As the world prepares to converge in Copenhagen, Denmark in December with the hope of arriving at a globally accepted agreement to reduce the impact of climate change on the world, there is a strong feeling that developing countries are in for a shocker.
Developed countries have declared by their actions and comments that there will be no deal protecting the interest of developing countries already bearing the brunt of climate change.
Rather than adhere to agreed positions in Bali in 2007, the developed countries are introducing new rules and insisting that those suffering the impact of climate change take up responsibilities aside poverty and other challenges they are already facing.
From all indication, the Kyoto protocol regarded today as the most binding global legal agreement that compelled developed countries to cut their greenhouse gas emission and the only hope for developing countries to get a fair deal from developed countries that caused the changing climate is heading for the rock.
The protocol provided for shared but differentiated responsibilities. Meaning that developed countries responsible for the changing climate must assist developing countries bearing the impact to adapt and mitigate the effect through the provision of funds and technology transfer.
But this may not be after all.
Sensing the implication of the moves by the developed countries in the various build-ups meetings to the Copenhagen conference, Mr. Yvo D Boer, Executive Secretary, United Nation Framework Convention on Climate Change (UNFCCC), appealed for caution and advised developed countries not to set aside the Kyoto protocol.
“You don’t throw away your old shoes simply because you are expecting a new one,” he told delegates at the recent Bangkok climate talks.
The advice came on the heels of concerted efforts by the developed countries especially the United State of America, the world leading emitter who refused to sign the Kyoto protocol and the European Commission otherwise recognized as Annex 1 parties under the Kyoto Protocol to jettison the protocol in favor of new agreement.
But Nigeria Minister of Environment, Mr. John Odey did not see any need for a new agreement saying that ``the Kyoto protocol is the most important and globally accepted agreement to address climate change.’’
The processes that resulted in the Protocol commenced in 1992 in Rio de Janeiro when Leaders of the industrialized nations met at a UN Climate Convention and agreed to stabilize their greenhouse gas emission concentration at a level that will not be inimical to the Climate System.
By 1997 the industrialized nations agreed under the Kyoto Protocol to take legally binding targets on Green House Gas (GHG) emissions by 2012. Thus, the Protocol set a binding emission target for 37 industrialized nations.
However, the Protocol has virtually failed to address the purpose for which it was signed as developed countries failed to cut their emission as well as provide funds for developing countries to tackle the impact of climate change.
Since signing of the Protocol by over 184 countries, the green house gas emission situation has taken a turn for the worse as the industrialized nations have not been able to tame their emission level. The Protocol will span out in the year 2012.
As a result of the topical nature of the impacts of Climate Change, a 2009 deadline was given two years ago at UN Climate Convention in Bali to complete the negotiation of a successor to the Kyoto Protocol. The negotiations of the successor of the Protocol are due to be finalized in Copenhagen in December, this year.
Under the Kyoto Protocol, Africa and other developing countries were exempted from any legally binding mechanism while they are to press for Climate justice under the principle of Common but Differentiated Responsibilities and Capabilities.
The Kyoto protocol despite being adjudged as one of the most important global agreements to save guard the climate was not accented to by the USA, the world leading emitter of greenhouse gases.
No wonder therefore when the USA led other developed block to the Bangkok Climate talks to demand for a new global binding, enforceable, target setting agreements that will spell out targets for both developed and developing countries.
Barely a month to the Copenhagen conference, where agreements on post Kyoto is to be reached, the developed countries have started changing pervious rules and agreements set in Bali.
This sudden departure from agreed position according to the G77+ China was a deliberate attempt by the developed countries to kill the Kyoto protocol.
The G77+ China, a leading block in the climate negotiations process representing the interest of developing countries said that the tricks by the developed countries was targeted at killing the Kyoto, their only platform to hold the developed countries accountable to the destruction they caused to the climate.
They insisted that the antics would be resisted.
Dr Victor Fodeke, Nigeria’s chief climate officer said that dropping the Kyoto would have a negative impact on ability of developing countries to tackle the menace of climate change.
He noted that the protocol protected the rights of developing countries in global efforts to tackle the challenges posed by climate change and therefore should not be thrown overboard.
“The Kyoto protocol is the only hope of the developing countries; it is the only legally binding instrument requiring developed countries to cut their emission, killing it is dashing the hope of developing countries,’’ Fodeke said.
Setting aside the Kyoto protocol because it is not enforceable is like removing traffic lights because it is not working, he added.
