New Delhi: Global warming could add up to 3.2 percentage points to food inflation every year in a decade’s time, and will affect the Global South more than high-income countries, according to a new international research. It also projected that the pressure on overall inflation could be 0.3-1.2 percentage points at the temperatures that the world will likely see in 2035. Researchers said the projections suggested that rising temperatures increase inflation all-year long in countries at low-latitudes, while in those at higher latitudes, inflation due to rising temperatures occurs only in summers.
Further, the authors, including those from Potsdam Institute for Climate Impact Research, Germany, estimated that heat extremes during the summer of 2022 raised food inflation in Europe by 0.67 per cent, an increase that could be amplified by 30-50 per cent under 2035 warming scenarios.

The researchers said that Africa and South America are likely to face a greater impact, but acknowledged the lack of detailed information in South East Asia on detailed information regarding price aggregates at monthly timescales. Their findings are published in the journal Communications Earth and Environment.
The researchers said,
Combining the uncertainty arising from empirical specification, emission scenario and range of climate model projections results in a range of potential pressures on food inflation of 0.92-3.23 p.p.p.y. (percentage points per year) by 2035, and of 0.32-1.18 p.p.p.y. for headline inflation, on average across the world.
These results therefore provide robust evidence that projected global warming would cause persistent upward exogenous pressures on inflation of considerable magnitudes already during the next few decades, independent of future emission trajectories and assuming ceteris paribus (all else being equal).
For the study, the researchers analysed monthly national consumer price indices and weather data across 121 countries between 1991-2020. They combined the results with projections from a physical climate model to estimate how rising temperatures impacted inflation between 2030 and 2060.

Even as climate change is likely to increase the price of food in the future, the authors suggested that mitigation of greenhouse gas emissions and technology-based adaptations could substantially limit this risk to the global economy.

NDTV – Dettol have been working towards a clean and healthy India since 2014 via the Banega Swachh India initiative, which in its Season 10 is helmed by Campaign Ambassador Ayushmann Khurrana. The campaign aims to highlight the inter-dependency of humans and the environment, and of humans on one another with the focus on One Health, One Planet, One Future – Leaving No One Behind. It stresses on the need to take care of, and consider, everyone’s health in India – especially vulnerable communities – the LGBTQ population, indigenous people, India’s different tribes, ethnic and linguistic minorities, people with disabilities, migrants, geographically remote populations, gender and sexual minorities. In a world post COVID-19 pandemic, the need for WASH (Water, Sanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign will continue to raise awareness on the same along with focussing on the importance of nutrition and healthcare for women and children, fight malnutrition, mental well-being, self-care, science and health, adolescent health & gender awareness. Along with the health of people, the campaign has realised the need to also take care of the health of the eco-system. Our environment is fragile due to human activity, which is not only over-exploiting available resources, but also generating immense pollution as a result of using and extracting those resources. The imbalance has also led to immense biodiversity loss that has caused one of the biggest threats to human survival – climate change. It has now been described as a “code red for humanity.” The campaign will continue to cover issues like air pollution, waste management, plastic ban, manual scavenging and sanitation workers and menstrual hygiene. Banega Swasth India will also be taking forward the dream of Swasth Bharat, the campaign feels that only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and the country can become a Swasth or healthy India.
