Turning the Tide: How Blue Carbon and Payments for Ecosystem Services (PES) Might Help Save Mangrove Forests

In this review paper, we aim to describe the potential for, and the key challenges to, applying PES projects to mangroves. By adopting a “carbocentric approach,” we show that mangrove forests are strong candidates for PES projects. They are particularly well suited to the generation of carbon credits because of their unrivaled potential as carbon sinks, their resistance and resilience to natural hazards, and their extensive provision of Ecosystem Services other than carbon sequestration, primarily nursery areas for fish, water purification and coastal protection, to the benefit of local communities as well as to the global population. The voluntary carbon market provides opportunities for the development of appropriate protocols and good practice case studies for mangroves at a small scale, and these may influence larger compliance schemes in the future. Mangrove habitats are mostly located in developing countries on communally or state-owned land. This means that issues of national and local governance, land ownership and management, and environmental justice are the main challenges that require careful planning at the early stages of mangrove PES projects to ensure successful outcomes and equitable benefit sharing within local communities.

Economic valuation of ecosystem services from coral reefs in the South Pacific: taking stock of recent experience.

The economic valuation of coral reefs ecosystem services is currently seen as a promising approach to demonstrate the benefits of sustainable management of coral ecosystems to policymakers and to provide useful information for improved decisions. Most coral reefs economic studies have been conducted in the United States, Southeast Asia and the Caribbean, and only a few have covered the South Pacific region. In this region, coral reefs are essential assets for small island developing states as well as for developed countries. Accordingly, a series of ecosystem services valuations has been carried out recently in the South Pacific, to try and supply decision-makers with new information. Applying ecosystem services valuation to the specific ecological, social, economic and cultural contexts of the South Pacific is however not straightforward. This paper analyses how extant valuations address the various management challenges of coral reef regions in general and more specifically for the South Pacific. Bearing in mind that economic valuation has to match policy-making contexts, we emphasize a series of specific considerations when conducting and applying ecosystem services valuation in South Pacific ecological and social contexts. Finally, the paper examines the decision-making situations in which extant valuations took place. We conclude that, although ecosystem valuations have been effectively used as a means to raise awareness with respect to coral reef conservation, methodologies will have to be further developed, with multidisciplinary inputs, if they are to provide valuable inputs in local and technical decision-making.

Migration of Senegalese fishers: a case for regional approach to management

This article traces the recent history of Senegalese small-scale fishers’ migration in West Africa. It details how migration of Senegalese fishers developed and then intensified to become a specialized fishing strategy spread out all along the coast of West Africa, from Mauritania to Sierra Leone and beyond. This escalation has rapidly led to the depletion of fish stocks in the region. Today, while fishing migration still largely contributes to food security and provision of sustainable livelihood for coastal communities, this type of migration has reached both an ecological and social deadlock and its future is largely uncertain. Based on current trends in Senegalese fishing migration, this paper highlights the main drivers of changes and impacts of migration. It proposes the development of a regional approach to fisheries management, emphasizing the need for collaborative transnational research projects and stressing the necessity for biodiversity project managers to include the issue of fisheries migration in their regional conservation strategies. It also suggests there may be a need to introduce property rights so as to limit the open access enjoyed by Senegalese migrant fishers almost all over the West African sub-region.
