Widespread urban expansion around the world, combined with rapid demographic and climatic changes, has resulted in serious pollution issues in many coastal water bodies. To help formulate coastal management strategies to mitigate the impacts of these extreme changes (e.g., local land-use or climate change adaptation policies), research methodologies that incorporate participatory approaches alongside with computer simulation modeling tools have potential to be particularly effective. One such research methodology, called the “Participatory Coastal Land-Use Management” (PCLM) approach, consists of three major steps: (a) participatory approach to find key drivers responsible for the water quality deterioration, (b) scenario analysis using different computer simulation modeling tools for impact assessment, and (c) using these scientific evidences for developing adaptation and mitigation measures. In this study, we have applied PCLM approach in the Kendrapara district of India (focusing on the Brahmani River basin), a rapidly urbanizing area on the country’s east coast to evaluate current status and predict its future conditions. The participatory approach involved key informant interviews to determine key drivers of water quality degradation, which served as an input for scenario analysis and hydrological simulation in the next step. Future river water quality (BOD and Total coliform (Tot. coli) as important parameters) was simulated using the Water Evaluation and Planning (WEAP) tool, considering a different plausible future scenario (to 2050) incorporating diverse drivers and pressures (i.e., population growth, land-use change, and climate change). Water samples (collected in 2018) indicated that the Brahmani River in this district was already moderately-to-extremely polluted in comparison to the desirable water quality (Class B), and modeling results indicated that the river water quality is likely to further deteriorate by 2050 under all of the considered scenarios. Demographic changes emerged as the major driver affecting the future water quality deterioration (68% and 69% for BOD and Tot. coli respectively), whereas climate change had the lowest impact on river water quality (12% and 13% for BOD and Tot. coli respectively), although the impact was not negligible. Scientific evidence to understand the impacts of future changes can help in developing diverse plausible coastal zone management approaches for ensuring sustainable management of water resources in the region. The PCLM approach, by having active stakeholder involvement, can help in co-generation of the coastal management options followed by open access free software, and models can play a relevant cost-effective approach to enhance science-policy interface for conservation of natural resources.

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.

Reversing ecosystem degradation and halting global biodiversity loss due to climate change and other anthropogenic drivers are essential for socioeconomic development and human wellbeing, as well as for advancing global sustainability. The latest initiative in this direction is the 'Post-2020 Global Biodiversity Framework', which establishes a blueprint for global coordinated action towards development of national and regional strategies targeting conservation and sustainable utilization of biodiversity. By supporting the notion of 'ecological civilization', it emphasises the need for transformative strategies to conserve, monitor and sustainably manage ecosystems by 2030. Arguably the articulation of fit-for-purpose goals and targets is a key precondition for achieving this vision by enhancing cooperation and influencing the development of implementation strategies and regulatory instruments at national and local levels. The present Policy Analysis critically reviews the key features of the draft Post-2020 Global Biodiversity Framework and suggests recommendations to further strengthen it.

This article provides evidence and a rationale based on adaptive governance studies for why creating meaningful youth engagement should be understood in terms of intergenerational dialogue, collaboration, learning, and substantive decision-making in global environmental governance. We have centered our discussion on the International Union for the Conservation of Nature (IUCN), as the largest global conservation organization. Through an organizational ethnography approach, we have demonstrated how generational concerns within the IUCN have been framed in terms of participation, and then present the IUCN Intergenerational Partnership for Sustainability (IPS) as a case study of a grassroots movement that is focused on transforming the IUCN towards being a fully intergenerational global governance system for nature conservation. We have described the development of intergenerational thinking and action within the IUCN, and discussed intergenerational governance as being essential for addressing nature conservation challenges faced by local communities in times of increasing global uncertainty. We conclude by providing recommendations for enhancing intergenerational dialogue and building intergenerational governance structures within global conservation organizations.

