Simulation analysis of factors affecting sorghum yield at selected sites in eastern and southern Africa, with emphasis on increasing temperatures
Global warming is widely predicted to decrease crop yields in tropical, sub-tropical and Mediterranean
climatic regions as a result of a speeding up of phenological development and shortening of the time
to maturity. We ...
Exploring the challenges with soil data in regional land use analysis
Over recent decades, environmentalmodels have gradually replaced traditional, qualitative land evaluation in regional
land use analysis (RLUA). This changed the data requirements as the environmental models require ...
Biomass in crop-livestock systems in the context of the livestock revolution
Mixed crop-livestock systems are the dominant source of livelihood supporting more
than 80% of people living in the developing world and producing 50% of world
cereals, around 34% of the global beef production and about ...
Edifice growth and collapse of the Pliocene Mt. Kenya: Evidence of large scale debris avalanches on a high altitude glaciated volcano
The cyclic growth and destruction of the Late Cenozoic Stratovolcano Mt. Kenya have been reconstructed for its
southeastern segment. At least three major debris avalanche deposits have been reconstructed and dated. The
oldest ...
Maize productivity and profitability in Conservation Agriculture systems across agro-ecological regions in Zimbabwe: A review of knowledge and practice
Conservation agriculture (CA) is increasingly promoted in southern Africa as a strategy to improve food
security and reverse soil degradation in the face of climate change. However, the performance of CA
under different ...
Is rainfed agriculture really a pathway from poverty?
Agriculture’s potential to reduce poverty at household level is explored for rainfed crop production in
Africa and India. A literature survey of crop improvement and natural resource management interventions
demonstrates ...
Are there “women’s crops”? A new tool for gender and agriculture
A “Gender Control Tool” was developed to measure women’s control over
decision-making for agricultural production, sales, and use of income. The
tool was tested for groundnuts in Eastern Province, Zambia, where
mechanisation ...
Innovation platforms for sustainable land management in East African landscapes: Stewardship, incentives, and challenges
This paper examines the potential role of innovation platforms (IPs) in facilitating the adoption and scaling up of Sustainable Land
Management (SLM) practices in East Africa, where land degradation has been a prime challenge ...
The impact of tillage system and herbicides on weed density, diversity and yield of cotton (Gossipium hirsutum L.) and maize (Zea mays L.) under the smallholder sector
The study was carried out to evaluate the impact of tillage system in combination with different herbicides
on weed density, diversity, crop growth and yields on 18 farms in Kadoma, Zimbabwe. Experiments
were set up as a ...
Integrated crop-livestock systems − a key to sustainable intensification in Africa
Mixed crop-livestock systems provide livelihoods for a billion people and produce half the world’s cereal and around a third of its beef and milk. Market orientation and strong and growing demand for food provide powerful ...
