Forests’ Crucial Role in Global Crop Production Revealed by New Study
Table of Contents
A new study published in Nature Water highlights the notable dependence of global agriculture on atmospheric moisture originating from forests, even in distant countries. The research underscores the importance of forest conservation for safeguarding food security.
The Interconnectedness of Forests and Agriculture
Agricultural areas in 155 countries rely on atmospheric moisture from forests in other nations for up to 40% of thier annual rainfall, according to research published on November 4, 2024, in Nature water. This demonstrates a complex and frequently enough overlooked interconnectedness between ecosystems and food production systems.
Approximately 18% of precipitation in 105 countries is recycled from their *own* national forests, the study found. However, the larger impact comes from moisture transport *between* nations, highlighting the need for international cooperation in conservation efforts.
Key Countries and Their Roles
The Democratic Republic of Congo (DRC), Bolivia, Brazil, Peru, Canada, and Russia are identified as crucial suppliers of both moisture and crops. Together, these nations account for 13% of global crop production and 20% of global crop exports, according to the study.
Brazil, in particular, plays a significant role, supplying moisture to countries like Paraguay, Uruguay, and Argentina, while simultaneously importing crops from those same regions. This reciprocal relationship exemplifies the interconnectedness detailed in the research.

Agricultural Dependence and Forest Conservation
The study found that approximately 46% and 10% of highly dependent agricultural areas have their green and blue water requirements for all crops fulfilled
