Resumen
Descripción
For centuries, management of
freshwater resources has focused on monitoring and managing
water quantity to ensure supplies for domestic,
agricultural, and industrial use and to mitigate the
potential effects of floods and droughts. However, the
quantity of water is inextricably linked to its quality, yet
much less attention has been paid to the latter. Every human
use of water, and the aquatic ecosystem itself, has minimum
requirements for water quality. At a national scale,
managing water quantity and water quality have often been
the remit of different government agencies with limited
sharing of information. This report summarizes key aspects
and presents a framework to assist water accounting teams to
evaluate the needs for incorporating water quality
monitoring into their operations. The framework presented in
this report introduces a step-by-step approach to defining
scope and objectives and to identifying data needs and
monitoring approaches for data collection and computation of
loads. Data analysis and presentation options are also
explored. Implementation of the framework is illustrated
with three different scenarios of different scope and scale
of water accounting activities: an irrigation scheme, a
river basin, and a reservoir. The scenarios illustrate
suggested locations for monitoring, relevant water quality
parameters for inclusion, the time frame for data
collection, and interpretation of the results.
