Acroecology and the right to food 2011, para. 28

Paragraph

Paragraph text: Agroecology improves resilience to climate change. Climate change means more extreme weather-related events. The use of agroecological techniques can significantly cushion the negative impacts of such events, for resilience is strengthened by the use and promotion of agricultural biodiversity at ecosystem, farm system and farmer field levels, which is materialized by many agroecological approaches. Following Hurricane Mitch in 1998, a large-scale study on 180 communities of smallholders from southern to northern Nicaragua demonstrated that farming plots cropped with simple agroecological methods (including rock bunds or dikes, green manure, crop rotation and the incorporation of stubble, ditches, terraces, barriers, mulch, legumes, trees, plowing parallel to the slope, no-burn, live fences, and zero-tillage) had on average 40 per cent more topsoil, higher field moisture, less erosion and lower economic losses than control plots on conventional farms. On average, agroecological plots lost 18 per cent less arable land to landslides than conventional plots and had 69 per cent less gully erosion compared to conventional farms.
