Uso de herramientas para mejorar la calidad de vida en el Municipio de Julimes a través de cooperativas agrícolas

Uno de los principales problemas de las pequeñas unidades agrícolas rurales es establecer e implementar un modelo de gestión para aprovechar sus potencialidades, e impulsar el desarrollo productivo. El siguiente trabajo plantea la unión de los pequeños productores del Municipio de Julimes, Chihuahua, para la formación de una cooperativa agrícola, la cual pueda agregarles el valor correspondiente a los productos, conservándolos para poder comercializarlos y tenerlos como una herramienta sustentable de desarrollo dentro del municipio. Para determinar los factores que inciden en la producción se crearon mapas, así como los análisis de suelos para identificar los sistemas de cultivos y caracterizar las unidades agropecuarias, para el análisis de los diferentes factores, se utilizó un análisis descriptivo combinando herramientas de investigación. Se definió una muestra de 87 productores, a los cuales se les aplicó una encuesta debidamente formulada. Los resultados señalan, que el producto que se cosecha con mayor regularidad es el chile, mientras que éste es el que genera más ingresos, los productores opinaron que dentro de la población, existe una persona intermediaria al momento de vender sus productos, por lo cuál, optan por pertenecer y participar en una cooperativa agrícola.

La patrimonialización de las salinas tradicionales: una herramienta para el desarrollo local

La patrimonialización de las salinas tradicionales en desuso puede ser una forma no sólo de recuperar su patrimonio, sino también una herramienta para el desarrollo local sostenible que va más allá de estos valores. Un estudio realizado en doce salinas europeas (nueve en España y tres en Dinamarca, Eslovenia y Francia, respectivamente) que se encuentran en diferentes etapas de patrimonialización muestra diferentes estrategias de recuperación del patrimonio; los obstáculos que se han encontrado en el camino y cómo (algunos de ellos) se han resuelto. Mediante un estudio comparativo de estas salinas, podemos identificar buenas prácticas y sacar conclusiones sobre lo que funciona o no a la hora de valorar el patrimonio natural, cultural y humano de estos espacios. En los doce casos se pueden observar diferentes grados de patrimonialización, algunos incipientes, otros en curso y otros ya consolidados; y se explican las diferencias entre ellos. Los procesos consolidados son los que muestran cómo el carácter multifuncional de los paisajes salados puede utilizarse para ofrecer una amplia gama de productos y servicios que van más allá de la producción de sal. Todos los casos, antes de su abandono, eran paisajes productivos dedicados al monocultivo de la sal, sin interés en preservar sus valores naturales y culturales más allá de lo estrictamente necesario para garantizar una mínima productividad. Las enseñanzas extraídas de los casos estudiados pueden servir de modelo para otros tipos de patrimonio productivo modesto en las zonas rurales. Asimismo, se discuten los retos de futuro en la patrimonialización de las salinas.

Diversification as a tool for sustainable development of rural areas in the con-text of decentralization

The article substantiates diversification as a tool to ensure sustainable development of rural areas in decentralization, which contributes to increasing incomes of the rural population, increasing gross agricultural and non-agricultural products, ensuring the competitiveness of rural areas, achieving economic, food and environmental safety, rational use, protection and reproduction of natural resources. In the process of researching the level of sustainable development of rural areas, monographic and graphic methods and scientific generalization were used. The study identified internal factors that affect the sustainable development of rural areas. Social factors include living conditions, the situation on the labor market, the state of social infrastructure. Economic factors should include the provision of agricultural land, the state of diversification of agricultural and non-agricultural activities, the amount of investment in economic development, the level and structure of household income in rural areas. Environmental factors include the level of air pollution, the situation with waste, the use of freshwater, the application of fertilizers to soils, the production and restoration of forests, the level of investment in environmental protection. External factors influencing the sustainable development of rural areas include the political situation in the country and the world; decentralization process; state programs to support rural development and agriculture; the level of supply and demand for goods and services produced in a particular area, etc. It is substantiated that diversification is a tool to ensure sustainable development and strengthen the competitive advantages of rural areas. It is stipulated that attracting investments in rural development and diversification of economic activity will contribute to job creation; income growth of rural residents; the revival of local crafts, customs and crafts, improvement of villages and change of consciousness of villagers. Further research should be carried out in the direction of calculating the integrated index of sustainable development of rural areas in Ukraine to identify regional disparities in the social, economic and environmental spheres of the functioning of these areas in the context of decentralization.

