Climate Change

Chaotic Construction Fuels Climate Change In Zimbabwe

Harare — His house stands out in the midst of water, with the entire driveway concealed under water, apparently with nowhere to step on, yet for 15 years, 50-year-old Jimson Ruvangu in Westlea suburb in the Zimbabwean capital Harare, has managed to evade censure from the city’s local authorities.

Ruvangu claims he acquired the piece of land on which he built his home through a local housing cooperative.

But climate change activists, even as many like Ruvangu are apparently getting away with murder, warn that illegal construction of homes and commercial buildings is fueling climate change impacts across Zimbabwe.

Yet, many like Ruvangu even as they dwell in the midst of wetlands, he (Ruvangu) is happy that he has somewhere to lay his head.

“I have a home; that is what matters. Whether it was built illegally or not, that is another matter, but look, I am nearing two decades living here and nothing has happened to me,” Ruvangu bragged.

For climate change activists here like Happison Chikova, it is illegal construction that particularly fuels climate change impacts across this Southern African country.

“The haphazard construction of houses in the major cities and towns in Zimbabwe has contributed immensely to climate change in Zimbabwe. The unplanned housing schemes has contributed to high emissions of green-house gases into the atmosphere due to rampant deforestation and destruction of wetlands,” Chikova told Ubuntu Times.

As construction occurs on undesignated places, according to Chikova, ‘the destruction of biodiversity and the ecosystems reduces carbon sequestration as huge amount of carbon dioxide is lost into the atmosphere as vegetation acts as carbon sinks.’

That in fact has not moved illegal urban land occupiers like Ruvangu who claim nothing will move them, but in the eyes of climate change experts like Chikova, many like Ruvangu have brought more harm than good.

“The haphazard construction of houses in urban areas is resulting in increasing the heat in the cities, thereby creating heat islands. This is because the houses are not built according to the city standard as well as following green cities foot prints,” said Chikova.

He (Chikova) also said as construction is often done illegally, ‘the destruction of wetlands has affected local climate as the wetlands are responsible for cooling the environment hence increase in temperature.’

Apart from being a holder of a degree in environmental studies from Zimbabwe’s Midlands State University, Chikova is a student at the University of Edinburgh in the UK studying global food security and nutrition.

For Harare Wetlands Trust, a conservation group here, disorderly constructions across Zimbabwe’s wetlands have also fueled climate change impacts.

“Construction covers wetlands with hard surface. The water can no longer seep into the soils to be stored. So, water runs off and floods on hard surfaces downstream. It is not available underground to keep streams flowing during droughts and dry seasons and we blame climate change when we changed a crucial landscape and contributed to climate change,” Selestino Chari told Ubuntu Times.

To him (Chari), ‘it is effectively an ecocide to build (homes) on something that supports us when we can build elsewhere. And where will all this built-up area get its water from after it runs off the hard surface down to the sea?’ Chari said.

Even the country’s top academics have weighed in, apparently irked by the growing climate change impacts emanating from rife construction on undesignated points here.

One such intellectual is Professor Johnson Masaka, the executive dean at the Midlands State University’s department of Land and Water Resources Management, who has spelt out the harm wrought by the chaotic constructions.

“Firstly, the unplanned constructions will necessarily require that trees, bushes and grasslands are cleared on construction sites. The vegetation that fixes carbon dioxide, a greenhouse gas or global warming gas, in photosynthesis is destroyed in the site,” Masaka told Ubuntu Times.

With haphazard construction all over Zimbabwe’s towns and cities, Masaka said climate has had to suffer the results amid wanton cutting down of trees as people in illegally built homes have no access to electricity.

“Provision of electricity in such haphazard settlements is almost impossible due to legal requirements; so, people resort to use of fuel wood. Upon burning, the wood releases a series of global warming gases such as carbon monoxide and methane into the atmosphere where they cause warming of climates,” said Masaka.

But many urban dwellers like 56-year-old Hector Ruvende based in Masvingo, Zimbabwe’s oldest town, see nothing amiss dwelling on a wetland upon which he built his home two decades ago.

