This paper examines for the first time the relationship between CO2 emissions and the consumption of renewable and non-renewable energy in Uzbekistan, spanning the period 1985-2020. The analysis uses the Autoregressive Distributed Lags (ARDL) model to estimate the long-run dynamic multipliers and short-run elasticity coefficients of energy consumption variables. Economic factors, such as GDP, are excluded in the analysis as they may cause multicollinearity problems. The empirical results document that in the short- and long-run, hydropower (renewable) energy consumption negatively impacts CO2 emissions per capita, showing a unidirectional causal effect. As regards with non-renewable energy consumption, natural gas and oil energy consumption have a positive impact on CO2 emissions per capita both in the short and long run. Coal consumption positively impacts CO2 emissions in the short run, while it is negative in the long run. Policy measures to enhance the collection of energy from additional renewable energy sources, in particular hydropower, should be taken into account in order to increase the share of renewable energy, and thus, to compensate non-renewable energy consumption which is the main contributor to CO2 emissions. Moreover, solar and wind energy should be explicitly taken into consideration as an additional renewable energy source, which has the lack of attention by policymakers. Furthermore, policy actions, such as the involvement of the private sector into renewable energy projects and the implementation of effective carbon tax policies, could be further options to reduce CO2 emissions.

Les montagnes abritent une part considérable de la population humaine. Environ un milliard de personnes vivent dans des zones montagneuses, qui abritent une riche diversité naturelle et socioculturelle. Aujourd'hui, de nombreuses personnes vivant dans des zones montagneuses du monde entier sont confrontées à des changements fondamentaux de leurs conditions de vie culturelles et économiques. Dans le même temps, les communautés de montagne ont défié les environnements difficiles dans le passé en s'adaptant aux conditions naturelles changeantes et en faisant preuve de niveaux remarquables de résilience. Dans cet article de synthèse, nous fournissons un aperçu complet de la littérature scientifique de langue anglaise sur les sujets liés à la résilience dans les zones de montagne sur la base d'une revue systématique de la base de données documentaire Scopus®. Nous proposons un point de départ structuré pour les interactions science-pratique et les activités concrètes basées sur l'action pour soutenir les moyens de subsistance et renforcer la résilience dans les zones de montagne. Nous suggérons que les lacunes existantes en matière de connaissances puissent être comblées en s'appuyant sur les connaissances locales et en co-créant des solutions avec les communautés. De cette façon, nous pouvons renforcer les capacités d'innovation et amortir activement l'impact des crises tout en soutenant la transformation délibérée vers la durabilité et la régénération pour améliorer davantage la résilience.

Mountains are home to a considerable share of the human population. Around a billion people live in mountainous areas, which harbor rich natural and sociocultural diversity. Today, many people living in mountainous areas worldwide face fundamental changes to their cultural and economic living conditions. At the same time, mountain communities have defied harsh environments in the past by adapting to changing natural conditions and showing remarkable levels of resilience. In this review paper, we provide a comprehensive overview of English-language scientific literature on resilience-related topics in mountain areas based on a systematic review of the Scopus® literature database. We propose a structured starting point for science–practice interactions and concrete action-based activities to support livelihoods and strengthen resilience in mountain areas. We suggest that existing knowledge gaps can be addressed by relying on local knowledge and cocreating solutions with communities. In this way, we can build innovative capacity and actively buffer against the impact of crises while supporting deliberate transformation toward sustainability and regeneration to further enhance resilience. الجبال هي موطن لنسبة كبيرة من السكان. يعيش حوالي مليار شخص في المناطق الجبلية، التي تضم تنوعًا طبيعيًا واجتماعيًا ثقافيًا غنيًا. اليوم، يواجه العديد من الأشخاص الذين يعيشون في المناطق الجبلية في جميع أنحاء العالم تغييرات جوهرية في ظروفهم المعيشية الثقافية والاقتصادية. وفي الوقت نفسه، تحدت المجتمعات الجبلية البيئات القاسية في الماضي من خلال التكيف مع الظروف الطبيعية المتغيرة وإظهار مستويات ملحوظة من المرونة. في ورقة المراجعة هذه، نقدم نظرة عامة شاملة على الأدبيات العلمية باللغة الإنجليزية حول الموضوعات المتعلقة بالمرونة في المناطق الجبلية بناءً على مراجعة منهجية لقاعدة بيانات أدبيات Scopus®. نقترح نقطة انطلاق منظمة للتفاعلات بين العلوم والممارسات والأنشطة العملية الملموسة لدعم سبل العيش وتعزيز القدرة على الصمود في المناطق الجبلية. نقترح أنه يمكن معالجة الفجوات المعرفية الحالية من خلال الاعتماد على المعرفة المحلية وإيجاد حلول مشتركة مع المجتمعات. وبهذه الطريقة، يمكننا بناء قدرات مبتكرة والوقاية بنشاط من تأثير الأزمات مع دعم التحول المتعمد نحو الاستدامة والتجديد لزيادة تعزيز المرونة.

