Vulnerability assessment of the Satluj catchment for sustainable development of hydroelectric projects in the northwestern Himalaya

Hydropower if scientifically developed is considered to be one of the clean and non-polluted renewable energy sources.But its impacts always exist on physical and social environment of the area.The present study was conducted in the River Satluj basin which is well known for its hydropower potential.The main objective of the study was to understand the vulnerability of the Satluj basin and to develop a strategy for the development of hydropower projects.This basin has been facing many problems relating to construction of haphazard development of hydropower projects.This has led multi-hazards like landslides,floods,earthquakes,etc.Here,vulnerability assessment index was assessed quantitatively and qualitatively.Geographical Information System and people’s perception were used to study these aspects in the basin.The parameters considered for vulnerability assessment were slope,slope profile,relative relief,curvature,slope aspect,soil texture,lithology,river morphometry,precipitation,hydroelectric projects,land use and land cover,mass-movement,flood,geological elements and earthquake occurrences.The highest vulnerability was found in the middle zone,and finally on the basis of parameters analyzed;the hydropower’s development strategy was developed.

Sustainability Index： An Application into Sustainable Engineering Infrastructure Management and Assessment

A proper infrastructure assessment in the contemporary engineering world has become very crucial due to the palpable resources challenges. Therefore, from the design, construction, operation and maintenance stages of the built infrastructural systems; cognizance must be taken of the associated factors and their significance. In considering these indices, the experts will save lots of resources wastage thereby integrating new technologies into the full life cycle of the infrastructure. In this paper, two sets of building infrastructure professionals were assessed. These are the corporate building organization （CBO） and the Operators from two shopping malls within the UK. Thirty-four factors regarding the sustainable building infrastructure appraisal were identified through literature reviews. These characteristics were accordingly classified into two factors （group I and II） and a comparative analysis of their influence conducted. Priority rating of the factors assessment on building infrastructure was through structured, administered survey amongst professionals within these organizations. Information of this survey revealed that the experts maintained a strong concordance in rating these factors. As a result, the associated factors have relatively substantial degree of influence in this context. Further indications of the result in groups I and II are that the CBO experts have indicated the infrastructure size, planning and design as the key factors. Also, the type of building characteristic was among others as the top and bottom marked cases. Similarly, the Operators too have maintained that a proper infrastructure design should incorporate a good policy framework for efficient energy saving fixtures and conservation. Additionally, the installation of quality equipment promotes cost savings of the resources and a just-in-time maintenance of the infrastructure at large. The maintain as-we-go philosophy characteristic was not strongly encouraged in this case.

SUSTAINABLE NITROGEN MANAGEMENT INDEX: DEFINITION, GLOBAL ASSESSMENT AND POTENTIAL IMPROVEMENTS

To represent the sustainability of nitrogen management in the Sustainable Development Goals indicator framework,this paper proposes a sustainable nitrogen management index(SNMI).This index combines the performance in N crop yield and N use efficiency(NUE),thereby accounting for the need for both food production and environmental protection.Applying SNMI to countries around the world,the results showed improvement in the overall sustainability of crop N management over the past four decades,but this improvement has been mainly achieved by crop yield increase,while global NUE has improved only slightly.SNMI values vary largely among countries,and this variation has increased since the 1970s,implying different levels of success,even failure,in improving N management for countries around the world.In the standard SNMI assessment,the reference NUE was defined as 1.0(considered an ideal NUE)and the reference yield was defined as 90 kg·ha^(−1)·yr^(−1) N(considering a globally averaged yield target for meeting food demand in 2050).A sensitivity test that replaced the reference NUE of 1.0 with more realistic NUE targets of 0.8 or 0.9 showed overall reduction in SNMI values(i.e.,improved performance),but little change in the ranking among countries.In another test that replaced the universal reference yield with region-specific attainable yield,SNMI values declined(i.e.,improved performance)for most countries in Africa and West Asia,whereas they increased for many countries in Europe and South America.The index can be improved by further investigation of approaches for setting region-specific yield targets and high-quality data on crop yield potentials.Overall,SNMI offers promise for a simple and transparent approach to assess progress of countries toward sustainable N management with a single indicator.

