“…Both of these habitats have been widely acknowledged as important factors in the protection of coastlines worldwide (Cabral et al 2017). The mangrove trees occupy an area of approximately 350,000ha (Barbosa et al 2001), and their ability to protect population and infrastructures from storms and cyclones has been reported in several studies (e.g. Das and Crépin 2013;Barbier 2016).…”

“…Das and Crépin 2013;Barbier 2016). Moreover, mangroves are themselves an important ecosystem for the subsistence of coastal communities, by providing rich fishing grounds, wood, medicine, coastal erosion protection, thereby contributing to the country's economic development (Barbosa et al 2001). At the same time, the coral reefs on Mozambique's coast range from 413 to 570km 2 (Carissa Wong et al 2005) and are known to dissipate wave energy and assist in the prevention of sea storm effects on habitats and infrastructures of nearby coasts (Van Zanten et al 2014;Costa et al 2016).…”

The incorporation of ecosystem services (ES) information in planning decisions is an important factor in the sustainable use of natural resources. However, studies assessing the levels and changes of these services at national level are rare. In this paper, we estimate past and future changes in multiple ES and biodiversity, as a consequence of land cover change (LCC) in Mozambique. Water yield, water quality, erosion regulation, climate regulation, and biodiversity were modeled using a spatially explicit approach. Changes in ES and biodiversity were mapped at province level between 2005 and 2009. Through the use of a land change model, land cover was projected for 2025, and the resulting impacts on ES and biodiversity were estimated. We found a moderate increase in climate regulating service between 2005 and 2009. However, water quality (nutrient retention) and biodiversity decreased. LCC for 2025 is expected to have a similar impact on these ES. This study contributes with a methodology that can be useful for monitoring ES and assist decision policies affecting ES provision and trade-offs. ARTICLE HISTORY

“…The area of mangrove forest in Mozambique decreased from 408,000 ha in 1972 to 357,000 ha in 2004, resulting in a deforestation rate of 15.9 km 2 ·year −1 [17]. Mangrove deforestation and degradation is mainly attributed to anthropogenic causes such as collection of firewood, charcoal, poles production, salt production, water pollution, and changes in freshwater flow of the main rivers due to dam construction upstream [12,[15][16][17][18]. However, coastal sand deposition has also been indicated as one of the causes of massive mangrove mortality [19,20].…”

Mangroves could be key ecosystems in strategies addressing the mitigation of climate changes through carbon storage. However, little is known regarding the carbon stocks of these ecosystems, particularly below-ground. This study was carried out in the mangrove forests of Sofala Bay, Central Mozambique, with the aim of quantifying carbon stocks of live and dead plant and soil components. The methods followed the procedures developed by the Center for International Forestry Research (CIFOR) for mangrove forests. In this study, we developed a general allometric equation to estimate individual tree biomass and soil carbon content (up to 100 cm depth). We estimated the carbon in the whole mangrove ecosystem of Sofala Bay, including dead trees, wood debris, herbaceous, pneumatophores, litter and soil. The general allometric equation for live trees derived was [Above-ground tree dry weight (kg) = 3.254 × exp(0.065 × DBH)], root mean square error (RMSE = 4.244), and coefficient of determination (R 2 = 0.89). The average total carbon storage of Sofala Bay mangrove was 218.5 Mg·ha , of which around 73% are stored in the soil. Mangrove conservation has the potential for REDD+ programs, especially in regions like Mozambique, which contains extensive mangrove areas with high deforestation and degradation rates.

“…The Zambezi River Delta contains one of the largest mangrove forests in eastern Africa, comprising a large portion of the country's total mangrove area, which is greater than 2% of global mangrove extent [1,2]. These mangrove forests are recognized for supporting terrestrial and marine biodiversity [3], containing large carbon stocks [4] and providing essential ecosystem services to local communities, which equate to significant economic value [5].…”

The Mangroves of the Zambezi Delta: Increase in Extent Observed via Satellite from 1994 to 2013

Abstract:Mangroves are recognized for their valued ecosystem services provision while having the highest carbon density among forested ecosystems. Yet they are increasingly threatened by deforestation, conversion to agriculture and development, reducing the benefits they provide for local livelihoods, coastal protection and climate change mitigation. Accordingly, accurate estimates of mangrove area and change are fundamental for developing strategies for sustainable use, conservation and Reducing Emissions from Deforestation and Degradation (REDD+). The Zambezi River Delta in Mozambique contains one of the largest mangrove forests in Africa, and deforestation has been reported to be substantial, however these estimates vary widely. We used Landsat imagery from 1994, 2000 and 2013, to estimate a total current mangrove area of 37,034 ha, which is a net increase of 3723 ha over 19 years. The land cover change assessment was also used to provide perspective on ecosystem carbon stocks, showing that the Zambezi Delta mangrove ecosystem acts as a large carbon sink. Our findings reinforce the importance of conducting land cover change assessments using coherent data and analytical models, coupled with field validation. Broader application of our approach could help quantify the rates of natural change from erosion and land aggradation contrasted with anthropogenic causes.
