“…303 reaching this target, achieving 100 percent for all targets of SDG 6 is dubious, as political involvement hinders the decision-making process. 129 The country faces serious issues related to corruption, which makes the enforceability of laws and regulations a real problem, and the consequence is the existence of good legislation that is not being complied with and the environmental results are not being achieved. 130 In terms of SDG 14, life below water, the analysis is more complex than the previously analyzed SDG 6.…”

“…Naturally, fragile environments are pressured by this expansion, since agriculture activity releases chemicals considered toxic to flora, fauna, and human health 9 , 10 . In this regard, HS stand out as a fragile ecosystem responsible for hydrological and biogeochemical cycles with fauna and flora 11 , 12 . These soils are connected with the water table and represent a supplier for water recharge nutrients and sediments for riverine ecosystems 13 .…”

The pressure for food production has expanded agriculture frontiers worldwide, posing a threat to water resources. For instance, placing crop systems over hydromorphic soils (HS), have a direct impact on groundwater and influence the recharge of riverine ecosystems. Environmental regulations improved over the past decades, but it is difficult to detect and protect these soils. To overcome this issue, we applied a temporal remote sensing strategy to generate a synthetic soil image (SYSI) associated with random forest (RF) to map HS in an 735,953.8 km2 area in Brazil. HS presented different spectral patterns from other soils, allowing the detection by satellite sensors. Slope and SYSI contributed the most for the prediction model using RF with cross validation (accuracy of 0.92). The assessments showed that 14.5% of the study area represented HS, mostly located inside agricultural areas. Soybean and pasture areas had up to 14.9% while sugar cane had just 3%. Here we present an advanced remote sensing technique that may improve the identification of HS under agriculture and assist public policies for their conservation.

“…Sreeja et al [21] noted that incorporating coastal stretches as an integral part of the watershed becomes necessary due to the reciprocal relationships that exist between coastal 'tail-end' ecosystems and upstream stretches. Santana et al [22] proposed that international society has begun to consider river watersheds and the coastal zone as one management unit that requires an ecosystem approach.…”

Integrated Zoning and Spatial Heterogeneity of Coastal Watershed-Nearshore Waters

Integrated land-sea development and protection are important for the sustainable development of coastal areas. To promote the transition from separate land-sea management to integrated land-sea governance, the scientific delineation of the integrated spatial zoning units of coastal watershed-nearshore waters is an important tool for integrated land-sea management. From the perspective of physical geography, this study uses digital hydrological analysis based on DEM data to determine the coastal basin range and generate multilevel watersheds and river networks using different thresholds, and establishes spatial correspondence among physical geospatial spaces, such as watershed zones, coastlines, and nearshore waters, after considering the boundaries of major estuaries and bays. On this basis, the coastal zone is divided into several integrated spatial zoning units of coastal watershed-nearshore waters, and a physical geography-based integrated spatial zoning method is developed to form a physical geography-based land-sea integrated spatial zoning scheme. This study conducted spatial heterogeneity research of the integrated spatial zoning units, from the perspectives of topography analysis, land use analysis, socioeconomic analysis of the watershed, sea use analysis, seawater quality analysis of the nearshore waters, and load pressure analysis of the watershed-nearshore waters. The elemental differences of zoning units are studied in detail, which can provide a data reference for establishing the relationship between watersheds and nearshore waters. Applying this research method to the Guangxi Zhuang Autonomous Region in China, where the land-sea linkage pattern is forming, can provide a spatial reference and scientific basis for land-sea integrated management for ecological protection and sustainable resource utilization in the coastal zone.
