The British High Commission in collaboration with the British Council are currently hosting a climate change exhibition namely “Zero Carbon City” in Gaborone.

It started on February 11 and ends tomorrow. In the opening week, the exhibition was mounted in front of the British High Commission offices before moving to the National Assembly buildings, where it is currently showing.

The somewhat unusual but informative exhibition showcases images from 10 regions around the world captured by 10 Magnum photographers and its primary objective is to illustrate the solutions to climate change.

According to a press release from the British Council, ‘ “Zero Carbon City” is the United Kingdom’s global campaign to raise awareness about climate change around the world and what contribution the average person can make towards reversing the effect’. Looking at the exhibition, one can clearly see that it is not [continue reading]

Nobody will escape the effects of climate change but the poor in Africa will suffer the most because of decreasing food production and the heightened prevalence of diseases such as malaria, warn environmentalists, church leaders and researchers.

Another dilemma is that, “for a long time, Africans have regarded owning vehicles like in America and Europe as signs of wealth and good living. Now suddenly they are being told to give up such dreams because of global warming,” said Zenale Twala, executive director of South African Non-Governmental Organisations Coalition (SANGOCO).

She was speaking at a SANGOCO workshop in Johannesburg on the effects of climate change on the poor this week (May 15).

“When I see the price of basic commodities like maize increasing, I see the writing on the wall,” Bishop Paul Verryn of the Methodist Church told the workshop. He is particularly concerned about a plan to turn some of South Africa’s arable agricultural land into producing biofuels. “Turning the land into producing biofuels could exacerbate poverty.”

South Africa’s planned production of biofuels from crops such as maize, sunflowers and sugar cane “can play a role in improving energy supply for the poor as long as they are grown by small-scale farmers and rural people”, said SANGOCO.

SANGOCO is opposed to the plan by the government and business to use some of South Africa’s arable land for maize for biofuels while more than 1.2 million South Africans suffer from malnutrition and 14 million are vulnerable to food insecurity.

Almost half of households in South Africa - 43 percent — suffer from food insecurity. Ten percent of children under nine are underweight; whilst 1.5 percent are classified severely underweight, according to official figures.

Emissions of carbon dioxide can largely be attributed to the transport sector. “Yet we are [continue reading]

Botswana: Drought - Has Our Early Warning System Collapsed?

Posted to the web 16 May 2007

It is interesting to learn that President Festus Mogae is likely to declare the current year yet another one of drought. While it is very much in order for the President to declare a drought year, it is doubtful whether, as a nation, we have to wait for him to tell us that we are yet on a drought. The signs have been clear that this was going to be a long spell of drought, any way.

The limitation of the arrangements that the country has been on disaster management are also clear, thus making the very process of dealing sufficiently with the natural causes of drought difficult. Perhaps it is not far fetched to say that the country’s early warning systems have ground to a halt.

The picture that emerges is that every time the country is faced with drought, the preparedness is not up to the match. Why should the nation wait for the President to make an announcement when it should have been plain to all of us that we should take appropriate contingency measures to deal with the crisis?

Measures such as the Early Warning System should tell us whether drought is coming or not. For example, just in the recent rainy season, places such as Gaborone and other parts of the country did not receive significant rainfall. But what message did each one of us make of the situation? Nothing. We have to wait for the President to tell us that we are in a drought situation!

Another problem arises from the limitations of the interventions targeted to mitigate drought and its effects. The interventions are only made when there is already a drought year. We should have learnt enough lessons from the drought spells that the country has gone though in the past that our interventions are timely. For Botswana, drought should be treated more as a permanence than an event. Some of the interventions are such that when they come, they clash with the next ploughing season, resulting in some people preferring to work on drought relief projects instead of working on their fields.

Water management remains major concern in Sadc - expert

source: The Herald, Harare

From Tsitsi Matope in MAPUTO, Mozambique

WATER management issues remain a major concern to the southern African region where the bulk of the countries are grappling with the scarcity of the precious liquid and poor crop production following the poor rains received during the just-ended rainy season, a regional water expert said yesterday.

