International Conference on Lake Victoria (LV2000: A New Beginning) Held on 16th - 19th May, 2000 CONFERENCE RECOMMENDATIONS
1.
PREAMBLE
The
LVFO is an inter-governmental Organization established through a Convention
signed by the three Contracting Parties of Kenya, Uganda and Tanzania on 30th June, 1994 in Kisumu, Kenya. The main objectives of the LVFO are; to
foster co-operation amongst the Contracting Parties in matters regarding Lake
Victoria, harmonize national measures for the sustainable utilization of the
living resources of the Lake and develop and adopt conservation and management
measures to assure the Lakes ecosystem health and the sustainability of the
living resources. In
order to fulfil its objectives the LVFO Secretariat needed information on Lake
Victoria and therefore decided to hold an International Conference. The
objectives of the Conference were, to gather as much information as possible on
the research that has been done on Lake Victoria resources and environment,
identify gaps in knowledge and decide the way forward for the management of the
Lakes living resources. Based on these simple objectives five Conference themes were
identified as follows: 1.1
Multiple resource uses of the Lake Victoria basin and natural phenomena Impact
of human population, land use, livestock and industrialization on the aquatic
environment. Status of limnology and water balance. Pollution, siltation and
eutrophication of the lake and their effect on the water quality and fisheries.
Use of Geographic Information System (GIS) and Satellite Imagery to monitor the
lake environment and its catchment. Climate change and the aquatic environment. 1.2
Roles of science, economics and politics in fisheries management Lake
Victoria-River Nile agreements. The stakeholders in the fishing industry. The
role of indigenous knowledge in fisheries management. Fishing communities and
modernization. Good governance in the lake Victoria basin and political will to
manage its resources. Harmonization and enforcement of fisheries
laws/regulations. Fish processing and quality assurance. 1.3
Development of the fisheries sector Fisheries
potential of Lake Victoria. Riverine fisheries. Policy formulation. Access to
the fishery. Regulation of fishing gears and methods. Contribution of
aquaculture to the Lake Victoria basin fisheries production. Infrastructure
development. Institutional and human resource capacity building. Credit
facilities to fisher folk. Sustainability of the fisheries sector. 1.4 Roles
of conservation in biodiversity and fisheries sustainability
Status of biodiversity in the Lake Victoria basin. The
impact of invasive species. Conservation of genetic resources for aquaculture
and other uses. Value of wetlands.
1.5
Integrated Lake basin management Land-lake
interaction processes. Coastal zone management. Deforestation, afforestation,
rational land use practices. Role of communities in co-management. Concept of
ownership of resources. Relationship between researchers, extension and fisher
folk. The science plan for Lake Victoria beyond 2000. Each
theme had a keynote paper that was prepared by a group
of stakeholders and was
presented before the other papers in that theme during the Conference. The
keynote paper authors together with other scientists discussed each theme in a
pre-conference workshop and made a
set of recommendations which were
further refined and focussed during the Conference presentations, deliberations
and discussions. After the Workshop
there were a set of recommendations specific for each theme. Later on general
recommendations were drawn up for Lake Victoria, incorporating recommendations
from the Workshop on People, Fisheries,
Biodiversity and the future of Lake Victoria held in August, 17-20, 1992 in
Jinja, Uganda. 2.
