    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.

    Notes: Abstract The ongoing drought in the Sahel region of West Africa highlights the vulnerability of food-producing systems to climate change and variability. Adaptation to climate should therefore increase the sustainability of agriculture under a long-term drought. Progress towards sustainability and adaptation in the the Senegal River Basin is hampered by an existing set of social and ecological relationships that define the control over the means of production and how people interact with their environment. These relationships are sensitive to the technological inputs and the administration of food production, or the factor bias in the different policy alternatives for rural development. One option is based on state-controlled, irrigated plantations to provide rice (Oryza) for the capital, Dakar. This policy emphasizes a top-down management approach, mechanized agriculture and a reliance on external inputs which strengthens the relationships introduced during the colonial period. A time series decomposition of the annual flow in the Senegal River at Bakel in Senegal suggests that water resources availability has been substantially curtailed since 1960, and a review of the water resources budget or availability in the basin suggests that this policy's food production system is not sustainable under the current climate of the basin. Under these conditions, this program is exacerbating existing problems of landscape degradation and desertification, which increases rural poverty. A natural resource management policy offers two adaptation strategies that favour decentralized management and a reduction of external inputs. The first alternative, “Les Perimetres Irrigués”, emphasizes village-scale irrigation, low water consumption cereal crops and traditional socio-political structures. The second alternative emphasizes farm-level irrigation and agro-forestry projects to redress the primary effects of desertification. The water requirements of both the rice import substitution program and the natural resource management program are calculated. A water resources simulation model/optimization analysis using dynamic programming is used to compare these two alternatives to the rice import substitution programs. Results indicate that the natural resource management policy could potentially bring a large area into production while using far less water than the rice import substitution program. The natural resource management policy, in particular the second alternative with its emphasis on individual ownership and ecological rehabiliation, defines a different set of social and ecological relationships that appear to enhance the sustainability of food production under a long-term drought.

    Keywords: adaptation ; Africa ; agriculture ; climate change ; vulnerability ; water
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering , Geography
    Notes: Abstract The intersection of present vulnerability and the prospect of climate change in Africa warrants proactive action now to reduce the risk of large-scale, adverse impacts. The process of planning adaptive strategies requires a systematic evaluation of priorities and constraints, and the involvement of stakeholders. An overview of climate change in Africa and case studies of impacts for agriculture and water underlie discussion of a typology of adaptive responses that may be most effective for different stakeholders. The most effective strategies are likely to be to reduce present vulnerability and to enhance a broad spectrum of capacity in responding to environmental, resource and economic perturbations. In some cases, such as design of water systems, an added risk factor should be considered.

    Notes: Abstract The influence of the cultivated plant stand, subject to the timing of sampling, on the occurrence of selected carabid species is investigated for three years running. Due to the nominal character of the factors (cultivar, timing, carabid species and year) we used log-linear models of four dimensional contingency tables under certain hypotheses of independence. A coefficient of contingency is calculated for characterizing the partial association between two factors respectively. The difference in G 2 's between two nested models is used to test if there are differences between the three years concerning the strength of partial association between the number of beetles in the selected species and the cultivar or the sampling time respectively.

    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 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.
