Circular economy is a kind of economic growth pattern that utilizes resource circularly with low consumption, low emission and high efficiency. Upon the basis of circular economy theory to study the construction of green supply chain, with applied case study method, it reached the conclusions that: 1) The circular economys development is a staged process, it needs to plan at industry level; 2) Circular economy involves the whole industrial chain of production layout; and 3) Government can promote the green supply chain management and construction of circular economy through sharing resources and infrastructure.

Tidal fats resources is an important resource in coastal areas of China, which shows a trend of dynamic growth. Ratonal development and efectve utlizaton of tdal fats resources can alleviate the contradicton between more people and less land in China, and is of great signifcance to the development of coastal economy and the protecton of ecological environment in China. Taking Yancheng Tidal Flats of Coastal Areas as an example, analyzes the present situaton of development and utlizaton and the existng problems at the present stage. Relying on the existng industrial foundaton, this paper puts forward the development and utlizaton model of strengthening the constructon of port-neighboring industry, towns and ecological leisure tourism on the basis of modern agriculture

Cities and nations worldwide are pledging to energy and carbon neutral objectives that imply a huge contribution from buildings. High-performance targets, either zero energy or zero carbon, are typically difficult to be reached by single buildings, but groups of properly-managed buildings might reach these ambitious goals. For this purpose we need tools and experiences to model, monitor, manage and optimize buildings and their neighborhood-level systems. The paper describes the activities pursued for the deployment of an advanced energy management system for a multi-carrier energy grid of an existing neighborhood in the area of Milan. The activities included: (i) development of a detailed monitoring plan, (ii) deployment of the monitoring plan, (iii) development of a virtual model of the neighborhood and simulation of the energy performance. Comparisons against early-stage energy monitoring data proved promising and the generation system showed high efficiency (EER equal to 5.84), to be further exploited.

A solar cooling system with an optimized air-cooled double-effect water/LiBr absorption machine is proposed as a sustainable alternative to meet cooling demands in dry hot climates. This system allows eliminating the cooling towers in those regions of the planet where water is scarce. This work analyses the environmental benefits of this air-cooled system, as well as its environmental foot-prints, compared to a solar water-cooled single effect. In this regard, a methodology has been applied to calculate the annual saving in water consumption produced in a case study: a hospital located in Almer?a, in South of Spain. Further-more, the reduction in energy consumption and CO2 emissions is also quantified since this machine can be driven by solar energy and with higher efficiency than those of single effect.

Tribals, as indigenous communities, have always been subject to neglect and marginalisation. The non-inclusive economic mobility is the enduring legacy of ethnic segregations and discriminations. In the development framework, their inclusion into the fast-urbanizing urban spaces is considerably an unexplored question. In this backdrop, the paper looks at tribals’ economic mobility in the urban spaces of Jharkhand through occupational classes. The paper is based on the 21-fold industrial classification provided in B-Series tables by Census of India, 2011. It uses a simple statistical method to analyse the occupational structure, sectoral participation and economic mobility. The paper portrays an assorted picture, inapt to the claim of an inclusive development model. The tribals have hardly been successful in catching the neo-liberal market-led economic opportunities, as the most developed urban centres are barely in tandem with the higher workforce participation in secondary and tertiary sectors; especially in the formal sectors. The other contrasting scenario is the least developed urban spaces have a higher level of tribal workforce participation in the tertiary sector than their most developed counterparts.
