Yet another Economist article that falls right in line with my PhD dissertation. One of us might be on to something.
Healthy ecosystems, such as forests, on or bordering agricultural land helps water and nutrient cycling, reducing the need for irrigation and chemical fertilizers. The enhanced biodiversity also acts as natural resistance to pests. The trick is paying farmers to keep forests on their land, compensating them for the loss of revenues from the crops that would have been planted on that land. These forests perform ecosystem services that greatly benefit society as a whole, economically and in terms of human and ecological health. Paying farmers helps to internalize those positive externalities.

In the war against climate change, peasants are in the front line
FOR people who see stopping deforestation as the quickest climate-change win, Copenhagen seemed a success. Although there is still work to be done on the initiative known as REDD (Reducing Emissions from Deforestation and Forest Degradation), the deal struck in Copenhagen made it into a real thing, not just an idea. The notion of reducing net deforestation to zero was not explicitly mentioned, but it looks much more credible than it did two years ago.
As well as giving heart to the protectors of trees, this outcome is encouraging for people whose focus is not on forests but on fields. Climate and agriculture matter to each other in several ways. On the downside, farming is a cause of deforestation, and also emits greenhouse gases in its own right—perhaps 14% of the global total. On the upside, agriculture can also dispose of heat-trapping gases, by increasing the carbon content of soils.
