This process helps ensure that decision-makers consider environmental consequences and public input, promoting sustainable development and protecting natural resources.
Executive Summary: An executive summary is a concise overview of a larger document or report, designed to give readers a quick understanding of the main points without having to read the entire text. It typically includes the purpose, findings, conclusions, and recommendations, allowing decision-makers to grasp essential information efficiently. This summary is particularly important in contexts like environmental impact assessments, where stakeholders need to quickly understand potential impacts and proposed measures.
Geographic Information Systems (GIS): Geographic Information Systems (GIS) are computer-based systems that allow for the capture, storage, analysis, and visualization of spatial and geographic data. These systems enable users to understand relationships, patterns, and trends in data related to geographical locations, making them crucial for planning and decision-making processes across various fields.
Habitat fragmentation: Habitat fragmentation refers to the process where large, continuous habitats are divided into smaller, isolated patches due to various human activities, such as urban development, agriculture, and infrastructure projects. This division can disrupt the ecosystems within these habitats, impacting biodiversity and species interactions, while also influencing the management and restoration of coastal environments.
Impact Prediction: Impact prediction refers to the process of assessing the potential consequences of a proposed project or action on the environment, society, and economy.
