Coastal Plains : Land Use And The Environment, P R. George

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

Five years ago, this Journal of Agriculture reported on ways to overcome severe algal pollution of the Peel-Harvey estuarine system, 70 km south of Perth.

Several articles in this Journal of Agriculture discuss improved agricultural practices on the Swan Coastal Plain in particular, although the principals will apply to similar eutrophication of the Slbany harbours, Wilson Inlet and the Vassee-Wonnerup Estuary. They also emphasixe the fine balance between man's demand for potable water and land for rural, industrial and urban use.

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.

Irrigation And Fertilizer Management For Horticultural Crops On The Swan Coastal Plain, I R. Mcpharlin, Greg Luke

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

The Swan Coastal Plain is an important area for the production of vegetables, flowers and fruits in Western Australia. The yellow Cottesloe, Karrakatta and the white-grey Bassendean Sands upon which most of this production is based are infertile in their natural state and require large inputs of fertilizer for succesful production of horticultural crops.

Improved irrigation and fertilizer management will be needed to reduce nutrient leaching from horticultural crops on the coastal plain. This will probably involve applying fertilizer and water more frequently, but in smaller quantaties thaan currently practiced. The result should more closely match water and fertilizer supply …

Planning For Horticultural Expansion On The Swan Coastal Plain, P Coghlan, Geoff Moore, Jim Dixon

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

Horticulture is an intensive, high value form of agriculture highly dependant on the availability of good water supplies for the year-round production of fresh produce. Production increase in Western Australia and the encouragement and development of export markets has caused rapid expansion if the industry in recent years.

Expansion is expected to continue, placing severe pressure on available water supplies and suitable land close to markets. At present' 90 per cent of the Stase's horticultural land is on the Swan Coastal Plain and minor selected hills areas around Perth.

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 …
