Public perceptions of mangroves
Social media has emerged as a prominent factor in shaping public perceptions. However, significant gaps remain in our understanding of the complex interplay between social media and human-nature relationships, including for mangrove ecosystems. We assessed how mangroves have been discussed and perceived on social media by analysing 649,495 Twitter/X posts between 2010 and 2022. Using NRC and AFINN lexicons, we found a prominence of positive senti…
Recommendations for strengthening blue carbon science
Blue carbon (BC) habitats (e.g., mangroves, tidal marshes, and seagrasses) are important CO2 sinks but are among the most threatened ecosystems on Earth. Substantial research over the last decade has quantified BC to evaluate the climate benefits associated with habitat conservation and restoration. However, the exponential growth in BC science has resulted in differing approaches that hinder comparison across studies and increase uncertainty. He…
Implementation costs of restoring global mangrove forests
Mangroves provide numerous ecosystem services and are increasingly recognized as a natural climate solution. As a result, multiple recent initiatives have set ambitious mangrove restoration targets. However, there has been little research estimating the costs of achieving such targets, either site by site or in aggregate. Here, we spatially model the costs of restoring mangroves globally based on reported implementation costs from 249 restoration…
Bridging conservation and policy
The Kunming–Montreal Global Biodiversity Framework (GBF) aims to halt biodiversity loss by 2030, with Targets 1 and 3 focusing on reducing forest loss and expanding protected areas. Mangroves, as biodiversity hotspots offering crucial ecosystem services, have seen some conservation gains, yet key drivers of high-value mangrove loss remain unaddressed in intergovernmental policy frameworks. It is the first global assessment linking GBF Targets 1 &…
Perceptions of coastal vegetated ecosystems
Coastal vegetated ecosystems such as mangrove forests, seagrass meadows, and tidal marshes provide a wide array of ecosystem services. They also play a vital role in climate change mitigation through carbon sequestration. However, they are among the most threatened ecosystems globally. This study addresses a key knowledge gap by conducting a systematic review of academic literature on sectoral perceptions of these ecosystems. Through content anal…
Rapid mangrove sediment accretion in late-Holocene paleochannels of Singapore
The evolution of mangroves in response to sea-level rise will partially depend on the availability of accommodation space, which is influenced by the hydrodynamic setting. Here, we reconstruct mangrove evolution in a paleochannel of Sungei Jurong (i.e., Jurong River), Singapore via litho-, bio-, and chrono-stratigraphical analyses. Paleochannels are a commonly-occurring, but under-studied hydrodynamic setting in mangroves. Our results show a stra…
Mangrove-based carbon market projects
Restoring mangroves lost by aquaculture offers large blue carbon benefits
The Mangrove Restoration Tracker Tool
Restoration is a key component of global and national efforts to combat ecosystem degradation, reduce biodiversity loss, and adapt to climate change, and there is currently an impetus to scale up restoration efforts. However, our ability to track progress toward restoration targets is limited by the lack of consistent and standardized data on objectives, interventions, and outcomes. To address this, a collaboration of conservation practitioners a…
The next phase of Wires Climate Change
Geographic distribution of articles published in WIREs Climate Change in the last 5 years, with bubbles scaled by the number of articles per country. Climate change is one of the grand socio-environmental challenges of our time, influencing almost all aspects of life on Earth. The multifaceted and all-encompassing nature of the problem means we need to understand climate change in multi-, inter- and transdisciplinary ways. When WIREs Climate Chan…
Blue carbon science, management and policy across a tropical urban landscape
The ability of vegetated coastal ecosystems to sequester high rates of “blue” carbon over millennial time scales has attracted the interest of national and international policy makers as a tool for climate change mitigation. Whereas focus on blue carbon conservation has been mostly on threatened rural seascapes, there is scope to consider blue carbon dynamics along highly fragmented and developed urban coastlines. The tropical city state of Singa…
The potential for mangrove and seagrass blue carbon in Small Island States
Blue carbon is attracting substantial interest as a natural climate solution. Focus has been on countries with large blue carbon stocks, though the high carbon densities of blue carbon ecosystems make them suitable for Small Island States with small coastal habitats. Small Island States hold 1806–2892 Tg of blue carbon, and mangroves alone offset >10% of land use emissions for 11 Small Island States, highlighting their potential contribution to n…
Maximising resilience to sea-level rise in urban coastal ecosystems through systematic conservation planning
Coastal cities and their natural environments are vulnerable to the impacts of climate change, especially sea-level rise (SLR). Hard coastal defences play a key role in protecting at-risk urban coastal populations from flooding and erosion, but coastal ecosystems also play important roles in the overall sustainability and resilience of cities and urban centres by contributing to coastal protection. Conserving coastal ecosystems and maximising the…
Operationalizing marketable blue carbon
Methane and nitrous oxide emissions complicate the climate benefits of teal and blue carbon wetlands
Blue (coastal wetlands) and teal (inland wetlands) carbon ecosystems are long-term carbon sinks and are regarded as essential natural climate solutions. Yet, the same biogeochemical conditions favoring high carbon storage also promote the production of two potent greenhouse gases (GHGs)—methane and nitrous oxide—which can reduce the climate change mitigation potential of wetlands. Complex processes regulate the production and consumption of the t…
Achieving ambitious mangrove restoration targets will need a transdisciplinary and evidence-informed approach
Mangrove forests under climate change in a 2°C world
The world's nations are committed to keeping global temperature rises to less than 2°C to avoid the worst impacts of climate change. Such a target is crucial for mangrove forests, because they are located primarily in tropical and subtropical regions that are expected to see large changes in climatic conditions; their intertidal location and sensitivity to changes in environmental conditions means that mangroves are expected to be on the front li…
Integrating blue
Blue Carbon Ecosystems (BCEs) help mitigate and adapt to climate change but their integration into policy, such as Nationally Determined Contributions (NDCs), remains underdeveloped. Most BCE conservation requires community engagement, hence community-scale projects must be nested within the implementation of NDCs without compromising livelihoods or social justice. Thirty-three experts, drawn from academia, project development and policy, each de…

