Policy J/AL: Protecting the best agricultural land

Consultation runs from: 1 December 2025 9:00am - 30 January 2026 5:00pm

What this policy does

This policy sets out how development proposals affecting agricultural land and soils should be considered. 

Policy J/AL: Protecting the best agricultural land

1. Planning permission will not be granted for development which would lead to the irreversible loss of Grades 1, 2 or 3a agricultural land unless: 

  a. The land is allocated for development in the or a

  b. Sustainability considerations and the need for the development clearly outweigh the impacts of the loss of the economic and other benefits of the land, and the development cannot be located on areas of poorer quality land. 

2. Uses not involving substantial built development but which take agricultural land will be regarded as permanent unless restricted specifically by condition including reinstatement to its pre-development quality. 

3. When considering proposals for the change of use or diversification of farmland, particular consideration shall be given to the potential for impact upon Priority Species and Habitats.

Agricultural land classification (ALC) is a system used to assess and categorise land based on its suitability for agricultural use. There are five grades, with Grades 1, 2, and 3a regarded as the ‘best and most versatile’ agricultural land, which should therefore be protected. 

has a significant resource of good quality agricultural land. This is a valuable resource that needs to be protected. The sector is a key economic and environmental resource with the total farmed area of just under 72,000 hectares in 2024. 

Much of the best agricultural land lies around Cambridge and the larger settlements, which may be the most sustainable locations for future development. The need to identify and maintain a supply of land for development means there is pressure for development of agricultural land. 

Farmland is also an important biodiversity asset for . South Cambridgeshire being still a largely rural district has a large proportion of open farmland which has a variety of habitats on both high and low grade agricultural land. This provides an extensive biodiversity resource for the district. Due to the pressures of increasing land use and the past needs of intensive cultivation, the farmland of the district in places is under severe stress and this resource needs to be protected. 

Priority Species and Habitats are those that are identified within the list of priority habitats and species in England (‘Section 41 habitats and species’) and detailed more fully in the list of UK BAP priority habitats