Renewable Energy Applications for Sustainable Agricultural Systems

Sustainable agriculture means meeting current food needs without compromising the ability of current or future generations to meet their own needs. Energy is the most important tool for sustainable agricultural development and growth. The agri-food chain accounts for around 30 % of the global energy demand. The agricultural sector is currently heavily dependent on the use of fossil fuels. The use of fossil fuels in agriculture leads to an increase in greenhouse gas (GHG) emissions in the sector. The total GHG emissions from the agri-food chain account for more than 30 % of global GHG emissions per year. Emissions from energy used in agricultural activities consist primarily of CO2, CH4, and N2O. Current fossil fuel-based energy generation needs to be shifted to renewable energy such as solar, biomass, wind, and geothermal to mitigate climate change and reduce GHG emissions. There are a variety of energy-related mitigation and adaptation opportunities in agriculture. Improvements will be made by enhancing access to electricity, making more efficient use of resources, and increasing the use of renewable energy sources in agriculture. This would have the dual advantage of providing renewable energy inputs to agriculture, thereby increasing productivity, economic and social sustainability, and reducing climate change commitments. This paper details the role of renewable energy in agriculture by linking sustainability aspects.

The use of tourism as a social intervention in indigenous communities to support the conservation of natural protected areas in Mexico

Tourism has been considered a tool for sustainable development (SD) of rural/indigenous communities living within natural protected areas (NPAs) since the 1980s. This article examines the use of tourism as a SD intervention in the management of NPAs. Based on the theory of social change and on the realist methodological approach to social research, the study focuses on the case of Mexico. It seeks to establish causal chains to identify mechanisms that trigger (un)expected outcomes within a specific sociocultural context. The research distinguishes between development of tourism, and SD through tourism. Preliminary findings from on-going research in the indigenous community of Sta. Cruz Tepetotutla in Oaxaca, Mexico point to the necessity for an alternative approach to the design, application and assessment of tourism interventions. It is argued that specific contextual features trigger mechanisms which lead to (un)expected outcomes. Considering traditional social organization is fundamental to achieve improvement in collective well-being, biodiversity preservation and cultural heritage. The article seeks to help decision-makers improve their outcomes from interventions, and to generate further discussion on the use of tourism for the management of NPAs, and on the role tourism can play in the improvement of the living conditions of the communities.

Proposing SMaR²T-ATi, an assessment tool for urban sustainable development and experimentation on Eucalyptus municipal territory, Algiers province

In developed and developing countries, many metropolitan cities are confronted with rapid unsustainable growth. The purpose of this article is to propose an assessment tool for the management of suburban territories, which will help enforce sustainable development strategies.The methodology used is based on a modelling approach resulting from system theory and systemic causality. The method allowed us to build a generic tree model of threshold index, and later the SMaR²T – ATi assessment tool and its three (3) levels of thresholds aggregated indicators: acceptable, critical or unacceptable.The tool is experimentally tested for the municipality of Eucalyptus in the suburbs of Algiers. The choice of the methodology was driven by the availability of multiple peer-review studies and reports on the unsustainable growth of the area. Based on some reliable indicators, results show levels of unacceptable thresholds as well as irreversible damage. The findings of this study provide multiple-choice for concrete solutions for the future of the Eucalyptus territory.Research provides opportunities to adapt the method of limit states in suburban land management; and to generalise experimentation to other suburban cities in the Algiers and elsewhere metropolitan area.

