Estimating thresholds of natural vegetation for the protection of water quality in South African catchments

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 945, P. 173924 - 173924

Published: June 15, 2024

Many of South Africa's current water quality problems have been attributed to diffuse pollution derived from poorly regulated land use/land cover (LULC) transformations. To mitigate these impacts, the preservation an adequate amount natural vegetation within catchment areas is important management strategy. However, it not clear how much required provide levels protection, nor at which scale(s) this strategy would be most effective. investigate possibility estimating minimum thresholds protect resources, regression analysis was used model relationships between (measured using Nemerow's Pollution Index) and metrics multiple scales across a sample sub-catchments located along western, southern, south-eastern coast Africa. With conspicuous outliers removed, models were able explain up 82 % variability in relationship use quality. Moreover, statistically significant, nonlinear, inverse found proportions levels. This strongest when measured (1) whole (2) 200 m riparian buffer zone. The further indicated that approximately 80 90 necessary maintain ecologically acceptable Additional nonlinear estimated breakpoint suggested if fall below 45 (across catchment) 60 (within zone) dramatic increase can expected. are recommended as guidelines inform integrated resources strategies aimed protecting study area. Likewise, methods described for estimation similar other regions.

Riparian Landscape Change: A Spatial Approach for Quantifying Change and Development of a River Network Restoration Model

Environmental Management, Journal Year: 2024, Volume and Issue: 74(5), P. 853 - 869

Published: Aug. 20, 2024

Natural river landscapes can be biodiversity hotspots but are one of the most human altered ecosystems with habitats significantly damaged around world, and a third fish populations threatened extinction. While riparian have been negatively by anthropogenic activities, effective planning restoration strategies reverse negative impacts improving habitat quality. However, restoring rivers requires appropriate data on current health while also considering priorities for different stakeholders. To address this, Geographic Information System (GIS) was used to create new transferable priority model based section Linth in Switzerland as case study. The is founded connectivity, condition, national species hotspots. Landscape change zone analyzed using aerial imagery landscape metrics. Almost quarter within study area were considered high or very priority, many aquatic set benefit from restoration. From 1946 2019, became highly fragmented due significant growth impervious surfaces concomitant loss agricultural land. GIS provides tool which environmental agencies manage natural features over large scales, targeting conservation areas greatest need.
