Full textAbstract:
With the Clean Energy Package, the European Union introduced the concept of Renewable Energy Communities: groups of citizens, small and medium enterprises and local authorities that decide to join forces to equip themselves with systems to produce and share energy from renewable energy sources. The Italian legislation recently started an experimental phase in which renewable energy communities receive an incentivising tariff for the energy produced and shared within the community. This paper faces the problem of creating a new renewable energy community in two steps. First, a mathematical model of the energy flows among the members of the community is characterised according to the Italian schema. This model is used to find the optimal portfolio for the energy community, given energy requests and local source availability. Secondly, the Shapley value, a particular solution of cooperative games known to be the most fair method to allocate costs and profits of shared infrastructures, is proposed to distribute benefits among community members. The methodology has been applied to a case study based on a real low voltage network, and the economics for consumers and producers in participating to the project have been evaluated. The proposed solution, simulated adopting real economic parameters defined in the Italian regulatory framework, results to be economically viable from the point of view of the investors with a profitability index of 1.36 and, at the same time, aligned with the social purposes of the energy communities.

Full textAbstract:
The current paper contributes to the literature on community renewable energy by considering two projects developed in the north-west of Italy, in the Piedmont region. Community renewable energy is increasingly regarded by academic literature and policy discourse as crucial to ensure a socially and environmentally just energy transition. In spite of the growing diffusion of community renewable energy projects, there is still a lack of theoretically informed analyses. Our article tries to address this gap by combining two theoretical perspectives: the multilevel perspective and the socio-technical imaginaries approach. Applying the first perspective helps reconstruct the context and circumstances that have permitted the Piedmont’s energy community projects to emerge. Particular attention is given to the windows of opportunity created by the Regional Law 12/2018, which acknowledged the establishment of energy communities for the first time in Italy. The socio-technical imaginaries perspective allows the identification of collective ideas and meanings that emerge when individuals or groups promote a socio-technical innovation. Based on this analysis, three main future changes are associated with community renewable energy: an integral ecology approach, a stronger sense of community, and a local development opportunity for rural areas characterised by depopulation, a low employment rate, and high energy demand.

Full textAbstract:
Community energy is seen as a helping hand for local, decentralized energy transition. Besides the main goal of supporting the community-friendly and socially acceptable development of renewable energies, the hope is also that a pro-environmental influence on sustainability behavior will be triggered when joining a community energy project. An analysis of a survey among 16 community energy projects in Germany, with 565 completed questionnaires, shows that a certain part of the members pays more attention to their energy behavior and develop a more positive attitude towards a decentralized energy transition and citizen participation after joining the community energy project. Therefore, we can empirically support that climate protection projects, such as community energy, influence pro-environmental attitudes and behavior, but this does not apply equally to all population groups. Members with higher income and stronger interest in returns are less likely to change their behavior. Based on these findings, we recommend the development of community energy policies that are more responsive to differences in social structure and address both privileged and underprivileged groups in a sophisticated way using specific offers and modes of involvement within the associations.

Full textAbstract:
Community renewable energy (CRE) has recently been proposed as one of the effective policy tools to make a community sustainable and to strengthen this association. CRE is, however, not widespread yet in Thailand, and evidence-based research on CRE in the country is rather scarce. This paper aims to investigate the characteristics of CRE in Thailand to identify the key factors affecting its implementation. Data were collected through semi-structured interviews and document analysis for 26 active CRE projects in Thailand. Results show that the characteristics of CRE in Thailand are rooted in the geographical location of a community. A legal structure was created from a pre-existing group to implement a CRE project. The primary motivation for implementing CRE is sustainable development of a community. We examined essential factors separated into two groups—internal and external factors—in reference to CRE in developed nations. We highlight several issues concerning the further development of CRE in Thailand. First, a strong group leader and a formal structure are essential to drive and manage a project. Second, networks of CRE projects and long-term revolving funds are crucial external support to implement CRE.

Energy policy in the world has changed due to the climate crisis. As a result, the need for renewable energy supply is increasing. Trees in the forestry sector are a reliable source of biomass for renewable energy production. Community forests could play an important role in supplying biomass-based renewable energy production. The study aims to understand the attitude, subjective norms, and perceived behavioural control on Farmers Forest Group's intention in cultivating trees for energy in Yogyakarta Province. The Theory of Planned Behaviour approach was used to analyse the correlation between Attitudes, Subjective Norms, and Perceived Behavioural Control on Forest Farmers Group Intention in cultivating trees for renewable energy. A survey using an online questionnaire was conducted on Forest Farmers Groups in four districts in DI Yogyakarta; Sleman, Kulonprogo, Bantul, and Gunungkidul. The survey results were analysed using non-parametric statistics.The results showed a significant positive correlation between Attitudes, Subjective Norms, and Perceived Behavioural Control on the Forest Farmers Group's Intention to cultivate trees for renewable energy. The study provides policymakers and privates with insight into working with the farmers when they are about to implement biomass-based renewable energy programs

Full textAbstract:
Blockchain, or distributed ledger, is an innovative technology that is emerging in various sectors and industries across the globe. It has attracted the attention of different interest groups such as energy companies, SMEs and start-ups, information technology developers, financial institutions, national authorities, and the university community. Through, for example, the decentralization of authority in transactions, Internet of Things (IoT) implementation, and smart contracting, the improvement of the daily business operations is firmly forecasted. In the energy sector, digitalization is already present in solutions such as smart grids, smart meters, electric vehicles, etc. Moreover, a new concept of the Internet of Energy (IoE) has been introduced in the academic literature. In this article, the level of trust and maturity of Blockchain technology implementation is investigated through the Blockchain Maturity Questionnaire, developed by the authors. The database consists of responses from upper management professionals from the renewable energy industry. The analysis reveals the state of know-how about Blockchain, the main benefits and bottlenecks associated with its implementation as well as willingness to integrate this technology in the case companies’ future operations. The insight from the industry experts helped to provide a “Roadmap for Blockchain Adoption” in future energy systems. This curiosity study yields numerous applications not only for the renewable energy industry experts but also for the interest groups coming from different industries, as well as public authorities and researchers scrutinizing the fields taken into its scope.

