How has the focus on high yield crops affected India’s agricultural biodiversity and sustainability? suggest major to promote a more holistic approach to agriculture.

The forecast on high yield crop in India basically after the Green Revolution aimed to boost food security by increasing agricultural productivity.

Reduction in biodiversity: The emphasis on high yield crops like wheat and rice has led to a decline in traditional crop variety is reducing overall biodiversity.

Loss of traditional varieties: Many local drought Hello assistant and nutritionally superior crop such as millets have been abandoned in favour of high yielding varieties that led to the venue of such a highly valuable crop variety.

Increased chemical dependency: High ill crops have increased the Reliance on chemical fertilisers and pesticides leading to soil degradation and environmental pollution. 

Monoculture practices

The focus on the The staple crops have introduced the reliance on chemical fertilizer and pesticides leading to soil degradation and environmental pollution.

To promote holistic agriculture key measures introduced crop diversification to enhance biodiversity, promoting traditional agricultural practises and traditional crops like millers and adopting organic farming to reduce chemical use.

Agroforestry can integrate trees with crops for better file health and sustainability That will ensure productivity And will not harm the environment.

In this way you can write the answer for any competitive examination in proper manner in order to get the good marks and get selected in a respected completed exam search at UPSC and state PCs exam.
