CA - FAO Roles and News

Conservation Agriculture (CA) is an approach to manage agro-ecosystems for improved and sustained productivity and food security while preserving and enhancing the resource base and the environment. CA is characterized by three linked principles:

1. Continuous minimum mechanical soil disturbance.
2. Permanent organic soil cover.
3. Diversification of crop species grown in sequences and/or associations.

Mechanical tillage is avoided or kept at an absolute minimum, and agrochemicals and organic or inorganic plant nutrients are applied optimally so as not to interfere with natural biological processes. Increasing organic matter on and in the soil is critical to maintaining a soil’s porosity, enhancing its moisture holding capacity and extending the availability of nutrients to crops.

CA facilitates good agronomic practices such as timely operations, and improves overall land husbandry for rain-fed and irrigated production. In conjunction with with the use of quality seeds, integrated pest, nutrient, weed and water management as well as sustainable mechanization approaches, CA is a base for intensified, market-driven sustainable agricultural production. It opens up options for integrated production, such as crops with livestock and trees.