ObjectiveTo examine the forms, scale and role of community and voluntary support for community hospitals in England.DesignA multimethods study. Quantitative analysis of Charity Commission data on levels of volunteering and voluntary income for charities supporting community hospitals. Nine qualitative case studies of community hospitals and their surrounding communities, including interviews and focus groups.SettingCommunity hospitals in England and their surrounding communities.ParticipantsCharity Commission data for 245 community hospital Leagues of Friends. Interviews with staff (89), patients (60), carers (28), volunteers (35), community representatives (20), managers and commissioners (9). Focus groups with multidisciplinary teams (8 groups across nine sites, involving 43 respondents), volunteers (6 groups, 33 respondents) and community stakeholders (8 groups, 54 respondents).ResultsCommunities support community hospitals through: human resources (average=24 volunteers a year per hospital); financial resources (median voluntary income = £15 632); practical resources through services and activities provided by voluntary and community groups; and intellectual resources (eg, consultation and coproduction). Communities provide valuable supplementary resources to the National Health Service, enhancing community hospital services, patient experience, staff morale and volunteer well-being. Such resources, however, vary in level and form from hospital to hospital and over time: voluntary income is on the decline, as is membership of League of Friends, and it can be hard to recruit regular, active volunteers.ConclusionsCommunities can be a significant resource for healthcare services, in ways which can enhance patient experience and service quality. Harnessing that resource, however, is not straight forward and there is a perception that it might be becoming more difficult questioning the extent to which it can be considered sustainable or ‘renewable’.

Full textAbstract:
Peer-to-peer (P2P) energy trading is emerging as a new mechanism for settling the exchange of energy between renewable energy generators and consumers. P2P provides a mechanism for local balancing when it is facilitated through distributed ledgers (‘blockchains’). Energy communities across Europe have uncovered the potential of this technology and are currently running pilots to test its applicability in P2P energy trading. The aim of this paper is to assess, using legal literature and legislation, whether the legal forms available to energy communities in the United Kingdom (UK) can help resolve some of the uncertainties around the individual use of blockchain for P2P energy trading. This includes the legal recognition of ‘prosumers’, the protection of their personal data, as well as the validity of ‘smart contracts’ programmed to trade energy on the blockchain network. The analysis has shown that legal entities, such as Limited Liability Partnerships and Co-operative Societies, can play a crucial role in providing the necessary framework to protect consumers engaging in these transactions. This is particularly the case for co-operatives, given that they can hold members liable for not respecting the rules set out in their (compulsory) governing document. These findings are relevant to other European countries, where the energy co-operative model is also used.

Full textAbstract:
Renewable Energy Communities (REC) are an emerging initiative that aims to contribute to the energy transition towards a more decentralised system in Europe by encouraging local communities to come together and invest in and operate renewable energy assets together.Decision-making processes of these communities need to be supported by adequate tools, which also can be used in the formation of the community groups in the first place. In this paper a case-study of four European small-town communities in Berchidda (Italy), Ollersdorf (Austria), Ispaster (Spain), and Kökar (Finland) carried out in the context of the LocalRES project is presented, where a participatory design methodology has been applied to co-create community supporting tools. Feedback gathered during four citizen workshops is presented, showing that to optimally support RECs in their formation and operation three main topics need to be supported: (1) the technical realisation and potential upgrades of the energy system, i.e., visualising energy generation and consumption on an individual and a community level, (2) the financial and economic implications of investments, i.e., calculating costs and return on investment for the individual and for the community, as well as (3) the social dimension and communication between community members and other relevant stakeholders, i.e., helping with community building and community engagement. The participatory process presented in the case studies does not only serve to gather requirements for tool design, but it also is a useful vehicle to bring together all interested citizens and understand their needs and concerns. A summary of this detailed citizen feedback is also presented.

Full textAbstract:
An essential component in sustainable energy development is the production of bioenergy from waste. The most successful bioenergy technology worldwide is anaerobic digestion (AD), which is a microbially-mediated process of organic feedstock conversion into energy-rich compounds (volatile fatty acids (VFA) and biogas) for renewable energy generation. AD is deployed in a range of situations including systems for on-farm energy recovery from animal and plant waste to the processing of food and municipal solid waste (with the additional benefit of land-fill reduction).Anaerobic digesters rely on a diverse microbial community working syntrophycally through a series of interrelated biochemical processes.Each stage in anaerobic digestion is carried out by different microbial groups. Thus, to optimise energy recovery from the AD process, the microbial community must have stable performance over time, balancing the various metabolic functions and taxonomic community composition in digesters. Complicating this balance, it has been found that the presence of ammonia, sulphate, and hydrogen sulphide in substantial concentrations often cause failure in the AD process. Thus, these substances cause adverse shifts in microbial community composition and/or inhibit bacterial growth, that influencing AD performance. ©2020. CBIORE-IJRED. All rights reserved

Shrimp is very promising commodity of the Indonesian export commodities. One of shrimp cultivation fields is pond which is a place of aquaculture located near the beach. Application of renewable energy sources such as photovoltaic cell technology has been prepared to provide energy supply integratedly in the shrimp ponds in Pinrang District of South Sulawesi. Energy needed in the shrimp ponds is to provide energy supply for some supporting equipments such as aerator water mill, lighting, water pump, and others. Community empowerment activity was carried out in order to empower communities in Pinrang District of South Sulawesi in application of renewable energy resources in their shrimp ponds. This activity was arranged in self supporting energy concept in the shrimp pond and supported by a program of <em>Kuliah Kerja Nyata–Program Pemberdayaan Masyarakat</em> (KKN-PPM) DIKTI. Equipment manufacture of photovoltaic cell prototype as energy sources of aerator waterwheel and lighting in the shrimp pond has been completed. Some community groups of shrimp farmers have been trained in the manufacture and operation of the photovoltaic cell equipment.

Full textAbstract:
Limitations and scarcity of natural energy resources has forced the government to develop new renewable energy, one of them by making a pilot hybrid power plant project or Pembangkit Listrik Tenaga Hybrid (PLTH) in coast Pantai Baru, Pandansimo, Bantul. It is an innovative attempt at once problematic, innovative efforts appear because electricity that facilitated community and business opportunity to improve their welfare. Instead, the change still leaves the problem and contestation among stakeholders. Vulnerable groups like women are the groups that most affected by such change. They perform a dual role at the domestic level as well as the public, unfortunately these changes make them as objects rather than subjects of the new renewable energy projects. An effort to shift the women from the position of an object to be the subject of renewable energy is not easy task. In response, the methodological attempt to do is to choose action research to strengthen women as agents of change in the post-construction PLTH. The result, although not all involved, a group of coastal women can no longer be considered vulnerable, but it has become one of the new strengths of coastal communities around PLTH.

