Soil plays a critical role in mitigating the effects of climate change, increasing farm productivity and food security. Therefore, a healthy environment and soil health are the necessity of sustainability and prosperity of society. Land degradation leads to very severe damages on the Earth. Soil erosion is one of the most destructive land degradation processes also concerning ecosystem services. Soil provides some of the following ecosystem services: soil acts as a water filter and a growing medium; provides habitat for billions of organisms, contributing to biodiversity; regulates the quantity of eroded sediment reaching the stream network, maintaining soil and water quality and reservoir functions. To better preserve ecosystems in line with economic development, the Natural Capital Project (Stanford University) is developing models that quantify and map the values of environmental services. InVEST (Integrated Valuation of Ecosystem Services and Tradeoffs) is a group of models used to map and value the goods and services from nature. It helps explore how changes in ecosystems can lead to changes in the flows of many different benefits to people. In order to map overland sediment generation and delivery to the stream, the InVEST Sediment Delivery Ratio (SDR) model was used in the Topciderska River basin (Belgrade, Serbia). This is of particular interest for reservoir management and instream water quality, both of which may be economically valued. Assessment of soil ecosystem services is valued using the Cost/Benefit analysis, as well as Total Economic Value (TEV) which has direct and indirect impacts on humankind. Evaluating ecosystem services in monetary terms is very complex, but also a useful tool in the decision-making system. Due to its specificity and complexity, evaluation should be based on criteria of potential ecosystem efficiency, and not on value calculations. Thus, the services that soil provides to mankind are defined through the services of supply, regulation, cultural services, ancillary services, health, safety, energy security... This, combined with socio-economic and law and policy analysis gives a full set of information to decision-makers helping them to successfully manage and deliver sustainable ecosystems."
