The FAO State of Agriculture report (2019) estimates that around 14 percent of food produced is lost between harvest and retail, while an estimated 17 percent of total global food production is wasted (11 percent in households, 5 percent in the foodservice, and 2 percent in retail) globally.5
India ranks 94th out of 107 countries on the 2020 Global Hunger Index. Nearly 40 percent of the food produced in India is wasted every year due to fragmented food systems and inefficient supply chains — a figure estimated by the Food and Agricultural Organisation (FAO). A survey conducted by ICAR-
Central Institute of Post-Harvest Engineering and Technology (CIPHET) in 2013-14, revealed the estimated economic value of post-harvest losses was Rs926.51 billion in 2014, which was 0.6% of the country’s gross domestic product (GDP).1
What constitutes food loss and food waste?
All the crop and livestock human-edible commodity quantities that, directly or indirectly, completely exit the post-harvest/slaughter production/supply chain by being discarded, incinerated, or otherwise, and do not re-enter in any other utilization (such as animal feed, industrial use, etc.), up to, and excluding, the retail level collectively constitute food loss.
Food waste is defined as food and associated inedible parts removed from the human food supply chain in the following sectors: manufacturing of food products (under certain circumstances); food/grocery retail; food service; and households.
Implications of food loss and waste
● Environmental impact
Food loss and waste represent wastage of the water, land, energy, and other natural resources used to produce food. Food loss and waste are responsible for about 8% of global greenhouse gas (GHG) emissions. The volume of water used to produce lost or wasted food is equivalent to three times the volume of Lake Geneva. Nearly 30% of the world’s agricultural land is currently occupied to produce food that is ultimately never consumed. If food use and distribution is better managed, 14% of all GHG emissions from agriculture could be avoided by 2050.3
● Economic impacts on farmers & Social Impact
The safe and nutritious food that is lost, discarded, and wasted can feed up to 2 billion people, or more than double the number of undernourished in the world. If we save one-fourth of the food currently lost or wasted, we can feed 870 million hungry people.
Food loss occurs at various stages and levels some of which are:
Food waste may occur in one or more than the below levels-
The solutions to stem food loss and waste include:
● applying innovation for marketing or retractable mobile food processing systems,
● Government incentives to bolster private-sector food loss and waste action and collaboration across supply chains,
● investments in training, technology, and innovation, including for small-scale producers,
● better food packaging and relaxing on regulations and standards on aesthetic requirements for fruit and vegetables; behaviours that value and make the most of food at home,
● redistributing safe surplus food to those in need through food banks; facilitating farmer’s access to consumers and shorter value chains through farmers markets and rural-urban linkages,
● investing more to strengthen infrastructure and logistics, including sustainable cold chains and cooling technologies.
A Ray of Hope
S4S Technologies (science for society technologies) is one of the organizations trying to overcome food loss through innovation and technology. It is a modern start-up that helps farmers preserve their produce, become self-dependent, and find novel ways to sell their produce directly. Nidhi Pant, the co-founder at S4S technologies mentions that "our goal is first to prevent the food wastage happening at the farm level and also move farmers out of poverty. We are also scaling this up rapidly to reach 3000 women entrepreneurs."
Nidhi Pant is also the recipient of the Women Transforming India award by Niti Ayog in collaboration with the UN and has also been listed on Forbes 30, under 30 Asia. Listen to her story unfolding covering aspects like the reason for her interest in science, the birth of S4S Technologies, her perspectives on overcoming gender disparity within the realm of science and technology, the need for more role models for women, and the future of sustainable methods to prevent food waste.
