“…These approaches not only offer effective strategies for bush encroachment management but also make substantial contributions to the ecological sustainability of these semi-arid rangelands, particularly within the South African context. They present a unique viewpoint on the synergy between human activities and the natural world, a fundamental tenet of indigenous cultures in this region [54][55][56].…”

The integration of indigenous knowledge systems into the discussion of bush encroachment management is of paramount importance. Indigenous knowledge and formal monitoring may be mutually beneficial, and using both approaches can improve natural resource management. Savannah rangeland landscapes hold deep cultural and spiritual significance for indigenous communities, and their perceptions can provide valuable insights into creating more effective, community-driven conservation initiatives. This study was aimed at filling the existing knowledge and research gap on bush encroachment control by focusing on the integration of indigenous knowledge systems. To achieve this, the current research included three distinct non-probability sampling strategies: (1) Purposive, (2) Snowball, (3) Convenience sampling methods. The results showed that 90.3% of the participants indicated that the main encroaching species of concern was sickle bush (Dichrostachys cinerea) and it is therefore perceived as a problem in the rangeland. The majority of farmer respondents indicated that they cut the encroacher plant down, uproot all root systems, then burn the remaining roots. This is reported to be a more effective way of managing sickle bush as an encroacher plant. Both genders generally believe in the efficacy of these systems, with variations in levels of agreement. However, a gender disparity emerges in opinions on incorporating communal-based approaches, emphasizing the need to consider gender perspectives in environmental management initiatives. Therefore, considering this, the study concludes that a holistic approach, integrating both formal and informal knowledge systems, may be crucial for sustainable and effective management strategies. Given that, recognizing the diversity of perspectives within the community, particularly regarding gender differences, is essential for developing inclusive and community-driven environmental management initiatives.

“…Although water resources are essential for life on Earth, the growing human population, combined with global environmental change, particularly climate change and variability, has put a strain on this finite resource and the environment [1]. Water scarcity caused by rapid population growth, droughts [2][3][4], erratic rainfall [5], overexploitation, and increased water pollution [6] from anthropogenic activities, such as mining and urbanization, pose a threat to the supply of usable quality and quantity of water to meet the demand [7]. This is especially concerning, given that approximately one-fifth of the world's population lives in water-stressed areas, and this trend is likely to worsen in the near future if the current trends, threats, and pressures are not fully understood and managed appropriately [2].…”

In line with the United Nations Sustainable Development Goal (SDG) 6, the main goal of the Special Issue on “Remote sensing for water resources and environmental management” was to solicit papers from a diverse range of scientists around the world on the use of cutting-edge remote sensing technologies to assess and monitor freshwater quality, quantity, availability, and management to ensure water security. Special consideration was given to scientific manuscripts that covered, but were not limited to, the development of geospatial techniques and remote sensing applications for detecting, quantifying, and monitoring freshwater water resources, identifying potential threats to water resources and agriculture, as well as other themes related to water resources and environmental management at various spatial scales. The Special Issue attracted over thirteen peer-reviewed scientific articles, with the majority of manuscripts originating from China. Most of the studies made use of satellite datasets, ranging from coarse spatial resolution data, such as the Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow-On (GRACE-FO), to medium spatial resolution data, such as the Landsat series, ERA5, Modern-Era Retrospective Analysis for Research and Application Land version 2 reanalysis product (MERRA2), CLSM and NOAH ET, and MODIS (Moderate Resolution Imaging Spectroradiometer). Google Earth Engine (GEE) data, together with big data processing techniques, such as the remote sensing-based energy balance model (ALEXI/DisALEXI approach) and the STARFM data fusion technique, were used for analyzing geospatial datasets. Overall, this Special Issue demonstrated significant knowledge gaps in various big data image processing techniques and improved computing processes in assessing and monitoring water resources and the environment at various spatial and temporal scales.
