The La Plata
River Basin
The aim of this project is to apply a systematic and integrated approach to water
management in a vast basin which has been relentlessly exploited for the past
several decades for a single major asset - energy production, and which has never
benefited from the multilateral cooperation of its five basin states. Harnessing
the energy potential of the La Plata basin is credited with bringing the states
of the region together, usually bilaterally for the purpose of particular hydropower
projects, but it has also created conflicts and serious environmental and social
problems which must also be resolved through cooperation. By adopting a territorial
approach, this project intends to forge improved relationships not only between
different layers of decision-making and the public within and across state borders,
but also in order to reconcile the needs of human society and the natural environment.
Activities will focus on identifying the causes of the waterrelated conflicts
both latent and already apparent in the basin and conducting pilot investigations
in one large sub-region and concerning five specific conflicting issues. The findings
and recommendations of the pilot projects will be translated into proposals for
the transformation of water management strategies across the basin, particularly
regarding the management of existing, and the evaluation and construction of new,
large interstate hydropower projects.

This project proposal was prepared by Green Cross Argentina, with the consultation
of experts at the University of Buenos Aires, and in other basin states. Green
Cross Argentina has been active in integrated water management projects for several
years, most notably regarding the environmental and social effects of the Yacyreta
Dam. GC Argentina will be the manager of the La Plata basin sub-project, with
the close collaboration of Green Cross offices in Bolivia and Brazil and other
institutes and organisations in the basin. | Background
The La Plata
Basin is the fifth largest in the world and covers approximately 17% of the total
continental surface of South America, including the south of Brazil, southeast
Bolivia, Uruguay, Paraguay and the northeast of Argentina. The main rivers, the
catchments of which form the basin, are the Parana, Tieté, Iguazu, Uruguay,
Paraguay, Pilcomayo, Bermejo and Río de la Plata. The total territory of
almost 3,000,000 km2 contains a huge variety of natural resources and ecosystems.
Several very large hydropower projects have already been constructed in the Basin
and as many others are being planned. The Plata Basin constitutes a zone of great
potential for the exploitation of natural resources, making interstate cooperation,
transparency, environmental protection and the participation of all sectors of
society in decision-making all the more necessary. Climate
has always been extremely important. The large area drained by the La Plata's
hydrographic system extends from the subequatorial zone, through tropical zones,
towards the temperate regions; precipitation varies widely from 3,000 mm a year
in Carambú (Brazil) and Puerto Bertoni (Paraguay), to 2,000 mm a year in
Orán (Argentina), to 840 or 763 in Río Cuarto (Argentina). This
territory is the most vital in the MERCOSUR region and the big cities of Buenos
Aires and San Paulo are both located there. Because of this, human pressure on
ecosystems, and especially on water as an energy source, is very strong. Over
70% of the combined GDP of the five basin states is produced in the basin, and
50% of the total population live there. The basin also boasts the most important
wetland area in the world, the Pantanal, and the largest hydroelectric plant in
the world, the Itaipu. The
relationships between Argentina, Brazil and Paraguay have steadily evolved towards
increasing cooperation since 1979, when disputes over the use of the Rio de la
Plata basin were first settled. The incentive for resolving these disputes was
the common desire to harness the huge hydro-power potential of the basin, which
resulted in bilateral agreements between Brazil and Paraguay, and Argentina and
Paraguay for the creation of the Itaipu and Yacyreta dams, respectively. Cooperation
over hydropower has been credited for encouraging the development of economic
integration, cooperation over defence matters and agreements on ensuring that
South America remains a nuclear free continent. However, these top-level agreements
for the sake of national and regional development were made with little involvement
or concern for the lives of the local people who would be effected, or the environment,
and the Itaipu and Yacyreta projects have left a legacy of corruption and failure
to compensate for environmental damage, or disrupted lives. Water management may
have enhanced regional cooperation and stability at the state level, but the schemes
have created new conflicts between effected peoples, governments and the authorities
responsible for the dams. The benefits from these cooperative schemes have yet
to be felt by many of the people who were most effected by them.
As more major hydropower projects are planned, to meet the growing financial and
energy needs of the basin states, there is a unique opportunity to avoid repeating
the mistakes of previous decades by approaching water resources management in
a democratic and integrated manner. Desciption
of Problems and Issues The
main problem is the lack of a common strategy for all countries involved in the
Basin management and control regarding multiple uses of water, developing the
means to mobilize resources, and methods by which to occupy and organize space.
