Improving access to sustainable energy services and reducing the carbon footprint and deforestation of developing countries presents a substantial challenge to the development industry. This paper aims to critically assess two prevalent business models emerging to meet this challenge: financial institution–technology provider partnerships and the one-stop-shop, pay-as-you-go (PAYG) model. The authors find that collaborations between financial institutions and energy providers need to address grey areas such as product quality standards, marketing, and post-sales services, and incorporate feedback loops to continually evaluate the performance of the partnership. Pay-as-you-go presents an intriguing business case to leapfrog more traditional energy access programmes. However, more robust results from the field need to be reported before the PAYG movement can claim success. Ultimately, collaborative and integrated actions by all stakeholders are needed to achieve universal energy access.

This paper investigates the meaning of systemic risk in energy markets and proposes a methodology to measure it. Energy Systemic Risk is defined by the risk of an energy crisis raising the prices of all energy commodities with negative consequences for the real economy. Measures of the total cost (EnSysRISK) and the net impact (ΔMES) of an energy crisis on the rest of the economy are proposed. The measures are derived from the Marginal Expected Shortfall (MES) capturing the tail dependence between the asset and the energy market factor. The adapted MES accounts for causality and dynamic exposure to common latent factors. The methodology is applied to the European Energy Exchange and the DAX industrial index, where a minor decline in industrial productivity is observed from recent energy shocks.

Abstract Floods are challenging the resilience of societies all over the world. In many countries there are discussions on diversifying the strategies for flood risk management, which implies some sort of policy change. To understand the possibilities of such change, a thorough understanding of the forces of stability and change of underlying governance arrangements is required. It follows from the path dependency literature that countries which rely strongly on flood infrastructures, as part of flood defense strategies, would be more path dependent. Consequently there is a higher chance to find more incremental change in these countries than in countries that have a more diversified set of strategies. However, comparative and detailed empirical studies that may help scrutinize this assumption are lacking. To address this knowledge gap, this paper investigates how six European countries (Belgium, England, France, The Netherlands, Poland and Sweden) essentially differ with regard to their governance of flood risks. To analyze stability and change, we focus on how countries are responding to certain societal and ecological driving forces (ecological turn; climate change discourses; European policies; and the increasing prevalence of economic rationalizations) that potentially affect the institutional arrangements for flood risk governance. Taking both the variety of flood risk governance in countries and their responses to driving forces into account, we can clarify the conditions of stability or change of flood risk governance arrangements more generally. The analysis shows that the national-level impact of driving forces is strongly influenced by the flood risk governance arrangements in the six countries. Path dependencies are indeed visible in countries with high investments in flood infrastructure accompanied by strongly institutionalized governance arrangements (Poland, the Netherlands) but not only there. Also more diversified countries that are less dependent on flood infrastructure and flood defense only (England) show path dependencies and mostly incremental change. More substantial changes are visible in countries that show moderate diversification of strategies (Belgium, France) or countries that ‘have no strong path yet’ in comprehensive flood risk governance (Sweden). This suggests that policy change can be expected when there is both the internal need and will to change and a barrage of (external) driving forces pushing for change.

Abstract This paper investigates the impact of urbanization on energy consumption by applying the Stochastic Impacts by Regression on Population, Affluence and Technology (STIRPAT) in case of Malaysia. The study covers the time period of 1970Q1–2011Q4. The unit root test and the ARDL bounds testing approach have been applied to examine integrating properties and long run relationship in the presence of structural breaks. Our results validated the existence of cointegration and exposed that urbanization is a major contributor in energy consumption. Affluence raises energy demand. Capital stock boosts energy consumption. Trade openness leads to affluence and hence increases energy consumption. The causality analysis finds that urbanization Granger causes energy consumption. The feedback effect is found between energy consumption and affluence and, energy consumption and capital. The bidirectional causality exists between trade openness and energy consumption.

