Biodiversity Indexes: Value and Evaluation Purposes

The Value of Biodiversity

The Value of Biodiversity

Glossary Accounting prices Accounting or shadow prices are measures of the social opportunity cost of resource use. The accounting price of a resource is the increase in social wellbeing that would be enjoyed if a unit more of the resource was made available at no cost. Ecological functions The combinations of ecosystem component and ecosystem processes that enable ecosystems to support primary...

Optimal Encodings and Indexes for Nearest Larger Value Problems

Given a d-dimensional array, for any integer d > 0, the nearest larger value (NLV) query returns the position of the element which is closest, in L1 distance, to the query position, and is larger than the element at the query position. We consider the problem of preprocessing a given array, to construct a data structure that can answer NLV queries efficiently. In the 2-D case, given an n × n ar...

Bioprospecting: Creating a Value for Biodiversity

Bioprospecting is the exploration of biological material for commercially valuable genetic and biochemical properties (Reid et al., 1993). This chapter will focus on the search for activities that could form the basis of new pharmaceuticals. Historically, most of the active ingredients in medicines have been natural products (Sneader, 1996), and natural products continue to form a productive so...

Evaluation and mapping of groundwater quality for rigation and drinking purposes in Kuhdasht region, Iran

Preservation of water quality, particularly in areas with inadequate water resources is considered as one of the principles of planning in integrated water management. In Kuhdasht, a region at the west of Iran, groundwater and spring water resources are the major contributors of drinking and irrigation water supply. The aim of this study was to determine the suitability and mapping of springs a...
