Green Designs in Hydraulics—Construction Infrastructures for Safe Agricultural Tourism and Sustainable Sports Tourism Facilities Mitigating Risks of Tourism in Crisis at Post COVID-19 Era

Nowadays, global and local tourism sector is in crisis at post-COVID-19 era. This study presents efficient infrastructure sustainable design facilities that could provide solutions for safe facilities and mobility sustainable services supporting alternative types of tourism like agritourism and sports tourism at mountainous places or close to coasts, mitigating associated risks. A useful roadmap is presented for efficient green circular economy for all in the society should adopt particular effective construction green designs with the proper utilization of green renewable resources and clean technologies support that promote public health protection, avoiding chemical toxic pollutants to the environment. In this way, new opportunities are created for an integrated health policy using proper economic instruments that achieve investments at regional level, generating effective construction design solutions for tourism services, including safe green transportation infrastructures, efficient green hydraulic projects, safe green building facilities with effective hydrogeotechnical designs for public health protection in climate change, energy crisis, food security and global economic crisis at postCOVID-19 era. Hence, the concept of green circular economy (CE) has received increasing attention between policymakers and stakeholders worldwide. This work aims to present the importance of useful geo-environmental designs within green construction facilities supporting biofuels and renewable resources production alternative types of tourism. Useful project management geoinformation ICT's, IoT's, web g.i.s solutions are necessary that include efficient hydraulic designs, sustainable development, monitoring schemes, associated green tourism infrastructure designs, safe green transportation systems, efficient hydro-geotechnical projects, robust irrigation-drainage designs and green effective logistics in particular tourism services for environmental, public health protection. Moreover, in order to achieve competitive experiencing, safe green travel destinations are necessary protecting public health that are supported by innovative construction designs, reclamation projects for enhancing associative activities within sport tourism, agritourism, cultural sites, ecological places, archaeological geographies, traditional recipes, drinks and heritage monuments. The latter could be combined with proper e-learning, monitoring schemes, training web utilities for stakeholders at sustainable tourism infrastructures and vocational educational useful training utilities.
