Cassava is the second-most important staple food crop after maize in Malawi. The availability of different varieties of cassava allow for both commercial use and household consumption of cassava to hedge against food insecurity. Malawi is prone to drought due to climate change vulnerability, poor agricultural practices and high population growth making cassava, a drought-resistant crop, an attrac- tive option.

This study sets out to answer the question of whether cassava is, indeed, the 21st century crop for smallholders. The focus lies on smallholder production sys- tems in Nkhotakota District on the shores of Lake Malawi and in the rural vicinity of Lilongwe, the capital city. A nexus between the household asset endowments of smallholder farmers and their participation in the value chain was examined to identify root causes of the supply-demand mismatch and to formulate recom- mendations for effective value chain development. A partial value chain analysis has been conducted to account for the participation of smallholders in the value chain. We chose a structural analysis over an economic analysis, as prices are high- ly volatile in the informal markets of Malawi and notoriously difficult to solicit from actors. Since the responsibility for the production of food and cash crops falls broadly along gender lines within a household, gender aspects take a central role in our research. All our instruments included gender differentiated elements.

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.

This presentation discusses enhancing evidence based climate change adaptation research and policy for agriculture in southern Africa.

Agriculture is a risky business and farmers face a host of market and production risks that make their incomes volatile from year to year. These risks include yield losses due to bad weather, pests and diseases; post-harvest losses during storage and transport; and unexpectedly low market prices. In many cases, farmers are also confronted by the risk of catastrophic losses, for example, when crops or livestock are destroyed by drought, re or new pest outbreaks, or when lives and assets are lost due to extreme weather events like hurricanes and oods. These risks can pose challenging nancial problems even for large commercial farms in developed countries, but the consequences for vast numbers of smallholders around the developing world are much more severe. Major shocks to household incomes, food consumption and assets worsen poverty and lead to episodic humanitarian crises that require large- scale relief interventions.

CCARDESA's Climate Change Adaptation Strategy: Evidence from CCARPASA Project

Improving agricultural water productivity, under rainfed or irrigated conditions, holds significant scope for addressing climate change vulnerability. It also offers adaptation capacity needs as well as water and food security in the southern African region. In this study, evidence for climate change impacts and adaptation strategies in rainfed agricultural systems is explored through modeling predictions of crop yield, soil moisture and excess water for potential harvesting. The study specifically presents the results of climate change impacts under rainfed conditions for ma- ize, sorghum and sunflower using soil-water-crop model simulations, integrated based on daily inputs of rainfall and evapotranspiration disaggregated from GCM scenarios. The research targets a vast farming region dominated by heavy clay soils where rainfed agriculture is a dominant prac- tice. The potential for improving soil water productivity and improved water harvesting have been explored as ways of climate change mitigation and adaptation measures. This can be utilized to explore and design appropriate conservation agriculture and adaptation practices in similar agro-ecological environments, and create opportunities for outscaling for much wider areas. The results of this study can suggest the need for possible policy refinements towards reducing vulne- rability and adaptation to climate change in rainfed farming systems.

This Literature Review is the rst step towards a comparative assessment of Weather Index Insurance (WII) in the agricultural sector in East and Southern Africa. The second step involves visits to four countries (Kenya, Tanzania, Zimbabwe, and Zambia) covered by the Climate Smart Agriculture Programme (Vuna) funded by DFID, which have weather index insurance programmes. The visits will allow collection of information on the recent performance of those programs and obtain the perceptions of key stakeholders on lessons learned, constraints, sustainability, and potential of those insurance programmes to address issues related to strengthening the resilience of agricultural systems to weather risk. The ndings from both stages will be summarised in an Evidence and Learning Report focussing on the determinants of success or failure of the programmes under implementation.

This paper summarizes the main ndings of the global experience on the implementation of WII specically the lessons learned on the mechanics of the index, pro tability, bundling, impacts, and potential role in climate change adaptation. It also discusses the challenges of current pilot projects in East and Southern Africa, wherever secondary information is available.

This paper presents a review of the commercial sustainability, profitability, challenges, impact, and potential contribution of weather index insurance (WII) products to improving resilience in weather-affected agricultural systems in developing countries. This is important given the continuing demand on governments to manage the considerable weather risk faced by smallholders in Sub-Saharan Africa and other weather-exposed regions in developing economies.

This assessment has been developed in a two-step process. First, a literature review was conducted summarising the global experience in developing weather index insurance programmes. Second, we conducted a field investigation designed to extract a more detailed understanding of whether the results of recently launched WII pilots in Sub-Saharan Africa (in Kenya, Tanzania, Zambia, and Zimbabwe) are in line with the global experience.

Effective scaling up is a key measure of success for an innovation or intervention. A new approach is typically tested in a pilot project that has limited reach. With monitoring and evaluation (M&E), the lessons learned from the pilot can be used to scale up the model to create larger socioeconomic and developmental impacts. The decision to scale up, however, is often made with incomplete information. Given the high cost of scaling up, it is important for governments and development partners to carefully decide which innovations are ready for further investment. A good understanding of the scaling-up process and a framework for analysing scalability is critical for informed decision-making.
