Global Significance of Mangrove Blue Carbon in Climate Change Mitigation

Background

Mangrove forests sequester proportionately greater amounts of carbon than most terrestrial environments. However, natural greenhouse gas (GHG) fluxes from these ecosystems and the carbon released when they are degraded counteract their carbon sequestration potential. Therefore, it is necessary to examine carbon stocks, rates of carbon sequestration, and carbon losses from these environments to clarify the global and regional potential of mangrove forests to mitigate climate change.

Global potential and limits of mangrove blue carbon for climate change mitigation

Background

Despite national and international policy organizations’ interest in blue carbon financing for mangrove conservation, there is a lack of investment in payments for ecosystem services from the commercial sector. To encourage future investments and scale up blue carbon projects, it is necessary to address knowledge gaps on the financial return on investment for blue carbon projects.

Drivers of global mangrove loss and gain in social-ecological systems

Background

The gain and loss of mangrove forests worldwide depends on both biophysical factors and socioeconomic factors. With global mangrove cover decreasing since the 1990s and biophysical pressures on mangrove forests (i.e., shoreline erosion, extreme weather events) increasing due to climate change, it is important to understand which forms of national conservation policies, programs, governance, and local economic activity most rapidly reverse the rate of loss of mangrove forests.

Les sociétés rurales et les pratiques d’utilisation multiple des terres (Rural societies and land-use practices)

This chapter focuses on rural poverty in central Africa and the contribution of multiple land use practices to local development.

The authors discuss the paradox of belonging to an area that is on the one hand extremely rich in natural resources, and on the other hand extremely poor in national and local development.

They stress the importance of maintaining globally important natural resources that will be able to respond to the needs of future generations of central Africans.

Misreading the African Landscape: Society and Ecology in a Forest-Savanna Mosaic

  • The authors of this book investigate how societies interact with their forested environments through a social anthropological and ecological lense.
  • They challenge widely-accepted views related to the management of Africa's forest margins.

Effet de la lumière des trouées de la canopée sur le potentiel et la dissémination de Gnetum africanum dans les écosystèmes forestiers congolais

This article examines Gnetum africanum, a species of commercial interest in Central African forests. The authors Iinvestigated the importance of light in Gnetum africanum dispersal and regeneration by analysing the effect of canopy gaps on Gnetum africanum in different forest types. Ther determined that Gnetum africanum is a shade tolerant species that needs shade to germinate and prefers low light levels as juveniles.

Investir dans la forêt de demain : vers un Programme d'action pour la revitalisation de la foresterie en afrique de l'Ouest (Investing in the forests of tomorrow)

The authors provide an analysis of Sahelian forests and place the state of forests in West Africa into a historical context. They provide case studies of agroforestry and assisted natural regeneration (ANR) in forested areas of Togo, Burkina Faso, Benin, Niger, Senegal, Gambia, and Guinea. Finally, the authors provide recommendations for smart investments in West African forests.

Occurrence of Nodulation in Unexplored Leguminous Trees Native to the West African Tropical Rainforest and Inoculation Response of Native Species useful in Reforestation

Background

Few studies examine the ability of leguminous tree species to nodulate and fix atmospheric N, especially symbiotically with rhizobia; this study seeks to fill that research gap.  The occurrence of nodulation was determined in 156 mature leguminous species growing in 6 natural forest areas in south-eastern Guinea and an in situ experiment of rhizobia inoculation was performed on 8 selected tree species.
