‘Vibrant’ cross-border trade in mopane worms from Botswana to South Africa

Published

BY SHERE BEGA

James Sekonya has spent more than six years studying mopane worms but he has still never tasted the edible caterpillars.

Sekonya, of the University of Cape Town’s department of environmental and geographical sciences, is the author of a new study that examines the “lucrative” cross-border trade in mopane worms, the caterpillar phase of the Imbrasia belina moth.

Historically, mopane worms have been harvested and consumed at the household level, with surplus used in barter trade to meet other household needs or to be shared with family, according to his thesis.

“Increasingly, mopane worms are gaining popularity among consumers in large cities and outside their natural range. An increasing rural-to-urban migration has driven the growing popularity as urban consumers reconnect with their rural lives.”

Vibrant trade

Estimates show that the mopane worm trade generates between $39-million and $100-million a year, “depending on the quality of the outbreak and prevailing weather conditions”.

In South Africa, this market is concentrated in peri-urban areas and is supplied by imports from Botswana and Zimbabwe, with most of this value accruing to traders rather than harvesters, the study notes.

Harvesting and related processing occur in Botswana, while bulk trading and vending are more concentrated in the South African markets.

Two factors are influential. “First, market prices have been shown to increase exponentially in times of shortage from June to November, long after harvesters had sold off their stock at lower prices. Second, traders increase profits through exporting to markets in South Africa where demand far exceeds supply from local harvest.”

Cumbersome’ regulations

Despite the numerous benefits of the trade, regulation is often “cumbersome, confusing, and debilitating” for impoverished individuals who wish to enter it, he said.

“This cross-border trade is regulated through legal, informal, and traditional rules, norms, and practices. Harvesters, exporters and traders have to navigate the constraints that result from the regulatory tools and take advantage of the gaps in the regulatory systems.”

Some resorted to varying levels of informality in which people complied with the regulations only where no alternatives existed, or they were guaranteed to gain more benefits.

“Nonetheless, influential, powerful, and wealthier actors were less constrained by the regulatory duplications and overlaps across the trade between Botswana and South Africa.”

Environmental change

During his master’s, Sekonya studied the effect of environmental change on mopane worm livelihoods in Limpopo. He found that expanding villages, the use of the mopane tree for fuel wood and material for fencing, among others, is shrinking the habitat of mopane worms.

“As a result, people who rely on harvesting in the local ‘forests’ are having less to harvest and the drought at the time worsened the situation,” he said. “The knock-on effects of that is when we went into the markets, we found that there was actually a lot of stock coming from outside of the country as a result of the decline in that region.”

He decided to dig deeper into the governance angle, “which I expected to be more prominent given the international borders that actors must cross to facilitate the trade”.

Sekonya found that although the importation of mopane worms caused prices to climb in South Africa, there was a strong preference for the stock coming from Botswana “because it’s been processed differently” — it is boiled in salt water after harvesting.

“The mopane worms from Botswana are bigger, purely based on the time at which people harvest. There’s still an understanding that one doesn’t just harvest when they see a caterpillar on a tree.

“They wait for them to reach a particular size and only harvest at that time. So, they’re much bigger and they have reached maturity, so to speak. The guts … have a lot less leaf matter, it’s got a lot of fat, and tastes good, so they say.”

Alternative protein

Globally, there is a growing interest in farming edible insects because they offer alternative protein at much less carbon and water footprint compared with meat. But commercialisation of these resources has a potential to spill over to the wild populations in contexts where commercial farming is not feasible.

“If the demand keeps increasing, obviously the supply will have to follow the trend,” said Sekonya. “I doubt that the wild populations in South Africa will be able to keep up.

“If we keep importing, especially from Botswana, we should be fine, but if mopane worms continue to be as popular as they are, and match the increasing popularity of edible insects in other countries across the world, there will be a need to start farming mopane worms as food and as feed. To protect the wild populations, the need for farming is becoming more obvious.”

He added that in South Africa mopane worms are not a high value species. “It doesn’t enjoy any protection and any dedicated regulations that deal with its harvesting, which is the opposite to what is happening in Botswana …

“There is plenty South Africa can do to emulate what is happening in Zimbabwe and Botswana to tap into the potential value of mopane worms to really unlock it to secure people’s livelihoods.”

Among the study’s recommendations is that Botswana and South Africa collaborate on developing a regulatory framework that promotes “seamless” cross-border movement while ensuring a greater pro-poor focus.

“This envisaged collaboration could help to empower impoverished harvesters and traders … and promote sustainable harvesting practices.”

Cultural identity

The study underscores the need to streamline statutory, customary and informal governance approaches particularly “as the three systems are not separate”, and to pursue an “unambiguous, pro-poor agenda” focused on safeguarding informal, resource-based livelihoods and the sustainable use of mopane worms.

Although commercialisation attracts prospective actors for economic reasons, mopane worms remain an inherent part of local diets, cultural identity, customary practices and livelihoods in harvester communities, according to the report.

These values must be considered when policy frameworks aimed at promoting resource commercialisation are designed and implemented.

“Had it not been through indigenous knowledge of mopane worms as a food source, it would just be a pest,” Sekonya said.

“It’s because of that culture, that knowledge of mopane worms as a very nutritious food source that it has now become a commercial product. The preservation of cultural practices and indigenous knowledge is one thing that must not be overlooked.

“There are the livelihoods of people who rely on mopane worms, who are not commercially driven, who are not business people, who are just people in communities who harvest this from communal forests to earn a living because there are very limited economic opportunities in their villages.

Should mopane worms blow up into this very lucrative product, which I think it will, protecting players on the other end of the scale will be very important.- Mail&Guardian

Zimbabwe makes gains against TB

Published

on

BY WANDILE TSHUMA

The World Health Organization (WHO) data show that Zimbabwe continues to make measurable gains in its fight against tuberculosis (TB).

