Climate change and proliferation of natural disasters, such as earthquakes, increasing price of depleting resources (including food) associated to higher volatility and more frequent cyclical economic crises will affect the fight against poverty in the future years. Policies should include strategies to deal with risk (insurance, prevention, mitigation and coping). The objective of this Task 9.3 is to precisely assess, in different context the effects of natural disasters on populations living conditions. It includes four researches:
1- The first research, conducted by Consortium pour la Recherche Economique et Sociale (CRES, Dakar) brings new empirical evidence of the impacts of various types of catastrophes on poverty in developing countries. Results show that catastrophes have a strong and significant impact on the prevalence of poverty. This influence is nevertheless mitigated as the country reaches relatively higher levels of development or when it benefits from international remittances.
2- The second research, carried out by Luxembourg Institute of Socio-Economic Research (LISER), deals with the effect of Warming, Rainfall and farmer’s technical efficiency in Mali. This study comes to the conclusion that instability in temperature and rainfall are important factors of inefficiency.
3- The third research was done by Tecnológico de Monterrey (ISTEM-EGAP) and aims at understanding the systemic complexity of mechanisms channeling the impact of natural disasters on poverty in Mexico municipalities. Analyses show that natural disasters have two channels through which they influence vulnerability: decreasing the physical capital and diminishing human capacity. These effects are persistent overtime.
4- The last research, conducted by IRD-DIAL, assessed the long-lasting impact of the 2010 Earthquake in Haiti. It finds strong evidence of a negative and significant impact of the earthquake on households’ asset index indicating that, three years after the event, families from affected areas had not yet recovered from the shock.
