Jagdambika Pal: Minimize food wastage for the sake of our planet and its people
Food loss and waste is a global concern that represents not just economic loss, but also the environmental and food security crisis. To put it into perspective, if food waste were a country, it would be the third-largest emitter of greenhouse gases in the world, surpassing the US and China.
Food waste accounts for nearly 8-10% of annual global greenhouse gas emissions, which is nearly three times the total emissions from the aviation sector. Decaying food emits methane, a greenhouse gas about 80 times more potent than carbon dioxide. Food production and its inputs emit climate-harming gases too.
Paradoxically, while nearly 20% of all food produced is wasted or lost, around 783 million people are grappling with hunger and about 150 million children under the age of five are suffering from stunted growth due to lack of proper nutrition.

Tackling food loss and waste is essential for us to address food and nutritional security challenges and significantly reduce greenhouse gas emissions. The pressing need to tackle the problem is articulated in India's commitment to Sustainable Development Goal (SDG) 12.3, which sets an ambitious target of reducing per capita global food waste at the retail and consumption levels and significantly cutting food loss along supply chains by 2030.
As estimated, even if just a quarter of all the food binned by households globally is edible, the equivalent of 1 billion meals of edible food is being wasted every single day by homes worldwide. The United Nations Environment Programme's Food Waste Index Report 2024 states that up to 17% of food wastage occurs between the retail and consumption levels.
This presents substantial opportunities for targeted intervention at these points, such as sustainable packaging solutions that may prolong the shelf-life of food, thereby providing a practical solution to the issue. We also need to improve infrastructure and include practices to preserve nutritional value and reduce wastage.

While only 21 countries had included food loss or waste reduction in their national climate plans (or Nationally Determined Contributions) by 2022, India has taken great strides to mitigate the same through coordinated measures at every stage of the supply chain by implementing schemes like the PM Kisan Sampada Yojana and production-linked incentive scheme for the food processing industry.
These government programmes focus on modernizing infrastructure, adopting advanced preservation and packaging technologies, reducing wastage and enhancing supply chain efficiency.
Programmes for the creation of backward and forward linkages and the creation of food processing capacities have been designed to drive infrastructural improvements that reduce spoilage and strengthen farm-to-market supply chains. Additionally, the Integrated Cold Chain and Value Addition Infrastructure Scheme provides fiscal support for upgradations with the aim of preserving nutritional value, increasing shelf life and raising food quality.

While addressing the crisis we face requires a collaborative approach in favour of a circular economy that integrates sustainable methods in all operations, it is equally important to ensure that food reaches consumers more efficiently. According to the Food and Agriculture Organization, up to 30-40% of food production in developing regions is lost before it even reaches the market, largely because of gaps in post-harvest storage, processing and transportation.
Food processing capabilities must be upgraded for food safety and shelf-life extension, among other objectives. Improved storage facilities and eco-friendly packaging are crucial to this endeavour, even as innovative means of food preservation need to be explored. Harnessing the potential of sustainable solutions like aseptic packaging with recyclable and eco-friendly materials would help reduce the ecological footprint of the processed food industry.
Generating awareness among consumers of responsible and eco-friendly practices through public-private partnerships and public campaigns can be of help in this exercise.
Successfully addressing the crisis of food loss and waste needs dedicated efforts by the entire ecosystem of producers, suppliers and consumers. Food loss and waste must be minimized across the supply chain from end to end. By doing so, countries and communities will benefit from increased food security, better access to healthy diets and reduced malnutrition, while decreasing their greenhouse gas footprints.

