Livestock water productivity: feed resourcing, feeding and coupled feed-water resource data bases
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
While water requirement for livestock is widely perceived as daily drinking water consumption, ~100 times more water is required for daily feed production than for drinking water. Increasing livestock water productivity can be achieved through increasing the water-use efficiency (WUE) of feed production and utilisation. The current paper briefly reviews…

Prioritizing investments for climate-smart agriculture: Lessons learned from Mali
International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)
Abstract
Agricultural productivity and growth in Mali are under threat from erratic rainfall, resulting in more frequent dry years. The national economy is vulnerable to climate change due to 50% of the gross domestic product coming from the agricultural sector and 75% of the population living in rural areas. The Climate-Smart Agriculture (CSA) concept arises from a need to…

Potential of cowpea variety mixtures to increase yield stability in subsistence agriculture: preliminary results
International Potato Center (CIP)
https://hdl.handle.net/10568/41898
Abstract
Cowpea Vigna unguiculata (L.) Walp. is an important leafy vegetable and grain legume in Uganda. Unlike in commercial agriculture, where variety mixtures are known to give higher and more stable yields, the performance of cowpea variety mixtures in subsistence agriculture is little known. Mixtures containing up to four cowpea…

https://hdl.handle.net/10568/67074
Abstract
Understanding functional relations among plant traits and their modulation by growing conditions is imperative in designing selection strategies for breeding programs. This study assessed trait relationships among 196 common bean genotypes exposed to stresses for drought and field infestation of bean fly or bean stem maggot (BSM…

The Role of Multi-Stakeholder Platforms for Creating an Enabling Climate Change Policy Environment in East Africa
World Agroforestry Centre (ICRAF)
Abstract
Research-based evidence on the adoption of climate-smart agricultural practices is vital to their effective uptake, continued use and wider diffusion. In addition, an enabling policy environment at the national and regional levels is necessary for this evidence to be used effectively. This chapter analyzes a 4-year period of continuous policy engagement in East Africa in an…

Household Welfare Effects of Stress-Tolerant Varieties in Northern Uganda
World Agroforestry Centre (ICRAF)
Abstract
This study assessed the adoption of stress-tolerant varieties and their effect on household welfare, measured by net crop income per capita in Nwoya District, Uganda. The stress-tolerant varieties were considered to be climate-smart because they stabilise and increase crop income in the presence of climatic shocks. However, the uptake of the stress-tolerant varieties was still low in northern Uganda, due to bad past…

A Participatory Approach to Assessing the Climate-Smartness of Agricultural Interventions: The Lushoto Case
World Agroforestry Centre (ICRAF)
Abstract
The concept of climate-smart agriculture (CSA) is gaining momentum across the globe. However, it is not specific on what should be covered under its three pillarsâ??productivity, resilience and mitigation. Consequently, CSA encompasses many different agricultural practices/technologies, making it difficult to prioritise CSA objectives. Firstly, there is a lack of clear and workable…

Exploring adaptation strategies of coffee production to climate change using a process-based model
World Agroforestry Centre (ICRAF)
Abstract
The response of coffee (Coffea arabica L.) agronomical performance to changes in climate and atmospheric carbon dioxide concentration ((CO2)) is uncertain. Improving our understanding of potential responses of the coffee plant to these changes while taking into consideration agricultural management is required for identifying best-bet adaptation strategies. A mechanistic crop modelling approach…

USING APSIM-MODEL AS A DECISION-SUPPORT-TOOL FOR LONG-TERM INTEGRATED-NITROGEN-MANAGEMENT AND MAIZE PRODUCTIVITY UNDER SEMI-ARID CONDITIONS IN KENYA
World Agroforestry Centre (ICRAF)
Abstract
There is continued decline in per capita agricultural productivity in the drier parts of Kenya's central highlands. The declines have been linked to low and declining soil fertility, soil water, high atmospheric heat, prolonged dry-spells and erratic rainfall. Integrated soil fertility management (ISFM) technologies have been developed and…

Mapping of soil organic carbon stocks for spatially explicit assessments of climate change mitigation potential
World Agroforestry Centre (ICRAF)
Abstract
Current methods for assessing soil organic carbon (SOC) stocks are generally not well suited for understanding variations in SOC stocks in landscapes. This is due to the tedious and time-consuming nature of the sampling methods most commonly used to collect bulk density cores, which limits repeatability across large areas, particularly where information is needed on the spatial…

Microsatellite marker diversity in common bean (Phaseolus vulgaris L.)
Department for International Development (DFID)
Abstract
A diversity survey was used to estimate allelic diversity and heterozygosity of 129 microsatellite markers in a panel of 44 common bean (Phaseolus vulgaris L.) genotypes that have been used as parents of mapping populations. Two types of microsatellites were evaluated, based respectively on gene coding and genomic sequences. Genetic diversity was evaluated by estimating the polymorphism information content (…