World Conservation Union regional water programme co-ordinator Mr Lenka Thamae who is based in Harare said governments from the southern Africa region should try and improve on current water management policies and strategies to sustain all water influenced sectors.

Mr Thamae was speaking yesterday at the five-day Integrated Water Resources Management Stakeholders’ Dialogue underway in Maputo Mozambique.

More than 40 representatives from the 14 countries that make up the Southern Africa bloc are attending the dialogue, which has drawn senior government officials from the water, health, tourism and agriculture sectors.

Mr Thamae said without proper regional collaboration on proper water utilisation and vibrant river and dam management, the region was under threat because most of the water it has and depends on is shared courses.

“The region is vulnerable to climate change, which is bringing prolonged dry spells and causing flooding, especially in Madagascar, Mozambique, parts of Zambia and Zimbabwe. We need to find ways of dealing with the problems of limited capacity and co-ordination among water oriented institutions,” Mr Thamae said.

This year’s theme is focusing mainly on “watering development,” a concern raised at last year’s water conference held in Namibia.

Water experts had said there was need to increase applications of water demand management and focus on developing water resources to improve water supply in critical sectors such as agriculture.

This year’s dialogue is unique in the sense that local communities who utilise water to support their families through embarking on community gardens and fishing are also attending the conference.

Their experiences and concerns will be noted and discussed at other high level regional meetings.

Water experts said it was important for those at the grassroots levels to understand the Integrated Water Resource Management concept as it promoted co-ordinated development of water and land resources usages to maximise economic and social benefits without compromising sustainability of vital ecosystems.

By promoting a broad stakeholders participation, the water experts said they were optimistic that the water challenges facing the region would be dealt with as they would have made strides to empower communities to recognise water as a finite but essential resource.

“Realising the economic value of water will see communities implementing proper management of catchment areas and wetlands and be able to implement conjunctive use multiple sources of water, which include surface, ground and the rain,” Mr Thamae said.

The participants will on Thursday also visit the Umbeluzi River Basin, which supplies water to Maputo.

Mozambique, according to the head of the IUCN programmes, Mr Ebenizario Chonguica, is still in the process of enhancing its knowledge system in water and land usages.

Though it boasts of many water resources, which include the Indian Ocean, Mozambique needs to research more on how it could maximise the benefits at its disposal and share the resources with some neighbouring countries.

“There is a lot of work that needs to be done in terms of managing the water resources like for instance they can be developed into vibrant hydropower stations, which could benefit the rest of the region. The management of these resources should, therefore, be a concern for all people in the region to ensure we do not continue losing river sediments or prevent siltation,” Mr Chonguica said.

Mozambique is also susceptible to floods being down stream of Madagascar, a country in southern Africa region always hit by tropical cyclones.

Maputo is situated close to the sea and there are always fears that a better part could be destroyed if a strong storm brews on the expansive water resource.

Mr Chonguica said stakeholders were aware of such possibilities and had set up a disaster preparedness institute, which is always monitoring weather events.

“We are now moving towards being pro-active to minimise the impact of floods. We can not be 100 percent effective and of course lives could be lost sometimes and always property destroyed,” Mr Chonguica said.

The dialogue is also expected to discuss issues regarding national responses to water challenges, which include the formulation of water authorities in various countries, the role they are playing and whether there are elements of the IWRM concept in how they are managing water issues.

The experts will also from their discussions see if there is need to improve on the IWRM concept to address certain problematic areas.

Panel: Climate change will hurt Africa

BRANDON REED

JOHANNESBURG, South Africa - Global warming isn’t just a matter of melting icebergs and polar bears chasing after them. It’s also Lake Chad drying up, the glaciers of Mt. Kilimanjaro disappearing, increasing extreme weather, conflict and hungry people throughout Africa.

