    Notes: Abstract Tropical deforestation provides a significant contribution to anthropogenic increases in atmospheric CO2 concentration that may lead to global warming. Forestation and other forest management options to sequester CO2 in the tropical latitudes may fail unless they address local economic, social, environmental, and political needs of people in the developing world. Forest management is discussed in terms of three objectives: carbon sequestration, sustainable development, and biodiversity conservation. An integrated forest management strategy of land-use planning is proposed to achieve these objectives and is centered around: preservation of primary forest, intensified use of nontimber resources, agroforestry, and selective use of plantation forestry.

    Brazilian Amazonia: Industrial development and environmental monitoring (1994)

    Notes: Abstract After a critical analysis of the strategies for conservation of the environment in Latin America and of large-scale development projects (agriculture and livestock raising, mining and electrical power plants) in the Amazon region of Brazil, this paper deals with the use of high-resolution satellite imagery for environmental monitoring. Two areas were considered in the study, Tucurui and Altamira. Spot/XS and Landsat/TM multispectral images were used, together with color aerial photographs of these areas. A computer-assisted visual interpretation procedure was employed to analyze images, and linear multispectral transformation was applied in selected subscenes in order to improve information extraction. The results indicate that high-resolution satellite imagery is generally compatible with the scale of the environmental problems in Amazonia and is a very efficient source of detailed information at a local scale on many aspects of the environment, in particular for monitoring changes over time in selected areas. Therefore, commercial satellite imagery, processed by specialized software, can accommodate a variety of analysis needs for decision makers and can also be an effective means of verification of international agreements on conservation of the environment in Amazonia.

    Journalists' views of advertiser pressures on agricultural news (1994)

    Notes: Abstract All major journalism ethical codes explicitly state that journalists should protect editorial copy from undue influence by outside sources. However, much of the previous research on agricultural information has concentrated on what information various media communicate (gatekeeping studies) or communication's role in increasing innovation adoption (diffusion studies). Few studies have concentrated specifically on organizational and structural constraints that might adversely affect agricultural journalists' ethical standards; those that have, focus largely on farm magazines. A study of newspaper reporters who cover agricultural news found that the most pressing ethical concern is the effect of advertiser (agri-business) pressure on editorial copy, and that their concerns in general parallel those of farm magazine writers and editors. The majority reported being in situations in which they might be exposed to advertiser pressure, including pressures to change or withhold editorial copy. Large minorities suggested that advertising pressures affect the overall environment in which agricultural journalists work, and more than one in ten said they allow advertiser pressures to influence editorial decisions. The newspaper reporters who cover agricultural beats showed slightly more resistance to advertiser pressure than did farm magazine editors in a parallel study.

    Land use change in the Amazon estuary: Patterns of caboclo settlement and landscape management (1994)

    Notes: Abstract Landsat TM scenes for 1985 and 1991 are used to produce a georeferenced map of land cover and land use for an area of the Amazon estuary inhabited by three populations of caboclos with distinct patterns of land use. This information is combined in a geographic information system with ethnographic and survey research carried out over the past 5 years to develop representative spectral “signatures” which permit measurement and differentiation of land uses and the detection of change even between small areas of managed floodplain forest and unmanaged forest, and between three distinct age/growth classes of secondary succession following deforestation. Implementation of these procedures permit the scaling up or down of research at different resolutions. Three distinct patterns of land use are examined with differential impact on the environment. Mechanized agriculture at one site has eliminated virtually all the mature upland forest and is now dominated by secondary successional vegetation. The more traditional system of diversified land use at the next site shows a subtle cycling of flooded forest to managed palm forest through time in response to the price of palm fruit and cycling in the use of fallow land. A third site, based on palm fruit extractivism, shows minimal changes in land cover due to persistent specialization on management of flooded forest extraction. There is little evidence that the community with the greatest impact on forest cover is any better off economically than the two communities which have minimal impact on the landscape. This study suggests how a balance between use and conservation in Amazonia may be achieved in floodplain and estuarine areas, and the effectiveness of monitoring these types of land cover from satellite platforms.

