Forest carbon payment programs like the proposed reducing emissions from deforestation and degradation (REDD) mechanism could put pressure on "wildlife-friendly" farming techniques by increasing the need to intensify agricultural production, warns a paper published this June in Conservation Biology.

The paper, written by Jaboury Ghazoul and Lian Pin Koh of ETH Zurich and myself in September 2009, posits that by increasing the opportunity cost of conversion of forest land for agriculture, REDD will potentially constrain the amount of land available to meet growing demand for food. Because organic agriculture and other biodiversity-friendly farming practices generally have lower yields than industrial agriculture, REDD will therefore encourage a shift toward from more productive forms of food production.

"Land sparing, that is intensive farming on a smaller area of land, may offer more hope for meeting agricultural demands at lower costs to biological diversity than wildlife-friendly farming," we write. "Because land productivity under intensive agriculture is high, the opportunity costs of REDD will rise, particularly as demand for commodities rises."

We cite the expected demand for rubber as an example.

By 2050 growth in car ownership may necessitate production of 164 million metric tons of natural rubber for the tires alone, which would require 54 million ha of land under intensive rubber production or 161 million ha under lower-yield agroforestry production. In other words, the acreage requirements for low-yield, "jungle rubber" holdings are three times greater than industrial plantations.

Of course REDD may improve the viability of agricultural production on degraded lands, potentially relieving some of the pressure to intensify agriculture. Nevertheless the amount of land needed to meet forecast demand for food, fuel, and fiber is immense: 400-500 million hectares of new plantations and croplands may well be needed by 2050, assuming a 2-3 percent annual improvement in yields, a rosy scenario given the marginal productivity of most degraded lands.

So what is the future of wildlife-friendly farming techniques in a land-constrained world where forests are increasing pit against human consumption? We don't pretend to know the answer.

While wildlife-friendly farming offers greater opportunities for carbon sequestration (potentially combining biodiversity and climate change mitigation goals), it suffers from lower yields than industrial approaches to food production, making meeting future demand from a hungrier and more populous humanity all the more challenging.
