Natural resources refer to any material or substance that occurs in nature and is valuable to humans, either for its intrinsic qualities or for its use in various industries. These resources can include minerals, water, air, wildlife, forests, and agricultural land. Research in the field of natural resources focuses on understanding the distribution, abundance, extraction, and utilization of these resources, as well as finding sustainable ways to manage and conserve them for future generations. This research area is interdisciplinary, drawing on knowledge and techniques from fields such as geology, biology, economics, and policy analysis. Ultimately, the goal of research in natural resources is to ensure the responsible and efficient utilization of these valuable assets while also protecting the environment and biodiversity.
