The circular economy (CE) model promotes the production of goods and services in a sustainable way, optimizing the consumption of natural resources and mitigating the wastes. In the last years, this model has received a lot of attention and support at the governments' level, internationally; also, in Latin America. Cuba pleads for a sustainable development, with political and incentives for the recycling, the use of the renewable sources and the energy efficiency, as impeller motor of its economic model. Hence, Cuban universities have been requested to include this topic in their study plans, for all the careers. The objective of this paper is to describe how the topic of Circular Economy has been incorporated in the Study Plan of the Electrical Engineering Career at the Technological University of Havana "José A. Echeverría "CUJAE and the results, during the implementation in the 2021 academic year. [ABSTRACT FROM AUTHOR]

Objective: o reflect about the importance of the supportability of agroproductive systems and of their contribution to local development in Cuba, from an economic, ecological and sociocultural approach. Materials and Methods: This study, of exploratory, analytical and descriptive type, is based on the bibliographic review of the concepts sustainable and supportable systems, bioeconomy, agroecology and development programs in local contexts. For such purpose, different information sources, scientific papers published about the topic and literature produced by national and international organisms, were consulted and analyzed, in order to know about the state-of-the-art of the object of study and to concrete necessary definitions and strategies for the implementation of supportable systems in the framework of agricultural programs. Results: It was corroborated that supportability is a way of living and producing in harmony with the environment, to guarantee that future generations can satisfy their needs. From its multifunctionality, supportability can be a tool in supportable local development, from the commitment to agrifood models based on agroecology, bioeconomy and food sovereignty. Conclusions: In Cuba it would be pertinent to establish local strategies to improve people's quality of life and preserve the environment, from an agroecological and supportable approach.

This paper presents the project «Measures to improve the management of local development of villages, towns, and municipalities located in the province of Cienfuegos», conceived at the University of Cienfuegos as part of the National Program for Local Development. It suggests a methodology combining futures studies and statistical tools for assessing key variables through their indicators according to economic, social, and environmental aspects of sustainable development. This methodology was used in the Guamuhaya Mountains (Cienfuegos), and can be also used in other Cuban mountain ecosystems. Such methods as expert evaluation, structural analysis, and statistical modeling were used to identify and assess 10 key factors, 37 indicators, and 16 key variables which can be also used in other studies of these Mountains in tune with the 2030 Agenda for Sustainable Development and Sustainable Development Goals.

From a Third World vision, the present paper deals with some international methods to evaluate sustainability in Projects and realizations, at architectural and urban scale, in order to, valuate in a comparative way, strengths and weakness, mainly taking into account their possible application in developing countries, and particularly in Cuba. The research started by looking for a method to evaluate sustainability in the University of Informatics Sciences, and it was later on extended with the inclusion of the African experience. The evaluative categories differ from one system to the other, but all of them emphasize the environmental dimension of sustainability. Only two methods coming from developing countries include social dimension and the necessity of an endogenous approach, which is an important current challenge for Latin America.

In the knowledge society and information sciences face new social challenges, including the need for a more humanistic vision committed to its current context, going beyond the traditional academic and research processes. In the Cuban revolutionary practice, authentic source where theory is enriched, speaking of an update of the economic model, but no debate on political economy, nor taken into account in the analyzes. However, it is argued that positive outcomes are expected from the ideology where the economy is the locomotive and guide that process. This paper is an approach to the problem and the exposure of a number of elements that must be taken into account when talking about teaching and research of political economy and social science and its place in the construction of a prosperous socialism and sustainable.

This text discusses sustainability in architecture and its relation to vernacular building techniques, i. e., how adaptation and invention marked the creation of some of the first places of worship of the Chilean evangelical church. An analytical method was adopted for the study of how the temples were designed and built, and a mixed inductive-deductive method was employed for the identification of key practices that made possible low-power consumption and a minimal impact on the environment. Two main practices were identified. The first one consists in the reuse of buildings, structures, materials, furniture and typologies (adaptation). The second practice involves the creation ex nihilo of solutions for load-bearing structures, construction details and modes of financing (invention). Having demonstrated the sustainable qualities of the temples' construction, in the early twentieth century, and with the certainty that such techniques are perfectly feasible today, this paper concludes that the impediment to sustainable construction today is ethical -- not technical.