    The effect of agricultural discharge on striped bass (Morone saxatilis) in California's Sacramento-San Joaquin drainage (1994)

    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract The striped bass (Morone saxatilis) population of the Sacramento-San Joaquin Delta has declined approximately 80% since the mid-1970s. This decline has been attributed to factors such as water diversions, pollution and reduced abundance of food organisms. One source of potential pollutants is agricultural return water. The Colusa Basin Drain discharges water from over 150 000 acres and can account for over 20% of the flow of the Sacramento River. Because discharge occurs at the same time striped bass are spawning, early developmental stages could be adversely affected. Toxicity studies conducted over a 3 year period consistently demonstrated acute toxicity to striped bass larvae and to opossum shrimp (Neomysis mercedis), an important food organism for juvenile striped bass. Acute toxicity was also demonstrated with striped bass embryos. In addition, a model based on pesticide use more effectively predicted striped bass recruitment during the period of decline than did a model based on historically important river flows and delta diversions. These studies indicate that agricultural return water should not be disregarded when considering potential causes of the decline of striped bass.

    Spatial systems approach to sustainable development: A conceptual framework (1993)
    Springer
    Environmental management 17 (1993), S. 179-186

    ISSN: 1432-1009

    Notes: 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.

    Doubling sockeye salmon production in the Fraser River—Is this sustainable development? (1993)

    Notes: Abstract We evaluate a proposal to double sockeye salmon production from the Fraser River and conclude that significant changes will be required to current management processes, particularly the way available catch is allocated, if the plan is to be consistent with five major principles embodied in the concept of sustainable development. Doubling sockeye salmon production will not, in itself, increase economic equity either regionally or globally. Developing nations may actually be hindered in their attempts to institute other, nonsalmon fisheries in the North Pacific Ocean as a result of the possible interception of salmon. Further, other users of the Fraser River basin will have to forgo opportunities so that salmon habitat can be conserved. If doubling sockeye salmon production is to meet the goal of doing more with less, it will be necessary to develop more efficient technologies to harvest the fish. If increasing salmon production is to reflect the integration of environmental and economic decision making at the highest level, then a serious attempt must be made to incorporate environmental assets into national economic accounting. Finally, to promote biodiversity and cultural self-sufficiency within the Fraser River basin, it will be important to safeguard the small, less-productive salmon stocks as well as the large ones and to allocate a substantial portion of the increased production to the Native Indian community.

    Environmental planning, ecosystem science, and ecosystem approaches for integrating environment and development (1993)

    Notes: Abstract Currently popular concepts such as sustainable development and sustainability seek the integration of environment and development planning. However, there is little evidence that this integration is occurring in either mainstream development planning or environmental planning. This is a function of the history, philosophies, and evolved roles of both. A brief review of the experience and results of mainstream planning, environmental planning, and ecosystem science suggests there is much in past scientific and professional practice that is relevant to the goal of integrated planning for environment and development, but still such commonly recommended reforms as systems and multidisciplinary approaches, institutional integration, and participatory, goal-oriented processes are rarely achieved. “Ecosystem approaches,” as developed and applied in ecology, human ecology, environmental planning, anthropology, psychology, and other disciplines, may provide a more transdisciplinary route to successful integration of environment and development. Experience with ecosystem approaches is reviewed, their advantages and disadvantages are discussed, and they are compared to traditional urban and regional planning, environmental planning, and ecosystem science approaches. Ultimately a synthesis of desirable characteristics for a framework to integrate environment and development planning is presented as a guide for future work and a criterion for evaluating existing programs.