Tools for Sustainable Development of Regional Energy Systems

Nowadays, it is relevant to consider changes in the structure of the fuel and energy balance of industrial regions and the availability of imported fuel and energy resources, especially in the areas that lack energy sources. The ongoing structural shifts in energy consumption systems and the growing uncertainty in energy markets encourage the development of tools for improving the sustainable development of regional energy systems. To refine the theoretical and methodological basis of the study, we defined its conceptual framework, described the difference s betwee n sustainabl e functionin g an d developmen t o f th e energy sector and determined the factors of its regional differentiation and manifestations of the energy crisis. Further, we identified the shortcomings of the existing methods for forecasting the demand for electricity. We paid special attention to quality factors of strategic planning in the region, in particular, the used statistics and documents. Based on the analysis of integrated resource planning (IRP) methodology, our experience in forecasting fuel and energy balances, assessment of sectoral indicators of energy efficiency and energy demand in the region, we proposed a model for predictive and analytical justification of regional programmes for energy development. Such a model significantly increases the information reliability of these programmes’ implementation. Considering organisational tools to support sustainable development, we developed a regional energy management scheme and a mechanism stimulating local energy companies to improve energy efficiency in the consumption sector, enhance regional competition and attract investments in the renewal of fixed assets. The study has practical significance due to recommendations and tools for adjusting regional energy policy based on the coordination of the predicted parameters for various participants in the energy supply process.

Knowledge, attitude and practice towards health research and its utilization among health professionals in Bhutan: Results of a nationwide cross-sectional survey in 2019.

Research is an important tool for sustainable development and the advancement of health. In Bhutan, the need for strengthening the national health research effort has been recognized only in recent years. As a part of research capacity building, this study was conducted to assess the knowledge, attitude and practices of the country's health care professionals towards research. This was a nationwide cross-sectional study. Simple random sampling was used to obtain a proportionate composition of health professionals. A self-administered questionnaire was developed to assess knowledge through 10 multiple-choice questions, attitude through rating statements, and practices through assessing experiences with research. Knowledge was scored out of 10. Besides analysing proportions, correlation and simple linear regression coefficients were calculated to assess the association of knowledge score with age, work experience, qualification, and the number of research projects undertaken. A total of 420 valid questionnaires were collected (response rate = 95.2%). The mean knowledge score was 6.2 (±2.0) out of 10. There was a negative correlation between the knowledge score and the participant's age (r = -0.15, p = 0.002) and work experience (r = -0.17, p < 0.001). Participants' knowledge score increased by 0.58 (95% CI: 0.50-0.65, p < 0.001) for each unit increase in qualification level and by 0.75 (95%CI: 0.64-0.87, p < 0.001) for every research project conducted. The majority believed that local research would contribute to better clinical decision making (92.8%) by building local evidence (90.3%). Four out of five participants expressed interest in conducting research. However, only 27.4% had ever conducted research, 6.0% had published in journals and 4.3% had presented in scientific conferences. Less than half of the respondents had read (35.2%) or participated in discussions (42.1%) of research articles in their workplace. The major challenges were lack of knowledge (61.2%), time (49.9%) and resources to undertake literature searches (42.6%). Self-reported knowledge about health research was fair, and the conduct of research and utilization of research articles were poor. However, the majority hold positive attitudes and there is a need for supporting professional development in this area.

Land use planning as tool for sustainable development

The purpose of the article is to evaluate role of land use planning project (hereinafter - LUPP) specified in the legislation of Latvia in sustainable development of territory. In Land Use Planning Law adopted in 2006, LUPP is project for arrangement of territory and measures of improvement of land use conditions, for part of an administrative territory of local government, separate immovable property or land parcel, which is developed for exchange of land parcels or elimination of inter-areas, for reorganisation of land parcel boundaries, as well as for subdivision of land parcels. In Latvia for sustainable development of the territory, legislative acts of spatial development planning system have been adopted at several levels, from which for detailed arrangement of territory detailed plan should be developed. The detailed plan often includes reorganisation of land parcel boundaries, but legislation determines that detailed plan should be developed in territories specified in spatial plan, mainly before commencing new construction. The LUPP is not planning instrument for territory development and may be developed in territories in which regulatory framework do not provide development of detailed plan. However, in local governments it is relatively common that for areas intended, for example, for individual building, for subdivision of land parcels, LUPP rather than detailed plan has been choosen to develop. In order to clarify these concerns, the study carried out survey of specialists of local governments and the article summarises analysis of results about development of LUPP in relevant local governments, as well as, on the basis of relevant regulatory enactments, compared the objectives and conditions for development of LUPP and detailed plan.

