Document Review

Environmental Impact Assessment (EIA) is a planning tool to identify, predict and evaluate potential environmental impacts and mitigation measures in the early stages of proposed projects. Although EIA has been implemented in Malaysia for over 25 years, the EIA practices have yet to achieve the parameters of effective environmental management and sustainable development. Hence, this research aims to improve the EIA process in Malaysia. Three objectives were utilised in this research which are to recognise the fundamentals of EIA process and procedures applied in Malaysia, to analyse the issues in relation to the EIA preparation and submission conducted in Malaysia and to propose a set of recommendations to further improve the current EIA process in Malaysia. Mixed methods approach was embarked composed of qualitative instruments via document review and semi-structured interviews and quantitative instrument utilising questionnaire survey. Key issues on the EIA process in Malaysia were gathered from qualitative data collected. Analysis of data collected resulted to recommendations on the key issues regarding EIA. 25 proposed recommendations to improve the EIA process were contextualised and validated via questionnaire survey. Ergo, this research established an improved EIA process in Malaysia towards sustainable development to ameliorate the EIA practices in Malaysia.

Common Misconceptions

The Environmental Impact Classification for Alien Taxa (EICAT) can be used to classify alien taxa according to the magnitude and type of their environmental impacts. The EICAT protocol, classifications of alien taxa using the protocol (EICAT classification) and the data underpinning classifications (EICAT data) are increasingly used by scientists and practitioners such as governments, NGOs and civil society for a variety of purposes. However, the properties of the EICAT protocol and the data it generates are not suitable for certain uses. Therefore, we present guidelines designed to clarify and facilitate the appropriate use of EICAT to tackle a broad range of conservation issues related to biological invasions, as well as to guide research and communication more generally. Here we address common misconceptions and give a brief overview of some key issues that all EICAT users need to be aware of to take maximal advantage of this resource. Furthermore, we give examples of the wide variety of ways in which the EICAT protocol, classifications and data can be and have been utilised and outline common errors and pitfalls to avoid.

World population is rapidly growing and expected to reach in between 8.5 to 12 billion by 2100. More than 75% of the population is expected to inhabit in the African and Asian countries having most of the developing nations. The overpopulation leads to a state of food insecurity that induced the evolution of resource-exhaustive agriculture causing irreparable environmental damages. Now the challenge is to feed more with less environmental damages. Adoption of technologically-sound, traditional knowledge inclusive, socio-economically sensible recommended agricultural practices can be the basis for achieving future dietary demands. However, before wider recommendation, their environmental impact assessment at various sustainability issues is necessitated for a holistic understanding of the future agriculture. The challenges of overpopulation and food security can only be managed by identifying the core areas of research and development under different agricultural sectors. The present chapter will provide a brief dimension on some of these key issues.

Executive summary part of an environmental impact assessment report has not received the attention of EIA researchers and professionals even though it is the only part that is often read by most of the stakeholders including decision makers in place of the main report. It is very important that the executive summary is written in a simple non-technical language highlighting key issues and findings from the detailed EIA study while being crisp especially in the developing countries where a large number of development projects are proposed for the economic development and the decision makers are under pressure of time. Executive summaries of 34 EIA reports of different project sectors and prepared by different consultants were evaluated. It is found that these have low robustness, are long, incomplete, and do not justify the term ‘executive’. Guidelines are proposed for comprehensive, effective and objective executive summary to aid decision making.

Silver Extraction

Au-Ag noble metal wastes represent a wide range of waste types and forms with various ballast elements and components. The thiourea process of gold and silver extraction from ores, concentrates or secondary raw materials consists of gold and silver leaching into the thiourea solution and the consequent precipitation of these metals from the solution. Due to the non-toxic character of thiourea it is the perspective alternative to the up to now most frequently used cyanide method. The thiourea leaching of gold and silver from electronic waste, goldsmith’s waste and ceramic waste using crushing as the pretreatment step was investigated. For electronic waste, it was possible to achieve 97 % gold and 94 % silver recovery within 120 minutes of thiourea leaching. Up to 98 % of gold and 96 % of silver were recovered from goldsmith’s waste after 60 minutes of leaching. In the case of ceramic waste, we achieved up to 98 % gold and 97 % silver extraction efficiency after only 45 minutes of leaching. In comparison with the classical cyanide leaching, thiourea leaching acts faster and without a harmful environmental impact.
