National environmental non-governmental organizations (ENGOs) registered in a country.
The data on registered national ENGOs comes from the archives of the International Union for Conservationof Nature (IUCN) for the time period 1973-2006 from 181 countries. While the IUCN covers most countries, it is an umbrella organization where membership is not mandatory and ENGOs do not have to register. As a result, some ENGOs that have not registered with the IUCN may have been omitted. Therefore the variable becomes a proxy for the political leverage of ENGOs.
Type of variable: Continuous
