It is exactly two years since George Omuodo’s brutal confrontation with fishers from Uganda, an encounter that left him hospitalized with a broken arm and bruised ribs. After listening to his ordeal, one wonders where he gets the courage to go back to the lake every day.

“I have to feed my family,” Omuodo tells IPS.

Omuodo is a 28-year-old fisher from Homabay county, a place famously known for its fishing activities with its large harbor and string of fishing boats lined up along the shores of Lake Victoria.

Omuodo and most of his friends rely on fishing, a source of food and income for their families. The only problem with this humble lifestyle is that it suddenly turned risky.

Border conflicts have been a perennial problem for local authorities on Lake Victoria for a long time, which has seen some fishermen lose their lives as they participate in their trade. The infamous Migingo Island is one example of border conflict that has seen many Kenyan fishers suffer at the hands of Ugandan authorities. The fishermen complained of being harassed by the border patrols, some of whom forced them to give up their equipment, catch, and even freedom due to trespassing rules.

“The area around Migingo is good for fishing and is what drives us there. However, the Ugandan government believes that Migingo Island is their territory and that all the fish around the area belong to them. Their border patrol and fishermen have been harassing us,” Omuodo lamented.

“Since this is our only source of livelihood, we have no choice but to constantly risk our lives just to earn a living for ourselves,” he said.

Omuodo and his friends may finally have someone to watch over them as they go about their business.

Thanks to the Technical University of Kenya (TUK), fishers on Lake Victoria may soon have a drone keeping an eye on them and making sure they do not fall victim to border conflicts.

In 2018, TUK embarked on a project that saw them develop their nanosatellite dubbed “TUKSat-1,” which was aimed at monitoring security on Lake Victoria, including helping local authorities in rescue operations.

According to TUK, the satellite works by relaying coordinates, including pictorial views, to the relevant personnel, thus aiding in tracking water vessels and people who go missing on the lake.

TUKSat-1 aims to mitigate this problem by sounding an alarm whenever a Kenyan vessel drifts too close to a Kenya-Tanzania or Kenya-Uganda border.

Professor Paul Baki, the project’s lead investigator, said the nanosatellite program was a joint effort that involved disciplines from various schools such as mechanical and process engineering, surveying and geospatial technologies, aerospace, and aeronautical engineering, electrical and electronic engineering as well as physics and earth sciences.

Professor Paul Baki, the project’s lead investigator, told IPS that the nanosatellite program was a joint effort that involved disciplines from various schools such as Mechanical and process engineering, surveying and geospatial technologies, aerospace and aeronautical engineering, electrical and electronic engineering as well as physics and earth sciences.

“The TUKSat-1 program was initiated at the University in 2018 and involved collaborations between TUK and other institutions abroad,” Baki told IPS. “We were able to get funding from the Kenya Space Agency in 2020 and built the 1U nanosatellite (10cm³ in volume) between October 2020 to October 2021,” he added.

Baki said that the parts used to build the satellite were bought locally, and all the work was done in TUK’s physics laboratory.

Space exploration is not alien to Kenya, as NASA once launched a satellite from the San Marco launch site, Malindi, in 1970. Despite the satellite (dubbed Small Astronomical Satellite 1, SAS-1) not being Kenyan-owned, it did bear the Kenyan slogan “UHURU,” and the launch was a historic moment for a country that had just gained its independence. The satellite was also the first of its kind dedicated to X-ray astronomy.

Fast forward five decades later, where the University of Nairobi was able to build the first Kenyan-owned satellite (1st Kenyan University Nanosatellite-Precursor Flight) 1KUNS – PF, which was launched from the international space station in the United States.

The CubeSat, assembled by University of Nairobi (UON) engineering students in collaboration with the Japan Aerospace Exploration Agency (JAXA), was launched into the international space station on May 11, 2018. Its purpose was to carry out technological tests while recording details about the earth.

The UON got its funding, worth Ksh.120 million (about US$ 1miillion), from the joint space program between JAXA and the United Nations Office for Outer Space Affairs (UNOOSA) in 2016.

However, unlike the 1KUNS-PF, which currently floats around in space, the TUKSat-1 was launched on a drone and is meant to demonstrate the technology in preparation for more technical launches.

