Potential technology and research needs for rainfed maize production in drought prone environments of Southern Africa
In southern Africa, semi-arid areas (here simply defined as areas with less than 700 mm but more than 350 mm of rainfall per annum) can be found from around 100 m to over 1,400 m above sea level. The semi-arid areas most ...
Maize adaptive research: achievements and prospects in Southern Africa
In the last six to eight years, farming systems adaptive research has contributed much to the understanding of maize production constraints on smallholder farms in southern Africa. It has contributed less to the development ...
Targeting recommendations for small farmers: the role of economic factors in Zimbabwe and Swaziland
Natural conditions and major resource differences such as farm size are commonly used in on-farm research to define homogeneous 'recommendation domains' within which new technologies are tested. Successful trial results ...
The contribution of economic analysis in developing promising research agendas: a maize nitrogen x phosphorus trial in Zimbabwe
Maize accounts for 70% of Zimbabwe's cereal growing area. Its productivity, particularly in the communal areas, is limited by both soil and moisture constraints. Most soils in communal areas are coarse-textured sands derived ...
Chimanga cha makolo, hybrids and composites: farmers' adoption of maize technology in Malawi, 1989-90
During the 1989-90 and 1990-91 cropping seasons, researchers from CIMMYT and the Evaluation Units of the Malawian Ministry of Agriculture (MOA) collected data to profile farmers' adoption behavior and varietal choices, and ...
Reconstituting family transitions of Sahelian western Niger 1950-2000: an agent-based modelling approach in a low data context
(Cybergeo : European Journal of Geography, 2013)
This research analyses the impacts of the family organization on the diversity of income sources and the sustainability and the dynamics of rainfed farming systems of Sahelian Niger, through an individual-centred agent-based ...
Comparative economics of maize production in risky environments in Zimbabwe
Planting strategies of smallholder farmers are examined in two contrasting study areas in Zimbabwe, Mangwende (sub-humid, natural region II) and Mudzi (semi-arid, natural region IV). to show that farmers regard maize as a ...
Effect of climate change on spring wheat yields in North America and Eurasia in 1981-2015 and implications for breeding
(Public Library of Science, 2018)
Wheat yield dynamic in Canada, USA, Russia and Kazakhstan from 1981 till 2015 was related to air temperature and precipitation during wheat season to evaluate the effects of climate change. The study used yield data from ...
Addressing conflict through collective action in natural resource management
(Utrecht University Library Open Access Journals; International Association for the Study of the Commons, 2017)
The food security crisis and international “land grabs” have drawn renewed attention to the role of natural resource competition in the livelihoods of the rural poor. While significant empirical research has focused on ...
Who is quitting? An analysis of the dis-adoption of climate smart sorghum varieties in Tanzania
(Emerald Publishing Limited, 2019)
Purpose: New agricultural technologies are continuously generated and promoted for adoption by farmers with the expectation that they bring about higher benefits than older technologies. Yet, depending on the perceived ...
