Agroforestry is a concept of integrated land use that combines elements of agriculture and forestry in a sustainable production system. There are both ecological and economic interactions between the trees and crops and/or livestock elements on an agroforestry system. These interactions can lead to higher productivity compared to conventional systems, and provide a wide range of services including soil management, microclimate modification, weed control, natural fencing, carbon sequestration and nutrient recycling.
In its simplest form, agroforestry can be described as “growing trees on farms” and includes the integration, both ecologically and economically, of the woody elements that may already be present in agricultural landscapes, such as hedgerows, windbreaks, buffer zones, trees in pasture, and small woodlands. At a greater level of complexity are agroforestry systems that are fully integrated structured systems where standard trees, orchard trees and/or coppice systems are grown in rows between crops or pasture.
Eco-agroforestry integrates agroforestry and biodiversity– realising the full potential of agroforestry as a self-sustaining diverse production system that works within ecological cycles and supports ecosystem health.

30th June – 1st July. Meeting: “Organic Agroforestry: Eco-functional Intensification” The Organic Research Centre hosted the 2011 Annual Meeting of the Farm Woodland Forum at Whitehall Farm, Farcet and Wakelyns Agroforestry, Metfield.

Agroforestry questionnaire Eco-Agroforestry is a sustainable land-use sys-tem which has immense potential to help the UK adapt to future challenges by providing ecosystem ser-vices, sequestering carbon, and increasing resilience to climate change, whilst producing food, fuel and fibre. However there is currently little awareness of this amongst UK farmers and landowners. In fact, we wondered how much farmers use and value their existing woodlands, so we did a survey to find out. Sophie Lewis, who has been with us on an internship, organised the survey and reports the findings. The full report is held on Organic Eprints here.

Our focus is on promoting an eco-agroforestry approach that integrates agroforestry with organic principles to realise the full potential of agroforestry as a self-sustaining diverse production system that works within ecological cycles and actively supports ecosystem health.
Our research work aims to support the development of agroforestry into the mainstream; using the definition of "ecosystem services - ecological processes that sustain human well-being" as a framework, we will consider the potential of eco-agroforestry to deliver the four main categories of services:
- Provisioning services - the production of food, fuel and fibre, and genetic resources, biochemicals, natural medicines, pharmaceuticals, and ornamental resources
- Regulating resources - including air and water quality regulation, climate regulation, flood control, and pest regulation
- Supporting services - services that are necessary for the production of all other ecosystem services, including soil formation, photosynthesis, primary production, and nutrient cycling
- Cultural services - aesthetic, spiritual, and recreational benefits.
While many of these ecological processes need to be studied at the fine-scale, it will also identify how these processes impact at the farm-, landscape-, national- and global scale; scales at which farmers, policy-makers and society are involved.