Treaties have been signed, but they are not enough, and besides, they are not
always adhered to. It is indispensable that greater cooperation between the States,
and related basin-wide agreements and arrangements emerge. The same applies to
all social actors. Un coordinated actions, based on local and sectorial interests
have a negative impact on the Basin resources and generate accelerated environmental
damage, which both adversely affect the potential of the basin to serve its population
and could ignite conflicts between neighbouring countries in the future.
The magnitude of the basin, the different systems in place to organize the geographical
space, and the competing uses of natural resources - especially water resources
- present problems at different levels, including between the five states. The
main problem is the lack of a common basin management strategy for the different
countries, particularly regarding the compatibilization of energy exploitation
and the coordination of actions aimed at controlling water pollution. Both issues
have caused, on several occasions, international conflicts.
Although some countries have special national organizations to deal with the Plata
Basin, these have proved to be ineffective in terms of specific actions. There
are also multilateral and bilateral treaties and agreements between the countries
in order to manage the major sub-basins, but, in general, the results have been
the same and there are no clear and mutually respected inter-state policies. Even
at the sub-national level, regions do not work efficiently together in the management
of shared resources and spaces. Consequently, a basic problem is the lack of cooperation
between the national States in order to arrive at the coordinated and integrated
management of the Basin.
Territorial ordaining constitutes
both a technique and a policy. It is an interdisciplinary technique that seeks
to analyse relationships between society and the space it occupies. As a policy,
territorial ordaining tends towards territorial planning, gathering techniques,
and the analysis of tools, policies, strategies and plans for the service of society,
aiming at ordaining the available resources in order to meet the desired objectives,
and to attain a more harmonious relationship between society and the environment.
The main antecedents regarding territorial ordaining as a policy can be found
in Europe. France, with its "Amenagement du territoire", is a clear
example. The European Union has produced the European Letter for Territorial Ordaining.
This letter is the result of several documents, including Europa 2000+, and the
European Territorial Strategy and Guidelines towards a European Territorial Policy.
| This
leads to a further problem; the various sectoral policies (lacking prevailing
orientations and strategic reference frameworks) have negative impacts on the
management of the basin's geographical space and on the sustainability and quality
of the water resources. This creates difficulties in optimizing the different
uses of hydric resources, most importantly impeding the obtaining of non-polluting
energy. Finally, the "de facto" occupation of the territory, without
a strategy on territorial uses and ordaining (see box), is causing
accelerated environmental damage which greatly affect the hydric resources.
Characteristics of Conflicts
Several international conflicts have originated from the problems described above,
specifically: incompatibility between major water works; important works which
remain unfinished; and incompatibility between the different uses for hydric resources.
Works are planned and built without a proper strategic framework for financing,
protecting the environment or compensating and rehabilitating affected communities.
International conflicts arise between energy production and navigation. The quality
of the water is also seriously threatened by the uncontrolled expansion of urbanization;
improper land use; localization of polluting activities and unsustainable infrastructure.
Deterioration of natural environments has aggravated water risks, such as prolonged
droughts and devastating floods, and threatens many of the unique natural ecosystems
and features of the basin.
To sum-up, there are potential and actual conflicts arising from:
Incompatibility between water exploitation works, especially those related
to energy.
Lack of efforts to make different projects in the basin compatible.
Building of works and infrastructure projects without a strategic framework to
contain or control them.
Conflicts between energy production and river navigation.
Exploitation of territories, their natural environments and resources, with severe
problems of environmental deterioration, regarding the basin as well as regarding
the quality of hydric resources, and the rise in conflicts created by water risks
(swellings, floods, droughts, etc.).
Among the main processes which cause conflicts at the national and international
level are:
- Uncontrolled urbanization and periurbanization processes.
Anarchic development of human settlements and a pronounced increase in population
and subsequent river pollution.
- Uncoordinated dam construction.
- Compulsive extension of vertical and horizontal
farming and cattle frontiers.
- Accelerated de-forestation.
- Losses in biodiversity.
- Migration and heavy demographic pressure on ecosystems.
- Soil deterioration and erosion.
- Increase in sedimentation in the Basin's watercourses
and decrease in water flow speed within the river-beds.
- Sudden changes in ground water levels.
- Increase in frequency and duration of droughts. This
project aims to obtain an overall vision of the La Plata Basin, in order to focus
later on selected pilot cases. These pilot cases will allow the populations and
governments in the basin to identify and address problems and conflicts more effectively,
as they will recommend specific actions in terms of cooperative management (planning,
cooperation, agreement, coordination, etc.).