“Space technology and exploration will soon influence our economy and livelihood,” said Seth Odhiambo Nyawacha, a Geomatics Application Expert at Locate IT Limited. It is time Africa started producing the minds needed for technological advancements.

Nyawacha explained that Africa quickly became a consumer of space-based technology and products, which called for investments from stakeholders, especially in education and training about space technology and its exploration.

“With the development of the African Space Agency, soon to be hosted in Egypt, the continent will require home-based technicians and engineers to propel our satellites to space, ranging from communication satellites, weather forecast satellites in the wake of climate change, among other satellite types,” Nyawacha told IPS. He applauded the effort by JAXA and UNOOSA to help fund and train engineers in Sub-Saharan Africa.

A 2021 Kenyan-Spaceport report said that Kenya’s position on the equator made it a suitable center for rocket launches, and Marsabit was chosen as the site for setting up a spaceport.

The Jomo Kenyatta University of Agriculture and Technology and Moi University are other Kenyan institutions interested in space exploration.

“Kenya has shown great potential in space technology, and we should use this opportunity to set up a small-scale domestic space industry. As a country, we need to tap into the bright minds in our universities and help them propel Kenya into the frontiers of space technology,” Baki added.

Omuodo doesn’t understand much about satellites but welcomes any measure that would help them ply their trade in peace.

Water hyacinth is a weed and if not controlled on Lake Victoria, experts are concerned that the lake’s water levels might drop by 60 percent. Courtesy: CC by 2.0/Madeira Botanic Garden

By Benson Rioba
KISUMU, Kenya, Dec 19 2018 (IPS)

Currently 30 square kilometres of Lake Victoria, which stretches to approximately 375 kilometres and links Tanzania, Kenya and Uganda, is covered with the evasive water hyacinth that has paralysed transport in the area.

But scientists are harvesting and fermenting the weed, and one intrepid chemistry teacher has built a business out of it.

The presence of water hyacinth on the lake is concerning. Late last year, Margaret Kidany, one of the people involved in conserving Lake Victoria’s beaches, said the lake’s water levels might drop by 60 percent if the weed is not controlled. If it is not eliminated, it will kill the livelihoods of thousands of households that rely on the lake for an income.

However, the Centre for Innovation Science and Technology in Africa, founded by former chemistry teacher Richard Arwa, is making the best out of the invasive water hyacinth.

Funded in its start-up stages by the World Wide Fund for Nature (WWF), the innovation company, which employs six people and serves 560 households, manufactures ethanol from the weed. This is proving a cheaper source of clean fuel for many of the locals while at the same time preserving the lake.

The process they use is a simple one.

The centre hires locals to harvest the hyacinth from Lake Victoria before transporting it to their workshop for processing. Once at the workshop, the hyacinth is pretreated to remove microorganisms that might compete with the enzymes during processing.

The hyacinth is then dried and chopped into smaller pieces to reduce the surface area for efficient processing. The dried hyacinth is then mixed with water, acids and enzymes in tight closed tanks for fermentation.

After fermentation the mixture is subjected to high temperatures (80 degrees Celsius), producing ethanol and carbon dioxide and methane as final products.

“This was part of a science congress project for secondary schools and it won accolades throughout the country and we, together with my students, decided to actualise the project,” says Arwa.

Arwa is still a chemistry teacher even though he started the institution in 2016.

He adds that they initially tried to produce beverage alcohol from the hyacinth but the project was not viable. According to Arwa, alcohol requires numerous purification processes to make it consumable. In addition the taxes on the product are high.

So it is less costly to make ethanol. Arwa says the company produces 100 litres daily.

The amount is considerable for their factory, and it is sold to 560 households in Yala in Kisumu city. Arwa tells IPS that they always run out of stock.

Lyne Ondula, a mother from Yala, in Kisumu county, is a happy customer.

“Hyacinth fuel burns slower than the usual kerosene I use and doesn’t produce smoke and soot while cooking like firewood or kerosene. To me it’s much cheaper and cleaner to use, no more coughing in my kitchen when preparing food,” she tells IPS.

