The research deals with the issue of slums, urban sprawl on agriculture land and its impact on the city of Baghdad. This topic needs close attention because it has become a problem facing the city of Baghdad through recruiting agricultural lands and converting them to residential homes in addition to the transgression on the state lands and building abuses. This research deals with the causes of slums, irregular urban sprawl and risks of excesses on land uses of land in Baghdad. In this research, we try to know the extent to which these problems have affected the city of Baghdad. The research methodology based on the descriptive methodology to clarify the factors affecting urban sprawl at the expense of agricultural land, using studies in government and service institutions and images from satellites to clarify the size of urban sprawl over periods after the 2003 war. Finally, a conclusion and future solutions were set to solve these problems.

In the transition from linear production systems, unsustainable from the point of view of resources, to a model that finds strength in environmental, social and economic sustainability, the circular economy paradigm is the foundation that facilitates the planetary agro-ecological transition. The European Union has taken a number of steps (including the Circular Economy Package of Directives) shaping circularity as a wide-ranging driver measure involving many sectors. The paper intends to provide a regulatory framework on the current general situation regarding circularity in European Union, in order to extrapolate and give evidence to the aspects that intersect the agri-food sector. This is not only because they are poorly addressed in the literature, but also because there is a lack of regulatory instruments on the circular economy specifically addressing this area of interest. For this purpose, the analysis focuses on waste and residue/scrap management issues, recognized by law as by-products and end-of-waste status, as they are covered by circular economy legislation and as they can be applied to the agri-food sector. The latter allow the implementation of circularity strategies in the agri-food sector and, given the numerousness of production chains and the peculiarities of each of them, various regeneration and/or reuse processes of specific resources may be depicted. The intent is to provide useful knowledge on how to implement sustainable waste management, also proposing a concrete case on a by-product of olive oil processing, through which it is possible to highlight how the correct application of regulations favors the adoption of circular economic and management models in the firms involved, as well as informing the relevant economic operators on the possible profiles of legal liability that may arise from insufficient knowledge. Furthermore, this paper delves into the European Green Deal’s Strategy as it enriches the circular economy paradigm with new facets. NextGenerationEU and the National Recovery and Resilience Plan financially support this strategy in the aftermath of the socioeconomic crisis from COVID-19 in the EU Member States. This is in order to achieve the objective of achieving the agro-ecological transition.

Abstract The Chinese government has taken measures to realize energy-savings and emission reductions, such as promoting innovations, adjusting the industrial structure, balancing regional development, and reforming markets. The aim of this paper is to assess the effects of these measures on China's CO2 emissions by using a newly proposed decomposition approach, which identified eight new factors related to the above realistic measures, i.e., energy saving and production technologies, industrial energy and production efficiencies, regional energy and production efficiencies, and pure energy and production efficiencies. The main findings indicate benefits from considerable technological progress in energy-saving and production during 2000–2016 period, and two technological factors contributed the most to emissions abatement and cumulatively reduced 5372.43 Mt and 1291.72 Mt CO2 emissions. The efforts of industrial restructuring promoted energy and production efficiency improvement, which further facilitated emission reduction. In contrast, the pure energy and production efficiency changes cumulatively led to 1080.26 Mt and 1135.85 Mt CO2 emissions growth during the whole sample period, suggesting that severe resource misallocation problems may exist in both the energy market and output market. Additionally, the Chinese government failed to narrow the technology gap between developed regions and underdeveloped regions, further restricting emission reduction.

Abstract This paper employs a new class of computable general–equilibrium (CGE) models, developed in the context of energy-economy-environmental models to simulate the impacts of the EU economy of internal and multilateral instruments for regulation of greenhouse gases (GHGs) emissions. Climate change due to emissions gases of greenhouse gases is a long-term global environmental problem. While specific impacts on different regions as well as their timing are yet uncertain, it is reasonable to suppose that unilateral voluntary action by individual countries to reduce their net emissions of GHGs is unlikely. This is because significant reduction of net GHGs emissions by a single major net emitter, say, for example the EU, is unlikely to substantially slow down the rate of increase in concentration in the atmosphere because the emissions of GHGs worldwide is increasing rapidly with spreading industrialization. On the other hand, unilateral changes in energy use patterns are widely perceived to have adverse effects on a country’s economic growth, consumer welfare and trade competitiveness. This perception is shared by both developing (DCs) and industrialized countries (INCs). Some major policy instruments have been assessed on the basis of experiments with the CGE model. The use of each of the policy instrument for direct GHGs regulation is promising. The results of the above experiments seem to show, that first, emission standards accomplish significant decreases in net GHGs emissions with negligible relative GDP and Welfare index changes and without major distributional impacts in the sense of relative changes in factor rewards. They seem to work through major reduction in coal and natural gas use and slight overall reduction in the use of petroleum. Second, auctioned tradeable permits also accomplish large decreases in net GHGs emissions, with, however a perceptible increase in the Welfare Index and significant distributional impacts in higher rewards to land owners and labor relative to capital owners. They appear to work primarily by expansion to the forest sector and associated increases offsets generation. Third, the use of a GHGs tax on positive net emissions of GHGs by industries accomplishes large reductions in net GHGs emissions with significant increase in GDP and the Welfare Index. The relative changes in factor rewards are also important and favor land owners over labor and capital owners. This instrument too appears to work primarily through considerable expansion of the forest sector and consequent increases offsets generation. Each of these instruments show sufficient promise as effective policy tools for GHGs reduction, that it would be advisable to conduct further research in each case. The choice between standards on the one hand, and market-based domestic regulatory instruments on the other, is not straightforward. These results need verification through further analysis.

