculated. Addition of glucose greatly enhanced such activity and efficiencies of N2-fixation increased with decreasing carbon source concentration. Highest activities (800 n moles C2H4/gh−1) and efficiencies (18.06 mg N2/g glucose added) were reported in soil amended with 1% glucose, adjusted to 50% W.H.C. and incubated at 30°C. Enrichment of the soil with straw lead to a significant nitrogen gain particularly under water-logged conditions. During a short period of 16 days 5.8–9.3 mg N2 were fixed/g straw added at the latter conditions.

    Notizen: Abstract Endogenous growth is generally built on a positive externality hypothesis which is the opposite of a negative externality caused by pollution. We study a linear technology with simple assumption: an aggregate capital stock which represents a learning by doing effect and a pollution flow proportional to production. In this framework, we analyse the precise effects on growth of the disutility of pollution and its interaction with the utility of consumption in an economy without abatement technology. The decentralized equilibrium always leads to unlimited growth, but optimal growth is often limited (the negative effect of pollution dominating the positive effect of learning by doing). In this case, the optimal policy which leads the decentralized economy to follow the optimal growth path is to tax capital; in contrast with the optimal subsidy policy in an economy without pollution. When an abatement technology is introduced, the optimal solution can lead the economy to unlimited growth, whatever the form of the utility function.

    Beschreibung: Policy makers in the United States often justify agricultural subsidies by stressing that agriculture is the engine of the rural economy. We use the increase in crop prices in the late 2000s to estimate the marginal effect of increased agricultural revenues on local economies in the U.S. Heartland. We find that $1 more in crop revenue generated 64¢ in personal income, with most going to farm proprietors and workers (59%) or nonfarmers who own farm assets (36%). The evidence suggests a weak link between revenues and nonfarm income or employment, or on population. Cuts to agricultural subsidies are therefore likely to have little effect on the broader rural economy in regions like the Heartland.

    Beschreibung: Farmers throughout the developing world face multiple sources of uninsured risk to agricultural production and household assets. In this paper, we present results from an experimental demand-elicitation exercise in rural Bangladesh to shed light on smallholder farmers' interest in formal insurance products. We propose a suite of insurance and savings products, and we randomly vary the price of one insurance option (area-yield insurance) and the presence of one of the savings options (group savings). Consistent with economic theory, farmers buy more of the insurance products that cover the risks they primarily face. However, because farmers are subject to a variety of risks, they do not focus on only one type of insurance; instead, they evenly split their endowment between life and disability insurance and agricultural insurance. Demand for area-yield insurance falls with price; we also observe important cross-price elasticities with other insurance products. The presence of group savings does not alter demand for insurance, though group savings is found to be a particularly popular risk management tool, especially when decisions are made in groups.

    Beschreibung: Which foreign direct investments are most affected by political instability? Analysis of quarterly greenfield investment flows into countries in the Middle East and North Africa during the period from 2003 to 2012 shows that adverse political shocks are associated with significantly reduced investment inflows in the non-resource tradable sectors. By contrast, investments in natural resource sectors and non-tradable activities appear insensitive to such shocks. Political instability is thus associated with increased reliance on non-tradables and aggravated resource dependence.

    Beschreibung: Our article contributes to the emerging micro-level strand of the literature on the link between local variations in weather shocks and conflicts by focusing on a pixel-level analysis for North and South Sudan between 1997 and 2009. Temperature anomalies are found to strongly affect the risk of conflict, whereas the risk is expected to magnify in a range of 24–31% in the future under a median scenario. Our analysis also sheds light on the competition over natural resources, in particular water, as the main driver of such relationship in a region where pastoralism constitutes the dominant livelihood.

    Beschreibung: In many Sub-Saharan African countries, farmers typically have a choice between selling their products to traders who travel between villages and markets and transporting their products to the nearest market themselves. Because of communities’ remoteness and poor communications with marketplaces, farmers’ uncertainty about market prices is usually high. Traders may take advantage of farmers’ ignorance of the market price and extract a rent from them by offering very low prices for their products. In this article, we model bargaining interactions between farmers and traders meeting at the farmgate and we study how price information affects the bargain and the balance of power. We show the conditions for Market Information Services (MIS) to be profitable for farmers and examine efficiency issues associated with asymmetric information. Finally, we test the model’s prediction that information results in positive individual gain for farmers using original survey data collected in the Northern region of Ghana. Specifically, we estimate the causal effect of a mobile-based MIS program on farmers’ marketing performances and find that farmers who have benefited from the MIS program received significantly higher prices for maize and groundnuts: about 10% more for maize and 7% more for groundnuts than what they would have received had they not participated in the MIS program. These results suggest that the theoretical conditions for successful farmer use of MIS may be met in the field.

