A team of environmentalists is proposing the establishment of a protected area that integrates conservation efforts with sustainable development. This proposed area aims to safeguard biodiversity while allowing human activities that are compatible with nature conservation. Which type of protected area aligns best with the team's objectives?
Q.2
A small town located in a desert region is experiencing frequent power outages due to an ageing grid infrastructure. The town council is considering investing in renewable energy to improve energy security and reduce reliance on the grid.