This is very important as most conflicts in this water rich basin are due to:
management and institutional problems; lack of trust and, consequently, lack of
agreeements between countries, states or provinces; and lack of communication
and consideration between social actors. In order to overcome these many problems
and conflicts, political will is required, and this is something never easy to
achieve. Project
Foundations The
geographical space of the La Plata Basin constitutes, despite its large dimension,
a unit within a bigger space, that of the MERCOSUR territory. Many studies have
been done on the Plata Basin, especially regarding problems related to energy
use and there is extensive documentation and analysis on the subject. However,
none of these studies offers an overall view of the water problem as regards the
occupation, organization and dynamics of the territorial system and the consequent
internationalization of conflicts.
Consequently, it is imperative to have an integrated approach to the territory
in the Basin and to apply this vision and the methodology ensued to a particular
sub-region of the Basin (the selected region is the Upper Paraná), where
three nations take part, which has been exposed to multiple uses and where water
regulates the territorial system. Finally, five case studies will complete the
vision of the interaction of different variables at the various selected levels.
Therefore, the proposal considers the following approach:
Water should
not be considered merely as a resource and even less as an economic asset. The
current trend is to consider it as a physical medium (Moratilla, 2001) and a social
asset.
Water, considered
as a physical medium, also becomes a strategic asset; there is an inseparable
association between social development and the water culture.
Efficient water
management should be framed within a territorial development and ordaining strategy
of the basin as a basis for sustainability.
Consequently,
it is necessary to consider different view-points which may associate and identify
water uses with: urbanization processes; localization of productive activities;
land uses and appropriations; infrastructure design and functioning; and the integrated
management of natural ecosystems and their resources.
Both the local
and transnational dimension must be treated, both for the analysis of situations
and the development of strategies.
The territorial
strategy offers the possibility to promote the integration of sectoral management
measures for water resources with the objectives of protecting and preserving
ecosystems and human welfare. Likewise, it is the reference framework used to
coordinate between other sectoral policies (production, energy, transportation,
urbanization, etc.) and the different levels of administration (national, regional,
local); and, above all, to construct the framework for transnational integration.
An integrated management
of the resource should be inscribed within a general framework of territorial
ordaining and development and should also be established as a means to avoid present
and unforeseen international conflicts. This
approach, applied to the Plata Basin, indicates that efforts should be aimed towards
two major points:
1. Water as a development factor, both as an energy
source and as an asset for human development
2. Water as a risk trigger. The
concept of integrating actions should consider three levels.
1. Integrated and joint management of transnational
basins.
2. Integrated and joint management for the different
origins and uses of water.
3. Integrated and joint management with the participation
of civil society and the different jurisdictions involved at national and sub-national
levels. The
territorial capacity to sustain population and activities needs to be evaluated.
Incorporating water management with a territorial ordaining strategy for the Plata
Basin is a potentially highly beneficial initiative. It presents a new challenge
and an innovation in management which, because of its many dimensions, requires
the strengthening of cooperation between the basin's constituent states, regions
and civil society. Project
Description and Justification Principal
Objective
The project's main objective is to achieve a systemic approach to problems and
conflicts by identifying the causes, establishing the situation and practical
recommendations tending to the solution of present and potential problems, promoting
forms of cooperation, agreement, collaboration and coordination, within the framework
of a territorial ordaining strategy, in accordance with international experience
in other regions. Considering their wide regional and economic impact and conflict
potential, priority will be given to the Binational hydropower exploitations projected
for the region: Corpus (Upper Paraná), raising of the Yacyretá dam
level (Upper Paraná); Garabí (Upper Uruguay) and Las Pavas; Arrazayal
and Cambarí (Bermejo's Upper Basin) and Cierres North and South of the
Middle Paraná.
Specific Objectives
To identify hindrances
and benefits (weaknesses and potentialities) for the improved management of the
basin.
To identify possible
ways of improving management through pilot projects.
To guide hydro-project
developments in such a way that they will allow comprehension, perception and
public and political awareness about integrated resources management. This should
be done considering territorial ordaining aspects, anticipating and preventing
inter-jurisdictional conflicts, especially international ones.
To propose innovative
ways of participation for society at all levels, in terms of analysis as well
as in terms of management.
To anticipate
and prevent potential conflicts at the international level, as a result of unilateral
actions or as a consequence of the dynamics of the Society Economy
Environment Territory system, with special emphasis on the
management of shared hydro resources.
