Abstract(s)
A influência das bacias hidrográficas e suas discargas associadas na zona costeira são
inegáveis. Como resultado, a presença humana e suas atividades nestas áreas de
captação, juntamente com fatores naturais, têm sido e continuam a ser responsáveis
pelas alterações observadas, no estado de deterioração do ambiente costeiro em todo o
mundo, com impactos associados aos benefícios ecológicos e sócio-económicos
acumulados. Na tentativa de avaliar estas descargas e compreender as relações que
ocorrem entre a bacia de captação e a costa, Land-Ocean Interactions in the Coastal
Zone (LOICZ) desenvolveu uma abordagem avaliativa durante o seu projecto de
Bacias, que utilizou uma abordagem Driver-Pressure-State-Impact-Response (DPSIR)
ao longo das bacias hidrográficas costeiras, com capacidade de informar melhor
o sistema de gerenciamento costeiro. Nesse trabalho, os exemplos do
uso dessa abordagem foram apresentados e sua aplicabilidade na integração da zona
costeira e gestão de bacias hidrográficas é examinado. Observou-se que a abordagem
pode ser um instrumento fundamental para contribuir para esta forma integrada
de gestão devido a seus muitos benefícios, que vão desde a adaptabilidade, relação
custo-eficiência, capacidade de incorporar cenários e muito mais. No entanto, sugerese
que mais pode ser feito para garantir que o gerenciamento integrado da bacia
hidrográfica e da zona costeira seja efetivamente executado por tomadores de decisão.
Os principais meios identificados para alcançar esta integração seriam desenvolver um
modelo de sistema integrado de gestão ou uma estratégia baseada no quadro
de avaliação científica e unidade de gestão apresentado na abordagem sob a forma
de DPSIR e águas adjacentes, respectivamente.
The influence of river basins and their associated discharges on the coastal zone are now undeniable. As a result, the human presence and activities in these catchment areas along with natural forcing factors have been and continue to be responsible for the changes observed in the deteriorating state of the coastal environment worldwide and the associated impacts on the ecological and socio-economic benefits accrued. In an attempt to assess these discharges and understand the linkages that occur between catchment and coast, Land-Ocean Interactions in the Coastal Zone (LOICZ) had developed an evaluative approach during its Basins project that utilised the Driver- Pressure-State-Impact-Response (DPSIR) framework along the catchment-coast continuum with the ability to better direct management of the coastal zone. In this paper, examples of the usage of the approach are presented and their application in the integration of coastal zone and river basin management is examined. It was established that the approach can be a vital tool to contribute to this integrated form of management due to its many benefits not limited to adaptability, cost-effectiveness and ability to incorporate scenarios. However, it is suggested that more can be done to ensure that integrated river basin and coastal zone management is effectively executed by decision makers. The primary means identified as the way forward in achieving this integration would be to develop a blueprint integrated management system or strategy based on the scientific assessment framework and management unit presented in the approach in the form of the DPSIR and the water continuum respectively.