The Copenhagen conference therefore according to the G77+ China remained the avenue for the world to reach an agreeable premise on how to protect the interest of developing in cushioning the impact of climate change.
Inspite of the fears ahead of Copenhagen, developing countries are bent on securing a deal that would commit Annex 1 countries to contribute billions of dollars to them to cushion the threats of climate change.

The clock has tickled down to zero – Boer
As the world gathered in Copenhagen, Denmark to begin deliberation on how best to address the challenges of climate change, Mr Yvo de Boer, executive Secretary, United Nation framework Convention on Climate change (UNFCCC) has warmed that the clock has tickled down to zero.
``The clock has tickled down to zero. After two years of negotiations, the time has come to deliver,’’ he told delegates at the opening of the 15th Conference of parties to the UNFCCC.
Boer said that the time to come up with an acceptable agreement that must have three layers has come.
``The bottom layer must consist of an agreement on prompt implementation of action on mitigation, adaptation, finance, technology, REED and capacity building.
The second layer consists of ambitious emission reduction commitments and actions. It also include commitments on start-up finance in order of 10 billion US dollars per years as well as long term finance,
The third layer, or the icing on the cake consists of a shared vision on long term cooperative action on climate change and long-term goal,’’ Boer said.
He maintained that Copenhagen would only be a success if it delivered significant and immediate action.
``Developing countries desperately need tangible and immediate action on issues that would cushion the impact of climate change,’’ he added.
``The time for formal statement is over. The time for restating well-known position is past. The time has come to reach out to each other.’’

COP 15 opens with scientists debunking critics view on climate change
The 15th Conference of Parties (COP) to the United Nation Framework Convention on Climate Change opened today (Dec. 7) in Copenhagen, Denmark with the Intergovernmental Panel on Climate Change saying there existed overwhelming evidence that regions of the world are already suffering the impact of climate change.
IPCC Chair, Dr Rajendra Pachauri at the opening of the conference urged the world to neglect the recent email stealing incident at the University of East Anglia adding that it was targeted at discrediting the IPCC.
``The panel has a record of transparent and objective assessment stretching over 21 years performed by tens of thousands of dedicated scientists from all corners of the globe,’’ he said.
``Our assessment reports are based on measurements made by many independent institutions world wide that demonstrate significant changes on land, in the atmosphere, on the oceans and in the iced-covered areas of the earth.’’
Pachauri said that the global community has a moral and material responsibility to do all it can to limit the growing impacts of climate change on vulnerable societies and regions.
He noted that the absence of mitigation policies would result in possible disappearance of sea ice by the latter part of the 21st century, increase in frequency of hot extremes, heat waves and heavy precipitation.
Other impacts brought about due to the absence of mitigation policies according to him include increase in tropical cyclone intensity, extinction of 20 to 30 per cent of species and exacerbation of current stress on water resources.

African policymakers urged to speed seed to farmers
[ABUJA] African seed producers and researchers have called on policymakers to boost production of improved seed varieties and ensure that they are released to farmers more quickly.
At a policy workshop held in Abuja, Nigeria, stakeholders from industry and academia sought to unify the seed laws of different countries within West Africa to narrow the gap between supply and demand.
Recent studies by researchers at the International Institute of Tropical Agriculture (IITA) and the International Maize and Wheat Improvement Center (CIMMYT) show that current demand for improved varieties of maize seeds far exceeds supply in the region.
According to one study, the average supply of drought-tolerant, improved maize seeds in the region accounted for only one third of the total demand— with less than 50 per cent in Nigeria and only 11 per cent in Ghana — from 1997 to 2007.
Tahirou Abdoulaye, an IITA agricultural economist who led the study, said that maize seed production in the region is too low and called for a favourable policy framework to attract the private sector to the seed industry.
According to an IITA press release, maize productivity has been under threat from both climate change-related drought and delays in getting improved seed varieties to farmers.
Solving the latter problem requires a more effective, streamlined seed sector, said Wilfred Mwangi, associate director for Africa in CIMMYT's Global Maize Program.
Shehu Ado, director of the Institute of Agricultural Research at Nigeria's Ahmadu Bello University, told SciDev.Net that the gap between supply and demand was not a result of legal issues or bottlenecks in the system but of the inability of seed companies to showcase their products at the grassroots level.
He said that seed companies in the region rely heavily on the government for bulk purchases. The government, in turn, delivers these seeds to farmers, creating a gap between farmers and seed companies.
This gap has created problems of credibility and confidence, Ado said, with some farmers complaining that hybrid seeds do not perform better than freely available conventional varieties. He argued that seed companies must campaign to educate farmers on the benefits of improved hybrid varieties.
