AbstractInnovation in construction is presented as a necessary aspect in the answer that the construction industry must provide to solve its negative impact on the environment. Original and innovative research is only part of the work to be accomplished. More important is the implementation of innovation in practice, where traditions are strongly rooted in society, and safety and long term reliability are required. Lessons from nature and study of durable examples handed down from the pasts serve as guidelines to innovative approaches that contribute to sustainability.

The article provides an analysis of construction influence on the environment, the environment-forming function of the construction activity has also been studied. The assessment of environmental factors has been made on the basis of interdisciplinary approach. The conducted assessment of state and dynamics of eco-economic interaction between the construction activity and the environment, the basis of sustenance of the urban and agricultural economy in Russia, has demonstrated the investment potential of production of the construction materials. However, the raw materials are mined by the open pit; the lands of agricultural purpose get requisitioned for the pits. All this shows an ecological inefficiency of the construction industry growing from year to year. A direct demolition of natural eco-systems in the local areas contradicts the attractiveness of ecological construction in the framework of movement to the sustainable development of the country. The system “construction – vital activities environment” has been reviewed as an eco-economic equilibrium, as a criterion of the authentic system-level development. It is necessary to increase the quality of ecological monitoring. The performed analytical helps to come to a conclusion that notwithstanding the developed basic provisions of institutional policy a negative impact of construction on the environment impedes the development of ecologically-oriented investment and construction activity and sustainable development of the country.

The Impact

Concrete has been used in the construction industry since long times. It is probably the most widely used construction material in the world, largely due to the abundance of the raw materials for cement manufacture, low relative cost and the versatility and adaptability of concrete in forming various structural shapes. Massive production of concrete and the associated substantial manufacture of cement have however been observed to have a very negative impact. One of the biggest issues of growing concern at the moment faced by concrete industries is the impact of cement production on the environment. The production of cement not only depletes significant amount of natural resources, but also liberates a considerable amount of carbon dioxide (CO2) and other greenhouse gases into the atmosphere as a result of decarbonation of limestone and the combustion of fossil fuels. In addition, cement is among the most energy intensive construction materials, after aluminium and steel [1].

Abstract: Construction activity in India has magnified well within the past decade. Likewise, there has conjointly been a proportion to rise within the generation of construction and demolition waste (C&DW). This, alongside the fact that in India the speed of recycling and reuse of C&DW continues to be quite low and has engendered a heavy environmental downside and a motivation to develop ways and management plans to resolve it. Almost every time the construction and demolition waste end up settling in landfills disrupting the environmental, economic, and social life cycle. Its composition has a significant potential to reuse or recycle C&DW, and thereby, contribute to enhancing the sustainability of construction, however, practical procedures don’t seem to be widely known or practiced within the construction industry. Elements of construction and demolition waste generally embrace concrete, asphalt, wood, metals, roofing, paper, plastic, drywall, and glass. Sustainable development defines as accomplishing the current requirements without compromising the ability of future generations to satisfy their own needs and can be thought of as one of the concrete solutions to resolve construction and demolition waste downside. Sustainable development in construction can facilitate plenty to cut back the issues associated with the environment and natural resources as the construction industry is among the major user of the world’s resources. Sustainable design, correct use, and reuse of the resources/construction materials can create the construction industry a lot more economical and greener. There’s conjointly a large demand for natural aggregates within the construction sector with a big gap in its demand and supply, which may even be reduced marginally by the employment of recycling and reuse of construction and demolition waste. Correct handling, storage, and treatment of C&D waste not only solely forestall degradation of Mother Earth but even have an important impact on sustainability using reducing the usage of natural resources. The paper covers various issues associated with the reusing and recycling of C&D waste, which needs restrictive mechanisms and procedures to be followed for achieving the aim of sustainability in the construction industry.

Participatory Observation

The notion of ‘ownership’ has occupied a central place in measuring the effectiveness of North–South cooperation. How is it represented in South–South cooperation (SSC) and how does it affect the effectiveness of SSC? There is no clear answer in the existing literature. In this article, we describe the representation of ‘ownership’ in SSC and explain how it has affected the process and impact of SSC projects using case studies of three uniformly designed Chinese agricultural aid projects in Mozambique, Tanzania, and Ethiopia. Based on long-term participatory observation and in-depth interviews, we find that ‘ownership’ in SSC is represented differently from project design to implementation. Divergence and ambiguity exist among different stakeholders on the operation of ‘ownership’. ‘Co-ownership’ of two partners at the local level contributes to the effectiveness of SSC projects while ‘de-ownership’ and ‘forced ownership’ have a negative impact on the survival and sustainable development of SSC projects.

The Impact

This study examines the impact trade openness has on sustainable development in Saudi Arabia. It does so by employing the autoregressive distributed lag cointegration framework, using annual data over the period 1971 to 2016. Overall, the findings suggest the existence of a long-term relationship between trade openness and two indicators of sustainable development—are economic growth and environmental quality. Results indicate that trade openness does not affect both indicators of economic growth and environmental quality in the short-term. However, in the long-term, trade openness has a significant negative impact on economic growth when it is proxied by the variables the ratio of exports plus imports to GDP, and the ratio of exports to GDP; but a significant positive impact for the variable the ratio of imports to GDP. In addition, trade openness negatively affects environmental quality in the long-term. The tests used for diagnosing models show that they are valid, and thus, our findings are robust. Comprehensively, we find that trade openness could have led to the degradation of sustainable development in Saudi Arabia for the past fourteen years.
