As the population continues to grow and natural resources become scarcer, the need to shift toward an environmen­tally responsible, socially accountable, more equitable, and “greener” economy has become increasingly apparent. Despite differing perspectives and definitions among stakeholders, the “green economy” is often seen as an economy that pursues growth while also promoting sustainable development through more efficient use of resources.

We investigate the impacts of sustainable land management practices on soil carbon stocks and also impacts of soil carbon on the mean and variance of crop production using econometric tools. Using a cross-sectional plot-level dataset collected from three agroecological zones of Uganda with soil carbon measured at a depth of 0 to 15 centimeters, our results have robustly shown that irrigation, fertilizers, improved fallow, crop residues, mulching, and trash lines are positively and significantly associated with higher soil carbon, corroborating results from agronomic experiments.

Facilitating carbon sequestration in terrestrial ecosystems could provide a significant amount of atmospheric carbon dioxide (CO2) abatement, which is necessary to limit global temperature increases to only 2 degrees Celsius in the next century until more permanent mitigation strategies are instituted.

Human activities such as fossil fuel burning and deforestation have significantly increased the atmospheric concentration of greenhouse gases (GHG) leading to global climate change. Global climate change and its associated weather extremes pose considerable challenges worldwide, and mitigating the adverse impacts of climate change is a high priority for the international community. To reduce global emissions and curb the threat of climate change, many countries are participating in carbon trading.

Desde 2007, se produjeron dos rondas de picos de los precios de los alimentos que han contribuido a que al hambre y la malnutrición de millones de personas.

This policy note summarizes the findings of two literature reviews on the gender-differentiated impacts of climate change and the scope for community-based adaptation. It also outlines the framework used to guide these analyses and the other papers summarized in this series.

Approximately 80 percent of poor people in Sub-Saharan Africa continue to depend on the agricultural sector for their livelihoods, but-unlike in other regions of the world-agriculture in Sub-Saharan Africa is characterized by very low yields due to agroecological features, poor access to services, lack of knowledge and inputs, and low levels of investment in infrastructure and irrigation. In addition, high population growth rates, especially in rural areas, intensify pressure on agricultural production and natural resources and further complicate the challenge of reducing poverty.

Sub-Saharan Africa (SSA) faces great challenges in development, including the highest poverty rate in the world, food insecurity, and malnutrition. Given that agriculture is the single most important source of rural livelihood in Africa, an agricultural growth strategy will go a long way to reducing hunger and poverty on the subcontinent. Among the numerous challenges to enhancing agricultural production in SSA is the large spatial and temporal variability and availability of water resources. Currently, agriculture in SSA is predominantly rainfed.

Global climate change poses great risks to poor people whose livelihoods depend directly on agriculture, forestry, and other natural resource uses. IFPRI's climate change research focuses on the assessment of, adaptation to, and mitigation of these risks. Strategic, cost-effective, and pro-poor policy reforms that enhance human welfare in equitable and sustainable ways form the core ofIFPRI's Global Change Program. The Program analyzes the complex interrelations between climate change and agricultural growth, food security, and natural resource sustainability.

This report is timely input into the ongoing development agenda for Africa South of the Sahara (SSA).