Le changement d'utilisation des terres/de couverture est la principale cause de dégradation des écosystèmes terrestres. Cependant, ses impacts seront exacerbés en raison du changement climatique et de la croissance démographique, entraînant une expansion agricole en raison de la demande accrue de denrées alimentaires et de la baisse des rendements agricoles dans certaines zones tropicales. Les stratégies internationales visant à atténuer les impacts du changement climatique et du changement du couvert terrestre sont difficiles dans les régions en développement. Cette étude vise à évaluer des alternatives pour minimiser les impacts de ces menaces dans le cadre de trajectoires socio-économiques, dans l'une des régions les plus biologiquement riches du Guatemala et du Mexique. Cette étude est située dans le bassin versant d'Usumacinta, une région transfrontalière qui partage une histoire commune, avec des propriétés biophysiques et des contraintes économiques similaires qui ont conduit à d'importants changements dans l'utilisation/la couverture des terres. Pour comprendre les impacts sur la déforestation et les émissions de carbone des différentes pratiques de gestion des terres, nous avons développé trois scénarios (1) : le statu quo (BAU), (2) un scénario de réduction des émissions visant à réduire la déforestation et la dégradation (REDD+) et (3) zéro déforestation à partir de 2030 sur la base des engagements internationaux. Nos résultats suggèrent que d'ici 2050, la couverture terrestre naturelle pourrait réduire de 22,3 et 12,2% son étendue dans les scénarios BAU et REDD +, respectivement par rapport à 2012. Cependant, le scénario zéro déforestation montre que d'ici 2050, il serait possible d'éviter de perdre 22,4 % du bassin versant boisé (1,7 million d'hectares) et d'en récupérer 5,9 % (0,4 million d'hectares). En termes de séquestration du carbone, les projets REDD + peuvent réduire les pertes de carbone dans la végétation naturelle, mais une politique de zéro déforestation peut doubler la séquestration du carbone produite par les projets REDD + uniquement. Cette étude montre que pour réduire les pressions sur les écosystèmes, en particulier dans les régions fortement marginalisées avec des migrations importantes, il est nécessaire de mettre en œuvre des politiques transfrontalières de gestion des terres qui intègrent également des stratégies de réduction de la pauvreté. El cambio en el uso/cobertura de la tierra es la principal causa de la degradación de los ecosistemas terrestres. Sin embargo, sus impactos se exacerbarán debido al cambio climático y al crecimiento de la población, impulsando la expansión agrícola debido a una mayor demanda de alimentos y menores rendimientos agrícolas en algunas áreas tropicales. Las estrategias internacionales destinadas a mitigar los impactos del cambio climático y el cambio en la cobertura del uso de la tierra son un desafío en las regiones en desarrollo. Este estudio tiene como objetivo evaluar alternativas para minimizar los impactos de estas amenazas bajo trayectorias socioeconómicas, en una de las regiones biológicamente más ricas de Guatemala y México. Este estudio se encuentra en la cuenca de Usumacinta, una región transfronteriza que comparte una historia común, con propiedades biofísicas y limitaciones económicas similares que han llevado a grandes cambios en el uso/cobertura de la tierra. Para comprender los impactos en la deforestación y las emisiones de carbono de las diferentes prácticas de gestión de la tierra, desarrollamos tres escenarios (1): negocios como siempre (BAU), (2) un escenario de reducción de emisiones destinado a reducir la deforestación y la degradación (REDD+) y (3) cero deforestación a partir de 2030 en función de los compromisos internacionales. Nuestros resultados sugieren que para 2050, la cobertura natural de la tierra podría reducir el 22.3 y el 12.2% de su extensión bajo los escenarios BAU y REDD +, respectivamente, en comparación con 2012. Sin embargo, el escenario de deforestación cero muestra que para 2050, sería posible evitar la pérdida del 22,4% de la cuenca forestal (1,7 millones de ha) y recuperar el 5,9% (0,4 millones de hectáreas) de la misma. En términos de secuestro de carbono, los proyectos REDD + pueden reducir las pérdidas de carbono en la vegetación natural, pero una política de deforestación cero puede duplicar el secuestro de carbono producido solo por los proyectos REDD +. Este estudio muestra que para reducir las presiones sobre los ecosistemas, particularmente en regiones altamente marginadas con una migración significativa, es necesario implementar políticas transfronterizas de gestión de la tierra que también integren estrategias de alivio de la pobreza. Land-use/cover change is the major cause of terrestrial ecosystem degradation. However, its impacts will be exacerbated due to climate change and population growth, driving agricultural expansion because of higher demand of food and lower agricultural yields in some tropical areas. International strategies aimed to mitigate impacts of climate change and land use-cover change are challenging in developing regions. This study aims to evaluate alternatives to minimize the impacts of these threats under socioeconomic trajectories, in one of the biologically richest regions in Guatemala and Mexico. This study is located at the Usumacinta watershed, a transboundary region that shares a common history, with similar biophysical properties and economic constraints which have led to large land use/cover changes. To understand the impacts on deforestation and carbon emissions of different land-management practices, we developed three scenarios (1): business as usual (BAU), (2) a reducing emissions scenario aimed to reduce deforestation and degradation (REDD+), and (3) zero-deforestation from 2030 onwards based on the international commitments. Our results suggest that by 2050, natural land cover might reduce 22.3 and 12.2% of its extent under the BAU and REDD + scenarios, respectively in comparison with 2012. However, the zero-deforestation scenario shows that by 2050, it would be possible to avoid losing 22.4% of the forested watershed (1.7 million ha) and recover 5.9% (0.4 million hectares) of it. In terms of carbon sequestration, REDD + projects can reduce the carbon losses in natural vegetation, but a zero-deforestation policy can double the carbon sequestration produced by REDD + projects only. This study shows that to reduce the pressures on ecosystems, particularly in regions highly marginalized with significant migration, it is necessary to implement transboundary land-management policies that also integrate poverty alleviation strategies. استخدام الأراضي/تغيير الغطاء هو السبب الرئيسي لتدهور النظام الإيكولوجي الأرضي. ومع ذلك، ستتفاقم آثاره بسبب تغير المناخ والنمو السكاني، مما يؤدي إلى التوسع الزراعي بسبب ارتفاع الطلب على الغذاء وانخفاض الغلة الزراعية في بعض المناطق الاستوائية. تشكل الاستراتيجيات الدولية الرامية إلى التخفيف من آثار تغير المناخ وتغير استخدام الأراضي تحدياً في المناطق النامية. تهدف هذه الدراسة إلى تقييم البدائل لتقليل آثار هذه التهديدات في إطار المسارات الاجتماعية والاقتصادية، في واحدة من أغنى المناطق بيولوجيًا في غواتيمالا والمكسيك. تقع هذه الدراسة في مستجمع مياه أوسوماسينتا، وهي منطقة عابرة للحدود تشترك في تاريخ مشترك، مع خصائص فيزيائية حيوية مماثلة وقيود اقتصادية أدت إلى تغييرات كبيرة في استخدام الأراضي/تغطيتها. لفهم تأثيرات ممارسات إدارة الأراضي المختلفة على إزالة الغابات وانبعاثات الكربون، وضعنا ثلاثة سيناريوهات (1): العمل كالمعتاد (BAU)، (2) سيناريو خفض الانبعاثات الذي يهدف إلى الحد من إزالة الغابات وتدهورها (REDD+)، و (3) إزالة الغابات الصفرية اعتبارًا من عام 2030 فصاعدًا بناءً على الالتزامات الدولية. تشير نتائجنا إلى أنه بحلول عام 2050، قد يقلل الغطاء الأرضي الطبيعي بنسبة 22.3 و 12.2 ٪ من مداه في إطار سيناريو العمل الاعتيادي وسيناريو خفض الانبعاثات الناجمة عن إزالة الغابات وتدهورها في البلدان النامية، على التوالي مقارنة بعام 2012. ومع ذلك، يُظهر سيناريو إزالة الغابات الصفرية أنه بحلول عام 2050، سيكون من الممكن تجنب فقدان 22.4 ٪ من مستجمعات المياه الحرجية (1.7 مليون هكتار) واستعادة 5.9 ٪ (0.4 مليون هكتار) منها. من حيث عزل الكربون، يمكن لمشاريع خفض الانبعاثات الناجمة عن إزالة الغابات وتدهورها في البلدان النامية أن تقلل من خسائر الكربون في الغطاء النباتي الطبيعي، ولكن سياسة إزالة الغابات الصفرية يمكن أن تضاعف عزل الكربون الناتج عن مشاريع خفض الانبعاثات الناجمة عن إزالة الغابات وتدهورها في البلدان النامية فقط. تُظهر هذه الدراسة أنه للحد من الضغوط على النظم الإيكولوجية، لا سيما في المناطق المهمشة للغاية مع الهجرة الكبيرة، من الضروري تنفيذ سياسات إدارة الأراضي العابرة للحدود التي تدمج أيضًا استراتيجيات التخفيف من حدة الفقر.

