Environments (ISSN 2076-3298) is an international, cross-disciplinary, open access journal focusing on advances, issues and challenges related to environmental systems. Our aim is to provide an open space for scientists and engineers to publish and discuss their experimental, theoretical, and novel practical results in a variety of areas, with particular focus on shared responsibility and sustainable approaches to resource use and ecosystem management. Key research areas include environmental conservation; environmental technologies; ecosystems and ecosystem services; risk assessment; monitoring and modeling of environmental systems; policymaking and governance for stakeholder engagement and decision support. The biosphere, as the shared habitat of all species, including humans, requires a full understanding and appropriate environmental policymaking to ensure safe interactions, prevent biodiversity loss, and promote long-term sustainability. There is no restriction on the maximum length in words of submissions. The full experimental details must be provided with the basic QA so that the results can be reproduced. For details on the calculation or experimental procedure that cannot be fully described in the main manuscript (Word/LaTeX format), electronic files and software can be deposited as supplementary electronic material.
