    Food security and adaptation impacts of potential climate smart agricultural practices in Zambia 2015

    This paper analyzes how a set of widely promoted agricultural practices, including reduced tillage, crop rotations, legume intercropping as well as the use of modern inputs, affect crop yields and their resilience (i.e. probability of disastrously low yields) in Zambia using panel data from the Rural Incomes and Livelihoods Surveys (RILS). The RILS data are merged with a novel set of climatic variables based on geo-referenced historical rainfall and temperature data to understand whether and how the effects of the practices analyzed here change with climatic conditions. We estimate the impacts on the level of maize yields and the probability of very low yields controlling for time-invariant unobservable household characteristics. We find no significant impact of minimum soil disturbance, positive impact of legume intercropping and a negative impact of crop rotation on maize yields, which is off-set by a significantly positive impact under highly variable rainfall conditions. We also fi nd that the average positive impacts of modern input use are conditioned by climatic variables, whereas that of legume intercropping is robust to shocks. Timely access to fertilizer is the most robust determinant of yields and resilience. This paper provides important insights into the interplay between food security outcomes and climatic variables, and provides policy implications for targeted interventions to improve the productivity and the resilience of smallholder agriculture in Zambia in t he face of climate change.

    Addressing the 2030 Agenda on Climate Change and Food Security through Climate-Smart Agriculture - TCP/RAS/3604 2020

    Asia is a dynamic region for agricultural innovation. For decades, farmers have combined traditional practices and local knowledge with modern agricultural techniques, providing a strong foundation for “Climate-smart Agriculture (CSA)” approaches. CSA encompasses a range of established methodologies and technical approaches to address interlinked challenges in the agriculture and land-use sector: meeting demand for food, reducing greenhouse gas emissions in the global food system, and building the resilience of agricultural systems to the impacts of climate change. These priorities are also reflected in Nationally Determined Contributions (NDCs) submitted by countries under the Paris Agreement on Climate Change as part of the United Nations Framework Convention on Climate Change (UNFCCC). While instruments such as the Green Climate Fund (GCF), the Global Environmental Fund (GEF) and various mechanisms under multi-lateral development agencies can support the implementation of NDC priorities, countries have yet to translate broad these into national programmes or investment pi,nes. The potential of CSA approaches to enhance productivity and resilience, and to reduce emissions has been widely documented. However, efforts to systematically and rigorously integrate climate change across CSA’s three pillars are relatively untested in the region. The aim of the project was to support governments in six focus countries to develop national CSA programmes (and/or to integrate CSA priorities into existing plans and programmes), linking CSA investments to NDCs and global climate finance mechanisms, based on regional best practice and knowledge.

    Climate-smart agriculture for food security 2014

    Climate-smart agriculture (CSA) is an approach for transforming and reorienting agricultural systems to support food security under the new realities of climate change. Widespread changes in rainfall and temperature patterns threaten agricultural production and increase the vulnerability of people dependent on agriculture for their livelihoods, which includes most of the world’s poor. Climate change disrupts food markets, posing population-wide risks to food supply. Threats can be reduced by inc reasing adaptive capacity of farmers as well as increasing resilience and resource use efficiency in agricultural production systems. CSA promotes coordinated actions by farmers, researchers, private sector, civil society and policymakers towards climate-resilient pathways through four main action areas: 1) building evidence; 2) increasing local institutional effectiveness; 3) fostering coherence between climate and agricultural policies; and 4) linking climate and agricultural financing. CSA di ffers from “business-as-usual” approaches by emphasizing the capacity to implement flexible, context-specific solutions, supported by innovative policy and financing actions.