Ondula says a litre of ethanol retails at 70 Kenyan shillings and lasts four days. That is in marked contrast to the higher cost of kerosene, which currently retails at a national average of 100 Kenyan shillings, and lasts only two days. She says she also used to buy charcoal which was quite expensive, retailing at 100 Kenyan shilling per a 15-kilogram tin, which only lasted hours. So now she only uses ethanol, which she pre-orders.

It is a cleaner option for this East African nation that is still heavily reliant on charcoal, kerosene and firewood as a source of energy. According to a market and policy analysis by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety, while “LPG has penetrated Nairobi and higher-income households; bio-ethanol can be an attractive clean fuel for lower income households.”

Ondula’s sentiments were echoed by Sylvester Oduor, another resident from Yala in Kisumu County. He adds that ethanol fuel also produces more heat compared to charcoal when cooking.

Philip Odhiambo, energy and climate change coordinator at the WWF, says such innovations are key in harnessing the untapped opportunities of water bodies.

“There is a need to turn environmental challenges to create wealth and opportunities especially in creating jobs for our many unemployed youth,” says Odhiambo. He adds that the ethanol processing project is a viable way of managing green waste that has been a challenge in the country for a long time.

Odhiambo adds that the world is shifting towards clean, cheap energy and says there is a need to embrace creativity and tap into the energy potential of water bodies, besides the traditional sources of energy.

In addition, unlike other clean fuels, bio-ethanol can be produced domestically over time and could spur industrial growth in the sector “while delivering positive social and economic benefits,” says the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety report.

However, Arwa says accessing the initial capital of 50,000 dollars was a challenge as many financial institutions turned him away for lack of collateral. In the end he had to rely on donors like WWF to finance the project. The chemistry teacher adds that financial institutions did not have faith in the venture and were not ready to invest in the idea.

The immediate goal for the company is to expand production to 600 litres per day.

But Arwa has a five-year expansion plan that includes moving the small factory, which is about 40 kilometres away from Lake Victoria, closer to the lake to reduce costs. He hopes that once relocated, and with the support of partners, they will eventually be able to produce 10,000- 25,000 litres per day.

Arwa adds that he is looking for strategic investment partners to help in scaling up the ethanol project, reiterating that there is a huge untapped market for the product. “I usually feel bad when customers come to purchase ethanol but we turn them away. At the moment we cannot satisfy the demand,” he says.

NAIROBI, Nov 22 2018 (IPS)

In a matter of days the world’s blue economy actors and experts will converge in Nairobi, Kenya for the first ever global conference on sustainable blue economy.

From Nov. 26 to 28, participants from around the globe will meet in Kenya’s capital to discuss how to develop a sustainable blue economy that is inclusive of all.

Professor Micheni Ntiba, the Principal Secretary for Kenya’s Department of Fisheries, Aquaculture and the Blue Economy, says partnership linkages with development agencies such as the United Nations Development Programme are key to progress, but synergies need to be directed towards integrating policy and strategy for implementation.

“This will be a conference like no other, with a research and scientific symposium. It requires knowledge and hence there is the need to integrate policy and strategy for implementation as well,” Ntiba told IPS in an interview.

Wilfred Subbo, an expert in natural resources and an associate professor at the University of Nairobi, told IPS that the Sustainable Blue Economy Conference will significantly jumpstart the country’s blue economy by setting the agenda on the need to prioritise the exploitation of water-based natural resources.

He said that the stage is set for governments and private sector actors to transform the country into a robust commercially-oriented blue economy.

Just this week, on Nov. 19, President Uhuru Kenyatta launched the country’s newly-formed Kenya Coast Guard Service in Mombasa, Coastal region.

With the Kenya Coast Guard Act 2018 already in place, the mandate of the new coast guard includes controlling illegal and unregulated fishing, border disputes, and piracy as well as the degradation of the marine ecosystem.

Also on the same day, Kenyatta launched the ‘Eat More Fish’ campaign, which has Ali Ahmed is elated. Ahmed is a Malindi-based fisherman whose main target markets are in Malindi, Mombasa and Nairobi.

Government statistics shows that the current per capita fish consumption is at 4.6 kilograms, and that the president’s campaign will drive consumption to rival Africa’s average of 10 kilograms, and later attain the global average of 20 kilograms. This is part of an agenda to encourage ordinary Kenyans to both invest and reap from the blue economy based on the untapped potential in fisheries.

