A new UN University report highlights the peril of irreversible tipping points for both people and the planet
Interconnected Disaster Risks Report 2023: The looming threat of irreversible tipping points Posted on 26 Oct, 2023 07:54 AM

A United Nations University report released this week finds that drastic changes are approaching if risks to our fundamental socioecological systems are not addressed.

The risk tipping point is when an ecosystem loses key species that are strongly connected, triggering cascading extinctions of dependent species, which can eventually lead to the collapse of an entire ecosystem. (Image: UNU)
Switching crops in India's food bowl benefits water sustainability
Farmers' input, subsidies, incentives, and promotion through PDS could enhance the adoption of alternative cereals. Future policy framing should consider subsidies, irrigation efficiency, yield gap, and technological improvements. Posted on 24 Oct, 2023 04:45 PM

India is the second-largest cereal exporter globally, making its cereal production vital for both domestic and international food security. Three major states in the Indo-Gangetic Plain (IGP) - Uttar Pradesh, Bihar, and West Bengal - account for 30% of India's total food production and are considered the food bowl of India.

Field visits are an exciting enterprise, especially as a young student who wishes to understand rural India. But they are also a complicated process of seeing and discerning, trying to figure out what is real and what is not.

Farmer’s willingness to pay for groundwater irrigation: The case of Uttar Pradesh
Is there a potential for introducing an organised groundwater irrigation market in Western Uttar Pradesh, where informal groundwater markets continue to thrive? Posted on 28 Sep, 2023 09:58 AM

Irrigated agriculture consumes the largest share of freshwater resources, including both surface water and groundwater. As high as 40 percent of irrigation is dependent on groundwater, accounting for 70 percent of the total groundwater extractions world over and this share is predicted to increase with climate change.

Rethinking India’s water and climate narrative in agriculture
What are the reasons behind the sluggish pace of technology adoption for solutions related to water and climate change? Posted on 28 Aug, 2023 07:31 PM

As I embarked on my agtech and water tour in India, I was surprised to experience such a diverse range of extreme climate in just one month. I traveled from drought-stricken landscapes in North India (early June 2023) to flood-ravaged regions while leaving the country (early July 2023) and encountered uneven weather patterns in between.

Changing crop types and water scarcity: The case of Marathwada
What are the reasons for enhancement of drought like conditions in Marathwada in recent years? A study provides answers. Posted on 27 Aug, 2023 04:57 AM

Marathwada is one of the most drought-prone regions of India and the increasing severity of droughts and their adverse impacts on socioeconomic conditions in the region have been of major concern in recent years. Majority of the area of Marathwada is under rain-fed agriculture and the summer monsoon rainfall is crucial for agricultural production in the region.
