Despite the crippling effects of the recent economic slowdown on many industries, the organic agriculture sector not only sustained itself during this period but also showed signs of growth. "In 2009, organic farming was practiced on 37.2 million hectares worldwide, a 5.7 percent increase from 2008 and 150 percent increase since 2000," writes policy analyst E.L. Beck, in the latest Vital Signs Online release from the Worldwatch Institute.

The International Federation of Organic Agriculture Movements (IFOAM) defines organic agriculture as: "a production system that sustains the health of soils, ecosystems and people. It relies on ecological processes, biodiversity and cycles adapted to local conditions, rather than the use of inputs with adverse effects. Organic agriculture combines tradition, innovation and science to benefit the shared environment."

Although organic agriculture is practiced around the world, certified organic agriculture tends to be concentrated in wealthier countries. The Group of 20 (G20), comprising both developing and industrialized countries, is home to 89 percent of the global certified organic agricultural area. But nongovernmental organizations, including Slow Food International and ACDI/VOCA, are working with farmers to promote organic agriculture in developing countries as a means of bettering livelihoods and rejuvenating the land.

In western Tanzania, organic agroforestry practices have helped rehabilitate some 350,000 hectares of desert land over the span of two decades. And in Ethiopia, coffee farmers are learning how to protect wild coffee plants, fertilize them using organic compost, and process them in a manner that retains the quality of the crop, without damaging the environment.

Although the global organic market has shown growth in the past few years, the rate has slowed since 2000, and there are several challenges that impede large-scale expansion of organic practices. The price premium on organic foods, for example, may dissuade many consumers from buying organic products, despite the potential environmental, ethical, and health benefits these products provide.

Two other challenges are the lack of organic standards and the scarcity of equivalency agreements. An equivalency agreement between two countries acknowledges each other's organic standards and allows for a smooth flow of certified organic goods between the two countries. The Norwegian Agency for Development Cooperation finances the Global Organic Market Access (GOMA) project, which facilitates the trade of organic products by establishing organic standards and negotiating equivalency agreements, but more progress is needed in this area.
