Protracted Environmental Issues on a Proposed Titanium Minerals Development in Kenya's South Coast     

J. O. Z. Abuodha  P. O. Hayombe 《Marine Georesources & Geotechnology》2006,24(2):63-75

This study takes cognizance of the fact that the TIOMIN (TIOMIN Resources Inc. of Canada) project has resulted in controversy over its handling of environmental issues and especially the Environmental Impact Assessment (EIA). The authors address many of the protracted issues that have slowed the development of the mining project in Kwale. The main emphasis is on the impacts of the mining and mineral separation processes on the environment, including the governing legislation, the role of consultation and public participation, and socioeconomic issues. In their public documents TIOMIN has specified neither the type of minerals it wants to extract from the area nor their chemical composition. It is well known, however that the titanium minerals and zircon targeted have impurities of iron, thorium and uranium. In the absence of an Environmental Management Plan, the effects of stockpiling radioactive wastes and other impurities that could possibly lead to environmental degradation in both the terrestrial and marine environments have not been publically addressed. The measures proposed to mitigate ecological damage as a result of the establishment of a minerals processing plant in the area seem inadequate. Pollution resulting from accidental spillage or breakage could have significant impact on marine life and residents living near the mining site. Other issues that have not been addressed satisfactorily pertain to the use of surface and underground water. The area already faces a huge water deficit and the calculations presented on aquifer recharge and stream flow rates do not indicate the large quantities of water that would be required in the mineral processing plant. The project, if approved in its present state, risks violation of international conventions. Furthermore, it could cause a conflict between Kenya and Tanzania in the event of an oil spill at the proposed ship loading facility at Shimoni. The proposed mining area includes the district's most fertile land, is home to many fisherfolk and is a major tourist destination. An analysis of the effects of this project on other available opportunities must be thoroughly understood to ascertain the economic and environmental benefits and costs of the mining venture. The proposed compensation rate of $1,000 per acre, for resettlement for example, appears to be grossly inadequate. Compensation should take into account family size and structure family assets and the cost of relocation.  相似文献

重庆市镇安场变形体与库岸岸勘查治理     

付治国  印修章  田修启 《中国地质灾害与防治学报》2006,17(1):28-32

对镇安场变形体、库岸特征及其稳定性研究目的是为三峡水库区三期地质灾害勘察与治理提供参考依据。通过对该变形体的工程地质勘察,取得了变形体及滑移带的近期变形特征,确定出变形体的稳定系数。给出变形体在天然状态下、连续高强度暴雨、水库蓄水位达175m及降至145m时荷载受力情况下的一系列参数,并作出稳定性简评。通过对库岸现状的定量勘查,采用对未来坍岸破坏方式的预测,用类比及计算法得出当库水位动、静态发生改变时变形体的变形情况及变形体与库岸防治设计的有关参数。其中浅基础下岩石地基承载力的经验参数为:强风化泥岩300kPa,强风化砂岩500kPa,中等风化泥岩1000kPa,中等风化砂岩2000kPa;基底摩擦系数为:泥岩0.4,砂岩0.5;墙后填土重度20kN/m3。按上述各项参数实施防治措施将取得较好的效果。  相似文献   

北京市地面沉降发展及对城市建设的影响   总被引：3，自引：1，他引：3

地面沉降是北京市平原区主要地质灾害之一,最早在1935年发现于西单至东单一带,到目前为止已经形成了多个地面沉降中心,到2005年底,累计沉降量大于50mm的沉降区达4114 km~2,大于100mm的沉降区达2815km~2。地面沉降已经对城市基础设施造成一定程度的破坏,并且已经对奥运场馆、规划新城、CBD等重要区域构成潜在威胁,所以必须及时制定完善的防治措施来降低地面沉降的危害。  相似文献   

Assessment of Man-made and Natural Hazards in the Surroundings of Hydropower Projects under Construction in the Beas Valley of Northwestern Himalaya     

Sanjeev Sharma Jagdish C. Kuniyal J. C. Sharma 《山地科学学报》2007,4(3):221-236

Mountain ecosystem,on the earth,has plenty of natural resources. In Himachal Pradesh all the rivers are snowfed and therefore rich in water resources. These resources have been supporting enough for the generation of electricity through introducing hydropower projects since the last decade. However,every developmental activity has its own negative impacts on the surrounding environment. Due to the fragile nature of topography and delicacy of ecology of the Himalaya,it results in lot of disturbances because of high degree of human interferences like construction of major hydropower projects. The increased extent of geological hazards,such as landslides,rock fall and soil erosion,have mainly due to alike developmental interventions in the natural ecosystem. So understanding and analysing such impacts of the hydropower projects have mainly been on the environment in various forms but natural hazards have been frequent ones. The present study,therefore,focuses mainly on the Parbati Stage Ⅱ (800 MW) and the Parbati Stage Ⅲ (520 MW) hydropower projects; both of which fall within the Kullu district of Himachal Pradesh. Based on the perception survey of the local communities,the existing land use pattern,status of total acquired land of the residents by hydropower projects,frequent natural hazards and resultant loss to the local communities due to upcoming construction of hydropower projects surrounding to the Parbati Stage Ⅱ and Ⅲ have been analysed in the paper. Also,the preventive measures to mitigate these adverse impacts have been suggested to strengthen these projects in eco-friendly manner in the mountain context.  相似文献

‘Ageing out of place’: Experiences of resettlement and belonging among older Bhutanese refugees in New Zealand          下载免费PDF全文

Natalie Slade  Maria Borovnik 《New Zealand geographer》2018,74(2):101-108

Previous research has suggested that older refugees are particularly vulnerable to the stresses of resettlement in developed countries. However, to date the voices of older refugees have largely been missing from the body of refugee resettlement research. Using in‐depth interviews and thematic analysis, this paper explores the personal resettlement experiences of three former refugee elders from the Bhutanese community in Palmerston North. The findings suggest that culture, religion and social connections are of vital importance to the well‐being of these Bhutanese elders and their ability to foster a sense of self and place in a foreign land.  相似文献
