Économie et politiques novatrices pour une agriculture intelligente face au climat
 

Ressources

Le programme EPIC crée régulièrement plusieurs produits à l'intention du grand public, ainsi que des chercheurs, des spécialistes et des responsables politiques. La présente section renvoie à différentes ressources destinées aux décideurs politiques nationaux et internationaux, aux chercheurs et aux personnes qui souhaitent élargir leurs connaissances au sujet des liens entre l'atténuation du changement climatique, l'adaptation à ses effets et la sécurité alimentaire pour contribuer plus utilement à un dialogue ouvert et coopératif sur le changement climatique et l'agriculture. Nos produits utilisent les recherches et les expériences menées sur le terrain par le programme EPIC pour produire du matériel destiné à faciliter l'élaboration de politiques fondée sur des éléments concrets. 

La bibliothèque contient divers documents, dont des documents de travail, des notes d'orientation et des rapports. Si vous souhaitez vous inscrire sur notre liste de diffusion électronique et être tenu informé de nos dernières publications, veuillez nous écrire à l'adresse epic@fao.org.

Food security impact of agricultural technology adoption under climate change: Micro-evidence from Niger
An assessment of 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.

Abstract
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 household-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 rainfall 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.
