According to the United Nations Development Programme, nearly 40% of the food produced in India is wasted from the farm to the fork. That translates to roughly ₹250 crore per day or more than ₹90,000 crore per year. These losses result in a lower income for the producer (farmer) and increases the cost for consumers. But the most significant impact is that it challenges our overall food security, as we need to feed our ever-growing population. It is estimated that saving even one-fourth of the food currently lost or wasted would be enough to feed the hungry people in India.
Food loss happens very differently in developed and developing countries. In developed countries, food waste and loss occurs largely at the end of the chain. It is estimated that in the United States, 31% of food loss occurs either at retail due to dumping of over-ordered or spoilt food or at the consumer end when they buy or cook more than they need and choose to throw out the extras. However, in developing countries like ours, most of the food loss occurs at the beginning of the chain. It occurs after harvest or during transit from the farm to the large consumption areas based in urban markets. This can be attributed to poor storage, cooling, and transport infrastructure.
Critical Elements in the Cold Chain
There are four critical elements of the cold chain that need to be implemented from the farmer to the consumer.
1. Post-harvest chilling and storage of produce in the village itself
2. Chilled transport of the produce from the village to the processing/ aggregation centre
3. Chilled transport of the finished product to the market

EMISSIONS CONTROL IN THERMAL POWER STATIONS: A Long Road to Cross
In this article, Raghav Pachouri brings out the current situation and the challenges confronting us regarding emissions control in thermal power stations (TPSs) in India. While analysing the impact of the power sector on air pollution levels, he highlights the current status of compliance in India (especially Delhi-NCR and critically polluted areas) till June 2020 after revised emission norms for TPSs came into effect on December 7, 2015. He also dwells on the major roadblocks in the timely compliance of emission norms and also offers a few solutions.
Managing Air pollution From Crop Burning
The perils of crop-residue burning contribute to major environmental degradation. In this article, TCA Avni and Sunil Dhingra discuss how the practice of stubble burning is responsible for poor air quality and loss of agricultural biodiversity. They highlight the importance of managing paddy residue and offer sustainable solutions, incentives, and alternatives to crop burning.
