They generate a large amount of wastewater through various sources which are very complex and hazardous. Furthermore, the emission of healthcare wastewater into the cities sewerage, rivers and groundwater pollute the entire system. Therefore, disposal of\u0000healthcare wastewater without adequate treatment can cause short and long-term ill-effects to the public's health. An onsite wastewater treatment would give a dual benefit of preventing the release of hazardous materials into other sources and bring the wastewater into the consumption cycle. At present, most countries utilize the treated\u0000wastewater to reduce the consumption of potable water. However, the literature review and preliminary studies revealed that wastewater management is poorly practised in the Sri Lankan healthcare sector. Therefore, this paper aimed to identify the extent of wastewater treatment, utilization and management in Sri Lankan state sector\u0000hospitals. The aim of the paper was achieved through a literature review and questionnaire survey. The required data were collected from nine state hospitals in Colombo. Findings of the study revealed that a high quality of wastewater treatment and efficient reuse of reclaimed water is a big challenge for the healthcare sector due to the\u0000complex nature of the wastewater process, higher cost of treatment and poor management. Moreover, it was found that currently wastewater generated from the state hospitals are discharged directly into the city's sewerage without any treatment. Finally, this paper discusses the current level of wastewater treatment, utilization and management in the state hospitals and identifies the critical barriers for the lack of poor practice of wastewater\u0000handling.","PeriodicalId":443502,"journal":{"name":"Journal of Water Engineering and Management","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123750500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Land-use and climatic change in this region has negative impacts on agriculture and human health. Increasing temperature, erratic precipitation, and rising CO2 concentrations are the main drivers which show adverse effects on agriculture and human health. The impacts trends in this region can be categorised into exacerbated pathogenicity are pathogens, and hence disease outbreaks, changes in the traditional agriculture techniques, and people’s migration that directly changes in ecological and leading to social inequalities. In the last few decades, there have been changes in vector species distribution in agriculture and increases of forest pest species attacks by climate change in agriculture and forest pest increases, and parasites are emerging during periods of these last few decades. Enhancement of seasonal transmission and distribution of pests pushes food insecurity and vector-borne infections deteriorate human health. This review article tries to analyse different literature on the effects of climate change on agriculture and human health in the Western Himalayas and suggest agroforestry and agroecology is some of the strategies to overcome climate change impact.","PeriodicalId":443502,"journal":{"name":"Journal of Water Engineering and Management","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115115774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work, therefore, examined the changes of precipitation and temperature under all Representative Concentration Pathway (RCP2.6, 4.5, 6.0, and 8.5) scenarios of climate change in the Sikkim Himalayan region of India. The datasets from two different global circulation models (GCMs) have been used to analyseSikkim’s;s daily precipitation and temperature for the near, mid, and far future. The linear scaling bias correction method (LCBCM) was employed to remove the bias because of a significant difference between the raw and observed monthly climate data for both GCMs.The predictions based on bias-corrected GCMs data under all RCP scenarios indicated that Tmax and Tmin are projected to increase in the near, mid and far futures. The projection of CSIRO_MK 3.6 model indicated that the increase in Tmax from near to far ranges from 1.0 to 1.5°C, 0.8 to 2.8°C, 0.4 to 2.3°C and 0.5 to 4.2°C under the four scenarios, respectively. Similarly, the projected to increase in Tmin from near to far ranges from 1.5 to 2.0°C, 1.1 to 3.5°C, 0.5 to 3.0°C and 0.8 to 4.5°C in RCP 2.6, 4.5, 6.0 and 8.5 scenarios, correspondingly. The results also showed that in climate change scenarios, the rate of precipitation is expected to increase, which could lead to the rise of snowmelt and flooding in the near future. This study is recommended to increase the number GCMs in future studies to reduce the uncertainty in future prediction and utilize the LCBC method for bias correction.","PeriodicalId":443502,"journal":{"name":"Journal of Water Engineering and Management","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126019189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The drop of soil moisture and temperature has an impact involving climate, vegetation and drought. The presence of soil moisture does not ensure its availability to a crop but the force by which water is held by soil particle is important. The amount of work done to extract soil moisture is generally expressed as stress. It is necessary to understand the extent of stress for proper water resources management. The soil moisture index (SMI) is a criterion that denotes the extent of stress experienced by a crop. The temperature also has an impact on germination and production. In the present study, we developed a SMI for different locations in Sikkim. The index ranges from +5 to -5. The negative index indicates extreme stress. The study indicated during winter the index goes beyond-3. Considering wilting point stress as 500 and 700 kPa. The soil temperature was also observed to fall below 15 C. Further, it was observed that soil temperature and moisture are strongly correlated to each other. The SMI can play an important role in adopting suitable water management practices for improved crop production.","PeriodicalId":443502,"journal":{"name":"Journal of Water Engineering and Management","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131973200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
