Abstract. The Lake Athabasca drainage area in northern Canada encompasses ecologically rich and sensitive ecosystems, vast forests, glacier-clad mountains, and abundant oil reserves in the form of oil sands. The basin includes the Peace–Athabasca Delta, recognized internationally by UNESCO and the Ramsar Convention as a biologically rich inland delta and wetland that are now under increasing pressure from multiple stressors. In this study, streamflow variability and trends for rivers feeding Lake Athabasca are investigated over the last half century. Hydrological regimes and trends are established using a robust regime shift detection method and the Mann–Kendall (MK) test, respectively. Results show that the Athabasca River, which is the main contributor to the total lake inflow, experienced marked declines in recent decades impacting lake levels and its ecosystem. From 1960 to 2010 there was a significant reduction in lake inflow and a significant recession in the Lake Athabasca level. Our trend analysis corroborates a previous study using proxy data obtained from nearby sediment cores suggesting that the lake level may drop 2 to 3 m by 2100. The lake recession may threaten the flora and fauna of the Athabasca Lake basin and negatively impact the ecological cycle of an inland freshwater delta and wetland of global importance.

This study presents the first bathymetric surveys and descriptions of the morphometric parameters of the major lakes of the national park and Ramsar Convention site <em>Lagunas de Montebello</em>, Chiapas, Mexico and represents the first contribution on these limnologically unknown lakes. The morphology of lacustrine basins has an important influence on the physical, chemical and biological dynamics, and limnological research must consider the bathymetry and the related morphometric parameters of the lakes. Of the more than 50 lakes that make up this karst lake system (including dolines, uvalas and poljes), 18 representative lakes were selected along a NW-SE transect. The lakes have widely varying dimensions and include small and deep, small and shallow, large and deep, and large and shallow lakes. The shapes of the lakes vary from circular to elliptical, and the basin resembles an inverted truncated cone. The orientation of the main axis follows the structural orientations of the karst landscape (i.e., faults, fractures and folds). The maximum lengths range from 0.14 to 3.2 km, the surface areas range from 1.1 ha to 306.6 ha, and the lake volumes range from 0.00004 to 0.08852 km<sup>3</sup>. Six lakes are among the deepest lakes in Mexico and have an average maximum depth of more than 50 m; the deepest lake has a maximum depth of 198 m. These depths favor prolonged stratification, which increases the probability of accumulating pollutants.

Wetland ecosystems are one of the highly productive ecosystems in the world. These ecosystems have been deteriorating at a faster rate. Ramsar Convention is putting enormous effort to protect, maintain, and restore these ecosystems. Currently, the fourth phase of Strategic Plans of Ramsar Convention is going on, in which saline wetlandscapes can play vital role to attain 19 targets of this plan. In India there are 27 Ramsar sites in all the biogeographic zones; however, research work has been carried out in the past five years in only eight Ramsar sites. Currently, four years are available for the strategic plans to encourage more wetland researches. The chapter presents a case study of Sambhar Salt Lake, a Ramsar site of India that is on the verge of extinction. Normalized Difference Water Index has been calculated for three decades in 1992, 2009, and 2019, revealing the declining phases of the lake.
