Book Description
Building on work presented at the IUCN World Parks Congress (WPC) held in Australia in 2014, this document outlines experiences with aquatic protected areas (PAs), marine protected areas (MPAs) and protected areas in inland waters in the context of livelihoods and food security. It provides a general overview of MPAs and reports on their interface with livelihoods and food security, based on case studies in Africa, Asia, Latin America and Oceania. It also synthesizes the papers conclusions and discusses the observed outcomes of aquatic PAs, together with problems and solutions.

Book Description
This book presents the natural, environmental and scenic richness of the world’s coastal and marine areas classified by UNESCO as “Natural World Heritage Sites”. Representing well-preserved areas of exceptional significance to the planet and to humankind, they include a total of 49 marine sites, formed by reefs, atolls and gulfs, and 35 coastal sites in all oceans and all continents with exception of Antarctica. They are being protected and preserved from most degrading uses for future generations as an important legacy from the past. Exploring their richness, this book analyzes and explains these sites in a clear, understandable, scientific way, and is of interest to all who work in or care about the geosciences, environmental sciences and biosciences.

Book Description
This volume on the ecology of Mauritanian coastal waters and in particular the Banc d'Arguin, allows us to understand the functioning of this remarkable coastal wetland. Major questions concern the interaction between the Banc d'Arguin ecosystem on the one hand and the adjoining systems of the open ocean with its intensive upwelling phenomena and the Sahara desert on the other. Is the Banc d'Arguin ecosystem relatively isolated from its surroundings and does it function as a tropical pocket in a more temperate surrounding, as suggested by Sevrin-Reyssac (1983); or does it interact with both the Sahara and the Atlantic Ocean? At the Banc d'Arguin, the area between the estuarine parts and the open ocean is extremely shallow and largely uncharted. Large research vessels cannot penetrate the shallows, whereas small vessels are often unable to negotiate the outer part of the shallow area due to rough weather conditions. Hence, separate teams report on work at the seaward side of this shallow sill and at the landward side. In addition, other teams address different questions, such as the productivity of the seagrass beds and the benthic fauna, the number of birds spending the summer at the Banc d'Arguin, and the distribution of several taxonomic groups of flora and fauna.

Book Description
Ecosystem valuation is a process that assigns a monetary value to the benefits that are provided by an ecosystem and its ecosystem services. This study carries out the economic valuation of marine and estuarine coastal ecosystem services in the Canary Current Marine Ecosystem (CCLME). The CCLME stretches along the coast of Western Africa, from Morocco to Guinea, and is characterized by high biological productivity due to the upwelling of deep, cold oceanic waters along this coast. This also supports a high abundance of fish resources (both pelagic and demersal) and overall high biodiversity. This study reviews and assesses ecosystem services provided by the marine areas, coastal mangroves and seagrass meadows. These coastal areas not only provide habitats for some commercial fish species, but also feeding grounds, nurseries, or refuges. Therefore, mangroves and seagrasses can play an important role in maintaining fish stocks. L’évaluation des écosystèmes est un processus qui attribue une valeur monétaire aux avantages offerts par un écosystème et ses services écosystémiques. Cette étude cherche à réaliser une évaluation économique des services des écosystèmes côtiers marins et estuariens dans l’écosystème marin du courant des Canaries (CCLME). Le CCLME s’étend le long des côtes de l’Afrique de l’Ouest, du Maroc à la Guinée, et se caractérise par une productivité biologique élevée due à la remontée d’eaux océaniques froides et profondes (upwelling) le long de cette côte. Cela favorise également une grande abondance de ressources halieutiques (pélagiques et démersales) et une biodiversité globale élevée. Cette étude examine et évalue les services écosystémiques fournis par les zones marines, les mangroves côtières et les herbiers marins. Ces zones côtières fournissent non seulement des habitats pour certaines espèces de poissons commerciales, mais constituent également des aires d’alimentation, de nourriceries ou des refuges. Par conséquent, les mangroves et les herbiers marins peuvent jouer un rôle important dans le maintien des stocks de poissons.

Book Description
Coastal zones are places where environments, cultures, and economies all collide and interact, and Challenging Coasts examines the important issues involved in managing coastal zones. Contributors to the volume argue that coastal zones pose a developmental rather than a management challenge and require a multidisciplinary response from the social and natural sciences. Thus papers collected here examine international case studies and address a variety of issues such as biodiversity protection and the legal concerns of habitat protection. Challenging Coasts is an important and invaluable resource for marine scientists and those interested in coastal zone development.
