“…There were significant relationships between CH 4 levels and DO from the generated regression model: As a step toward updating knowledge of the trophic levels of lakes Yambo, Pandin, and Calibato and examining the implications for lake CH 4 dynamics, we determined the TP concentrations in the epilimnion and hypolimnion layers of each lake (Table 3). Our TP measurements in the epilimnion layer of Yambo (0.04 ± 0.08 mg L −1 ), Pandin (0.03 ± 0.08 mg L −1 ), and Calibato (0.54 ± 0.65 mg L −1 ) were in the eutrophic (0.02-0.05 mg L −1 ) to hypereutrophic (>0.05 mg L −1 ) ranges based on Fuller and Jodoin (2016). At the same trophic levels, eutrophic to hypereutrophic conditions, based on TP concentrations, were also detected in the hypolimnion layers of lakes Yambo (0.03 ± 0.10 mg L −1 ), Pandin (0.1 ± 0.11 mg L −1 ), and Calibato (0.54 ± 0.46 mg L −1 ).…”

Controlling Factors of Methane in Tropical Lakes of Different Depths

Methane (CH 4 ) is a more potent greenhouse gas in terms of climate forcing than carbon dioxide (CO 2 ) (Forster et al., 2007;IPCC, 2018), and in the recent decades, natural sources of CH 4 have accounted for about 22%-30% of mean global CH 4 emissions (Saunois et al., 2020). Although existing estimates and models are updated periodically, our confidence in these remains low because of limited observational data. The importance of global CH 4 models that are based on well-represented estimates from different latitudinal regions has been highlighted in previous studies (Saunois et al., 2020), including studies on freshwaters (Bastviken, Tranvik, et al., 2011).While uncertainties in CH 4 estimates remain, it has been well established in landmark studies that freshwaters are the primary natural sources of atmospheric CH 4 (Bastviken, Tranvik, et al., 2011;Kirschke et al., 2013;Saunois et al., 2020). The most recent global CH 4 emission estimates (2000-2009) from freshwaters, which include lakes, ponds, reservoirs, streams, and rivers, amount to 159 Tg CH 4 yr −1 (Saunois et al., 2020). Different aquatic environments present various and unique challenges in the study of CH 4 dynamics (Hamdan & Wickland, 2016). Most of our current knowledge about CH 4 is derived from boreal and temperate aquatic ecosystems; however, it is expected that different scenarios occur in the tropics. In simulation-based bottom-up estimates by Walter et al. (2001), CH 4 emissions in aquatic ecosystems were found to be sensitive to precipitation and the water table. Nevertheless, that study emphasized that estimates should be updated with representative data from tropical regions.

The Government and Lake Governance Criteria for the Seven Crater Lakes of San Pablo City, Laguna, Philippines

The Local Government and the Government Agency shape the Seven Crater Lakes. The present study focused on understanding the predominant Governments and Lake Governance's concept vis‐a‐vis the small lakes and their basin communities. These foremost authorities are intertwined, and Lake Governance's essential criteria interplayed and continuous to the responsibility. Although the City Government of San Pablo City and the Laguna Lake Development Authority (LLDA) have improved the small lake's situations and they are satisfactorily functioning, serious issues still remain at present and into the future. Focusing on the criteria's lessons, Pandin Lake, Yambo Lake, Mohicap Lake and Sampaloc Lake have been ameliorated to varying degrees. In contrast, Bunot Lake, Palakpakin Lake and Calibato Lake continue to struggle with deficiencies. Thus, over the dual governments need to exhibit greater commitment, decisiveness and effectiveness if the Seven Crater Lakes are to flourish in development and conservation. Furthermore, while the Structuring Government and Administering Water criteria are adequate, completing the Developing Tourism, accomplishing the Regulating Fishery and substantially subsidizing the Supporting Finance in the City Government and the LLDA remain deficient. Accordingly, the main target of the paired Governments' over time is to address the remaining challenges facing the Seven Crater Lakes.

“…When considering environmental variables, it is important to assess trophic state, as it reflects anthropogenic influence on water quality and the ecological functioning of aquatic ecosystems, providing a summarised vision of organic enrichment, water transparency and phytoplankton development [22]. Several studies have indicated that the Trophic State Index is an efficient tool [23][24][25][26][27]. Riparian zone analysis is also important to evaluate water bodies.…”

Perception of the local community: What is their relationship with environmental quality indicators of reservoirs?

et al. 2022

Evaluating the conservation of aquatic ecosystems, especially those which serve to supply, has been carried out using a variety of tools. However, the perception of water quality by the local community which lives in direct contact with water resources has not been considered with enough importance. This study analysed the relationship between the conservation status of reservoirs as perceived by the local community and their conservation status according to physical, chemical, and biological indicators. To do so, we calculated the Trophic State Index (TSI) of the reservoirs, the diversity and richness of benthic macroinvertebrate and we analysed the human influence in the riparian zone. Thus, we created the Community Conservation Perception Index (CCPI) to quantitatively associate the perception of the local community with environmental quality indicators (TSI, diversity, richness and anthropogenic influences in the riparian zone). We found that interviewee perception of reservoir conservation (using the CCPI) was related to trophic state, richness and diversity of benthic macroinvertebrate, and the presence of residences and agriculture in the riparian zone. It is necessary to consider the environmental perception of the local community as a relevant factor in management programmes and the conservation of ecosystems, even if artificial, as is the case with reservoirs. These communities can significantly contribute to maintaining the environmental quality through their performance in participatory management in projects such as: participating in the investigation of pollution in reservoirs, collecting parameters related to water quality, and community action in designing conservation strategies.
