Case Study

This Source-book is a particularly timely resource. It combines descriptive accounts of national and international experience in investing in agriculture with practical operational guidance on to how to design agriculture-for development strategies that capitalize effectively on the unique properties of agricultural growth and rural development involving women and men as a high-impact source of poverty reduction. It discusses gender equality and women’s empowerment.

This is a Vulnerability Sourcebook Annex for the Vulnerability Sourcebook Standardized vulnerability assessments support adaptation planning and evaluation sourcebook.

The sourcebook describes the National Adaptation Plan (NAP) process that aims at reducing the vulnerability of developing and least developed countries (LDCs) by addressing medium and long-term adaptation needs.

This framework provides a way of devising and applying case-specific vulnerability assessment methodologies.

The objective of this pilot project was to support communes in their efforts to identify, plan and implement climate adaptation measures that will help increase their resilience to climate change.

The goal of this factsheet with additional descriptions of Vulnerability Assessments (VA) applications is to provide an overview of experiences with VAs gained in Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) projects and make these experiences available to others. It has three sections.

This study analyzes possible impacts of projected future climate change on ecosystems of the Lake Chad Basin.

Food production is key to achieving food security in the drylands of sub-Saharan Africa. Since agricultural productivity is limited, however, due to inherent agro-ecological constraints and land degradation, sustainable agricultural intensification has been widely discussed as an opportunity for improving food security and reducing vulnerability. Yet vulnerability determinants are distributed heterogeneously in the drylands of sub-Saharan Africa and sustainable intensification cannot be achieved everywhere in cost-effective and efficient ways. To better understand the heterogeneity of farming systems’ vulnerability in order to support decision making at regional scales, we present archetypes, i.e. socio-ecological patterns, of farming systems’ vulnerability in the drylands of sub-Saharan Africa and reveal their nestedness. We quantitatively indicated the most relevant farming systems’ properties at a sub-national resolution. These factors included water availability, agro-ecological potential, erosion sensitivity, population pressure, urbanisation, remoteness, governance, income and undernourishment. Cluster analysis revealed eight broad archetypes of vulnerability across all drylands of sub-Saharan Africa. The broad archetype representing better governance and highest remoteness in extremely dry and resource-constrained regions encompassed the largest area share (19%), mainly indicated in western Africa. Moreover, six nested archetypes were identified within those regions with better agropotential and prevalent agricultural livelihoods. Among these patterns, the nested archetype depicting regions with highest erosion sensitivity, severe undernourishment and lower agropotential represented the largest population (30%) and area (28%) share, mainly found in the Sahel region. The nested archetype indicating medium undernourishment, better governance and lowest erosion sensitivity showed particular potential for sustainable agricultural intensification, mainly in western and some parts of southeastern and eastern Africa. Insights into the nestedness of archetypes allowed a more differentiated discussion of vulnerability and sustainable intensification opportunities, enhancing the evaluation of key interlinkages between land management and food security. The archetypes may support the transfer of successful intensification strategies based on similarities among the drylands in sub-Saharan Africa.

Southern African Agriculture and Climate Change: A Comprehensive Analysis examines the food security threats facing eight of the countries that make up southern Africa — Botswana, Lesotho, Malawi, Mozambique, South Africa, Swaziland, Zambia, and Zimbabwe — and explores how climate change will increase the efforts needed to achieve sustainable food security throughout the region. Southern Africa’s population is expected to grow at least through mid-century. The region will also see income growth. Both will put increased pressure on the natural resources needed to produce food, and climate change makes the challenges greater. Southern Africa is already experiencing rising temperatures, shifting precipitation patterns, and increasing extreme events. Without attention to adaptation, the poor will suffer.

Sustainability of rain-fed farming systems under climate variability and change conditions is a key concern for policy and adaptation planning processes to improve food and nutrition security. The challenge is to improve farming and tillage practices to enhance soil moisture availability and harvest excess runoff thereby making the farming systems more reliable and resilient to unpredictable risks of climate change and variability. In this short manuscript, an assessment of climate change impact on the agricultural water availability for rainfed systems in southern Africa is discussed through a pilot project conducted recently as part of climate change adaptation integrated modeling of crop-climate-soil systems. We consider the Pandamatenga plains in north-eastern Botswana, which was undertaken with the main indicators of crop yield impact with respect to soil water availability and excess runoff harvesting potential, for the current climatology (1971-2000) and projected over the coming decades up to the 2050s. The indicators of rainfed practices of growing maize, sorghum and sunflower are discussed, which are likely influenced not only by climate, but also the response requiring local and regional adaptation investments for improved food security and increase productivity. The manuscript recommends technical and policy interventions for incorporating climate change adaptation practices, with the view to outscale to national and possibly regional agricultural development planning processes.
