Efforts towards sustainability in any field are built on processes for communicating, learning, and sharing knowledge, engaging people in their multiple roles as individuals, and as members of communities and organizations. The Learning for Sustainability website portal (formerly NRM-changelinks) is designed for those wanting to improve such collaborative initiatives. The site highlights the wide range of networks, forums, processes and social skills needed to support constructive collaboration. The site structure shows how these elements can work together, and collectively brings links to several hundred annotated on-line resources together in one easy to access site.
