“…The Cubatão River Watershed (BHRC) (Figure 1), 26 • 16 51.09" S 48 • 45 54.80" W, in Southern Brazil, covers an area of 492 km 2 [34], the altitude varies from 0 to 1500 m above the mean sea level. Regarding the climate, based on the Köppen classification, its climate is Cfa (mesothermic, humid, and no dry season) in the plainand Cfb (mesothermic, humid, and a mild summer) in the upland regions [35][36][37], and the average annual precipitation is 2182.6 mm.…”

“…It is responsible for the public water supply of 75% of the population of the Joinville municipality, or approximately 450,000 inhabitants [38,39]. The watershed is in the Atlantic Rainforest domain; vegetation is present in the medium/advanced phase in most of the area (around 76% of the region is composed of a forest formation) [34,40]. Economically, the service-providing and industrial sectors are the most important to the region [41].…”

Water–Energy–Food Security Nexus—Estimating Future Water Demand Scenarios Based on Nexus Thinking: The Watershed as a Territory

Water, energy, and food security are essential for maintenance and human survival. This research applied an approach for the water–energy–food system to a watershed in the Atlantic Rainforest in Southern Brazil. It is based on a WEAP system that was developed and evaluated future water demand scenarios for the 2020–2050 timespan. The Sustainability Index (SI) was used to assess the scenarios to propose an alternative to compare the current development trend. The results indicated that by 2050, the necessary flow for different water uses would be 78.75% greater than in 2020 while maintaining the present scenario (C_REF). Substituting part of the hydroelectric energy by photovoltaic solar energy (C_EAL), implementing watershed action masterplans as a water resource instrument (C_GES), and integrating these scenarios (C_INT) will reduce the current demand ranging from 8.96% to 24.59%. The average flow would decrease by 28.44% and 29.07%, respectively, by evaluating water availability in climatic change scenarios (C_MCL) for the RCP 4.5 and 8.5 scenarios. Compared with the reference scenario C_REF, C_INT presented an improved SI (0.1231), while C_MCL 8.5 presented the worse (−0.0047). Therefore, resources must be generated holistically so that one segment does not negatively impact the others. The findings highlight the pressing need for Santa Catarina State to implement effective management strategies targeting specific sectors, particularly the industrial and human consumption supply sectors. It is imperative to propose adaptation plans and implement actions that foster the reduction in water demands while also providing subsidies and guidance to the industrial sector on responsible water usage to prevent any negative impact on their productivity in the future. Comprehensive plans and policies should be formulated to ensure integration and coherence among various sectors involved in water resource management.

“…Only Cambeva cubataonis (Bizerril, 1994) was formally described for GBIA [23], which is part of the Atlantic Forest, one of the most threatened and richest biomes on earth [24][25][26][27]. In GBIA, most original forests located on the coastal plain were extirpated to make way for plantations, industries and urban centres [28]. Consequently, some rivers located in the GBIA have high levels of physical degradation and pollution, making fish species vulnerable or even highly endangered [29].…”

A recent field inventory focusing on catfishes of the trichomycterine genus Cambeva detected the occurrence of two morphotypes, C. barbosae and C. cubataonis, in the Guaratuba-Babitonga-Itapocu area (GBIA) of southern Brazil, reporting some discordance with results of coalescent-based approaches for species delimitation that indicated different estimates of species number. Contrastingly, based on examination of characters taken from the external morphology and osteology, we here recognised six species of Cambeva in GBIA: C. cf. botuvera, a polymorphic and geographically widespread species; C. cubataonis, endemic to the Rio Cubatão do Norte; and four new species, two endemic to the Rio Itapocu basin, one endemic to the Baía de Babitonga system and one endemic to the Baía de Guaratuba system. We performed a molecular phylogenetic analysis indicating that Cambeva comprises three major clades, the alpha-, beta- and gama-clades, with C. cf. botuvera and a clade comprising C. cubataonis and three new species belonging to the beta-clade and another new species belonging to the gama-clade. We concluded that species here recognised are not in fact incongruent with results of that recent study when taxa are correctly identified by a representative sample of morphological characters, highlighting the importance of osteological characters for delimiting trichomycterine species.
