India’s vulnerability to climate change impacts is profound since around 650 million Indians are dependent on rain-fed agriculture for their livelihoods; around 250 million Indians live along a 7500 km of coastline that is at high risk due to sea level rise and extreme weather events. Maximum number of business are situated near coastal areas and near river /other water bodies, many of the 10,000-odd Indian glaciers are receding at a rapid rate; and deforestation is happening (Garg et. al., 2015)

Key Messages: The urban population growth, inter-sectoral competition over water resources and climate change are expected roll out concurrently, amplifying water scarcity, energy and treatment costs and health issues in urban areas. Improving efficiency and reducing climate change related risks would be possible through integrated management of water, sewage, solid wastes and storm water management across household to city scales.

The climate-smart agriculture (CSA) concept reflects the ambition to improve the integration of agriculture development and climate responsiveness.
CSA technologies and practices present opportunities for addressing climate change challenges, as well as for promoting economic growth and development of the agriculture sector according to the authors of this country report on Sri Lanka.

According to this article, conservation agriculture is claimed to be a panacea for the problems of poor agricultural productivity and soil degradation in sub-Saharan Africa. Conservation agriculture offers the means that can prevent further destruction of precious soils, increase rainwater use efficiency and labour productivity, thereby ensuring higher and more stable yields.

This essay looks at climate change impacts on small island developing states (SIDS). It argues that climate change adaptation and mitigation strategies must be developed to cope with changes such as shifting precipitation patterns, increasing evapotranspiration and expanding saline intrusion into coastal aquifers and wells.

This is a documentary film on rainwater harvesting in Dewas, India. Following the complete exhaustion of groundwater, the farming communities began to suffer growing debts and losses. Food, fodder and drinking water became scarce. There seemed to be no hope until the seed of a new idea took root when one farmer went against the wishes of his family and dug a pond in his fields for collecting rainwater. In this awe-inspiring tale of innovation and courage, the district administration joined forces with the villagers to bring water to this arid land.

According to this study, a range of land management practices is available to help improve green water use efficiency. These practises can be classified according to their function. Hedgerow barriers and terraces can mitigate runoff; infiltration rates below hedgerows in Kenya were found to be three to eight times higher than where the crop was grown. Mulch that triggers soil fauna can improve water availability; mulching with straw from a local perennial grass in Burkina Faso doubled the water use efficiency from 1 kg mm-1 without fauna to 2 kg mm-1 with fauna.