Este estudio evaluó los determinantes de la elección de estrategias indígenas relacionadas con el clima por parte de pequeños agricultores en el norte de Ghana utilizando datos primarios obtenidos a través de discusiones de grupos focales comunitarios y encuestas de hogares, y sujetos al modelo de regresión Multinomial Logit. Los resultados empíricos revelan que la presencia de un mercado, el crédito informal de amigos y familiares, la ubicación del agricultor, la extensión de agricultor a agricultor, notar una disminución de las precipitaciones y notar un aumento de la temperatura influyen en la elección de las estrategias indígenas relacionadas con el clima. Por lo tanto, existe la necesidad de mejorar el acceso de los pequeños agricultores al mercado, los servicios de extensión agrícola y su conocimiento de los cambios en las precipitaciones y la temperatura. Cette étude a évalué les déterminants du choix des stratégies autochtones liées au climat par les petits exploitants agricoles du nord du Ghana à l'aide de données primaires obtenues lors de groupes de discussion communautaires et d'enquêtes auprès des ménages, et soumises au modèle de régression Multinomial Logit. Les résultats empiriques révèlent que la présence d'un marché, le crédit informel d'amis et de parents, l'emplacement de l'agriculteur, l'extension de l'agriculteur à l'agriculteur, la constatation d'une diminution des précipitations et d'une augmentation de la température influencent le choix des stratégies autochtones liées au climat. Il est donc nécessaire d'améliorer l'accès des petits agriculteurs au marché, aux services de vulgarisation agricole et leur sensibilisation aux changements de précipitations et de température. This study assessed the determinants of Choice of Indigenous Climate Related Strategies by Smallholder Farmers in Northern Ghana using primary data obtained through community focus group discussions and household survey, and subjected to the Multinomial Logit regression model. The empirical results reveal that presence of a market, informal credit from friends and relatives, location of farmer, farmer-to-farmer extension, noticing of a decrease in rainfall and noticing an increase in temperature influence the choice of indigenous climate related strategies. There is therefore the need to improve smallholder farmers' access to market, agricultural extension services and their awareness of changes in rainfall and temperature. قيمت هذه الدراسة محددات اختيار الاستراتيجيات المتعلقة بالمناخ للسكان الأصليين من قبل المزارعين أصحاب الحيازات الصغيرة في شمال غانا باستخدام البيانات الأولية التي تم الحصول عليها من خلال مناقشات مجموعات التركيز المجتمعية والمسح الأسري، وتخضع لنموذج انحدار اللوغاريتم متعدد الحدود. تكشف النتائج التجريبية أن وجود سوق، والائتمان غير الرسمي من الأصدقاء والأقارب، وموقع المزارع، والإرشاد من مزارع إلى مزارع، وملاحظة انخفاض في هطول الأمطار وملاحظة زيادة في درجة الحرارة يؤثر على اختيار الاستراتيجيات المتعلقة بالمناخ المحلي. لذلك هناك حاجة إلى تحسين وصول صغار المزارعين إلى الأسواق وخدمات الإرشاد الزراعي ووعيهم بالتغيرات في هطول الأمطار ودرجة الحرارة.

Higher education is incorporating Information and Communication Technology (ICT) at a fast rate for different purposes. Scientific papers include within the concept of Technology Enhanced Learning (TEL) the myriad applications of information and communication technology, e-resources, and pedagogical approaches to the development of education. TEL’s specific application to higher education is especially relevant for countries under rapid development for providing quick and sustainable access to quality education (UN sustainable development goal 4). This paper presents the research results of an online pedagogical experience in collaborative academic research for analyzing good practice in TEL-supported higher education development. The results are obtained through a pilot implementation providing curated data on TEL competency’s development of faculty skills and analysis of developing sustainable higher education degrees through TEL cooperation, for capacity building. Given the increased volume and complexity of the knowledge to be delivered, and the exponential growth of the need for skilled workers in emerging economies, online training is the most effective way of delivering a sustainable higher education. The results of the PETRA Erasmus+ capacity-building project provides evidence of a successful implementation of a TEL-supported methodology for collaborative faculty development focused on future online degrees built collaboratively and applied locally.

To effectively address the sustainability crises our planet faces, decision-makers at different levels of government worldwide will have to get a handle on three key challenges: learning from Global North and South initiatives in tandem, taking stock of social innovations alongside technological fixes, and nurturing grassroots sustainable development initiatives next to, or in place of, top-down corporate and government interventions. Current scientific literature and grant-making institutions have often reinforced the compartmentalized fashion in which we learn and draw policy lessons from North/South, social/technical, and bottom-up/top-down sustainability initiatives, including local food system innovations. The strategic levers for global sustainable development lying in-between are thus left out. This paper uses exploratory, multiple case study analysis to address this omission. By concurrently drawing lessons from grassroots innovations in Brazil, New York, and Senegal—three profoundly different socioeconomic and geographic contexts—we identify common pressure points that have enabled local communities to drive system-wide transformations toward climate adaptation, resilience, and sustainability in the agri-food system. The findings of this paper would be of value to scholars, government officials, and community groups engaged in agri-food systems sustainability and interested in the processes of change that have allowed budding innovations to stabilize and scale up.
