  • Sustainable strategies for water management challenges in hill-towns

    • Free pre-print version: Loading...

      Authors: Sandeep Sharma, Mahua Mukherjee, Deepak Khare
      Pages: 89 - 107
      Abstract: Water is the most precious resource on Earth for survival, which is limited. Cities have grown rapidly in recent decades. Besides population, this growth includes additional basic infrastructures like buildings, roads, waste, and emissions. Increased urbanisation and built-up infrastructure result in increased runoff due to impermeable surfaces and limited recharging of groundwater, thus causing water scarcity and intensifying water problems in cities, including hill-towns. In hill-towns, topography plays a major role in the distribution network of water supply and wastewater management. This study focuses on challenges of water management in the hill towns in general. The research is divided into two stages. Stage I focuses on the challenges regarding water management in hill-towns, and stage II deals with the scope of improvising the water management supported by the literature at the city-level. The paper concludes by suggesting a few possible solutions for sustainable water management to resolve the problems associated with hill-towns.

  • Exploring the certainty of reciprocal relationship with outcome
           expectations in water conservation efforts among generation Y: social
           cognitive theory approach

      Abstract: Water conservation among each individual is a crucial factor for better living standard. Attitude and emotional factors with social cognitive behaviour will play an essential role for present and future generations. This empirical study was conducted in relation to generation Y in Kuala Lumpur metropolitan city, Malaysia. A sample size of 265 generation Y population was used with convenience sampling method in identifying their attitude and behaviour. The finding revealed that generation Y outcome expectancy has significant positive effect on water conservation. The outcome expectancy was predicted by environmental factors, personal factors and perceived self-efficacy. According to the model evaluation, the adjusted R<SUP align="right">2</SUP> was 0.78, which explains almost 78% of the variance in outcome expectancy in determining behaviour in water conservation among generation Y. In reciprocal identifications the variables were tested with correlation and all variables achieved positive strong correlation.

  • Quantitative assessment of climate change impacts on the spatial
           characteristics of drought hazard in arid and semi-arid regions of Iran

      Abstract: In the present study the standard index annual precipitation (SIAP) and the drought hazard index (DHI) are used to investigate the frequency as well as the spatial extent of meteorological drought hazard in arid and semi-arid regions of Iran for the historical (1985-2010) and future (2011-2040, 2041-2070 and 2071-2100) periods under different RCP scenarios (RCP2.6, RCP4.5 and RCP8.5). Results indicate that, for the historical period, the most severe droughts have occurred in 2001, 2008, and 2010 (62.84, 43.93 and 45.73% of the study area). Furthermore, under the RCP8.5 scenario, the frequency of severe droughts would significantly increase and the most severe cases would occur in 2040s (almost in entire region). In addition, drought hazard assessment shows that, by the 2071-2100 period, except for the Southeastern parts, other regions would be identified as 'very-high-hazard' zone. These changes are important because they would negatively affect water resource management in arid and semi-arid regions of Iran.

      Authors: Raseswari Pradhan, Jaya Prakash Sahoo
      Pages: 141 - 166
      Abstract: In a smart city, the following factors are very vital such as smart grid, e-health. Smart city is one of the burning topics of research. Although there is no particular definition of smart city, it means smart grid, e-health, e-environmental monitoring, smart home, smart water quality, smart air quality etc. integrated into a single application. Human civilisation cannot be sustained and prosper with shortage of usable water. Hence, water has a vital share in human life even living in smart cities. This paper describes about the smart water quality issues in a smart city and some of the research advances in handling those issues. Among them it investigates the rain water harvesting technologies and some of their practical applications.

           sites for aquaculture development in Purba Medinipur, West Bengal, India

      Abstract: This study focuses on two analytical frameworks (a) site suitability for fish farming (SSFF) and (b) site suitability for commercial fish farming (SSCFF) of Purba Medinipur district. Physicochemical conditions, weather, environment, establishment and profitability were selected as suitability parameters. Spatial interpolation techniques were used to generalise the distribution of water quality, soil character, precipitation and population of the fisherman family. Proximity and spatial analysis techniques were used to assign the scale for perennial River, road-rail network, market, industries, sub-division capital and density measurement respectively. The distribution of land use and land cover (LULC) and slope has been characterised as another parameter. Weightage overlay analysis has been used to evaluate the distribution of suitable sites. SSFF model shows that 19.91% area is suitable, 67.71% moderately suitable and 12.38% areas come under the unsuitable category. The SSCFF model indicated that only 12.16 % area is suitable for the economically favourable fish firming.

  • Assessment of global crop yield volatility and its association with large
           scale climate, water and temperature variability

      Abstract: In this study, anomalous spatial and temporal national-based yield values of maize, rice, sorghum and soybean from 1961 to 2013 are extracted using the multivariate statistical procedure of robust principal component analysis (RPCA). Sea surface temperature anomalies (SSTa), oceanic and atmospheric indices, air temperature anomalies (ATa) and the Palmer drought severity index (PDSI) are used to examine the association between crop yield variability in the most volatile years (MVY). Results show that warmer-than-normal winter time SSTa (El Niño) in the Pacific Ocean exerts the most dominating influence on global rice and sorghum yield volatility. In addition, extreme soybean and maize volatility are associated with mutual climatic teleconnection patterns. Since many large-scale climatic patterns are periodic and predictable seasons in advance, these findings can inform policy makers for global food security planning and management as well as global crop markets.

  • Impact of landuse change on the hydrological parameters of the watershed:

      Pages: 208 - 217
      Abstract: The present work deals with assessing the impact of landuse change on the hydrological parameter (evapotranspiration) of the watershed. To demonstrate the work, the Hathmati River that happens to be one of the most important tributaries of western India is chosen as the study area. The decadal maps of the years 1985, 1995, 2005 and 2015 have been prepared using the tools as mentioned earlier and the SWAT model is prepared to simulate the watershed. The input weather data is obtained from the state government agencies and the spatial data is extracted from CARTOSAT-1. The result shows that with the change in the green cover and agricultural land of the watershed, the hydrological parameters are affected considerably.
