Managed aquifer recharge: the solution for water shortages in the Fergana Valley por Karimov, Akmal A., Smakhtin, Vladimir U., Mavlonov, A., Borisov, V., Gracheva, I., Miryusupov, F., Djumanov, J., Khamzina, T., Ibragimov, R., Abdurahmanov, Botir

“…The shift of the key upstream reservoir on the Naryn River, main tributary of the Syrdarya River, from irrigation to hydropower generation reduced available water for irrigation in the summer and created excessive flows in the winter. The downstream reservoirs do not have free capacities for storing the excessive winter flows. …”

Climate impact of bioH2 production from biogas using CO2 mineralization for carbon capture and storage por Harðardóttir, Hera

“…Global energy demand will continue to rise in the future, resulting in increased carbon emissions. Hydrogen (H2) could potentially decarbonize energy systems and replace fossil fuels. …”

Future climate change scenarios in Central America at high spatial resolution por Imbach, Pablo, Chou, Sin Chan, Lyra, André, Rodrigues, Daniela, Rodríguez, Daniel, Latinovic, Dragan, Siqueira, Gracielle, Silva, Adan, Garofolo, Lucas, Georgiou, Selena

“…The objective of this work is to assess the downscaling projections of climate change over Central America at 8-km resolution using the Eta Regional Climate Model, driven by the HadGEM2-ES simulations of RCP4.5 emission scenario. The narrow characteristic of continent supports the use of numerical simulations at very high-horizontal resolution. …”
