“…Fish farming activities around the lake cause nutrient pollution due to excessive nitrogen and phosphorus concentration (Henny et al, 2016). Excessive nitrogen and phosphorus can cause eutrophication and a lack of dissolved oxygen, leading to massive fish kill (De Maisonneuve et al, 2019).…”

Maninjau Lake is one of Indonesia's lakes for hydroelectric power plants, tourism, and fish farming activities. Some activities around the lake cause pollution, leading to massive fish kill. Therefore, it is necessary to monitor water quality regularly. One of the critical water quality parameters is biochemical oxygen demand (BOD). This study aimed to analyze BOD changes using a remote sensing approach during massive fish kills in Maninjau Lake, Indonesia. Multi-temporal Landsat-8 satellite images are processed to estimate the BOD level based on Wang Algorithm. After that, the estimated BOD value is validated using in situ data measurement. The results of the average BOD concentration that occurred in Lake Maninjau was 1.85 mg/L and showed that R2 was 0.8334, and the standard error was 0.076 between the estimated BOD and in situ data. Furthermore, the average concentration of BOD obtained on 23rd August 2017, 13th December 2017, 30th January 2018, 19th March 2018, and 7th July 2018 are 4.96 mg/L, 4.82 mg/L, 5.31 mg/L, 6.94 mg/L, and 6.60 mg/L, respectively. Increased BOD concentration in January 2018 indicates moderate pollution in the waters. BOD concentration increases after the massive fish kill due to the decaying fish across the lake.

Persistent natural disasters in Maninjau, mainly landslide, and fish death, have affected the local society income in the tourism destination of Maninjau, Agam Regency West Sumatra, Indonesia. This research aims to identify the effect of natural disasters on local society's income. The research was conducted using the survey method. Samples were collected (300 respondents) from 3 Nagari in Maninjau Resort, especially Nagari Sungai Batang (location of the Buya Hamka Museum), Maninjau, dan Bayua. The parameters identified were the income of local society and the type of economic activity they want to develop. The collected data was classified into categories, then the percentage was calculated, and finally presented in a pie chart. Based on data, it was found that natural disasters, especially landslides and fish deaths in the lake, significantly decreased the local society income. Most (81.7%) of society decreased their income by 40%. The income reduction was not only due to the property loss but also associated with the decrease in tourist visits. To recover the economic growth in Maninjau, most of the community (87.7%) wanted tourist visits increased. Then, they also wanted to develop culinary business (41.5%), agroforestry (29.9%), and religious tourism (26%), especially Hamka Tourism in Sungai Batang. An alternative way to recover quickly and to increase local society's income can be done through online promotion. Website development of each industry in Maninjau is really suggested.

“…It should also be emphasised that the availability of bathymetric maps permits the determination of the primary morphometric properties of lakes, and is important for the calculation of the water, thermal, and chemical balances of these elements of the hydrosphere [13]. Therefore, knowledge concerning lake bottom relief is a frequently discussed issue in hydrological research [14][15][16][17][18]. In this context, studies concerning changes in isobaths reflecting the transformations of bottom topography should be considered scarce [19][20][21].…”

Changes in the Water Resources of Selected Lakes in Poland in the Period 1916–2020 as Information to Increase Their Availability

et al. 2021

The historical effects of land development on water management currently require a new approach, in many cases involving attempts at the restoration of the quasi-natural state. This is evident in reference to many regions in Poland, where the hydrographic network has been diminishing over the centuries, among others in favour of obtaining new agricultural land. Such activities overlap with natural processes causing transformations of the hydrosphere. The most serious problems currently include water deficits resulting from climate change and human activity. This paper employed archival bathymetric maps from the beginning of the 20th century for the determination of the scale of changes in the morphometric parameters of six lakes in western Poland. It was determined that over a period of more than a hundred years, the surface area (12.2%) and original volume of water bodies (13.9%) were largely reduced. This situation was caused by both natural (overgrowing and shallowing) and anthropogenic (change in water level) factors. The obtained information points to the need of an inventory of historical bathymetric maps of lakes. In combination with modern research, this will allow for the determination of changes in the water resources of lakes and, in a longer-term perspective, potential possibilities of their renaturisation. This knowledge is important in the context of the reconstruction of water resources in the territory of Poland, where their deficits are recorded increasingly frequently. It should also be emphasised that the restoration of the natural capacity of water retention in lakes is a more economical solution and, most importantly, it is not invasive for the environment.
