Mangrove forests have been studied broadly in the recent three decades for their outstanding ability to sequester carbon in the beneath soil and other beneficial ecosystem services. Endeavors to conserve and regenerate mangrove cover are still increasing worldwide as a mechanism to include them in NDCs and carbon markets. Therefore, decision-makers in the private and public sectors require identify possible areas for conservation and restoration prior to blue carbon project investment. Thus, an integral assessment of potential mangrove carbon reservoirs in a landscape scale, considering environmental and socioeconomic factors was performed. This study was aimed to determine areas with the highest blue carbon sequestration potential in the Gulf of Guayaquil through the construction of a Blue Carbon Potential Index (BCPI) based on Spatial Multicriteria Analysis (SMCA). A narrative integrative literature review was employed to select indicators of mangrove carbon sequestration gains and losses. These indicators were pondered following the Analytical Hierarchy Process (AHP) with the judgments of two experts and reclassified in four potential categories based on their thresholds. Since no consensus was achieved in the indicator importance hierarchization, a comparative of equal weighting method and AHP weighting was implemented. The linear combination rule was used to integrate these factors into a unique-scaled index supported by a geographic Information System (GIS). The results showed that 15.82% and 16.21% of the study area belonged to high and moderate potential of blue carbon sequestration respectively. Moreover, no significant differences were found between the two weighting methods applied. The BCPI provides a comprehensive understanding of spatial distribution of blue carbon potential reservoirs and grants a quantification of this potential to prioritize conservation and restoration areas.
Catastrophe insurance without premium payment – The concept of contigent liability in Switzerland
(2023)
No later than with the heavy rainfalls of 2021, discussions in Germany have resumed around the introduction of compulsory insurance for natural hazards. Natural hazards exhibit a high potential for loss, and insurance is a building block with which to bolster resilience. In practice, there are already a host of functioning solution concepts to provide cover for natural hazards, including insurance pools and state guarantees. All of the concepts, however, are predicated on payment of an ongoing insurance premium.
Agents with antifungal activity play a vital role as therapeutics in health care, as do fungicides in agriculture. Effectiveness, toxicological profile, and eco-friendliness are among the properties used to select suitable substances. Furthermore, a steady supply of new agents with different modes of action is required to counter the well-known potential of human and phyto-pathogenic fungi to develop resistance against established antifungals. Here, we use an in vitro growth assay to investigate the activity of the calcineurin inhibitor tacrolimus in combination with the commercial fungicides cyproconazole and hymexazol, as well as with two earlier reported novel {2-(3-R-1H-1,2,4-triazol-5-yl)phenyl}amines, against the fungi Aspergillus niger, Colletotrichum higginsianum, Fusarium oxysporum and the oomycete Phytophthora infestans, which are notoriously harmful in agriculture. When tacrolimus was added in a concentration range from 0.25 to 25 mg/L to the tested antifungals (at a fixed concentration of 25 or 50 mg/L), the inhibitory activities were distinctly enhanced. Molecular docking calculations revealed triazole derivative 5, (2-(3-adamantan-1-yl)-1H-1,2,4-triazol-5-yl)-4-chloroaniline), as a potent inhibitor of chitin deacetylases (CDA) of Aspergillus nidulans and A. niger (AnCDA and AngCDA, respectively), which was stronger than the previously reported polyoxorin D, J075-4187, and chitotriose. The results are discussed in the context of potential synergism and molecular mode of action.
The internal armed conflict in Colombia has been closely linked to the illegal exploitation of natural resources and the appropriation of territories, including the planting of illicit coca crops. This activity has led to deforestation and the degradation of natural ecosystems, aggravating the problems associated with violence and drug trafficking. Regions with little state presence, such as Catatumbo, were particularly affected.
Following the signing of the peace agreement with the Revolutionary Armed Forces of Colombia (FARC) in 2016, a post-agreement scenario emerged that highlighted the need to address complex socio-environmental conflicts in affected regions. This research aims to identify the potential of environmental governance to contribute to peacebuilding and the reduction of deforestation associated with illicit coca cultivation.
A qualitative methodological approach was used in this study, which seeks to integrate research methods and techniques such as: documentary review, participant observation, semi-structured and in-depth interviews, and mapping of the current reality through the Theory U 3D mapping tool.
The results include the socio-environmental context of the territory of analysis, describing the origins of the conflict of deforestation for illicit crops, where the growing dynamics of transformation of the sowing of illicit crops are related, as well as the dynamics of deforestation in the territory of analysis. Tthe identification and analysis of the most relevant actors that have historically participated in the processes of deforestation for illicit crops, their characterization according to the relations of power, interest and legitimisation legitimization. The forms of participation and conflict resolution in the management of natural resources.
Considering as a contextual axis two important processes at a socio-political level in Colombia and the territory under analysis, which correspond to the consolidation of the Comprehensive Rural Reform after the peace agreement and the post-agreement context. Several intervention proposals were proposed from the perspective of environmental governance related to the reconstruction of the social fabric, the reconversion of productive systems, and the resignification of new dynamics of natural resource management. In this sense, the potential of environmental governance is discussed as a useful framework for establishing new relationships based on horizontality in which the actors possess sovereignty over the territory, participation and representativeness in the management of natural resources.
Key words: Deforestation, illicit coca crops, environmental governance, forest management, peacebuilding.
Ten years after the journal’s first publication, we are taking a closer look at the knowledge flows of the output of the journal Publications. We analyzed the papers, topics, their authors and countries to assess the development of scholarly communication within Publications. Our bibliometric analyses show the research journal’s community, where the knowledge of this community is coming from, where it is going, and how diverse the community is based on its internationality and multidisciplinarity. We compare these findings with the scopes and topical goals the journal specifies. We aim at informing the editors and editorial board about the journal’s development to advance the journal’s role in scholarly communication. The results show that regarding topical diversity and internationality, the journal has remarkably developed. Moreover, the journal tends towards the field of library and information science, but strengthens its multidisciplinary status via its topics and author backgrounds.