EXECUTIVE SUMMARY 2.1
Issues of concern for the Health of Lake Ecosystem Concomitant
with the shifts in fish stock structure and dynamics are changes in resource use
and ecosystem health. The major
issues relating to these changes can be categorized into the following: 2.1.1 Contamination and
toxic effects from industrial and urban development around the catchment (heavy
metals especially mercury, persistent organochlorines, current use of
pesticides); 2.1.2 Eutrophication
(excess nutrient loading resulting in high algal populations and blooms which
cause taste and odour problems, high water treatment costs, algal toxins,
deoxygenation, associated pathogens and alteration in consumer food webs); 2.1.3 Deoxygenation of
the lake bottom waters caused by excessive input of oxygen using materials; 2.1.4 Deforestation and
resultant siltation (excessive turbidity and sedimentation); 2.1.5 Alteration of physical
substratum causing loss of fish habitat; 2.1.6 Biological pollution
(species introductions, modifying food webs and causing uncertainty about future
resource base); 2.1.7 Loss of biodiversity
(species and wetlands) in the lake region; 2.1.8 Over-exploitation of
the fisheries (modifying food webs and causing uncertainty). 2.2
Institutional Framework 2.2.1 States should ensure that an appropriate policy, legal and
institutional framework is adopted to achieve the sustainable and integrated use
of Lake Victoria basin (LVB) resources, taking into account the needs of the
communities, the fragility of the ecosystem and the finite nature of its natural
resources. 2.2.2
States should ensure that representatives of all sectors (and
stakeholders) are consulted in
the decision-making processes and involved in other activities related to
planning, development and management of the Lake Victoria basin. 2.2.3
States should develop, as appropriate, institutional and legal frameworks
in order to determine possible uses of resources and to govern access to them
taking into account the rights (custodianship and proprietorship) of the Lake
Victoria basin fishing communities and their customary practices to the extent
compatible with sustainable development. 2.2.4
States should promote the establishment of procedures and mechanisms at
the appropriate administrative level to settle conflicts, which arise within the
fisheries sector and between them and other users within the Lake Victoria
basin. 2.2.5
States should limit new fish processing plants and also pirate processing
plants created prior to or in violation of licensing. 2.2.6
The commercial aquaculture potential of the region is high, but is very
far from being achieved. It is recommended, however, that States should adopt a
cautious approach to large scale aquaculture development because such
initiatives can impact biodiversity through acceleration of sedimentation rates,
the accrual of uneaten food increases eutrophication and antibiotics and
antifouling compounds can lead to local toxic pollution. There are also risks of
contamination and introductions of species and genetic varieties that are
foreign to the lake. If commercial aquaculture is to be developed it should be
based on local species only, e.g. Oreochromis
niloticus and Clarias gariepinus. Mirror
carp and other exotic species must be avoided. 2.2.7
Riparian States should offer members of communities opportunities for
education and training sufficient to provide access to alternative means of
employment, and/or material assistance in relocation. 2.2.8
States should preserve typical refugia areas through protected area
status or as part of integrative co-management programs. A coherent plan for
conservation and rehabilitation of the lake basin fish faunas should also be
developed without delay on the following basis:
Provisions
for the setting up of reserves typifying the various habitats of the lake, its
tributary rivers, associated wetlands and satellite lakes, after an appropriate
inventory has been conducted; Human aspects of such reserves should be agreed through consultation with local groups; Formulation
of strategies to reinforce conservation, financial and social value on the
resources to be protected; Education
programmes addressed to all levels of society aimed at clarifying the benefits
from conservation and defining the processes needed to achieve it. 2.3
Policy Measures 2.3.1
States should promote the creation of public awareness of the need for
protection and management of resources and participation in the management
process by those affected. 2.3.2
States should promote the assessment of the respective value of the wetlands
taking into account social, economic and cultural factors. 2.3.3
States should address the risks and uncertainties and adopt as a precautionary
approach in setting policies for the management of the Lake Victoria
basin. 2.3.4
States should establish or promote the establishment of systems to monitor the
Lake Victoria basin environment, as part of the management process, using
social, economic, physical, chemical and biological criteria. 2.3.5
States should promote multidisciplinary research in support of management
of Lake Victoria basin with respect to social, economic, legal, political,
environmental, administrative, technical and biological criteria. 2.4
Regional Co-operation 2.4.1 States of the Lake
Victoria basin should co-operate to facilitate sustainable use of its resources
and conservation of bio-diversity (and its environment). 2.4.2
In the case of activities that may have an adverse effect upon the Lake
Victoria basin environment, States should:
Provide timely information and, if possible,
prior notification to potentially affected States;
Consult with those States as early as
possible. 2.4.3
States should strengthen existing regional mechanisms (e.g. of East African
Community (EAC), LVFO) in order to facilitate co-operation and co-ordination
among agencies involved in the planning, development and management of the Lake
Victoria basin. 2.4.4
The LVFO should be the lead organization, responsible for facilitating
collaboration and co-operation with respect to the development and harmonization
of activities affecting the Lake Victoria basin. 2.4.5
The LVFO will collaborate with stakeholders, relevant inter-governmental
and non-governmental organizations and financial institutions to promote the
effective integration of management for Lake Victoria basin. 3.
SPECIFIC THEME RECOMMENDATIONS 3.1
Multiple Resource Use and Ecosystem Health of the Lake Victoria Basin A
program of focussed research is required to establish a baseline of conditions
for the aquatic resources against which the efficacy of management action or
inaction can be evaluated. This monitoring program could provide necessary data
to quantify current fluxes of nutrients, contaminants and sediments into Lake
Victoria. The main activities required are: Watershed
research into effects of land use practice on river water quality and modeling
of the important processes to evaluate inputs into the lake and to evaluate
expected outcomes of management interventions; Wet
and dry fall monitoring networks for nutrients and contaminants must be
established so that the largest single water flux into Lake Victoria rainfall
can be evaluated for its loading characteristics.
