摘要：Agriculture is a provider of food and, to a certain extent, public goods such as biodiversity and landscape, but it can also have negative impacts on natural assets such as biodiversity and water quality. In addition to implementing policies that target individual farmers, different approaches are needed to promote collective action. The literature review and three New Zealand case studies (Sustainable Farming Fund, East Coast Forestry Project and North Otago Irrigation Company) have identified some findings including benefits and barriers of collective action and key factors for its success. Collective action should be given serious consideration in addressing agri-environmental problems.