Full textAbstract:
Work on the design and implementation for solar homes has been expanded to the community scale in several international projects. If low-carbon emission housing is to make an impact on citywide consumption of energy, we must move towards community-scale implementation of solar technologies, both in new housing developments and in existing ones. However, the uptake of solar communities requires new methods for implementation to promote innovation in the building industry, new policies and programmes on energy consumption and energy subsidies, as well as community-scale design guidelines for solar or other renewable technologies. This research surveys the implementation process of selected solar community projects in Netherlands, United States and Canada. It looks at new policies and programmes that are promoting community-scale solar projects from the perspective of innovation in the building industry. It examines the various actors that are necessary for solar communities within an urban planning framework and identifies five main actor groups.

Full textAbstract:
Like many other sectors, climate change strategies have put various restrictions on industry, the most prominent one being caps on CO2 and other energy-related emissions. At the same time, and especially in many developing economies, the industry struggles with an increasing gap between the fast development of the sector and lagging energy supply capacity. Collective generation of renewable energy is seen as a promising means of transition, next to other forms of renewable energy generation (centralised, individual). The aim of this research is to investigate factors influencing willingness to participate in Industrial Community Energy Systems (InCES). Using existing literature on Industrial Symbiosis and Community Energy Systems, we formulate plausible hypotheses on the most relevant factors for the willingness of industries to join such initiatives. As one of the largest and most diversified industrial clusters in Iran, Arak industrial park is selected as the case study. Data were collected from the CEOs of 96 companies through survey research. Our results highlight the crucial role of awareness about the benefits of renewable power generation in an InCES. Social identity among industries and trust between them are also determining factors for their willingness to join InCES. Finally, proper institutional design for overcoming the partnership complexities (e.g., conflict resolution) was highlighted as a crucial factor for industries. It can be concluded from the results of this study that policymakers should avoid one-size-fits-all incentive design approaches and reach out to larger companies with targeted incentives, introduce specially designed bank loans for different target groups, and make use of consulting companies as intermediaries to increase the awareness of the industries regarding the benefits of investing in an InCES.

Full textAbstract:
This paper addresses the current status and future research and development perspectives associated with technologies to harness offshore renewable energy, including offshore wind, waves, tides, ocean currents, and thermal and salinity gradient, in South America (SA). It focuses on five countries: Argentina, Brazil, Chile, Colombia and Uruguay. At first, a comprehensive survey presents the number of scientific papers classified based on the resource to show the tendency and importance of such subjects in the academic community. Each country’s electricity matrix and grid connection are shown to understand the region’s renewable source participation situation. The potential of offshore renewable resources is addressed by considering the published technical papers in scientific journals. The main conflicts and synergies associated with ocean space utilization are presented by considering the exclusive economic zone of each country. The status of the regulatory frameworks to promote and development of offshore renewable energies is presented. Two sections are dedicated to presenting the active, decommissioned and planned projects, research groups and laboratory infrastructures to develop the technologies. The last section discusses the future perspectives on the development of this sector in SA. It is observed that SA, with more than 25,000 km of coastline, has a great potential for offshore renewable energy; however, so far, these resources have not been explored commercially. Larger investment in the sector, establishing an adequate legal framework and deploying full-scale demonstration projects at sea are necessary for the commercialization of such technologies in SA.

"A Capabilities-Led Approach to Assessing Technological Solutions for a Rural Community." Energies 14, no. 5 (March 4, 2021): 1398. http://dx.doi.org/10.3390/en14051398.
Full textAbstract:
To improve access to affordable, reliable and sustainable energy in rural areas of the global south, off-grid systems using renewable generation and energy storage are often proposed. However, solution design is often technology-driven, with insufficient consideration of social and cultural contexts. This leads to a risk of unintended consequences and inappropriate systems that do not meet local needs. To address this problem, this paper describes the application of a capabilities-led approach to understanding a community’s multi-dimensional energy poverty and assessing their needs as they see them, in order to better design suitable technological interventions. Data were collected in Tlamacazapa, Mexico, through site visits and focus groups with men and women. These revealed the ways in which constrained energy services undermined essential capabilities, including relating to health, safety, relationships and earning a living, and highlighted the specific ways in which improved energy services, such as lighting, cooking and mechanical power could improve capabilities in the specific context of Tlamacazapa. Based on these findings, we propose some potential technological interventions to address these needs. The case study offers an illustration of an assessment method that could be deployed in a variety of contexts to inform the design of appropriate technological interventions.

Full textAbstract:
The transition towards more sustainable energy management can be supported by the diffusion of energy communities, i.e., coalitions of prosumers that are willing to exchange the energy produced locally. The optimization of energy management requires the solution of a prosumer problem that can become impractical when the number of users increases. This paper presents a parallel approach, based on an edge computing architecture, which is suitable for large communities. The users are partitioned into groups whose proportions, in terms of producers and consumers, mirror the composition of the whole community. The prosumer problems for the different groups are first solved separately and in parallel by local edge nodes. Then, the solutions are combined by a central entity to redistribute the energy among the groups and minimize the exchange of energy with the external grid. A set of experiments show that the parallel approach, when compared with an approach that solves the optimization problem in a single stage, leads to a notable reduction of computing resources, and becomes feasible in large communities for which the single-stage approach is impossible. Moreover, the achieved solution is close to the optimal solution in terms of energy costs.

Full textAbstract:
Integrated community energy systems (ICESs) are a good representative of local energy systems by integrating local distributed energy resources and local communities. It is proposed that costs should be allocated in a socially acceptable manner since there is no regulation in ICESs. In this paper, social acceptance is conceptualized from the dimension of community acceptance considering procedural and distributive justice. A fair process increases the understanding and the acceptance of the cost allocation outcomes, and a fair outcome leads to the acceptance of the cost allocation procedure. This approach adopted the multi-criteria decision-making technique to evaluate social acceptance to select a cost allocation method that was socially acceptable to local community members. The results show that our approach is unique and useful when multiple decision-making groups have to decide together upon the cost allocation method. It is able to provide quantitative results and optimal decisions from a multi-group decision-making perspective. The methodology developed in this research can be applied to any local community energy system to select a cost allocation method. Furthermore, the obtained results can be used by decision-makers to support them in the decision-making process. Based on our approach, policy implications are also analyzed to support the success of cost allocation in ICESs.

