Vakanjac The word “exploitation” originates from the French exploitation and exploiter, meaning making full use and benefiting from something in the best possible manner. In the broader sense, the word can imply taking advantage of other persons’ labor by owner(s) of capital; manipulation; use and abuse of natural resources, assets and spirituality; mistreatment of people as human beings (human trafficking, certain types of sects, etc.), and the like. The paper discusses in detail the exploitation of natural resources, in the specific case of sand and gravel from the banks and/or channels of large rivers. The channels and banks of large rivers, especially along their lower courses, are significant natural sources of sand and gravel. Their exploitation is of overriding importance for the construction industry. However, uncontrolled and illegal over-exploitation of sand and gravel has a large impact on the pre-existing balance of the native biocenoses and, in addition, has an adverse effect on surface water and groundwater regimes and the stability of dykes, bridges, revetments and other hydraulic structures, while heavy trucks demolish infrastructure. Abandoned pits become ponds and swamps, used for illegal dumping of waste, which increases the populations of rodents, mosquitoes, frogs, etc. Both abandoned and active machinery and vehicles leave behind fuel, oil and other pollutants, which can easily reach groundwater resources and permanently damage their good quality. On the other hand, deepening of river channels through gravel and sand excavation permanently lowers river stages. This consequently affects water levels of wells which are in hydrodynamic contact with river water. In some cases the water table has dropped to below the bottom of wells, causing them to dry out. In view of the fact that the exploitation of sand and gravel has multiple adverse consequences, the question is to what extent it can proceed with minimized consequences, so as not to disturb the pre-existing balance. conferenceObject 57 62 Zbornik radova sa nacionalne konferencije sa međunarodnim učešćem: Ekoremedijacija i ekonomska valorizacija vodnih resursa - modeli i primena (editor Rikalović M.)
