Human Effects on Water Resources

Respond to the following based on your review and any other research into the issue you care to do. You must reply to the assignment using the memo format referenced in your course syllabus. I will review your response to the issue(s) and then provide you feedback on your assignment response. In order to manage our water resources more efficiently we need a better assessment of what the current demands are and which of these are essential to the populations’ needs (health and commerce).

Item A – What are some of the key areas that we should assess for population demands on water resources? How do we balance the need to build water sources (dam and reservoirs) with the environmental impact and the need to balance the productivity of a specific ecosystem and the maintenance value of the ecosystem incurred as part of the development of the water reserve?

Item B –How do water managers identify water resources effectively for human use, but do so in such a way that human use of the resource is not a disproportionate environmental impact?

The techniques reflect the extent to which the goods and services provided by water resources touch on the welfare of society either as direct determinants of individuals’ well-being (e.g. as consumer goods) or via production processes (e.g. as intermediate goods). They are grouped here according to whether the techniques rely on observed market behaviour to infer users’ value of water resource functions (indirect techniques), or on whether they use survey methods to obtain valuation information directly from households (direct techniques).

b) The focus on economic efficiency as the primary objective in the development and allocation of water resources is because of its importance as a social objective; efficiency values having viable meaning in resolving conflicts and assessing the opportunity costs of pursuing alternative uses (Young, 1996). Although economically efficient allocation of irrigation water is rarely attained in practice, analysis of economic efficiency provides a useful point of reference for understanding causes of inefficient allocation and mechanisms for improving the overall economic performance of irrigated production.
