Soil provides innumerable valuable ecosystem services, such as the production of food and the direct support of wildlife, by ensuring the availability of adequate habitat. However, unsustainable human activities are resulting in degradation of soils worldwide. Hence, it is of utmost importance to raise awareness about this often-overlooked environmental issue. This article presents an inquiry-based activity that challenges students to assess the ecological quality of soil in the surroundings of their classroom. Plus, students and teachers are invited to become citizen scientists by sharing their data with researchers, thus contributing to a future endeavor to map soil quality through broad geographic ranges.

Environment Sustainability

Sustained development is the target of almost every modern policy dealing with the aquatic environment. Sustainability is focused on human life, but also on the ecological quality of our environment. Both aspects are essential for life on earth. The ecological quality of aquatic systems can be expressed by biotic and abiotic parameters. Monitoring and research give information about these parameters and a comparison with the targets brings us to the necessity of supplementary policy-measures. Human activities are considered to be the cause of the environmental problems. All kinds of social and economical activities influence the water bodies. Reaching the goals is only possible if human influence on environment is changed or reduced. Within a catchment area, relations could be laid between human activities and ecological problems in the reception areas. Policy analysis is especially looking for the most efficient way to remove the bottlenecks. For an effective policy analysis in river catchment areas the following elements are essential: – quantitative data; monitoring programs have to consider more than ever the ecological aspects of policy analysis; – the determination of target values (probably by means of laboratory experiments); - knowledge about the factors causing violation of the targets; – an inventory of measures for influencing the existing or future situation; – sufficient knowledge about the relation between the measures and (i) the ecological parameters and (ii) the social and economical activities in society; – a policy analysis for defining future policies; All of these studies will generate many data; to present these in a clear and succinct manner is one of the goals of the project “The Aquatic Outlook”.

Abstract The Shiyang River basin is a typical inland arid region and one of the most fragile and sensitive areas of terrestrial ecosystems in China, and it is important to understand its ecological changes in a timely and accurate manner. This article selects the Shiyang River basin forest as the research area and uses Google Earth Engine (GEE) to evaluate and monitor the ecological environment quality of the Shiyang River basin from 1990 to 2020. The geographical detector model (GDM) was also used to analyse the sensitivity of the forest ecological environment to three natural factors: elevation, temperature and altitude. The results showed that the ecological quality of the natural forest is significantly better than that of the man-made forest area, and the ecological quality grade is higher. The forest change area RSEI has a large annual variation in ecological quality and is vulnerable to external factors. Among the influencing natural factors, the sensitive factors of precipitation and altitude are both greater than 84%. The temperature sensitivity of natural forests is stronger than that of man-made forests, ranging from 66% to 92% overall.
