OECD Compendium of Agri-environmental Indicators

image of OECD Compendium of Agri-environmental Indicators

Agriculture can have significant impacts on the environment as it uses on average over 40% of water and land resources in OECD countries. The impacts occur on and off farm, including both pollution and degradation of soil, water and air. But agriculture also supplies ecosystem services, such as biodiversity, provides a sink for greenhouse gases, and contributes to flood control and the aesthetic value of landscapes.

This compendium updates the data issued in Environmental Performance of Agriculture at a Glance and provides comprehensive data and analysis on the environmental performance of agriculture in OECD countries since 1990, covering soil, water, air and biodiversity and looking at recent policy developments in all 34 OECD countries.

Water quality: Nitrates, phosphorus and pesticides

This chapter reviews the environmental performances of agriculture in OECD countries related to water quality. It provides a description of the policy context (issues and main challenges), definitions for the agri-environmental indicators presented, and elements related to concepts, interpretations, links to other indicators, as well as measurability and data quality. The chapter then describes the main trends of the agri-environmental indicators, using available data covering the period 1990-2010 and based on a set of tables and figures.