A network is needed in order to pinpoint regional sources for atmospheric
contamination; Socio-economic
constraints on effective erosion control must be determined and addressed
through education and development programmes; An
effective integrated long term monitoring program must be established for the
airshed, watershed and for the lakes resources; lack of such programmes have
led to the massive uncertainty faced by the stakeholders of the basin today; A
research programme should be established to evaluate the mode and effects of
algal toxin production in Lake Victoria in which the phytoplankton are now
dominated by species of cyanobacteria known to be toxic to vertebrates; this
program should include a risk assessment of the threat. 3.1.1 Recommendations on management and policy issues There
is need to encourage: o
A Population stabilization and control programme; o
Effective land use and urban planning (especially in
riparian zone); o
Widespread soil erosion control programmes; o
Improve fertility of land through increased use of
fertilizers (but this must be in combination with effective erosion control) as
well as water and soil management at farm scale; o
Conservation of soil and water at the watershed scale
especially wetland conservation; o
Economic development to reduce dependence on small
scale farming in marginal lands. 3.2
The Role of Sceince, Politics and Economics in Fisheries Management
3.2.1 Management of the Lake Victoria fishery should be elaborated within the framework of the Code of Conduct for Responsible Fisheries and its Five Principal Ps of: Process; Precaution; Partnership; Proprietorship; Policing.
3.2.2 Management should be directed towards human ecosystem of multiple scales encompassing, for example: The
Lake Victoria basin; Watersheds
of tributary rivers; Delineated
wetlands; Satellite
lakes; Protected
areas; Pilot
landings; Lake
zones. 3.2.3 Encourage
co-management by interest groups whose participation is facilitated and fostered
inter alia, by the following:
Education and active learning;
Participatory research;
Development training in practical skills and
techniques by and for each interest group. 3.2.4 The
Lake Victoria basin members of
communities should be offered opportunities for education and training
sufficient to provide access to alternative means of employment and/or material
assistance in relocation. 3.2.5 States
should identify areas where traditional environmental knowledge offers a basis
for community participation in management. 3.2.6 Governments should identify
the contributions of population growth and economic development to land use
changes impacting the Lake Victoria ecosystem, and further to address these
basic causes through population programmes (education and economic security for
disadvantaged groups, family planning assistance) and through environmental
regulation. 3.2.7 Partner
States should implement and maintain systems of information collection
concerning the economic, social, institutional, and cultural elements of the
Lake Victoria fisheries, including changes in these elements over time.
Socio-economic research capacity must be strengthened for the collection,
analysis, and dissemination of these data. 3.2.8 Stakeholders need to
understand the interactions between biological and physical factors with social
and economic factors. All ecological and field biology research projects should
include a socio-economic component. 3.2.9 States
should give consideration of both biological-physical factors and
economic-social factors. In most cases, the element that is immediately being
managed is the human behavior. We recommend, therefore, that fisheries managers
be trained in both biological-physical and economic-social dimensions of
science. 3.2.10 Governments should address
gender issues in all resource management projects. 3.2.11 Riparian countries
should make comprehensive studies of the fisheries extension function in the
three lacustrine countries with a view to identify barriers to the effective
communication of relevant research to various user groups. 3.2.12 Countries must support
additional research to assess the benefits and disadvantages of systems of
tenure (e.g. individual or community quotas), custodianship, and proprietorship,
with special attention to the public trust in natural resources. 3.2.13 States should support
increased research and monitoring into the potential conflicts in the use of
fisheries products (e.g. fish for food, fishmeal, foreign exchange generation).