Land degradation due to mining is a major concern leading to massive losses of biodiversity and ecosystem services. The biomonitoring of metals in mine voids can help to keep track of ecosystem health. The present study was carried out in a large mine void that is presently used for fly ash disposal in the Angul district of Odisha, India. For the biomonitoring of the fly ash, composite soil and plant samples (non-edible as well as edible, naturally growing in and around the mine void) were collected seasonally four times between April 2018 and February 2019 from the sampling locations. We monitored the metal uptake (Al, Cd, Cr, Fe, Mn, Ni, Pb, Zn) and bioaccumulation to assess the bioaccumulation factor (BAF) in the collected plant samples. The Fe concentration was reported to be high in Tragia involucrate (24.82 mg/kg) and Digitaria ciliaris (24.818 mg/kg), while the soil at the study site is also rich in Fe and Al. Higher concentrations of metals in fruit trees such as Psidium guajava and other plants such as Ficus religiosa, Ipomoea batatas, Delonix regia, Digitaria ciliaris, and Cynodon dactylon were reported from nearby areas. Understanding the presence of metals should be a guiding factor for reducing land degradation. Our study stresses the need for corporate commitment to ensure regular biomonitoring and biomonitoring-supported land restoration for degraded mining areas. Sustainable land restoration supported by biomonitoring has the potential to help achieve the global goals of the UN Decade on Restoration: Land Degradation Neutrality (UNCCD) and Sustainable Development Goals (SDGs) 12, 13, and 15.

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.

Forests of Jammu and Kashmir (J&K) have a rich diversity of valuable non-timber forest products (NTFP) that local communities extract for their sustenance and income. The region is home to over 60% of species recognized for novel bio-medicinal properties in the Indian Himalayas. There is significant national and international demand for these species, providing income and employment for more than 60% of the population of J&K. Despite this, NTFP are not adequately recognized for their contributions to rural livelihoods and the regional economy due to the lack of appropriate policy and governance mechanisms. In this study, we embrace a bioresource vision to examine challenges and opportunities for transition to a sustainable bioeconomy in J&K. Selected NTFP were considered for valuation to showcase their bioeconomy potential using two approaches. First, we used the ‘market price method’ to estimate the contribution of NTFP to the local economy. Second, the ‘maximum willingness to pay method’ was used to project the bioeconomy potential of NTFP in the region. The analysis reveals that local communities’ revenues could increase by as much as 18 times their current price with appropriate actions to include NTFP. However, to realize this potential, policies and governance frameworks based on increased access and benefit sharing with inclusive institutional models would support the transition of the local economy into a bioeconomy. Fostering public–community partnership by improving the local participation of producers and processors in NTFP value chains for overcoming the existing governance barriers is needed.

Forests have been very important natural resource for rural subsistence lifestyle providing variety of and provisioning ecosystem services. Study was carried out in six villages of upper Kedarnath valley at an altitudinal gradient of 1400–2800. Paper examines the nature and extent of provisioning services from forests to hill locals living in nearby villages. Frequent field survey of 151 households from five villages in proximity to forest was conducted using semi-structured questionnaires followed by field surveys. Primary data were collected for basic household’s attributes, fuelwood, fodder, leaf litter and NTFP collection pattern. Simple descriptive methods were used for data analysis. The result shows that fuelwood contributes more than 95 % of total domestic fuel requirement in the study area with more collection during summers but more consumption during winter months due to extensive drop in day and night temperatures. Fodder collection is a major practice adding a lot to women drudgery, and winter fodder deficit is a major issue that leads to dry fodder collection from remote locations. Similarly the average seasonal collection figures were also high for leaf litter ranging from 120 to 89 kg/household/day. Collection of wild edibles is moderate, while for medicinal plants is low in the study area. Resource availability, collection and consumption depend on the family size, distance from forest area and economic condition of the household. More than 95 % of the household’s biomass demands and requirement in the study area are fulfilled completely from forests, while rest are procured from various sources such as agroforests and agriculture.