But Nnimmo Bassey, chair of Friends of the Earth International, told SciDev.Net that narrowing the gap between supply and demand will not only keep farmers dependent on seed companies but could also weaken national laws that protect the environment, opening up the region to contamination and degradation.

Experts warn of dangers for west Africa
The potentials for disaster and humanitarian crisis along the coastal state of West Africa is increasingly stark, according to disaster management experts, and countries within the sub-region need to develop programmes to manage these.
Some of the experts, gathered recently in Abuja, under a Humanitarian Future Programme (HFP) of the ECOWAS Commission and the Kings College, London, also said the possibilities of humanitarian crisis is intensifying in distinctly different ways at local and regional levels.
They point at a recent discovery that Nigeria’s waterways was under threat. Marine scientists recently found leakages from an underground pipe carrying gas through the water channel at the Tin Can inland- Liverpool Bridge.
Tunde Agboola, a professor of Urban and Regional Planning at the University of Ibadan presented some crisis scenarios that may occur in West Africa in the nearest future if contingency plans are not developed against it.
One of such scenarios was the possibility of a gas fire along the West African coast where the pipelines for the West African Gas
Pipeline is currently laid.
According to Mr Agboola, an outbreak of such fire has the potentials of displacing million of inhabitants in about five member states, leading to mass movement of people within and outside the region.
Other issues that may led to a possible humanitarian crisis in the region, according to him, include: oil spillage, gas blow out, sea surge, sudden sea level rise, water pollution and salt water intrusion.
“In the next two decades virtually all West African coastal states (12 states) could emerge as commercial oil and gas producers,” he said. “While this could constitute a driver and catalyst for economic growth and development, such infrastructure will actually increase the sub-region’s vulnerability to some type of disaster.”
He was of the opinion that should any of the crisis occur, cities along the West African coast would submerge, all economic gains of the region would be lost, the region’s flora and fauna would also be lost and underground water would be polluted.
He was not the only one with dire predictions. Mary Mye-Kamara, Director, Disaster Management Department, Office of the National Security, Sierra Leone said the West African sub-region is prone to more disasters than was hitherto imagined.
Ms. Mye-Kamara cited the River Niger, which flows through five states in the region as another potential candidate for disaster, in view of the present use of the river.
“The region was prone to health pandemic as a result of constant dumping of both solid and liquid domestic waste and industrial toxic waste into the river”, she said, adding, “this would lead to the deterioration of water quality, ground water pollution - which might also arise from mining activities -deforestation and flooding transport sediments into water bodies”.
Then there is the fear of a decrease in water volume in the region, which the governments of Nigeria, Niger and Mali are constantly talking about. A major decrease could lead to conflicts over electricity generation and increase in toxicity caused by decreasing dilution.
“There will be loss of jobs and livelihood, loss of biodiversity, displacement of fishing communities and localisation of conflicts,’’ Mye-Kamara said.
Randolph Kent, the Kings College’s Director of Humanitarian Programme however warned that the west African sub-region lacked the capacity to cope with the envisaged calamities.
“The region’s humanitarian sector faces difficulties in anticipating and responding adequately to emerging crisis,” he said. “This is due, in part, to the ways in which many organisations within the sector thinks.
“Population growth, mass migration, global warming, natural resource scarcity, toxic waste, social inequality and outmoded institutions are just some of the stark trends and factors that humankind must face; but, here in West Africa, confronting these is still a challenge”, he said.
He cautioned that the strategic capabilities of most organisations within the sub-region were uneven and that their focus is generally narrow and short-term.
An official of the ECOWAS Commission confessed as much. Mohammed Ibrahim, the Principal Programme Officer, Disaster Risk Reduction at the Commission said the region was at the cross road regarding how to prevent what could be one of the greatest humanitarian crisis of this century.
Mr. Ibrahim said that all the scenarios presented by scientists on the possibility of a possible disaster have started manifesting, as the sea current now was stronger than it uses to be.
He, however, said the Commission has the requisite organs to articulate viable options and strategies to mitigate the possible disasters.
Mr. Agboola, however, said the sub-region has to rely on indigenous knowledge to overcome any disaster. But the experts all agreed on one thing: the creation of a platform that would bring policy makers and scientists in the region together to find solutions to the envisaged crisis.

Nigeria’s plants provide cures for global diseases
Nigeria's reputation as a global centre for drug discovery has received another boost with the announcement of a research utilising tea leaves and fruit from the wild, which is showing positive results against type-2 diabetes.
