Katalysis: helping Andean farmers adapt to climate change
The Andes have daily (rather than seasonal) temperature extremes, unpre- dictable weather from one year to the next, and a myriad of environmental niches scattered across the elevations. To survive in such an adverse environment, highland farming evolved to be robust, with complex soil and water management, a rich diversity of crops and varieties, and planting schemes adapted to altitude. Much of the work is done through collective labour and sharecropping.