Compensation fund as a tool for sustainable development of the Arctic indigenous communities

The paper examines the approaches to the formation of compensation funds for the indigenous peoples during Arctic industrial development. The key challenge is the technical problem-solving of reconciling the rights of indigenous peoples and the interests of the mining company. The compensation fund allows harmonizing the interests of stakeholders. In 2020, Russia adopted the Arctic Development Strategy that supposes the implementation of investment projects, social and economic development, improving the quality of life of the local population as well as a creation of stable financial basis for traditional lands. The case-study of Yakutia is analyzed in the paper. The authors consider the possibilities to develop compensation funds on the base of economic, social and cultural impact assessment to fulfill them by the costs of extractive companies. The proposed mechanisms help generate additional income and accumulate financial capital for future generations. The mathematical tools and methods allow problem-solving on assessment of the priority compensation projects, the development of procedure for their implementation and the investment approach for the indigenous participation in the projects of extractive companies. The data for calculations was collected by the authors during field work on the impact assessment of mining projects in the Arctic Yakutia in 2016–2020.

Barierrs to Implementing the Concept of Green Human Resource Management: The Case of Poland

Purpose: The Green Human Resource Management concept is relatively new to Polish managers. There is a research gap with respect to investigating the reasons behind limited practical implementation of GHRM. The objective of the study is the identification of major barriers to the implementation of the GHRM concept in Polish companies. Design/Methodology/Approach: The study was conducted in 2018 on a random sample of 300 Polish enterprises. The respondents were managers responsible for HR policy development. The method used in the study was CATI. In the first stage of the analysis, an assessment of the level of implementation of the GHRM concept in 7 functional areas was carried out with the use of a 5-point Likert scale. The second stage involved identification of the main barriers impeding the implementation of green HR practices. Findings: Green Human Resource Management viewed as the latest research tendency plays a crucial role in the strategies of corporate sustainable development. However, studies demonstrate that the level of GHRM implementation in Polish companies is low. In the course of the analysis, it appeared that the primary barriers limiting GHRM implementation are: limited financial means, lack of incentives to engage in environmentally friendly activities, low competencies of the management with respect to sustainable HRM, no or low effectiveness of GHRM tools and a culture based on economic values. Practical Implications: If the major barriers to GHRM implementation are identified and Polish managers become aware of them, barrier removal may prove easier and, consequently, the scope of implementation of green practices within the HR function may be broadened. Originality/Value: This article is a pioneer attempt to identify the barriers to Green HRM implementation in Poland. The research enriches the still limited set of literature concerning environmental practice performance in the area of HR. The author believes that the results of the presented research may stimulate interest in GHRM concept’s implementation in Polish companies as a tool of corporate sustainable development.

Groundwater quality assessment for different uses using various water quality indices in semi-arid region of central Tunisia