“Electricity will be connected to my home one day; what matters is that I have a roof above my head; of course, we use firewood which we buy from wood poachers,” Ruvende told Ubuntu Times.

Such actions by Zimbabweans like Ruvende, to Professor Masaka, ‘participate in loading the atmosphere with global warming gases.’

Yet even climate change activists in Zimbabwe like Kudakwashe Makanda who is the programmes manager for the Youth Initiative for Community Development (YICD), a youth civic organization, blame disorganized construction for worsening climate change impacts in the country.

“I think you understand that most local authorities have been allocating housing land on wetlands mostly; this then undermines the crucial role that is played by wetlands which is to service the water sources that we do have across the country and also to clean the water; by constructing houses on wetlands, it means the water being reserved or kept there will stop being available,” Makanda told Ubuntu Times.

For Makanda, chaotic urban construction of homes has in fact brought more harm than good.

“Cutting down trees so as to pave way for residential areas also reduces the amount of vegetation that is necessary to supply the atmosphere with water vapor and that alone then leads to less rains being experienced,” said Makanda.

To Makanda, ‘the major challenge is that most local authorities are prioritizing development at the expense of environmental consciousness and the way that they are apportioning the land is not being done in a well thought out manner.’

Yet for independent climate change experts like Gilbert Musungwa in Zimbabwe, corruption in the country’s urban local authorities has fueled illegal construction of homes, subsequently leading to noticeable climate change impacts.

“In other sectors like the construction industry, the issue remains a sub-issue and often overshadowed in the offices; whenever there is an intention to have some infrastructural development, oftentimes environmental impact assessments (EIA) are requested. It boggles the mind how some developments pass the required EIA,” Musungwa told Ubuntu Times.

Train Accident In Tanzania Highlight Country’s Vulnerability To Extreme Weather

Dar es Salaam, Tanzania — The fatal accident of a passenger train which derailed on Sunday, January 3rd near Tanzania’s capital city, Dodoma, killing three people while injuring 66 highlights growing danger and the vulnerability of the railway infrastructure to extreme weather, a local expert has warned.

The accident, which happened at Kigwe village, about 508km from Dar es Salaam, highlights structural weakness of the aging central railway line built in the 1960s.

Climate Change Adaptation

Wilbard Kombe, Professor of Urban Land Management at Ardhi University urged Tanzania authorities to devise measures for climate change mitigation and adaptation to contain natural hazards that frequently destroy railway networks.

According to Kombe sudden torrential rains have the capacity to wash away track beds and make railway crumble.

“We need better strategies to increase the reliability of the rail infrastructure and prove to our neighbors that our train operations get on uninterrupted throughout the rainy season,” Kombe said.

Train transportation, which is heavily relied on by Tanzanians is highly susceptible to flooding triggered by the worsening impacts of climate change.

Recurring Flood Spells

The floods frequently wash away the railway infrastructure forcing trains to derail, and disrupt operations, officials said.

According to Kombe, wet and windy weather can significantly impact the rail network.

“There is the potential for damage to rail tracks caused by debris or fallen trees which could severely impact passenger services,” Kombe said.

Flood water in particular can block the lines with debris, silt, and mud making its way into the track, he stressed.

“The damage that flood water can cause to infrastructure may lead to on-going repairs that can last for weeks even months,” he told Ubuntu Times

New Lease Of Life

While the east African country is determined to give its aging railway network a new lease of life through the construction of the Standard Gauge (SGR) railway along the central corridor, analysts say such efforts are likely to be hampered by the risk of heavy rains hazards.

As part of its broader push to improve the infrastructure for road and railway transportation, Tanzania is implementing multiple projects to tap the potential of a thriving trade with landlocked neighbors.

Landlocked Neighbors

Perched on a lush landscape with vast minerals, agricultural resources, and potential for world class tourism, the east African country plays a pivotal role as a transport hub for its landlocked neighbors including, Rwanda, Burundi, and Zambia, providing unrivaled opportunities for cross-border trade.

