File:Number of agri-environmental policies and policy intensity index per country.webp

English: "a, A simple count of each country’s regulations, frameworks, payment programs and so on may offer hints into agri-environmental policy efforts, but ignores important policy characteristics such as ambition, targeting, stringency and enforcement. b, An alternative is to use a more complex metric by taking into account the general policy stringency and enforcement of these countries or the level of corruption they face. Arguably, agri-environmental policies are on average more effective when implemented by and in countries that generally have more stringent and better-enforced environmental policies and lower levels of corruption. By weighting the simple measure shown in a by these factors, an augmented measure can be obtained, as shown in b (Methods). EU member states have their own policies plus those of the EU."
