There are several types of environmental monitoring indicators applied by various institutions in Uganda. They fall under four broad categories, namely: Sector performance indicators, Cross-cutting issues indicators, and macro-economic indicators. Environmental monitoring indicators are measurements/statistical parameters that help to present a meaningful picture of what is happening with the environment. They are generally referred to as systems variables that express and communicate the quality of the environment and trends around it to a particular audience. They summarize some aspects of the state of environment, natural resources assets and related human activities. To be useful to the sustainable development context, environmental monitoring indicators should relate environmental aspects to socio-economic factors. Therefore such indicators are able to track environmental changes over time (i.e., identifying trends). They vary depending on the audience and the geographical, political or social context within which they are presented. They are based on several parameters including physical, chemical or biological measures associated with environmental quality or natural resources, processes, outcomes of particular interventions, and, activities or interventions themselves.