As Africa experiences a huge economic recovery with strong growth projections, rail transport is expected to play an important role in the conveyance of freight over long distances. However, the condition of the existing railway networks in Tanzania is poor.

Binilith Mahenge, Dodoma Regional Commissioner, said depending on budgetary allocation the government is determined to build strong rainwater drainage system along major road and railways to withstand the forces of floodwater.

However, critics say railway operators in Tanzania are totally unprepared to deal with the powerful forces of extreme weather which frequently wreak large swathes of rail infrastructure and halt train operations.

Overwhelmed Drainage Systems

Heavy rain can overwhelm the drainage systems on the railway, technically known as culverts and make flooding more likely, experts warned.

“Piles of wet earth, mud, and debris spreading into the track can be a huge problem,” said Kombe.

Climate change is projected to increase the frequency and intensity of extreme weather events thus increasing risks on the railway.

Kombe urged Tanzania authorities to devise a long-term plan to assess flood risks to the railway and identify earth works likely to be flooded thus building a flood-warning database for monitoring the area.

“There are many ways to prepare for and reduce the possibility of flooding, such as deploying flood defense system such as inflatable barriers and clearing branches and leaves from ditches and culverts near the railway,” he said

While local experts had always referred to historical climate data when designing railway transport systems, to help them withstand drainage storms especially extreme weather, Kombe said such data is no longer reliable due to climate change.

A Million Livelihoods In Kenya, Tanzania At Risk As Mara River Fish Driven To Extinction

By &

Rorya, Tanzania — At Koryo village, in Tanzania’s northern Rorya district brightly dressed women flock to the river with piles of their laundry bags.

Some of them walk for hours just to be on time to access an increasingly endangered resource: water.

Nestled on the Tanzanian border with Kenya, the village receives enough rainfall, but for some reason, the water doesn’t meet the growing needs of the inhabitants.

“We have lost six permanent rivers in the past two decades,” says 57-year-old Andrew Nyamaka a local resident, adding “When the dry season sets in finding water is a constant struggle.”

Endangered Livelihoods

Depleting water resources in this impoverished village highlight the worsening plights of people in the wider Mara basin whose lives are increasingly endangered.

The livelihoods of 1.1 million people in Kenya and Tanzania are on the brink as fish are driven to extinction, according to WWF.

A new report by the wildlife NGO says the trans-boundary river is threatened by among others, unsustainable farming, deforestation, mining, illegal fishing, and invasive species.

The report, which examined freshwater biodiversity in the river basin identified 473 native freshwater species including four mammals, 88 water birds, 126 freshwater associated birds, four reptiles, 20 amphibians, 40 fishes, 50 invertebrate species, and 141 vascular plants.

According to the report, some fish species including; Niangua, Singed and Victoria tilapia are critically endangered and increasingly threatened by the Nile perch that had been introduced in Lake Victoria.

Birds Too At Risk 

The report also listed some bird and fish species including Madagascar pond-heron, grey crowned crane, and killifish as endangered whereas the shoebill, and some crab and freshwater mussel species, are described as vulnerable.

Amani Ngusaru, country director, WWF Tanzania said the river is under huge pressure from destructive human activities such as unsustainable agriculture, tourist facilities, water pollution, and land degradation.

“Several aquatic species have not been seen for many years and may be extinct before they have been studied,” he said in the report.

His remarks were echoed by Yunus Mgaya, professor of Marine Biology at the University of Dar es Salaam, who concurs with the report saying that the farming and irrigation activities have seriously affected the river flow and ecological balance of the basin.

“The basin is facing a bleak future that put the river at risk, unless deliberate efforts are taken to reverse this trend many livelihoods will suffer,” he told the Ubuntu Times.

As the world is grappling with rapid decline of freshwater biodiversity due to the changing weather patterns, WWF is calling for joint efforts to preserve critically endangered freshwater biodiversity.

Tourist Attraction

The Mara basin, which sprawls across 13,750 sq km is home to many plant and animal species. Known for its great spectacle of wildebeest and zebra migration, the area attracts tourists who inject millions of dollars in Kenya and Tanzania economies.

