ARCADIS and UN-HABITAT Team up to Improve Urban Quality of Life

ARNHEM, Netherlands, March 24, 2010 - ARCADIS (EURONEXT: ARCAD), the international design, consulting,
engineering and management services company, and UN-HABITAT, the United
Nations agency for human settlements, launch today a three-year collaboration
aimed at a common goal: to improve the quality of life in rapidly growing
cities around the world. By becoming a main partner of UN-HABITAT, ARCADIS
will commit its staff members, expertise and skills to help bring the
UN-HABITAT mission forward. ARCADIS already supports UN-HABITAT with setting
up a program for the sustainable rebuilding of the cities of Haiti, which
were destroyed during the earthquake last January.

One of the biggest challenges of this century is the improvement of the
quality of life in the rapidly growing cities all over the world. The world
has entered the urban millennium as for the first time in human history more
than half of the world's population lives in cities. Almost one billion of
them live in slums and substandard housing. If nothing is done, this number
will double in the next thirty years. As one of the leading companies in the
world providing professional services to improve the quality of life of
people, ARCADIS is well positioned to support UN-HABITAT to address this
urgent challenge. ARCADIS' talents span the fields of infrastructure, water,
environment, buildings and urban planning at the highest levels.

There is a close fit between UN-HABITAT and ARCADIS as both organizations
focus on the improvement of the urban environment. Harrie Noy, CEO of ARCADIS
says: "Our skill set matches with the needs of UN-HABITAT, allowing us to
offer exactly the type of expertise and experience it needs. These can be put
to excellent use in helping UN-HABITAT meet the needs of the fast-growing
cities in the world. The fit between our two organizations is made even
better by the fact that UN-HABITAT is a global, accessible and above all
flexible and efficient organization that has a good reputation."

Drawing on the expertise of ARCADIS in the field of building, urban
planning, water management, infrastructure and environment the partnership
between UN-HABITAT and ARCADIS will focus on two activities. The first
activity is participation of ARCADIS employees in UN-HABITAT projects such as
the recovery program for Haiti where they bring in their expertise. A second
will be transferring expertise in urban planning and development by
organizing seminars for city officials from around the world, for example in
the field of climate change adaptation.

ARCADIS will also become a main sponsor of the World Urban Campaign, an
initiative from UN-HABITAT designed to raise public awareness and to address
the social, economic and environmental challenges of urbanization.

Anna Tibaijuka, Executive Director of UN-HABITAT explains the importance
of the partnership with ARCADIS: "UN-HABITAT operates all over the world and
there is an increasing demand for our services. The more we can share
innovation and expertise, the more effective we can be. ARCADIS is a very
important partner which is open to sharing its knowledge and spirit of
innovation with the rest of the world and we'd like to facilitate this
sharing process."

The cooperation of employees with different skills from different
countries in project teams, will also have a positive impact on ARCADIS. By
combining different efforts and resources throughout the company, this will
be the single largest commitment in the field of social responsibility of
ARCADIS. This shows the commitment of the company to improve the human
habitat.
