Rationale for Decision-Making Processes in Enhancement of Community Participation for Sustainable Mangrove Management in Lamu, Kenya

Decision-making is the process of deciding between two or more options in order to take the most appropriate and successful course of action in order to achieve sustainable mangrove management. However, the distinctiveness of mangrove as an ecosystem, and thus the attendant socio-economic and governance ramifications, causes the idea of decision making to become relatively distinct from other decision making process As a result, the purpose of this research was to evaluate the impact that community engagement plays in the decision-making process as it relates to the establishment of governance norms for sustainable mangrove management in Lamu County. In this study, a correlational research design was applied, and the researchers employed a mixed techniques approach. The target population was 296 respondents. The research used questionnaires and interviews to collect data. A descriptive statistical technique was utilized to perform an inspection and analysis on the data that was gathered. The findings indicated that having awareness about governance standards is beneficial during the process of making decisions. In addition, the findings demonstrated that respondents had the impression that the decision-making process was not done properly. On the other hand, the participants pointed out the positive aspects of the decision-making process and agreed that the participation of both gender was essential for the sustainable management of mangroves. Based on these data, it appeared that full community engagement in decision-making is necessary for sustainable management of mangrove forests.

Testing of Decision Making Tools for Village Land Use Planning and Natural Resources Management in Kilimanjaro Region

This paper focuses on participatory testing of decision making tools (DMTs) at village level to assist in development of land use plans (LUPs) for sustainable land management (SLM) in Kilimanjaro Region, Tanzania. Data were collected using conditional surveys through key informant interviews with the project’s district stakeholders in each district, focused group discussions with selected villagers and participatory mapping of natural resources. Soil health, land degradation, carbon stock, and hydrological conditions were assessed in the seven pilot villages in all seven districts using DMTs as part of testing and validation. Results indicated soils of poor to medium health, and land degradation as portrayed by gullies and wind erosion in lowlands and better in uplands. Carbon and forest disturbance status could not be assessed using one-year data but hydrological analysis revealed that water resources were relatively good in uplands and poor in the lowlands. Challenges with regard to land use include increased gully erosion, decreased stream flow, reduced vegetation cover due to shifting from coffee with tree sheds to annual crops farming, cultivation near water sources, and overgrazing. Empowering the community with decision making tools at village level is essential to ensure that village land uses are planned in a participatory manner for sustainable land and natural resources management in Kilimanjaro and other regions in Tanzania.

Development of an Effective System for Selecting Construction Materials for Sustainable Residential Housing in Western Australia

Urbanization and living comfort have revolutionized the construction industry. Many techniques and strategies have been used to improve the overall efficiency of construction and to reduce waste during and after the construction activity;some are cost effective and some not. Sustainable construction strategies have addressed these issues by proposing relatively more cost effective and environment-saving solutions. One strategy is to select sustainable construction materials at the building design stage. This article involved a questionnaire survey to collect data about local technical stakeholders’ (architects, designers, engineers, estimators, and managers) awareness of environmental sustainability and current practices for selecting construction materials. A sustainability index (SI) was developed using SPSS (Statistical Package for the Social Sciences) for the complex statistical analysis. These data were used to develop a decision support system (DSS) using the multi-criteria decision making (MCDM) technique, the TOPSIS. The support system was validated by applying it to sustainable roof products in a pilot case study—these materials are frequently used in local markets for residential construction in West Australia. So the main objective was to get insight to local market trends and features involved in construction materials selection. Data analysis was carried out to develop a decision support system to help technical stakeholders in construction materials selection process.

Economic and environmental sustainability assessment of wine grape production scenarios in Southern Italy

The low resilience of ecosystems imposes a sustainable management of natural resources through more rational uses, land protection, energy saving and low carbon production technologies. Agriculture has a great responsibility in managing these resources that are the principal inputs of its processes. Production systems must pay attention, at the same time, to economic viability and environmental protection. Since decades, the international scientific community is facing the great challenge of assessing the sustainability of agricultural engineering techniques, in order to help both private and public decision making, but also to meet consumer’s requirements for high quality and low impact products. To achieve that, widely accepted assessment instruments, whose results have to be clear and understandable to a broad public, and that are necessary. In this direction, Life Cycle Thinking (LCT) is gaining consensus as conceptual model, considering goods and services production and consumption all along the whole life cycle, from planning to disposal. Its methodological frame- work, the Life Cycle Management (LCM), offers many standardised tools to assess impacts of products and processes: Life Cycle Assessment (LCA), to evaluate environmental impacts and Life Cycle Costing (LCC) for economic ones. Among many impacts categories LCA also allows to identify the carbon footprint, that can be quantified in terms of Global Warming Potential (GWP). This research has analyzed and compared different scenarios of wine grapes production in Cirò, an important viticultural area located in Calabria region (Southern Italy). LCA and LCC methodologies have been useful to assess them from an environmental and economic standpoint. Results have allowed the authors to rank training and farming systems performances.

