Assessing options for crop-livestock intensification in semi-arid Southern Zimbabwe: household typologies and community visions
Presentation of Assessing options for crop-livestock intensification in semi-arid Southern Zimbabwe: household typologies and community visions
Can African smallholders farm themselves out of poverty?
A great deal of research on agriculture in Africa is organised around the premise that intensification can take smallholder farmers out of poverty. The emphasis in programming often implicitly emphasizes focusing on farm ...
What Kind of Research and Development is Needed for Natural Resource Management?
This paper presents a set of principles and operational guidelines for research and
development (R&D) to better address natural resource management problems distilled in a series of workshops
with more than 150 experts and ...
Influence of putative forest refugia and biogeographic barriers on the level and distribution of genetic variation in an African savannah tree, Khaya senegalensis (Desr.) A. Juss
Phylogeographic studies of tropical and subtropical
tree species provide an ideal method to study the role of forest
refugia in the structuring of genetic diversity in contemporary
populations. To date, most studies have ...
OPINION: As drought hits, Zimbabweans are going hungry
Efforts to boost food security, health and nutrition in Zimbabwe's cities could have a big payoff
Assessing the potential of dual-purpose maize in southern Africa: A multi-level approach
This paper explores the potential and challenges of increasing production of food and feed on existing maize fields in mixed crop-livestock systems in the semi-arid areas of southern Africa. It integrates results from ...
Diet crisis in Africa’s low income urban zones but transition to nutritious foods possible
CGIAR, the world’s largest global agricultural research network, has traditionally focused on rural areas. But now cities are attracting its gaze.
There are two compelling reasons for this shift. First, urban dwellers in ...
Maize–mucuna rotation: An alternative technology to improve water productivity in smallholder farming systems
Rain-fed crop production systems in the semi-arid tropics of Zimbabwe are characterized by low water productivity (WP), which is partly attributed to inherent low soil fertility, and further exacerbated by continuous ...
Spatial Variation in Tree Density and Estimated Aboveground Carbon Stocks in Southern Africa
Variability in woody plant species, vegetation assemblages and anthropogenic activities derails the efforts to have common approaches for estimating biomass and carbon stocks in Africa. In order to suggest management ...
Length of Growing Period over Africa: Variability and Trends from 30 Years of NDVI Time Series
The spatial distribution of crops and farming systems in Africa is determined by the duration of the period during which crop and livestock water requirements are met. The length of growing period (LGP) is normally assessed ...
