“…Marine benefits B mar (P t ) from use and non-use values of the GBR are, in line with [5,10,13,15,19], taken to be linearly decreasing in the level of marine water pollution (see eqn (5)). While information on current economic use and non-use values of the GBR is widely available, information on the relationship between nitrogen water pollution and marine economic values is poor.…”

“…While various studies relate returns from agricultural land uses to marine economic values [5,10,13,15,19], none have linked returns from agricultural as well as residential land uses to marine economic values. In this paper we developed a deterministic optimal control approach in which we compare terrestrial benefits from population induced residential development patterns and, subsequent, marine costs from water pollution associated with these residential development patterns, to explore potential welfare gains that can be obtained from population growth.…”

“…Previous studies relating terrestrial economic land use activities, associated water pollution and, subsequent, changes in marine economic values [5,10,13,15,19], particularly focused on agricultural land use and land management for water quality improvement, though ignored urbanization of these agricultural landscapes. Consequently, they potentially underestimated returns from land use conversion and overestimated potentials for water quality improvement.…”

The Reef Water Quality Protection Plan aims at 'halting and reversing the decline in water quality' entering the Great Barrier Reef (GBR) by 2015. Population growth rates in GBR catchments are, however, amongst the largest in Australia and expected to lead to substantial changes in land use, a subsequent decline in water quality and degradation of the GBR ecosystem. This paper explores welfare gains that can be obtained from population growth in a linked terrestrial and marine ecosystem, using a deterministic optimal control approach in which we equate terrestrial benefits from population induced residential development patterns and, subsequent, marine costs from water pollution associated with these development patterns. Patterns of land use development are thereby explored using a classic urban economic model with environmental amenities, while associated water quality impacts are assessed using a water quality model. For a case study catchment in the Wet Tropics of Australia, results show that the welfare maximizing population size depends to a large extent on whether downstream costs from water pollution are taken into account. Ignoring downstream costs from water pollution leads to welfare maximizing populations that are multiple times the current catchment population. Accounting for these downstream costs, however, leads to welfare maximizing populations that are only a fraction larger than the current catchment population.

“…Goods and services of all natural systems of the Earth affect the human economy and well-being [35]. Anthropogenic impacts on coral reefs have a direct economic impact on the recreational value of reefs that can be measured [36]. Economic assessments by Cesar [37] and Berg et al [38] found that losses to coral reef tourism caused by the destruction of 1 km 2 of reef ranged between $27,900 and $100,800 USD and $5500 and $368,000 USD, respectively.…”

Depletion of water supplies for potable and irrigation use is a major problem in the rural wadi valleys of Saudi Arabia and other areas of the Middle East and North Africa. An economic analysis of supplying these villages with either desalinated seawater or treated wastewater conveyed via a managed aquifer recharge (MAR) system was conducted. In many cases, there are no local sources of water supply of any quality in the wadi valleys. The cost per cubic meter for supplying desalinated water is $2-5/m 3 plus conveyance cost, and treated wastewater via an MAR system is $0-0.50/m 3 plus conveyance cost. The wastewater reuse, indirect for potable use and direct use for irrigation, can have a zero treatment cost because it is discharged to waste in many locations. In fact, the economic loss caused by the wastewater discharge to the marine environment can be greater than the overall amortized cost to construct an MAR system, including conveyance pipelines and the operational costs of reuse in the rural environment. The MAR and associated reuse system can solve the rural water supply problem in the wadi valleys and reduce the economic losses caused by marine pollution, particularly coral reef destruction.

“…Worldwide, coral reefs face anthropogenic damage and many are affected by the same economic activities they support [4]. They face a diversity of risks, such as pollution, sedimentation, bleaching, global warming, tourism, and overfishing not only for ornamental purposes, and also tsunamis in the last years.…”

Coral reefs cover less than 0.25% of the marine environment; however their importance is not only justified by their beauty but also because coral reefs provide food and livelihood to millions of people located in communities around the world especially in developing countries. They are considered the "rainforest of the sea" (Spalding et al., 2001) because of their high productivity and specially their biodiversity. In fact, coral reefs support approximately 4000 species of fish, about 800 of reef-building corals and more than a thousand other invertebrates and sponges. Besides, a great number of species use these ecosystems as reproduction or husbandry areas. 20% of the world's coral reefs have been effectively destroyed and show no immediate prospects of recovery (Wilkinson 2004). The global threats to coral reefs began to raise alarm after the Rio World Environmental Summit in 1992 and the 7 th Symposium of Coral Reefs, starting the first calls in order to stop the decline and to provide effective protection for these ecosystems. The threats affecting coral reefs are great and the degree of damage will depend on the different areas of coral reefs locations. The threats can be classified into three groups (note that two are caused directly or indirectly by human activity):-Natural disasters, such as tropical storms, inundations, earthquakes, volcanoes, etc. To a great extent coral reefs are generally considered to have a strong potential to recover.-Global climate change, such as increments of sea surfaces temperature, rising CO 2 levels and other pollutants.-Direct human pressure, such as over-fishing, not only for food consumption but also for aquariology purposes, development of coastal zones (urban, industrial, tourism, and transport coral reefs uses).Against these threats some possible solutions can and must be developed. This paper focuses on over-fishing and the relationship between aquariology and aquaculture.