According to a landmark effort to assess the risks of global warming, Africa - by far the lowest emitter of greenhouse gases in the world - is projected to be among the regions hardest hit by environmental change.

“We never used to have malaria in the highlands where I’m from, now we do,” said Kenyan lawmaker Mwancha Okioma, at a briefing on climate change at the Pan African Parliament Monday.

The new environmental committee, headed by Okioma, raised concerns about the severity of climate change on Africa and called for those responsible to help reduce its effects.

“Planes used to take people through Kilimanjaro to see the snows, now it’s only at the very top. We are asking the ones in North America and Europe who are producing the pollution to help us,” Okioma said.

By reviewing four years of research on projected climate change in Africa, scientists with the U.N. Intergovernmental Panel on Climate Change got a nuanced view of possible scenarios and assessed how these scenarios could play themselves out in a continent already stressed - water and food insecurity, infectious diseases, conflict, poverty.

“There’s a whole suite of indicators which with climate change would undoubtedly make Africa one of the most stressed regions,” said Coleen Vogel, an environmental expert at South Africa’s University of Witwatersrand and lead author of a chapter on Africa being released this month by the Intergovernmental Panel.

East African scientists have united in a bid to protect the region’s ecology and biodiversity from changing climatic conditions, the invasion of pests, and unsustainable development.

The newly formed Ecological Society of East Africa (ESEA) involves 200 of the region’s scientists, who will lead scientific investigations and provide policy advice on these threats.

Ecologists from Burundi, Ethiopia, Kenya, Rwanda, Sudan, Tanzania and Uganda met in Nairobi last week (3-4 May) to set up the society’s secretariat and elect its interim officials.

Eric Mugurusi, director of the environment in the Tanzanian Office of the Vice President, said protecting the region’s ecology is important.

“The ecological systems are the basis for economic activities. Tourism, fisheries and agriculture depend on ecological stability,” he said.

ESEA will, amongst other goals, aim to address ecological threats to the region, such as the emergence of alien species like ferns and other weeds that destroy pasture, encroach on agriculturally productive land and raise the cost of maintaining existing transport networks.

The Mathenge weed, for example, was introduced to east Africa to combat desertification by providing vegetation cover in arid lands. But the plant has proved poisonous and displaced 300 other plant species in Kenya and Tanzania.

The weed formed bushy paths and clogged access to highways, increasing the cost of maintaining roads in the remote countryside. The plant was also responsible for livestock deaths in local communities in Kenya.

Climate change action needed now

South Africa needs decisive policy shifts both to cut greenhouse gas emissions and to beef up investment in climate-friendly technologies if it is to avoid the worst effects of climate change, says Environment Minister Marthinus van Schalkwyk.

Reacting to the release in Bangkok of the third report this year from the Intergovernmental Panel on Climate Change, Van Schalkwyk said on Sunday the central message was one of urgency, leadership and ambition.

“We need to act quickly, we need to make decision policy shifts and we need to be ambitious in embracing technological options,” he said.

The key message was that the world had just a few years to act to avert the worst impact of global warming. Delays in reducing greenhouse gas emissions would have devastating effects.

These emissions had grown by 70 percent since 1970 and could rise another 90 percent by 2030 if no action was taken.

Van Schalkwyk said many technologies to cut emissions already existed [continue reading]

Climate change to cost Western Cape billions

April 26 2007 at 01:34PM

By Philda Essop

Cape Town - The Western Cape is likely to have to fork out billions of rand over the next 20 years to limit and adapt to the effects of climate change.

The Environmental Affairs Department’s director for strategic and environmental management, Mark Gordon, told the Cape Argus on Wednesday that the money would be needed for new power stations, desalination of sea water, new dams, changing crop cycles, finding new export revenue streams and the effects on housing and coastal development of possible rising sea levels.

Other expenses would include sanitation and communicable diseases, he said.

