This guide is for local organisations (e.g. community-based organisations and trusted local non-governmental organisations) which are supporting Indigenous Peoples and local communities in their desire to assess the sustainability of natural resources on their lands (both terrestrial and marine) and implement activities to ensure that this use is sustainable, where necessary. It can also be used by Indigenous Peoples and by local community groups directly. In this guidance, we are looking at sustainability simply as making sure natural resources are used in a way that doesn’t decrease their amount, ensures nature can keep working properly, and aligns with community understandings about responsibilities to future generations.
