Climate change has become an issue which touches upon all spheres of life. To combat the problem, understanding the perceptions of all that have stake in it provides with stronger ground for decision-making. Ethiopia is one those countries that are or going to be severely affected by climate change, the solution of which partly depends on how its key decision-makers perceive the problem. In light of this a questionnaire survey was conducted on 195 volunteering members of the House of People’s Representatives in Ethiopia. The results of data analysis reveal that most identified rainfall variability, declining hydrology and increasing temperature as manifestations of climate change, and emission reduction and forest protection as its key solutions. 相似文献

Adoption of agricultural production technologies in developing countries is influenced by a wide range of economic and social factors as well as physical and technical aspects of farming and the risk attitude of farmers. It is important to understand the role of these factors to ensure the development of appropriate technologies and the design of successful development projects. This study examines the impact of such factors on the adoption of single-ox, fertilizer and pesticide technologies as part of a post-drought recovery project in Tegulet-Bulga district in Ethiopia. Models to evaluate the probability of adoption are specified for the respective technologies and are estimated using a logit maximum likelihood procedure, results indicate that the most significant variable affecting the probability of adoption of all three technologies is farm size; the impact is negative for single-ox technology and positive for fertilizer and pesticide use. Economic factors such as income, wealth and debt generally exhibit statistically significant influence on the adoption of single-ox and pesticide technologies as do family size, access to outside information, education and experience. The effect of socio-economic factors on adoption of fertilizer and pesticide technologies is greater in the area which has more access to outside information and off-farm activities (Ankober) than in more ‘self-contained’ area (Seladengay). The impact of the degree of risk aversion of farmers is found to be significant and negative for single-ox technology in both areas, and for fertilizer and pesticide technologies in only one area. The predicted probabilities of technology adoption by an average farmer are found to increase dramatically with the level of education and access or exposure to outside information. 相似文献

How rapidly will child malnutrition respond to income growth?This article explores that question using household survey datafrom 12 countries as well as data on malnutrition rates in across-section of countries since the 1970s. Both forms of analysisyield similar results. Increases in income at the householdand national levels imply similar rates of reduction in malnutrition.Using these estimates and better than historical income growthrates, the article finds that the Millennium Development Goalof halving the prevalence of underweight children by 2015 isunlikely to be met through income growth alone. What is neededto accelerate reductions in malnutrition is a balanced strategyof income growth and investment in more direct interventions. 相似文献