The Hajeb Layoun-Jelma basin, located in the central Tunisia, is the principal source of water supply for Sidi Bouzid and Sfax region. The over-abstraction from this groundwater, since 1970, and the intensive agriculture activities led to the degradation of the water quantity and quality. The quality evaluation for this groundwater is very important tool for sustainable development and decision for water management. A total of 28 groundwater samples, from shallow, springs, and deep aquifers, were collected, storage and analyzed to evaluate its quality suitability for domestic and agriculture purposes using geographic information system and geochemical methods. For the both aquifers, the abundance of cations: Na > Mg > Ca > K, and of anions in the order: Cl > HCO3 > SO4. The dominant hydrochemical facies, for the shallow aquifer and springs, are Na-Cl and Ca-Mg-Cl; for the deep aquifer, the geochemical facies are Na-Cl, Ca-Mg-Cl, and Ca-Cl. The comparison of the major parameters and the chemical data with the World Health Organization standards and the national standards indicate that this groundwater is suitable for drinking, except in some samples, with high salinity concentrations. The water quality was assessed, for drinking uses, using “water quality index,” “entropy,” and “improved water quality index.” The results mentioned that the improved water quality index is the best method which indicated that the poor water quality coincide with the Na-Cl water type. The entropy method and the water quality index present the optimistic methods. The irrigation suitability assessment was made using various parameters (SAR, TH, % Na, PI, MH, KR, EC). The results revealed that the majority of samples in Hajeb Layoun-Jelma basin are not appropriate for irrigation uses.

Sustainable Development Tool Using Meta‐Analysis and DPSIR Framework — Application to Savannah River Basin, U.S.

AbstractThe Savannah River Basin (SRB), a highly stressed southeastern river in United States is a conservation priority for State, Federal government, and nongovernment organizations. A four‐stage sustainable development tool was developed in this study using meta‐analysis and the drivers–pressures–state–impacts–responses (DPSIR) framework. Through the synthesis of ~150 references in the SRB this study addressed three research questions: (1) What were the drivers, pressures, state, impacts, and responses (components of DRSIR framework) in SRB (2) Can these components be grouped together from various studies in SRB (3) Can causal chain/loops be developed, and will they be useful for policy and decision making? First in the Stage 1, the state of the SRB was represented (S component of DPSIR), in Stage 2, the drivers–pressures–impacts–responses (DPIR components of DPSIR) were represented, in the third stage (Stage 3) the common units characterizing each DPSIR component were identified. Finally, in Stage 4, the causal chains/loops were developed and organized into scientific research at a level appropriate for building better understanding about SRB and helping stakeholders and policy makers in managing basin sustainability challenges. Although the tool was applied to SRB, the methodology is applicable to other river basins and ecosystems.

Assessment of Natural and Post-Extraction Biomass from Acrocomia totai leaves: a Renewable Source of Energy

The search for cleaner production technologies and sustainable development tools has prompted increasing interest in the use of new, renewable raw materials for biorefineries and energy production. Thus, biodiesel production from the pulp oil (fruit oil) of Acrocomia totai Mart., a species of palm tree, is currently being investigated. However, the bioenergy potential of biomass from different parts of this species is still unknown, and may not be limited to oil from the pulp. Therefore, the aim of this work was to evaluate the leaves of A. totai as a secondary source of lipids and energy. Deciduous and fresh leaves were submitted to the Soxhlet and Bligh & Dyer extractions, and the presence of 1.0 to 5.8% of unsaturated fatty acids was observed by GC-FID analyses. The crude extract (CE) of the leaves was obtained by exhaustive extraction with methanol and then partitioned with different solvents. CE and its fractions were characterized by 1H nuclear magnetic resonance (NMR) spectroscopy, and the thermal properties were determined. The average specific heat of the grease fractions was 2.0 J g−1 K−1 and the calorific value of the polar and non-polar fractions varied from 15.7 to 34.1 MJ kg−1. For the whole leaves, the calorific value of the deciduous leaves was higher than that of the fresh leaves due to their lower water content, as determined by thermogravimetric-differential thermal analyses (TG-DTA) and infrared (IR) spectroscopy. The residual pies from the Soxhlet extractions of the deciduous and fresh leaves were characterized by TGA-DTA and scanning electron microscopy (SEM), revealing a lignocellulosic fibrous material with calorific values of 14.2 MJ kg−1 and 9.3 MJ kg−1, respectively, and an average specific heat of 1.6 J g−1 K−1. These thermal properties are comparable to those of sugarcane bagasse, a widely used type of biomass for industrial large-scale bioenergy production in Brazil. Therefore, these results indicated that it may be possible to harvest the deciduous leaves, a residue from the “macauba” cultivation, for energy cogeneration in biodiesel refineries.

