This paper examines the nature of community management of woodlots and investigates the determinants of collective action and its effectiveness in managing woodlots...in Tigray, northern Ethiopia. We find that collective management of woodlots generally functions well in Tigray.... The findings suggest collective action may be more beneficial and more effective when managed at a more local level, when the role of external organizations is more demand-driven, and when promoted in intermediate population density communities more remote from markets.

Climate change projections internationally accepted as being reliable indicate that most countries in the Pacific region will suffer large-scale negative impacts from climate change. These impacts are likely to include elevated air and sea-surface temperatures, increasingly unpredictable rainfall patterns, rising sea levels, and intensification of extreme weather events such as tropical cyclones and El Niño-related droughts.

La demanda de biocombustibles se está incrementando debido a la necesidad cada vez mayor de energéticos, el alza en el costo del petróleo, la búsqueda de fuentes de energía renovables y no contaminantes y el deseo de aumentar los ingresos agrícolas en los países en desarrollo. Asimismo, ha aumentado en forma drástica la necesidad de contar con cultivos, como el maíz y la caña de azúcar, que pueden utilizarse como materia prima para producir biocombustibles. Esta demanda ha tenido a nivel mundial un impacto significativo y cada vez mayor en los sistemas alimentarios.

Common-pool resource management is a critical element in the interlocked challenges of food security, nutrition, poverty reduction, and environmental sustainability. This paper examines strategic policy choices and governance challenges facing Cambodia‘s forests and fisheries, the most economically important subsectors of agriculture that rely on common-pool resources. It then outlines policy priorities for institutional development to achieve improvements in implementing these goals.

High food prices are not only causing a humanitarian crisis, but also putting at risk the development potential of millions of people. Global agriculture markets are undergoing structural changes, and the next three to four years will pose great challenges for achieving an affordable and accessible food supply for the world's most vulnerable. Soaring food and fuel prices are creating a "perfect storm" for the world's most vulnerable.

Agriculture and climate change are inextricably linked. Agriculture is part of the climate change problem, contributing about 13.5 percent of annual greenhouse gas (GHG) emissions (with forestry contributing an additional 19 percent), compared with 13.1 percent from transportation. Agriculture is, however, also part of the solution, offering promising opportunities for mitigating GHG emissions through carbon sequestration, soil and land use management, and biomass production.
