Basic sciences, technology and human sciences in aeronautics are integrated in favor of renewable energies for sustainable development.Thus, the objective of this project is to create a rainwater and condensed water storage system with automated irrigation, powered by solar energy that provides crop moisture and contributes to the reduction of CO2 in the semi-desert region of Querétaro. The methodology used is action research, which consists of observing and detecting a real problem to immediately analyze and assess the possibilities of intervention. In this case it was the waste of natural resources in the university (water and solar energy). An action strategy was designed afterwards which consisted in: 1. Integration of a team of specialist teachers and students. 2. General planning of the project. 3. Theoretical and field research. 4. Systems design: hydraulic, structures, automated irrigation with solar energy. 5.Application of device tests and the study of the process of crop growing and composting. Our contribution in this project is above all social and ecological and not to science; university social responsibility is encouraged emphasizing the importance that the application of technology offer alternatives for the care and use of natural resources and greater use of renewable energy. As an added value, the project contributes to applied research with an interdisciplinary approach of professors and students of different aeronautical careers in favor of sustainable development. It is clarified that during this initial stage there is still no scientific contribution made as we plan ,in a subsequent stage, to test and show levels of radiation and humidity in the region.

The potential of abundant natural resources in Gunungsari Village, Serang Regency, is still unable to improve the economic standard of life of the community, this is due to the lack of community skills and the lack of public knowledge in optimizing the potential of these natural resources into economic added value. This method of community economic empowerment through optimization of natural resource potential in Gunungsari Village, Serang Regency uses an environmental communication strategy which includes 1) Material Stage; 2) Energy Phase; 3) Information Stage, and 4) Evaluation Stage. The results of community service concluded that community economic empowerment through optimizing the potential of natural resources received a positive response and enthusiasm from the community, with the success rate of training program indicators being on an interval scale with an average value of 70% or a fairly good category. Thus it can be concluded that encouraging the skills training of the Gunungsari Village community in utilizing the natural resource potential of the papaya fruit is very important to improve the welfare of rural communities.

The primary objective of this paper is to present opportunities for creating virtual 3D models of defunct historical buildings, reconstructed on the basis of archival and field research, and the effective promotion and visualisation of such models through a thematic web application. The secondary objective is to increase the tourism potential and attractiveness of the various historical sites and the studied region. The comprehensive methodical processing of documents and the creation of 3D models of objects and other digital visualisation requires not only high-quality programmers and graphic artists, but especially scientists who create historically-relevant descriptive texts, real schemes, and historically acceptable models that can be computer-processed, visualised, and used as an effective tool for the development of tourism. Research and follow-up activities require an interdisciplinary approach, i.e. the cooperation of experts from various disciplines. The research processed in this study points out that even simple, now widely available modern means of communication, such as websites, can be effectively used for the promotion and publicity of this type of attraction. High-quality 3D models and visualisations of buildings and specific destinations, or cultural and technical monuments, can thus become available to tourists also outside museums. This paper introduces the opportunities of digital presentation of preserved, partially defunct and, especially, completely defunct historical buildings and sites that are often almost unknown to tourists. In many cases, only their shells or foundations remain. In terms of cultural heritage conservation and monument protection, these sites are often among the most important religious buildings from various historical periods. This study focuses on the Middle Ages and locations in Slovakia (former Hungary), and presents a methodology that is generally applicable for the research and visualisation of any similar cultural sites, and thus opening up their potential to tourists.

This article explores governance and power relations within the guaraná (Paullinia cupana) global commodity chain (GCC) of the Sateré-Mawé, an Indigenous group of the Lower Amazon, Brazil. The paper draws on ethnographic work and joint field research in Pará, Brazil and pursues an interdisciplinary approach combining economic geography and anthropological interest in ontological diversity. It describes the guaraná value chain in commodity chain terms, and discusses issues of narrative, transformation, and power in the community of values associated with the chain. Guaraná is a ritual beverage of central importance to Indigenous cosmology and is now a commodity traded within the global Fair Trade network. We found that the commodity chain is the result of not only economically, but also politically motivated Indigenous and European actors. It has a simple organization and is based on inter-personal business relations, with neither retailers nor producers controlling the chain. In this context, diverse actors, including Indigenous and non-Indigenous agents, cooperate in a joint project despite their, at times, differing values. These values are discernable in the narratives and discourses braided around the chain. This paper identifies the values at work and the tensions and dissonances produced as they rub against each other. It argues that, far from making the chain unmanageable, the tensions are creative and help the chain’s participants to bridge between Brazil and Europe.

