Changements climatiques et réduction de la pauvreté

This policy brief by the Climate and Development Knowledge Network (CDKN) and the International Institute for Environment and Development (IIED) examines the intersection of climate change and poverty reduction. It argues that climate variability hinders the ability of poor populations to escape poverty and threatens the achievement of Millennium Development Goals (MDGs). The document advocates for integrating climate adaptation into national poverty reduction strategies, investing in evidence-based data, and ensuring that emission mitigation efforts provide tangible co-benefits for the poor.

• Climate change creates significant barriers to eradicating poverty, as increased climate variability makes it harder for impoverished people to escape poverty without relapsing. The document notes a consensus that climate change will severely test the ability to eliminate poverty in the medium term.
• Climate-related shocks have direct, negative impacts on health and nutrition, particularly for children in sub-Saharan Africa. In Ethiopia, children under five in drought-prone areas are 36% more likely to suffer from malnutrition, and those born during drought years are 41% more likely to experience stunted growth, resulting in approximately 2 million additional malnourished children. In Kenya, being born during a drought increases malnutrition probabilities by 50%, and in Niger, children under two born during drought years have a 72% higher chance of stunted growth.
• Climate change undermines the core pillars of poverty reduction strategies, including food, water, energy, and human security, as well as governance. Specifically, it is projected that climate change may increase the risk of famine by 30% by 2080, with women and children being the most affected. Changes in rainfall patterns can push water-precarious populations into poverty, and climate disasters disproportionately affect the survival rates of women and children during events like flash floods.
• Effective poverty reduction now requires 'climate-resilient development,' which necessitates merging adaptation and development policies. The document suggests that making MDGs climate-resilient in Africa over the next decade could require spending 40% more than in a scenario unaffected by climate change.
• While there is interest in 'triple win' solutions—projects that simultaneously achieve emission mitigation, poverty reduction, and adaptation—these have proven difficult to implement. Many Clean Development Mechanism projects have ignored poverty or avoided the poorest countries, and low-carbon energy access technologies often remain unaffordable for the poorest households due to high opportunity costs and lack of credit.
• The document recommends five key actions: investing in robust evidence bases on climate and poverty; applying development effectiveness lessons to adaptation; supporting country-specific integrated policies; involving climate-vulnerable poor populations in strategy design; and ensuring mitigation strategies also reduce poverty and support adaptation.
