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.

Study shows land use changes responsible for higher temperatures

New Delhi, July 3 (India Science Wire): Warming induced by changes in land use and land cover is contributing to rise in temperature in Eastern India, according to a new study. 

Over three decades (1981-2010), the mean temperature in Odisha has recorded an increase of about 0.3 degree Celsius. The highest temperature rise of 0.9 degrees Celsius has been recorded during the years 2001 to 2010.

A study finds that farmers in south India continue to rely on borewells rather than investing in water conservation structures or demand management strategies to cope with droughts.

India is witnessing the second driest pre-monsoon season in the last 65 years. As the country eagerly eyes the monsoon clouds, the delay so far has now widened the rain deficit to 43%.

Study reveals women are central to both food production and preparation, as well as to domestic water provisioning.

The water sector remains male dominated at different scales, from engineers and technocrats responsible for designing irrigation systems, to upper caste and upper class men who decide on the location of canals, borewells, tanks, and other water systems at the grassroots level. While women are involved in the daily management of water for food production, especially on small farms, they have little say in water provisioning decisions.

A study found that intensification of croplands through replacement of forests can impact long term temperature trends.

The frequency and severity of heatwaves have risen considerably in India. Our cities are facing periods of ‘extreme’ weather as urbanization continues to modify the landscape. The temperature moderation provided by soil and vegetation is being substituted with heat-absorbent construction materials.

The effects of climate change are felt by the indigenous communities residing in the Himalayan region. How are they coping with these changes?

Mountain ecosystems are highly sensitive due to ecological fragility, geomorphologic instability but are blessed with vast eco biodiversity. Climate change impacts in the form of temperature rise, unpredictable and decreased rainfall, glacier melt, prolonged summers and short winters and changes in the seasonal cycle are happening at a more severe pace in the mountain areas making it more vulnerable to their impacts.
