"Growing consensus in the scientific community indicates that higher temperatures and changing precipitation levels resulting from climate change will depress crop yields in many countries over the coming decades. This is particularly true in low-income countries, where adaptive capacity is low....

The major roots and tubers—cassava, potato, sweet potato, and yam—play a significant role in the global food system.They contribute to the energy and nutrition requirements of more than 2 billion people in developing countries and will continue to do so over the next two decades. They are...

"With increasing competition for water across sectors and regions, the river basin has been recognized as the appropriate unit of analysis for addressing the challenges of water resources management. Modeling at this scale can provide essential information for policymakers in their resource...

"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...

"Global climate change poses great risks to poor people whose livelihoods depend directly on the use of natural resources. Mitigation of the adverse effects of climate change is a high priority on the international agenda. Carbon trading, under the Kyoto Protocol as well as outside the protocol,...

"This paper investigates the impact of climate variability on maize yield in the Limpopo Basin of South Africa using the Generalized Maximum Entropy (GME) estimator and Maximum Entropy Leuven Estimator (MELE). Precipitation and temperature were used as proxies for climate variability, which were...

"This paper presents an empirical analysis of the impact of climate change on food production in a typical low-income developing country. Furthermore, it provides an estimation of the determinants of adaptation to climate change and the implications of these strategies on farm productivity. The...

"Water management in the Pirapama River Basin in northeastern Brazil is affected by both water quantity and water quality constraints. The region is known for significant sugarcane-based ethanol production—which is key to the Brazilian economy and expected to grow dramatically under recent...

"This study identifies the major methods used by farmers to adapt to climate change in the Nile Basin of Ethiopia, the factors that affect their choice of method, and the barriers to adaptation. The methods identified include use of different crop varieties, tree planting, soil conservation,...

La gran importancia de las raices y tuberculos como fuente de ingresos para los agricultores pobres y como fuente de alimento para la poblacion de escasos recursos, tanto rural como urbana, es muchas veces ignorada en el debate sobre el mejoramiento de la seguridad alimentaria y la erradicacion...
