About Soils

Soils research is fundamental and multidisciplinary, addressing natural resource management issues from farm to landscape scales, with a strong focus on soil science. Our cross-cutting research links CIAT’s research in crop improvement and policy analysis to vital work on agricultural production systems across landscapes. We believe this integrated approach is essential for reducing hunger, while reversing land degradation and making agriculture climate smart.

Land Degradation

Land Degradation

Land degradation is widespread across the tropical world. Restoring soils and land is a central requirement for reducing hunger and poverty through sustainable growth in agriculture. CIAT works toward this end through research on soil and landscape health, ecosystem services, tradeoff modeling, and sustainable land management.

Sustainable Intensification

Sustainable Intensification

Tropical soils account for about 40% of the earth’s land area and support about the same proportion of the world population.  Given population growth and the limited amount of land available for agricultural expansion, intensifying agricultural production while maintaining important ecosystem functions are urgent imperatives. CIAT soil scientists contribute by helping to improve agricultural productivity, enhance nutrient-use efficiency, and apply more widely the concept of integrated soil fertility management.

Climate Change Adaptation and Mitigation

Climate Change Adaptation and Mitigation

More severe and variable weather together with growing uncertainty about the future climate pose major challenges for tropical agriculture worldwide and particularly for smallholder farmers. Convinced that soils research is critical for meeting the challenges, CIAT soil scientists are seeking ways to advance climate change adaptation and mitigation through improvements in soil management that heighten the resilience of production systems and enhance the provision of ecosystem services.

Soils Blog

The Soils Blog is written by members of CIAT’s Soils Research Area, an interdisciplinary group conducting cross-cutting research that is central to CIAT’s mission of combating hunger and poverty by making agriculture more eco-efficient. CIATs soil scientists work across the tropics to alleviate land degradation, boost soil fertility, and make agriculture more climate smart.

Down to earth data

  “Diversity.” It’s not often you get a one word answer from researchers, given the complexity of their work, but that’s the answer CIAT’s soil scientist Rolf Sommer gave when asked his impression of Lushoto district nestling in north-eastern Tanzania’s Usambara Mountains. Then he was whisked off into a meeting.>

Could climate change spell trouble for Kenya’s largest river?

This post first appeared on the Thomson Reuters Foundation climate blog.  Ahead of the Global Landscape Forum in Peru, it helps to remember exactly why landscapes are important. They give us the bigger picture, to connect the dots between the many people who use an ecosystem and what for. It’s that bigger>

Simple yet comprehensive: A tool for outscaling Climate Smart Agriculture practices

Using participatory methods, scientists are now working with farmers to understand climate impacts on farming systems and rural livelihoods and to identify locally appropriate climate-smart solutions. Temperature and rainfall in East Africa are increasingly variable but farmers’ ingenuity and enthusiasm among researchers keeps agriculture moving in the Southern Agricultural Growth>

Let’s think deeper

This is the invitation from Ngonidzashe Chirinda, a soils researcher at CIAT that is more than interested in finding a concrete answer to a complex challenge in deeper layers of soils: how do we cost-effectively get the carbon to deeper soils layers? In order to store more of it and>
