Immediate or technical causes
Immediate or technical causes (sometimes known as primary causes) are usually the direct technical causes of the problem. They are predominantly tangible (e.g. enhanced nutrient inputs), and with distinct areas of impact (with the exception of causes such as atmospheric deposition or climate change). Immediate causes, usually being technical in nature are the most straightforward to quantify, prioritise and geographically locate using maps.
A few examples of immediate causes taken from existing TDA documents are shown Here.
