This working paper represents work‐in‐progress of the CBFC project (Community‐based Fish Culture in Seasonal Floodplains and Irrigation Systems), a research project supported by the Challenge Program on Water and Food (CPWF), with the aim of increasing productivity of seasonally occurring water bodies through aquaculture.The project has been implemented in Bangladesh, Cambodia, China, Mali and Vietnam, where technical and institutional options for community based aquaculture have been tested. The project began in 2005 and was completed in March 2010.
The purpose of this issues paper is to provide an overview of the issues, numbers, disputes, and approaches so that contributors to SOW11 can share a common framework and consider how the innovations they describe fit into the larger international discourse. The paper is structured as follows: • Section 2 describes diverse perspectives on food security that emphasize global supply chains to feed middle-class populations in cities; smallholder farmers who still supply much of the world; and smallholder farmers who are relatively disengaged in commercial markets.
Livelihoods, food security, and development processes in Sub-Saharan Africa are highly dependent on land management practices to generate natural ecosystem goods and services. Out of a total population of about 717 million people, almost 60 percent depend for their livelihood on agriculture, hunting, fishing, or forestry. However, unsustainable land management already is leading to large-scale land degradation trends, which pose a threat to food security and poverty alleviation in Sub-Saharan Africa. Climate change threatens to exacerbate and add to the existing vulnerabilities.
The World Bank has a long relationship with Uruguay's agricultural sector, expanding over a period of more than 60 years in which several projects and various analytical and advisory assistance initiatives have been implemented.
This report presents the impact and lessons learned from the Andhra Pradesh Drought Adaptation Initiative (APDAI). The APDAI was implemented as a package of pilot activities in two dryland districts in Andhra Pradesh (Anantapur and Mahbubnagar) with the aim of developing and testing approaches for natural resource-based economic activities to better respond to current climate variability and long-term consequences of climate change. The report discusses how innovations are being scaled up through integration into regular government programs for greater outreach.
African farming systems are highly heterogeneous: between agroecological and socioeconomic environments, in the wide variability in farmers’ resource endowments and in farm management. This means that single solutions (or ‘silver bullets’) for improving farm productivity do not exist. Yet to date few approaches to understand constraints and explore options for change have tackled the bewildering complexity of African farming systems. In this paper we describe the Nutrient Use in Animal and Cropping systems – Efficiencies and Scales (NUANCES) framework.
Participatory varietal selection (PVS) is a recent approach increasingly being used in developing countries to make the farmers choose the best suited variety for their locality. Sugarcane Breeding Institute, Coimbatore implemented this participatory approach in M.R.K. Cooperative Sugar Mills Ltd., Sethiathope, Tamil Nadu during 2002 to 2006. Participatory rural appraisal and agro-eco system analysis were done with the participation of farmers to assess the situation and identify the needs of sugarcane growers.
Agroforestry (AF) systems have been the focus of numerous research and development projects in southern Africa, yet their adoption rate generally remains low. Employing on-farm, participatory research techniques in southern Malawi, was compared the suitability of three AF-based systems that relay crop the dominant staple, maize (Zea mays), with the perennial legumes Sesbania sesban, Tephrosia vogelii, and Cajanus cajan (pigeonpea).
Digital Agriculture is an “intelligent” computer management and application system that includes many high technologies of, such as infomationization, digitization, network, automation and more so on. On the basis of analyzing the main content and meaning of “Digital Agriculture”, this paper designs the system construction of “Digital Agriculture” based on Internet, and discusses the function and structure of main core modules of System of Digital Agriculture in detail. Finally, this paper also analyzes the developing trend about system of “Digital Agriculture”
