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.

Maharashtra is reeling under drought this year too, with the situation in Marathwada particularly bad. 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).

Study shows how rainfall and temperature affect variety of plants in major bio-geographic zones of India

New Delhi, July 9 (India Science Wire): India has a total geographical area of nearly 329 million hectares. The climate varies from the north to the south and east to west. However, in spite of this diversity, little is known about how climate affects the diversity of plants that grow in a particular area.

A study finds that selectively increasing coarse grains/millets in crop production can greatly help in reducing the negative impacts of climate shocks on future food production in India.

Crop production is highly influenced by the sensitivity of crops to variations in climate and can have major implications for food supply and rural livelihoods. The effects of climate change are increasing in India, where extreme rainfall events have become more frequent and spatially more variable. On the other hand, there has also been an increase in the severity and frequency of droughts.

Rapid urban growth, scarce water resources and a high risk of natural disasters pose serious challenges for Leh's urban planning and governance.

Across South Asia, small and medium-sized towns are rapidly expanding. Urbanisation has made inroads into the entire Himalayan region. Mountain urbanisation poses a need for assessments of emerging risks and vulnerabilities in environmentally sensitive regions. These areas are marked by population growth and migration from rural settlements as well as limited availability of suitable space for construction, often leading to building activities in landslide or flood-prone areas.