The article is devoted to the development of methodological approaches to the use of unique natural resources (characteristics) of territories that are capable of being embodied in the consumer properties of food products produced at enterprises located in these territories. The development and production of such goods creates real prerequisites for the formation of a reputation, both of enterprises themselves and of the territories (regions) where they are located. Based on the reputation formed due to the unique natural characteristics of the area, it is recommended to develop trademarks, create regional product brands with the aim of using them in promoting goods with unique consumer properties to other regional markets, including foreign ones. The conditions and rules of registration of the name of the place of production of goods, the reflection of the toponym in the brand name are described; an overview of regional Altai product brands is presented, including the unique natural properties of the area in their consumer properties. The provision that the most acceptable for the initial presentation of Altai in other regional markets is Altai honey. As the main form of promoting Altai honey to other regional markets, it is proposed to use value-added chains. It substantiates the provision that regional product brands promoted to other regional markets, including foreign ones, contribute to the formation and development of the image of the territory, in this case, the Altai Territory. The material presented in the article can be used in the development of specific methodological proposals for solving the problems of the development of territories and enterprises located on them.

Solar energy can be stored in subsurface and extracted to melt snow and deice in winter. In summer, the bridge deck heat element in a bridge deicing system could serve as a solar energy collector without additional cost. Numerical models were developed in this study to investigate the performance of a bridge deck solar collector. The effects of radiation intensity and wind speed on the solar energy collection efficiency of a bridge deck solar energy collector were discussed and analyzed. The results show that the temperature of the slab was decreased during the solar collection process, and the solar energy collection efficiency of the bridge deck solar collector was about 26~47%. The collection efficiency of solar energy at a given wind speed was increased with the decreasing of the radiation energy, and this effect was more pronounced when the wind speed was higher. The solar energy collection was beneficial to the durability of the top asphalt layer as well as the structural response of the bridge because the magnitude and gradient of the slab temperature were much lower when the bridge deck served as a solar energy collector.

