HUMAN WELLBEING IN CITIES
Villagers carry pitchers filled with drinking water after visiting a well at Meni village in the western Indian state of Gujarat (Reuters)
Capacity of ecosystems
e.g. half of cities with more than
100.000 inhabitants are located in
water scarce basins
(Srinivasan et al. 2012, Richter el al 2013)
Adequate infrastructural &
institutional capacity
(Kayaga et al. 2013, Lieberherr & Truffer 2015)
Adaptation & Integration(Cortner and Moote 1994, Ward 1995, Gleick 2000, Pahl-Wostl et al 2002, 2007, 2011)
Participatory management and collaborative decision-making;
Addressing problem sources not effects;
Changing human behavior through “soft” measures;
Open & shared information sources (linking science & decision-making);
Embedded in iterative learning cycles;
Adaptation & Integration paradigm
Key challenge to real-life implementation
Linking diverse actors and knowledge systems, across management
levels, sectors, and institutional boundaries.
(Folke et al 2005, Parker and Corona 2012, Kowalski & Jenkins 2015)
Spatial considerations
THREE KEY ROLES
i linking ecosystem service production and benefit areas;
ii bridging spatial scales ranging (watershed to household);
iii adopting ES-based responses to water vulnerability.

• Set of activities put in place by any organization/individual that seeks to mediate between knowledge and action
(Cash et al 2003)
KNOWLEDGE ACTION
Attributes
• Participation
• Accountability
• “Boundary object”
Criteria
• Credibility
• Saliency
• Legitimacy
Boundary Work
• Active management of tension at the interface between stakeholders with differing views on relevant knowledge
(Clark et al. 2011)
“Boundary Work”: Highly context-specific

Investigating boundary work practices
THREE RESEARCH QUESTIONS
i. Type of barriers for transfer of knowledge into action?
ii. Boundary work activities put in place?
iii. Effectiveness of boundary work?

Findings
Context: knowledge Use and Source;
‘enlightenment’, ‘decision-support’, ‘negotiation-support’;
Boundary work: a dynamic process, not a single-time achievement;
“Contextual” & “contingent” factors, and relative influence (power) of actors.

METHODOLOGY
Part 1Investigation of the two case studies
WUM-based interview with head of Asmara Utility
•11 questions - general information• 23 questions for each attributes
• 7 ranking questions
Part 2WUM-based questionnaire
For each case study •3 senior mangers
•1 informed scientist
• “All-inclusive” perspective of institutions as “rules-and-roles” ;
• Institutional capacity as “capacity to continuously generate a minimum level and
quality of valued outputs, and to prioritize learning” ;
• Strong theoretical basis + application-oriented.
Initial Basic Proactive Flexible Progressive
• Integrative, mutually exclusive, collectively exhaustive;
• 23 attributes
• 5 maturity levels

Influence Hannover Water Utility Asmara Water Utility
Policy, legal,
regulatory, and
political environment
Utility has predictive capabilities, and carries
out risk/opportunities assessment and
management; continuously adaptive to the
external environment in near real-time.
Leadership passively interested in factors in the
external environment, and reacts to them rather than
strategically influencing them.
Managerial autonomy Utility has full autonomy with respect to all
managerial, operational and financial
decisions.
There is limited managerial and operational
autonomy.
External
accountability
Utility has a balanced accountability
framework.
External accountability mechanisms in place but not
effective.
Partnerships and
networks
Partnerships are integrated within business
processes.
Partnerships and networks may be initiated by
individual staff. Supplier communications are limited
to tendering, order placement or problem resolution.
Corporate image The results of the corporate image scans are
integrated into the performance/incentive
management system for staff.
Leadership is aware of the importance of corporate
image; however, it is not monitored or evaluated in a
consistent & systematic manner.
Findings
• Hannover Water Utility = Level 5 “Progressive”
• Asmara Water Utility = Level 2 “Basic”
• Capacity dimension “ INFLUENCE ”
Main research outputs
• Paper 1: “Exploring practices of effective boundary work in watershed management for ecosystem
services”, submitted to “Ecology & Society”;
• Paper 2: “Designing, and assessing watershed investments: An operative approach based on ecosystem
services”, submitted to “Environmental Impact Assessment Review”;
• Paper 3: “Evaluating institutional capacity of a water utility: An empirical application of the Water Utility
Maturity Model”, to be submitted to “Water utilities policy;

RIOS Approach
• Need for operative methodologies to support design, and implementation of
watershed investments, in a context of adaptive management. (e.g. Tallis et al, 2015, Schultz et al. 2015).