    Beschreibung: Offering matching grants along with extension services is a common tool of agricultural development policy and has the potential to address some of the shortcomings of purely private or public extension. Yet the evidence for the effectiveness of programs that combine extension with matching grants is quite thin. We add to this evidence by evaluating the Uruguayan Livestock Program (ULP), a program that promoted the adoption of intensive management practices by small and medium-sized cattle producers by offering extension from private providers combined with matching grants for investments. Using inverse probability weighting as applied to an eight-year panel data set of cattle producers, we find that the ULP had large impacts on net sales and production of calves, but that program impacts on production and sales translated into modest net economic impacts overall. We examine the mechanisms that may have driven ULP impacts, and conclude that program impacts were likely caused by improved management practices rather than by loosening liquidity constraints on producers.

    Beschreibung: Why have policies aimed at reducing the demand for carbon not succeeded in slowing down global carbon extraction and CO 2 emissions, and why have carbon prices failed to increase over the last three decades? This comment argues that this is because of the Green Paradox, that is, the anticipation of sales by resource owners who try to preempt the destruction of their markets by green policies. Reviewing some of the conditions under which strong and weak versions of the Green Paradox may emerge, it is argued that there is little hope that green replacement technologies will impose hard price constraints that would keep long-run extraction within a fixed carbon budget and that, therefore, even strong versions of the paradox cannot easily be avoided.

    Beschreibung: In many developing countries, supermarkets are expanding rapidly. This affects farmers’ marketing options. Previous studies have analyzed welfare effects of smallholder participation in supermarket channels from a static perspective, using cross-section data. We develop a conceptual framework and use panel data to better understand participation and impact dynamics. The analysis focuses on vegetable producers in Kenya. Participation in supermarket channels is associated with income gains. However, many farmers have dropped out of the supermarket channel due to various constraints. The initial income gains cannot be sustained when returning to the traditional market. Organizational support may be needed to avoid widening income disparities.

    Beschreibung: This paper reviews the situation in the agricultural sector and food security in Cuba, and particularly the transformations that have (not) taken place since 1990. We compare the Cuban transition with transitions in other "transition countries" and show that Cuba does not easily fit into one of the transition patterns, and, in a way, has characteristics of "a bit of everything". To conclude, we discuss the (potential) effects of the recent policy changes and the new economic reforms that were announced.

    Beschreibung: We review evidence regarding the size and evolution of the "land rush" in the wake of the 2007–8 boom in agricultural commodity prices, and we study the determinants of foreign land acquisition for large-scale agricultural investment. The use of data on bilateral investment relationships to estimate gravity models of transnational land-intensive investments confirms the central role of agro-ecological potential as a pull factor. However, this finding contrasts the standard literature insofar as the quality of the destination country's business climate is insignificant, and weak tenure security is associated with increased interest for investors to acquire land in the country. Policy implications are discussed.

    Beschreibung: It is widely believed that oil prices impact food prices in developing countries. Yet rigorous evidence on this relationship is scarce. Using maize and petrol price data from east Africa, we show that global oil prices do affect food prices but primarily through transport costs, rather than through biofuel or production cost channels. We find that global oil prices transmit much more rapidly to the pump and then to local maize prices than do global maize prices, suggesting that the immediate effects of correlated commodity price shocks on local food prices are driven more by transport costs than by the prices of the grains themselves. Furthermore, we present suggestive evidence that, for markets furthest inland, changes in world oil prices have larger effects on local maize prices than do changes in world maize prices.

    Beschreibung: Natural resource abundance is a blessing for some countries, but a curse for others. We show that differences across countries in the degree of fiscal decentralization can contribute to this divergent outcome. Using a large panel of countries covering several decades and various fiscal decentralization and natural resource measures, we provide empirical support for the novel hypothesis. We also study a model that combines political and market mechanisms under a unified framework to illustrate how natural resource booms may create negative effects in fiscally decentralized nations.

    Beschreibung: The yield potential of a set of improved rice management practices, known as the System of Rice Intensification (SRI), has attracted much attention. Yet we know surprisingly little about SRI's socio-economic impact. Using data from Indonesia in 2009, this study assesses the impact of SRI on household incomes and child schooling. We find that SRI generates significant estimated yield gains. However, because SRI induces a reallocation of family labor from non-farm to farm, SRI users enjoy no household income gains. Despite the increased labor demand for farming, we find no evidence that SRI has a child labor effect.

