  • The Food and Agriculture Organization (FAO) has flagged the growing practice of monoculture —cultivation of a single crop at a given area in food production around the world.

FAO Report

  1. FAO published its latest report The State of the World’s Biodiversity for Food and Agriculture 
  2. Of more than 6,000 plant species cultivated for food production, fewer than 200 contribute significantly to food production globally, regionally or nationally,according to FAO’s .
  3. Only 9 plant species account for almost two-thirds of total crop production.
  4. These are using large quantities of external inputs such as pesticides, mineral fertilizers and fossil fuels,” the report said.

The report lists drivers of change affecting biodiversity for food and agriculture, including:

  • Population growth and urbanization
  • Over-exploitation and over-harvesting
  • Changes in land and water use and management
  • Pests, diseases and invasive alien species
  • Climate change
  • Pollution and external inputs
  • Natural disasters
  • Markets, trade and the private sector

Various Factors

  1. The first factor contributor majorly towards monoculture as people move to cities they tend to depend more on purchased foods, citing the example of Ecuador.
  2. They often also tend to lose ties with rural areas and rural foods, and increasingly opt for processed foods rather than fresh foods.
  3. This pressures producers to continuously grow or keep only a limited range of species, breeds and varieties of crops, livestock, trees, fish, etc.
  4. Individual holdings as well as wider productive landscapes become more homogeneous in terms of their genetics and physical structure, the report added.

Impact of Mono Cropping

  1. Such changes often affect the resilience of production systems and their role in biodiversity.
  2. Private food standards adopted by supermarkets and consumers have pushed farmers towards particular varieties and management procedures.
  3. International markets particularly be restrictive for market entry effectively debar the entry into the market of minor crops from developing countries.
  4. The emphasis on meat-based diets and the use of a narrow range of major cereals (maize, wheat and rice) is growing.
  5. The report predicts that the demand for standardised foods can reduce the diversity of crops and animals.

The diverse the better

  1. If a single variety is widely grown, a pest or disease to which it lacks resistance can lead to a dramatic fall in production.
  2. Diversifying crop cultivation, on the other hand, reduces risk of economic shocks.
  3. Integrating intercrops, hedgerows or cover crops, particularly legumes, into a system can reduce drought stress by helping to conserve water in the soil profile and help to replenish depleted soil fertility.
  4. Also crop diversification including rotation and intercropping and the use of diverse forage plants in pastureland, can reduce pest damage and weed invasions.
  5. The growing exploitation of land and water sources was eating in to integrated aquaculture, which in turn was pushing farmers towards monoculture.

The need of the hour

  • New supply systems
  • Improved public-private partnerships.