Tourism plays a pivotal role in the economies of both countries. The sector provides direct employment to thousands of people and contributes roughly US$1 billion to the economies of Kenya and Tanzania.

The Maasai Mara National Park, for instance, attracts more than 300,000 visitors every year, bringing roughly Kenyan Shillings 650 million, or 8 percent of the country’s total tourism earnings.

Water Abstraction

As the only water source in the dry season, the Mara River, which runs through Maasai Mara Game Reserve in Kenya and the Serengeti National Park in Tanzania, has experienced erratic flow, partly due to the abstraction of water for irrigation and hydropower.

The basin and its adjoining wetland is under increasing strain due to farming, overgrazing and irrigation activities, which have affected the quality of water and the flow of the river.

Fishing and agriculture are the main economic activities and sources of livelihood for many people in the Mara basin. More than 80% of the population in communities around the swamp are engaging in farming and fishing.

Local residents both in Kenya and Tanzania rely on fish and other aquatic foods harvested in ponds, lakes, and rivers to get healthy diets for their families and livelihoods.

Rose Kasoka, a 44-year-old fish vendor travels far to buy a stock of dried fish to sell at retail price.

“I don’t realize much profit because I don’t often get Ningu which most customers love,” she said.

Reversing Deforestation

In the village of Ikoma, Waridi Mwita, a 51-year-old farmer, is busy packing soil into plastic seedling bags. She’s trying to plant trees in the hope to restore forest cover that has long been destroyed.

“People are very busy making charcoal, they don’t realize they are destroying the environment and are preparing for their own extinction,” Mwita told the Ubuntu Times.

Deforestation especially in the Mau Forest and dry-season soil erosion have exacerbated the effects of drought as the water level drops to its lowest ebb, consequently affecting humans and wildlife.

Indigenous forests have been logged for timber and charcoal burning.

“One of the reasons trees are cut down is to produce charcoal, which is a lucrative business in these communities,” Mwita said.

In this tiny village, perched on groves of banana trees, water was once plentiful. But due to spells of drought, most small rivers have dried out.

“When I was young, my parents never experienced water problems that we experience today,” she said.

According to WWF report, the quality of water in the Mara River is also affected by domestic waste whose disposal has negatively affected aquatic life by reducing fish spawning sites and even clog their gills.

“Heavy metal contamination from mining activities is posing a huge risk to ecology and people,” the report warned.

Zimbabwe Farmers Embrace Conservation Agriculture To Beat Effects Of Climate Change

Marange, Zimbabwe — It is a windy day in Marange, Chanakira village. Small clouds scuddle the blue sky giving it a blurred look. About 110 kilometers southwest of Mutare, Norah Mwastuku (48) a subsistence farmer sits at the verandah and contemplates when the first rains will arrive. 

She anxiously looks at her fields, decorated with mulched holes.

Mwastuku is one of the farmers who have embraced the Pfumvudza program — a concept where crops are planted on zero tillage in a bid to conserve water and inputs on a small piece of land.

She is enthusiastic about the program and is looking forward to the new season. 

“I have already dug holes in a 39 meters by 16 meters piece of land. This coming season I am planning to grow maize,” the mother of four told Ubuntu Times.

This area does not receive much rain and farmers like Mwastuku rely on boreholes to water their fields. The soils are tired too. 

While the government is currently popularizing the Pfumvudza program, Mwastuku is used to it. In the season 2019/2020, she grew maize and sorghum at the same size of land as part of Pfumvudza.

“I had a good harvest. This is what we are surviving on as a family,” she said. The farming concept is increasingly becoming popular among farmers in areas that receive less rainfall. 

Lilian Murangariri (50), a small-holder farmer from Headlands, about 140 kilometers from the capital Harare says Pfumvudza has less labor.

“Last year I grew orange maize and white maize in a half-hectare piece of land. I was amazed with the harvest. As a farmer you do not have to stress about using cows for tillage as this is zero tillage,” she told Ubuntu Times.

