“…Maintaining the water quality of water resources requires continuous monitoring of the physicochemical and bacteriological characteristics of the water [ 20 , 21 , 22 ]. By monitoring the water quality, it is possible to detect any variation that occurred, determining the reasons for such variations, and finding some possible solutions [ 23 , 24 , 25 ]. There could be many reasons why the water quality in a lake or reservoir is altered.…”

“…Lopes et al [ 28 ] mention that other factors can influence water quality, such as thermal stratification, erosive rain events, the presence of natural biofilters, and landscape patterns in the surrounding areas. These water quality studies have identified key water quality variables that influence physical, chemical, and biological processes in water bodies [ 24 , 25 , 26 , 27 , 28 ].…”

Agricultural activities are highly related to the reduction of the availability of water resources due to the consumption of freshwater for crop irrigation, the use of fertilizers and pesticides. In this study, the water quality of the Adolfo López Mateos (ALM) reservoir was evaluated. This is one of the most important reservoirs in Mexico since the water stored is used mainly for crop irrigation in the most productive agricultural region. A comprehensive evaluation of water quality was carried out by analyzing the behavior of 23 parameters at four sampling points in the period of 2012-2019. The analysis of the spatial behavior of the water quality parameters was studied by spatial distribution graphs using the Inverse Distance Weighting interpolation. Pearson correlation was performed to better describe the behavior of all water quality parameters. This analysis revealed that many of these parameters were significantly correlated. The Principal Components Analysis (PCA) was carried out and showed the importance of water quality parameters. Ten principal components were obtained, which explained almost 90% of the total variation of the data. Additionally, the comprehensive pollution index showed a slight water quality variation in the ALM reservoir. This study also demonstrated that the main source of contamination in this reservoir occurs near sampling point one. Finally, the results obtained indicated that a contamination risk in the waterbody and further severe ecosystem degradations may occur if appropriate management is not taken.

“…Reservatórios são ecossitemas artificiais formados pelo barramento de rios, desse modo, seu próprio estabelecimento altera as caracterísiticas ambietais naturais, fazendo que muitas espécies não consigam se estabelecer. No referido estudo, a maior riqueza que espécies foi representada por moluscos gastrópodes, os quais conseguem respirar utilizando o oxigênio atmosférico, assim o oxigênio da água não é um fator limitante para esses organismos, sendo classificados como bioindicadores tolerantes à degradação ambiental (Goulart;Callisto, 2003;Azevêdo et al, 2018). Mesmo assim, apenas um reservatório (Jatobá II) apresentou maior riqueza de moluscos, o que evidencia que as condições ambientais nos demais reservatórios (Macapá e Cruzeiro) podem ser ainda mais degradantes, não permitindo o estabelecimendo, até mesmo, de organismos tolerantes.…”

“…For instance, where river water serves as a source of tourism and recreation, stakeholders are likely to be concerned about the aesthetic value of the river (Barnett, Jackson‐Smith, & Haeffner, ) and are more likely to be motivated to protect its quality (Bouwer, ; Kohlmann et al, ; Buijs, ). Where the river is a major source of water for drinking and cooking, stakeholders may be concerned about the health risks associated with consuming polluted water (de Lira Azevêdo et al, ). These concerns may trigger positive attitudes and willingness to protect rivers.…”

There is evidence that stakeholders' willingness and motivations to support sustainable river management strategies plays a crucial role in the success of water management policies. Earlier works have highlighted some of the drivers of stakeholders' willingness, however, the generalizability of much published research on this issue is problematic given that much of the research focuses on the Global North. By conducting in‐depth interviews and applying content analysis, this paper aimed at exploring stakeholders' willingness and motivations to support sustainable water resource management as well as what stakeholders would do to support sustainable management of water resources. Results show that stakeholders appear to be willing to support water protection measures due to a wide range of motivations. Therefore, policymakers may need to emphasize those motivations when encouraging the public and/or segments of the society to engage in sustainable water resource management practices.
