Hinta and Dharta Villages (Rajasthan), 24.10.2024 (Loss and Damage Research Observatory): Tulsi Devi Bhatt, draped in an embellished purple sari and a full sleeve red kurti (top), navigates her way through the wheat fields in Hinta village in the western Indian state of Rajasthan’s Udaipur district. She is on her weekly mission to measure water level in the dug wells – the quantity of water is critical for the food security and livelihood of her community.

Hinta is part of the two multi-village, hard rock aquifer watersheds – the 6400-hectare Dharta watershed in Rajasthan and 5000-hectare Meghraj watershed in Gujarat, where MARVI – Managing Aquifer Recharge and Sustaining Groundwater Use through Village-level Intervention – project has been instrumental in enhancing groundwater recharge and availability.

Spearheaded by the Western Sydney University in Australia, working in collaboration with seven other partners in India and elsewhere, the MARVI project is aimed at empowering farmers like Tulsi with the knowledge and tools necessary for sustainable and equitable groundwater management in their villages.

Sydney, 11.12.20 (SciDev.Net): Researchers have developed a living plant-based sensor that can in real-time detect and monitor levels of arsenic, a highly toxic heavy metal, in the soil. Arsenic pollution is a major threat to humans and ecosystems in many Asia Pacific countries.

Arsenic contaminated water used for drinking, food preparation and irrigation of food crops poses the greatest threat to public health because the toxic chemical is naturally present at high levels in the groundwater of a number of countries, according to the World Health Organisation (WHO).

“Detecting arsenic level in the soil is important to ensure minimal contamination of our food chain. If we can have a convenient way to measure arsenic concentration in the soil in real time, we would be able to take preventive measures to keep arsenic level at the minimum, strengthening our food safety”, says Tedrick Thomas Salim Lew, a recent graduate student of the Massachusetts Institute of Technology (MIT) and co-lead author of the research published in Advanced Materials on 26th November 2020.
