28 practically oriented cross sectoral infrastructure projects identified in the

Nexus partner cities amounting to an estimated investment volume of EUR

300 million.

• waste to energy & water, recovery of valuables,

• waste water to energy, nutrients and reuse of water,

• replacement of outworn water pumps through energy efficient pumps for water supply

• reduction of water losses through leakage detection and

• energy efficiency of buildings through thermo-technical retrofitting and

renewable energy application.

“Land is gold”, hence innovative technologies improving the resilience of

cities have to economize on land consumption as cities are running out of land.

RESULTS

• The Nexus infrastructure projects are seen in the light of a circular

economy paying attention to the separation of mass flows in order to

reuse scarce resources such as water and energy.

• Decision makers have been made aware that waste and waste water are

not a burden but an opportunity to create additional income.

• The introduced technologies reflect decentralized approaches, however,

being built up as modular systems, they can also be integrated into existing

grid systems.

• Respective framework conditions are required to promote resource

efficiency (the urban nexus); cross sectoral policies, consumption-oriented

and cost covering tariffs, incentives to economize on water and energy

consumption (behavioural change).

• Awareness creation within coordination/planning ministries and

donors required.

RESULTS

• In national-subnational-local dialogue forums questions of mandates,

technology solutions and decentralization approaches of the Municipalities

are discussed regularly and have led to improved mutual understanding in

the framework of vertical integration.

• Horizontal integration promoting inter-communal cooperation in

particular with regards to infrastructure projects requiring economies of scale

are increasingly emerging in the area of solid waste management.

• Peer-to-peer learning has led to a better mutual understanding of shared

problems and solutions always requiring a tailor-made approach.

• Empowerment of cities as key drivers of development by decentralization

of national competences and financial resources.

“Smart cities”

The concept of “smart cities” requires a multi sectoral approach integrating

different infrastructure systems (integrated planning / Nexus approach) to

achieve:

• more resilience,

• climatic adaptation,

• energy- and resource efficiency,

• e-mobility,

• reduced costs by using synergy potentials,

• efficient and transparent administration and

• public consultation.

It is about optimizing synergies between the sectors, identify inter-linkages and

economize on the use of water, energy and land.
