There is a growing realization that climate change is real and is happening. In fact, more recent studies indicate that climate change is happening faster than that envisaged by the IPCC and that the impacts are overshooting even the worst case scenarios that were predicted. The 2007 IPCC assessment, the most comprehensive and respected analysis of climate change and its impacts involving thousands of scientists from about 130 countries, has provided sufficient evidence to conclude that the...

The Intergovernmental Panel for Climate Change (IPCC) projections for Southern Africa (based on the outputs of 21 Global Circulation Models (GCM), using the A1B greenhouse gas emission scenario) suggest average annual temperature increases of 3.1°C and changes in annual rainfall of between ‐12 and +6%. Atmospheric carbon dioxide levels for this scena rio are expected to increase to around 700ppm from the current 370ppm. How might these changes impact on crop productivity in the drier...

Library has French version: Kenya : ameliorer les strategies adaptatives des agriculteurs en integrant les savoirs endogenes en matiere de prevision et d'adaptation climatiques

SUMMARY This study examines farmers’ perceptions of short- and long-term variability in climate, their ability to discern trends in climate and how the perceived trends converge with actual weather observations in five districts of Eastern Province in Kenya where the climate is semi-arid with high intra- and inter-annual variability in rainfall. Field surveys to elicit farmers’ perceptions about climate variability and change were conducted in Machakos, Makueni, Kitui, Mwingi and Mutomo...

Scenario analysis using data generated from APSIM model was conducted to investigate the effect of soil and water conservation practices (tied ridges and mulching) on grain yield of improved maize varieties (Katumani and Makueni) generated with and without N fertilizers under below normal (<250 mm), normal (≥250 < 350 mm) and above normal seasons (≥350 mm) in two sites, Katumani and Makindu in Machakos and Makueni counties Eastern Kenya. Results indicate that the yields were significant...

This book summarizes the evidence from different African countries about the local impacts of climate change, and how farmers are coping with current climate risks. The different contributors show how agricultural systems in developing countries are affected by climate changes and how communities prepare and adapt to these changes.

Rain-fed agriculture will remain the dominant source of staple food production and the livelihood foundation of the majority of the rural poor in sub-Saharan Africa (SSA). Greatly enhanced investment in agriculture by a broad range of stakeholders will be required if this sector is to meet the food security requirements of tomorrow's Africa. However, production uncertainty associated with between and within season rainfall variability remains a fundamental constraint to many investors who...

Three experiments were conducted to evaluate the performance of maize, sorghum, common bean and pigeon pea varieties under different water management in a cool and wet region of Central Kenya, as a part of the studies at analogue sites. The first experiment evaluated the growth and performance of three varieties (early maturing: EM, medium maturing: MM and late maturing: LM) of maize (Zea mays L), sorghum (Sorghum bicolor L.), pigeon pea (Cajanus cajan) and common bean (Phaseolus vulgaris...

From 2011 to 2014, the CALESA project was a research-for-development project which coupled integrated climate risk analyses, crop growth simulation modelling and field-based research both on-station and on-the-ground with participatory research with farmers. It comprised research-oriented activities for knowledge and technology creation, and development-oriented activities for information sharing and capacity building. The main purpose of the CALESA project was to develop sound adaptation...

In this study, we assessed the possible impacts of climate variability and change on growth and performance of maize using multi-climate, multi-crop model approaches built on Agricultural Model Intercomparison and Improvement Project (AgMIP) protocols in five different agro-ecological zones (AEZs) of Embu County in Kenya and under different management systems. Adaptation strategies were developed that are locally relevant by identifying a set of technologies that help to offset potential...

This study evaluates the impacts of climate change and an adaptation strategy on agriculture in the Wami River sub-basin in Tanzania. This study uses the Agricultural Model Improvement and Inter-comparison Project (AgMIP) framework that integrates climate, crops and economic models and data using a novel multi-model approach for impact assessment of agricultural systems under current and future conditions. This study uses five Global Circulation Models (GCMs) from the fifth phase of the...
