    Agriculture And Savannah Biodiversity Loss (2005)
    Details
    Publication Date: 2021-05-19
    Description: This paper investigates the question of what influence human beings have had on biodiversity in the region of KwaZulu-Natal in South Africa. A historical analysis has been made of human impact on local ecosystems and species accompanied by statistics on the reduction of habitats and systems caused by urbanisation, cultivation, silviculture and state dams. The major causes of biodiversity loss are identified as being habitat destruction or modification and extractive utilisation. The most important problem is that the government of South Africa does not have an effective environmental management system to ensure wise decision-making. The result has been sectoral ministries empowered with the dual role of both exploiting and preserving natural resources. In 1989 guidelines for Integrated Environmental Management were produced by the Department of Environmental Affairs with an environmental impact assessment procedure. However, the procedure is weak because cumulative and synergistic impacts of development are poorly considered, because the land-use planning framework at the regional and even subregional scale is incomplete, and because there is generally poor understanding of how various land-uses impact on biodiversity. What is more, the procedure hasn't been given force of law due to the worry that the country cannot afford expensive assessment procedures when economic growth is the priority.

    Community structure of corals and reef fishes at multiple scales (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-08-27
    Description: Distributions of numerical abundance and resource use among species are fundamental aspects of community structure. Here we characterize these patterns for tropical reef fishes and corals across a 10,000-kilometer biodiversity gradient. Numerical abundance and resource-use distributions have similar shapes, but they emerge at markedly different scales. These results are consistent with a controversial null hypothesis regarding community structure, according to which abundance distributions arise from the interplay of multiple stochastic environmental and demographic factors. Our findings underscore the importance of robust conservation strategies that are appropriately scaled to the broad suite of environmental processes that help sustain biodiversity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Connolly, Sean R -- Hughes, Terry P -- Bellwood, David R -- Karlson, Ronald H -- New York, N.Y. -- Science. 2005 Aug 26;309(5739):1363-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Coral Reef Biodiversity, Department of Marine Biology, James Cook University, Townsville, QLD 4811, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16123298" target="_blank"〉PubMed〈/a〉

    Social-ecological resilience to coastal disasters (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-08-16
    Description: Social and ecological vulnerability to disasters and outcomes of any particular extreme event are influenced by buildup or erosion of resilience both before and after disasters occur. Resilient social-ecological systems incorporate diverse mechanisms for living with, and learning from, change and unexpected shocks. Disaster management requires multilevel governance systems that can enhance the capacity to cope with uncertainty and surprise by mobilizing diverse sources of resilience.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adger, W Neil -- Hughes, Terry P -- Folke, Carl -- Carpenter, Stephen R -- Rockstrom, Johan -- New York, N.Y. -- Science. 2005 Aug 12;309(5737):1036-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Tyndall Centre for Climate Change Research, School of Environmental Sciences, University of East Anglia, Norwich, NR4 7TJ, UK. n.adger@uea.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16099974" target="_blank"〉PubMed〈/a〉
