A study develops a peri-urban and rurban water and sanitation index for Pune.

Drinking water programs in India treat urban and rural areas separately, generally neglecting the special characteristics of settlements referred to as peri-urban – those on the outskirts or peripheries of urban areas, or “rurban” settlements i.e. rural areas with urban facilities.

A study shows how the open space on the western bank of the Sabarmati river in Ahmedabad acts as a heat sink.

A study published in the Journal of Remote Sensing and Space Sciences, analyzing the cooling effect of the city of Ahmedabad’s water bodies, has thrown up some interesting findings. The east bank of the Sabarmati river, which flows through Ahmedabad, was found to be significantly cooler than the west bank, witnessing a greater drop in temperature even during summer. The study provides direct evidence of how water bodies affect temperature variations.

Mobile agri-advisory services provide timely and relevant advice to farmers. But do they translate to practice in the field?

Agricultural extension and advisory services facilitate the transfer of knowledge, information, improved technologies and practices to farmers, farmer organizations and market actors. Research has shown positive effects of extension access when it came to knowledge, adoption, productivity, and economic returns for farmers. The high cost associated with face-to-face extension constrains effective service delivery to farmers, who are often widely distributed spatially.

Mangroves are carbon-dense ecosystems that can play an important role in carbon storage, study suggests.

Straddling land and sea and swarming with life, mangroves are key to healthy coastal ecosystems. They are recognised for their role as storm barriers, protecting coastal areas from flooding and erosion by dissipating the energy of huge waves. They act as nurseries for fish, help filter river water of pollutants and trap excess sediment before it reaches the ocean. Increasingly, mangrove protection and restoration is being acknowledged as a viable option for mitigating the effects of growing greenhouse gas emissions worldwide.

A research paper argues that quick fix solutions to drought management will not work unless they are backed up by proper planning, implementation, monitoring and regulation of water use.

As high as twenty four out of thirty six districts in the state are facing deficient monsoons and about 4,920 villages and 10,506 hamlets are now completely dependent on water tankers for drinking water.

A study in Telangana argues that farmers’ expertise is important while assessing the severity of soil erosion.

Regionally and globally, soil erosion is a major contributor to total land degradation. Its impact is more pronounced in rainfed areas and it is a major threat to agriculture in India, with a significant economic cost amounting to about 0.35% of GDP in 2014-15 as per estimates by TERI (2018).

A study finds that hydropower organisations in India continue to maintain a culture of hierarchy, follow masculine norms and are insensitive to the needs of women and the marginalised.

Large dams, back in the game?

Recent years are seeing the re-emergence of large dams as sources of hydropower generation in global development policy. Large dams are being propagated as clean, green, climate-mitigating and a major source of renewable energy in emerging markets in the Global South.
