Conservation Agriculture (CA) is defined as an approach to manage agro-ecosystems for improved and sustained productivity, increased profits and food security, while preserving and enhancing the resource base and the environment. It was founded because of the need to improve soil conservation and reduce practices associated with soil erosion and degradation in cropping systems such as shifting cultivation, while at the same time conserving resources (e.g. water, land, diversity of crops, and labour) and maintaining or enhancing crop yields. The use of the term Conservation Agriculture started in the early 2000s, and it builds on older concepts such as no-till, reduced tillage and conservation tillage. The use of such practices started far back in the 1930s in the United States of America, following a severe soil erosion crisis in the Mid-West which became known as the 'Great Dust Bowl'. From there, CA spread to the rest of the world, into South America, Australia, Europe, Asia and Africa. In Africa, the significant use of CA started in the 1970s in Zimbabwe, following the introduction of economic sanctions which forced farmers to use economic production techniques that minimised machinery wear and fuel use in cropping. More efforts were initiated for CA in the smallholder sector in Zimbabwe in the 1980s, from where it spread to Zambia and other countries in Africa.
