“…Native weed communities may have genetic characteristics that make them less prone to invasion (Weidenhamer et al, 2023). They may exhibit genetic changes that enable improved stress tolerance or efficient nutrient use, strengthening their resistance to disturbance (Bailey-Serres et al, 2019;Voolstra et al, 2021). Whole-genome analysis can be used to pinpoint these characteristics, for example genome editing using clustered regularly interspaced palindromic repeats-associated protein 9 (CRISPR/Cas9) has used to increase temperature tolerance in several plant species (Blomme et al, 2022;Cardi et al, 2023).…”

“…Controlling invasive species in polluted environments requires a multifaceted approach that addresses both the invasive species and pollutants (Khan et al ., 2023 a ). The presence of pollutants can alter the control methods and complicate the overall management process (Badrzadeh et al ., 2022). A comprehensive assessment of the pollution sources and their impact on the ecosystem is necessary, followed by implementation of appropriate pollution‐control measures such as sediment dredging, phytoremediation, or the introduction of pollutant‐degrading microorganisms (Haller et al ., 2021).…”

Weed communities influence the dynamics of ecosystems, particularly in disturbed environments where anthropogenic activities often result in higher pollution. Understanding the dynamics existing between native weed communities and invasive species in disturbed environments is crucial for effective management and normal ecosystem functioning. Recognising the potential resistance of native weed communities to invasion in disturbed environments can help identify suitable native plants for restoration operations. This review aims to investigate the adaptations exhibited by native and non‐native weeds that may affect invasions within disturbed environments. Factors such as ecological characteristics, altered soil conditions, and adaptations of native weed communities that potentially confer a competitive advantage relative to non‐native or invasive weeds in disturbed environments are analysed. Moreover, the roles of biotic interactions such as competition, mutualistic relationships, and allelopathy in shaping the invasion resistance of native weed communities are described. Emphasis is given to the consideration of the resistance of native weeds as a key factor in invasion dynamics that provides insights for conservation and restoration efforts in disturbed environments. Additionally, this review underscores the need for further research to unravel the underlying mechanisms and to devise targeted management strategies. These strategies aim to promote the resistance of native weed communities and mitigate the negative effects of invasive weed species in disturbed environments. By delving deeper into these insights, we can gain an understanding of the ecological dynamics within disturbed ecosystems and develop valuable insights for the management of invasive species, and to restore long‐term ecosystem sustainability.

“…Priority planting area for L. chuanxiong under RCP 6.0 and RCP 8.5 in 2070. Hence, it is necessary to plan and manage planting areas based on a diversified approach under soil pollution by heavy metals and climate change (Bytnerowicz et al, 2007;Sverdrup et al, 2007;Badrzadeh et al, 2022). The sources of soil pollution by heavy metals are diverse, and the soil remediation process is long; this affects the distribution of cash crops and further affect agricultural income and the planting of crops (Dong et al, 2001;Dach and Starmans, 2005;Nabulo et al, 2010;Lu, 2019).…”

IntroductionSoil pollution by heavy metals and climate change pose substantial threats to the habitat suitability of cash crops. Discussing the suitability of cash crops in this context is necessary for the conservation and management of species. We developed a comprehensive evaluation system that is universally applicable to all plants stressed by heavy metal pollution.MethodsThe MaxEnt model was used to simulate the spatial distribution of Ligusticum chuanxiong Hort within the study area (Sichuan, Shaanxi, and Chongqing) based on current and future climate conditions (RCP2.6, RCP4.5, RCP6.0, and RCP8.5 scenarios). We established the current Cd pollution status in the study area using kriging interpolation and kernel density. Additionally, the three scenarios were used in prediction models to simulate future Cd pollution conditions based on current Cd pollution data. The current and future priority planting areas for L. chuanxiong were determined by overlay analysis, and two levels of results were obtained.ResultsThe results revealed that the current first- and secondary-priority planting areas for L. chuanxiong were 2.06 ×103 km2 and 1.64 ×104 km2, respectively. Of these areas, the seven primary and twelve secondary counties for current L. chuanxiong cultivation should be given higher priority; these areas include Meishan, Qionglai, Pujiang, and other regions. Furthermore, all the priority zones based on the current and future scenarios were mainly concentrated on the Chengdu Plain, southeastern Sichuan and northern Chongqing. Future planning results indicated that Renshou, Pingwu, Meishan, Qionglai, Pengshan, and other regions are very important for L. chuanxiong planting, and a pessimistic scenario will negatively impact this potential planting. The spatial dynamics of priority areas in 2050 and 2070 clearly fluctuated under different prediction scenarios and were mainly distributed in northern Sichuan and western Chongqing.DiscussionGiven these results, taking reasonable measures to replan and manage these areas is necessary. This study provides. not only a useful reference for the protection and cultivation of L. chuanxiong, but also a framework for analyzing other cash crops.

“…While this adjustment defines progress in the bottom-up dialogue process, the process can facilitate the identification of risk sources at locations of potential economic deposits within the Watersheds (River Basins); especially by means of effective cross-sectoral co-ordination between policies for water and various land uses [Principle 3]. Identifying highly polluting areas can provide a valuable system for more cost-effective watershed management (Badrzadeh et al, 2022). Thus, the water governance system in Nigeria must be fortified with adherence to the OECD Principles on Water Governance to provide novel input indicators that monitor actions that contribute to good outcomes, including budgeting/planning for risk assessment, regulatory, and preventive predictive measures.…”

Conflicts of interest due to cultural, political, and social oversights have threatened effective and efficient corporate water governance in Nigeria. This has affected the inclusive participation of stakeholders, policy makers and the relevant agencies of the water resources management, thus hampering good water governance. Assessing the water governance impacts based on frameworks proposed for effective, efficient and inclusive governance was aimed. Information contributing to the governance input was highlighted by analyzing hydrological units that characterized Nigerian watersheds. Toxicological index (Ti) values were presented as a practical guideline to assessing water policy outcomes. The (Ti) ≥ 1.0 dominated; signifying the water resources exposed to toxic environments. High pollutant loads associated with public health deterioration across Nigeria are considered as impacts indicating lagged water governance. While the lagged governance output manifested in some diseases relating to deficient access to potable water supply/poor sanitation services like Blue baby syndrome, Renal/liver/lung diseases and blood cancer, the outcome showed an absence of health and social wellbeing. These indicators demonstrate the need for incorporating Organization for Economic Co-operation and Development (OECD) Principles on Water Governance in the Nigerian water governance system. Notably, flexibility across all governance levels can enable shared responsibility to balance economic activities with the ecological wellbeing.
