Plant communities associated with the agricultural landscape are gradually getting impoverished and even eradicated and replaced by poor species in many places of the world. A large number of studies are now available about the interactions between root and the soil system. However, influence of plants on aggregate stability remains to be a complex issue. The aim of this work was to determine the changes in the soil quality indicators that have developed at the rhizospheres under the selected weeds in the abandoned land. The results confirmed significant changes on bio-diversity of weed communities in a succession of over a decade. There were only 14 weed species in the abandoned field in the spring of 1998. The survey in the spring of 2008 confirmed the presence of 34 species. A decadal abandonment of the prime soil of the Mediterranean environment proved to increase the amount of the water stable aggregates and the mycorrhizal activity along with the accumulation of the organic and available nitrogen.

The final outcomes of the approach of the anthroscape, seeking to develop a powerful tool for use by the local communities/administrations and relevant bodies for a bottom to top approach, as a quantified entity, means to direct the future land and water use decisions to be taken at lower levels – as farm domains etc. – leading to the development of an ˵Anthroscape Land Quality Class″ map and the relevant ˵Ideal Land Use Patterns″ of the Seyhan Anthroscape. These two final products of quantification are sought to be capable in revealing the magnitude and the distribution of the degradation of the selected area, as well as allocating the ideal land use types given for the percentages of the distributions of land except their specific location. In this context, the downstream part of the map will show the abundant degradation arising via the intensive cultivation practices where the class stated in the map reveals the urgent need of an integrated SLWM Programme to revert the lower class C and D ALQCs to higher ALQCs to meet the requirements of the sustainable use of the land. Whereas, the higher ALQC land in the transition or upstream zone stands for higher resilience and lower input requirements to meet the ideal use of the land. The Net Primary Production (NPP) – The remainder of photosynthesis and respiration – which has significance in the global and regional carbon budgets and is a function of the standing biomass (an important component of the carbon cycle and a key indicator of ecosystem performance) was utilized via land cover and management to serve as a supplementary indicator of the Anthroscape and the Anthroscape Land Quality.
