Reconciling productivity with protection of the environment: is temperate agroforestry the answer?

摘要: Meeting the needs for a growing world population calls multifunctional land use, which can meet multiple demands of food and fuel production, environmental biodiversity protection, has capacity adaptation or resilience to climate change. Agroforestry, land-use system that integrates trees shrubs with crops and/or livestock been identified by International Assessment Agricultural Knowledge, Science Technology Development (IAASTD) as ‘win–win’ approach balances production commodities (food, feed, fuel, fiber, etc.) non-commodity outputs such protection cultural landscape amenities. Evidence is now coming light supports promotion agroforestry in temperate developed countries sustainable alternative highly industrialized agricultural model its associated negative externalities. This paper reviews this evidence within ‘ecosystem services’ framework evaluate part working regions. Establishing on help mitigate many impacts agriculture, example regulating soil, water air quality, supporting biodiversity, reducing inputs natural regulation pests more efficient nutrient cycling, modifying local global climates. The challenge lies promoting adoption mainstream use through research, dissemination information policy changes.