“Kenyans have turned to other foods like traditional vegetables and ignored fish. They say it is too expensive but this is not true. Most of the fishermen are in the business to put food on the table and nothing else,” he tells IPS.

Nonetheless, experts insist that there is still a lot more to be done towards developing a strong blue economy action plan, just as countries in the Western Indian Ocean such as Mauritius, Seychelles, Madagascar and the Union of Comoros have done.

Professor Peter Anyang Nyong’o, the Governor for Kisumu County where Lake Victoria is located, told IPS in a telephone conversation that despite huge funding towards solving environmental problems in Lake Victoria, the impact has been negligent.

The Lake Region Block is planning to host a conference early next year that seeks to discuss pollution in Lake Victoria, mainly caused by the hyacinth, the invasive plant that has paralysed commercial fishing and marine transport.

“Hyacinth has heavily affected fish life in the lake as it impedes oxygen level. We are going to discuss scientific research that seeks to bring a better solution to the hyacinth in the lake,” says Nyong’o.

And as counties from the Lake Region plan to attend the Sustainable Blue Economy Conference, Nyong’o says his county is currently working on a plan to revive the fibreglass boat-making project to curb accidents and deaths caused by the use of soft wood in making boats, which he says causes roughly 5400 deaths a year.

Experts such as Nairobi-based economist Jason Rosario Braganza told IPS that the conference offers the public and private sector an opportunity “to reinforce the narrative on the importance of a holistic approach to sustainable development through the diversification of the economy.”

Braganza says that the high-level meeting will draw attention to the responsibility that citizens have in the ethical consumption and responsible use of natural resources.

According to the Kenya Institute for Public Policy Research and Analysis (Kippra), the estimated annual economic value of goods and services in the marine and coastal ecosystem in the Blue Economy in the Western Indian Ocean is currently slightly over 22 billion dollars. Kenya’s share is approximately 4.4 billion dollars, with the tourism sector accounting for about 4.1 billion dollars.

Dickson Khainga, from the Productive Sector Division, says that Kenya’s blue world is more than just tourism and includes “the extraction of non-living resources such as seabed mining, marine biotechnology and the generation of new resources such as energy and fresh water.”

The research and policy analyst says that despite the country having a maritime territory of 230,000 square kilometres and a distance of 200 nautical miles offshore, equivalent to 31 of the 47 counties, Kenya has only explored tourism and fisheries.

According to Kippra, fisheries are by far not its most productive sector, accounting for a paltry 0.5 percent of the country’s Gross Domestic Product (GDP).

Against this backdrop, Braganza emphasises that in pursuit of the blue economy the country will need to seal its policy loopholes.

He says that the “exploitative nature of big corporations of natural resources is a threat to sustainable development.” Braganza cautions that governments “will need to be more robust and decisive in the development of institutions, and legislation to police the exploitation of natural resources.”

With shipping said to be responsible for about 2.5 percent of global greenhouse gas emissions and other pollutants, an agreement reached to reduce greenhouse gas emissions from global shipping when nations met at the International Maritime Organisation (IMO) in April this year marked a big milestone.

Feeding the globe’s projected 9.6 billion people by 2050, invigorating aquaculture estimated to supply 58 percent of fish to the global market has the potential to contribute to food security as well socioeconomic inclusion of some of the world’s poorest.

Ntoba says Africa is still blind to the rich diversity of water body resources, and that its nations should now seize the opportunity by using the upcoming global conference as a wake-up call to foment greater African partnership.

Kakamega Governor Wycliffe Oparanya, who chairs the Lake Region Economic Block, told IPS the region will seek to push for a focus to have more funding directed towards improving commercial fish farming in the counties.

So far, the government has already set aside some Ksh 10 billion to improve marine fishing in the coastal region and another Ksh 14 billion to harness commercial aquaculture in 14 counties.

“Water has been mainly used in conventional irrigation agriculture which has contributed to greenhouse gas emissions but there has to be a shift. Sustainable water use will help spur the economy and at the same time curb greenhouse gas emissions,” Oparanya told IPS.