Scientific evidence for ecosystem-based disaster risk reduction
Harnessing Big Data to Support the Conservation and Rehabilitation of Mangrove Forests Globally
Mangrove forests are found on sheltered coastlines in tropical, subtropical, and some warm temperate regions. These forests support unique biodiversity and provide a range of benefits to coastal communities, but as a result of large-scale conversion for aquaculture, agriculture, and urbanization, mangroves are considered increasingly threatened ecosystems. Scientific advances have led to accurate and comprehensive global datasets on mangrove exte…

Drivers of mangrove ecosystem service change in the Sundarbans of Bangladesh
Mangroves are now well known to provide a range of ecosystem services that benefit local populations, though such ecosystem services are at risk from mangrove deforestation and degradation across much of the tropics. This study aimed to identify the natural and anthropogenic drivers of change that affect ecosystem services of the Sundarbans mangrove forest. Secondary data analysis and primary fieldwork were conducted in three districts in the Sun…
Mangrove forest dynamics in Tanintharyi, Myanmar from 1989–2014, and the role of future economic and political developments
Mangrove forests in Southeast Asia provide many ecosystem services, though are experiencing extensive deforestation, especially in Myanmar. Recent political and economic reforms in Myanmar are projected to further increase development pressures on natural resources. Mangrove forests in the southern state of Tanintharyi have largely been spared clearance because of poor infrastructure and a volatile security situation, though this may change with …
"Unlearning "Landscape
Landscape is a key concept in geography, one that has been critically engaged with by geography's subdisciplines using various conceptual and methodological approaches. Thus, landscape should be a key foundation with which to engage intradisciplinarity within geography. From a variety of strands within geography, however, the definitions that have emerged around landscape can still exclude a range of other voices and perspectives that can usefull…

Geography's role in nurturing postgraduate students
In this commentary we encourage thinking about how to effectively nurture postgraduate students in geography. We offer some ideas and strategies for supervisors who mentor postgrads for careers in and beyond the academy. We also consider how supervisor-student relationships can take advantage of geography's interdisciplinarity to develop a well rounded postgraduate experience
Incorporating “virtual” and “real world” field trips into introductory geography modules
The “field trip” is a key pedagogical tool within geographical education to encourage deep learning, though they are increasingly difficult to implement due to reduced budgets, safety concerns and increasing class sizes. We incorporated three field-learning activities into a large introductory module. A traditional staff-led trip was the most effective activity in terms of enjoyment, knowledge, and deep thinking and awareness. Self-paced field ac…

Rates and drivers of mangrove deforestation in Southeast Asia, 2000–2012
Significance This study quantifies the proximate drivers (i.e., replacement land uses) of mangrove deforestation across Southeast Asia between 2000 and 2012. Mangrove forests in the region were lost at an average rate of 0.18% per year. Aquaculture was a major pressure on mangrove systems during this period, but its dominance was lower than expected, contrary to popular development narratives. Rice agriculture has been a major driver of mangrove …
