This report analyses the environmental trends for the past twenty years, assesses the present state of the environment and looks into the prospects for shaping a better future for individuals, society, industries, organisations and coming generations. The Mauritius Environment Outlook report has been published at a point in time when the world is preparing for the United Nations Conference on Sustainable Development (RIO + 20) in 2012 to renew their commitment to sustainable development. At the local level, this commitment has been given a new impetus through the “Maurice Ile Durable’ (Mauritius a sustainable island) concept. And to vehicle this concept, the mandate of my Ministry has been broadened to include sustainable development. It is high time we realise that environment is a pre-requisite for development and our well-being. Our natural environment is fundamental in providing resources to produce goods and services, to support the nation, industries and tourism. This report which highlights the policy choices before us will defi nitely contribute in paving the way to make environmental sustainability an integral part of all national development planning. To achieve this, we need to move from words to actions. This will require the appropriate mix of measures including the regulatory and institutional set up, strengthening decision-making and identifying the priorities for action. The report will guide our future endeavours so that we can all work together to make ‘Maurice Ile Durable’ a reality at all levels, from grassroots to the highest political instance. I wish to thank all the organizations and individuals who contributed in the realisation of this report and look forward to their equal full participation and collaborative effort in the implementation phase.
