Ecosystem Services Assessment for the Conservation of Mangroves in French Guiana Using Fuzzy Cognitive Mapping

In 2016, the French government adopted a law for biodiversity, setting an objective of protecting 55,000 hectares of mangroves. This objective is particularly important to French Guiana, which shelters almost 60% of French mangrove ecosystems, and where mangroves occupy three quarters of the coastline. The coast of French Guiana is also where issues associated with demographic and economic dynamics concentrate. There is thus a need to plan for an economic development that is compatible with the objective of protecting mangrove ecosystems. Ecosystem services (ES) assessment can support such decision-making, informing on the costs and benefits associated with alternative mangrove conservation strategies. While the many services provided by mangrove ecosystems are well documented worldwide, the extent to which these can be encountered in the specific case of French Guiana is currently only very partially known. Relying on the Fuzzy cognitive mapping (FCM) approach, we collected and compared the perception of multiple and heterogeneous groups of stakeholders, of the functioning of the mangrove social-ecological system at the scale of French Guiana. Results, allow to identify mangroves ES and threats particularly influenced by the high sedimentary dynamism of the shoreline. This generates two distinct components of the mangrove social-ecological system: mud banks where ecosystem services are spatially and temporally unstable, and associated with perceived constraints for key coastal activities, and estuarine mangroves where the ecosystem services usually described in the literature on mangroves can be found. Disservices associated with mangrove ecosystems were also identified as a key interaction. This can inform the research needs that should support sustainable development trajectories, fully accounting for the protection of French Guianese mangrove ecosystems.

Pestering Capitalism. Thinking with Halyomorpha halys about multispecies relations and ecological unsustainability

Many non-human species trouble human-oriented forms of multispecies life, which leads to classifying some of these species as pests. One of the fields of daily life most disturbed by the action of pests is modern capitalist agriculture, leading to different types of pest management by which human beings attempt to eliminate pests’ opposition to the anthropogenic appropriation of the work/energy of multispecies assemblages, an appropriation which is essential for capital circulation. In dominant modern capitalist cosmologies, the disturbances caused by pests automatically justify and require their attempted extermination. Without denying that pests are troubling, I argue that the technoscientific framing of our relationship with these species is insufficient as a way of understanding and interacting with them. Rather than exclusively seeing pests as a problem, the manner in which humans interact with these species points us to several foundational - and in themselves problematic – aspects of modern capitalist world-ecology. Taking my research on networks concerned with kiwifruit farming and commercialization in Portugal as a basis for my arguments, I look at how actors in these networks propose to deal with Halyomorpha halys, the brown marmorated stink bug, in an attempt to think with this species about the (inextricably connected) socio-ecological unsustainability of modern capitalist world-ecology and the bio-thanato-political strategies of immunization employed to deal with non-human species in this political ecological system.

Matrix Effects on the Performance and Mechanism of Hg Removal from Groundwater by MoS2 Nanosheets

Mercury (Hg) contamination in groundwater has been recognized as a serious threat to human health and ecological system all over the world. This study demonstrated two-dimensional (2D) molybdenum disulfide (MoS2)...

A Comparative Study of the Factors Associated with Geriatric Depression between Two Sex Groups Living Alone

Purpose: The aims of this study were to identify depression rates depending on the sex among elderly people living alone and to compare depression-related ecological system factors between two sex groups.Methods: A cross-sectional study was conducted using secondary data from the 7th Korean Longitudinal Study of Aging survey in 2018. A total of 893 elders living alone were included (152 men and 741 women). Hierarchical logistic regression was used to identify depression-related ecological system factors depending on the sex.Results: Men had significantly higher rates of depression (28.6%) than women (24.0%, p<.001). Depression-related ecological system factors in elderly women were higher educational level, poor subjective health status, impairment of instrumental activities of daily living, low satisfaction with children’s relation, financial based on children’s support, and rare meetings with close people. However, relation satisfaction with children was the only relevant depression-related ecological system factor in the men’s group.Conclusion: Our study findings show that depression-related ecological system factors vary depending on the sex of elderly people living alone. Thus, mental health professionals should provide sex-specific interventions to develop or implement depression-prevention strategies for the elderly living alone depending on the sex.

Discourse for Transition toward Sustainability Development in Industrial Ecology Context in Kutai Kartanegara

A rich ecological value area within East Kalimantan, Kutai Kartanegara, represents a specific-particular ecological system of an island in a tropical country. Covered by the evergreen forest in the past, it has a closed-loop system formed naturally due to its metabolism. This system maintains the high diversity of nature which provides abundant resources both renewable and non-renewable. Owing to its ecological system value, the earth has been numerous beneficial the economic sector both for country and region for decades. Let say coal is one of the attractive resources for the energy sector, which has been contributing over 80% of the GDRP of Kutai Kartanegara in 2010.

Exploring Values and Beliefs in a Complex Coastal Social-Ecological System: A Case of Small-Scale Fishery and Dried Fish Production in Sagar Island, Indian Sundarbans

The survivability of the small-scale fishery and dried fish production in Indian Sundarbans, despite increasing threats posed by climate, environmental, economic, and policy drivers, suggests that they possess certain unique strengths and capabilities. One thread of these strengths is connected to the fact that Sundarbans’ fishery system is strongly anchored in the values and beliefs of the local fishing communities. There is, however, limited empirical information available on the prevailing individual and collective attitudes, expectations, traditions, customs, and, above all, values and beliefs that strongly influence local fishing communities of Sundarbans. This manuscript aims to address this gap by drawing on qualitative data to (1) map the nature of values and beliefs associated with the Sundarbans’ Sagar Island fishing communities who are engaged in small-scale fishery and dried fish production; and (2) highlight the contributions of values and beliefs to the small-scale fishery and dried fish production systems of Sagar Island. Our study reveals that historical factors such as the patriarchal and patrilineal system prevalent in the Indian Sundarbans as well as the current drivers, including environmental and social-economic changes, create inconsistent values and beliefs among male and female members of its society. Issues around values and beliefs are heavily influenced by social-ecological realities comprising material, relational and subjective dimensions. They can range from being strictly personal to largely community-oriented as they are shaped by realities of gender, class, power dynamics, and politics. Values and beliefs are fundamental to human perception and cognition but often get neglected in mainstream literature covering human dimensions of resource management. Our research adds weight to the theoretical and place-based understanding of the contributions of values and beliefs to the small-scale fishery and dried fish production systems. We learn from the case study that values and beliefs can act as mirrors, reflecting the current as well as future realities of small-scale fisheries and dried fish production systems and provide important directions for sustainability and viability of the entire social-ecological system that hosts this sector.