Full textAbstract:
Alpine biodiversity is subject to a range of increasing threats, but the scarcity of data for many taxa means that it is difficult to assess the level and likely future impact of a given threat. Expert opinion can be a useful tool to address knowledge gaps in the absence of adequate data. Experts with experience in Alpine ecology were approached to rank threat levels for 69 Alpine bird species over the next 50 years for the whole European Alps in relation to ten categories: land abandonment, climate change, renewable energy, fire, forestry practices, grazing practices, hunting, leisure, mining and urbanization. There was a high degree of concordance in ranking of perceived threats among experts for most threat categories. The major overall perceived threats to Alpine birds identified through expert knowledge were land abandonment, urbanization, leisure and forestry, although other perceived threats were ranked highly for particular species groups (renewable energy and hunting for raptors, hunting for gamebirds). For groups of species defined according to their breeding habitat, open habitat species and treeline species were perceived as the most threatened. A spatial risk assessment tool based on summed scores for the whole community showed threat levels were highest for bird communities of the northern and western Alps. Development of the approaches given in this paper, including addressing biases in the selection of experts and adopting a more detailed ranking procedure, could prove useful in the future in identifying future threats, and in carrying out risk assessments based on levels of threat to the whole bird community.

Full textAbstract:
The European Union sets targets for the extensive use of renewable energy. Meanwhile, the energy production network is changing and transferring from the classic “producer to consumer” scheme to new operation models, where a small consumer with local renewable energy systems becomes a producer–prosumer, an active energy consumer who is also an energy producer. This study evaluated a potential of Latvian households’ participation in the energy market as prosumers. The analysis was based on an informal prospective extrapolation data evaluation method, based on real historical data from the Central Statistical Bureau of Latvia, annual reports of distribution and transmission system operators, assessments, and the conclusions of relevant experts. In addition, the real performance of a photovoltaic (PV) system was evaluated to get information on the whole year’s energy balance, and to compare it with seasonal electricity price fluctuation. The Latvian electricity transmission system is able to accept about 800 MW of additional new renewable energy source (RES) capacity, so there is a great potential for prosumers. The biggest obstacle for a household’s involvement in the energy market is the lack of support mechanisms and relatively high cost of RES technologies. The results show that with the current dynamics of new microgenerator connections, Latvia will achieve the set goals regarding the involvement of prosumers in the achievement of RES goals only in the next century. In order to attract the public to energy production, the concept of energy community needs to be defined in Latvian legislation, a balanced peer trading mechanism needs to be developed for various RES self-consumption groups willing to sell surplus electricity, and tax policy conditions need to be reviewed for electricity transactions outside the NET (payment system), in order to fully ensure the rights of prosumers.

Journal of Energy in Southern Africa 27, no. 4 (December 21, 2016): 77. http://dx.doi.org/10.17159/2413-3051/2016/v27i4a1638.
Full textAbstract:
The Southern African Development Community (SADC) region has low energy security, exacerbated by electricity power cuts and load-shedding in almost all its member states. Green energy has the potential to contribute to the shortfall in the supply of energy required on the grid network during daily (morning and evening) and seasonal (winter) peak periods. The Statistica 12 program was used to analyse and compare responses between identified groups in the SADC region’s Energy sector. Multivariate analysis of variance and analysis of variance were used to examine associations between variables within the identified categories of respondents, and conclusions were made about six hypotheses. The categories of respondents sampled included: people associated with fossil fuel and renewable energy; people with experience of 1-6 years and more than 6 years; researchers and industry practitioners; practitioners based in South Africa and in other SADC countries; and a category based on practitioners’ positions (junior managers, middle managers, and senior managers) in their respective organisations. The study found that energy practitioners generally support a transition to green energy sources and there is consensus that the uptake of green energy will be slow initially, driven by low costs of fossil-based sources, but the uptake will eventually grow exponentially to a point of driving industries in future. The study recommends that SADC countries prioritise mapping of green energy resources to facilitate the selection of suitable green energy options in order to meet local energy needs and environmental protection. Research and development of suitable green energy storage technologies to overcome intermittency of some green energy sources must be expedited in the region.

This paper studies the general SoC design AMBA bus and proposes an automatic generation method of software structure test data based on adaptive data optimization algorithm. By simplifying the basic particle expansion equation and eliminating the particle velocity term, an adaptive scheme based on inertia weight is proposed. In the research process, this article fully considers heterogeneous groups. Investment companies are divided into three types of decision-makers: reciprocal, intelligent, and leveraged, and their investment behavior is modeled. Given that factors such as technical level will affect the future of the project, and swarm simulation software is used to simulate and analyze the impact of the profitability of smart community microgrid construction projects on decision-making and to conduct dynamic research on market modeling risks. This article first outlines the construction of the renewable energy macro- and micro-market risk decision-making behavior model and clarifies the logic process of the market to promote the consumption of renewable energy. Then, it analyzes the causes of market risks based on dynamic models, first examines the relationship between key risks and risk factors, forms risks that affect returns (bilateral random risks and market efficiency risks), and then an analysis framework for the impact of renewable energy. This paper applies it to the analysis of data-based algorithms, thereby promoting the development of data-based algorithms.

Full textAbstract:
Wastewater is considered a renewable resource water and energy. An advantage of decentralized sanitation systems is the separation of the blackwater (BW) stream, contaminated with human pathogens, from the remaining household water. However, the composition and functions of the microbial community in BW are not known. In this study, we used shotgun metagenomics to assess the dynamics of microbial community structure and function throughout a new BW anaerobic digestion system installed at The Netherlands Institute of Ecology. Samples from the influent (BW), primary effluent (anaerobic digested BW), sludge and final effluent of the pilot upflow anaerobic sludge blanket (UASB) reactor and microalgae pilot tubular photobioreactor (PBR) were analyzed. Our results showed a decrease in microbial richness and diversity followed by a decrease in functional complexity and co-occurrence along the different modules of the bioreactor. The microbial diversity and function decrease were reflected both changes in substrate composition and wash conditions. Our wastewater treatment system also decreased microbial functions related to pathogenesis. In summary, the new sanitation system studied here fosters microbial groups and functions that allow the system to efficiently and robustly recover carbon and nutrients while reducing pathogenic groups, ultimately generating a final effluent safe for discharge and reuse.