The research, conducted at the University of Copenhagen and published in Alphagalileo, said the researchers at the University harvested the ingredients for the tea, totalling approximately fifty kilos of leaves and three hundred kilos of fruits, from the wild in Nigeria.
As scientists and researchers direct their attention to natural products to combat the growing global disease burden, they are discovering the wealth within Nigeria-the country with the largest moist equatorial forest and plant endemism in Africa.
Of 150,000 plant species or higher plants estimated to be present in tropical countries, about 30,000 are found in Africa. Nigeria accounts for three quarter of the African estimate.
Currently, tea leaves and other fruits from Nigeria's wild are undergoing various investigations in laboratories across the world in an attempt to find solution to some of the diseases that have ravaged humanity.
The University of Copenhagen treated the tea exactly as local healers would do: boil the leaves, young stalks and fruit and filter the liquid.
The researchers, including a Nigerian, Joan Campbell-Toftel, tested the tea on genetically diabetic mice. The results of the tests, according to the scientists, shows that six weeks of daily treatment with the African tea, combined with a low-fat diet, resulted in changes in the combination and amount of fat in the animals' eyes and protection of the fragile pancreas of the mice.
The researchers have also recently completed a four-month clinical test on 23 patients with type-2 diabetes and expressed satisfaction with the result.
The research subjects drank 750ml of tea each day. The cure appears to differentiate itself from other current type-2 diabetes treatments because the tea does not initially affect the sugar content of the blood," said Mr. Campbell-Tofte. "But after four months of treatment with tea, we can, however, see a significant increase in glucose tolerance."
From sickle cell to HIV
In 2004, some leaves from Nigeria had, against all odds, brought relief to sickle cell sufferers across the globe when researchers at the National Institute for Pharmaceutical Research and Development (NIPRD), banking on indigenous knowledge of the use of herbs, produced NIPRISAN, a potent drug for the management of sickle cell.
The drug was acknowledged by former President, Olusegun Obasanjo, at a ceremony to mark its formal launch, in 2007, as the only potent treatment of sickle cell globally. The achievement was picked up by an American company, Xechem International Pharmaceutical Company, which bought the right from the Nigerian government to mass produce and market the drug now known as NICOSAN.
The license granted the company by government was withdrawn in March 2009, following the inability of the company to meet conditions contained in the agreement regarding the availability and affordability of the drug.
Currently, NIPRD and the National Institute of Allergy and Infectious Diseases, USA, are collaborating on a research using Nigerian leaves, which is showing good signs in the treatment of Tuberculosis and HIV/AIDS.
"US and Nigerian scientists at NIPRD are currently engaged in a joint research activity to test the efficacy of remedies for tuberculosis used by traditional healers in Nigeria. It is our hope that this collaboration continues and results in better therapeutic products," US Ambassador to Nigeria, Robin Sanders, said recently.
At the Institute for Advanced Medical Research Training, University of Ibadan, research has advanced on a discovery capable of reducing the global malaria mortality, which currently accounts for over two million deaths annually.
Edith Ajaiyeoba of the Department of Pharmcognosy at the University of Ibadan said the prospect of new drugs coming out of Nigeria's wild was brighter now than ever, in view of collaboration with other international research laboratories.
William Folk, principal investigator at the International Centre for Indigenous Phytotherapy Studies, University of Missouri-Columbia, said he was optimistic that the possibility of developing a natural based drug for HIV/AIDS from the wild of Africa was high.
"In West Africa, there are well documented uses of indigenous plant spices used to treat malaria, diarrhoea, fever, pneumonia, tuberculosis, cryptococcal meningitis, oral candidiasis, herpes and other STI infections," he said.
Muhammed Gwarzo of Bayero University, Kano. Mr. Gwarzo said Nigerian herbs administered by traditional healers to HIV-infected individuals has shown that the herbals, if properly evaluated, would provide a cure to the dreaded virus.
An anti-tuberculosis drug research conducted at NIPRD, by Nneka Ibekwe and others, also showed that of the 86 plants-based recipes used by Nigerian traditional medicine practitioners for the treatment of tuberculosis, about 60 percent were active from weak to high degrees.
Inyang Uford, Director General of NIPRD, said the institute was in the vanguard of investigating plant species based on ethnomedical information. "The potentials and efficacy of Nigeria's leaves is no longer in doubt but how the country prepares itself to spearhead and encourage research into the wild to ensure it benefits from the global multi-billion dollar drug industry is what is at stake," he said.