    Beschreibung: This paper studies the effect of political regime transitions on public policy using a new data set on global agricultural and food policies over a 50-year period (including data from 74 developing and developed countries over the 1955–2005 period). We find evidence that democratization leads to a reduction of agricultural taxation, an increase in agricultural subsidization, or both. The empirical findings are consistent with the predictions of the median voter model because political transitions occurred primarily in countries with a majority of farmers. The results are robust to different specifications, estimation approaches, and variable definitions.

    Beschreibung: In times of highly volatile commodity markets, governments often try to protect their populations from rapidly rising food prices, which can be particularly harmful for the poor. A potential solution for food-deficit countries is to hold strategic reserves that can be called on when international prices spike. But how large should strategic stockpiles be, and what rules should govern their release? In this paper, we develop a dynamic competitive storage model for wheat in the Middle East and North Africa region, where imported wheat is the most significant component of the average diet. We analyze a strategy that sets aside wheat stockpiles, which can be used to keep domestic prices below a targeted price. Our analysis shows that if the target price is set high and reserves are adequate, the strategy can be effective and robust. Contrary to most interventions, strategic storage policies are counter-cyclical, and when the importing region is sufficiently large, a regional policy can smooth global prices. Simulations indicate that this is the case for the Middle East and North Africa region. Nevertheless, the policy is more costly than a procyclical policy similar to food stamps that uses targeted transfers to directly offset high prices with a subsidy.

    Beschreibung: This paper uses framed choice experiments to examine the preferences of smallholder farmers in Malawi regarding alternative policy-based incentives to adopt conservation practices that reduce soil erosion and increase yields. The policy incentives offered in the choice experiments included an ideal index-based crop insurance contract, an index insurance contract with basis risk, cash payments, and fertilizer subsidies. Prior to implementing the choice experiments, the farmers participated in a workshop utilizing small group-based dynamic learning games that demonstrated how index-based crop insurance contracts function. The choice experiment results indicate that most farmers preferred cash payments to index insurance contracts, even when the insurance contracts offered substantially higher expected returns. Further, more risk averse farmers were more likely to prefer cash payments than less risk averse and risk loving farmers.

    Beschreibung: This article examines the substitutability, productivity, efficiency, and evolution of an important agrarian nonmarket institution—labor sharing. Analysis of field-level data on forest clearing through time among Amazonian shifting cultivators reveals that ( a ) family, hired, and cooperative labor are perfect substitutes, and hired and cooperative labor are equally productive, and both are more productive than family labor; ( b ) the combination of labor market and labor sharing makes productivity-adjusted total labor use unconstrained by household and network endowments (i.e., efficient labor allocation); and ( c ) as labor composition is constrained by network endowments and liquidity, credit policies alter both labor composition and labor network formation.

    Beschreibung: This paper deals with the determinants of out-farm migration across the European Union (EU) regions focusing on the role played by CAP payments. We add to the existing literature in three main directions. First, our analysis has broad coverage (150 EU regions over the 1990–2009 period); second, we work on the entire portfolio of CAP instruments; third, we rely on modern panel data methods. Results show that standard drivers, such as the relative income and the relative labour share, are important determinants of out-farm migration. Overall, CAP payments significantly contributed to maintain job in agriculture, though the magnitude of the economic effect has been quite moderate and heterogeneous across policy instruments. Pillar I subsidies exerted an effect more than two times greater than that of Pillar II payments.

    Beschreibung: This article presents a new approach to identifying poverty traps in East African pastoralist communities. A flexible semiparametric estimation procedure is used to identify a bifurcation in the propensity to engage in the asset-based, mobile herding livelihood, in comparison to the sedentary alternative, as a function of herd size. The identified threshold is consistent with previous evidence on poverty traps based on modeling herd stock dynamics. The approach contributes to an emerging literature that seeks to identify poverty traps through testing the implications of the posited behavioral mechanism behind the trap, as opposed to directly modeling asset dynamics. The approach is further employed to provide complementary evidence on the relationship between ability and assets in sustaining mobile pastoralism.

    Beschreibung: Recent years have seen considerable interest in the impact of contract farming on farmers in developing countries, motivated out of belief that contract farming spurs transition to modern agriculture. In this article, we provide a thorough review of the empirical literature on contract farming in both developed and developing countries, using China as a special case of the latter. We pay careful attention to broad implications of this research for economic development. We first find empirical studies consistently support the positive contribution of contract farming to production and supply chain efficiency. We also find that most empirical studies identify a positive and significant effect of contract farming on farmer welfare, yet are often unable to reach consistent conclusions as to significant correlates of contract participation.