To produce an
objective study of the problems involved in the construction of projected dams
in the Basin in order to foster coordination between authorities from the different
countries, and preempt problems.
This objective will be applied at three levels: the Plata Basin, the Upper Paraná
Axis and five cases with specific conflicts. Expected
Results The
realization of this project, its approach and methodology, will provide a global
framework permitting the evaluation of projects in general, and hydropower projects
in particular, related to the Basin's socioeconomic sustainable development. This
study, added to the works which Green Cross has been doing in relation to certain
specific cases linked to water resource management (especially in Yacyretá),
will allow an interaction with the political authorities of the nations within
the Basin in the search of management strategies based upon agreeement and cooperation,
which will help to diminish the present problems and conflicts. Activities
and Actions
Activities and actions to be developed aim to attain a realistic view of the ruling
principles which should be taken into account in the Basin development, and, from
that, arrive at specific recommendations in the five pilot projects to be studied.
Project
Implementation
The project will be implemented in three stages, partially superimposed in terms
of time. The first stage will aim at obtaining a general view of the Plata Basin,
starting from problems and conflicts. The second stage will approach the Upper
Paraná Sub-region in the same manner, and in the third stage Pilot Projects
will be developed. These were selected due to the existence of latent conflicts
which require technical support in order to be resolved. Project
Justification
There is a lack,
within MERCOSUR in general and particularly within the Plata Basin, of a territorial
ordaining and development strategy to guide processes in the search for a territorial
re-balancing, greater economic and social cohesion and a balance between territorial
competitiveness and environmental sustainability. Integrated water management
must be an essential part of this strategy.
The approach
to river basin management, within a territorial ordaining strategy, is relevant
to the project since it establishes an overall approach to interrelations between
water, its possibilities as a vital resource and human activities in terms of
territorial occupation and uses.
In order to prevent
new conflicts, to increase benefits and to reinforce cooperation among the Basin's
member States, more effective participation of regions, provinces and municipalities,
as well as more active citizens' participation and a permanent collective work
between public Administration and the private sector are needed.
The implementation
of this project, with this approach and methodology, will permit a global reference
framework for the future, from which it will be possible to analyze and evaluate
different public and private projects and examine their impacts at different levels.
The project is
also justified as it promotes the idea and the awareness of the need and opportunity
for joint management of the Basin's water resources and territorial ordaining
in order to aspire to a sustainable development.
This implies
a total innovation in public policies, jointly agreed by the State members of
the Plata Basin. Reasons
for selecting the Upper Paraná and Pilot Projects Sub-regions:
The Upper Paraná
sub-region, as well as the region which includes the pilot projects, have
been selected to represent specific cases which show more clearly the problems
and conflicts identified.
Upper Paraná
constitutes a trans-border fringe where the Paraná River articulates regional
life. It is also subject to a strong pressure caused by several undertakings,
among them the Yacyreta dam (one of the largest in the world), the effects of
which are at present being amplified with new constructions over the outlet and
the raising of the dam level. At the same time, another dam, Corpus, including
a hydroelectric plant, will be built upstream from Posadas. To all this, there
must be added the works corresponding to the Paraguay-Paraná hydroway,
the foreseen ports (Santa Ana Urugua-i) and existing undertakings such
as Itaipú (Brazil) and Uruguai (Argentina).
Works linking
new ports, highways and railways, as well as a re-ordaining for urban areas affected
by the dam reservoir waters, should be underlined. All these will have a strong
impact on the environment, with special emphasis on some protected areas such
as the Iberá marshes and Iguazú National Park. All
of the above, briefly summarized, demonstrate the importance of the selected sub-region
and its relationship with the territorial ordaining project. Brief
Description of Pilot Projects
a) It is important to
evaluate the relevance of water as an energy generator, applied to Yacyretá,
Corpus and Garabí exploitations and with regard to new possibilities
such as the building of combined cycle utilities. The production of clean, non-polluting
and renewable energy is confronted here with energy obtained from exhausted, polluting
resources.
b) Certain Bolivian
mines have caused pollution in the Pilcomayo River, due to the use of arsenic
and heavy metals. This has caused great alarm downstream, where the river constitutes
the international border between Argentina and Paraguay. Recently, certain corrections
in the river's course have caused drought in some branches, with high fauna death
toll, especially affecting the Yacaré Overo.
