Sub-theme 1. Key issues of irrigation and drainage in balancing water, food, energy and ecology

 The world’s population is predicted to reach 9.1 billion by 2050. The uneven distribution of both water and population throughout the world pose a challenge in meeting the sharply growing water, food and energy demands. As per UN World Water Development Report, 2015, global water demand by 2050, is projected to increase by 55%, mainly due to growing demands from manufacturing, thermal electricity generation and domestic use. The withdrawals for agricultural sector accounting for roughly 70% of all freshwater withdrawals globally and over 90% in most of the world’s least-developed countries is already the largest and facing stiff completion due to growing requirement from other sectors. Further, water withdrawals for energy production, which currently account for 15% of the world’s total are expected to increase by 20% through 2035. In addition water demand from ecological sector is also increasing to maintain health of ecosystems. Water is used for agricultural production, forestry and fishery, along the entire agri-food supply chain, and it is used to produce or transport energy in different forms. At the same time, the food production and supply chain consumes about 30 percent of total energy consumed globally. Energy is required to produce, transport and distribute food as well as to extract, pump, lift, collect, transport and treat water. Cities, industry and other users, too, claim increasingly more water, energy and land resources, and at the same time, face problems of environmental degradation and in some cases, resources scarcity. So water, energy, food and ecology are inextricably linked. In order for sustainable development it is essential to maintain balance between water-food-energy and ecological services. However there are number of issues faced by irrigation and drainage sector such as diminishing water availability, deteriorating water quality, point and non-point pollution of water bodies, over exploitation of ground water, land degradation due to waterlogging and salinity, deteriorating irrigation and drainage infrastructure due to poor maintenance, poor water governance and service delivery, climate variability and impacts of climate change etc. in maintaining balance among water, food, energy and ecology sectors.

Keeping the above in view one of the sub-themes of the 2nd World Irrigation Forum (WIF2) has been identified as ‘Key issues of irrigation and drainage in balancing water, food, energy and ecology’ to facilitate discussion on various related topics covering Roles and efforts of the irrigation sector with respect to the World water issues; Drivers of policy, institutional, organisational and financial innovations for better stakeholder participation in irrigation and drainage services; Roles of water users, private sector, government organizations and civil society in management, operation and maintenance of irrigation and drainage systems; Innovations and extension under new irrigation and drainage performance and services requirements for national water and food security; Role of irrigation and drainage in forest management etc.