    Beschreibung: We estimate the impact of Malawi's Farm Input Subsidy Program using an economy-wide approach. This approach yields benefit-cost ratios about 60% higher than existing partial equilibrium studies, a result of our accounting for indirect benefits. Fertilizer response rates remain the determining parameter for benefit-cost ratio levels. Even with lower-end response rates, the program is pro-poor and generates double-dividends through higher and more drought-resilient yields. Overall, for macro-economically significant programs, our approach strongly complements survey-based evaluations. For Malawi, our results buttress arguments for a focus on program improvements.

    Beschreibung: The longstanding "cash versus food" debate has received renewed attention in both research and practice. This paper reviews key issues shaping the debate and presents new evidence from randomized and quasi-experimental evaluations that deliberately compare cash and in-kind food transfers in ten developing counties. Findings show that relative effectiveness cannot be generalized: although some differences emerge in terms of food consumption and dietary diversity, average impacts tend to depend on context, specific objectives, their measurement, and program design. Costs for cash transfers and vouchers tend to be significantly lower relative to in-kind food. Yet the consistency and robustness of methods for efficiency analyses varies greatly.

    Beschreibung: This paper provides an overview of the impact that one-time changes in commodity and other prices have on household welfare. It begins with a collection of stylized facts related to commodities based on household survey data from Latin America and Africa. The data uncovers strong commodity dependence on both regions: households typically allocate a large fraction of their budget to commodities, and they often also depend on commodities to earn their income. This income and expenditure dependency suggests sizable impacts and adjustments following commodity price shocks. The article explores these effects with a review of the relevant literature. The authors study consumption and income responses, labor market responses, and spillovers across sectors. The paper provides evidence on the relative magnitudes of various mechanisms through which commodity prices affect household (and national) welfare in developing economies.

    Beschreibung: India and China have the largest farm-household populations in the world—populations that are also among the poorest. Among the many factors that affect farm livelihoods, access to credit has been identified as a significant barrier preventing the escape from poverty. While there has been significant research on credit constraints in developing countries, there is surprisingly little information pertaining to the actual impacts of credit constraints on household well-being. The objective of this paper is to investigate the impacts of credit constraints on various factors affecting farm households, such as physical and human capital formation, agricultural inputs applications, consumption smoothing, and wage-seeking behavior using direct elicitation. This paper contributes to the literature and policy debates by comparing the effects of credit constraints in China and India as surveyed in 2008–2009. The analytical results and data demonstrate that binding credit constraints adversely affect a broad range of production and livelihood choices. We empirically show that credit constraints negatively affect food consumption, farm input applications, and health and educational attainments.

    Beschreibung: Many smallholder families are exceptionally prone to potentially catastrophic decreases in their incomes and access to food. Over the past decade, therefore, policy makers and economists have increasingly focused on potential mechanisms for expanding risk management strategies available to those families. Commercially provided weather-based index insurance products, perhaps partially funded by subsidies, have been of particular interest because of their apparent potential to provide payments to smallholder families when they are most in need of help. However, the empirical evidence from a wide range of studies indicates that, absent relatively substantial subsidies, small holder farmers will not purchase commercially priced index products or even "all risk" products where payments are tied to the farm's crop losses. There are three important reasons why this is the case. First, smallholder farmers already have many ways of managing their risks, including informal community-based initiatives, on-farm production decisions and off-farm work. Second, index insurance schemes are subject to considerable basis risk; families often do not receive an index insurance indemnity when they experience a substantial crop loss on their farms. Third, the fixed costs of delivering crop insurance to smallholders make such coverage expensive. The potential market for weather index insurance therefore may be limited to insuring relatively large groups of farmers, either directly or indirectly though providing micro finance and other lending institution with coverage against widespread loan defaults associated with catastrophic events like major droughts. Alternatively, weather indexes could simply be used to more accurately target emergency aid.

    Beschreibung: We study the effect of alleviating the information asymmetry regarding product quality that is widespread in contracts between agricultural producers and buyers in developing countries. Opportunistic buyers may underreport quality levels to farmers to reduce the price that they have to pay. In response, farmers may curb investment, thereby negatively affecting farm productivity. In an experiment, we entitle randomly selected smallholder dairy farmers in Vietnam, who are contracted by a large company, to independently verify milk testing results. Results indicate that treatment farmers use 12% more inputs, and they also increase their output significantly. Some wider research and policy implications are discussed.

