This has exposed the Convention to proposals to adopt a number of false solutions which perpetuate biodiversity destruction, climate change and erosion of people’s rights, especially those of women, indigenous peoples and local communities. Healthy ecosystems and biodiversity are vital for regulating the climate. False climate solutions which harm biodiversity, communities and ecosystems will further destabilise the climate. They also result in the displacement of, and the loss of rights of indigenous peoples and local communities. We are already witnessing such severe impacts, as the result of false solutions which are currently being implemented on a large scale: Agrofuel (also called biofuel) crops, and industrial tree plantations, which U. N. bodies falsely refer to as "afforestation and reforestation". To make matters worse, certification schemes, standards and criteria falsely promote these damaging activities as being "environmentally sustainable". A range of other false solutions have also been proposed and some of them are already beginning to be implemented. These also threaten to have grave impacts on biodiversity, climate stability and the rights of people. They do not address the root causes of climate change but have the potential to worsen the crisis, and include. GE trees for industrial tree plantations that will be used as agrofuels and "carbon sinks" ; Ocean- "fertilisation" ( for example dumping iron particles in the sea) Carbon Capture and Storage (CCS); This includes fossil fuel combustion with CCS and bioenergy with CCS; Soil carbon sequestration schemes linked to industrial agriculture. Corporations are also promoting false solutions for climate change adaptation. Those include genetic engineering, using patented genes to induce resistance in crops to drought, salinity and extreme temperatures. At a time when rampant free market capitalism has led to financial crisis, with skyrocketing oil and food prices, market based "innovative" financial mechanisms are still being promoted to commodity nature including, carbon trading, carbon offsets, payments for environmental services, REDD, and biodiversity offsets. These "solutions" are more likely to endanger biodiversity, climate and communities. Such false solutions are really for the benefit of corporations. The real agenda behind this is to increase corporate control over land, forests, water, agriculture and biodiversity, using climate change and the biodiversity crisis as an opportunity to further these objectives. This is a new 21st century phase of colonialism. These false solutions are facilitated by false definitions and language. For example, tree plantations are referred to as "forests" and intensive industrial agriculture is Called a "Green Revolution". We call on the international negotiators and representatives of the different sectors and NGOs at CBD COP9 to oppose any intent to water down the Convention and perpetuate corporate interests. They must reject GE trees, industrial agrofuels and plantations, carbon trading and offsets; ocean fertilization, climate ready genes, another destructive "Green Revolution" and any other false solution that ignores and harms community rights, including those of indigenous peoples, degrades ecosystems, and constitutes a threat to biodiversity and climate. Who is responsible for commodifying nature
Against the backdrop of the Montreal Summit on global climate being held this week, an article on Mrican droughts and monsoons, by a University of California, Santa Barbara scientist and others, which appears in the December issue of the journal Geology, underlines concern about the effects of global climate change. Tropical ocean temperatures and land vegetation have an important effect on African monsoon systems, explains first author Syee Weldeab, a post-doctoral fellow in the Department of Earth Science at the University of California, Santa Barbara. The monsoons are critical to sustaining agriculture in equatorial Mrica. Weldeab says that man’s reduction of inland vegetation cover through deforestation and overgrazing in equatorial Africa and increases in global temperatures through the emission of greenhouse gases will likely strongly affect the African monsoon system in the future. "The weakening of the monsoon has a huge effect," says Wetdeab, "resulting in shortages of harvests and hunger." As vegetation is cleared, the land loses its capacity to retain heat and becomes cooler. As the land cools relative to the ocean, there is a larger gradient between the ocean temperature and the land causing less moisture to be pulled from the ocean air toward the land. Weldeab and his colleagues studied cores from beneath the ocean floor of the Gulf of Guinea, in the tropical Atlantic just off the coast of Cameroon, to understand the history of climate in the area for the past 10,000 years. The cores contain foraminifera, tiny plankton shells that are composed of calcium and trace elements. By studying the ratios of magnesium and calcium in the shells, the. scientists are able to correlate that information to past temperature changes in the ocean. In analyzing these records for the past 10,000 years, the scientists found three pronounced cooling periods which indicate drought. Besides the ocean records, the scientists analyzed data from four lakes that are distributed across central Africa on the monsoon belt. The three sea surface cooling periods found by the scientists correlate to records of low lake levels. These clearly were times of drought; the land became more arid. The authors state, "periods of drought likely brought about environmental hardship, triggering population migration, giving rise to changes in the modes of agricultural production, and influencing the fall or rise of civilizations." Weldeab points out that the past 50 years are marked by deforestation and overgrazing much greater than that of the past, thus disturbing the climate system that results from the coupling of sea surface temperature and vegetation cover on land. "We can’t predict how, but it is clear that this human-induced change will change the terrestrial and ocean system," he says. He notes that droughts in this region are currently occurring more frequently than in the past few thousand years, although the frequency of the droughts is unpredictable. "People in less developed countries live from rain, harvests and animal husbandry," says Weldeab. "Drought directly affects them; they run out of food for people and animals.\ Why are droughts in central Africa more frequent than in the past
