High-tech greenhouses and artificial light applications aim to improve food production, in line with one of the sustainable development goals of the UN Agenda 2030, namely, “zero hunger”. In the past, the incandescent lamps have been used for supplementary lighting (SL) at higher latitudes to increase greenhouse production during the dark season. Light-emitting diodes (LED) have been replacing gas discharge and incandescent lamps, and their development is expanding SL applications in different agricultural scenarios (e.g., urban farming, middle latitudes). In fact, recent research on LED applications in Mediterranean greenhouses have produced encouraging results. Since middle latitudes have a higher daily light integral (DLI) than higher latitudes in the dark season and climate conditions influence the installed power load of greenhouses, LED installation and management in Mediterranean greenhouses should be different and less expensive in terms of investment and energy consumption. Accordingly, the aim of this review is to outline the state of the art in LED applications and development, with a focus on latitude-related requirements. Tomato was used as a representative crop.

The Sustainable Development Goals (SDGs) - No poverty, Zero Hunger, Good Health and Quality Education are directly linked to the world agriculture which constitute to about 6% world's GDP. However, the changing climate conditions are making tough for the farming and the food production is being effected. To eradicate poverty and to have no person goes to bed hungry, food must be adequate in household level, citizens should be provided with quality & safe food. For building healthy people and providing quality education all are linked with the agriculture. To address this situation, globally, researchers are working for hard and generating solutions for adaptive, resilient and sustainable farming livelihoods

The paper outlines major preconditions of development of energy efficiency programs and the process of their introduction from the perspective of sustainable development concept. Energy saving measures of European Union are examined, its experience and results, like green books and Thermie programs, etc are analyzed. The paper also specifies relevant activities and responsibilities undertaken by Member States by 2030 and the rates planned to be achieved. The experience of neighboring Poland in energy efficiency promotion is analyzed, as far as the country most closely resembles Ukraine by the initial rates in 1990. We calculated conditional losses of Ukraine in 2017 as the gap between the rates of energy efficiency of Ukraine and Poland (similarity of climate conditions and the state of housing funds allowed us to assume that the comparison will be the most correct regarding Ukraine). The results of calculations make us conclude that the funds are used most efficiently if the money designated, for example, for subsidizing of population are directed at strengthening of energy efficiency (at least up to the level of neighboring country). It will result in saving of about 40 billion. This is the amount defined as Ukrainian capacity in terms of improvement of energy saving and possible results of its realization. The paper determines the stage Ukraine is at in introduction of energy efficiency measures and programs: “warm loans” program; conditions regarding energy saving in Ukraine enshrined in the EU-Ukraine Association Agreement; creation of legal basis, namely the Law of Ukraine “On Energy Efficiency Fund” as of 8 June 2017. The role of newly created Energy Efficiency Fund is analyzed. Special attention is paid to the fact that energy efficient construction is one of international liabilities undertaken by Ukraine. The presence of The Active House Alliance at Ukrainian market is an important achievement in this sphere as it is the non-profit association aiming at creation of housing concept corresponding to the sustainable development principles.

The building sector is one of the most relevant at world level in view of the percentage of gross domestic product (GDP) concerned, as well as the number of new jobs created. Nevertheless, it is a completely male-dominated industry. Different institutions and organisms, such as the Agenda 2030 and the Sustainable Development Goals, struggle to reduce gender inequality in different environments, including the working one. Aligned with these goals, this study provides the data exploited from the first survey regarding gender inequality within the professionals of the building engineering field in the Spanish population as a whole. This survey was developed in 2018 by the Spanish General Council of Technical Architecture and it was sent to its members. The sample involved 1353 cases. For this data mining, bivariate analyses were conducted in order to subsequently carry out a factor analysis and the socio–demographic composition of the dimensions found. Results exposed statistically meaningful differences in the eyes of women and men about those factors which facilitate practice and continuity in the profession. The most relevant conclusions drawn from the factor analysis reflect the existence of three factors: (1) work competences, (2) social capital and (3) physical appearance and being a man, dimensions in which women and men’s opinion was unevenly distributed.

