“…Given the uneven distribution of global groundwater (Kretschmer et al., 2023), inequitable access and the limited replenishment of ancient global groundwater reserves, shifts in the dependence of ecosystems from surface to groundwater will be spatially variable (Link et al., 2023; López‐Corona et al., 2013). Therefore, effective groundwater governance will be a crucial aspect to mitigate the impact of droughts on economies, societies and diverse environments (Petersen‐Perlman et al., 2022).…”

Groundwater is a vital ecosystem of the global water cycle, hosting unique biodiversity and providing essential services to societies. Despite being the largest unfrozen freshwater resource, in a period of depletion by extraction and pollution, groundwater environments have been repeatedly overlooked in global biodiversity conservation agendas. Disregarding the importance of groundwater as an ecosystem ignores its critical role in preserving surface biomes. To foster timely global conservation of groundwater, we propose elevating the concept of keystone species into the realm of ecosystems, claiming groundwater as a keystone ecosystem that influences the integrity of many dependent ecosystems. Our global analysis shows that over half of land surface areas (52.6%) has a medium‐to‐high interaction with groundwater, reaching up to 74.9% when deserts and high mountains are excluded. We postulate that the intrinsic transboundary features of groundwater are critical for shifting perspectives towards more holistic approaches in aquatic ecology and beyond. Furthermore, we propose eight key themes to develop a science‐policy integrated groundwater conservation agenda. Given ecosystems above and below the ground intersect at many levels, considering groundwater as an essential component of planetary health is pivotal to reduce biodiversity loss and buffer against climate change.

“…https://doi.org/10.1017/cft.2022.11 Published online by Cambridge University Press Some problems related to drought and groundwater management are caused by governance misalignments (Petersen-Perlman et al, 2022). For example, the Salento aquifer in Italy is experiencing groundwater salinisation and despite droughts in the area, salinity effects are not considered in groundwater management practices and no systematic monitoring takes place (Parisi et al, 2018).…”

“…In addition, advances have been made in the understanding of aquifer vulnerability in terms of both volume and quality during droughts related to pumping and pollution. However, the effects of augmentation strategies such as MAR need to be incorporated more sufficiently (Petersen-Perlman et al, 2022). Finally, it is essential that issues related to groundwater use during https://doi.org/10.1017/cft.2022.11 Published online by Cambridge University Press droughts are effectively communicated and that local stakeholders participate in managing groundwater resources (Petersen-Perlman et al, 2022).…”

Urbanisation and population growth are concentrated at the coast with approximately 40% of the human population living within 100 km of the ocean.The freshwater systems on which coastal urban areas rely are vulnerable to bidirectional pressures including coastal processes such as sea-level rise and coastal erosion and land use changes and pollution occurring in inland catchment areas. These threats are likely to be amplified in the future under climate change conditions and more frequent and severe drought periods are expected to jeopardise already constrained water supply systems. Groundwater is used as a freshwater resource globally and is especially important as conjunctive supply during drought periods due to perceived buffer capabilities.However, several threats impact coastal aquifers due to over-abstraction, such as salinisation, land subsidence and groundwater flooding and often these

“…These temperature increases lead to drought event over time (Ault 2020). Drought event has a very complex structure and can be defined as a natural disaster with unpredictable social, economic, political and environmental effects (Petersen-Perlman et al 2022;Aydin and Oz 2021).…”

This study aims to examine the effects of economic growth, energy usage, trade openness and foreign direct investment on carbon dioxide (CO2) emissions for G8 countries using annual data for the period 1990–2018. For this purpose, this study primarily follows the cross-section dependence and heterogeneity tests. Then, unit root and cointegration tests, cointegration analyzes and causality analyzes are performed in the study. Finally, the article estimates short-term parameters and long-term parameters to capture possible dynamic relationships between variables. The Westerlund Error Correction Model (ECM) panel test for cointegration shows that there is a cointegration relationship between these variables for both the entire panel and the cross-section units. Augmented Mean Group (AMG) estimator method shows that economic growth has no effect on CO2 emissions in the majority of the countries studied, energy usage increases CO2 emissions, while foreign direct investments and trade openness do not affect CO2 emissions in some countries, but positively effects in some countries and negatively in others. According to the results obtained from the Pooled Mean Group (PMG) analysis, it has been determined that economic growth, energy usage and trade openness are important to explain the change in CO2 emissions in the long run, while energy usage and trade openness are important to explain the change in CO2 emissions in the short run too, but economic growth is not. According to Dumitrescu Hurlin panel causality results, it is seen that there is no causal relationship between CO2 emissions, economic growth and energy use. While there is a unidirectional causality from CO2 emissions to foreign direct investments, it has been determined that there is a bidirectional causality between trade openness and CO2 emissions. When the results are examined in general, this study provides important ideas about the determinants of CO2 emissions in the G8 countries.
