Beaucoup d’études économétriques évaluent l’impact du changement climatique sur l’agriculture en supposant les prix agricoles exogènes. Si les variables climatiques influencent ces prix, il en résulte un « biais de prix », dont on reconnaît l’existence mais qui n’a jamais été quantifié. Nous quantifions ce biais dans le cas du Burkina Faso, avec un...

BackgroundDengue dynamics result from the complex interactions between the virus, the host and the vector, all being under the influence of the environment. Several studies explored the link between weather and dengue dynamics and some investigated the impact of climate change on these dynamics. Most attempted to predict incidence rate at a country...
L’évaluation de la vulnérabilité des cultures sélectionnées au Sénégal est basée sur leur sensibilité au changement, leur exposition et leurs capacités d’adaptation. Le but ultime de cette étude est d’évaluer si le climat futur a un impact neutre, négatif ou positif (pas de changement/diminution/augmentation) sur la productivité des cultures, et d’...
The northeast region of Cote d’Ivoire, where agriculture is the main economic activity, is potentially vulnerable to extreme climatic conditions. This study aims to make a comprehensive spatio-temporal analysis of trends in extreme indices related to precipitation and temperature for the Zanzan region of Cote d’Ivoire over the period of 1981–2020. ...
Training material from the CCAFS Project "Upscaling promising livestock options for mitigating greenhouse gas emissions in Asia". The material includes a report on mitigation options for feed management, a report on mitigation options for manure management, and a report on the total farm approach and a brief for term explanations.
The need to support existing sewage systems is obvious due to the noticeable consequences of climate change, such as extreme rainfall, which is causing more urban flooding. It is believed that these phenomena will intensify in the long-term, and that sewage systems will be overloaded with stormwater. Consequently, cities will need more opportunitie...
This document reports on preliminary findings from a household survey conducted in Meru County under the auspices of the Innovation for African Climate Risk Insurance (INACRI). The project aims to develop an improved crop insurance index that addresses basis risk inter alia for small scale maize farmers. The goal of the household survey was to asse...

Assessing variations in the annual runoff coefficient (RC) on a basin scale is crucial for understanding the hydrological cycle under natural and anthropogenic changes, yet a systematic global assessment remains unexamined from a water-balance perspective. Here, we combine observation-based runoff and precipitation datasets to quantify basin-averag...
The United Nations Food Systems Summit aimed to chart a path toward transforming food systems toward achieving the Sustainable Development Goals. Despite the essentiality of water for food systems, however, the Summit has not sufficiently considered the role of water for food systems transformation. This focus is even more important due to rapidly ...