The mother of three says Pfumvudza is economic and can be practiced by farmers who do not have enough farming machinery. 

“The holes and mulch conserve water. I can still harvest my crops even if there is poor rain. I also use less inputs such as fertilizer,” said Murangariri.

Mwastuku and Murangariri are some of the over 9,000 people who have embraced Pfumvudza with the support from the Zimbabwe Livelihoods and Food Security Programme (LFSP).

The LFSP, which is funded by the Foreign, Commonwealth and Development Office (FCDO), is managed by United Nations’ Food and Agriculture Organization (FAO) and implemented by Welthungerhilfe, Practical Action and World Vision.

It is aimed at reducing poverty, targeting 250,000 rural farming households through improved food and nutrition security and incomes in 10 districts in Zimbabwe.

LFSP trained over 50,000 farmers from their clusters in Manicaland, Midlands, and Mashonaland Provinces in 2019.

For the past half a decade Zimbabwe has been having incessant droughts and floods which, according to experts, are caused by climate change. 

Nearly 8 million people, about half of Zimbabwe’s population, are food insecure, according to the United Nations’ World Food Programme.

The southern African nation, which was once the breadbasket of the continent, will import an estimated 1.1 million tonnes of grain in the 2020/2021 marketing year to meet demand, according to the FAO.

This Pfumvudza concept which was spearheaded by FAO last season in Zimbabwe has been adopted by the President Emmerson Mnangagwa led government in the 2020/2021 season targeting nearly 2 million households, about 10 million people. 

The government is supporting these farmers with inputs.

Prudence Mucharwa, a small-holder farmer in Chihota near Marondera, about 70 kilometers from the capital Harare, said she is new to the concept.

“I joined Pfumvudza a bit late. I met an Agritex officer who explained it to me. The Grain Marketing Board will loan me inputs and I will pay back with maize or soya meal,” she said.

Lands ministry permanent secretary John Bhasera explains more about the program. 

“Pfumvudza is simply conservation agriculture. This is basically conservation which has been nationalized. It has minimum soil disturbance as well as mulching creating a blanket of cover so that you can conserve moisture. Crop rotation as well, we have three farming sectors—one for [a certain type of] cereal, another for [a different] cereal and the last for other crops,” he said.

Zimbabwe has been having farming schemes for the past decades but still, farmers are producing grain not enough to feed the nation. 

There is a need for new tactics. 

“We now have a new extension approach which is called Train, Track and Monitor (TTM). We have sourced motorcycles for our agriculture extension workers across the country so that they are able to practice the TTM approach. We started with training. We trained the Agritex officers for nearly a month. Now the extension officers are training farmers,” Bhasera said

Olga Nhari, Women in Agriculture Union chairperson speaks glowingly about the program. 

“Of the three plots one produces yield sufficient for family and the other two plots for national storage,” she said.

Nhari said Pfumvudza helps rural women, especially, to fight against hunger and to improve livelihoods. 

Zimbabwe Farmers Union executive director Paul Zakariya said there was a need to reverse the current state of affairs, where Zimbabwe has remained a net importer of staple cereals.

“It is not desirable that a country that has excellent agricultural lands and enjoys excellent climatic conditions, should import all its food,” he said.

In the past, farming schemes have been marred by corruption in the distribution of inputs as well as loan allocations. Some experts fear that the culture might continue under the Pfumvudza program.

“To say it is an opportunity to loot funds needs intelligence on whether the program will have a budget allocation and the actual implementation of the project in terms of funds or inputs allocation,” Harare based economist Victor Bhoroma told Ubuntu Times.

“However, almost all the country’s agricultural subsidy programs have flopped because of politicization of inputs distribution, corruption, inefficient funding or repayment models and lack of private capital participation which is tied to complicated land tenure policies,”

He said most of these agriculture programs are more political than economic of which in politics, the end justifies the means, hence, the government can pursue an economically costly program because it serves political interests.

Another economist Vince Musewe said Zimbabwe has invested in previous farming schemes but the country still imports grain.

