Agriculture will massively impact the tropics

In a review article that has just appeared in the leading journal Trends in Ecology & Evolution, I teamed up with Jeff Sayer and Ken Cassman to assess the impacts of agriculture this century on tropical ecosystems and biodiversity.  It's quite a sweeping review with many important conclusions.

Among the biggest concerns are:

- Prospects for dramatic expansion of agriculture in Sub-Saharan Africa and South America

- Great uncertainty in the amount of land that will be converted to agriculture, in order to meet growing global food demands

-The prospects that biofuel production could also impact greatly on native ecosystems and also compete with agriculture

- The likelihood of massive environmental impacts on freshwater ecosystems and water supplies

- Profound challenges ahead in producing enough food to feed the world
