Question

Elaborate as to how biotechnology can be helpful in achieving sustainable agriculture.

Answer 1

Biotechnology can support sustainable agriculture by improving productivity while reducing pressure on natural resources and limiting harmful inputs.

1. Improved crop varieties: Breeding and biotechnology can produce crops with higher yield, improved nutritional quality and wider adaptability.

2. Resistance to pests and diseases: Resistant varieties, including Bt cotton, can reduce crop losses and the need for chemical pesticides.

3. Efficient propagation: Tissue culture rapidly multiplies selected plants and can provide disease-free planting material.

4. Biofortification: Crops with enhanced vitamins, minerals, protein or healthier fats can improve nutrition without requiring a greater area of farmland.

5. Biological pest control: Biopesticides and bioherbicides can help control harmful organisms while reducing reliance on persistent chemical pesticides.

6. Alternative protein: Single-cell protein can supplement human and animal diets and may reduce pressure on conventional agriculture; production using suitable wastes can also help reduce pollution.

Applied responsibly, biotechnology can improve food quantity and quality while helping conserve soil, water, biodiversity and other resources.
