In response to the global challenge, for a systematic conservation planning approach to MPA establishment, set by the Convention on Biological Diversity and other international agreements and action plans, there are now many initiatives to develop ecologically representative MPA networks. This report describes the progress being made in 30 national and 35 sub-national ecological MPA network initiatives, using information from the literature, MPA practitioners and planners, and conservation experts. The report explores the diverse range of approaches applied, at various spatial and geographical scales, to demonstrate how MPA networks can be established in practice, and how they can be adapted to different needs and priorities.

This report aims to promote a better understanding of the underlying principals and scientific basis behind MPA network design, while disseminating experiences and lessons learned from the initiatives underway at regional national and sub-national levels. The report concludes with a series of six recommendations for the establishment of effective MPA networks, which build on these experiences to capture the complex range of considerations in this rapidly evolving field.

The report is a joint publication between UNEP-WCMC and the UNEP Regional Seas Programme, and was written by Sue Wells, in collaboration with Victoria Sheppard and Hanneke van Lavieren, with support from Nicola Barnard, Francine Kershaw, Colleen Corrigan, Kristian Teleki, Penny Stock and Ellik Adler. The report was launched at the "International Coral Reef Marine Protected Area Network Meeting / 4th ICRI East Asia Regional Workshop" on 17-19th November 2008 in Tokyo, Japan.

The 24 page demonstration atlas, launched at the 14th Conference of the Parties to the United Nations Framework Convention on Climate Change, shows that areas high in both carbon and biodiversity do exist and can be identified by relatively simple mapping tools. Prioritising such areas could give the 'double benefit' of reducing emissions from land use change whilst conserving biodiversity. Three regional maps along with six national maps are shown for the tropics, derived from global-scale data.

Achim Steiner, UN Under-Secretary General and UNEP Executive Director, said: "At a time of scarce financial resources and economic concerns, every dollar, euro or yen needs to deliver double, triple even quadruple dividends. Intelligent investment in forests in developing countries is a key example".

By demonstrating the potential for such 'win win' areas to be identified, the atlas could have particular input to the current discussions on reducing emissions from deforestation in developing countries (REDD).

These new maps are just a first step towards demonstrating how combining different types of data can help to identify areas where opportunities and benefits overlap for storing carbon and protecting biodiversity. A new, detailed and web-based atlas is expected in 2009 in the run up to UN climate meeting in Copenhagen. The atlas will cover a larger number of countries with more accurate, national data on carbon and biodiversity where available, and examine options to include ecosystem services and impacts on local livelihoods. As emphasised by Mr Steiner, ensuring safeguards for local and indigenous people will be paramount to a successful REDD.

The deep sea is the oldest and largest biome on Earth, yet we have little knowledge of the ecosystems and processes in these dark, hidden depths. Only in the last two decades have new technologies enabled scientists to start exploring this last frontier – and their discoveries are fascinating but alarming: the deep sea is teeming with life but is already showing clear signs of anthropogenic impacts despite its remoteness. Many vulnerable deep-sea habitats and communities are being destroyed by fishing and are under threat from increasing exploitation of their mineral and living resources.

Since 2003, the protection, conservation and sustainable use of habitats, ecosystems and biodiversity in the deep sea and high seas have been on the agenda of international meetings. However, our knowledge is insufficient, and the existing governance and management systems are inadequate, to develop, implement and enforce concerted, effective action.

Deep-sea biodiversity and ecosystems responds to key questions, including: where do we find vulnerable deep sea and high sea ecosystems, what are the goods and services they provide, and how are they affected or threatened by existing or emerging human activities and climate change.

Deep-sea biodiversity and ecosystems scopes new ways and perspectives for answering these questions by applying modern methods and concepts used in the context of the Millennium Ecosystem Assessment. With input from leading experts, the report highlights gaps in socio-economic and governance knowledge, analyses shortcomings in assessment methodologies and valuation concepts, and identifies research needs. This results in strong arguments for urgent action to protect and conserve the deep waters, seabed, and high seas, and for the governance and sustainable management of human activities impacting on them. The deep sea is of crucial importance for life on Earth - we have to stop irreversible damages before it is too late.

In 2003, UNEP and the Intergovernmental Oceanographic Commission (IOC) of UNESCO published 'A survey of global and regional marine environmental assessments and related scientific activities' in response to the call of the UN General Assembly (Resolution 57/141) and the Heads of States and Governments at the World Summit on Sustainable Development to establish a regular process for the global reporting and assessment of the state of the marine environment. Today, the urgency to understand the state and functioning of our oceans is even greater than ever. In December 2006, the 61st session of the United nations General Assembly adopted a new resolution (A/RES/61/222) on Oceans and the Law of the Sea, renewing the commitment of Member Stats to support the implementation of the start-up phase: the Assessment of Assessments of the Regular Process.

This sequel builds on the 2003 survey to provide a starting point for the Assessment of Assessments. It lays out the components of an effective assessment and summarizes the key considerations for establishing an assessment process, the findings of this latest survey, an analysis of gaps and emerging issues. It also draws lessons from completed assessment processes.

The report is supported by an interactive online database tool which enables the user to search through assessments and activities relating to the marine envisionment, providing information on the activities and their implementation.

The report and database together are intended to inform and facilitate the task of the Group of Experts undertaking the Assessment of Assessments by providing easy access to essential background information. These tools also provide a valuable new resource for decision makers having to deal with marine environmental issues.

Biodiversity makes possible all forms of economic activity. Damage to components of biodiversity have economic consequences, the impacts of which fall most heavily on the poor. In few contexts is this as clear as in the case of mangrove ecosystems and their dependent human populations. Mangroves support livelihoods in providing habitat for food species, timber for dwellings, cooking and heat, and many other subsistence and commercial activities. Mangroves also provide protection of the coastline from erosion and storm surges. The roles of mangroves are now being realized, but only as the general trend for this valuable habitat is decline.

This report presents a country profile for 19 countries of West and Central Africa, considering the status, distribution, biodiversity, uses, threats and drivers of change for their mangroves. Although there is considerable work being undertaken to research this habitat at the national, regional and global level, there are still significant gaps in information, emphasizing a need for continued efforts to improve assessment in the region. This report concludes that there has been a decline in mangrove cover in the region over the last quarter of a century, and that there will be consequences as a result of this decline.

La biodiversité rend possibles toutes formes d'activité économique. Les dommages subits par les composantes de la biodiversité ont des conséquences économiques dont les impacts sont le plus durement ressentis par les pauvres. Nul autre domaine n'illustre mieux cet état de choses que les écosystèmes de mangroves et les populations humaines qui en sont tributaires. Les mangroves soutiennent les moyens d'existence puisqu'elles servent d'habitat aux espèces alimentaires, sont source de bois pour la construction d'habitations, la cuisine et le chauffage, et sont indispensables à de nombreuses autres activités commerciales et de subsistance. Les mangroves protègent également les zones côtières de l'érosion et des ondes de tempêtes. À l'heure où la tendance générale est au déclin des mangroves, on commence à réaliser pleinement le rôle de cet habitat si précieux.

Le présent rapport fait le bilan de la situation desmangroves de 19 pays d'Afrique occidentale et centrale – statut, répartition géographique, biodiversité, utilisations,menaces et facteurs de changement. Bien que de nombreuses études nationales, régionales et mondiales de cet habitat soient en cours, il reste des lacunes considérables qui soulignent la nécessité de poursuivre les évaluations dans ces régions.

Le rapport conclut qu'il y a eu un déclin des étendues demangroves dans la région au cours des 25 dernières années, et que ce déclin aura des conséquences.