The primary aspiration of this paper is to learn about the effects of economic growth, energy consumption, agriculture and irrigation water consumption and agriculture productivity on environmental pollution in five countries of Central Asia. The data cover the period from 1992 to 2020 by applying panel data models, namely the Panel FMOLS, Panel DOLS and Panel ARDL-PMG approaches. The results indicate that there is a positive long-term impact of economic growth, water productivity, energy consumption and electricity production on CO2 emissions while agriculture value added and trade openness have a negative and statistically significant influence on CO2 emissions in Central Asia. Country specific short-run coefficients from Panel ARDL reveal that energy consumption is the main driver for rise in the level of CO2 emissions in the countries under the study. Indeed, country level analysis generates unique nexus correlation among agriculture, energy and environmental degradation in each country of Central Asia.

Abstract Building performance simulation [BPS] tools are important in all design stages. However, barriers such as time, resources, and expertise inhibit their use in the early design stages. This study aims to develop, as part of decision-support framework, metamodels to assess the thermal discomfort in a naturally ventilated Brazilian low-cost house during early design. The metamodels predict the degree-hours of discomfort by heat and/or by cold as a function of design parameters for three Brazilian cities: Curitiba, Sao Paulo, and Manaus. The key design parameters, related with passive design strategies, are building orientation, shading devices position and dimensions, thermal properties of the walls and roof, window-to-wall ratio, and effective window ventilation area. The method consists of three main stages: (i) baseline model development; (ii) Monte Carlo simulation; (iii) multivariate regression. Overall, the metamodels showed R2 values higher than 0.95 for all climates, except the ones predicting discomfort by heat for Curitiba (R2 =0.61) and Sao Paulo (R2 =0.75). The proposed metamodels can quickly and accurately assess the thermal performance of naturally ventilated low-cost houses. They can be used to guide professionals during the early design stages, and for educational purposes in building design pedagogy.

Climate change is affecting human and geophysical systems in a variety of complex and interdependent ways. For nature-based tourism-dependent communities like those along the North Shore of Lake Superior in Minnesota, impacts to the region’s abundant natural resources can subsequently affect the livelihoods of individuals who depend upon those resources to provide essential ecosystem services and support the region’s economy. Many of the area’s natural and outdoor recreation resources are collaboratively managed, making cooperation essential to address climate change impacts. In this study, we engaged North Shore stakeholders in a climate change risk assessment process through an exploratory application of participatory geographic information systems (PGIS). Stakeholder involvement allows for the co-production of science to deliver locally-relevant data and information. Involving stakeholders through a PGIS-based climate change risk assessment process allows locally-relevant data and information to be represented and visualized spatially. We used PGIS focus groups, as well as pre- and post-surveys, to solicit stakeholders’ perceptions of risk thresholds (i.e., the time scale of impacts) and climate-related risk severity to sites with built infrastructure, natural amenities, and recreation and tourism destinations. The stakeholders’ knowledge, as well as their commitment to their communities and local environments, influenced general perceptions of region-wide climate-related vulnerabilities. The PGIS exercises generated important discussion among stakeholders and shed light on how to more efficiently collect spatially-explicit data and information from stakeholders that can be used to inform mitigation and adaptation efforts.

This research addresses three major problems currently confronting our globe. These problems are the pending energy crisis, the environmental degradation due to waste and the environmental degradation due to the continuous generation of greenhouse gas emissions.

The paper examines ecotourism in the Aral Sea region of Uzbekistan, an area with a fragile environment that has faced ecological crises and requires careful sustainable development. It looks at the supply side of ecotourism by examining Uzbekistani tour operators’ awareness of benefits derivable from promoting ecotourism in the region, and the local tourism industry’s motives to engage in this development. As a research methodology, the results of an exploratory survey of travel agents and tour operators highlight the policy-making and management interventions required for the more effective promotion and development of ecotourism in the Aral Sea region. The paper analyzes the challenges and opportunities associated with promoting ecotourism activities in the Aral Sea region in pursuit of sustainable regional development, improved livelihood for the local population, employment opportunity and income source creation, and enriched service exports. Key findings from the study show that stakeholders are aware of ecotourism’s value and are motivated to implement ecotourism in the region, but they have limited experience, competence, and international networks to promote and market ecotourism products and services. Local stakeholders have raised the issue that infrastructure development and access to microfinance are their greatest needs from local authorities in Uzbekistan.

Cultural heritage-specific research is scarce within the climate change literature and climate change policy documents, challenging climate adaptation efforts to minimize adverse impacts on cultural heritage. Engaging and assessing diverse stakeholders' values and integrating those with evidence-based knowledge is critical for timely, effective and transparent preservation and climate adaptation of coastal cultural heritage. This study assessed technical experts' and community groups' opinions about the importance of value-based prioritization considerations to provide more immediate guidance adaptation planning and decision making. The findings from four separate elicitation surveys demonstrated substantial consistency in value-based climate adaptation prioritization preferences for one type of vulnerable cultural heritage: historic buildings in coastal zones in the United States. In particular, the samples of cultural heritage professionals and members of community groups consistently rated spatial importance, uniqueness, and scientific value of historic buildings as very important considerations for climate adaptation prioritization decision-making. Also, consistently evaluated but of relatively low importance were considerations related to the cost of preservation and adaptation treatments, including previous investments. Few statistically significant differences were found among our samples in their perceptions of importance. These findings provide initial guidance to cultural heritage managers, particularly those with scarce financial resources to allocate for adapting coastal historic buildings, and demonstrate the need for continued development of approaches that provide rapid assessment of coastal heritage stakeholders' adaptation priorities.
