This document summarizes the development of agriculture in Brazil and discusses potential impacts of climate change and policy alternatives. Key points:
1) Brazilian agriculture transformed from low production to highly productive through increased yields, new technologies, and expansion into new areas.
2) Climate change may impact crop yields and suitable land for agriculture in Brazil according to models, though effects are uncertain.
3) Brazil has implemented policies like its Agricultural and Livestock Plan to promote no-till farming, integrated systems, and degraded pasture recovery to mitigate emissions.

2. Outline
• Recent agricultural development;
• Potential impact of climate change on agricultural
production;
• Some policies alternatives to mitigate carbon
emissions;
4. Overview
Brazilian Ag before the 1970’s
Low Ag production and low yields;
Production concentrated in South/Southeast;
MAPA (2010). Food supply crisis;
Rural poverty;
Lack of specific knowledge on Tropical
Agriculture;
Institutional void (ag research, education,
markets, media governmental agencies, etc.).

25. Concluding Remarks
• The experience of Brazil’s agricultural transformation is proof that it
is possible to have an efficient and competitive agriculture in the
tropics;
• The development of Brazilian agricultural was predominantly based
on productivity gains;
• There are clear opportunities to expand food, biofuels and fiber
production in a sustainable way in Brazil. Intensifying pastoral
systems will be of central importance;
• Projected effects of climate change in Brazil are still uncertain.