The United Nations Agenda 2030 contains 17 sustainable development goals (SDGs). These goals are formulated in anthropocentric terms, meaning that they are to be achieved for the sake of humans. As such, the SDGs are neglecting the interests and welfare of non-human animals. Our aim in this paper was to ethically evaluate the assumptions that underlie the current anthropocentric stance of the SDGs. We argue that there are no good reasons to uphold these assumptions, and that the SDGs should therefore be reconsidered so that they take non-human animals into direct consideration. This has some interesting implications for how we should understand and fulfil the pursuit of sustainability in general. Most noticeably, several SDGs—such as those regarding zero hunger (SDG 2), good health and wellbeing (SDG 3), clean water and sanitation (SDG 6)—should be achieved for animals as well. Moreover, the measures we undertake in order to achieve the SDGs for humans must also take into direct account their effects on non-human animals.

The transformation in education must be directed in accordance with Sustainable Development Goals (SDGs) program. This article aimed to discuss the potential support of New Biology in achieving the formulated SDGs. This literature review covered 31 articles which were published since 2010 to 2019. The keywords used to collect the data were new biology, future biology, biology education, biological science, and biology. The review results informed that New Biology can potentially enact five goals of SDGs, i.e. goal 2 (Zero Hunger), goal 3 (Good Health and Well-being), goal 4 (Quality Education), goal 6 (Clean Water and Sanitation), and goal 7 (Affordable and Clean Energy). By considering the findings, it is suggested to promote New Biology approach in Indonesian educational system.


The purpose of the article is to consider the theoretical foundations, applied aspects, concepts and goals of sustainable development, as well as the study of factors and threats to the sustainable development of Pridnestrovie. Main material. The authors conducted a brief analysis of the main stages of introducing the conceptual apparatus used to assess the degree of world stability as a whole, regions and countries. Various approaches to defining the essence of sustainable development are considered. The author gives an extended interpretation of the "sustainable development" concept, which assumes that it is determined not only by environmental and economic aspects, but also has political, military, informational and other components. Groups and particular examples of indicators that characterize the degree of sustainable development are given. A list of factors that directly or indirectly affect the sustainability of countries and regions has been compiled and analyzed. Hierarchical levels of research on sustainable development issues are highlighted. Emphasis is placed on the study of the features of ensuring sustainable development of regions. Didactic aspects of studying the problems and mechanisms of ensuring sustainable development in educational institutions of different hierarchical levels are also considered. The applied aspects reflected in the article include assessment and analysis of a number of indicators reflecting development sustainability of the Transnistrian region of post-Soviet Moldova. Retrospective, modern and long-term threats to the sustainable development of the Transnistrian region are identified. Conclusions and further research. Some tools (measures) to ensure long-term sustainable development in the context of globalization and high turbulence of the international environment are proposed. Tools aimed at increasing the sustainability of the territorial units’ development of Pridnestrovie, the following are proposed: - diversification and growth of industrialization of economic systems; - preferential support for the development of high-tech material and energy-saving industries; - differentiation minimization of financial and property stratification of the population; - implementation of environmental standards and environmental management (ISO 14000) in industrial enterprises.

Promoting supply-side structural reform is the key to China’s economic transformation and upgrading. As disruptive innovation is affecting different sectors and areas of society, numerous high-tech development zones should fully release their vitality and realize unprecedented development while contributing to this reform. This study attempted to further analyze the Research and Development (R&D) efficiency of high-tech zones in the past mode, and shed light on a more advanced and effective development pattern in the near future. This paper used Data Envelopment Analysis (DEA) model, which is a linear programming method to measure the efficiency between multiple decision-making units, and categorized three decisive factors to reach solid conclusions [1]. Our statistical results indicated that the low R&D efficiency is ubiquity among high-tech industries, and there is not yet a strong platform for advanced R&D activities. Lastly, this paper suggested strategies to maintain the sustainable development of the high-tech industry under the supply-side reform.


The chapter argues that inequality between men and women has led to the gap in income and poverty for women. Gender inequality and women's empowerment have, therefore, become one of the 17 pillars of the Sustainable Development Goals Agenda 2030. This chapter, therefore, examines the global performances on gender inequality index (GII) and the Sustainable Development Goals Agenda 2030, regional performance and the Sustainable Development Goals, the top best performers on gender gap parity versus the worst performers on gender gap parity, and sub-national performances and global rankings. Also, this chapter examines the challenges of achieving gender equality by 2030 along with policy options for achieving gender equality in the year 2030.
