Environmental degradation has been cited as one of four root causes of refugee flows, together with political instability economic tensions and ethnic conflict (UNHCR 1993).

This is leading to land degradation, especially in marginal areas, and habitat fragmentation. High population densities are putting enormous stress on the environment. Continued rapid economic growth and industrialization is likely to cause further environmental damage, with the region becoming more degraded, less forested, more polluted and less ecologically diverse in the future.

The IPAT equation, first devised in the 1970s, is a way of determining environmental degradation based on a multiple of factors. At its simplest, it describes how human impact on the environment (I) is a result of a multiplicative contribution of population (P), affluence (A) and technology (T).
Essay on Land Degradation and its Cause!

Natural hazards are excluded as a cause; however human activities can indirectly affect phenomena such as floods and bushfires.
