Water quality assessment of the cutuchi river basin (Ecuador): A review of technical documents

2021 , Zapata D. , Oleas Gallo, Nora Helena , Páez-Vacas, Mónica , Tobes, Ibon

The Cutuchi River Basin extends over the inter-Andean valley south of the Cotopaxi Volcano, in Ecuador. It flows through two provinces, Cotopaxi and Tungurahua, and its waters are extensively used to irrigate crops that provide food to the main cities in the country. Unfortunately, the basin receives untreated domestic and industrial discharges. The need for an environmental quality assessment of the river has been acknowledged over the years. The aim of this study is to gather information about water quality of the Cutuchi River through a historical bibliographic review. A total of 57 works published between 2007 and 2018 were found, including books, articles, thesis and project reports. Only 18 documents provided biological, physical, or chemical data linked to water quality. The data obtained through the literature review were compared with maximum thresholds from national and international regulations. Unfortunately, revised studies were scattered on time and randomly along the basin and did not provide robust information to evaluate the state of the water-system. Some contamination was detected significantly exceeding safety thresholds. More exhaustive studies along the basin are needed as a baseline to help the decision makers to design management plans and mitigate human impacts. © 2020 Institute of Physics Publishing.

2021 , Cruz Cárdenas, Jorge , Guadalupe-Lanas J. , Ramos Galarza, Carlos , Oleas Gallo, Nora Helena , Salazar, Laura , Proaño-Guerrero R.

The COVID-19 crisis has generated considerable research efforts in all areas of knowledge, including the area of business and management. This article aimed to describe the body of knowledge generated on COVID-19 regarding business and management to generate the basis for future research. The present study identified 1,751 relevant articles in the Scopus database. The United States, the United Kingdom, and Australia stood out in terms scientific production, whereas the National Natural Science Foundation of China dominated in funding studies. The analysis of the co-occurrence of keywords in the articles allowed the identification of four thematic clusters that correspond to the priorities given by the research: 1) the crisis and use of technology to overcome it; 2) leadership and risk management; 3) impact on the hospitality, tourism, and air transport sectors; and 4) social impact and corporate social responsibility. This article ends by discussing these results and their implications. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
