Risk Reduction Strategies

The Merafong Local Municipality (MLM) has historically suffered financial and human losses because of the presence of dolomite and the consequent formation of sinkholes. There is a great need for the MLM to address the risk posed by sinkholes to ensure the continued safety of communities. However, as the risk is so pervasive, the MLM needs to coordinate their risk reduction strategies with a wide array of stakeholders in the municipality. Efficient stakeholder management is thus crucial if the sinkhole risk is to be addressed appropriately. This article reviews the current status of stakeholder management in the MLM as it pertains to the formulation of a holistic sinkhole risk reduction strategy. Findings indicate that there are serious deficiencies in the MLM’s stakeholder management relating to key risk management processes such as community involvement in risk management structures, disaster risk assessment, training and awareness, and early warning and response. Improved stakeholder management could be characterised by the following factors: improved two-way communication between the municipality and community stakeholders, fostering a relationship based upon trust and equality amongst stakeholders, participation by a wide array of stakeholder groups affected by the sinkhole risk and a mutual commitment by all stakeholders to address the risk. These factors could contribute to enhancing current and future sinkhole risk reduction strategies.

The Impact

The tsunami which devastated Japan in 2011 highlighted the consequences of natural disasters on an area considered to be "best prepared" for such an event. Learning from the direct environmental, social and economic impacts and temporally and spatially displaced indirect global impacts, is important. When seeking to identify and mitigate the impact of proposed developments the process is carried out from two distinct perspectives: "before" and "after" implementation with environmental impact assessment and environmental management the main "instruments" on either side. Drawing on examples from financial institutions and disaster response agencies, this paper explores the theory that coupling the two "instruments" can aid disaster risk reduction and management. It concludes that there is no simple answer and that further research is needed to inform practice.

November 2010 marked the 25th anniversary of the EU Environmental Impact Assessment Directive and the 20th anniversary of its implementation in Germany via the Environmental Impact Assessment Act (EIAA) in 1990. Reflecting back to the original role model for these pieces of legisiation, the 1969 US National Environmental Policy Act (NEPA) can bring some interesting differences to light. Four decades of experience from the more mature US EIA system may hold some important lessons for Germany's younger EIAA. While an outright comparison is impossible at this present time, this article aims to contribute a comparative perspective to show the current status of the original US model, NEPA, and the differences in development and practice to Germany's younger EIAA.

Pakistan, like many other developing countries has adopted the integration of environmental concerns in its social and economic planning. Pakistan has developed some environmental legislation and policies at the national level for the protection and conservation of environment. This paper evaluates the current status of the environmental assessment system in Pakistan and especially in the Khyber Pakhtunkhwa (KP) province by using the Christopher Wood Evaluation Model. The EIA system in Pakistan has many strong features like the legal basis for assessment process, strong apprehension and willingness for screening and scoping, stakeholder’s involvement and participation, mitigation of impacts, and cost & benefits of EIA system. The limitations found in the assessment process of Pakistan includes Preparation of EIA report and its review, monitoring and auditing, strategic environmental assessment, while consideration of alternatives and decision making mechanisms are completely ignored. Besides these, the study revealed the practice of ineffective remedial measures, non-professional, inexperience and unregistered consultants involved in the environmental assessment and sporadically the politically oriented decision making process. This evaluation led to a series of suggestions regarding the improvement of EIA system in Pakistan and especially KP Province with a view to develop its quality and effectiveness.

Vector-borne diseases (VBDs) have re-emerged worldwide due to urbanisation, increase in travel and climate change, becoming a major and serious threat to global public health. In Qatar, the concern has recently risen because of the attribution of the soccer 2022 FIFA World Cup Qatar™, which necessitates fulfilling requirements in terms of prevention and preparedness for disease transmission, including VBDs. This review presents a general overview about current status of vectors and VBDs in Qatar and addresses key challenges and future prospects of control programmes and strategies. It is based on a vector control situation analysis and needs assessment performed during an expert mission in Qatar, November 2017, organised by the WHO Eastern Mediterranean Regional Office and achieved in collaboration with the Ministry of Public Health of Qatar and other local stakeholders. The situation of vectors and VBDs of public health importance in Qatar was analysed based on a systematic literature review by December 31, 2019. The literature reveals that no locally transmitted VBD cases have been recorded in Qatar, but cases were recorded among expatriate workers and travellers who returned from an endemic country. However, data on VBD cases remain scarce except for malaria. The presence of native arthropod vectors is under-recorded to date. A compilation of literature data revealed reports of 30 vector species, including 20 mosquitoes, 2 fleas, 1 louse, 1 fly, and 6 ticks. Overall, Qatar benefits currently from a good surveillance of some VBDs (malaria) and has some capacities in vector control, but no national plan exists, and vector surveillance is in its infancy. In Qatar, clear needs exist in capacity in epidemiology and vector entomology, as well as on the organisational level, and a number of measures are suggested to mitigate and improve VBD risk assessment and management. There is an urgent need to define sustainable solutions for VBD control, management and prevention, and a number of recommendations are suggested.

Water quality characterized as a measure of the physical, synthetic, organic, and microbiological characteristics of water. Water quality monitoring and measurement give an experiential proof to support decision making on issues related to health and environmental impact. Maritime operations are one of the factors that contributed to the environmental impact, particularly on the water quality status. The interactions of Lumut water (Dinding River) with several maritime operations nearby can lead to marine pollution and bring negative effect to the natural habitation. Through preliminary observations, oil spillage and garbage were discovered at the surface water of Dinding River. This study is conducted to identify the current status of water quality at Dinding River. Water samples from 5 fixed stations along the river were collected regularly and analyzed to determine the status of water quality based on the chosen water parameters - Conductivity, Total Suspended Solids, pH, Total Dissolved Solids and Dissolved Oxygen. Pollution Index is used as a tool to determine the status of water quality at the research area. The results show that the water at Dinding River is moderately polluted.

Modified Wood

Wood modification (chemical, thermal, impregnation) represents an assortment of innovative processes continually being adopted in the wood protection sector. COST Action FP1407 “Understanding wood modification through an integrated scientific and environmental impact approach — ModWoodLife” was initiated in 2015, with its 4-year programme aiming to investigate modification processing and products design with emphasis on their environmental impacts. Among the final tasks within COST FP1407 was to re-evaluate the current status of wood modification across the member countries. However, it became clear that activities in other European countries needed to be addressed, and as a result, a more extensive evaluation of wood modification processes across Europe was undertaken, as well as determining the activities globally. This paper outlines some of the recent updates in wood modification, along with summarising data collected by the authors from international colleagues and online sources, so providing an evaluation of the overall global position. These figures suggest that wood modification is undergoing a significant increase in production due to demand, with levels of recent growth seemingly suggesting this will continue for the coming years. Based on data gathered, the global commercial production of modified wood is dominated by thermal modification processes, which produce 1,110,000 m3/year. Among the other commercialised processes, acetylation accounts for 120,000 m3/year and furfurylation 45,000 m3/year. A further global production of around 330,000 m3/year is estimated for other processes, predominantly based on resin-based systems (e.g., Impreg- and Compreg-based processes).
