Influence of Fall Height Setting on Drop Weight Tested Polypropylene and its Crack Growing

Abstract: Improving a rehabilitation of the entire agricultural landscape is an impellent necessity, because it represents the most important possibility for man to recover our Earth: especially after the decrease of ecological efficiency due to the agrarian industrialization and the expanse of urbanization. To strike this goal both ecological and economical criteria are needed, so the concept of “Ecosystem Services” may give a crucial contribution, confirming the renewed role of the farmer in environmental recovery. But these Services are linked with conventional ecology and consequently the “Ecosystem Services” present some limits. The new discipline of Landscape Bionomics (LB) proposes principles and methods influencing even the “Ecosystem Services” and the measures of their ecological and economical value. After a synthesis of LB and its ability to evaluate the mentioned decrease of ecological efficiency through the concepts of Transformation Deficit (TD), Human Habitat (HH), Standard Habitat per capita (SH), Protective Landscape Apparatus (PRT), Biological Territorial Capacity of Vegetation (BTC), the equivalence of Bionomics Costs/Economics Costs or Bionomic Values/Economic Values is more deeply defined. The values of agrarian and forest lots (referred to 2010-2015 values of Lombardy Italian region), become respectively 113 and 270 €/m2. These values can change in relation to the bionomic quality of the lot. So, a more fitting measure of environmental damage can help to better defend agrarian landscapes.
