    This brief summarizes the results of a comprehensive national representative plot-level survey with a wealth of socio-economic information merged with geo-referenced climatic information. We assess factors affecting the adoption of agricultural technologies under climate risk and evaluate the impact of adoption on food security in Niger. Specifically, we look at how bio-physical and climatic factors affect a set of agricultural practices known to increase resilience and productivity. We analyse the relationship between type of practice and crop productivity for a range of different farmer types, and under a range of biophysical and climate conditions.

    Food security impact of agricultural technology adoption under climate change
    Micro-evidence from Niger

    We assess farmers' incentives and the conditioning factors that hinder or promote adoption of agricultural technologies under climate risk and evaluate its impact on food security in Niger. We distinguish between (i) exposure to climatic disruptions, (ii) bio-physical sensitivity to such disruptions, (iii) household adaptive capacity in terms of farmers’ ability to prepare and adjust to the resulting stress, and, finally, (iv) system-level adaptive capacity that serve as enabling factors for hou sehold-level adaptation. We employ multivariate probit and instrumental variable techniques to model the selection decisions and its impact. The results clearly indicate that while the use of modern inputs and organic fertilizers significantly improves crop productivity, results are unclear for the impact of crop residues. Moreover, factors driving modern input use are different than those of crop residues and organic fertilizer which can be characterized at low investment capital requirements, higher labour requirements and longer time for results versus modern inputs which can be characterized as higher investment capital requirements, less labour requirement and shorter time for returns. Exposure to climatic stress and bio-physical factors are identified as key factors that hinder or accelerate adoption. Results also show that greater climate variability as represented by the coefficient of variation of rainfall and temperature and recent climate shocks as represented by average rai nfall shortfall increases use of risk-reducing inputs such as crop residue, but reduce the use of modern inputs. In addition, the key role of system-level adaptive capacity in governing input use decision. Results presented have implications for understanding and overcoming barriers to selection for each practice, distinguishing structural aspects such as exposure and sensitivity from potential interventions at the household or system levels linked to adaptive capacity.

    The Assessments of Climate Change Impacts and Mapping of Vulnerability to Food Insecurity under Climate Change to Strengthen Household Food Security with Livelihoods’ Adaptation Approaches (AMICAF)

    The Assessments of Climate Change Impacts and Mapping of Vulnerability to Food Insecurity under Climate Change to Strengthen Household Food Security with Livelihoods’ Adaptation Approaches (AMICAF) is a project supported by the Food and Agriculture Organization (FAO) that aims to assist developing countries in climate change assessment and adaptation to improve food security. The AMICAF Project started in October 2011 with a budget of US$ 2.5 million and is implemented in the Philippines and Per u.
