groundwater can be used directly or indirectly and any decline in its quality or quantity maynegatively impact the environment. through groundwater valuation, people are made aware of the fact thatgroundwater is not free of charge and therefore the significance of groundwater preservation is established. in this study, groundwater quality preservation value has been estimated for the city of ya...

Physical and intellectual access to heritage is shaped by conservation through a longterm, cyclic and symbiotic relationship of representation and intervention (or lack of it). This informs future use and representation. Value (which may be assigned for different reasons) makes heritage. All heritage is valued for varied reasons. Some argue that heritage has inherent value; this is not covered ...

Abstract High biodiversity tends to lead the public, including experts, towards one definite direction, namely conservation. Then came idea of need identify areas with high for Furthermore, any area must be conserved and should not cleared cultivation. However, after being protected, how use public welfare is done immediately, even never. In fact, many conservation have been damaged, some under...

This paper discusses a connection between scalar convex conservation laws and Pontryagin’s minimum principle. For flux functions for which an associated optimal control problem can be found, a minimum value solution of the conservation law is proposed. For scalar space-independent convex conservation laws such a control problem exists and the minimum value solution of the conservation law is eq...

BACKGROUND Developing effective conservation plans for multi-functional landscapes requires an accurate knowledge of the relative conservation value of different land-uses. A growing number of tropical ecologists have evaluated conservation value using the number (or proportion) of species that are unique to primary or old-growth forests. However, estimates of the conservation value of modified...
