<strong>Water</strong> <strong>as</strong> <strong>Leverage</strong> <strong>for</strong> Resilient Cities Asia<br />

<strong>Setting</strong> <strong>the</strong> Scene <strong>for</strong> a Call <strong>for</strong> Action<br />

Content<br />

There are<br />

5 recurring<br />

perspectives<br />

that link<br />

water issues<br />

and urban<br />

dynamics in<br />

a successful<br />

way<br />

Improving The Old<br />

with The New<br />

<strong>Water</strong> issues, failing structures and<br />

demographic growth put pressure<br />

on many obsolete urban are<strong>as</strong>.<br />

This creates a need <strong>for</strong> large-scale<br />

investments in water management.<br />

But smart injections can restructure<br />

<strong>the</strong> water system on <strong>the</strong> scale of<br />

<strong>the</strong> entire city, without renewing it<br />

all: <strong>for</strong> example, when new urban<br />

development gives rise to public<br />

and private investments upstream,<br />

<strong>the</strong>se will automati<strong>call</strong>y have a<br />

positive impact on water quality or<br />

quantity in <strong>the</strong> downstream are<strong>as</strong> of<br />

a city.<br />

Incremental Upgrading<br />

Underprivileged population groups are usually<br />

driven towards <strong>the</strong> most precarious urban<br />

are<strong>as</strong>, often close to major water bodies. These<br />

neighborhoods perpetuate a cycle between<br />

dependence on water <strong>for</strong> economic activities,<br />

continuous natural threats and ecological<br />

degradation. Instead of setting up large-scale,<br />

imposed relocation or redevelopment projects to<br />

clear water structures, gradual and even co-created<br />

adaptations to <strong>the</strong> urban and water infr<strong>as</strong>tructure –<br />

such <strong>as</strong> collective sewerage provision or relocation<br />

within <strong>the</strong> community – could facilitate major<br />

positive impacts on <strong>the</strong> surrounding urban living<br />

and ecological conditions.<br />

History is The Future<br />

Urban settlements in lowlying<br />

are<strong>as</strong> or around complex<br />

river systems usually had to<br />

develop a secure system of<br />

me<strong>as</strong>ures <strong>for</strong> water protection<br />

or storage throughout history.<br />

Due to population pressure,<br />

however, <strong>the</strong>se old inventive<br />

water structures are often<br />

incre<strong>as</strong>ingly abandoned,<br />

disused or considered only <strong>as</strong><br />

cultural heritage.<br />

(Re)structuring current<br />

and future urbanization by<br />

recovering this historical water<br />

system and reactivating it with<br />

contemporary techniques can<br />

contribute to <strong>the</strong> resilience<br />

<strong>the</strong>se water cities once had.<br />

Living with <strong>Water</strong><br />

Urbanization in low-lying are<strong>as</strong><br />

such <strong>as</strong> wetlands or delt<strong>as</strong><br />

h<strong>as</strong> to deal with water issues<br />

in an almost amphibious way.<br />

Periods of too much or too<br />

little water result in a complex<br />

multi-dimensional paradox of<br />

excess and shortage, usually<br />

leading to heavy drainage<br />

or aquifer overexploitation,<br />

setting in motion a<br />

rollerco<strong>as</strong>ter of problems of<br />

<strong>the</strong>ir own. Integrated, systemic<br />

water sensitivity strategies and<br />

typologies that store, delay,<br />

retain or re-use <strong>the</strong> available<br />

water can help to unravel <strong>the</strong><br />

paradox and balance <strong>the</strong> city’s<br />

water issues.<br />

Adapt to Mitigate<br />

<strong>Water</strong> problems in urbanized are<strong>as</strong> are usually<br />

mitigated: protection me<strong>as</strong>ures prevent <strong>the</strong> worst<br />

damage and keep <strong>the</strong> city’s livelihood safe. But<br />

we could also adapt to <strong>the</strong> problems we face by<br />

generating solutions that start from <strong>the</strong> systemic<br />

logic of changing dynamics – such <strong>as</strong> sea level rise,<br />

storm incre<strong>as</strong>e or fl<strong>as</strong>h floods. Literally creating<br />

room <strong>for</strong> water bodies to flood safely could also<br />

generate or streng<strong>the</strong>n adaptive economies and<br />

improve <strong>the</strong> quality of <strong>the</strong> immediate urbanized<br />

surroundings.<br />
