Bioresources are mostly located in rural and coastal areas (forests, fish, algae, farm by-products) but appear also as e.g. orga nic waste. Their productivity a nd accessibil -ity differ between localities, given variation in natural conditions and the management of ownership and use. However advanced are the technologies involved, the biological raw materials used stem from - and impact on - land, water and sea-based bioresources. Alternative and competing uses touch on human rights and common property.