    A framework for modelling economy-environment-development relationships based on dynamic carrying capacity and sustainable development feedback (1993)

    Notes: Abstract A large literature exists that deals with economic issues of development and growth. It includes various approaches that can be classified as formal-theoretical, empirical-statistical and qualitative-verbal. Recently, the issue of sustainable development has been discussed much, which has given rise to some novel views on the relationship between development and environment. Most of these contributions utilize a more or less qualitative approach. A comprehensive inquiry of the relationship between economy, development, growth and environment may include an analytical approach as well. An analytical framework is proposed here for studies of environment-economy-development relationships that separates between economy, development, environment, and value system. A distinction is made between direct and indirect economy-environment interactions. To overcome disadvantages of assumptions of determinism in long term analysis a sustainable development feedback mechanism is proposed. It reflects anticipative behaviour to natural environmental changes in making long term decisions. This can be seen as a specific element of endogenous growth, namely one based on environmental factors. To illustrate the ideas a number of theoretical models are discussed that can be regarded as dynamic formal extensions of the concept of carrying capacity. Different cases include combinations of internal and external feedback mechanisms to an economy. The results demonstrate that in addition to behaviourial patterns that have been obtained by more complex studies other patterns may emerge.

    Abatement of agricultural pollution and economic incentives: The case of intensive livestock farming in France (1993)

    Topics: Energy, Environment Protection, Nuclear Power Engineering , Economics
    Notes: Abstract Amongst possible economic incentives to encourage reduced nitrate contamination of water, this paper emphasizes a nitrogen tax as a possible solution. This finding is based on models estimated from panel data for 100 intensive livestock farms. For each farm a threshold is established (nitrogen units which can be spread per hectare without damage) above which there is an excess of nitrogen. The 100 farms can consequently be classified into two subsamples. The demand for nitrogen is derived for each sub-sample using the dual approach. Both categories are pooled together and a tobit model is estimated. This is used to derive total nitogen demand if all farms were under the threshold. A mineral nitrogen tax would lead to a reduced nitrate concentration in water supplies, because of a more efficient use of organic nitrogen together with a reduction in the use of mineral nitrogen in crop production.

    Notes: Abstract An interdisciplinary course was designed as an introduction to the applications of, and the socio-economic issues associated with, biotechnology. College students enrolled in the course were surveyed prior to the first formal lecture, and again upon completion of the course. Assessment was made of the impact of the educational materials on the attitudes and perceptions of the students toward the applications of biotechnology to agriculture. Data were collected for the first three semesters in which the course was offered. Answers to survey questions were analyzed on a before and after basis. It was found that students were very accepting of biotechnology prior to taking the course, despite a generally low level of exposure to this type of technology. The course was effective in increasing the knowledge base of the students, but not as effective in allaying their perceptions of risks associated with biotechnology.

    Basic principles of agroecology and sustainable agriculture (1993)

    Notes: Abstract In the final analysis, sustainable agriculture must derive from applied ecology, especially the principle of the regulation of the abundance and distribution of species (and, secondarily, their activities) in space and time. Interspecific competition in natural ecosystems has its counterparts in agriculture, designed to divert greater amounts of energy, nutrients, and water into crops. Whereas natural ecosystems select for a diversity of species in communities, recent agriculture has minimized diversity in favour of vulnerable monocultures. Such systems show intrinsically less stability and resilience to perturbations. Some kinds of crop rotation resemble ecological succession in that one crop prepares the land for successive crop production. Such rotations enhance soil organic processes such as decomposition and material cycling, build a nutrient capital to sustain later crop growth, and reduce the intensity of pest buildup. Species in natural communities occur at discrete points along the r-K continuum of reproductive maturity. Clearing forested land for agriculture, rotational burning practices, and replacing perennial grassland communities by cereal monocultures moves the agricultural community towards the r extreme. Plant breeders select for varieties which yield at an earlier age and lower plant biomass, effectively moving a variety towards the r type. Features of more natural landscapes, such as hedgerows, may act as physical and biological adjuncts to agricultural production. They should exist as networks in agricultural lands to be most effective. Soil is of major importance in agroecosystems, and maintaining, deliberately, its vitality and resilience to agricultural perturbations is the very basis of sustainable land use.