India, U.S. trade talks extended as deadline looms for interim deal, sources say
Trade talks between Indian and U.S. officials have been extended into next week as both sides seek consensus on tariff cuts in the farming and auto sectors, aiming to finalise an interim deal before a July 9 deadline, government sources said. A U.S. delegation led by senior officials from the Office of the United States Trade Representative (USTR) held two days of discussions in the national capital with trade officials headed by chief negotiator Rajesh Agrawal, the sources said. Also Read | India-U.S. trade deal in 'not too distant future': U.S. Commerce Secretary Lutnick "The two countries are actively engaged in focused discussions to facilitate greater market access, reduce tariff and non-tariff barriers, enhance supply chain resilience and integration," one Indian government official with direct knowledge of the talks, said. Negotiators, who had initially aimed to wrap up talks by Friday, will now continue discussions on Monday and Tuesday to resolve outstanding differences, a second official said. U.S. President Donald Trump and Prime Minister Narendra Modi had agreed in February to conclude a bilateral trade pact by fall 2025 and more than double trade to $500 billion by 2030. The current talks are part of efforts to hammer out a limited trade agreement that could lead the Trump administration to revoke 26% reciprocal tariffs on Indian goods - tariffs that have been paused along with those on several other U.S. trading partners for 90 days, the second official said. "Many Indian exporters have held back shipments to the U.S. in the last two weeks, fearing cargos may not reach before the July 9 deadline,' the official added. India's exports to the U.S. jumped nearly 28% year-on-year to $37.7 billion in the January–April period, driven by front-loading of shipments ahead of tariff hikes in April, while imports rose to $14.4 billion, widening the trade surplus in India's favour, according to US government data. Centre approved a licence for Elon Musk's Starlink to launch commercial operations, ignoring his public spat with Mr. Trump, Reuters reported on Friday. India is opposing U.S. demands to open up its agricultural and dairy markets, another Indian official said, citing the impact on millions of poor farmers who cannot compete with heavily subsidised American products. Indian officials have also made it clear New Delhi could pursue its complaint at the World Trade Organisation against the U.S. tariff hikes on steel and aluminium, while aiming to work out a bilateral agreement, the source added.