“When it gets warmer there is always the likelihood of more disease, so more money will be spent on healthcare. Introducing other forms of renewable energy will be more costly than the cheaper coals we are using.”

Gordon said that doing nothing would cost more in the long run.

“Plans to reduce the effects of climate change are now [continue reading]

Kilimanjaro: Ice fields at the equator are a huge tourist draw


A fresh assessment suggests the famous ice fields on Africa’s tallest mountain will be around for decades yet.
Recent concerns that climate warming would rob Mount Kilimanjaro of all its glaciers within 20 years are overly pessimistic, say Austrian scientists.

Their weather station data and modelling work indicate the tropical ice should last well beyond 2040.

Precipitation and not temperature is the key to the white peak’s future, the University of Innsbruck-led team says.

“About five years ago Kilimanjaro was being used as an icon for global warming. We know now that this was far too simplistic a view,” said Thomas Moelg.

“We have done different kinds of modelling and we expect the plateau glaciers to be gone roughly within 30 or 40 years from now, but we have a certain expectation that [continue reading]

Africa: Climate Change Will Impede Development, Warn Experts

Among the most compelling evidence of the onset of climate change is the impact on the world’s glaciers and ice sheet

NAIROBI, 10 April 2007 (IRIN) - Africa needs urgent assistance to adapt to climate change if its people are to thrive in the 21st Century, a senior United Nations official said on Tuesday.

“Response to climate change is interdependent and Africa cannot cope on its own; this makes it the main test of people working together to adapt to the impacts of climate change,” said Achim Steiner, Executive Director of the UN Environment Programme (UNEP).

Speaking during the launch of a regional report by the Intergovernmental Panel on Climate Change (IPCC) titled: ‘Climate Proofing Africa, Key Challenge for the Continent’, Steiner said human activities were clearly influencing climate change.

The report predicts that an increase in greenhouse gas emissions will see up to 1.8 million more people in Africa without sufficient clean water, an increase in arid and semi-arid lands, poverty and an increase in pandemics like malaria, cholera and Rift Valley Fever (RVF).

“Temperatures are due to increase by up to 5.8 degrees [Celsius] before the end of the century in arid or semi-arid areas that are prevalent in Africa. The implications of such an increase are multiple and include: rise in sea-level, increased droughts or floods, less access to water which will beget health and agricultural problems,” said Anthony Nyong, senior programme specialist with Climate Change Adaptation in Africa, during the launch.

He urged African governments to work together and incorporate climate change issues in their regional policies. [continue reading]

BRUSSELS: In a sign of shifting politics over global warming, leading scientists said Friday that China was among a group of nations that had sought to water down a major report on climate change, while they credited the United States, long a skeptic about climate change, with sometimes playing a helpful role.

Capping four days of debate between scientists and representatives from more than 100 governments, Martin Parry, co-chairman of the team from the Intergovernmental Panel on Climate Change, said the effects of climate change were widespread and measurable, with much more to come.

“We’re no longer arm-waving with models,” said Parry. “This is empirical information on the ground.” He added that [continue reading]

Climate Change Affects Botswana

STAFF WRITER

SELEBI-PHIKWE: Botswana is affected by the changes in global climate as evidenced by extreme temperatures, recurrent droughts, floods, severe thunderstorms and strong winds.

Selebi-Phikwe Mayor Benjamin Bagayi said this during the World Meteorology Day commemoration last Friday. He said that Botswana suffered prolonged droughts during the 1960s and 1980s, which were worsened by the El Nino in 1982/3. He said these droughts slowed down the country’s construction industry and impacted negatively on food security.

“The country is currently suffering from severe drought which will result in water use restrictions.” However, he applauded the efforts by the Department of Meteorological Services by trying to create awareness amongst Batswana on issues of climate change and the likely impacts. He said the other problem was layer depletion.

Bagayi was grateful to note that in partnership with the United Nations Environmental Programme (UNEP), the German Technical Agency and [continue reading]
