In Malaysia, environmental impact assessment (EIA) has been mandatory since 1988 as a proactive tool in environmental management for 19 prescribed activities. Since ecological information is an important component in EIA, this study examined the quality of ecological input in 41 preliminary EIAs for coastal resort development. Twelve criteria relating to ecological data, impact prediction, evaluation of impact significance, mitigating measures, residual impacts, monitoring, communication of the report and consultants were reviewed. Results revealed that only 27 percent of the EIAs were found to be satisfactory, whereas the others were at borderline or poor. In describing the existing environment, the majority of the reports made no mention of the survey methods, some of the data included were found to be not site-specific and up-to-date, and the sources of the secondary data presented in these reports were mostly not quoted. There was a tendency to survey terrestrial habitats more than aquatic, and higher plants are surveyed more than animals. Most of the reports also failed to mention the species status although comprehensive lists of species were present. They also failed to quantify the species present in the impacted areas which could lead to inadequate ecological impact prediction. The study also showed that, though all the reports contained a section on ecology, not all the EIA consultants involved in preparing these reports comprised of a multidisciplinary team that has an ecologist/biologist or environmental scientist.

Rock fragmentation in mining and construction industries is widely achieved using drilling and blasting technique. The technique remains the most effective and efficient means of breaking down rock mass into smaller pieces. However, apart from its intended purpose of rock breakage, throw, and heave, blasting operations generate adverse impacts, such as ground vibration, airblast, flyrock, fumes, and noise, that have significant operational and environmental implications on mining activities. Consequently, blast impact studies are conducted to determine an optimum blast design that can maximize the desirable impacts and minimize the undesirable ones. To achieve this objective, several blast impact estimation empirical models have been developed. However, despite being the industry benchmark, empirical model results are based on a limited number of factors affecting the outcomes of a blast. As a result, modern-day researchers are employing machine learning (ML) techniques for blast impact prediction. The ML approach can incorporate several factors affecting the outcomes of a blast, and therefore, it is preferred over empirical and other statistical methods. This paper reviews the various blast impacts and their prediction models with a focus on empirical and machine learning methods. The details of the prediction methods for various blast impacts—including their applications, advantages, and limitations—are discussed. The literature reveals that the machine learning methods are better predictors compared to the empirical models. However, we observed that presently these ML models are mainly applied in academic research.
