Agricultural activities in the developing world directly contribute about 4.23 GtCO2eq/y to the current anthropogenic forcing of the global climate, and indirectly a further approximately 3.93GtCO2eq/y through forest clearing and degradation. Together they constitute a quarter of the total global climate forcing from all sources. Many proven agricultural practices and policies can reduce this impact on the global climate without compromising food production, or reduce the climate impact per unit of agricultural production.

The Asia, Pacific and Oceania (APO) region is the centre of diversity of many important species of crops, animals and livestock. Most of its resource-poor farmers depend on this agrobiodiversity for food security and livelihood. Agrobiodiversity in APO has served as the source of genetic materials that propelled the Green Revolution in the region. It has enabled continuous growth in productivity, allowing agriculture to cope with declining yield, emergence of pests and diseases and occurrence of abiotic stresses like drought and floods.

The way we produce food must adapt to a variable and changing climate. And key to achieving this is to improve the link between climate information and agricultural practices, especially those of smallholder farmers in developing countries. ‘Agro-climate tools’ do just that and some are introduced here.

Agroforestry and other tree-based systems (wood lots, afforestation) can contribute to Reducing Emissions from Deforestation and Forest Degradation (REDD+) in two ways: 1) as part of REDD+ under certain forest definitions; and / or 2) as part of a strategy for achieving REDD+ in landscapes. In the context of REDD+, agroforestry has the potential for reducing degradation by supplying timber and fuelwood that would otherwise be sourced from adjacent or distant forests.

Rhamphicarpa fistulosa is a facultative hemi-parasitic plant of the Orobanchaceae family, adapted to wet soils. Apart from tropical Australia, it is only found in sub-Saharan Africa, where it is considered a minor weed in cereal crops such as rice. Due to this status, the species has received only sporadic attention. Recent field observations and encounters with rice farmers in several African countries showed that R. fistulosa is, however, a more serious and increasing production constraint than previously thought.

The agricultural development project ACCESO

reduced greenhouse gas emissions (GHG) and

led to net carbon sequestration due to perennial

crop expansion.

? Increased fertilizer use was a moderate source

of emissions that was more than offset by

reduced emissions from other ACCESOsupported

practices, including improvements in

soil, water, and fertilizer management, and in

feed and grassland use by dairy cows.

? Compared to conventional practices, ACCESOsupported

activities reduced emission intensity

This working paper synthesizes knowledge within CGIAR on adaptation measures in agricultural systems, for the benefit of parties and observers preparing submissions to the UNFCCC SBSTA. Experience from CGIAR and partners indicate that adaptation measures covering policy, technological, financial, institutional, and research interventions are being tested and applied in agricultural systems in low-income and middle-income countries.