Full textAbstract:
To better understand social sustainability in the context of rapid boom growth and decline, we examine longitudinal social change in the modern boomtown of Colstrip, MT. Using a mixed-methods approach that includes two waves of a community survey—administered in 1996 and 2018, respectively—and focus groups conducted in 2018–2019, we explore shifts in residents’ sense of community as well as their perceptions and attitudes about current challenges to their community’s future and sustainability. We show that, despite surviving previous boom and bust periods related to changes in the coal industry, this community now faces a new reality that involves the closure of all local power plants. However, both survey responses and residents’ narratives indicate a strong sense of community and support for developing strategies that address challenges to the town’s future. This exploratory case study helps to extend the literature by contributing to a greater understanding of the experiences of contemporary workers who individually migrated to a small, rural energy town but who now, as a community, face an uncertain future, and by illuminating the role of sense of community in both social and environmental sustainability efforts.

Full textAbstract:
In the development of new and renewable energy (EBT), biomass is one alternative energy source that will be developed. Apart from the industrial plantation program (HTI), the development of energy forestry has the opportunity to be developed through forest farmer groups and other schemes, such cooperative. Energy forestry can be defined as a forest producing biomass for energy. At present, the forest land managed by the community in the form of HKm (community forest) has reached 244,434.67 ha in 2018, and will continue to increase in the following years. Energy forestry development on HKm land in West Lombok’s Forest Stakeholder Unit (KPH) is a supposition, which is an effort to extent the development of energy forestry. Interpretative Structural Model identifies problems in developing energy forestry in HKm land. Energy forestry on HKm land in West Lombok’s KPH can basically be developed by reducing obstacles encountered. These obstacles include the strict SKAU, lengthy to harvest, uneasy marketing, agricultural land competition, disrupted daily needs, and lack knowledge of conservation. The results of ISM processing show that the obstacles needed firstly to be addressed are strict SKAU and Lack knowledge of conservation, which are followed by agriculture land competition, subsequently disrupted daily needs, uneasy marketing, and lengthy to harvest. In order to conquer the initial obstacles, there is a need to facilitate issuing SKAU without reducing supervision for security. At the same time, it is important to transfer knowledge of conservation with a pilot project.

Full textAbstract:
Small-scale community fishers dominate fisheries in Cambodia. In the central floodplain of Cambodia, 35% of rural dwellers are part-time fishers and 15% full-time fishers. By 2012, the Cambodian government had abolished all commercial fishing lots and put these resources under the management of community fisheries. One challenge in the implementation of community-fisheries management is budget shortages and resultant livelihood stress. To address this problem, savings groups were established. The Sustainable Communities International program provided establishment and facilitation support for savings groups in 10 community fisheries in the Kampong Chhnang Province. The savings groups were recognized as useful support facilities, meeting the needs of community fishers and sustainable community fisheries operations. However, there were concerns about the sustainability of the savings groups and the fisheries. To date, there are no documented case studies of savings groups for community fisheries. This study was conducted in two community fisheries in the Kampong Chhnang Province. We found that the internal rules of the savings group must reflect the opinions and perceptions of the members to ensure sustainable operation. Education and integrated livelihood activities were important considerations in encouraging participation. These insights are also useful for community fisheries elsewhere.

The concept of ‘building back better’ is being mainstreamed in international development to minimize future devastation from natural disasters. This paper reports on presentations and discussions from the Second International Symposium on Recovery after Mega Disasters: People, Community and Planning, held March 16, 2015 during the Third World Conference on Disaster Risk Reduction. International experts, including practitioners and researchers, presented varied recovery efforts and insights. The three following principles emerged from the symposium. 1) Relocation, compact (re)development, renewable energy, and flood controls are key policy focuses in recovery plans, and require careful individual and community involvement, planning designs, and information sharing. 2) Identifying unique local resources is key for successful recovery and can help formulate innovative strategies. 3) As rebuilding that considers local culture, systems, and groups aids in resilient recovery, planning practitioners need in-depth understanding of local contexts to derive better solutions. Given these three principles, participants agreed that at its core, the concept of ‘building back better’ requires tailor-made planning designs and processes.

Full textAbstract:
Coastal and terrestrial fisheries communities in Europe, often economically marginalised, are likely to face severe impacts as climate change becomes more acute. Although progress on climate mitigation and adaptation from national governments remains slow, local development actions can also address these impacts from the bottom up. In this paper we analyse the Fisheries and Sea Operational Programme 2014–2020 and 36 Local Development Strategies prepared within the framework of this programme for the case of Poland. The strategies, which were prepared by cross-sectoral, area-based partnerships known as Fisheries Local Action Groups, are analysed using a content analysis approach. The aim was to assess the degree to which local stakeholders sought to address the climate challenge. We found that the mitigation of climate impacts and the development of renewable energy did not feature prominently in the analysed documents, suggesting that both central policymakers and local stakeholders in Polish fisheries regions had a low level of awareness about the climate problem and their potentially important role in addressing it. Transformation to a post-carbon society undoubtedly requires additional, targeted support and extensive educational activities at the local level, in Poland and elsewhere.

Full textAbstract:
This article details the successful campaign to decommission two hydroelectric plants and a dam on Fossil Creek in Arizona—a rare perennial stream in the Southwest. Beginning in 1991, American Rivers, the Sierra Club, and community service groups utilized the Federal Energy Regulatory Commission’s recommissioning process to force the removal of the dam and plants. They faced opposition from the plants’ owner, the historical community, and citizens concerned over the loss of a seemingly “green” source of renewable energy. This study argues that Fossil Creek was a pioneering achievement in the larger movement to remove dams in the United States. After Edwards Dam in Maine, it was only the second dam taken down to restore fish species. In Maine—and in later dam removals in Washington and Oregon—valuable salmon and other anadromous species were the focus of conservation efforts; but in Fossil Creek, the effort was unique in that it centered on helping to save several species of rare desert fishes that had little or no sport or commercial value. The Fossil Creek victory represents an important example of the complex intersection of ecological restoration and environmental politics in the late twentieth century.

Full textAbstract:
This paper aims to analyze the implications of Feed-In-Tariff (FIT) support removal in the UK’s community energy sector and make recommendations for future business practices. European countries, including the UK, have recognized the critical role of Community Energy Cooperatives (CECs) in achieving low-carbon-energy transition targets through citizen engagements. However, due to the withdrawal of FIT support and other incentives in the UK, CECs struggle to sustain their profitability and growth. The subsidy-free, market-oriented policies have necessitated that CECs explore new business opportunities in collaboration with other actors of the business ecosystems. In this paper, we reviewed the impact of FIT support removal on community groups in the UK's member states, England, Scotland, and Wales. We analyzed effective business practices that CECs could follow to improve business viability and achieve growth. Based on our review, we make three recommendations for the business practices that can help CECs to remain profitable and grow in the UK’s subsidy-free environment. We recommend that CECs 1) take part in shared ownership projects, 2) collaborate with local actors for bottom-up initiatives, and 3) explore low-interest financing models within the business ecosystem. The implication of findings from this paper includes new knowledge for CEC managers and policymakers in countries where the community energy sector is at a novice stage.

