The article includes an analysis of economic growth and alternative growth paths. The article is focused on the concepts of de-linking, re-linking and de-growth. We connected linking analysis (de-linking and re-linking) analytically to the de-growth debate. On the basis of our framework, special cases of de-growth in the linking process relate to strong re-linking, weak re-linking and recessive de-linking. This kind of theoretical approach helps us to define the special nature of de-growth. Key finding of us is that only the de-growth case of recessive de-linking meets the condition of environmental sustainability. However, this case does not fulfil the criteria of sustainable development defined in the WCSD context. In the linking process, the WCSD conditions of sustainable development are met in the strong de-linking process only. In our analytical framework, the theoretical concepts of de-growth and sustainable development seem to conflict by definition.展开更多

At that time, in general, not much attention was paid to the impact of such development on the flooding of vegetation, especially forest stands. Both forested and un-forested terrestrial vegetation types were flooded (244,915 ha creating some 74,075 ha of Islands) in the construction of the Main (Smallwood) Reservoir. The effect of flooding and of the constructions, both above and below the Main Reservoir major dyke system, were the subject of our investigation. This paper, the third in a series, reports on the effect of building the dykes during the early phases of construction with the descriptions of the post flooded conditions below the dykes as related to vegetation. The direct disturbances were excavations, fills, and partial and /or total removal of vegetation cover from fabrication platforms and from gravel and rock extraction sites. No new vegetation cover established in the abandoned quarries and gravel pits. However camp sites and manufacturing platforms were subsequently taken over by Alder growth. The indirect disturbances were the flooding of land areas and the de-watering of sections of the original river and lowering of the water level in some lakes. The results of flooding and the de-watering of some nearby areas are illustrated with aerial photographs and figures showing the environmental impact zones and new shore line development. The flooded trees in large and small pools of stagnant water died suddenly and remain in their original place. New vegetation cover developed on the exposed shore lines of de-watered rivers and lakes.展开更多
