abstract = "Coastal water resources are a worldwide key socio-environmental
issue considering the increasing concentration of population in
these areas. Here, we propose an integrative transdisciplinary
approach of water resource, water management and water access in
Recife (NE Brazil). The present-day water situation is
conceptualized as an imbricated multi-layered system: a
multi-layered water resource, managed by a multi-layered
governance system and used by a multi-layered social population.
This allows identifying processes of quantitative, qualitative,
and sanitary conflicts between governance and population
strategies regarding water supply, as well as the institutional
and individual denials of these conflicts. Based on this model, we
anticipate future water-related problematic fates. Concerning the
water resource system, the rapid groundwater level decrease due to
unsustainable water predatory strategies, and the very low
recharge rate have drastically modified the aquifer system
functioning, inducing hydraulic connection between shallow
groundwater (contaminated and locally salty) and deep ones (mostly
fresh, with local inherited salinity), threatening the deep
strategic water resource. Concerning the water governance system,
the investments to increase the capacity storage of surface water,
the water regulation agencies and the public/private partnership
should shortly improve the water supply and wastewater issue.
Nevertheless, the water situation will remain highly fragile due
to the expected water demand increase, the precipitation decrease
and the sea-level increase. Concerning the water access system,
the population variably perceives these current and further
effects and the possible mitigation policies, and develops
alternative individual strategies. Authorities, policymakers and
water managers will have to implement a well-balanced water
governance, taking into account the specificities of the PPP,
public and private groundwater users, and with a strong political
willingness for a sustainable water management to ensure water
supply for all the population. In other words, an anticipatory and
integrated vision is necessary to reduce the discrepancies in this
complex system.",
