The challenges of obtaining information on extraction activities

The challenges of obtaining information on extraction activities

The DPSIR (Drivers – Pressures – States – Impacts – Responses) approach permits to describe the relationship between the human activities and the environment. Overall, this approach provides a mechanism for analysing environmental problems with regards to sustainable development. It has been a key issue for the development of legislation focused on the protection of the environment such as the European Marine Strategy Framework Directive. Therefore, it is of capital importance to obtain good quality … Read entire article »
