About this site:

The purpose of this site is to gather content — including blogs, research outputs and project updates —from the research and work on climate change at the International Food Policy Research Institute (IFPRI). IFPRI researchers and their many partners and collaborators seek to assist small-scale farmers to find ways to sustainably adapt to and build resilience toward a changing climate. The CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) funds much of the climate-related work at IFPRI, which spans the globe from Latin America, Africa, to South and South East Asia.

It began with an innocent enquiry: do we have relative humidity data, under climate change for possible future situations, that could be used to think about a direct effect on animal productivity?

Currently, in our economic modeling, the cattle, hogs, chickens, etc., are only indirectly affected by changes in feed/fodder prices when those are affected by climate change. But, we are not capturing any direct effect from hot animals.

We would like to end up with global maps of some index that can tell us something about the stress that animals would experience under typical conditions at each place on the map.

The problem, of course, is that the climate data we normally use for crop modeling do not include relative humidity. That is not quite right: some of the raw data do, but not in the data we have cleaned up and arranged for using in the crop models. In order to try to keep things internally consistent, we would like to build up a rough approximation based on what we do have.

It's so hot, even the corn is sweating!1


Can temperatures this high be good for corn? It turns out that the answer is "no". I know this because last week I completed a study of the effects of temperature on U.S. corn. My goal was not only to be able to estimate the effects of climate change on corn yields in the future, but also to understand the best way to apply temperature data to the analysis.  One of the things I did was to follow the lead of other researchers and convert daily maximum and minimum temperatures to essentially hourly temperatures to be able to see the effect of an hour at each 1-degree interval on yields.Read more

IFPRI BLOG: Global trends plus local decisions equals a more food-secure world by 2050

January 11, 2016

By Emil Caillaux

Achieving food security is one of the essential components of the UN Sustainable Development Goals (SDGs), which were adopted in September of last year. While only a few goals specifically mention forestry and other land-based sectors, all 17 depend on healthy and sustainable landscapes for their achievement.

Over the past two years, the Global Landscapes Forum (GLF) has evolved into the world’s leading platform for discussing land-use issues. In Paris this past December, the Forum brought together approximately 3,200 stakeholders from across sectors, including forestry, agriculture, water, energy, law and finance.

At GLF in Paris, IFPRI staff hosted a discussion forum on the challenges faced by the agricultural sector due to climate change, and the available options in regional and global policies that could lead to healthy growth and stability.

Do Economic Predictions of Damage from Climate Change Cause Policymakers to Focus on the Wrong Thing?

December 2, 2015

By Timothy S. Thomas

I have been computing various measures of the impact of climate change on agriculture for the last six years, in an effort to help donors, researchers, and policymakers anticipate what farmers would face and, as a result, be able to develop plans to help agriculture adapt to climate change. But I recently came to the realization that the measures I have been computing -- while important for many reasons -- actually lead the policymaker to potentially wrong conclusions about what policies and investment strategies to use in order to help farmers adapt. The trouble is that the kind of calculations I have been doing are similar to the calculations others throughout the world have been doing, so it is not simply a matter of me being wrong, but a matter of all of us thinking about the issue incorrectly.

POLICY SEMINAR – Climate Change & Food Security: Challenges and Options at Global and National Scales

November 30, 2015

As scientists, advocates, researchers, and political leaders prepared to head to Paris for Conference of Parties (COP21), a panel of experts laid out some of the most urgent aspects of climate change and agriculture. Join IFPRI as new results on the impact of climate change on agriculture and food security from the International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT) are presented, along with a modeling framework and results designed to assist national decision- and policy-makers address climate change and mitigation goals in a politically and economically sustainable way. Following presentations by senior IFPRI researchers Alex de Pinto and Keith Wiebe, a panel of experts shared their views and recommendations.

IFPRI BLOG: Why paying attention to gender matters for climate change adaptation

November 17, 2015

By Elizabeth Bryan, Patti Kristjanson, and Claudia Ringler

Until recently, there has been little evidence supporting the need to focus on the gendered dimensions of agriculture and climate change. Why? Because few researchers have been talking to women in agriculture as well as men--both of whom contribute to solving the food security challenges posed by climate change.

CCAFS Info Note: Climate readiness indicators for agriculture

November 5, 2015

By Eva Wollenberg, Monika Zurek and Alex De Pinto

Coping with climate change in agriculture while ensuring food security and reducing greenhouse gas emissions or emission intensities will require new information, technologies, finance instruments and possibly new institutions. Many countries are building these capabilities now, but there is much uncertainty about what is needed and what is feasible.

Building the Case for Climate Change-Resilient Agriculture in the Philippines

October 7, 2015

By Ioannis Vasileiou

They say policies and politics are much about timing. Many would argue that development is a political process itself. Thus, when travelling to the Philippines earlier this fall to participate in a Policy Forum, just a few weeks before the world is supposed to achieve a universal agreement on climate, and while the region is experiencing the effects of what is widely considered one of the worst El Niño phenomenons in years, a rigorous dialogue was expected -- one focusing on the intersection between climate change and agriculture.

And that’s what happened.Read more

Key Policy Ideas to Help Philippine Agriculture to Prosper Under Climate Change

October 2, 2015

By Timothy S. Thomas and Mark W. Rosegrant

Plane model tested inside a wind tunnel.

Before a new passenger jet is built, a much smaller model of the jet is built and then tested in a wind tunnel.  The wind tunnel shoots very fast moving air past the model, revealing important information about airflow over the wing and structural stability of the aircraft under various conditions. Testing a model in this way helps engineers catch any unanticipated problems their design might have, and then make corrections before large amounts of money are invested to construct the actual jet and make it ready for flight.Read more

IFPRI and PAPAC Technical Workshop in Tanzania: CSA tools and technologies for improved policy making

September 25, 2015

17185080126_deccdabcf5_zIFPRI scientists are working with Tanzanian partners to design and deliver new tools and techniques to build resilience to climate and weather related risks through measures to promote climate smart agriculture (CSA).

This is part of the partnership to deliver on the CGIAR alignment to the CAADP principles, specifically the Malabo Declaration and subsequent targets in combating climate change.
