Crop yields in Sub-Saharan Africa (SSA) are typically less than half of yields in the developed world. With growing populations, and with climate change already beginning to put downward pressure on crop yields, intervention is urgently needed to enable farmers in SSA to produce more food. A key first step is to ensure that farmers have greater, and more reliable, access to high-quality seed of the modern varieties of climate smart crops that will best equip them to both feed themselves and produce food for barter or sale.

In many cases, breeding work for new varieties has been done. Farmers, however, are unaware of the new varieties, or seed of these varieties is not reaching them at meaningful levels. As a result, potential farmer yield and overall production levels for the target crops are not realised. The opportunity cost associated with this is significant and, without intervention, will grow as the effects of climate change increase.

Climate policy commonly carries an implicit assumption that incremental improvements in agricultural systems are adequate to make them resilient to climate change. In some cases, however, agricultural systems may cross certain environmental thresholds that require more transformational adaptation. Governments and development agencies need to improve their understanding of climate thresholds and their preparedness for transformational adaptation. Climate smart agriculture frameworks should consider the piloting of strategies for transformational adaptation.

CCARDESA ICKM System overview pamphlet.

CCARDESA aspires to be a regional knowledge hub that facilitates the sharing of agricultural information and research across the SADC region. Thus, CCARDESA has incorporated knowledge, information and communication as one of the key Thematic Focal Areas of the organisation.

CCARDESA undertakes programmes and projects that promote knowledge generation, knowledge management and dissemination of agricultural research through the utilization of Information and Communication Technologies (ICTs), among others. CCARDESA strives to ensure that credible information is made accessible to all interested stakeholders from policy makers to smallholder farmers.

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.

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 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.
