Local strategies to manage groundwater depletion under climate change scenarios—a case study: Hamedan-Bahar Plain (Iran)

Groundwater management in the state of Piauí (Brazil) on the climate change context

“…Hydrological modeling becomes fundamental for management as it enables the construction of scenarios, planning, and public policies that reflect the objectives and decision-making processes (Gorelick and Zheng, 2015). Hydrological modeling can be used in different ways: to calculate safe extraction levels (safe yield) (Sayed et al, 2020), different measures of resilience against climate change (Afruzi et al, 2021;Saadatpour et al, 2022), and the sensitivity of aquifer systems to climatic and hydrological variables (Pasta Cordeiro et al, 2021;Seidenfaden et al, 2022).…”

“…Even with the advancement of agricultural land (Figure 5C) and urban areas (Figure 5D), it is essential to protect recharge areas from both waterproofing and contamination processes. Furthermore, authors such as Afruzi et al (2021) and Saadatpour et al (2022) demonstrate that a reduction in the volume of water pumped or in the number of wells used brings benefits to the piezometric levels of the aquifers, even for the most pessimistic scenario (RCP8.5). Afruzi et al (2021) also emphasize that, for irrigation, it is important to develop techniques for the efficient use of water, the reduction of the irrigation area, and the promotion of rainfed agriculture.…”