The link between leprosy and climate-change that we did not know about: an Indian story
When Sharadindu Ghosh* was young, he was taught not to speak about his father's leprosy. He, like many others, grew up in the lanes of Jamuria Leprosy Colony, in West Bengal, facing stigma and discrimination. Today, years after his father's passing and an endless struggle through poverty, Ghosh is an electrical supervisor and a mentor to local children. 'Among the uneducated population in India, people believe that this disease is given by God,' said Mervyn Basil, communications specialist at NGO Until No Leprosy Remains-India ( NLR-India). Leprosy was eliminated as a public health problem in India as per the World Health Organization's criteria of less than 1 case per 10,000 population, at the national level, in 2005. However now, experts say, it is quietly resurfacing, particularly in climate stressed States including West Bengal and Bihar. Floods, displacement and overcrowding have become frequent, leading to these States seeing the disease re-emerge in pockets. Also Read: Health Ministry announces new treatment regimen for leprosy The climate change-leprosy link India reported total 1,03,819 new leprosy cases for the year 2022-23 out of which grade 2 disability (G2D) cases were 2,363 (2.28%), amounting to 25% of the new G2D cases of the world, as per a statement given in the Lok Sabha in February 2024. Extreme weather events do not affect all communities equally, and people affected by leprosy often face risks far beyond those encountered by the general population. Research presented by James Pender at the 21st International Leprosy Congress in 2022 highlighted how climate -induced disasters disproportionately affect leprosy-affected communities. Floods cause the loss of homes, crops and in some cases even access to shelters. Those with leprosy-related disabilities are often left behind in evacuation efforts and many face discrimination at relief camps. In Bangladesh, for instance, over 4,000 people affected by leprosy were impacted by severe flooding in 2017 and many were denied basic disaster relief. India is ranked amongst the most climate-vulnerable nations globally and the intersection of disease, climate change and economic deprivation can further deepen the gaps. According to a report by the Leprosy Mission Trust India, States including Bihar, Jharkhand, Uttar Pradesh, Odisha and Chhattisgarh are also home to the largest proportion of people living in multidimensional poverty, meaning poverty that goes beyond money and wealth. 'Leprosy is a tropical disease and in tropical areas, there is a higher chance of this bacteria multiplying at a very rapid pace, and it's quite possible that it will multiply quickly,' said Mr. Basil. Eight districts across Bihar, West Bengal, Odisha and Maharashtra report a high climate vulnerability, widespread multidimensional poverty and endemic levels of leprosy prevalence. According to Bihar's State Water Resources department, 68.80 lakh hectares or over 76% of north and 73% of south Bihar are r egularly affected by floods. A total of 28 of the State's 38 districts are declared flood-prone. In Odisha, the situation may be worse: it remains one of India's most climate disrupted states. According to the Council on Energy, Environment and Water, 26 districts in Odisha are exposed to extreme climate events. The State has witnessed an increase in cyclonic events of late, with Koraput routinely facing floods that disrupt agricultural productivity and impact village residents who are primarily agricultural workers. With high risks of flood and drought, the State has a leprosy prevalence rate of 0.89. Chhattisgarh is also emerging as a key hotspot, with multiple districts like Bijapur, Kabirdham and Mahasamund having high prevalence rates of leprosy and deep rooted poverty. Kishanganj in Bhihar, Raigarh in Chhattisgarh and Nuapada in Odisha have reported leprosy prevalence rates above 3% coexisting with poverty levels that exceed 60% in some cases. Even in relatively better-off states like Maharashtra and West Bengal, vulnerability in clusters exists especially in tribal areas like Nandurbar and Jhargram. Triple jeopardy Shubhojit Goswami, senior programme manager at Leprosy Mission Trust India said: 'Our report does not claim or suggest that changes in climate patterns lead to leprosy transmission. But extreme climate events like floods, cyclones and droughts increase risk factors like malnutrition, limit access to clean water and poor hygiene which are known to contribute to leprosy spread' Displacement emerges as another key concern. When residents of rural areas face climate shocks like floods or droughts, they tend to migrate to urban areas. 'Many can only afford to live in overcrowded slums and high population density increases the transmission risk,' said Mr. Goswami. He cites the example of Shravasti district in Uttar Pradesh, where heavy floods in October 2022 came just months after a drought had already devastated agriculture. 'This kind of back-to-back climate shock is becoming the new normal,' he pointed out. Shravasti is a high-endemic district for leprosy where more than 70% of the population lives in multidimensional poverty. The need for interventions Urgent interventions by government and NGOs are needed. Three steps that Mr. Goswami states as urgent are: building community resilience alongise awareness programmes on climate-adaptive health behaviour; strengthening health systems in leprosy endemic districts to mitigate climate shocks as well as hyper-local climate and health risk assessments. A total of 30 districts across India are at the risk of 'triple jeopardy' i.e. the disease, climate change and poverty coexisting. 'These triple burdens often affect specific districts and not entire States,' said Mr. Goswami. Muzaffarpur in Bihar for instance, suffers from co-endemic diseases like leprosy and filariasis, and it floods every year. These districts should receive prioritised resources and support, he said. Districts such as Nandurbar in Maharashtra and Jhargram West Bengal have tribal populations living in relatively wealthier states and endemic leprosy still exists. 'People need to understand how both leprosy and climate interact, but this can only happen when investments in local health systems are capable of reading and reacting to climate data,' said Mr. Basil. 'Initiatives related to climate change have not been undertaken as yet as there is a lack of funding. As of now, no climate change organisation is actively working on leprosy-related impacts. Thematic donor support is a major problem as climate change itself is a new subject,' Mr. Basil adds. Reaching the last mile 'People affected by leprosy are often the last to receive medical care during disasters like floods and it is not always that they don't want to go to the hospital, it is the social stigma that affects their decisions. There exists a fear that they will be turned away or harassed by others at relief centers or hospitals,' said Mr. Basil. Climate change is causing cracks in our public health systems. The time to act is now, as leprosy is not going to disappear: it demands urgent interventions, visibility, and funding. *Name changed on request, to protect privacy (Aditya Ansh is an independent media reporter based in New Delhi.
