26 65 Swiderska with Milligan, Kohli, Shrumm, Jonas, Hiemstra and Oliva Box 1: Biodiversity and culture Biodiversity refers to diverse crop and livestock varieties which provide food, nutrition and resilience to climate change, medicinal plants which provide healthcare, wild plants which provide foods and resources for plant breeding, and landscapes which provide vital ecosystem services such as water. Biodiversity also provides options for income generation (e.g. health foods, herbal medicines, natural products, seeds, eco-tourism). Biodiversity and culture are closely linked and inter-dependent. Cultural and spiritual values are enshrined in sacred bio-resources (e.g. coca leaves or special rice varieties used in rituals), ecosystems (e.g. sacred forests or mountains) and ancestral landscapes (e.g. sacred valleys). These values and beliefs help to sustain biodiversity and related traditional knowledge; while the use of diverse biological resources helps to sustain traditional knowledge and cultural values (Swiderska et al., 2009). Even where biodiversity is not lost, access to biodiversity resources may be restricted by intellectual property rights (e.g. commercial patents on seeds), or conservation initiatives such as strict protected areas. These pressures are making it ever harder for communities to secure their basic needs and continue their customary role and responsibilities as stewards of biodiversity. Indigenous peoples, who make up a third of the world’s poor and account for most of the world’s cultural diversity (5,000 different cultures), are under particular pressure. They often inhabit areas of high biological diversity and share a spiritual, cultural, social and economic relationship with their traditional lands. Their customary laws and practices reflect an attachment to land and a responsibility for preserving these lands for future generations. Yet, they often face marginalisation, displacement from their lands, territories and resources, denial of land rights, and adverse impacts from large-scale development (UN Permanent Forum on Indigenous Issues, 2010). This special issue of Participatory Learning and Action explores two important participatory tools that indigenous people and local communities can use to help defend their biocultural heritage against these pressures and threats, and assert their rights over resources and traditional knowledge. • Community protocols (CPs) are charters of rules and responsibilities in which communities set out their customary rights to natural resources and land, as recognised in customary, national and international laws. • Free, prior informed consent (FPIC) involves processes in which communities decide whether or not to allow projects affecting their land or resources to go ahead, and on what terms. In this overview article to the issue, written by the guest editors, we first set the scene, exploring CPs and FPIC further, emphasising the importance of community-level participatory processes in their development and highlighting the dangers of using them in a top-down, mechanistic way. We then consider recent changes in international law that have given these tools official support. Next we turn to the special issue itself, introducing the process we used to develop it, the objectives we hope to achieve, and outlining the structure of the issue. We finish by identifying key lessons and conclusions on how to effectively support FPIC/PIC and CPs to maximise positive impacts for biodiversity and livelihoods, drawing on the articles in this issue. Community protocols Many indigenous peoples and local communities have their own orally held rules and procedures, also known as protocols, to regulate conduct and interactions within their communities, with outsiders, and with the territories and areas on which they depend. These are often rooted in customary laws and rights which have sustained biodiversity and biocultural heritage for generations (Box 2). However, it is external actors (e.g. government agencies, researchers, companies or NGOs) who tend to define the terms