    Notes: Abstract The 1988 drought conditions, which prevailed over the southern portion of the Canadian prairie provinces, resulted in severe impacts on agriculture, water resources, forestry, and waterfowl production. In this paper, the climatological aspects of the drought are reviewed and the impacts of the drought are described. In addition, a number of the environmental factors that may have aggravated the drought's impacts are discussed. Processes contributing to the 1988 drought are considered in terms of their scales, relative importance and possible effects. It was evident from the information needs of government agencies and private businesses which had to cope with the effects of the 1988 drought, that studies are needed to effectively monitor drought and adjust to its impacts. In this paper, these needs are discussed; several specific hypotheses concerning drought-related processes are advanced and a framework for addressing the scientific aspects of droughts on the Canadian prairies is proposed. It is anticipated that many of these identified research needs and opportunities are applicable to other drought-prone areas of the world.

    Change in a petrified forest and implications towards management (1992)

    Notes: Abstract The Gallatin Petrified Forest of Montana, USA, is a unique resource. The extensive area of the fossil forests, the numerous petrified trees in upright positions, and the large number of vertical layers of “successive” forests are unparalleled in the world. Collection by permit is permitted, but damage to the petrified forest by indiscriminate collection occurs. To assess the impact, a comparative examination of replicate (over 13 yr) photography of selected specimens was undertaken. The amount of change over time, the possible cause of change, and the relationship of the location of the specimen to that amount of change were determined. It was found that although considerable loss continues, impacts prior to a 1973 collection policy were most severe. There was more loss by natural erosion than by collection, but the collections are additive to the natural changes. Size of petrified outcrops and the steepness of the slope on which they were found did correlate with the amount of natural change occurring over time. Human-induced change was associated with the distance of the outcrops from the main trailheads and the specimen size. This method provides a tool with which to monitor impacts and develop a future policy aimed towards conservation of a unique resource in light of the need for appreciative recreation and some specimen collection. Recommended changes in present management policy are provided.

    Notes: Abstract Burning fossil fuel in the North American continent contributes more to the CO2 global warming problem than in any other continent. The resulting climate changes are expected to alter food production. The overall changes in temperature, moisture, carbon dioxide, insect pests, plant pathogens, and weeds associated with global warming are projected to reduce food production in North America. However, in Africa, the projected slight rise in rainfall is encouraging, especially since Africa already suffers from severe shortages of rainfall. For all regions, a reduction in fossil fuel burning is vital. Adoption of sound ecological resource management, especially soil and water conservation and the prevention of deforestation, is important. Together, these steps will benefit agriculture, the environment, farmers, and society as a whole.

    Notes: Abstract This paper reconsiders two widely held hypotheses about the effects of the green revolution, that it led to biological simplification and instability. The hypothesis of biological simplification (genetic erosion) is tested with evidence from Andean agriculture, where farmers maintain a significant degree of crop diversity even as they adopt modern crop varieties. The hypothesis of increased instability is tested with evidence from Asia where wheat and rice yields show no general pattern of increased instability. Neither of these hypotheses is confirmed. The conventional wisdom about the green revolution should be reconsidered with emphasis on resilience and variation in modernizing farming systems.

    Notes: Abstract Evaluation of conservation education programs can: (1) provide accountability in demonstrating a program's worth, (2) offer an opportunity for receiving feedback and improving programs, (3) further our understanding of the process of program development, and (4) promote conservation education by substantiating claims about its benefits. The Planning-Process-Product systems evaluation model provides feedback needed for making decisions about the development, implementation, and outcome of a program. Planning evaluation was useful in assessing the needs, goals, opportunities, and constraints of a number of programs in Costa Rica and Belize, such as a forestry education project and a zoo outreach program. It provided a basis for making planning decisions incorporating specific objectives, such as the reforestation of a region or a change in knowledge and attitudes in program participants. Process evaluation provided a Costa Rican sustainable development program with feedback during its implementation and enabled it to modify and improve its newsletter for local farmers and its ecology classes for school children. Product evaluation assessed project accomplishments, such as the $700,000 raised by the Children's Rainforest group and the 20 miles of riparian land under conservation management as part of the Belize Community Baboon Sanctuary project. Outcomes are compared with the programs original monetary or land management objectives to determine the success of the programs and to provide feedback for improvement.