Despite the actions toward a more sustainable development, a poor understanding of the role of architecture and urban design to achieve this goal is appreciated in Cuba. The objective of this paper is to show how it is possible to improve the sustainability in a built environment, by simple and economic transformations, taking as study object the Universidad de Ciencias Informáticas (UCI). A qualitative urban diagnosis was carried out in order to define the main performance strategies. The proposals are progressive, based on minimum intervention and maximum impact. Some of them are: rezoning to reduce distances, using alternative transportation means as bicycles and zero energy minibuses, incorporating new services, using renewable sources of energy and creating an ecological park with a wetland for the gray water treatment. This diagnosis allowed to select the more problematic buildings to be transformed based on a qualitative and quantitative evaluation. [ABSTRACT FROM AUTHOR]

The objective of this paper is to develop an Environmental Management Strategy that is intended to reduce the environmental impacts in the Naranjo river drainage basin. In order to reach this objective, a diagnosis was done, that consisted in the literature review on the topic as well as the realization of participatory workshops involving different techniques, tools and methods, such as brainstorming, SWOT matrix, DPSIR framework and experts' approach, for identifying the main environmental problems that affect the basin. A geographic information system (GIS) was designed for managing natural resources in the basin. Results show that the main environmental problems are: soil degradation, ,deforestation (loss or lack of hidroregulatory fringes on river and reservoir beds), Deterioration of sanitary-hygienic conditions in human settlements, groundwater and air pollution were maily caused by the inadequate land-use planning, which, along with the population's lack of environmental education, not only contributes to maintaining the environmental impact, but also to increasing it, and can lead to irreversible damages. As part of the strategy, a series of agreed actions was planned to diminish the environmental problems in the basin, where the social actors take part actively in managing those problems, and favor the decision making process which focus on sustainable development.

Taking as much advantage as possible of the urban land is a basic principle for the sustainable development of the built environment. It depends on the urban model and also, on the architectural typologies, but the main conditioning factor relating these two scales is the relationship between indoors and outdoors in order to achieve appropriate environmental conditions in interior spaces. On the other hand, housing building typologies are decisive in land use and densities. The paper presents a methodological approach for urban models and architectural typologies (housing buildings) evaluation, taking into account parameters and indicators of their quality and economy, where land use and indoors environment are the main and contradictory variables studied. The results permitted to establish urban planning and architectural design indicator to get an appropriate use of the urban land, ensuring at the same time, adequate environmental conditions in housing interior spaces.

Third millennium begins in a globalized world: 6.3 thousand million people, 850 millions hungry, 1,200 without drinkable water, 2,400 without proper healthcare, 850 millions illiterate, 10 million children die annually. Meanwhile, 10% of the population enjoys 70% of wealth. Social explosions, wars, hurricanes, earthquakes, environmental contamination, floods, global heating, AIDS, proliferate. Rural communities have economic and socially collapsed, unemployment increases for technologies of low labor force, migration to the cities persists. The "Green Revolution", of specialized and industrialized agriculture of developed countries has generated environmental conflicts and has not been any solution. The geophagy and power thirst of countries and political leaders, generate more unbalanced distribution of wealth. In our planet, positive results with agroecological systems of production are plentiful, demonstrating its possibility to solve great number of problems. In Latin America and Cuba, large number of experiences based on knowledge of rural and indigenous traditions, research and commercial production exist, with feasible solutions for this called third world", where the neediest countries are. There are possible roads to reach the desired agricultural development. This paper summarizes some examples of these advances. The future challenge is to integrate agroecosystems components to achieve synergies, consolidating holistic agroecological systems, with biological, productive, economic, energetics and environmental efficiency. It is hopefull to think in an agroecological future together to political will for the economic and social development, can contribute in a high degree to liberate our third world countries of the critical current situation.
