Do weather shocks worsen conflict around the world? To answer this question, this paper uses an innovative dataset created by using georeferencing to match weather and conflict data at the subregional level on a monthly frequency across 168 countries over 2013 to 2022.The empirical results show that higher temperature exacerbate conflict where it already exists. Estimations indicate that, in a high emissions scenario and all else equal, by 2060 conflict deaths as a share of the population for a median country facing conflict could increase by 12.3 percent due to rising temperatures. These findings underscore the importance of integrating climate resilience into peace and security efforts and designing climate adaptation policies that support conflict prevention and resolution.

We develop a quantitative spatial general equilibrium model with heterogeneous house-holds and multiple locations to study households’ vulnerability to food insecurity from cli-mate shocks. In the model, households endogenously respond to negative climate shocks by drawing-down assets, importing food and temporarily migrating to earn additional income to ensure sufficient calories. Because these coping strategies are most effective when trade and migration costs are low, remote households are more vulnerable to climate shocks. Food insecure households are also more vulnerable, as their proximity to a subsistence requirement causes them to hold a smaller capital buffer and more aggressively dissave in response to shocks, at the expense of future consumption. We calibrate the model to 51 districts in Nepal and estimate the impact of historical climate shocks on food consumption and welfare. We estimate that, on an annual basis, floods, landslides, droughts and storms combined generated GDP losses of 2.3 percent, welfare losses of 3.3 percent for the average household and increased the rate of undernourishment by 2.8 percent. Undernourished households experience roughly 50 percent larger welfare losses and those in remote locations suffer welfare losses that are roughly two times larger than in less remote locations (5.9 vs 2.9 percent). In counterfactual simulations, we show the role of better access to migration and trade in building resilience to climate shocks.

Depuis plusieurs années, le FMI publie un nombre croissant de rapports et autres documents couvrant l'évolution et les tendances économiques et financières dans les pays membres. Chaque rapport, rédigé par une équipe des services du FMI à la suite d'entretiens avec des représentants des autorités, est publié avec l'accord du pays concerné.

Niger’s new Poverty Reduction Strategy (PDES) represents its overarching reference framework for the government’s development agenda. It also proposes changes in policy orientation and institutional arrangements to respond to recent developments in Niger and in the subregion. The PDES was developed in an inclusive participatory process. Overall, it provides a comprehensive analysis of development challenges and a plan to achieve accelerated sustainable growth, identifies key risks to the achievements of the objectives as well as mitigating measures.
