Abstract. The different aspects of carbon biogeochemistry were studied during the postmonsoon at the Hooghly-Sundarbans estuarine system, a part of the Ganga-Brahmaputra river system located in the northeastern India. The study focused on understanding the differences in carbon biogeochemistry of estuaries undergoing different levels of anthropogenic stress by investigating anthropogenically influenced Hooghly estuary and mangrove-dominated estuaries of the Sundarbans. The salinity of well oxygenated (%DO: 91–104 %) estuaries of the Sundarbans varied over a narrow range (12.74–16.69) during postmonsoon relative to the Hooghly (0.04–10.37). Phytoplankton productivity and carbonate precipitation and/or dissolution were dominant processes controlling DIC dynamics in different parts of the Hooghly, whereas signal for mangrove derived DIC removal was observed in the Sundarbans. Influence of groundwater on estuarine DIC biogeochemistry was also observed in both the estuaries with relatively higher influence at the Hooghly than Sundarbans. In both estuarine systems, DOC behaved non-conservatively with ~ 40 % higher DOC level in the Hooghly compared to the Sundarbans. No significant evidence of phytoplankton production on DOC level was found in these estuaries, however signal of DOC input through pore-water exchange at the Sundarbans was observed. Relatively lower δ13CPOC at the Hooghly compared to the Sundarbans suggest relatively higher terrestrial influence at the Hooghly with a possibility of in situ biogeochemical modifications of POC at the Sundarbans. The freshwater run-off coupled with in situ aerobic OC mineralization controlled estuarine pCO2 level at the Hooghly, whereas the same was principally exogenous for the Sundarbans. The entire Hooghly-Sundarbans system acted as source of CO2 to the regional atmosphere with ~ 17 times higher emission from the Hooghly compared to Sundarbans. The present study clearly establishes the dominance of anthropogenically influenced estuary over relatively pristine mangrove dominated one in the regional greenhouse gas budget and climate change perspective.

Rehabilitation Strategy

Mangrove management has been a sustainable concern in coastal wetlands for decades, especially for original near-shore wetlands and environments without mangrove forests. Although studies outlining environmental, social, and economic benefits of mangrove forests have been increasing, few studies have examined sustainability and policies for reducing or removing mangroves. This study explores the current implemented strategies pertaining to the invasion, conservation, and removal of mangroves for wetland sustainability. A total of 19 mangrove sites were sorted out to develop the main patterns and factors for the destruction or protection in estuaries on the western coast of Taiwan. For traditional wetland management, when faced with development pressure, having protected areas under certain laws is a good direction to go for mangrove sustainability. Furthermore, due to the invasion of mangroves in the mudflats, the Siangshan Wetland indicated mangrove removal can be a positive conservation case as an appropriate habitat rehabilitation strategy for benthic organisms. Under special conditions, mangrove removal provides useful insights into the sustainability of wetlands. These insights contribute to facilitating the worldwide move towards sustainable management on mangrove wetlands. The study also presents the following strategies to further reduce or remove mangroves in the coastal wetlands that contain no mangrove forests: (1) Conducting studies to evaluate the effectiveness of mangrove removal; (2) implementing policies to ensure positive influences on coastal wetlands, and (3) providing mangrove conservation education for sustainable development.

The Brahmaputra is one of the largest river systems of South Asia, providing life-supporting services to about 70 million people. Massive flooding, land erosion, over-exploitation of water, excessive fishing, habitat degradation and fragmentation, exploitation of flood plains, climate change impacts, absence of integrated basin wide management, and transboundary cooperation are major challenges for the present and future sustainability and development in the basin. Although hydrological connectivity is intact in most of the main course of the river, the infrastructure development plans may convert the Brahmaputra to a predominantly managed river system. In this regard, this paper examines the physiographic, ecological, hydrological, and socioeconomic status of the Brahmaputra river, its transnational basin in South Asia, and the basin population in the cross-cutting context to explore its sustainable management options. For a durable future of the river and its communities, an integrated management mechanism among the basin countries with the objective of equitable benefit sharing, disaster risk management, and resilience building is needed. The suggested strategies will help in maintaining the ecohydrological health and utilitarian services of the river for the socioeconomic development of millions of poor and marginalized people living in the basin.

Abstract Nothing is known about the population dynamics of Macrobrachium spp. or freshwater decapods in Palawan that hence received little attention to conservation studies that are imperative to establish sustainable management proposals. Thus, this paper provides information on the natural distribution and abundance of Macrobrachium spp. in Palawan to address threats to their survival. Preliminary findings through key informant’s interviews suggest the distribution and abundance of these species in Palawan’s river system. Generally, Macrobrachium spp. are present in all river systems in the province. However, the respondents observed that the population started to decline during the late 1990s attributed to the rampant use of organic pesticides/insecticides for agricultural purposes and intensive quarrying activities stretched along with the river systems in some of the municipalities in Palawan. Results also annotated that the local populations use these animals as food without official regulations, which may be additional pressure on freshwater prawns. The abundance of the Macrobrachium spp. is affected by human interventions and the destruction of their natural habitat and populations. Management measures should be considered from the economic conditions of freshwater prawns for effective management strategy and conservation efforts for future generations.

The Sundarbans

The Sundarbans is one of the oldest, contiguous, and systematically managed mangroves in the world. This biologically diverse ecosystem provides numerous benefits and services to local communities and the environment, however, it continues to remain under threat from population pressure, overexploitation, natural disasters and lack of practical policy regimes. This study assesses attitudes of local stakeholders towards sustainable management and conservation of mangrove forests as a means to assist planners, policy-makers, and decision-makers. A mixed-method approach was conducted to fulfill the objectives of this study. The study reveals that the people of the Sundarbans Impact Zone are highly dependent on the Sundarbans for their livelihood. Indeed, collecting resources from both aquatic and terrestrial areas is considered a traditional right. As such, people are increasingly becoming more conscious about government policy, and they want the forest to be managed sustainably. Generally, the language of governance is very strong, but many argue that implementation of policy is difficult because of competing policies, weak infrastructure, inefficiencies, illegal approaches, and corruption. Efforts should be made to develop and advance coupled human-environment (socio-ecological) systems that call for more participatory management approaches. Wider participation and ‘empowerment’ of stakeholders would improve the governance of the Sundarbans and ensure common priorities and levels of agreement on both conservation and livelihood issues.
