“…In this context, data gathered by environmental authorities are still very poor and highly underestimated [12]. A general lack of data on waste management practices is seen at the global level, which affects the measurement of C&DW performances across various economies [17]. Data about C&DW flows requires special attention because this fraction is disposed both legally and illegally and frequently is not recorded as a separate waste stream, or is recorded incorrectly [18].…”

The paper performs a critical overview concerning the construction and demolition waste (C&DW) management issues in Romania. Five main stages related to C&DW management are highlighted such as: (i) illegal dumping on public lands; (ii) C&DW collection and disposal in urban landfills; (iii) C&DW treatment and reuse in civil constructions (roads, coating material for landfills); (iv) regional integrated waste management systems; (v) recycling of building materials (e.g., cement industry and recycled aggregates). The paper reveals the poor monitoring of C&DW flows across Romanian counties and the geographical dimension of this waste stream collected by waste operators. The paper examines the current challenges in Romania and it reveals the future prospects to provide a reliable transition towards sustainable C&DW management activities. The targeted route: waste fractions can be recycled and/or reused as building materials via integrated waste management systems, which enable a circular economy in urban and rural municipalities.

“…Yuan and colleagues focused on investigating the practices, challenges and strategies of CDW in China, especially in Hong Kong [ 6 , 7 , 8 ]. Tam and colleagues concentrated on comparing waste management performance in different countries as well as evaluating the environmental and economic benefit of waste measures and policies [ 9 , 10 , 11 , 12 ]. In addition to assessing the environmental sustainability of recycled aggregates [ 13 , 14 ], Poon and colleagues also analyzed the waste reduction potential of prefabrication [ 15 , 16 ].…”

In past decades, the massive generation of construction and demolition waste (CDW) was increasingly threatening the public environment and humanity health worldwide. A large amount of research has been devoted to the CDW from difference perspectives. However, few scholars have attempted to summarize and review the extant studies, especially in the managerial areas of CDW (MA-CDW). This paper fills this gap via a systematic and quantitative review in the CDW management field. Employing the scientometric analysis method, a total of 261 articles published from 2006 to 2018 were collected to construct the knowledge map and comprehensive framework for MA-CDW. Results show that the overall evolutionary trend of MA-CDW was from basic management concepts to internal and external challenges analysis, to organizational strategy and innovative management practices. The major MA-CDW knowledge domains were identified and summarized into four pillars, namely: (1) factor and challenge; (2) composition and quantification; (3) assessment and comparison; and (4) technology and method. Based on the trend, knowledge gaps and future research directions were found out and discussed. This study contributes to the existing MA-CDW knowledge by presenting a comprehensive knowledge framework. Furthermore, these findings can provide the researchers and practitioners with an in-depth understanding for the sustainable governance of CDW.

“…From global-to-regional-to-local settings, C & D depicts serious challenges affecting SES [23]. Global statistics show that C & D activities worth one million US$, generates 28 to 121 tons of wastes with variations observed among countries [24]. Waste generation stream in C & D activities extends to involving excavation and extraction of resources such as rock and soil, waste asphalt, concrete, bricks, timber and vegetation, plasterboard, asbestos and contaminated soil.…”

This paper analyzed and mapped the impact of built environment (BE) on socio-ecological services along Dar es Salaam metropolitan coastline. In the period of 1995-2016, burgeoning population exacerbated high rate of construction processes and activities. Such anthropic initiatives affect the benefits and values delivered by landscape wetlands, estuaries, beach areas, open space and greenery patches in Dar es Salaam coastline. Motivated to understanding socio-ecological impacts (SEIs) of BE along the coastline; the study applied focus group discussions (FGDs) method to identify SEIs, and their category as either positive or negative. Using analytical hierarchy process (AHP) generated weight to each SEIs; thereafter combined that weight with landuse landcover (LULC) change statistics of each of the 67 wards involved in the study. Mapping results of geographically weighted regression and inverse distance weighting (IDW) interpolation (ArcMap v10.3) displayed the variables relationship magnitudes and distribution in positive and negative SEIs for year 1995, 2005 and 2016. logical and social systems [4]. Such intertwining feedbacks results in complex systemic relationship, termed as socio-ecological system (SES) [5] [6] [7].Existence of human desire for improved economic and social services in SES are external stimuli to coastline resources utilization hence degradation of ecological system [5]. Studies [8] explain that coastline, also referred to as coastal zone, ranges from 60 to 200 kilometre inland and 50 m depth of ocean water system. In between exists highly fertile areas like continental shelf, estuaries and wetlands at both low and high tide periods [9]; these fertile characters are a reason for dominant human perturbation in such areas [10] [11]. While [12] justified the relationship of anthropogenic activities and coastal zone, little has done to disclose the existing link of BE and its impact on SES.BE as a product of construction activities [13], in the search for suitable and comfortable places for recreation, residence and work; impacts the landscape by aggravating vegetation cover clearance, waste generation and permanent consumption of a piece of land [14] [15]. The habitat loss and fragmentation caused by such impacts account significantly for biodiversity loss. According to [16], the functioning of biodiversity species are greatly the determinant of the quality and quantity of services derived from SES. Thus, state of landscape loss or gain of such biological component is a socio-ecological impact (SEI) that alters SES functioning capacity [17]. Scholars such as [18] and [19] typify that some of the positive SEIs include cooling, shadow, air filtration, climate variability and flood prevention by trees; pollinations by avian and arthropods species as well as medicines and food from both fauna and flora.However, irreversible anthropic construction activities provoke landscape environmental challenges as result of megacities development processes and activities [20] [21]. In the search for quality prod...