Highlights •Biomass resource constraints impact the effectiveness of bioeconomy policies. •Bioeconomy policies may have an important impact on the sector structure in the long run, but the sector growth remains ultimately constrained by the availability of inputs. •Solutions to reduce the biomass constraint have to be included in innovation policy for the biobased economy.

Climate change is worsening the number, frequency and duration of natural hazards across the globe, making disaster risk reduction and resilience building among the most pressing challenges ahead. According to UN-Habitat, informal settlements are where the impacts of climate change are the most acute in urban areas and strengthening resilience in these neighbourhoods represents a very complex yet urgent challenge. Today, urban areas are home to 56 per cent of the world’s population and this figure is projected to increase to 60 per cent by 2030 and 68 per cent by 2050, with 90 per cent of the growth by 2050 expected to occur in less developed economies. In these countries, population growth and displacement (including climate-driven migrations) will lead to rapid and unplanned urbanisation forcing a growing number of people into informal settlements. Currently, one billion people live in informal settlements, mostly in Asia, Sub-Saharan Africa and Latin America and this figure is expected to grow to 3 billion in 2050.

The European Union is currently in the process of transformation toward a circular economy model in which different areas of activity should be integrated for more efficient management of raw materials and waste. The wastewater sector has a great potential in this regard and therefore is an important element of the transformation process to the circular economy model. The targets of the circular economy policy framework such as resource recovery are tightly connected with the wastewater treatment processes and sewage sludge management. With this in view, the present study aims to review existing indicators on resource recovery that can enable efficient monitoring of the sustainable and circular solutions implemented in the wastewater sector. Within the reviewed indicators, most of them were focused on technological aspects of resource recovery processes such as nutrient removal efficiency, sewage sludge processing methods and environmental aspects as the pollutant share in the sewage sludge or its ashes. Moreover, other wide-scope indicators such as the wastewater service coverage or the production of bio-based fertilizers and hydrochar within the wastewater sector were analyzed. The results were used for the development of recommendations for improving the resources recovery monitoring framework in the wastewater sector and a proposal of a circularity indicator for a wastewater treatment plant highlighting new challenges for further researches and wastewater professionals.