Colvince Mubiru had heard about cage fish farming on Uganda’s lakes. The small business owner decided to try his hand at it and spent USD8,000 to set up farming cages for Nile Tilapia on Lake Victoria, expecting to reap a huge profit. But just six months into his enterprise, he made huge losses.

“It was too costly to manage so I could not continue because I could have lost all I had,” Mubiru tells IPS.

Both Uganda and neighbouring Kenya have introduced cage fish farming as a sustainable method of ensuring a steady supply of fish stock from Lake Victoria.

Africa’s largest lake, Lake Victoria, is shared by Uganda, Kenya and Tanzania. It has, according to the Lake Victoria Fisheries Management Plan III, “experienced dramatic ecosystem change over time resulting into loss of more than 500 endemic haplochromine fish species.”

Uganda began promoting cage fish farming in 2006. Cage culture encloses the fish in a cage or basket made up of floats, anchors and a frame, submerged to a depth of 10 metres.

In Uganda, small tilapia of no less than one gram are stocked in nursery cages at a density of 1,000 – 2,500 fish. These are reared to at least 15 grams in eight weeks, graded, and stocked in production cages and then reared for a further six to seven months to reach a weight of 350-600 grams before they are harvested.

Fifty-two-year-old Joseph Okeny first became a fisherman on Lake Victoria in 1997. But he abandoned wild fishing two years ago at a time when illegal fishing methods were rife and fish were scarce in Lake Victoria. He has since started a boat cruising business instead.

“You could stay on the lake for almost the entire day but could not get enough fish for consumption at home and for sale,” Okeny tells IPS.

But things have changed since Okeny stopped fishing for a living. According to the Status of Fish Stocks in Lake Victoria 2017, released in December by the NaFIRRI of Uganda, the Marine and Fisheries Research Institute (KMFRI) of Kenya and the Tanzania Fisheries Research Institute (TAFIRI), fish stocks in the lake have recovered by 30 percent compared to 2016 figures.

This also included the stock of Nile perch, a fish not native to the lake, which was introduced in the 1960s.

The increase in stock is noted also in a study by the Makerere University-based Economic Policy Research Centre (EPRC), which said aquaculture fish production in Uganda alone increased from approximately 10,000 MT per annum in 2005 to approximately 100,000 MT per annum in 2013 – accounting for around 20 percent of the total national fish production in Uganda. The study said 899 tonnes of fish were being produced in Uganda from cages in every six- to eight-month production cycle.

It also stated that there were 28 registered cage culture farmers in Uganda, with a total of 2,135 cages around Lake Victoria alone. However, KMFRI reported last month that this figure is now close to 3,696.

IPS travelled to Uganda’s Jinja district area on Lake Victoria and discovered that six cage fish farms are owned by foreign investors.

The largest of the six sells fish retail to residents around Bugungu where it has established several nursery ponds. It exports the rest to Kenya, DRC and Europe.

Asked why there were no local fish farmers with established cages on the lake, Okeny believes that adopting that technology requires financing that locals cannot afford.

Aside from the cost of the cage, which can start at USD 350, seed or fingerlings, depending on the size, can cost about USD 270, according to Uganda’s National Fisheries Resources Research Institute (NaFIRRI). There is also the added cost of feed for the fish.

Dr. Richard Ogutu-Ohwayo, a Fish Biology and Ecology specialist with NaFIRRI, has worked in Uganda’s fisheries research for over 40 years, and agrees with Okeny about the cost.

“Cage fish farming is extremely expensive and you are keeping fish in a small area. If you don’t look after them very well, it is not only the environment which is going to lose, but you are also going to lose,” Ogutu-Ohwayo tells IPS.

“It is not cheap when compared to farming in ponds. And that is why cage fish farming must be practiced as a business just like you rear broiler chicken,” says Ogutu-Ohwayo.

Pointing to an abandoned cage floating within the area allocated to fish cages of an international company, Okeny says some locals tried to invest in cages but got their fingers burnt.

“They thought that cage fish farming brings money and they also started fish farming without having enough capital to buy feed,” explains Okeny.

“These people started without consulting those who have experience. So they failed and most of them withdrew from the business. So that is why you see only one cage remaining,” says Okeny.

