Introduction to Operation OASIS

The massive waste water problem that currently pollutes our bathing waters costing £billions to process throughout the world can be used to irrigate and reforest desert coastlines to induce rainfall.

Our aim is to use the return ballast capacity of super crude carriers which currently transport sea water half way around the world at great financial and environmental cost. This ballast is discharged into the sea, often introducing invasive marine species which affects the stability of indigenous species of flora and fauna.

The E.U. is legislating against this practice and tanker operators will be forced to seek an alternative.

Operation OASIS offers an exciting opportunity for ballast water. Transporting treated waste water to irrigate and reforest arid coastlines to induce rainfall has to be the way forward.

One tanker loaded with 300000 cubic meters of treated waste water would support 57 hectares of forest for a whole year.

Reclaiming deserts to enable people to feed themselves and grow great forests will offset the carbon emissions from shipping.

With global food shortages upon us we are already feeling the strain on our pockets in the developed world and renewable resources are in rapid decline. Drought is affecting all major food producing countries and wells are running dry. Water scarcity poses major problems for us and our children. We need to act fast in order to avert a major global catastrophe.

When the mighty river Amazon dries up and it's fish stocks die it is time to take stock on how we manage our fragile environment. For more detailed information visit our website and forum at:

Planting forests may help overheated reefs

Madagascar forest
River run-off: Sediment on Madagascar's reefs is expected to increase by a further 54 to 64 per cent if 10 to 50 per cent of remaining natural forest cover is removed(Source: robas/iStockphoto)
Any benefit tropical reefs gain from reduced sediment loads caused by a drier climate will be offset by increased sedimentation due to deforestation, Australian scientists have found.
In research published in today's Nature Communications they argue that reafforestation schemes in developing countries would be more effective at protecting reefs from sedimentation damage than other climate change mitigation programs.
The team, led by Joseph Maina from Macquarie University, looked at how a warmer climate would impact sedimentation levels on Madagascar's coral reefs.
They simulated river flow and sediment supply in four river systems adjacent to Madagascar's major coral reef systems under a range of climate change and land use change scenarios.
Sedimentation and poor water quality reduce corals' ability to recover from bleaching events and other temperature related stress, and result in a deterioration in reef structure and reduction in the complexity of the ecological communities that depend on the reef.
Sedimentation levels are affected by the amount of soil removed from the hinterland then transported in rivers.
"Madadascar was used because it covers a wide range of climates from the wet north of the island to the dry south, representing a range of environments, soil types and topographies found in the global tropics," explains Dr Jens Zinke from the University of Western Australia's Oceans Institute.
"The findings are applicable to other regions such as East Africa, the Pacific and Australia."
Their research found that by 2090 all four river systems in Madagascar are likely to experience increased temperatures and rainfall declines due to climate change, resulting in decreased river flows and sediment loads impacting the reefs.

Natural erosion control

Since human settlement, removal of the natural forest cover has increased sediment supply by up to five times pre-settlement levels, so the researchers also looked at the impact reafforestation would have on reducing sediment loads being carried to the reef.
They found that sediment supply is expected to increase by a further 54 to 64 per cent if 10 to 50 per cent of remaining natural forest cover is removed, but could be reduced by up to 68 per cent if the same amount of natural forest is restored.
"Of course, there is no one-size-fits-all solution," says Zinke.
"In the drier south-west of the island where large-scale clearing has already occurred, a much larger effort is needed to create an impact.
"In the wet, mountainous north-east where the steep terrain has resulted in less land clearing, increasing cover by only 10 per cent will have a huge benefit."
But reducing land cover in the same area by only 10 ti 20 per cent will have a disproportionately large impact, he adds.
"While this study didn't take into account the impacts of rising sea surface temperatures on coral reefs, it is clear that focusing on regional land management practices will certainly help mitigate against the impacts of climate change in this region."

Extreme impacts

How applicable the model outcomes from Madagascar will be to other reefs such as the Great Barrier Reef (GBR) is uncertain, says marine ecologist Dr Britta Schaffelke, from the Australian Institute of Marine Science (AIMS).
"To my knowledge there are no quantified climate predictions regarding rainfall along the GBR apart from general predictions that climate change will make weather patterns more extreme," she comments.
"If additional land was cleared there is a high likelihood that sediment loads would increase on top of this, which would increase turbidity in the marine environment. But there is no information on what is a more important driver of future sediment runoff, extreme weather or changes in land use and ground cover.
"It would be very interesting to do a similar study for the GBR catchment," she says.
