Example text

1]. Poor people historically have lost access to ecosystem services disproportionately as demand for those services has grown. Coastal habitats are often converted to other uses, frequently for aquaculture ponds or cage culturing of highly valued species such as shrimp and salmon. 1]. However, food production in terrestrial ecosystems is higher than in marine ecosystems. ) Fish products are heavily traded, and approximately 50% of exports are from developing countries. 4]. 1]. 1]. 1]. 1]. 5] The Benguela fishery lies almost entirely within the economic zone of three countries: South Africa, Namibia, and Angola.

2]. 3]. Sewers convey human waste out of urban locations, often releasing it untreated in local waterways or coastal waters. 2]. Other pollutants, such as persistent organic pollutants, accumulate in marine mammals, seabirds, top carnivores, and predatory fish and are passed on to humans through consumption. 3]. Based on projections for food production and wastewater effluents, an increase of 10–20% of global river nitrogen flow to coastal ecosystems in the next three decades can be expected, following a global increase of 29% during the period 1970–95.

Accordingly, fish and fish products represent an extremely valuable source of foreign exchange to many countries. Traditional local fish foods are, in many cases, no longer available to local consumers due to their inability to match the prices that can be obtained by shipping the products elsewhere. 7]. 3 Why should we care about the loss or degradation of marine and coastal ecosystems and their services? ■ Coastal areas are characterized by high productivity and high human well-being but also high vulnerability to natural disasters, diseases, and pollution.
