Agriculture – on which we all depend for our food – is under threat from climate change. There is no doubt that systems worldwide will have to adapt, but while consumers may barely notice in developed countries, millions of people in developing countries face a very real and direct threat to their food security and livelihoods. Even without climate change, many agricultural systems in developing countries are nearing crisis point. Feeding a rapidly rising global population is taking a heavy toll on farmlands, rangelands, fisheries and forests. Water is becoming scarce in many regions.

In East Africa, agricultural systems are highly vulnerable to climate change and variability because of high dependence on rainfall. The increasing frequency and severity of drought, heat and cold stress as well as floods are likely to lead to major food crises in the region. Rapid population growth rates, poverty and inequality exacerbate problems caused by exposure to climatic change. The region, therefore, requires long-term actions to build the capacity of its people and institutions to better adapt to climate change and climate variability, and reduce greenhouse gas emissions.

With more than 60 percent of Asian population either directly or indirectly relying on agriculture for livelihood, agriculture remains key to uplifting lives of many people in the region, as well as to providing sufficient and nutritious food for all.

In Asia, CIAT undertakes scientific research enabling smallholder farmers, agri-food businesses, and national governments to use smart technologies and innovations and make evidence-based decisions, towards achieving profitability, environmental sustainability and resiliency in agriculture.

At independence in 1960, Africa was a modest food exporter while Asia was engulfed in a food crisis. The Green Revolution boosted food production in Asia and the global food problem shifted to Africa. However, science and technology have been promoted on an ad hoc basis in Africa's 45 years of independence. This chapter analyses why the Asian Green Revolution failed to take root in Africa, and why the average African grain yield has been flat since 1960.

There is limited documentation of soil and water management technologies that enhance adaptation to climate change in drylands of Kenya. Rainfall patterns were analyzed in the semi-arid Machakos and Makueni counties of eastern Kenya using historical data. A total of forty-three smallholder farmers implementing soil water management practices were sampled, and an estimate of the seasonal water budget for current crop and livestock production systems computed.

This document series compiles key indicators from the three levels of the baseline for each site. Indicators include: demography and basic site characteristics of each site, rainfall distribution, changes in farming practices and land management, income sources, food security and food

sources, asset ownership by households and involvement in organisations and more. This CCAFS baseline indicator document was developed for the CCAFS site at Borana/Yabero, in Ethiopia.

The University of Aberdeen and CCAFS are developing a simple tool for practitioners to quickly identify and compare mitigation options for agriculture. The CCAFS-MOT tool takes account of current farming practices and growing conditions to suggest a wide range of

mitigation options. The Excel-based tool is free and downloadable from the CCAFS website.

Summary Report from the workshop held in Rome 27-28 October 2011

Up to 75% of deforestation in Brazil is associated with cattle ranching. To reduce forest conversion and increase sustainability in the cattle supply chain, government, private sector and civil society support interventions based on combinations of institutions and policies, incentives, and information and technology. In this paper we analyse the observed and expected interactions among the Sustainable Agriculture Network (SAN) Standard for Sustainable Cattle Production Systems certification program and other interventions associated with livestock and deforestation in Amazonia.
