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 ...
Learning about sustainability and gender through Farmer Field Schools in the Taita Hills, Kenya
This research uses transformative learning theory to explore how Farmers Field Schools (FFS) of the Taita
Hills, Kenya have contributed to environmental sustainability, with a particular focus on gendered
learning. Both ...
Evidence that dicot-infecting mastreviruses arep articularly prone to inter-species recombination and have likely been circulating in Australia for longer than in Africa and the Middle East
Viruses of the genus Mastrevirus (family Geminiviridae) are transmitted by leafhoppers and infect either mono- or dicotyledonous plants. Here we have determined the full length sequences of 49 dicot-infecting mastrevirus ...
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 ...
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 ...
Designing index based livestock insurance for managing asset risk in northern Kenya
This article describes a novel indexbased
livestock insurance (IBLI) product piloted among pastoralists in
Northern Kenya, where insurance markets are effectively absent and uninsured risk exposure is a main
cause of ...
Do faba bean (Vicia faba L.) accessions from environments with contrasting seasonal moisture availabilities differ in stomatal characteristics and related traits?
Drought is a major constraint to faba bean (Vicia faba L.) production, and there are many mechanisms by which leaves can regulate water loss. Our primary objective was to test if the origin of the faba bean accessions, ...
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 ...
Pastoralism and ecosystem-based adaptation in Kenyan Masailand
Purpose – The purpose of this paper is to assess the potential for pastoral communities inhabiting. Kenyan Masailand to adapt to climate change using conservancies and payments for ecosystem services. Design/methodology/approach ...
