Monsoon rains provide relief from the sweltering summer heat conditions, replenish depleted profile moisture to breathe new life in soils. With appropriate management of rain water, Indian summer monsoons boost the level of ‘reservoir of life’. Our inability to manage spatial and temporal rainfall variation features of deficit and excess rainfall episodes and their interactions with soil variability is a major cause of uncertainty in agricultural production. In the past, entire focus of national efforts was on rainwater harvesting, storage and distribution through canal networks and greater reliance on ground water pumping to meet immediate crop water demands. These approaches have resulted in wide spread problems of natural resource fatigue and unsustainable water supplies. This paper analyses the complexities of climate change-land degradation-food security nexus and suggests the need for adopting alternate approaches emphasising on in situ conservation of rain water and its efficient use such as to reverse the processes that contribute to land degradation in specific landscapes.

With the possibility of the Water-Energy-Food (WEF) Nexus since a long time back, overlooked interlinkages between WEF are getting the chance to be indisputable. Nonetheless, agriculture is responsible for quite a bit of fresh water over-use. Food production further effects the water and energy sectors through degradation of land, changes in overflow, disturbance of groundwater release, water quality, accessibility of water and land for different purposes. The responsibilities of this unparalleled issue include particular parts of the organization around the Nexus. While a couple of papers try to conceptualize the Nexus-Governance, this phenomenal report gives a rich combination of work for further WEF-Nexus ponders and integrative methodologies.
