Putting trees on farms fundamental to future agricultural development
Date:2/9/2011

ricultural lands now exceeds 30%.

"The transformation of agriculture into agroforestry is well under way across the globe," said Garrity. "And there are drivers, including climate change, that ensure that this transformation will accelerate in the coming years, since agricultural systems incorporating trees increase overall productivity and incomes in the face of more frequent droughts, and agroforestry systems provide much greater carbon offset opportunities than any other climate mitigation practice in agriculture."

In many countries, it is now quite clear that the future of forestry is on farms. In countries such as India, Kenya, and many others, the majority of the nation's wood is derived from farm-grown timber.

Practiced by farmers for millennia, agroforestry focuses on the wide range of working trees grown on farms and in rural landscapes. Among these are fertilizer trees for land regeneration, soil health and food security; fruit trees for nutrition; fodder trees that improve smallholder livestock production; timber and fuelwood trees for shelter and energy; medicinal trees to combat disease; and trees that produce gums, resins or latex products.

Reinventing agriculture

Evergreen Agriculture is a form of agroforestry that integrates trees with annual crops. "We see Evergreen Agriculture as nothing less than the radical, but entirely practical, pathway to a reinvention of agriculture," said Garrity. "It is a vision of a future in which much of our food crops will be grown under a full canopy of trees."

Combining fertilizer trees with conservation farming techniques is doubling and tripling cereal crop yields in many parts of the African continent. The nitrogen-fixing tree Faidherbia or Acacia albida, is increasing unfertilized maize yields in Malawi, Zambia, Tanzania, Ethiopia, and in numerous other countries. They are now being grown on millions of hectares of crop land throughout Niger, at densities o
