Farmers in several countries, including Canada, India, Kenya, Mozambique, and Sri Lanka have already initiated diversification as a response to climate change. Government policy in Kenya to promote crop diversification has included the removal of subsidies for some crops, encouraging land-use zoning and introducing differential land tax systems ...
Crop diversity or crop biodiversity is the variety and variability of crops, plants used in agriculture, including their genetic and phenotypic characteristics. It is a subset of a specific element of agricultural biodiversity .
Intercropping is a multiple cropping practice that involves the cultivation of two or more crops simultaneously on the same field, a form of polyculture. [1] [2] The most common goal of intercropping is to produce a greater yield on a given piece of land by making use of resources or ecological processes that would otherwise not be utilized by a single crop.
Conservation agriculture (CA) can be defined by a statement given by the Food and Agriculture Organization of the United Nations as "Conservation Agriculture (CA) is a farming system that can prevent losses of arable land while regenerating degraded lands.It promotes minimum soil disturbance (i.e. no-till farming), maintenance of a permanent soil cover, and diversification of plant species.
For crop plants, Nikolai Vavilov identified differing numbers of centers: three in 1924, five in 1926, six in 1929, seven in 1931, eight in 1935 and reduced to seven again in 1940. [ 4 ] [ 5 ] Vavilov argued that plants were not domesticated somewhere in the world at random, but that there were regions where domestication started.
Crop rotations also affect the timing and length of when a field is subject to fallow. [35] This is very important because depending on a particular region's climate, a field could be the most vulnerable to erosion when it is under fallow. Efficient fallow management is an essential part of reducing erosion in a crop rotation system.
An agricultural value chain is the integrated range of goods and services (value chain) necessary for an agricultural product to move from the producer to the final consumer. The concept has been used since the beginning of the millennium, primarily by those working in agricultural development in developing countries , although there is no ...
Diversification of agricultural products, such as fuelwood, medicinal plants, and multiple crops, increases income security [29] Increased food security and nutrition by restored soil fertility, crop diversity and resilience to weather shocks for food crops [29] Land restoration through reducing soil erosion and regulating water availability [26]
