Prospects of Nanotechnology for Enhancing Water and Nutrition Security

Abstract

In India and other developing countries water security and food and nutrition security are intricately connected. Developments in nanotechnology can have significant implications for water resources augmentation, conservation and use. A framework for assessment of the potential of nanotechnology applications for enhancing water security is developed. Water filtration, waste water treatment and remediation, monitoring water quality and soil moisture and irrigation systems are identified as key determinants of water security that have significant implications for food and nutrition security, which can be impacted by developments in nanotechnology. Using literature and patent data, a model to organise and map nanoresearch areas to the water security determinants is developed. The model is based on a specially designed database, which allows identification and prioritisation of nanotechnologies to enhance water security. The potential for commercialisation of some promising nanotechnologies is also assessed.
