Climate change and variability: What are the risks for nutrition, diets, and food systems?

By Jessica Fanzo, Rebecca McLaren, Claire Davis, and Jowel Choufani

The paper uses a food systems approach to analyze the bidirectional relationships between climate change and food and nutrition along the entire food value chain. It then identifies adaptation and mitigation interventions for each step of the food value chain to move toward a more climate-smart, nutrition-sensitive food system. The study focuses on poor rural farmers, a population especially vulnerable to the adverse effects of climate change on nutrition, although we recognize that there are other vulnerable populations, including urban poor and rural populations working outside of agriculture. Although this report does not explicitly exclude overweight and obesity, it focuses primarily on undernutrition because this nutritional status is currently more prevalent than overnutrition among our target population.

Future scenario development now added to Cambodia’s policy landscape

Cross-post from CCAFS

Today, Cambodia’s Climate Change Priorities Action Plan for Agriculture (CCPAP) features a scenario-guided priority-setting for Cambodia in the face of climate change, and a strong focus on climate-smart agriculture. In the plan, key practices and financial allocations have been set up to translate those words into actions.






New paper analyses country strategies that reduce drought-related risks for farmers

By Nicola Cenacchi, IFPRI

Droughts are a common occurrence worldwide, but major concerns are growing over their long-term disruption to global agricultural production. This year alone, droughts have damaged the coffee industry in Brazil and caused the death of hundreds of cattle, and losses to staple crops in Central America, triggering food shortages, higher prices, and ultimately threatening the food security of poor households across the region.






Exploring the climate-conflict nexus in Sudan

There has been a growing interest in understanding the ways in which extreme weather events and resource scarcity may trigger conflict.

Vulnerability to both climatic and violent shocks varies across the globe and depends on various factors that usually make poor areas more likely to be affected. The Horn of Africa -the region in Sub-Saharan Africa (SSA) with the largest concentration of pastoralists- is extremely vulnerable. This part of the African continent has experienced high conflict levels and it is prone to climatic fluctuations that can have dramatic consequences on its rural population.






Building the scientific basis for climate-smart agriculture

Cross-post from IFPRI blog

Climate change is already putting food security at risk. Rising temperatures and extreme events, such as sudden droughts and floods, mean that it will be even harder to meet the growing demand for food, fiber and fuel, especially for poor countries with high population growth.

Unless immediate action is taken by policy-makers, the impacts on livelihoods will increase over the long-run, especially if agriculture expands onto wild-lands that now provide natural resources such as clean water and biodiversity.






US and African leaders discuss challenges to build climate resilience and ensure food security

Cross-post from CCAFS blog

Arame Tall, climate-service scientists working with the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) while located at the International Food Policy Research Institute (IFPRI), is here providing a report back from a recently held US-Africa Leaders’ Summit, and a special high-level session entitled “Resilience and Food Security in a Changing Climate” at the National Academy of Sciences in Washington, D.C.






Project: Global agricultural model intercomparisons

What is the challenge? Climate change poses significant challenges to agriculture and food security, but our understanding of these challenges, their impacts, and options to address them is limited by the data and modeling tools available. This activity contributes to systematic intercomparisons across leading global modeling efforts, linking climate, crop and economic models, as a basis for improvement in the models and ultimately in our understanding of impacts and possible responses.

Southern African agriculture and climate change

A comprehensive analysis Southern African Agriculture and Climate Change: A Comprehensive Analysis examines the food security threats facing eight of the countries that make up southern Africa — Botswana, Lesotho, Malawi, Mozambique, South Africa, Swaziland, Zambia, and Zimbabwe — and explores how climate change will increase the efforts needed to achieve sustainable food security throughout the region. Southern Africa’s population is expected to grow at least through mid-century. The region will also see income growth. Both will put increased pressure on the natural resources needed to produce food, and climate change makes the challenges greater. Southern Africa is already experiencing rising temperatures, shifting precipitation patterns, and increasing extreme events. Without attention to adaptation, the poor will suffer.

New report reveals how climate change will hit West Africa

By Gerald Nelson

Today, IFPRI launches West African Agriculture and Climate Change, the first of three monographs on climate change and agriculture in West, Central, and Eastern Africa. The monographs result from a research project headed by IFPRI Senior Researcher Gerald Nelson. Below Nelson talks about his research and implications for policymakers.