“We have invested billions (of dollars) in Command Agriculture and we still have to import. We, however, need a new mindset that farming is a business and not a hobby where farmers expect to get free inputs,” said Musewe adding that a strong private sector drive in agriculture is important.

Zakariya said there is a need to put in place measures to curb abuse of inputs under such schemes. 

“Without effective and efficient systems, the world over, abuse can be rampant,” he said.

From Pfumvudza, the government is expecting about 1.8 million tonnes of grain, which is almost 90 percent of the national food requirements.

During the 2020/21 season, the LFSP aims to incorporate agroecology aspects as subsistence farmers like Mwastuku realize the fruits of their sweat. 

It is hoped that agroecology will better climate-proof smallholder agriculture production and will ensure nutrition for 50,000 households. 

Poor Infrastructures, Rapid Urban Sprawl Increase Flood Risk In Tanzania’s Largest City

Dar es Salaam, Tanzania — The breath-taking moment showing a family taking refuge on a rooftop as floodwater rapidly rushing into a submerging home at a low-lying Msasani neighborhood in Dar es Salaam—destroying furniture, carrying away cooking utensils, tells a grim story.

As heavy rains drizzled in Tanzania’s largest city last week, it triggered floods that engulfed homes, destroyed assets and infrastructures.

“I have lost everything,” said Jumbe Marijani, a resident of Msasani.

According to him, the entire neighborhood was entangled by the floods, making it hard to salvage personal belongings.

The 51-year-old father of six, who lives at the Kinondoni is among many residents who have been rendered homeless due to flooding.

“I have never seen such rains, it was horribly heavy,” said Marijani, whose family is squatting in a make-shift shack while waiting for the water to recede.

“I have incurred huge loss it will take time to recover,” said Marijani.

Africa’s Fastest Growing City

As one of Africa’s fastest-growing cities with nearly 70 percent of its six million inhabitants living in informal settlements, Dar es Salaam is highly vulnerable to flooding which often destroys infrastructures while causing water-borne diarrhea diseases.

Heavy rains twice a year, often cause floods that force thousands of the city’s residents from their homes and cause untold damage to the infrastructures.

In the Central Business District (CBD) and the Kariakoo business hub, the dilapidated sewage network often becomes overwhelmed during the rainy season—forcing effluents to overflow, exposing people to health hazards.

As authorities grapple with the impacts of climate change, local residents are bearing the heaviest burden due to logistical and infrastructural challenges.

Wastewater Dumping

For Ladislaus Mirindo, a gush of wastewater perpetually flowing from a broken sewer presents a serious health challenge to his family.

“I am quite worried for my children. They don’t have enough space to play, they oftentimes step on this dirty water,” he said.

The father of five, who lives in the Magomeni area, routinely dump the seeping sludge from his toilet in the nearby Msimbazi river.

“We do it at night to avoid being caught,” said 46-year-old Mirindo.

Most people in this squalid slum lack access to better sanitation, officials said.

“It cannot afford to hire a cesspit tanker. It costs around Tanzanian shillings 80,000(US$36) just for a single trip,” said Mirindo who works as a mason.

Rapid Urban Sprawl

As more than half of the world’s population is estimated to be living in cities, according to the United Nation projections, the share is likely to increase to 66 percent by 2050, with about 90 percent of the increase taking place in urban areas in Africa and Asia.

While rapid urbanization creates wealth and reduces poverty, analysts say it creates chaos in cities like Dar es Salaam which is vulnerable to flooding.

The smoke-belching city, which generates about 40 percent of Tanzania’s GDP and is poised to become a megacity by 2040 is exposed to many climate change risks notably flooding, sea-level rise, coastal erosion, all of which threaten infrastructure assets worth $5.3 billion, according to the United Nations.

As the number of people living in slums rises, Dar es Salaam epitomizes the growing challenge of dealing with urbanization, natural disasters, and poverty, according to urban planning experts at ICLEI, a network of more than a thousand cities working on sustainable development and resilience issues.