The main components of development are energy. The manufacturing of biogas is an established technology that is largely used to produce sustainable energy as well as to monetize organic waste. The potentiality of the development of biogas energy is very high in rural Nepalese community and the mainly used for cooking. This article aims to know the impact of biogas plant installation on the community people in their lifestyle including the study area of Lekbesi Municipality - 4 Dasharathpur, Surkhet. Quantitative research design was adopted to meet the objectives and extent of activity as well as the descriptive. Data were collecting through the questionnaire method. The purposive sampling of 72 HHs was taken to gathering the necessary information. The study found that, Biogas plant is a reliable source of renewable energy for limiting deforestation rates, increasing productivity, and protecting the environment from human population increase. The workloads of people, particularly women, have decreased in everyday activities since the installation of the biogas plant, which has had a good impact on the family members’ workload schedules. The current study shows that there is a rising tendency toward reliance on biogas plants, which appears to be solid evidence for the preservation of forest resources. The findings of this article have been helpful for government, non-government, as well as social groups to develop better plans, policies, and practical tactics for providing biogas energy to the poorer sector of rural residents.

Full textAbstract:
Increasing reliance on deep-water renewable energy has increased concerns about the effects of the electromagnetic fields (EMFs) generated by submarine power cables on aquatic organisms. Off southern California, we conducted surveys of marine organisms living around energized and unenergized submarine power cables and nearby sea floor during 2012–2014 at depths between 76 and 213 m. In general, EMFs declined to background levels about one meter from the cable. We found no statistical difference in species composition between the fish assemblages along the energized and unenergized cables. The natural habitat community statistically differed from both energized and unenergized cable communities. Within species (or species groups), we found no differences in densities between energized and unenergized cables. Total fish densities were significantly higher around the cables than over the natural habitat. We found that invertebrate communities were structured by habitat type and depth and, similar to the fishes, there was no statistical difference between the energized and unenergized cables. Individually, the densities of four invertebrate species or species groups (Metridium farcimen, Luidia spp., unidentified black Crinoidea, and Urticina spp.) differed between energized and unenergized cables, but this difference was not significant across all depth strata. The invertebrate community inhabiting the natural habitat strongly differed from the energized and unenergized cable community exhibiting the fewest species and individuals.

Full textAbstract:
Contemporary tourism favors niche offers and heritage tourism is successful niche tourism. The cultural mapping of Făgăraș Land (Romania), accomplished during a project conducted by Transilvania University of Brașov, highlights the groups of caroling lads as a main local resource of intangible cultural heritage. The field research indicates that during winter, celebrations of the life of rural communities are organized around the group of lads. Currently, the group only performs a ritual role, but in the past the group had community work attributes, which could be resumed. Additionally, a sustainable heritage tourism can be developed around the groups of lads from Făgăraș Land. That is a form of niche tourism based on the aforementioned concept of foster Christmas relatives. The concept was outlined during the field research carried out as part of the project and refers to host families providing tourists access to the performance of group of lads within the community during the winter celebrations. Resuming the old attributes of the group of lads along with niche tourism could contribute to the sustainable development of rural communities and building local cultural identity. Additionally, they would also consolidate the status held by group members within the community.

Full textAbstract:
Morocco is one of the countries investing more and more in Renewable Energy (RE) technologies to meet the growing demand for energy and ensure the security of supply in this sector. The number of solar projects planned and implemented, as well as solar thermal projects in the form of Concentrating Solar Power (CSP) installations is steadily increasing. Many of these installations are designed as large utility systems. In order to provide strong evidence on local, regional and even national impacts, this article examines the impacts of large-scale renewable energy projects on territorial development, based on a case study of the NOOR 1 (Concentrated Solar Power (CSP)) project in Ouarzazate, Morocco. The data collected during this study, conducted through semi-structured interviews with experts, stakeholders, local community representatives and combined with an analysis of documents provided by the NOOR 1 project managers, investors and consulting firms specialized in the field of Renewable Energy, provide detailed evidence on the type and magnitude of impacts on the economic development of the Moroccan southern region where the NOOR 1 plant is located. The data collected is analyzed using NVIVO software. The study results in a consolidated list of many impacts with varying levels of significance for different stakeholder groups, including farmers, youth, women, community representatives and small and medium firms owners. It should be noted that the importance of analyzing the economic impact of large infrastructure projects is widely recognized, but so far, there is little published in the academic and professional literature on the potential impacts of these projects at the local level. Even less information is available on the local impacts of large-scale project implementation in Morocco. While many macroeconomic studies have fed the recent surge in investment in RE projects with the promise of multiple social, economic, environmental, and even geopolitical benefits at the macro level, public debates and discussions have raised considerable doubts. The question of whether these promises would also leave their marks at the local level has also arisen. Despite these uncertainties, very few academics and practitioners have conducted research to empirically develop a good understanding of the impact of RE projects at the local level. To fill this research gap, the economic impact analysis of NOOR 1 provides a detailed empirical overview, which allows a better understanding of the effects that the infrastructure developments of Concentrated Solar Power (CSP) plants can have on the economic environment in which they are located.

One of the ways to reduce oil consumption and land use is to use cashew nut processing waste to produce biocharcoal briquettes, which are made from cashew nut shells. The business potential of cashew nuts (Anacardium occidentale) in Ngaglik Hamlet, Ngeposari Village, Semanu District has prospects as a cashew nut producing area in Gunung Kidul Regency. Cashew nut shells contain fuel with high calorific value and long burning time and are safe for health. However, cashew shell waste has not been managed optimally. The purpose of this service program is to manage cashew nut shell waste as an alternative solid fuel product that can be used by the community as renewable energy. Lecture and discussion methods as well as question and answer are used for training. The contribution of this activity to society through technology transfer produces biobriquettes as a renewable and environmentally friendly energy. The application of science and technology biobriquettes from cashew nut shells has been adopted by cooperator farmers. This is shown by the results of the evaluation that 100% of the farmers made biobriquettes using the tools available in farmer groups for their own needs or for sale. The success of the application of science and technology was due to the transfer of technology from universities and the participation of cooperative and non-cooperative farmers from Ngaglik Hamlet, Ngeposari Village, Semanu District, Gunungkidul Regency, which went well.

