Malnutrition and Climate in Niger
Malnutrition, particularly its impact on child morbidity and mortality, is one of the top five health effects of climate change. However, quantifying the portion of malnutrition attributed to climate remains challenging due to various confounding factors. This study examines the relationship between climate and acute malnutrition in Niger, a country highly vulnerable to climate change and disasters. Since climate's effect on malnutrition is indir…
Habitability for a connected, unequal and changing world
The concept of habitability is gaining momentum in climate and environmental studies. • Present conceptualizations lack socio-cultural integration and local context. • Need for intersectionally and locally differentiated assessments of habitability. • Full understanding of habitability need to consider connectivity and tele-coupling. • Research should integrate diverse methodologies and local perspectives. As global climate change intensifies, th…
Rendre compte de l'insaisissable
Au Sénégal, l’agriculture est majoritairement pluviale et fortement dépendante de services météorologiques. Ainsi, toute information sur la pluviométrie à venir est importante pour les cultivateurs afin d’anticiper l’arrivée tardive des pluies ou d’années particulièrement sèches. En pays sereer (région de Fatick), les Saltigui (devins) participent à ce travail d’anticipation de la saison des pluies à travers des pratiques de divination qui permet…
Farmers’ Perception and Adaptation Strategies to Climate Change in Central Mali
Adaptation of the agricultural sector to climate change is crucial to avoid food insecurity in sub-Saharan Africa. Farmers’ perception of climate change is a crucial element in adaptation process. The aim of this study was (i) to compare farmers’ perception of climate change with actual weather data recorded in central Mali, (ii) to identify changes in agricultural practices implemented by farmers to adapt to climate change, and (iii) to investig…
Impacts of Greenland and Antarctic Ice Sheet melt on future Köppen climate zone changes simulated by an atmospheric and oceanic general circulation model
Weather-index drought insurance in Burkina-Faso
By using a detailed agricultural and climate dataset over Burkina-Faso and simple assumptions regarding the form of an insurance contract, the authors investigate the potential economic efficiency for farmers of a weather-index insurance system in this country. To do so, the results of more than 3000 simulated contracts applied to 30 districts, 21 yr (1984–2004), and five crops (cotton, millet, sorghum, maize, and groundnut) are explored. It is f…
The impact of future climate change on West African crop yields
Symposium on Social Theory and the Environment in the New World (dis)Order ; International audience ; In West Africa, agriculture, mainly rainfed, is a major economic sector and the one most vulnerable to climate change. A meta-database of future crop yields, built up from 16 recent studies, is used to provide an overall assessment of the potential impact of climate change on yields, and to analyze sources of uncertainty. Despite a large dispersi…
Changement climatique
La mobilisation autour de la conférence Paris Climat 2015 (COP 21) est l'occasion de mettre en relief la vulnérabilité des milieux et des populations du Sud face au réchauffement climatique. Certaines régions de la zone intertropicale en subissent déjà les effets, que ce soient les vagues de chaleur au Sahel, la perturbation des systèmes de mousson, la fonte des glaciers andins, les menaces sur la biodiversité, l'élévation du niveau des océans...…
Climate change
The mobilisation centred on the 2015 Paris Climate Conference (COP 21) is an opportunity to highlight the vulnerability of environments and populations in the South in the face of climate warming. Some tropical regions are already suffering from its effects, with heat waves in the Sahel, disturbances to monsoon systems, the melting of the Andean glaciers, threats to biodiversity, a rise in sea level and other features. Research conducted by IRD a…

Errors and uncertainties introduced by a regional climate model in climate impact assessments
The challenge of estimating the potential impacts of climate change has led to an increasing use of dynamical downscaling to produce fine spatial-scale climate projections for impact assessments. In this work, we analyze if and to what extent the bias in the simulated crop yield can be reduced by using the Weather Research and Forecasting (WRF) regional climate model to downscale ERA-Interim (European Centre for Medium-Range Weather Forecasts (EC…
Adaptability of Mediterranean Agricultural Systems to Climate Change
The adaptability of olive-growing systems to climate change is studied in the Sierra Mágina region (Andalusia) using an interdisciplinary approach that evaluates and makes associations across climate, water resources, and socioeconomic strategies. First, the evolution of rainfall and temperature during the twenty-first century is assessed at the local scale using 17 regional climate model (RCM) simulations. A 15%–30% rainfall reduction is expecte…
Robust features of future climate change impacts on sorghum yields in West Africa
West Africa is highly vulnerable to climate hazards and better quantification and understanding of the impact of climate change on crop yields are urgently needed. Here we provide an assessment of near-term climate change impacts on sorghum yields in West Africa and account for uncertainties both in future climate scenarios and in crop models. Towards this goal, we use simulations of nine bias-corrected CMIP5 climate models and two crop models (S…

Future changes in precipitation and impacts on extreme streamflow over Amazonian sub-basins
Because of climate change, much attention is drawn to the Amazon River basin, whose hydrology has already been strongly affected by extreme events during the past 20 years. Hydrological annual extreme variations (i.e. low/high flows) associated with precipitation (and evapotranspiration) changes are investigated over the Amazon River sub-basins using the land surface model ORCHIDEE and a multimodel approach. Climate change scenarios from up to ei…

Estimating the Potential Economic Value of Seasonal Forecasts in West Africa
Recent improvements in the capability of statistical or dynamic models to predict climate fluctuations several months in advance may be an opportunity to improve the management of climatic risk in rain-fed agriculture. The aim of this paper is to evaluate the potential benefits that seasonal climate predictions can bring to farmers in West Africa. The authors have developed an archetypal bioeconomic model of a smallholder farm in Nioro du Rip, a …

Response of the South Indian runoff-harvesting civilization to northeast monsoon rainfall variability during the last 2000 years
Compared with the southwest monsoon, the mechanisms and history of northeast monsoon (NEM) variability over South Asia are poorly known. The NEM nevertheless contributes >50% of rainfall to semi-arid southeast India, and has underpinned the success, over the last 2000 years, of a widespread indigenous water resource management system based on rainwater harvesting and storage in man-made lakes. Based on a power spectrum analysis of 60- to 100-yr i…