    Beschreibung: Recent expansions in biofuel production have led to concerns about an emerging "new relationship" between energy prices and the prices of agricultural feedstock for biofuel. We provide new econometric evidence on this relationship using common trend-common cycle decompositions to estimate long-run and short-run co-movement across various energy and agricultural prices. We also test for the presence of regime changes that may alter the relationship between energy and agricultural feedstock prices under certain conditions. We find that co-movements between energy and agricultural feedstock prices tend to dissipate in the long-run, which has important implications for biofuel and food policy.

    Beschreibung: Many companies are adopting environmentally friendly management practices in developed countries. However, the benefits of a corporate environmental strategy are less clear in emerging (developing and transition) economies, where environmental regulations may be poorly enforced and social pressures to comply are weak. Thus it is important for business leaders, policymakers, and environmental activists to understand the causes and consequences of corporate environmental strategy in these economies so that they are able to implement effective strategies, develop useful policies, and promote meaningful activities, respectively. Drawing on both the theoretical and empirical literature, this article examines a broad array of drivers behind corporate environmental strategies including internal characteristics of firms, market pressures, and pressures from government and civil society. The empirical findings for developing economies (i.e., those whose physical and human resources, along with institutions, are still developing) suggest that government and civil society provide weak incentives for corporate environmental compliance, foreign ownership and foreign customer pressure improve environmental management practices, and information disclosure programs offer some promise for improving corporate environmental performance. The empirical findings for transition economies (i.e., those transitioning from reliance on the government’s allocation of resources to market-based allocations) also suggest a positive, albeit weaker, role for foreign ownership and foreign customer pressure in improving firms’ environmental performance. However, the findings also indicate that government policies, such as stricter enforcement, granting of permits, and higher rates for emission charges, are more effective in transition economies than in developing economies.

    Beschreibung: The spatial distribution of organic farming can be explained by combining the traditional location factors that account for spatial heterogeneity with the concept of spatial dependence. We present a theoretical model that explains a farmer's decision to convert to organic farming, and this conceptual framework is then implemented in a spatial lag model by using secondary data for Germany at the county level. The results support the assertion that agglomeration effects are important in the organic farming sector. Potential policy implications include a concentration of development measures for organic farming in certain regions.

    Beschreibung: Large-scale experiments with the decentralization of forest management in South Asia have changed the relationship between forests, public institutions that manage forests, and rural households. But have these institutional changes led to reductions in forest degradation and improvements in welfare? It is important to ask this question because reducing deforestation and degradation is a public policy goal, and rural households depend on forests to meet their subsistence needs. This article examines the literature on the Joint Forest Management program in India and the Community Forestry Programme in Nepal. The emerging evidence suggests that community forest management may indeed be contributing to improved forest health in South Asia. However, the impacts on household welfare appear to be far more varied but have also been less carefully studied. The article concludes that policies that further clarify resource rights and support local monitoring would strengthen and improve community forestry. ( JEL : O13, Q23, Q28, Q56)

    Beschreibung: Various regions have recently proposed the creation of clusters around large-scale mining. However, until the 1980s, mining regions were predominantly considered productive enclaves. This article analyzes the case of the Antofagasta Region, the main mining region in Chile. A descriptive analysis is put forward that addresses the ideal types of the mining cluster and enclave, establishing as criteria of comparison the mechanisms proposed by Marshall as sources of agglomeration economies. Despite strong growth, the Antofagasta Region approximates more a mining enclave than a cluster. This implies the need to revise and adapt the concept of enclave to the current reality.

    Beschreibung: This paper investigates the economic value of municipal, private, and community-managed water services in Guatemala through a hedonic analysis of rental housing prices observed in 2006. Hedonic models are jointly estimated with water service choices using a maximum simulated likelihood approach in order to control for potential endogeneity. Findings indicate that the value of piped water depends on the type of water utility. The estimated value of municipal services is at least 15 times as much as the average water bill, while value estimates are not significant for private and community-managed systems. Value differentials are discussed considering the performance of water utilities and their institutional arrangements.

    Beschreibung: We estimate the effects of changes in cotton adoption on children’s schooling and child labor in rural Burkina Faso. Using time and spatial variations, we find evidence that expansion of cotton farming has led to an increase in enrollment and to a reduction of participation in child labor for girls. There are, however, no detectable effects on boys. In theory, cotton adoption could increase household income, leading to increased demand for schooling and reduced child labor. On the other hand, because children are productive on cotton farms, adoption of cotton could increase the opportunity cost of child time and the demand for child labor. We provide suggestive evidence showing that boys are more productive than girls on cotton farms. Taken together, the results suggest that the income effect from cotton adoption might have been larger than the wage effect for girls, hence the overall positive impacts on school enrollment for girls.
