Building Local Community Commitment to Wetlands Restoration: A Case Study of the Cache River Wetlands in Southern Illinois, USA

Natural resource professionals are increasingly faced with the challenges of cultivating community-based support for wetland ecosystem restoration. While extensive research efforts have been directed toward understanding the biophysical dimensions of wetland conservation, the literature provides less guidance on how to successfully integrate community stakeholders into restoration planning. Therefore, this study explores the social construction of wetlands locally, and community members’ perceptions of the wetland restoration project in the Cache River Watershed of southern Illinois, where public and private agencies have partnered together to implement a large-scale wetlands restoration project. Findings illustrate that the wetlands hold diverse and significant meanings to community members and that community members’ criteria for project success may vary from those identified by project managers. The case study provides managers with strategies for building community commitment such as engaging local citizens in project planning, minimizing local burdens, maximizing local benefits, and reducing uncertainty.     

Investigation of amine amino acid salts for carbon dioxide absorption

The carbon dioxide capture potential of amine amino acid salts (AAAS), formed by mixing equinormal amounts of amino acids; e.g. glycine, β-alanine and sarcosine, with an organic base; 3-(methylamino)propylamine (MAPA), was assessed by comparison with monoethanolamine (MEA), and with amino acid salt (AAS) from amino acid neutralized with an inorganic base; potassium hydroxide (KOH). Carbon dioxide absorption and desorption experiments were carried out on the solvent systems at 40 °C and 80 °C respectively. Experimental results showed that amine amino acid salts have similar CO₂ absorption properties to MEA of the same concentration. They also showed good signs of stability during the experiments. Amino acid salt from an inorganic base, KOH, showed lower performance in CO₂ absorption than the amine amino acid salts (AAAS) mainly due to a lower equilibrium temperature sensitivity. AAAS showed better performance than MEA of same concentration. AAAS from neutralization of sarcosine with MAPA showed the best performance and the performance could be further enhanced when promoted with excess MAPA. The solvent comparison is semi-quantitative since the bubble structure, and thus gas–liquid interfacial area may not be the same for all experiments, however superficial gas velocities were kept constant.     

Tailor-made scenario planning for local adaptation to climate change

This paper presents a tailor-made scenario approach for climate change adaptation planning, which emphasises involvement of stakeholders in the development of socioeconomic scenarios and relates to the planning situation and interest of the planning entity. The method was developed and tested in case studies in three different sectors in Sweden (the health sector, the tourism sector and water resource management). The result of the case studies is that the tailor-made scenario approach facilitated the engagement of the local planning body in climate change adaptation and helped them to analyse consequences and possible solutions in a structured way. However, the scenarios that emerged mainly focused on socioeconomic drivers on which the planning body had a large impact or drivers that can be influenced through cooperation with other actors at the local or regional level. While this result underlines the need for local stakeholder involvement in scenario processes, it also indicates a local bias that could be remedied by a stronger representation of national and global perspectives in the scenario development process. Finally, we discuss how a “bottom-up” approach could be combined with a “consistency” approach, which points towards a possible way forward to a hybrid methodology that is compatible with the scenario framework currently being developed in connection to the fifth assessment report of the IPCC.     

World Stress Map of the Earth: a key to tectonic processes and technological applications

Modern civilisation explores and penetrates the interior of the Earth's crust, recovers from it and stores into it solids, fluids and gases to a hitherto unprecedented degree. Management of underground structures such as boreholes or reservoirs take into account the existing stress either to take advantage of it or at least to minimise the effects of man-made stress. This paper presents the World Map of Tectonic Stresses (in short: World Stress Map or WSM) as a fundamental geophysical data-base. The impact of the WSM is pointed out: in the context of global tectonics, in seismic hazard quantification and in a wide range of technological problems in industrial applications such as oil reservoir management and stability of underground openings (tunnels, boreholes and waste disposal sites).
