t          reasure in the clouds
           Alvaro Luna

          Montane cloud forests are essential to the economies and
          livelihoods of the northern cities and communities of South
          America, supplying unpolluted fresh water for both people
and wildlife. Found from 1500 to 3000m in altitude along and be-
tween the eastern and western slopes of the Andes, they add to rain-
fall by intercepting moisture from clouds – a service which becomes
absolutely crucial during the dry season.
   Some cloud forests in the northern Andean region are protected
for their watershed values, but many are not, existing as islands of
forest amid farmland and exploited for their firewood, timber and
medicinal plants.
   These forests are also among the most biologically diverse eco-

moisture input to the forest. The resulting deforestation and frag-

system services including the provision of clean water, and of

   The Tropical Montane Cloud Forest Initiative was launched in
1999 by IUCN, WWF, UNEP-WCMC, the IUCN Netherlands Com-
mittee and several other partners. In 2002 it began work on a project
to maintain the unique watershed functions and biodiversity of the
northern Andean cloud forests.
   The project will promote the development of cloud forest con-
servation strategies and the strengthening of protected areas. It
will field-test new approaches to conservation such as payment for
environmental service schemes, forest landscape restoration, and
improved livestock management, and will oversee the creation of
an Andean cloud forest network and information system. It will
benefit from the technical support of its many international part-
ners, and be implemented by national partners in each of the five
countries of the northern Andes – Venezuela, Colombia, Ecuador,
Peru and Bolivia – as well as through regional mechanisms.
                                            zycnzj.com/http://www.zycnzj.com/
   The key to the project’s success will lie in its ability to build on
the large number of existing initiatives and partnerships already
operating in the region, and on the common interest of a wide and
varied roster of stakeholders, all of whom depend on the resources
and services of these remarkable ecosystems.

controlling floods, draining wetlands,

disposal, and daily water needs, so that
most of the Earth’s accessible fresh wa-

         Agriculture is arguably the pre-
         dominant influence on the
         Earth’s land surface. While only
about 30% of the total comprises agri-
culture-dominated landscapes or mosa-

agriculture-induced change.
   Indisputably, the major cause of
wetland loss around the world is drain-

of the world’s wetlands have already
been destroyed, and up to 60–70% in Eu-

c           alling all sectors!
            Peter B. Spillett

        The 3 rd World Water Forum in
        Kyoto was notable for organized
        protests against the role of the
private sector in water management.
This is ironic when you consider that
private sector involvement represents
less than 5% of the global water market.
Further, the challenge to meet the mil-
lennium goals on access to clean water
and public sanitation will require huge
resources and innovative thinking from
all sectors of society, including the
private sector.
   Many people confuse public-private
partnership (PPP) with full blown priva-
tization of water, including ownership of
the assets. In fact PPP represents sev-

 has largely been technology-driven and
 focused on engineering solutions. It has
 tended to ignore the social context of
 resource use, particularly the differing
 roles of women and men, poor and rich
 communities, and minority and major-

    Moreover, it has failed to value or

 WATER AND BIODIVERSITY

                Will Darwall

          Our new century presents a criti-
          cal challenge to the world com-
          munity: to provide safe drinking
water and sanitation for all. Construc-
tion of the inland water systems required
to meet this challenge, along with the
hydroelectric facilities needed to power
economic growth, can have severe im-
plications for freshwater biodiversity.
    Many communities depend on fresh-
water species for their basic needs. This
fact of local life requires much greater in-
tegration of biodiversity considerations

waters. But so far the international

         Convincing people who use land
         and water resources of the value
         of longer-term, strategic coastal
planning and scientific analysis is not
always easy. Nor is training researchers
to understand the short-term needs of
farmers, fishers or business owners.

a            dapting to uncertainty
             Brett Orlando

         If I were to write what we know
         for certain about the future im-
         pact of climate change, it would
make a very fast read.
   Scientists say we can generally expect
increasing instability of water and at-
mospheric cycles and more intense cli-
mate fluctuations. What are considered
extreme events today are likely to be to-
morrow’s norm. And it appears that the
water crisis faced by people in many
parts of the world today is destined to
get even worse.
   We can already see many of the signs.
Melting glaciers, thawing permafrost
and changing rainfall patterns are caus-




                                                                                                                                NASA
ing widespread damage, as the recent
floods in regions as far apart as China,
Europe and Southern Africa have
shown. How much change we experi-
ence depends in part on how much we
reduce carbon dioxide emissions, the
main culprit of climate change.
   This is no longer a time of certainty.
When even the experts are not sure of
the magnitude and rate of climate
change, all we can do is ‘prepare to
adapt’ to whatever the future brings. For
that we need coalitions of politicians,
scientists, managers and civil society to
assess risks and identify responses.