An Analysis of the Benfit on Green Risk in Construction Projects

The Construction project green risks (CPGRs) refer to those threats to environment, energy sources and material re-sources during the entire life-cycle of a construction project. The emergent green risks in exploiting these resources are of varying concern to all. In this paper, evolutionary game is introduced to make about impacts of strategy choices from interactions among the choices developers, and between the choices developers and EPDs on project green risk. The results show that CPGRs will occur if either developers find that not managing CPGRs has a better payoff than opting for CPGR management, or if monitors impose only mild fines even when they find CPGRs within construction projects of developer’s firms. The study also shows that there is a prohibitively expensive cost incurred by EPDs in monitoring CPGRs. Finally, some strategies are given for EPDs to help them make policies to regulate the strategies of developers.

Stormwater Management Practices and Green-Blue Infrastructure in Urban Areas: an Overview

Water quality,flooding risk,and water consumption in urban areas are emerging issues.Urban impervious surfaces increase stormwater runoff,affecting ecosystems and leading to hydrogeological instability and flooding risk.Sustainable urban design strategies can contribute to counteract the negative impact of anthropic activities both at city-scale and global scale.Green and Blue Infrastructure(GBI)approaches,in particular,are an alternative to stormwater traditional management.In Europe,Sustainable Drainage System implementation copes with impervious surfaces to achieve water quality,amenity,and biodiversity increase.Best Management Practices,developed mainly in the USA,focus on specific measures for sustainable stormwater treatment.Water Sensitive Urban Design,spread in Australia and England,also aims to minimise the impact of developed areas preventing flood risk,limiting water consumption and enhancing environmental quality.In the USA and Canada,Low Impact Development offers design strategies to manage runoff and deliver structural practices to mimic predevelopment processes of infiltration,filtration and detention.

Green Barriers： Obstacle or Stimulation ？

Most viewpoints in China consider green barrier is one kind of non-tariff barriers imposed by developed countries and is unfair to developing countries. Different from these, this paper points out that green barriers, evolving from the background of sustainable development theory and the principle of environment protection, have positive effect on ideology, international institutional arrangement and innovation stimulation. Demonstrating the rationality of green barriers, the paper puts forward that green barriers should be regarded as the stimulation for technology innovation and industrial restructure rather than obstacles. The best way to surmount the green barriers for Chinese government and enterprises is to implement circular economy and clean production so as to achieve the harmony of trade, environment and economic development.

COMMUNICATION TURNS GREEN CONSTRUCTION PLANNING INTO REALITY

Green planning is critically important during the design phases of construction projects but continually gets less attention during construction.Project owners and planners need to understand how communication influences green implementation.To address a gap in the extant research,this paper presents the evaluation results on how sustainability awareness of field supervision personnel impacts the successful completion of school projects by proving that communicating sustainability goals with them is vital for decision-making during the construction stage of the project.This paper uses data collected from 162 new school construction projects to compare sustainability design goals with their successful incorporation into completed projects.Seventy-one project managers and inspectors were surveyed to assess their awareness of key high-performance sustainability requirements that were built into the designs.The responses from these two groups were compared to examine the positive or negative impacts.The analysis results show that early and continuous communication of sustainability design goals with field supervision personnel has a significant impact on whether those goals are realized when the project is turned over to the owner for occupancy.Successful implementation of sustainability goals not only provides economic benefits from fully exploiting life-cycle costs,but also holds the promise of providing a healthier working environment.

DESIGNING FOR ENVIRONMENTAL AND INFRASTRUCTURE SUSTAINABILITY: ONTARIO CASE STUDIES FOR RETROFITS AND NEW DEVELOPMENTS

The Low Impact Development (LID) approach has been implemented worldwide for managing stormwater quantity and quality within the context of land development, re-development, and retrofits within an existing development site. Since the inception of the concept in the 1990s, the application of LID has covered different land uses, spatial scales, and environmental objectives, leading to an expanded vision for applying and testing the LID approach. Recently, holistic methodologies and frameworks have linked land planning to key ecological landscapes larger than the previous site scale practice. This new emerging paradigm considers the watershed, subwatershed, and neighbourhood, in addition to the site scale, and consequently, recommends a landscape-based LID and broader Green Infrastructure (GI) solutions (Benedict and McMahon, 2002;Tzoulas et al, 2007;NRDC, 2011). As part of the holistic understanding of land planning and environmental features and functions within the intended spatial scale, LID and GI measures have been designed and constructed as retrofit measures (i.e., measures implemented within existing development) and as measures implemented within new development areas. Under this new paradigm, the land planning context is linked to environmental objectives to provide end points for environmental conservation and restoration within an ecological landscape such as watersheds, subwatersheds, and stream corridors. This paper presents three case studies for the design and construction of LID and GI measures within different land use contexts and for providing multiple environmental objectives.