Full textAbstract:
To examine how cross-strata neighboring behavior in a mixed-income community can influence the consumption choices of individuals in low-income groups, and to improve the prediction accuracy of the consumption choice model of low-income groups for small sample sizes, we developed a support vector machine (SVM) algorithm based on the influence of neighboring behavior. We substituted the predicted latent variables into the SVM classifier and constructed an SVM prediction model with latent variables based on reference group theory. We established the model parameters using cross-validation and used low-income residents from a mixed-income community in Shanghai as study objects to empirically test the model’s performance. The results show that the SVM selection model with latent variables has good prediction accuracy. The proposed model’s accuracy was improved by 1.29% on the basis of the particle swarm optimization (PSO)-SVM model without latent variables, and by 19.35% on the basis of the SVM model with latent variables. The proposed model can be employed to predict the consumption choices of individuals in low-income groups. This paper offers a theoretical reference for investigating neighboring behavior in a mixed-income community and the consumption choices of individuals in low-income groups and is practically important for urban community planning systems.

This research aimed to reveal the response characteristics of soil microbial community structure to different degrees of tourism disturbance. To explore the soil microbial community structure’s response mechanism, we set up continuous plots with different interference intensities: high disturbance, middle disturbance, and the control area. We collected 0–10 cm topsoil in all plots and used Illumina MiSeq high-throughput sequencing method to obtain and analyze the response characteristics of soil microbial community composition and structure under different tourism disturbances. These results were then combined with alpha diversity and environmental factors to explore the microbial response mechanism. In the tested soil, Acidobacteria, Chlorocurve, and Proteobacteria were the main bacterial phyla, while Basidiomycota and Ascomycota were the main fungal phyla. Based on the phylum, the relative abundance of the microbial community between the interference groups was compared using a significance test, with significant differences found between the interference groups in the phyla Chloroflexus, GAL15, Rokubacteria, and Blastomonas (p < 0.05). The relative abundance of the dominant phyla in the fungal community was significantly different among the groups (p < 0.05). A principal component analysis of the soil microbial community structure suggested that the soil microbial community structure was significantly different for different interference levels.

Full textAbstract:
The ethnodevelopment emphasizes cultural dimension as identity form, the encouragement of local and marginalized groups in decision-making, and the crucial role of the indigenous knowledge and skill to sustain local livelihood. In contrast, females in rural areas have the same potential as men. It is then necessary to empower females with many ethnic backgrounds as farmers. The Women Farmers Group is a forum consisting of women engaged in agricultural activities within various ethnic groups. In addition, females expect to play a role in economic empowerment to achieve financial independence and build their territory. This research uses a qualitative perspective to illustrate Community Based Agritourism, which dominated ethnic lives in two rural areas of the Pesawaran Regency, and the female characteristics among farmers groups to promote the territory by linking social capital from many stakeholders. Agritourism initiates the diversification of agriculture products and supports the revitalization of rural areas. It is also an important instrument to improve the social status of the female. Both local and national levels in agritourism development need to promote female contributions. The assistance of Women in economic empowerment requires solid institutional support. Furthermore, it emphasizes state institutions as the key players in agritourism development.

This study analyses the Active Citizens program conducted in seven Czech elementary schools in 2017/2018. The data were obtained in a mixed-design research study containing pre/post experimental/control groups (N = 114), eight focus groups with selected students (N = 56), and group interviews with teachers (N = 14). The mean age of the students was 13.8 years. The study focuses on the students’ and the teachers’ perception of the process, the program’s barriers and benefits, and on the impact of the program on the students’ self-efficacy and on perceived democratic school culture. The analysis revealed that while the participants felt empowered because of their experience, they started to perceive their school environment as less democratic than before the program. The program also likely influenced girls more than boys as the latter seem to have been unaffected. Finally, the implications of the findings for the practice are discussed.

Although biogas technology is not something new in Indonesia, the obstacles faced by farmers are their lack of knowledge about processing cow dung into biogas and making of biogas reactors. Community service has been undertaken to provide knowledge through guidance and counseling methods to farmers about biogas, biogas reactor manufacturing and technology, and the advantages of biogas reactors, both in terms of economic and environmental values. Stages of the implementation of the activities; 1). Provide guidance and counseling to farmers about biogas and how to manufacture biogas reactor, 2). Provide guidance and counseling about the safety of biogas reactors, 3). Conduct periodic monitoring of farmer groups that are partners to the continuity and continuity of activities. The result of the activity is the availability of biogas reactor in farmer group in Pauh sub-district. The fermentation process to produce biogas in the reactor is approximately 3 weeks. Biogas reactors are built easy to make and cheap.

Full textAbstract:
The sustainable development of micro-hydropower (MHP) plants is a challenge for rural electrification in developing countries, especially in Indonesia, which has diverse ethnic groups, cultures, and traditions in several isolated locations due to its complex terrain. The uniqueness of a social situation in a location can affect the sustainable electrification development. This study aimed to assess the sustainable development of MHP plants in the Kasepuhan Ciptagelar, which has unique traditions and cultural characteristics. The assessment was conducted using the sustainable development indicator (SDI) method, the Ilskog method, which can include social, economic, environmental, technical, and institutional dimensions. Data were collected through field investigations and qualitative dialogs to understand the culture and ways of thinking. The results of the Ilskog method analysis revealed that the environmental dimensions had the highest scores, whereas economic dimensions had the lowest scores, indicating that the cultural background of the Kasepuhan Ciptagelar impacted the SDI scores. This was attributable to the decision of Kasepuhan’s traditional leader, which strengthened the community commitment to renewable energy use. However, the cultural background adversely impacted monetary income to sustain MHP plants. This study proposed that community innovation and microcredit availability could improve productive activities, resulting in better economic conditions to sustain MHP plants.

