South Asian countries face mounting challenges in meeting the growing demand for food, water, and energy for a rapidly growing population. Countries have provided policy support to increase cereal production, including providing incentives by subsidizing water and energy and guaranteeing rice and wheat prices.
Global Climate Change (CC) resulting from an increasing concentration of Greenhouse Gases (GHGs) in the atmosphere has become an accepted and major theme in today‘s world. According to the Intergovernmental Panel on Climate Change (IPCC), the average temperature of the earth increased by 0.6 ° C over the last century and it is expected to further increase by 1.4 to 5.8 º C by the end of the current century. These changes in temperature are but the crest of the many environmental, social and political issues which will follow in the wake of the changing climate. Unfortunately the major causes of a rapidly warming climate can be attributed to anthropogenic activities such as the burning of fuel, the depletion of forests and changes in land use (conversion of forest into agriculture land).
Although much has been written about climate change and poverty as distinct and complex problems, the link between them has received little attention. Understanding this link is vital for the formulation of effective policy responses to climate change. This paper focuses on agriculture as a primary means by which the impacts of climate change are transmitted to the poor, and as a sector at the forefront of climate change mitigation efforts in developing countries. In so doing, the paper offers some important insights that may help shape future policies as well as ongoing research in this area.
Are global temperatures on a warming trend? It is di¢ cult to be certain about trends when there is so much variation in the data and very high correlation from year to year. We investigate the question using statistical time series methods. Our analysis shows that the upward movement over the last 130-160 years is persistent and not explained by the high correlation, so it is best described as a trend. The warming trend becomes steeper after the mid-1970s, but there is no signi cant evidence for a break in trend in the late 1990s. Viewed from the perspective of 30 or 50 years ago, the temperatures recorded in most of the last decade lie above the con dence band of forecasts produced by a model that does not allow for a warming trend.
What are the major determinants of green growth? What role can the government play to promote green growth? To address these questions, this paper develops a simple Green Solow model that sheds light on the role of finance and technology in the process of green growth. The empirical section of the article augments this canonical green growth model to include structural variables relating to finance, technological development, trade openness, natural resource exploitations, and areas where the government can play an important role. In addition, the use of the spatially-corrected generalized method moments approach affords us to explore the role of such factors as growth performance of the neighboring countries, domestic learning or determination to achieve its national desired target, and political and economic shocks in the process of green growth. It is hoped that research reported in the paper will stimulate further research in the area.
This study analyzes the vulnerability of Ethiopian farmers to climate change based on the integrated vulnerability assessment approach using vulnerability indicators. The vulnerability indicators consist of the different socioeconomic and biophysical attributes of Ethiopia’s seven agriculture-based regional states. The different socioeconomic and biophysical indicators of each region collected have been classified into three classes, based on the Intergovernmental Panel on Climate Change’s (IPCC 2001) definition of vulnerability, which consists of adaptive capacity, sensitivity, and exposure. The results indicate that the relatively least-developed, semiarid, and arid regions—namely, Afar and Somali—are highly vulnerable to climate change. The Oromia region—a wide region characterized both by areas of good agricultural production in the highlands and midlands and by recurrent droughts, especially in the lowlands—is also vulnerable. The Tigray region, which is characterized by recurrent drought, is also vulnerable to the negative impacts of climate change in comparison with the other regions. Thus, investing in the development of the relatively underdeveloped regions of Somali and Afar, irrigation for regions with high potential, early warning systems to help farmers better cope in times of drought, and production of drought-tolerant varieties of crops and species of livestock can all reduce the vulnerability of Ethiopian farmers to climate change.
Climate change will have severe impacts in many parts of the tropics and subtropics. Despite the importance of livestock to poor people and the magnitude of the changes that are likely to befall livestock systems, the intersection of climate change and livestock is a relatively neglected research area. Little is known about the interactions of climate and increasing climate variability with other drivers of change in livestock systems and in broader development trends. Evidence is being assembled that the temporal and spatial heterogeneity of household responses may be very large. While opportunities may exist for some households to take advantage of more conducive rangeland and cropping conditions, for example, the changes projected will pose very serious problems for many other households. Furthermore, ruminant livestock themselves have important impacts on climate, through the emission of methane and through the land-use change that may be brought about by livestock keepers.
This series presents eight guidance notes (GN1 - GN8) that provide lessons learned, best practices, recommendations, and useful resources for integrating climate risk management and adaptation to climate change in development projects, with a focus on the agriculture and natural resources management sectors. They are organized around a typical project cycle, starting from project identification, followed by project preparation, implementation, monitoring and evaluation. Each note focuses on specific technical, institutional, economic, or social aspects of adaptation.
