Agricultural biodiversity
In developing countries sustainable agricultural food production and security requires
the introduction of the agricultural biodiversity concept. International organizations,
supporting the Convention on Biological Diversity, recognize that agricultural
biodiversity is essential for global food production, livelihood security and sustainable
agricultural development. Agricultural biodiversity encompasses the variety and
variability of animals, plants and micro-organisms that sustain key functions of the
agro-ecosystem, its structure and processes for, and in support of, food production and
food security (FAO 1999b).
During the last three decades the understanding of agricultural biodiversity has
developed from the recognition of the importance of genetic diversity. This coincided
with the introduction of the sustainable agriculture and rural development concept, and
the need to integrate environmental and production goals. Several organizations, such
as the World Conservation Union (IUCN), have developed policies and programmes
for integrating nature conservation with agriculture since the early 1970s, especially in
Western Europe. This development of ideas culminated in the Earth Summit (UNCED)
in 1992. Subsequently, the Commission for Plant Genetic Resources (CPGR) was
renamed the Commission for Genetic Resources for Food and Agriculture (CGRFA)
in order to reflect its expanded mandate to include forest, animal, fish and other
genetic resources, including bacteria and soil biota essential for food and agriculture.
Even though the commission still has a genetic and species scope, the focus now is on
developing the agro-ecosystem approach.
There is need for an integrated and holistic approach, linking the genetics of species
to the farm and the agro-ecosystem. Agricultural biodiversity is a prerequisite for
a sustainable agro-ecosystem as it promotes sustainable production of agricultural
products at all types and levels of intensity; enhances biological resources that support
sustainable production; and supports ecological and social services linked with
environmental protection.