Full textAbstract:
The objective of this study is to evaluate the contributions of ecosystem-based adaptation (EbA) practices to the water–energy–food (WEF) nexus balance, design practical pathways, and analyze barriers towards achievement of EbA-WEF balance. An area case study and descriptive methods were used to analyze data collected from 50 community forests (CFs) spread across three regions in The Gambia. Extensive information from relevant literature sources was also referred to in this study. Fourteen priority EbA practices were established and categorized into four major groups based on their application similarities. Among the anticipated ecosystem services were enhanced water resource conservation, food and feed production, enhanced energy supply, and improved community livelihoods to enhance their resilience. Pathways on how each practice under the broad category contributes to water, energy, and food were developed to demonstrate how they individually and collectively contribute towards the nexus balance. Key enablers identified included a conducive policy framework, institutional support, diverse incentives, information, knowledge, and technology transfer, and climate and non-climate barriers were cited as impediments. The paper concludes by outlining recommendations to overcome the established barriers.

Full textAbstract:
Urbanisation brings with it increased pressure on land and land uses, particularly green spaces. There has been considerable interest in community food growing in green spaces as part of a wide trend for gardening in the UK, which has been found to bring social, health, and well-being benefits. Such activity tends to take place in community-managed gardens and allotments. In light of the context of austerity within which local authority parks departments currently operate, this study tested the acceptability and feasibility of parks as a potential urban setting for Community Food Growing (CFG) in Sheffield, UK. Employing a combination of resident questionnaires and interviews with community groups and professionals, the study results showed localised differences in the acceptability and feasibility of CFG. Residents’ propensity to want to get involved in CFG differed by age and household composition, which, if acted on across the city, could significantly change the demographic make-up of parks-based community groups in the city. Barriers to CFG in parks were described by community groups and park managers as security and vandalism, need for resources, and undue pressure on the local authority as land-owner. We discuss the emergent questions around who is best placed to manage urban parks, particularly when the public sector is subject to stringent austerity budget measures. The paper concludes with commentary and recommendations about the importance of governance arrangements if CFG is to be included as part of the activities supported and managed in urban parks.

"Environmental impacts on marine energy: collision risks for marine animals and priority species for monitoring in Brazil." Revista de Gestão Costeira Integrada 22, no. 2 (June 2022): 127–43. http://dx.doi.org/10.5894/rgci-n496.
Full textAbstract:
ABSTRACT Brazil has great potential for the development of technologies for the conversion of marine energy from waves and tides, which raises the discussion about the possible environmental impacts of these projects. This article seeks to synthesize knowledge about the risks of collision of marine animals, such as mammals, fish and birds, with marine renewable energy (MRE) devices, as well as to identify priority species for environmental monitoring along the Brazilian coast. The risk of marine mammals colliding with MRE devices is influenced by regional and behavioral factors. The risk of collision in a fish community is influenced by the avoidance behavior, the distribution of fish in the MRE sites and the stages of the enterprise (installation, operation and maintenance). Seabird collision risk is influenced by species behavior (geographical distribution, seasonal habitat use, diving time and depth) and the location of MRE structures (surface and/or water column). The survey of priority species for monitoring the risk of collision with MRE devices in Brazil consisted of 5 species of marine mammals, 13 taxa of seabirds, 5 species of endangered sea turtles and 18 species or groups of species of fish of economic importance to the country. The research review did not record the occurrence of collisions with marine animals. However, this does not mean that they did not occur, but that they may not have been observed due to monitoring challenges. The study concluded that research on the interaction of marine animals with MRE devices should be encouraged, even in prototypes and non-commercial projects, in order to reduce knowledge gaps and support the development of MRE in an environmentally sound manner. Keywords: Marine renewable energy, Collision risk, Species, Marine animals.

Full textAbstract:
As on many other European islands, the energy system of Mayotte suffers from low reliability of supply, low share of renewable energies, and high costs of supply. Residential Demand Response (DR) schemes can significantly increase the flexibility of the inherent weak power grid, increasing the potential for renewable energy integration. Given that active involvement of the population is required to unlock the potential of DR, pre-assessing the population’s preferences in DR is vital to tailor favorable schemes and assure long-term uptake of the solution. As a fundamental study, this paper assesses the population’s preferences on direct load control (DLC), electricity tariffs, major motivation, and remuneration goods by processing findings from a survey of 146 residents on Mayotte. Advanced k-means cluster analysis, multinomial logistic regression, one-way analysis of variance, and Chi-square tests were applied to the survey responses to identify socio-demographic influencers. The results indicate four distinct groups of people concerning their interest in DR schemes, with increasing age being a significant predictor for higher interest. Interest in DLC varies with the device/appliance controlled and socio-demographic characteristics. The preferred tariffs correspond to the results of previous literature. Financial incentives play a subordinate role in the main motivation for participation compared to social and environmental attractions as well as non-monetary remuneration goods, supporting the impression of a high sense of community and suitability of islands as laboratories for energy innovations. Follow-up studies must reflect on the ability/willingness to pay as well as the current state of awareness and knowledge of electricity supply to validate speculations on underlying reasons for DR preferences and flag constraints for the DR scheme implementation.

Full textAbstract:
The aim of this work is to identify community the initiatives anchored to community-based tourism (CBT) in Ecuador with the aim of providing an overview of the current reality of community tourism in the country, in addition to publicizing the product lines under development within community initiatives. The methodology used is a descriptive analysis based on the review of secondary sources, which reflect the reality of the different tourism initiatives related to the Plurinational Federation of Community Tourism of Ecuador (FEPTCE) at the level of continental Ecuador. FEPTCE groups indigenous, Afro–Ecuadorian, Montubian and mestizo communities, who depend on their territory and have identified tourism as a mechanism to continue living with dignity within these territories, due to the option of economic diversification that is generated. Within the communities that belong to the FEPTCE, living with dignity implies achieving a good quality of life, which is not based on satisfying a series of basic needs, but implies going further, achieving the idea of “Good Living”, that is to say, reaching an appreciation of well-being, based on the conception of the full set of what culture is, in order to generate comprehensive sustainability of its spaces. Among the main results, the distribution and coverage that the FEPTCE has within continental Ecuador regarding community tourism is shown and analyzed. As a formal network of community-based tourism, it is made up of five networks at the regional level and nine at the provincial or cantonal level, which are analyzed in this study. The consolidation of the initiatives launched has been difficult with only 83 of the initial 121 being active and only 18 registered as community tourist centers. This case study shows that in Ecuador the network approach as the first step in the development of the CBT worked. Therefore, the development of the CBT must be approached from a network approach in which indigenous peoples (indigenous, mestizo, Afro-descendant, etc.) participate, administrations, the private sector, civil society, NGOs and tourist destinations, to which they must to join academic institutions by contributing solid data obtained through research that helps tourism development.
