Managed Aquifer Recharge:
A Global Perspective
Nienke Ansems

roundwater is an increasingly important resource
for human development, including domestic water
supply, irrigated agriculture and industry. In addition,
groundwater has an important environmental role in
sustaining rivers' baseflow, ecosystems and associated ecosystem
services. Groundwater is of strategic importance to achieve global
water and food security under a changing climate.
Managed Aquifer Recharge (MAR) is
considered an essential technique to meet
water demands for the future. As pressures
on freshwater resources increase globally
as a result of growing water demands,
urbanization, increased food production
and the necessity to preserve ecosystems,
MAR is expected to be increasingly relied
upon (Dillon et al. 2010). Given that MAR
can provide more effective, sustainable
and cost-efficient freshwater management
solutions as compared to aboveground
solutions, such as construction of surface
water dams or saltwater desalination
(Sprenger et al. 2017), one may wonder why it
is not yet implemented at a much larger scale.
MAR is still relatively unknown, and
decision-makers may wrongly perceive it as
costly and potentially complicated. So how
can we improve the global acceptance of
MAR to ensure that it becomes fully adopted
as an integral component of sustainable water
management strategies?

Five actions to increase
global acceptance of managed
aquifer recharge

1. Increase awareness on the benefits
of MAR
There is a need to increase awareness
amongst decision-makers, water resource
managers and water users on the benefits of

MAR and on the technical aspects of design,
implementation and maintenance. There are
initiatives, like the MAR Commission of the
International Association of Hydrogeologists
(IAH-MAR), that facilitate exchange of
information and raise awareness among
the water community. But to a large extent,
the knowledge still resides within a small
group of research institutes and groundwater
specialists. This is unfortunate, since MAR
could be applied as an integrated water
management strategy, and it presents
opportunities for conjunctive management
of surface water and groundwater resources.
For example, in semi-arid regions, seasonally
or intermittently, available excess water
can be captured and stored in aquifers. As
such, MAR can be applied to better balance
year-round water supply and to meet water
demands throughout the year.
2. Improve access to information on MAR
demonstration projects
Improved access to information on MAR
projects will help stakeholders to better
understand the benefits and to adopt MAR
on a larger scale. Demonstration projects will
provide confidence that MAR techniques can
contribute to sustainable water management
and will highlight how MAR applications
can be adapted to local situations. In 2016,
the Technical University of Dresden and the

International Groundwater Centre (IGRAC)
developed the MAR portal (http://marportal.
un-igrac.org). It comprises an interactive map
with detailed information on 1,200 existing
MAR sites around the world. These existing
schemes offer real-world and best-practice
examples that can be useful in planning
and implementing new projects. The portal,
which is in ongoing development, collates
the most up-to-date information on MAR
for dissemination.
3. Develop regional MAR suitability maps
MAR can be applied at different scales
and for different purposes. However,
aquifer characteristics must be suitable,
excess water available and local conditions
must be favorable. Developing regional
MAR suitability maps helps to identify
location(s) with the highest potential for
successful implementation. A structured
approach to the selection of sites minimizes
risks in terms of design, operation and
maintenance thereby improving efficiency
and economics of a MAR project.
Showcasing potentially suitable locations
for MAR can accelerate uptake.