This research and monitoring should contribute directly to the formulation of
intervening policy measures. 3.2.14 Government policy makers as
well as resource users need to take this information into account in their
decision-making. 3.3
Development of the Fisheries Sector in Lake Victoria 3.3.1
Current state of the fishery
The
Conference noted that Nile perch, Nile tilapia, and Rastrineobola argentea (mukene,
omena, dagaa) stocks are showing
diverse and widespread signs of growth over-fishing, particularly on the Eastern
side of the lake. Although specific information vary from place to place within
the lake, the institution of several key, general conservation measures is
strongly urged. In addition, with processing plants now apparently preferring
relatively smaller Nile perch for their fillets, fish are being caught hard at
sizes that are dangerously close to the minimum size at sexual maturity, which
is itself much smaller than the ideal size for maximized productivity of the
Nile perch population. 3.3.2
Growth of the regional database 3.3.2.1 States and the Development
Partners should support the establishment of a regional database. 3.3.2.2 Member countries of Lake Victoria should support stock
assessment of indigenous species, food web analysis and life history studies. 3.3.2.3
Governments should promote and encourage an overall investment strategy
in fisheries research and monitoring if the fishery is to be sustainable. 3.3.3
Limit to processing capacity 3.3.3.1 States
should control and limit the fish processing capacity. 3.3.4
Private Sector involvement in conservation 3.3.4.1
Riparian Governments should foster collaboration between the fisheries
community and the exporter companies in order to enhance surveillance
and compliance. 3.3.5
Sustainability 3.3.5.1 States
should support and strengthen sustainable exploitation of the fishery resources,
avoid over-capitalization of the industry and depletion of stocks. 3.3.6
Sharing the big picture 3.3.6.1 The LVFO,
in collaboration with Governments should institute regular
regional harmonization meetings for both the scientists and the policy
makers to enhance the socio-economic benefits of fishers. 3.3.7
Aquaculture 3.3.7.1 States should promote and encourage commercial aquaculture of Oreochromis niloticus, Clarias gariepinus by community or co-operative fish farms, mini-dams, and kitchen ponds (as appropriate and desirable). 3.3.7.2
Governments should discourage the culture of mirror carp and other exotic
species (aside from O. niloticus) in
open lake cage culture and satellite lakes. 3.3.8
Conservation of indigenous food fishes 3.3.8.1 Riparian
countries should conserve indigenous riverine and satellite lake food fishes and
support programmes aimed at learning how to better culture and conserve these
species. These programmes must be
greatly accelerated before it is
too late and such species have been lost. 3.3.9
Management Zoning 3.3.9.1 A zoning
system for the management of human activities in the lake and lake basin as a
whole be instituted. 3.3.10
Fish Quality 3.3.10.1 Fish assurance
quality control and training be built around a programme exploiting eco-labeling
and a fair trade association. 3.4
Role of Conservation in Biodiversity and Fisheries Sustainability
3.4.1
Conservation of biodiversity in the Lake Victoria basin
One of the major moral dilemmas of today concerns its use of natural resources. On the one hand there is the need to satisfy the nutritional requirements of a growing human population. On the other there is the need to conserve existing genetic, specific, and ecosystem biodiversity for future generations. These two imperatives are frequently in conflict because the maximization of human societal needs for food, goods, and infrastructure involves the disruption of existing habitats and living aquatic communities. Efforts to resolve this conflict have been encouraged in a number of international forums including the Convention on Biological Diversity (CBD). 3.4.2
Planning It
was stressed by the Conference that any project to protect or restore the
biodiversity of the lake should form part of the integral lake plan.
Such plans are necessary so that national priorities can be developed at
high political level on the basis of which funds can be located and legislation
drafted. It should also be included
in the national biodiversity planning which is part of the national obligation
under the CBD. Additional support can also be sought through the major wetland
conventions such as RAMSAR. The
influence of upstream activities is particularly important in the case of rivers
and riverine wetlands and also for the main lake, as it is a major source for
eutrophication and the related decrease in water transparency and dissolved
oxygen concentration. Conservation
Reserves in such environments are only effective if they are formally included
in general plans for the basin as a whole.
It is suggested that the development of an overall policy for
biodiversity conservation is of high priority.
The policy should be incorporated into more generalized planning for the
conservation and management of the natural resources of the lake and its basin. 3.4.3
Protection of environmental
quality The
conference acknowledged the fact that any attempt to conserve biodiversity in
the lake can only be pursued if the environmental quality is at a satisfactory
standard. Such efforts should
include the maintenance of water quality in the lake, its tributaries and
associated wetlands and measures to reverse the trend of increasing
eutrophication. Adequate
and timely flows are needed for the completion of the life cycle of many species
of migratory fishes in the tributary rivers. Adequate water quantity is also needed for the protection of
wetlands, and efforts to drain such areas for agricultural and urban use should
be resisted. Forested buffer strips
will also be important in the maintenance and improvement of water quality
(e.g., increased water clarity). The
impact of other users of the aquatic resources on fish assemblages reinforces
the principle that any conservation policies must be integrated into the wider
planning of all activities at basin level. 3.4.4
Control of
the fishery The
Conference noted that there is no doubt that, apart from the Nile perch episode,
fishing has exerted a major effect on the magnitude and composition of the fish
stocks. Furthermore, because of the
well-documented losses in biodiversity that occur in multi-species fisheries
with increasing fishing pressure the best conservation strategy should be linked
to rational control of fishing effort in order to prevent the serial collapse of
stocks that characterized the past history of the fishery. 3.4.5
Protected area management of
maintenance of faunal refugia The Conference recognized two types of biodiversity banks:
refugia within the lake and refugia outside the lake.
