How development may cause disasters

The side effects of well-meaning development efforts sometimes have disastrous consequences. Development projects implemented without taking into account existing environmental hazards may increase vulnerability to natural disasters. For example, projects designed to increase employment opportunities, and thus income, usually attract additional population growth. Low-income people may then have to seek housing in areas previously avoided, on hillsides or in floodplains. The costs of relief assistance after a landslide or flood can easily outweigh the benefits to the economy of more jobs. Similarly, development projects may lead to negative political consequences that increase the vulnerability to civil conflict.

Some types of development projects commence without fully assessing their impact on the environment. This can occur even in programmes resulting from a disaster, such as reconstruction projects that increase demand for wood to fortify houses. The resulting deforestation can then bring increased vulnerability to mudslides and possibly long-term environmental changes.

Development projects may even consciously force a choice between reducing disaster vulnerability and economic vulnerability. A project’s design may require a trade-off between the two and force a decision between the lesser of two evils.

Q. Can you describe how development can contribute to vulnerability based on the following examples of negative consequences?
