    The impact of construction of hill roads on the environment, assessed using the multi-criteria approach
    (Taylor & Francis, 2021-03-30) Singhal, Anupam; Singh, Ajit Pratap; Mittal, Ravi Kant
    The environmental impact assessment (EIA) in regard to road widening of a 26 km stretch in Reasi District of Jammu and Kashmir (Union Territory) has been studied. Impact on the environment included temperature, deforestation, rainfall, landslides, blasting, surface and groundwater, air and soil pollution, habitat change, historical and socio-environmental factors. The study indicates that buses are the highest emitters of Hartridge Smoke Unit (HSU) followed by light commercial vehicles, heavy commercial trucks and cars, and three-wheelers in that order. The study also established that the make and age of the vehicle had negligible impact on the observed values of HSU and the light absorption coefficient (k). With the help of multi-criteria tools, the EIA has been quantified for four alternatives of a road stretch using fourteen criteria. The results show that the impact of the construction of two-lane highways on the environment is high, but that it can also be mitigated effectively.

    Urban Policymaking for a Developing City Using a Hybridized Technique Based on SWOT, AHP, and GIS
    (ASCE, 2021-06) Singhal, Anupam; Routroy, Srikanta
    The high rate of population growth in the 21st century is causing mass migration from rural to urban settlements. Rapid urbanization in developing countries generally follows unregulated growths, urban sprawls, and inefficiencies in city planning. With the trend of rapid growth in developing countries, it has been very difficult to maintain an environmentally sustainable and socially resilient policy framework. This study proposes an urban development policy framework for sustainable planning in developing cities by coupling geographic information system (GIS) geospatial zonal analysis with strength, weakness, opportunities, and threats (SWOT) and analytical hierarchy process (AHP) model. The hybridized approach incorporates critical issues such as disaster impact, slum settlements, infrastructure deficit, and noise pollution in urban planning. A case study of the city of Delhi was taken to demonstrate the applicability of the proposed framework in developing cities. The novelty of the study is that it proposes a highly flexible urban development plan based on the integrated GIS and SWOT-AHP methodology that is specific to the needs of developing economies and developing cities. The methodology also puts a strong emphasis on disaster prevention and response in the urban development plan. Results from the GIS–SWOT-AHP model can be used for region-based urban planning that prioritizes regions needing critical attention and directs the development of the city toward a sustainable future.
