Comparing land sharing and land sparing for conservation in the UK

How can we maintain or increase food production without compromising wildlife and other ecosystem services?

Overview

Globally, agriculture is the greatest threat to wildlife. For many regions of the world, evidence suggests most species would fare least badly if food demand was met through high-yield farming combined with the protection of natural habitats (known as "land sparing"), as opposed to more wildlife-friendly, lower yielding farming ("land sharing").

The UK has a long history of agriculture. Many species of conservation concern are linked to low-intensity, traditional High Nature Value farming, whilst some sensitive species that prefer a land sparing system may already have been lost. There is therefore an urgent need to examine the trade-offs between food production, wildlife conservation and other ecosystem services (eg carbon storage and recreation).

Objectives

  • To measure the relationship between breeding abundance and agricultural yield for breeding bird species in The Fens and Salisbury Plain.
  • To develop realistic scenarios of land-use for these regions which maintain overall levels of food production.
  • To evaluate these food production scenarios for each breeding bird species.
  • To evaluate these food production scenarios for other ecosystem services, including carbon storage and human recreation.

Key Dates

  • April-July 2016: Breeding Bird Survey fieldwork
  • Sept 2016 to date: Landowner surveys

Progress

Bird survey data has been collated from several sources and has been supplemented with fieldwork conducted during the 2016 breeding season.

Landowner surveys are underway and we are in the process of estimating food production yields for each bird survey site.

Planned Work

We are combining bird survey data with landowner interviews in order to compare bird species abundance with estimates of agricultural production. This has involved some fieldwork (to supplement existing national breeding bird survey data, as well as to meet farmers and nature reserve managers to discuss food production), which will continue throughout the 2017 breeding season. 

We will also hold workshops with local stakeholders to ensure that our land-use scenarios are as realistic, relevant and useful as possible.
