The dynamic knowledge society demands that knowledge and information centres develop resources and services to anticipate and serve the needs of society. There is a growing need for developing and disseminating knowledge resources pertaining to specific subject areas to enable easy access by focused user communities. Sustainable development is one such area that has generated much interest in the national as well as international arena. The Knowledge x-change for Sustainable Development (KxSD) was initiated at TERI with an aim to function as a knowledge exchange platform on issues concerning sustainable development. The paper focuses on features of the portal that facilitate stakeholders to access insights and resources to address key challenges in the developmental issues. KxSD focuses on three main dimensions of sustainable development -- policy imperatives, technology & innovations, and community partnership. The portal showcases research and innovative practices, knowledge resources and success stories targeted at policy-makers and the wider research community.