    Notes: Abstract The Central Himalayan region is suffering from severe ecological problems as a consequence of deforestation and that threatens the subsistence population of the region. We analyze this problem and propose a plan for ecologically sustainable development for the region based on an analysis of the interrelationships of various ecosystems, particularly cropland and forest ecosystems, around which most human activities are concentrated. Each energy unit of agronomic yield leads to expenditure of about 12 energy units of forest/grazing land energy. Because with rapidly declining forest area, this form of agriculture is no longer sustainable and cannot be converted into a fossil fuel-based agriculture, we propose that agriculture in the mountain region has to be largely replaced with farm forests to revitalize the environment and to generate the basic needs of the subsistence economy of the hill population whose food grain needs can be met from the plains. We conclude by describing the advantages that are likely to accrue to the people for their long-term future. In terms of both energy and money, the value of resources collected from the forest to support agriculture in the present systems far exceeds the value of food grain that would be required to enable the proposed farm forest-based systems to function. At regional level, the proposed system would generate more energy than the existing systems, not only because the productivity of forest is about tenfold greater than that of cropland, but also because the proposed plan promotes recovery of various ecosystems.

    Towards a sustainable and efficient use of manure in agriculture: The Dutch case (1991)

    Notes: Abstract Rapid increases in livestock production in the Netherlands have changed manure from a valuable input into a mere waste product. This is especially true for the southern and eastern parts of the country, where specialized pig and poultry farms have concentrated on sandy soils. As these farms generally own very little land, they largely depend on imported feedstuffs. As a consequence, manure is applied to the land in such large quantities that serious environmental problems have resulted: (1) eutrophication of surface water by phosphate emissions; (2) pollution of groundwater by nitrate emissions; and (3) acidification by ammonia emissions. In the last few years the Dutch government has developed a manure policy to counteract these effects. Our analysis of that policy has revealed at least three fundamental defects, which render the manure policy ineffective and inefficient. In this paper proposals are made to remove the defects in current manure policy. Much attention is paid to the problem of designing a mixture of policy instruments which is both effective as well as efficient in limiting the environmental problems caused by manure. It is shown that the use of financial incentives in regulation can substantially improve the efficiency of the manure policy. Finally, the main economic consequences of the proposed policy are examined for the public sector as well as for the agricultural sector.

    Notes: Abstract This article examines the concept of sustainability (sustainable development, sustainable societies) with a view to providing a means of considering the idea in such a way as to be more useful to concerns of policy. A brief background is given, covering the historical development of the concept, the constituent ecological and social concerns that lie behind it, and some aspects of the sustainability debate in Australia. Some attributes of a sustainable future, as evident from the literature, are listed. The value base of the concept is recognized, and the correct place for sustainability concerns is identified within a simple policy-making model. The complexity of such a model in the real world is explored using a list of thecontexts of sustainability, illustrated with examples from Australian natural resource management. Finally, the more dynamic and flexible nature of patterns of production and consumption in more sustainable societies is recognized and explained, as are two guiding directives to be applied in the search for models which display characteristics of sustainability.

    Notes: Abstract Because the agriculture/food sectors appear to be driven by short-term economic and political forces, cheap energy, and agricultural-chemical technologies, waste and environmental/social problems in the agricultural/food sectors are estimated to cost the nation at least $150 billion per year. Most of the waste and environmental/social problems can be eliminated through better resource management policies and the adoption of sustainable agricultural practices.

    Ecological dimensions of Appalachian agricultural diversity, 1880–1910 (1990)

    Notes: Abstract This research uses aggregate statistical sources to describe agricultural diversity in a 31 county area of Appalachian Kentucky over the period 1880–1910. In particular, it considers the distribution and duration of forest farming in this region. It examines the causes of agricultural diversity by testing a series of hypotheses conceptually based in ecological theory. For 1880, counties differed in the degree to which they had the characteristics expected for forest farming. This variation was geographically patterned. While there was still geographical variation in county agricultural characteristics in 1910, sufficient change had occurred so that none of the counties continued to closely conform to the pattern expected for forest farming. Variation and change in county agricultural characteristics were found to be related to population density and growth, soil quality, the presence of railroads, and the development of commercial coal mining.
