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 paper presents the initial data analyses of the CCAFS gender survey implemented in four sites in Africa. Using descriptive statistics we show gender differences in terms of perceptions of climate change, awareness and adoption of climate smart agricultural (CSA) practices, and types and sources of agro-climatic information in the four sites.We find that both men and women are experiencing changes in long-run weather patterns and that they are changing their behaviours in response; albeit relatively minor shifts in existing agricultural practices.

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.

The papers in this proceedings provide a cross section of science research in international agricultural research centres (IARCs), where the objectives and research foci within the Consultative Group on International Agricultural Research (CGIAR) have changed substantially in the 1990s. The book is divided in five sections. The first explores priority setting and research evaluation of commodity programmes. The second looks at institutional issues. The third explores issues related to commodity policies and food security.

Commune agro-ecosystems analysis (CAEA) is a participatory approach designed to help communities improve decision making at the commune (subdistrict) level. To better integrate fisheries considerations into the CAEA process, the CGIAR Challenge Program on Water and Food (CPWF) initiated the project that significantly improved the way fisheries issues are addressed. The use of CAEA has been officially adopted as a national policy for agricultural development.

The thesis explores the extent to which payment for the ecosystem service of carbon sequestration

provided in a value chain context, through an innovative climate change mitigation and adaptation

strategy known as 'carbon insetting', could generate 'win-win' outcomes for all actors.

Drawing on examples of where the concept of carbon insetting has been adopted in coffee and cocoa value chains in Mexico and Honduras respectively, the thesis investigated the feasibility of

Over the last 12 years a data base of climate, soils and crop distribution has been assembled for Latin America. Recently, socio-economic variables such as access and populations density and environmental variables such as the location of national parks, biological reserves and indian reserves have been added. Formerly this information was used primarily to make decisions on commodity research.

Most cities in developing countries fail to treat their wastewater comprehensively. Consequently, farmers downstream use poor-quality water for irrigation. This practice implies risks for farmers, consumers and the environment. Conversely, this water supply supports the livelihood of these farmers and other stakeholders along the value chains. Linking safer options for wastewater management with irrigation could therefore be a win–win solution: removing the risks for society and maintaining the bene ts for farmers.

Relying entirely on survey information and personal exchanges with over 70 scientists from within the CGIAR network, this working paper attempts to achieve a better understanding of the scope of social learning related efforts undertaken in CGIAR and main issues of relevance to more current efforts, such as that planned by the CGIAR program on Climate Change Agriculture and Food Security (CCAFS). A wide range of methods was identified, where groups of people learn in order to jointly arrive at solutions to pressing food security problems.

This report reflects the summary of baseline findings in Malawi, under the auspices of the Global Framework for Climate Services (GFCS) Adaptation Programme in Africa. It identifies gaps in climate information access and use at the local level, types of climate services farmers and pastoralists need in Malawi, relevant channels to reach farmers with requested services, lead-time and gender-specific requirements for the design and delivery of climate services that matter to farmers.