Efforts should be directed toward the maintenance of these biodiversity
banks. Many of these refugia are also critical habitats for economically
important fish (e.g., wetland ecotones are important nursery areas for the Nile
tilapia; rocky shores are important refugia for Labeo victorianus, Bagrus
docmak, and Oreochromis variabilis)
and thus could serve a dual role as a conservation area and harvest reserve.
3.4.6
Reserves and protected areas in
the lake States
should appreciate that typical areas of the lake should be reserved for
conservation. These should include a selection among rocky shores, sandy shores
and mud bottomed bays. Each of
these harbours different faunas of often habitat-restricted species.
This should be done after an appropriate inventory of the basin has been
completed. 3.4.7
Aquaculture It
was noted that there is a growing interest and support for enhancing the native
Lake Victoria fishery using aquaculture. The
Conference recommended a very cautious approach to large aquaculture development
because such initiatives can impact biodiversity in a number of ways.
Cage and pen culture can accelerate sedimentation rates, the accrual of
uneaten food increases eutrophication and antibiotics and antifouling compounds
can lead to local toxic pollution. 3.4.8
Conservation of genetic
biodiversity The Conference was informed that a 10-year study on the conservation of
genetic biodiversity in the Lake Victoria region has revealed the existence of
enormous biodiversity, and highlights the need for continued studies in the
region. The genetic patrimony of
the lake may be further threatened in the future. It was recommended that
States should take great care in following the existing protocols governing
movements, introduction, and stocking of fish into the lake or its satellite
water bodies. 3.4.9
Wetlands management and
conservation The
riparian States should give priority to the maintenance of wetlands in the Lake
Victoria basin. This is critical to both ecosystem function and the conservation
of indigenous species both in wetlands and in the lake.
Numerous anthropogenic activities including primarily reclamation for
agricultural production, but also irrigation systems, canalization,
mining/extraction and industrial and municipal pollution currently threaten
wetlands. Current strategies for the sustainable management of wetlands include
co-management systems for shoreline wetland resources (multi-stakeholder
strategies), protection mediated by such activities as economic valuation (e.g.,
Yala Swamp), Ramsar status (e.g., Lake George, Lake Nabugabo), and other efforts
such as the River Nyando and Sondu-Miriu Conservation and Rehabilitation
Project. 3.4.10
Biodiversity survey, standardized
monitoring and evaluation The
East African States should support remnant populations of species that have
persisted with Nile perch. These
are extremely important because they are the seeds for resurgence should
predator pressure be reduced. In
some Satelite lakes of the Victoria basin and some sections of Lake Victoria
itself, over fishing has reduced the numbers of large Nile perch and sparked a
resurgence of indigenous species. There
is no doubt that this is a biologically filtered fauna, representing species
that have persisted with Nile perch and species with the flexibility to respond
quickly to reduced predator pressure. However,
the composition of the resurging fauna, the speed of resurgence, and the nature
of the recovered food web are largely unknown. This calls for standardized
taxonomically and ecologically detailed biodiversity survey and monitoring that
is compatible with ongoing inshore and offshore stock assessment, but must
include a broad suite of representative habitat types.
It should encompass within- and between-site replication so that changes
may be detected with adequate sensitivity and rigour. 3.4.11 Reintroduction The
riparian Governments should study the recent proposals for reintroduction of
cichlid species into satellite water bodies.