Mechanism for Integrating Sustainability in Engineering Design

This paper proposes an integration mechanism to help the owners and designers to integrate sustainability issues into design process, communicate with stakeholders and achieve consensus. Literature concerning engineering design, decision making and environment assessment were reviewed. Sustainability disputes in construction projects were analyzed and owners and designers were interviewed to understand the evolvement of these issues. Key success factors of other successful integration projects were also referenced. An integration mechanism including procedures was established along with traditional design process. Four integration steps were developed： organize integration team, propose integration issues, determine acceptance criteria, and evaluate alternatives; and four integration dimensions were also identified： appeals, decision making and execution, stakeholders, and experts. A matrix was formed by the four integration steps and four dimensions. A rigor index was proposed to measure the quality of the integration process. Finally, the mechanism was tested on a construction project with sustainability controversy to check its validity. The study results show that the integration mechanism can help incorporate sustainability issues and achieve consensus if followed rigorously. The integration matrix systematically examines the eight key integration factors under the four dimensions. The rigor index can explain the quality in integrating sustainability issues into engineering design. The mechanism provides a useful tool for the owners and designers to cope with the sustainability decision making difficulties.

Design Drivers for Affordable and Sustainable Housing in Developing Countries

Current demand for housing worldwide has reached unprecedented levels due to factors such as human population growth, natural disasters and conflict. This is felt no more so than in developing countries which have experienced disproportionate levels of demand due to their innate vulnerability. Many current approaches to housing delivery in developing countries continue to utilize inappropriate construction methods and implementation procedures that are often problematic and unsustainable. As such affordability and sustainability are now vital considerations in the international development debate for housing the poor in developing countries in order to meet the long term sustainable development goals and needs of housing inhabitants. This paper utilized an extensive scoping study to examine the various facets impacting on design decision making relative to sustainable and affordable housing delivery in developing country contexts. Aspects of affordability, sustainability, design decision making, appropriate technology use, cultural awareness, as well as current barriers to affordable and sustainable construction in developing countries are examined in detail. Results highlighted the capability of indigenous knowledge, skills and materials as well as selected appropriate technology transfer and cultural awareness by foreign bodies can be utilized in innovative ways in addressing current housing needs in many developing country contexts.

Tourism Entropy as a Critical Factor for Destination Sustainability:Assessment of Carrying Capacity Through IoTs and Determination of Tourism Satisfaction

This paper introduces a novel methodology to address the issue of destination carrying capacity assessment and monitoring,while,to develop a new tool to enable effective and optimized policy making in tourism sector.Tourism fits together a chain value,where stakeholders are working as cogwheels targeting the sustainability.An inherent requirement towards the objectives of sustainability is the capacity of policy makers to sustain the available social,economic,and environmental resources.Given the facts that(i)carrying capacity is a complex,dynamic,multidimensional concept,apparently vague,as such it is quite difficult to assess and monitor and(ii)each destination has unique characteristics,varying the extent and intensity of tourism development,the research proposal refines and implements measures and establishes a state-of-the-art data collection network in order to monitor tourism development in terms of sustainability and to establish an integrated carrying capacity estimation framework.Since validity and reliability of input data is a critical issue,different kind of sensors for environmental data(IoTs)are used,as well as web mining methods and field surveys,statistical information and secondary research results.Also,specialized analysis methods are applied and integration of all sources is achieved,defining the characteristics of the tourism destination ecosystem from the perspective of entropy change,in order to provide planning,policy making,and decision support,as well as a set of intelligent tools.

How Much Tourism Is Too Much? Stakeholder’s Perceptions on Overtourism, Sustainable Destination Management During the Pandemic of COVID-19 Era in Santorini Island Greece

The newly adapted concept of“overtourism”based on the old concept of carrying capacity has emerged in various destinations worldwide and it seems to be one of the most important issues on destination management literature.Santorini is one of the most picturesque islands globally and at the same time one of the destinations that have been incorporated into the discourse of overtourism.However,Santorini is different to many of the destinations exposed to overtourism as an island destination with specific limitations in physical space,natural and physical resources.For many years we have experienced the rapid growth of tourism worldwide until the emergence of the COVID pandemic that stopped almost every economic activity.The rapid increase of visitors in Santorini had various impacts on the island’s economy,society,and environment.This paper is about overtourism on the Aegean Island of Santorini,where overtourism has been a fact for several years.In the island tourism development is evident but sustainability is a critical theme for the locals,the entrepreneurs,and the tourism industry of the destination.In this paper the perceptions of the destination’s stakeholders are examined on issues like sustainability,overtourism,and the impacts of the pandemic.Finally,the paper examines the stakeholders’thoughts on the possibility of the pandemic might become the springboard for redefining tourism on the island.