Researchers of the survey “Prospects of Cage Fish Farming in South Western Uganda” published in June suggest that lack of funds is the main constraint in cage aquaculture and not lack of feed and fingerlings, as has been suggested in other studies in Sub-Saharan Africa.

Gerald Kwikirizaa, one of those involved in the survey, told IPS that the results suggested that lack of funds to purchase inputs was the main constraint in cage aquaculture in South Western Uganda.

He suggested that the government could boost cage fish farming through subsidising feed cost for small-holders, especially if quality floating feed is produced locally.

Fishery development is one of the key global development goals in Agenda 2030, which comprises the Sustainable Development Goals (SDG), with countries seeking to support the restoration of fish stocks to improve safe and diversified healthy diets.

Ending hunger, securing food supplies and promoting good health and sustainable fisheries are among the topics to be discussed at the first global Sustainable Blue Economy Conference being held in Nairobi, Kenya from Nov. 26 to 28. Over 7,000 participants from 150 countries will be discussing, among other things, how to build safe and resilient communities and to ensure healthy and productive waters.

According to Ogutu-Ohwaayo, cage fish farming is common in the Great Lakes of North America. He said Africa should utilise its inland waters to produce more fish instead of relying on declining wild fish populations.

He added that if properly and systematically developed, it can be another means of food production, explaining that 21 percent of Uganda is made up of fresh water, meaning land for food production is scarce. “So we must use our water to produce food. And cage fish farming is one way of using our waters, in addition to other services, to actually produce food,” Ogutu-Ohwayo further explains.

He said Uganda’s population, which is growing at over three percent a year, cannot survive only on wild fishing, which has stagnated.

Ogutu-Ohwayo said aquaculture is the fastest growing food industry in the world and provides an option for meeting the deficit in fish production.

Uganda’s fisheries production for capture fisheries and aquaculture is estimated at 400,000 tons per year, which is not sufficient to meet growing demand. The six kg per capita fish consumption is far below the FAO-WHO recommended level of 17.5 kg.

“My conviction is that Africa should not be left behind in cage fish farming. And we have the capacity not to be left behind if we do it well,” said Ogutu-Ohwayo, also a board member of the International Association for Great Lakes Research (IAGLR), a scientific organisation made up of researchers studying the Laurentian Great Lakes, other large lakes of the world, and their watersheds.

There have been regional efforts to address the declining fish stocks through innovative technologies.

Ogutu-Ohwa told IPS that he is mobilising fellow researchers from the African Great Lakes region to develop best practices for what he described as an “important emerging production industry.”

“You must follow best management practices. Just like you would manage a zero-grazing cow. You must put in adequate management. We as scientists are doing our best to develop these best management practices,” says Ogutu-Ohwayo.

A project known as Promoting Environmentally, Economically and Socially Sustainable Cage Aquaculture on the African Great Lakes (PESCA) is part of the efforts to address social and environmental concerns related to cage culture.

It operates in Uganda, Kenya, Tanzania, Zimbabwe, Malawi and generally in the African Great Lakes. PESCA has been operational since the beginning of June 2018.

“There have been concerns that cage fish farming is going to spoil the quality of the water. We want to develop tools that would promote cage fish farming in an environmentally and social way,” said Ogutu-Ohwayo.

Meanwhile, Okeny tells IPS that the introduction of cage fish farming and the efforts by the government to fight illegal fishing seem to be paying off.“Now when people go fishing they come back with good fish because that bad practice has been controlled,” says Okeny

He has seen the negative and positive aspects of cage fishing farming. “I think cage fish farming is very productive going by the amount of fish harvested by [a cage fishing company] fish. And because of that, they are paying their workers very well,” Okeny tells IPS as he docks his boat after a busy day.

KAMPALA, Sep 23 2014 (IPS)

Over the years, Cassius Ntege, a fisherman from Kasenyi landing site on the Ugandan side of Lake Victoria, has observed the waters of the lake receding. And as one of the many who depend on the lake for their livelihoods, he has had to endure the disastrous consequences of the depleting lake.

Ntege told IPS that he first started going to the lake as teenager to fetch water for domestic use, then as a fisherman, and now as vice chairperson of the beach management unit — a body set up by the government to curb illegal fishing and stop depletion of fish stocks from the lake.

