Food, water, and energy security in South Asia: A nexus perspective from the Hindu Kush Himalayan region

By Golam Rasul. - With limited land resources, inadequate energy supply, and growing water stress, South Asia faces the challenge of providing enough water and energy to grow enough food for the burgeoning population. Using secondary data from diverse sources, this paper explores the food, water, and energy nexus from a regional dimension, emphasizing the role of Hindu Kush Himalayan (HKH) ecosystem services in sustaining food, water, and energy security downstream. The analysis reveals that the issues and challenges in the food, water, and energy sectors are interwoven in many complex ways and cannot be managed effectively without cross-sectoral integration. The most distinctive feature of the nexus in South Asia is the high degree of dependency of downstream communities on upstream ecosystem services for dry-season water for irrigation and hydropower, drinking water, and soil fertility and nutrients. This finding suggests that along with cross-sectoral integration to improve the resource-use efficiency and productivity of the three sectors, regional integration between upstream and downstream areas is critical in food, water, and energy security. Within the nexus approach in South Asia, equal attention should be paid to management of HKH ecosystems–especially the watersheds, catchments, and headwaters of river systems–and to tapping the potential of collaborative gains in water, hydropower, and other ecosystem services through coordination across HKH countries.

Securing the Future of India’s “Water, energy and food”

This paper provides an initial, formal analysis for the design of an Indian food procurement system that considers climate driven variations in renewable water supply, the needs for groundwater pumping, varying regional productivity of crops and farm level economics, assuming that the food security goals are to be met while keeping current procurement prices fixed for each crop, and maximizing net aggregate farm income from the procurement system. The results suggest that net farm revenue could be doubled while eliminating the need for irrigation to meet the food requirements.

Conference Proceedings

Balancing Economic Growth and Environmental Sustainability: Focusing on Food-Water-Energy Nexus

A major international conference was held by CEP-BCI in February 2012. The conference benchmarked GMS economic growth between 2001 and 2010 and its impact on environmental and social development as well as provided an outlook for the next decade. Topics discussed included known and emerging economic, environmental, and climate change challenges in the context of food, water and energy security, and participants charted out key strategic thrusts for the coming decade. More than 233 delegates, including senior government officials from the GMS countries, private sector representatives and development partners attended. The conference outcomes have provided important inputs to the GMS program in general, and CEP-BCI Phase II in particular. During the next decade, emphasis will need to be placed on the management of food, water and energy resources in the GMS, which requires a careful balance of economic and environmental interests and better management of natural resources.

Strategic Analysis Paper

The Food, Energy and Water Nexus (FEW) and Gross National Happiness in Bhutan

The complex interplay of food, energy, and water demand and supply poses numerous policy challenges, especially in the context of expanding population sizes, rising standards of living, and resource management constraints due to sustainable environmental practices.1 Bhutan provides an interesting illustration of how these issues can be addressed holistically, in a relatively socially responsible, economically beneficial and environmentally sustainable way.

Contribution of Himalayan Ecosystems to Water, Energy, and Food Security in South Asia: A nexus approach

In the face of climatic and other socioeconomic changes, most South Asian countries having large and growing population, limited land resources, and increasing water stress face a common challenge of how to grow more food with the same or less land, less water, and increased energy prices. This concept paper seeks deeper understanding of the interlinkages among water, energy, and food, which is crucial to formulate cross-sectoral policies for more resilient and adaptable societies. In South Asia, such a nexus approach inevitably needs to take Himalayan ecosystem services into account. Rice and wheat, the staple foods in South Asia, require huge amounts of both water and energy. The Indus-Ganges-Brahmaputra plain - the sub-region’s grain basket and one of the world’s largest areas of irrigated agriculture - depends in large part on the Himalayan mountain system as a source of both surface and groundwater for irrigation; as a source of hydropower; and as a regulator of climate and a repository of agro-biodiversity. To sustain these services and to ensure both upstream and downstream food, water, and energy security in South Asia, policies and strategies must therefore promote improved management of Himalayan watersheds, forests, wetlands, and rangelands. Recommended measures include support to restoration of natural water storage capacity; development of climate smart, environmentally and socially sound water infrastructure; adequate investment for natural resource management; and incentives to mountain communities for managing Himalayan ecosystems.

Thirsty Crops

Freshwater withdrawals have doubled every 30 years in last 100 years, about 4000 km2 per year at present. In India 80% of the surface water is utilized for agriculture. The WWF India`s “thirsty crop” project aims to reduce the impact of water intensive and polluting crops thereby maintaining sustainable fresh water habitats to support both biodiversity and livelihood.

Everything is a “Nexus”

Food, water, energy, and health form a nexus of interrelated factors. Food worriers see the long term curves of food supply and creeping demand closing in on each other. Most figure that a crisis will hit in a weather nexus when several major crop regions have a down year at once.

The world is closer to a food crisis than most people realise

Unless we move quickly to adopt new population, energy, and water policies, the goal of eradicating hunger will remain just that. Time is running out. The world may be much closer to an unmanageable food shortage – replete with soaring food prices, spreading food unrest, and ultimately political instability– than most people realise.

The Water-Energy-Food Security Challenge: America As The Global Savior?

Can the world support the aspirations for food and energy of the 7 billion people that now inhabit it? Will we meet the needs of the additional 2 billion people that we expect will be here by 2050? More than ever, the answers to these questions depend on how wisely we use the world’s fresh water resources — to both meet our own needs and to sustain the basic water requirements of all life that inhabits our blue planet.
