Improved Fertilizing Practices On The Peel-Harvey Catchment, P T. Arkell

Journal of the Department of Agriculture, Western Australia, Series 4

Broad-acre farmers in the Peel-Harvey catchment have met a challange and achieved a great deal since the fertilizer extension programme started in 1983.

The main objective of the extension programme has been to ensure that every year three-quarters of the farmers make economically and technically sound fertilizer decisions, thus causing a minimum amount of phosphorus to enter the waterways of the Peel-Harvey estuarine system.

Executive Summary

Biological diversity refers to the variety and variability among living organisms and the ecological complexes in which they occur. Diversity can be defined as the number of different items and their relative frequency. For biological diversity, these items are organized at many levels, ranging from complete ecosystems to the chemical structures that are the molecular basis of heredity. Thus, the term encompasses different ecosystems, species, genes, and their relative abundance (OTA, 1987).

There is an ongoing, unprecedented loss of the variety as well as absolute numbers of organisms-from the smallest microorganism to the largest and most spectacular of …

The Perception Of Refuse In West African Cities The Case Of Techiman, Ghana, Joseph Mensah

Theses and Dissertations (Comprehensive)

The refuse problem in most West African cities has attained such a massive proportion that even the most insensitive city dweller cannot overlook it. Of the very few studies undertaken on the issue most emphasize the distribution, the magnitude and the economic effects of refuse on the urban environment. Although evidence suggests that culture is the filter through which different environments are held significant by the people, little has been documented on the attitudes and perceptions of West African people in relation to the quality of their environment. The present study analyses the public perception of refuse and how this …

Publications (WR)

A pumped storage system consists of an upper reservoir and lower reservoir separated by an elevation difference. During low demand energy periods such as nights and weekends water is pumped from the lower to the upper reservoir using available energy from conventional steam electric power plants. During high energy demand periods, such as mornings and afternoons of weekdays, upper reservoir water is allowed to drop back down through the same system of water conduits and turbines, generating electricity to conveniently meet abrupt electrical energy requirements. The same water turbines thus act both as pumps and as conventional hydroelectric turbines.

Protecting water quality is essential to preserve the many beneficial uses of western water resources. This conference addresses the dominant federal requirements in the Clean Water Act, including the important major revisions enacted by Congress in 1987, with special attention to western problems regarding nonpoint source pollution. Developments in groundwater quality regulation are considered, as are selected issues concerning the implications of state and federal water quality regulation for the traditional exercise of water rights.
