The paper narrates a systematic literature review on ‘’mangrove ecosystem services’’ to identify their typology, distribution, and utilization within the contemporary scientific literature. We performed a systematic review of 76 research articles derived from the Scopus database, and the dataset was scrutinized and classified against the four major categories of ecosystem services, namely provisioning, regulating, cultural, and supporting services, as per the Millennium Ecosystem Assessment (2005). We attempted to determine the existing state of the interconnectedness of mangrove ecosystem services by mapping the potential synergies and trade-offs. Further, an attempt was made to understand the critical linkages between mangrove ecosystem services and their contribution to the localization/achievement of the Sustainable Development Goals (SDGs). The results suggest disproportionate distribution of scientific literature, where nearly 56 of the studies were concentrated in Asia. The recognition of regulating the services of mangroves, particularly in carbon storage and disaster risk reduction, outnumbered the other types of ecosystem services. In particular, studies related to mangroves’ cultural ecosystem services remain underrepresented. The results show a strong correlation in terms of synergies between the coastal protection ecosystem services and the high carbon sequestration ability of mangroves; and the trade-off between facilitating water transport services and the provision of fresh water. Of the 17 SDGs, three SDGs, namely, SDG 12 (responsible consumption and production), SDG 13 (climate action), and SDG 14 and 15 (life below water and life on land) showed close interrelationships with the existing database. As such, the results are beneficial for coastal planners to better integrate and mainstream mangrove ecosystem services into coastal and regional planning, by maximizing synergies, encouraging the involvement of coastal communities as well as elaborating ameliorative adaptive measures.

Traditional agroforestry systems across South Asia have historically supported millions of smallholding farmers. Since, 2007 agroforestry has received attention in global climate discussions for its carbon sink potential. Agroforestry plays a defining role in offsetting greenhouse gases, providing sustainable livelihoods, localizing Sustainable Development Goals and achieving biodiversity targets. The review explores evidence of agroforestry systems for human well-being along with its climate adaptation and mitigation potential for South Asia. In particular, we explore key enabling and constraining conditions for mainstreaming agroforestry systems to use them to fulfill global climate mitigation targets. Nationally determined contributions submitted by South Asian countries to the United Nations Framework Convention on Climate Change acknowledge agroforestry systems. In 2016, South Asian Association for Regional Cooperation’s Resolution on Agroforestry brought consensus on developing national agroforestry policies by all regional countries and became a strong enabling condition to ensure effectiveness of using agroforestry for climate targets. Lack of uniform methodologies for creation of databases to monitor tree and soil carbon stocks was found to be a key limitation for the purpose. Water scarcity, lack of interactive governance, rights of farmers and ownership issues along with insufficient financial support to rural farmers for agroforestry were other constraining conditions that should be appropriately addressed by the regional countries to develop their preparedness for achieving national climate ambitions. Our review indicates the need to shift from planning to the implementation phase following strong examples shared from India and Nepal, including carbon neutrality scenarios, incentives and sustainable local livelihood to enhance preparedness.