Vulnerability To Disasters

As authorities are grappling to resolve the city’s biggest environmental challenge: flooding, Dar’s low-lying geographical location increases its vulnerability to weather-related disasters.

According to Shahidi wa Maji, a local charity working to promote sustainable water resources, about a quarter-million people in the sprawling Msimbazi valley face serious health risks linked to the river’s “toxic industrial effluent, human sewage, chemicals and abattoir waste.

Strategic Plans

To cope with rapid urban sprawl, city authorities have redrawn a master plan for Dar es Salaam, with the aim to create a Metropolitan Development Authority that would be responsible for planning and infrastructure development including transportation and utilities.

Abubakar Kunenge, the Regional Commissioner for Dar es Salaam said government is working to identify flood-prone areas and draw up preparedness plans and strategic actions, such as installing early warning systems, to improve the people’s ability to respond to disasters and help them recover quickly.

“Our city has lately undergone a huge spatial growth, which cannot cope with the available facilities,” he told Ubuntu Times.

According to him, plans are afoot to mainstream climate change adaptation into existing urban development policies such as building stronger storm-water drainage systems in areas hard-hit by flood as well as relocating afflicted communities from flood risk areas.

Climate Proofing Interventions

However, Silvia Macchi, an associate professor of urban planning at Sapienza University in Italy who has worked on climate change adaptation in Dar es Salaam said enforcing land use policies in cities like this where informal settlements dominate is an uphill struggle.

“Rapid population growth and poor urban planning are the most significant challenges that Dar es Salaam faces.” She said adding “climate-proofing interventions should be carefully assessed against the risk of increasing unbalanced living conditions between different areas”

As part of its efforts to cushion vulnerable communities from disasters, the government relocated 654 families whose homes submerged in water during the 2011 floods.

Experts say the majority of city dwellers who live in flood-prone areas have no choice because they’re poor, even if they know their lives and property are at risk.

Most slum dwellers consider the rainy season as a temporary thing, they are willing to live with the threat of floods, soon forgetting the misery they’ve been through.

Until today, however much of Tanzania’s urban areas have been what the developmental economist Bohela Lunogelo terms “dysfunctional” characterized by poor infrastructures, lack of formal jobs, and haphazardly built slums.

Weak Regulations

Lack of planning, weak regulations, and the difficulty of obtaining title deeds for land lead cities to grow out rather than up, making commuting longer and costly.

In Dar es Salaam, about three-quarters of inhabitants live in informal settlements like Tandale, a vast, labyrinthine neighborhood of flimsily built concrete houses, where children play hide-and-seek near open sewers and flooding nearly every rainy season leads to outbreaks of diarrhea and cholera.

“My son nearly died from cholera last year, I don’t want to remember the ordeal I was through,” said Mirindo.

Could tree regeneration hold out hope for Africa’s vulnerable smallholder farmers?

Homa Bay, Kenya MARCH 4, 2020 — With more than half of the estimated 2.2 billion people to be added to the global population by 2050 expected to be from the African continent, according to the UN report on global population, this rapid growth and its development policies, especially in Sub-Saharan Africa will inhibit efforts to alleviate poverty, ensuring food security, preserving the environment, and improving Africans’ well-being, increasing vulnerability to climate change impacts and undermine sustainable development efforts on the continent.

Staring at a crisis in which some 256 million people are facing hunger, and where much of its current discourse on food security is focused on increasing and expanding agricultural production, the African continent’s expansion in agricultural production is speculated to be at the expense of natural resources.

As one of the solutions, an ambitious program dubbed Regreening Africa, a multi-country project funded by the European Union is seeking to scale up evergreen agriculture targeting an estimated 500,000 farm households over an area of one million hectares by 2022.

The eight beneficiary countries; Kenya, Somalia, Ethiopia, and Rwanda in East Africa and West Africa’s Niger, Mali, Ghana, and Senegal are at the forefront in restoring already degraded land to more productive use.

The project builds on the considerable experience in land restoration consortium partners which are World Agroforestry Centre as project lead, World Vision, Catholic Relief Services (CRS), CARE, Oxfam, and Sahel Eco.