The importance and relevance of sustainable development for modern society and the environment are highlighted. The importance of the production of medicinal plants in today's conditions and the need for its development are revealed. The relationship between sustainable development and the production of medicinal plants is revealed. In particular, emphasis is placed on the relationship between the functions of the medicinal plant industry and the goals and objectives of sustainable development. It is noted that the production of medicinal plants has a direct impact on the implementation of environmental goals of sustainable development. Alternative methods of agricultural production are presented, among which regenerative agriculture is singled out. The role and significance of regenerative agriculture and its connection with the production of medicinal plants are revealed. The goals and principles of regenerative agriculture are highlighted. In particular, it is stated: the practical meaning of regenerative agriculture is that farmers use a system of crop rotation, diversify crops and animals, minimize tillage, do not contaminate soil and water with chemicals. It is emphasized that regenerative agriculture as an approach to management is really complex. It envisages not only the restoration of ecosystems and biodiversity, but also the improvement of economic performance of agricultural producers. It is revealed that the basic principles of regenerative agriculture correspond to the production of medicinal plants. In this regard, the principles of functioning of the industry of production medicinal plants are also presented. An analysis of «Sustainable Development Goals: Ukraine» was made. He confirmed that the need to develop the production of medicinal plants on the basis of regenerative agriculture is extremely important for Ukraine. A set of tools for sustainable development in general and agricultural production in particular has been formed. It is substantiated that the observance of the set of methodological principles of regenerative agriculture and the field of production of medicinal plants can lead to a positive synergetic effect.

Measurement and modeling of CO2 solubility in binary aqueous DMSO and MDEA and their ternary mixtures at different temperatures and compositions

CO2 capturing is an industrial tool in worldwide sustainable development to reduce the greenhouse effect. In this study, the new experimental vapor-liquid equilibrium (VLE) data for CO2 solubility in the mixtures of physical and chemical solvents were investigated. The carbon dioxide solubility measurements were carried out using a quasi-static method through the DMSO (10 wt.%) +H2O and sulfolane (20 wt.%) +H2O systems at the temperatures of 328.15 and 343.15 K and pressure up to 3554 kPa. Moreover, the CO2 partial pressure against its gas loading was obtained for the DMSO+MDEA+H2O system at the compositions of (10-40-50), (20-40-40) wt. %, 328.15, 343.15 K, and pressure up to 3343 kPa. The influence of the physical solvents such as sulfolane and DMSO in the aqueous MDEA mixtures on CO2 solubility was studied. We showed that DMSO was more effective than sulfolane in the absorption of CO2. Finally, using the ion-pair concept, the eNRTL model was used to model the vapor-liquid equilibrium experimental data so that the molecule–molecule, ion pair-molecule binary interaction parameters of this model were obtained. An overall average relative deviation (AAD%) of 10.95 has resulted in the quaternary DMSO+MDEA+H2O+CO2 system.

Public–private partnership as a tool for sustainable development – What literatures say?

AbstractPublic–private partnership (PPP) has been proposed by the United Nations as a tool for Sustainable Development Goals. The perceptions and tendencies of literatures on this concept have, however, not yet been fully investigated. This research fills the perceived gap, by reviewing sustainability‐oriented PPP studies, to better understand the relationship between PPP and sustainable development. A bottom‐up approach is adopted, with the help of a purposely designed database. The concept and development stages of sustainability‐oriented PPP are examined. The research status of sustainability‐oriented PPP is analysed. The increasing popularity of sustainability‐oriented PPP studies is, to a degree, associated with policies of the key global players in PPP. Research gaps and future research trends are suggested. This research contributes to the body of knowledge of sustainability‐oriented PPP and can help researchers and practitioners in better understanding the status, gaps and direction of future efforts regarding sustainability‐oriented PPP.
