is

in

constant

motion.

It

is

part

of

a

cycle

–

one

that

ignores

all

borders

created

by

humans.

As

such,

it

is

a

commongood,whichrequirescommonmanagement,ifthismanagementisto

bebotheffectiveandrelevant.Forwhathappensupstream

always

has

an

impact

downstream:

extracting

water

from

rivers

or

aquifers

directly

concerns

all

the

populationsthat

depend

on

them.For

this

reason,

water

is

an

essential

component

of

international

cooperation.

But

how

can

we

ensure

the

success

of

thepartnerships

and

cooperative

arrangements

on

which

its

sustainable

management

depends?

That

is

the

question

askedby

this

United

Nations

World

Water

Development

Report,

coordinated

by

UNESCO

on

behalf

of

the

UN-Water

family.Successful

initiatives

often

apply

a

number

of

principles,

which

are

presented

in

this

report

–

whether

this

means

theinclusion

of

all

communities,

like

indigenous

peoples

and

women,

or

the

adoption

of

an

interdisciplinary

approach.Pooling

expertise

and

perspectives

leads

to

more

relevant

and

efficient

management

–

as

seen

in

the

impressive

ClimateRisk

Informed

Decision

Analysis

tool,

which

helps

identify

climate

adaptation

actions,

or

in

the

mapping

of

the

StamprietAquifer,

shared

by

Botswana,

Namibia

and

South

Africa.UNESCO

seeks

to

implement

these

principles

on

a

daily

basis,

for

water

is

an

important

area

of

action

for

our

Organization.Over

the

past

50

years,

we

have

developed

two

major

programmes:

our

Intergovernmental

Hydrological

Programme,

withits

169

national

committees

and

18flagship

initiatives,

and

our

World

Water

Assessment

Programme,

both

of

which

haveallowed

us

to

develop

an

impressive

network

of
