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 ...
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 ...
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 ...
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 ...
Co-designing the transitions towards integrated market oriented mixed farming systems in semi-arid Zimbabwe
poverty trap. These barriers include low soil fertility, variable climates, weak knowledge support, and lack of markets. Conventional technical options are insufficient to improve smallholder livelihoods. Given the diversity ...
Economic trade-offs of biomass use in crop-livestock systems: Exploring more sustainable options in semi-arid Zimbabwe
In complex mixed crop-livestock systems with limited resources and biomass scarcity, crop residues play an important but increasingly contested role. This paper focuses on farming systems in the semi-arid areas of Zimbabwe, ...
Crop–Livestock Intensification in the Face of Climate Change: Exploring Opportunities to Reduce Risk and Increase Resilience in Southern Africa by Using an Integrated Multi-modeling Approach
The climate of Southern Africa is highly variable at most time-scales and follows a pronounced gradient with arid conditions in the west and humid conditions in the east. There is also a marked latitudinal rainfall ...
Assisting smallholder farmers in mixed crop-livestock systems to understand the potential effects of technologies and climate change through participatory modeling
Smallholder farming systems in the semiarid
areas of Zimbabwe are characterized by low production. This low production is not solely
due to lack of technologies but also due to a lack of integrating a diversity of viewpoints ...
Re-designing smallholder farming futures for reduced vulnerability to climate change in semi-arid southern Africa
Climate change will impact the productivity of maize-based crop-livestock systems and the food security of smallholders depending on them in semi-arid southern Africa. Earlier results from testing climate change adaptation ...