The uncertainty about population trends and lack of protection drive this
need, at least currently, in the main lake. However, much caution must be executed in considering this
intervention because of potentially negative genetic effects. 3.4.12
Recommendations The riparian Governments should take note of the
resurgence of some indigenous species increasingly evident in areas of Lake
Victoria and Lake Nabugabo, which has given new hope for the maintenance of
biodiversity in the system and a renewed interest in careful management options
that promote sustainability of the fishery and biodiversity conservation. A
coherent plan for conservation and rehabilitation of the lake basin fish faunas
should be developed without delay. The
plan should encompass the following:- o
Provisions for the setting up of Reserves typifying
the various habitats of the lake, its tributary rivers, associated wetlands and
satellite lakes, after an appropriate inventory has been conducted;
o The human aspects of such Reserves through consultation with local groups; o
General policies for the management of the fishery
and for the range of other human activities in the lake basin. This will involve
negotiation with other interested stakeholders;
o Formulation of strategies to reinforce conservation efforts should be made to place financial and social value on the resources to be protected and o
Education programmes addressed to all levels of
society aimed at clarifying the benefits from conservation and defining the
processes needed to achieve it. 3.5
Integrated Lake Basin Management 3.5.1
Approach
In
building the discussion and recommendations the Conference focussed on the
following approaches: Understanding
that the resources of the Lake Victoria basin
are trans-boundary in character that is influenced by activities at local,
national, regional and wider international levels;
Emphasis
on a trans-sectoral approach where fisheries is only one element to be addressed
in the planning, development and management of the Lake Victoria basin Realization
that any plans and derived strategies must involve all stakeholders, this being
a cornerstone for Human Resource Development (HRD) in the Lake Victoria basin; Awareness
that Theme 5 must integrate with Themes 1-4 and be cognizant of their findings; Recognition
that the findings of all themes should lead to integration and sustainability,
and
Adopting
a matrix that could be used to evaluate issues, options, strategies, and
operational plans based on: social; economic; legal; political; environmental;
administrative; technical and biological factors and the FAO Integration of
Fisheries into Coastal Area Management. 3.5.2
Impacts on fisheries resulting from activities in other sectors The
Conference identified the following impacts on fisheries from other sectors: Degradation
of the ecosystem;
Social
and economic impacts;
The
loss of wetlands of the Lake Victoria basin compromising their role as safe
guards of bio-diversity, and agents of general resource conservation;
Effects
of urbanization and industrialization of the catchment on the traditional users;
The
view of the Lake Victoria basin resources as a welfare device;
Effects
of siltation and erosion processes;
Spatial
conflicts between user groups and problem
of weakly defined property rights;
Temporal
changes affecting the interplay between sectors or processes
agriculture/urbanization/industrialization and the shifting dominance of one
sector over another; Suppression
of one sectors activities by policies of others;
Effects
of tourism;
Impact
of forces transmitted to the Lake Victoria basin by the global market;
Failure
of economic policy instruments to work and
non-compliance;
Role
of inter-ministerial commissions as organizations to broker management of the
Lake Victoria basin;
Question
of how policy instruments may be harmonized and who holds jurisdiction at
various levels; weakness of Monitoring, Control and Surveillance and
Rights
of users to an acceptable level of environmental quality. 3.5.3
Regulatory and economic policy instruments It
was noted that States should address the following:
Role
of stakeholders;
The
problems of non-compliance with the regulations;
Invalidity
of regulatory techniques borne out of inadequate representation/incorporation of
user needs/aspirations; Empowerment
of the community; Inadequacy
of the regulations in relation to different political levels (local, national,
regional and global influence) and
Use
of scientific and non-scientific data bases to help integrate management for he
Lake Victoria basin. 3.5.4
The rights of traditional and customary fishers and fish farmers to enjoy
an acceptable environmental quality Member countries should resolve the following problems:
Conflicts
between the more destructive activities of users in the Lake Victoria basin and
the less damaging;
Impacts
of mining, deforestation, urbanization and changes in the focus and intensity of
agriculture and
Impact
of tourism. 3.5.5
Valuation of Lake Victoria basin resources Riparian
States should give serious consideration to: Establishing
common standards to compare and contrast user activities using different
measures e.g. comparative cost/benefit and/or cost effectiveness analyses;
Under-valuation
of the resource base; Distortions
to value caused by political interventions, cultural idiosyncrasies;
Wider-ranging
assessment of all contributions to value;
Establish
a matrix of valuation tools or devices;
duality
of some sectoral activities e.g. positive impact of urbanization on
demand/markets for fish but human waste discharges may have negative impact; Marginalisation
of fish production, economic value not fully realized; Limitations
of social/economic databases;
Paucity
of regional databases addressing social and economic data collection and Subservience
of socio-economic data collection with respect to scientific domain. 3.5.6
Parameters relating to the integration of fisheries into planning and
management of the Lake Victoria
basin Member
countries should focus attention on:
Social
and economic parameters; Population
density, employment, alternatives to fisheries, income levels;
Physical
and biological parameters;
Holistic
rather then sectorally (boxed) approach;
Seek
to minimize adverse impacts;
Who
will take responsibility for integration; Designated
authority and |
