Maize-Rice Cropping Systems in Bangladesh: Status and Research Opportunities AgEcon
Ali, M. Yusuf; Waddington, Stephen R.; Hodson, Dave P.; Timsina, J.; Dixon, John.
Responding to demand from expanding poultry feed markets, maize area in Bangladesh rose from only a few thousand hectares in the 1980s to more than 200,000 hectares in 2007-08. This publication describes the rise of maize in Bangladesh, emerging problems or risks, technology options for rice-maize systems, and future research and development needs. It also outlines the role of CIMMYT, through its Bangladesh office, in the establishment and promotion of maize, as well as the provision of germplasm and capacity building for researchers and farmers, in collaboration with the Bangladesh Agricultural Research Institute (BARI), the Department of Agricultural Extension (DAE), and diverse non-governmental organizations.

Farmers' Taxonomies as a Participatory Diagnostic Tool: Soil Fertility Management in Chihota, Zimbabwe AgEcon
Bellon, Mauricio R.; Gambara, Peter; Gatsi, Tendai; MacHemedze, Timothy E.; Maminimini, Obert; Waddington, Stephen R..
Soil infertility is a major constraint to food production in the communal areas of Zimbabwe. Smallholders in the region recognize the problems of low soil fertility and have devised ways of coping with them. This study describes the use of farmers’ taxonomies of themselves and their soils to identify and understand the options they have, and the constraints they face in managing poor soil fertility in Chihota, a sub-humid communal area of north central Zimbabwe. It is part of an effort by a group of agricultural researchers and extensionists working on improved soil fertility technologies, to better integrate their work with farmers in order to expose the latter to promising technologies, get feedback on the technologies merits and feasibility, and help...

Breaking the "Fertilizer Poverty" and Food Insecurity Traps in Smallholder Maize Based Farming System in Southern Africa: Experiences and Lessons from Soil Fertility Network/Economics and Policy Working Group (EPWG) AgEcon
Mekuria, Mulugetta; Waddington, Stephen R.; Siziba, Shephard.
Smallholder farmers in southern Africa face acute food insecurity because the productive capacity of their soils has declined. These resource-poor farmers increasingly cannot afford mineral fertilizers Farmers mentioned the lack of fertilizers for their depleted soils as the most important constraint- "Empty Soils, stomachs and pockets." In response to this challenge, Soil Fert Net researchers in southern Africa have developed and promoted a range of "best-bet" soil fertility management technological (SFMT) options for farmers. This paper presents a review of financial, adoption, institutional and policy analysis undertaken by EPWG members on the use of SFMT by smallholders. Financial and risk analysis tools, selected econometric models and policy analysis...