“We are blending research with development and identify practices that are suitable for the different kinds of farms that we are working across the eight countries in East Africa and West Africa’s Sahel region. Working with research and development partners together helps us to be able to make decisions that are informed by scientific evidence,” Susan Chomba, Regreening Africa Project Manager told Ubuntu Times in an interview.

The project encourages the use of Farmer Managed Natural Regeneration (FMNR), a quick, affordable and easy-to-replicate way of restoring and improving agricultural, forested and pasture lands by promoting systematic regrowth of existing trees or from naturally occurring tree seeds. It can be used wherever there are living tree stumps with the ability to coppice (re-sprout) or seeds in the soil that will germinate.

Maxwell Ochoo, 32-year old father of four, quit his job as a community health mobilizer to engage in farming, a risky venture amidst degraded land in Lambwe, Kenya’s lakeside region.

“I worked as a community health mobilizer but when my contract ended, I resorted to try [my] luck in farming. It was a challenging undertaking with degraded land where none believed it would one day turn green,” says Ochoo.

After successfully practicing FMNR on his farm, Ochoo is currently a proud farmer as he is able to take his children to school, thanks to reliable income from his pawpaw fruits and a fish pond he established on his farm.

To minimize food cost for fish, I utilize calliandra — a small tropical legume tree he planted on his land, whose dry leaves are consumed by fish.

Farmers increase food security by retaining trees on agricultural land, by encouraging natural regeneration and by planting trees and other forest plants. For most of the year, herders in arid and semi-arid lands depend on trees as a source of fodder for their livestock.

Nancy Kemboi, a smallholder farmer in Baringo, a region characterized by constant drought also benefited on this simple innovative technique of protecting wildlings and pruning stumps that coppice so they rapidly regrow into trees.

Together with her husband, Nancy, through a capacity building on the FMNR skills offered by World Vision Kenya, she started regenerating indigenous trees such as acacia and re-growing pasture in the same field to cushion her livestock during extreme drought periods.

Africa’s indigenous trees coppice when cut, their stumps looking like weeds, but when farmers select the tallest and straight stems and cull the rest, trees rapidly grow.

“At first, the practice seemed [like] it would take long, but with patience and continuous pruning of the trees, benefits started to trickle. My children could not spend time having to fetch fuel wood mile away. I started getting fuel from tree branches, a product of pruning of growing sprouts,” Nancy told an interview at her farm.

Nancy’s children field soon started to contrast with the bare bleak ones of her neighbors. Her livestock started to thrive, with milk production increasing due to the availability of quality pasture.

“Before practicing FMNR, I used to get merely five-liter of milk a day from my cows, selling it to middlemen who used to buy at low prices,” says Nancy, adding that since her milk production increased, she now sells her milk to a nearby dairy facility.

Lilian Dodzo, World Vision Kenya Country Director says the decision to train and capacity-build farmers with simple skills on how to mitigate against the changing climate is such a big phenomenon in the current environment.

“It is important to build skills in our communities to find very simple and low-cost ways in which we can mitigate against climate change to be able to build the resilience of our communities,” Dodzo told in an interview.

She adds, “Our greatest interest in these activities is to see what it contributes to the child well-being. With access to pasture and more milk to sell, the income goes all the way to helping pay for children school fees, buy food and develop gardens where women can grow drought-resistant crops.”

According to Clare Rogers, World Vision Australia Chief Executive Officer, Nancy’s courageous move has not only changed her family but the community and farms around her area, with her neighbors starting to adopt the same approach after losing livestock to drought being an inspiration for the future.

“Nancy and her husband had the courage to try something new. They began to make the change happen here, and now her having to walk miles away to collect firewood solved. The changed landscape, availability of firewood and pasture means her kids can go to school,” she said.

“Women can change the world. This was not an easy journey but the fruit of the work after they did this was so obvious that it became very hard for people to deny,” Clare told a group of local farmers who had come to see the success in Nancy’s farm model.