O objetivo geral deste artigo é analisar a sustentabilidade ambiental do turismo na Bahia, sob a ótica do desenvolvimento local, tomando como referência o município de Itacaré que tem vivenciado nos anos 2000 uma “explosão” dessa atividade. Insere-se o aspecto ambiental em função de que o turismo desenvolvido no município está fortemente associado ao meio ambiente local. Parte-se assim dos intensos debates acerca das relações entre desenvolvimento e meio ambiente, propondo-se uma abordagem interdisciplinar baseada na problemática ambiental, especificamente a respeito das externalidades derivadas da atividade econômica exercida pelo homem sobre o meio natural, aqui tratada pela ótica da atividade turística. Em termos metodológicos, faz-se uso da pesquisa descritiva e metodológica, a partir da análise bibliográfica e de pesquisa de campo. Foram entrevistados e solicitados a responder ao questionário estruturado 30 empreendedores, diretores e gerentes das empresas que atuam no setor de hospedagem, no período de 13 a 21 de junho 2016, na localidade de Itacaré, Bahia. Esse destino turístico está inserido na Costa do Cacau, onde prevalece a prática do Ecoturismo. Este se diferencia, dos demais segmentos do turismo, por se apoiar em valores que reforçam o compromisso com a preservação ambiental e a interação com a comunidade local. Para tanto, a pesquisa privilegia dois recortes metodológicos: um recorte quantitativo, denominado Quociente Locacional (QL) e, um recorte analítico, utilizado para a caracterização de aglomerações produtivas em regiões de baixo e médio desenvolvimento, denominado Arranjo Produtivo Local (APL). Diante das análises realizadas, concluiu-se que a localidade estudada pode ser identificada como APL de turismo em fase de consolidação. Na dimensão ambiental constatou-se a necessidade de implementação de ações, públicas e privadas, que direcionem e potencializem medidas que elevem a atividade turística de forma sustentável. Especificamente, relacionadas a redução do consumo de água e energia, aproveitamento da água da chuva, gerenciamento de resíduos sólidos e implementação de coleta seletiva. Espera-se como resultado deste trabalho, subsidiar o desenvolvimento de políticas públicas direcionadas ao desenvolvimento sustentável do turismo. Ecotourism and Local Productive Arrangement: an analysis of environmental sustainability in Itacaré (BA, Brazil) ABSTRACT The general objective of this article is to analyze the environmental sustainability of tourism in Bahia under the perspective of local development, taking as reference the municipality of Itacaré, which has experienced in the year 2000 an "explosion" of this activity. The environmental aspect is inserted because tourism developed in the municipality is strongly associated with the local environment. It is based on the intense debates about the relationship between development and the environment, proposing an interdisciplinary approach based on the environmental issue, specifically on the externalities derived from economic activity carried out by the man on the natural environment, here treated by the view of tourist activity. In methodological terms, descriptive and methodological research is used, from bibliographic analysis and field research. Thirty entrepreneurs, directors and managers of companies operating in the lodging sector were interviewed and asked to respond to the structured questionnaire, from June 13 to 21, 2016, in the city of Itacaré, Bahia. This tourist destination is inserted in the Cacao Coast where the practice of Ecotourism prevails. This is different from other tourism segments, because it relies on values that reinforce the commitment to environmental preservation and interaction with the local community. For this, the research privileges two methodological cuts: a quantitative cut, called Locational Quotient (QL) and, an analytical cut, used for the characterization of productive agglomerations in low and medium development regions, denominated Local Productive Arrangement (APL). In view of the analysis carried out, it was concluded that the studied locality can be identified as APL of tourism in consolidation phase. In the environmental dimension, it was verified the need to implement public and private actions that direct and potentiate measures that increase tourism activity in a sustainable manner. Specifically, related to reduction of water and energy consumption, use of rainwater, solid waste management and implementation of selective collection. As a result of this work, it is hoped to support the development of public policies directed to the sustainable development of tourism. KEYWORDS Tourism; Clusters; Local Development; Sustainability Indicators; Environment.

Based on field research in the Central African Republic, this article discusses several social and economic challenges to conservation programmes that include community development components. These interrelated challenges include immigration as people elsewhere are attracted to economic opportunities, the lack of tenure of land and natural resources, diversification of economic and subsistence strategies, ethnic diversity and the lack of a conservation ethic. Addressing these challenges requires fundamental socio-economic change.

This paper analyses the impacts of electricity generation from solar energy on the Thai electricity industry. In this paper, three scenarios (REF, Solar2015 and Solar2018) are developed to represent an increased levels of electricity produced from solar energy. A Low Emissions Analysis Platform (LEAP) model is employed, in this paper, to assess the impacts for the period 2019–2037.This paper assesses and analyses the scenario impacts in terms of diversification of electricity generation, fossil fuel requirement and emissions of CO2 and SO2. The analysis reveals that increased electricity generation from solar energy would help diversify energy supply for electricity generation, reduce fossil fuel imports, and therefore help improve energy security of the country. Furthermore, it would help mitigating CO2 and SO2 emissions – an issue of environmental significance. Despite several benefits, there are a number of emerging barriers for promoting electricity generation from solar energy in Thailand. These include the intermittency of solar energy, high-capital cost, unsupportable grid infrastructure and unfavourable regulatory framework. This paper, therefore, suggests that the implementation of energy storage system, provision of financial incentives to potential investors, improvement of grid flexibility and the revision of the regulations to support solar energy business could be effective strategies in order to address the barriers facing the Thai electricity industry.