But the declining water levels of Lake Victoria have become his daily concern.Expected changes of plus or minus 10 percent from present annual rainfall totals may seem minimal, but it’s the shift in water patterns that are of concern.

“Look, where that wooden kiosk is placed was previously centre of the lake and now traders have put shops and food kiosks there,” said Ntege as he pointed to the wooden and metallic structures placed about 50 metres into where the lake waters used to be.

There are many traders operating businesses at Kasenyi landing site, which lies about 30 km from the country’s capital, Kampala. And for them, a drop in water levels means additional land to set up shop.

Ntege, like many fishermen here, believes the decline in Lake Victoria’s water levels is because of the effect of wind blowing across the waters from the land — a phenomenon known locally as “Muguundu”.

But climate experts state in the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report that a rise in global temperature is what is affecting rainfall patterns over Lake Victoria — and the worst is yet to come.

The report states that increased warming in the western Indian Ocean and precipitation over the ocean system will bring about climate extremes in East Africa and increase precipitation during the short rainy season.

Professor Hannes Rautenbach from the University of Pretoria, and one of the authors of the report, told IPS that temperatures are projected to rise by +2°C in the next 50 years, and by +2.5°C in about 80 years. This, he said, would alter rainfall patterns over Africa’s biggest fresh water lake that is shared by the East African countries of Uganda, Kenya, Tanzania.

Changes in sea surface temperatures in distant tropical oceans will strongly influence annual rainfall amounts and timing, Rautenbach said. He said expected changes of plus or minus 10 percent from present annual rainfall totals may seem minimal, but it’s the shift in water patterns that are of concern.

“The rain belt over Uganda will shift, in that areas like in the Northwest and Western regions, which have been receiving minimal rains, will receive more rains compared to the Lake Victoria region,” Rautenbach explained.

Lake Victoria, which has been receiving high volumes of rainfall, will experience a 20 percent drop in rainfall from present. This, coupled with evaporation due to an anticipated temperature rise of about 1°C over Lake Victoria, will cause a drop in water levels very soon.

East Africa is also projected to experience a change in mean annual precipitation. This will result in increased rainfall over the short September to November rainy season and it will mean that the long rainy season, which takes place between March and May, will reduce. This will negatively impact Uganda’s farmers particularly those in in areas were vital crops such as coffee, tea, cotton and maize are being grown.

Youba Sokona, chair of the IPCC Working Group III that looked at possible mitigation measures, advised that the Uganda government invest in research for varieties to withstand the changing climate.

“Crops varieties as we know them today could not withstand the change and Uganda like other East African governments has no option but to race against time and fund research into new varieties,” said Sokona.

The Ugandan government, however, say they are taking the warning seriously and are developing strategic interventions to mitigate the effects.

Dr. Anuciata Hakuza of the Ministry of Agriculture, Animal Industry and Fisheries, said strategic interventions include promoting and encouraging highly adaptive and productive crop varieties and cultivars in drought-prone, flood-prone and rain-fed crop farming systems.

She said other adaptation strategies that the government was working on include highly adaptive and productive livestock breeds, conservation agriculture and ecologically compatible cropping systems to increase resilience to the impact of climate change.

Hakuza said the government was also promoting sustainable management of rangelands and pastures through integrated rangeland management.

Uganda’s climate change policy also provides support for community-based adaptation strategies.

Dr. Chebet Maikut, one of Uganda’s negotiators to the Conference of the Parties, told IPS that there are plans to develop innovative insurance schemes, such as low-premium micro-insurance policies, and low-interest credit facilities to insure farmers against crop failure and livestock loss due to droughts, pests, floods and other weather-related events.

“Traditional finance institutions have already been reluctant to fund farming so as the risks grow even further due to climate change there will be need to develop insurance polices,” he said.

Uganda also plans to promote irrigated agriculture, and improved post-harvest handling, storage and value-addition in order to mitigate rising climate-related losses and to improve food security and household incomes.

Maikut argued that all these plans require huge investments. He said in addition to the funds that Uganda was making available out of its national budget, developed countries should also be willing to make contributions.
