Why I do
Science?

Having been born and raised in India, living in various parts of the country and later pursuing research abroad, I’ve been fortunate to experience a rich diversity of cultures and perspectives along my journey. Through these experiences, I became aware of how our everyday actions—from the food we consume to the vehicles we drive—influence Earth systems. Often without realizing it, we each play a role in shaping environmental processes, the effects of which can ripple across societies and contribute to climate change, biodiversity loss, food and water insecurity.

At the same time, we live in a remarkable era of technological progress, where innovation offers new opportunities to support a more sustainable future. I’ve long been fascinated by the remote sensing advances, especially in understanding our changing planet.

In my research, I try to harness these innovations not only to gather insights into (socio-ecological) Earth system dynamics, with the aim to bridge the gap between science, policy and action. Through my research, I aspire to contribute toward building a sustainable future, one step at a time.

Recent
publications

My recent publications highlight how food production and consumption drive deforestation. These activities can significantly disrupt Earth's system functions by altering the carbon and water cycles.

Such changes carry the potential for catastrophic impacts, including the loss of a significant portion of our rainforests, necessary for maintaining a sustainable environment in the future.

Mapping impacts,
supporting stewardship.

With the ambition to make a positive impact on society,
keeping oneself motivated is quite crucial.

Concerning facts about Earth system!

Carbon dioxide (CO2) emissions

Annual report from NOAA’s Global Monitoring Lab

As of April 2025, atmospheric carbon dioxide levels have reached around 430 parts per million (ppm). That’s astonishing, considering CO₂ levels never rose above 300 ppm in the last 800,000 years—until the industrial age began.

Temperature

Study by Xu et al. (2020) 'Future of the human climate niche' published in PNAS

Currently, only about 0.8% of the Earth’s land surface experiences mean annual temperatures above 29°C—conditions considered largely uninhabitable for humans. A study projected that, under a high-emissions scenario, such extreme heat could spread to up to 19% of the planet’s land area by 2070, potentially affecting around 3 billion people.

Habitable land

Our World In Data

Nearly 44% of the world’s habitable land (i.e., fit for livelihood) is used for agriculture. Of this, around one-third is devoted to croplands, while the remaining two-thirds are used as grazing land for livestock.

Forest

World Wide Fund for Nature

Forests once covered just under half of the Earth’s habitable land. Today, we are losing approximately 100,000 square kilometers of forest each year. Globally, up to 80% of deforestation is driven by the expansion of agricultural land—primarily for crops and livestock.

Food

FAO’s 2023 'State of Food Security and Nutrition in the World' report

Despite the continued expansion of agricultural land to meet global food demand, the number of undernourished people has increased by over 100 million in the past decade. Projections suggest this number could rise by another 100 million by 2030 if current trends persist.

Water

Study published by Mekonnen & Hoekstra (2016) in Science Advances

Around 4 billion people—nearly two-thirds of the global population—experience severe water scarcity for at least one month each year. By as early as 2025, half of the world’s population could be living in areas facing water stress or scarcity.

Finance

Climate Policy Initiative

Climate finance reached nearly $1.3 trillion in 2021–22, a significant increase from $364 billion in 2011–12. However, under a pathway consistent with limiting global warming to 1.5°C, analysts project that around $9 trillion will be needed annually by 2030 for climate mitigation and adaptation. This figure is projected to rise to over $10 trillion per year between 2031 and 2050.