c) The horizontal and
vertical extension of farming and cattle ranching in the north of Argentina's
Pampean region has caused serious pollution problems in the river waters and in
the Nappes, due to an excessive use of chemical fertilizers and pesticides.
d) In the Upper Paraná, the sub-region that will be primarily studied,
serious problems have been detected, causing severe changes in water's physical
and chemical properties. This has led to a loss in water quality, at the same
time changing the fauna balance and affecting fish stocks. Main factors responsible
seem to be human uses of the soil and the pressure on ecosystems.
e) The Bermejo River is shared by Argentina
and Bolivia. It has a high energy potential in the upper basin, shared by both
countries, and a potential for multiple uses involving irrigated land and the
supply of drinking water to the middle and lower basin. Several polemical channeling
projects already exist here. At the same time, the Bermejo drags sediments which
contribute 70% to the filling of navigable routes in the Middle and Lower Paraná
and affect the access channel to the Río de la Plata. There is a bi-national
committee (Argentine-Bolivian) for regulation; in reality it is primarily dedicated
to the hydropower exploitation of the upper basin where there are three undertakings
(ARRAZAYAL; LAS PAVAS; and CAMBARÍ). Green
Cross's Role as an Actor in the Basin
Throughout the last years, Green Cross has taken part in several projects related
to water management in the region. Of these projects, the most important ones
are the intervention during the floods in Corrientes under the influence of the
Niño stream, and a project developed since 1999 related to social and environmental
problems generated in Yacyreta's bi-national (Argentina - Paraguay) dam zone of
influence. Besides, for more than two years, Green Cross has been present in Uruguay
and offices are being set up in Brazil and Bolivia and in Encarnación,
Paraguay, as part of the Yacyretá project.
These circumstances, together with Green Cross International's acknowledged experience
in the search of solutions for conflicts related to water use, show this is the
idea time for this wider project to be realized. The above mentioned prior activities
and the realization of the Water for Peace study now proposed will allow Green
Cross to make a valuable contribution towards the seeking of political consensus
between the Plata Basin states.

involving participation of all agents involved, whether public (local, regional,
national and community administrations) or private (social or economical agents,
corporations, associations, universities, etc.).
To make possible a joint and integrated management
of the basin at transnational level, as a part of a wider territorial strategy
for MERCUSUR Project
Activities Three
levels of activity can be distinguished:
a) OVERALL ANALYSIS
OF THE BASIN ENVIRONMENT as a reference framework, which will be developed starting
from specific subjects and prevailing issues.
b) REGIONAL ANALYSIS,
which will include a transfrontier fringe dominated by the UPPER PARANA, between
the cities of RESISTENCIA, CORRIENTES POSADAS and PUERTO IGUAZU. The methodology
followed for the global analysis (REGIONAL PILOT PROJECT) will be applied in greater
detail in this sub-region.
c) Specific pilot projects, which will attend to the
prevention and/or resolution of conflicts: this will require in-depth analysis
and a renewal of management mechanisms. Main
Activities Activities
will be organized around the following points:
1. Tendencies in water management within the basin.
2. Tendencies of change in
city systems and urbanization processes: Spatial and social re-functionalizing.
3. Tendencies in productive
systems: relationships between the productive system and the use and/or deterioration
of the basin's hydro resources.
4. Tendencies in the
transport and energy networks.
5. The problem of natural
environments and their resources. Analysis of losses in natural environments due
to expansion of productive processes, urbanization and peri-urbanisation, and
lack of inter-state cooperation.
6. Water as a territorial
organizer and development factor Water as risk trigger and phenomena that can
cause social catastrophes.
7. Integrated analysis
of the functioning of the territorial system, identifying problems and their degree
of permanence and severity.
8. Identification of
plans and projects within a strategic framework that will allow the project to
recommend Ruling Guides for sustainable territorial development including integrated
management of water resources. The
activities to be developed will be particularly applied to the Upper Parana trans-frontier
space. Another
group of activities will include the analysis of the five pilot projects identified
from the detection of "key problems" which affect sustainability of
the regional water resources and which determine the territorial sustainable development.
The project will
be successful if it succeeds in orientating investigations towards practical questions,
based on solid technical knowledge, which might be useful in finding solutions
to the questions, problems and conflicts which have been subject to errors for
years. It will
succeed if the approach, question analysis and proposed actions enable the updating
of methods of public-private management in handling natural resources especially
water resources-, as well as uses, occupation and appropriation of territory,
permitting the achievement of environmental and social sustainability. Potential
