Reflections on global environmental change: governance, sustainability and social space

Abstract

The global environmental change shows a great complexity in its data and consequences what poses problems for its  understanding and for evaluating its undergoing risks.
Sustainable development and sustainability are concepts associated to the environmental global change which present limitations on both the semantic point of view and the  operational and appraisal issues. The exploration of the potential links between the scientific spheres and the  sustainability concept points out to complex and mixed relationships. In any way, the understood effects indicate the preeminence of climate as factor and its subsequent incidence on food, health, energy and environment. The analytical  approach to the logics of knowledge reveals the relevance of feeding and health ecology.
Lines or scientific research are proposed on a personal
basis for addressing the following objectives: knowledge progress, risks evaluation, and improvement of energy supplies and uses and environmental conditions.
It is recommended that ethical principles and conducts should be applied in all the global environmental change related  processes: scientific, political, entrepreneurial, social and media information.
