??? Underlying questions??? Underlying questions• What are the coastal ecosystem functions
which support or provide goods and services?
• What are the relative values of coastal ecosystems services?
• How can we predict the impact of management decisions on coastal ecosystem services and related benefits and costs?
• How can we make this information available in a useful and usable form?

Categories of Ecosystem Categories of Ecosystem ServicesServices
• Provisioning services – food (including seafood and game), crops, wild foods, and spices – water – pharmaceuticals, biochemicals, and industrial products – energy (hydropower, biomass fuels)
• Regulating services – carbon sequestration and climate regulation – waste decomposition and detoxification – purification of water and air – crop pollination – pest and disease control
• Supporting services – nutrient dispersal and cycling – seed dispersal – Primary production
• Cultural services – cultural, intellectual and spiritual inspiration – recreational experiences (including ecotourism) – scientific discovery

GCLME in contextGCLME in context Highly sensitive area, where a number of ecosystems
exist in a state of balance. Interchange within and between physical, biological,
social, cultural and economic processes. Pressures from human habitation and economic
development are commono E.g. environmental degradation and deterioration of water quality,
habitat and biodiversity loss, with underlying poverty.
75% of the world’s population currently live within 60km of the coast.
Need for acceleration of capabilities for integrated coastal zone management.

"Africa’s long and beautiful coasts and the abundance of marine resources can contribute to providing economic, food and environmental security for the continent. These coastal and marine resources, like the rest of Africa’s environmental resources, continue to be exploited in a manner that does not benefit Africa and her people. This is a paradox of a people dying from hunger, starvation and poverty when they are potentially so rich and well endowed."
Nelson Mandela
Excerpt from a message to the meeting of the Advisory Committee on the Protection of the Sea, held in Cape Town (December, 1998).

GCLME initiativeGCLME initiative• Challenge
– To combat depletion of living marine resource depletion and degradation of GCLME through ecosystem-based regional actions (towards sustainable utilization of living resources)
• Goals (R3)– Recover depleted fish stocks– Restore degraded habitats– Reduce land and ship-based pollution
• Activities– Development of Strategic Action Programme + sustainable financing– Recovery and sustainability of depleted fisheries and living marine resources– Biodiversity conservation, restoration of degraded habitats & reduction in coastal
erosion– Reduction of land and sea-based pollution and improve water quality– Regional Coordination and Institutional Sustainability

Paradigm for Building Human Paradigm for Building Human capitalcapital
• Ecosystems that humans rely on for services are poorly understood, scarcely poorly understood, scarcely monitoredmonitored, and often only appreciated after they are lost.
• Active research & monitoring research & monitoring programs play a key role in providing sets of management options and potential consequences.

ConclusionConclusion• Most marine habitats now exhibit “stress”
from human activities (Noted also for GCLME)
• Explosive population growth is expected to continue in coastal regions and will “increase stress” (exacerbated by climate change).
• Science-based management strategies are essential to stem deterioration of coastal environments.

Scaling upScaling up
• Local institutional collaboration
• Regional collaboration
• Support training and research
• Collaborative research
• Developing critical mass for regional competence

ConclusionConclusion• Limited capacity and poor infrastructure are
major impediments to better management performance for coastal/marine habitats.
• Management performance constrained by limited investment in research and monitoring

politically mediated activity.
• Appropriate strategies required to disseminate scientific information
into the public policy arena