According to the Global Tuberculosis Report 2025, Zimbabwe’s estimated TB incidence has declined to 203 per 100,000 population, representing a 3.8 % reduction from 2023. The report states that “TB incidence in Zimbabwe has fallen to 203 per 100 000, a 3.8 % reduction from 2023.” 

On treatment outcomes, the country’s overall success rate for all forms of TB has improved to 91 %, up from 89 % in 2023. The report quotes: “Treatment success for all forms of TB has improved to 91 %, up from 89 % in 2023.” 

For drug-resistant TB (DR-TB), progress has also been recorded: treatment success rose from 64 % for the 2021 cohort to 68 % for the 2022 cohort. As the report notes: “treatment success for drug-resistant TB increased from 64 % for the 2021 cohort to 68 % for the 2022 cohort.”

In the critical sphere of TB‐HIV co-infection, Zimbabwe saw a drop in the co‐infection rate to 49 %, down from 51 %. The report states: “TB/HIV co-infection rates have fallen to 49 %, down from 51 %.” 

Zooming out, the 2025 global report shows that across the world TB is falling again, although not yet at the pace required to meet targets. Globally, incidence declined by almost 2 % between 2023 and 2024, and deaths fell around 3 %. 

However, the report warns that progress is fragile. Funding shortfalls, health-system disruptions (especially during the COVID-19 era), and the ongoing challenge of drug-resistant TB threaten to erode gains. The WHO page reminds that the 2025 edition “provides a comprehensive … assessment of the TB epidemic … at global, regional and country levels.”

For example, although more people are being diagnosed and treated than in previous years, not enough are being reached with preventive interventions, and many countries are still far from the targets set under the End TB Strategy.

Zimbabwe pushes youth-centred, rights-based, and community-driven reforms ahead of CITES CoP20

Published

on

BY NOKUTHABA DLAMINI 

As the world prepares for the 20th Conference of the Parties (CoP20) to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), Zimbabwe has outlined a bold and comprehensive policy agenda that shifts global discussions beyond ivory and toward broader issues of sustainable use, human rights, and community empowerment.

In an exclusive interview with VicFallsLive, Dr. Agrippa Sora, board chairman of the Zimbabwe Parks and Wildlife Management Authority (ZimParks), said the country’s proposals are anchored on a simple but transformative message: wildlife conservation must deliver real benefits to the people living with wildlife.

Key proposals Zimbabwe taking to CITES CoP20

1. Commercial trade in elephant leather products

Zimbabwe is pushing for approval to engage in regulated commercial trade in elephant leather products. Authorities argue that this form of value addition can bring economic gains to local communities, promote sustainable use, and reduce reliance on donor funding.

2. A formal voice for communities within CITES

Zimbabwe is advocating for the establishment of an Advisory Body or Community Forum within CITES, ensuring that the voices of rural people—who coexist with wildlife—formally shape decisions on international trade, conservation restrictions, and benefit-sharing.

This push echoes one of the founding principles of CITES, which acknowledges that “peoples and States are and should be the best protectors of their own wild fauna and flora.”

3. Recognition of human rights within conservation governance

Zimbabwe’s delegation wants CoP20 to acknowledge the human rights dimensions of conservation—particularly:

  • The right to safety for communities facing human–wildlife conflict
  • The right to food security
  • The right to benefit from natural resources within their landscapes

For Zimbabwe, these rights are inseparable from wildlife management.

Moving beyond ivory: A broader view of sustainable use

Dr. Sora emphasized that Zimbabwe does not want the CoP20 debate to be reduced to ivory.

Zimbabwe argues that without these broader interventions, the conservation model remains unbalanced—protecting wildlife while leaving the people who live among it trapped in poverty

Youth at the centre of the conservation agenda

One of the strongest themes in Zimbabwe’s CoP20 position is youth empowerment, an area Dr. Sora said is now central to national conservation policy.

“Zimbabwe is supporting the Youth Ethnic Conservation Agenda, and we want to continue empowering young people,” Dr. Sora said.

“These are young people who travel long distances between villages and shopping centres, often unaware of wildlife incidents happening around them.”

He revealed that Zimbabwe has approved the establishment of a national chapter of the CITES Rural Youth Network, a platform designed to give young rural citizens a voice in global conservation decision-making.

Dr. Sora said young people—often traveling long distances between villages and service centres—are the first responders to wildlife encounters, yet are rarely included in policy processes.

“Their inclusion is critical for awareness, safety, and community resilience,” he said.

A rights-based approach linked to national priorities

Dr. Sora linked Zimbabwe’s CITES proposals to the country’s National Development Strategy (NDS2), which prioritises poverty eradication.

“We want to ensure that communities living within wildlife landscapes receive meaningful support and benefits from the natural resources around them,” he said.

This includes promoting value addition—for example, crafting products from elephant leather—and enabling community enterprises tied to legal wildlife products.

“We are promoting opportunities for value addition so that communities can benefit economically from the wildlife with which they coexist.”

He added that the board is committed to transitioning youth from vulnerability to empowerment, ensuring access to education, business opportunities, and long-term livelihoods.

Unlocking finance through sustainable use

Zimbabwe also plans to push for financial mechanisms—particularly the sustainable use of existing wildlife stockpiles—to support community development.

“Our aim is to secure mechanisms that allow us to reinvest in these communities, strengthening their resilience and ensuring they thrive alongside wildlife.”

Zimbabwe argues that restrictive global trade rules deprive communities of funding that could improve safety, reduce human–wildlife conflict, and support conservation programs.

Zimbabwe’s position rooted in CITES founding principles

Zimbabwe’s proposals, Dr. Sora said, are consistent with the spirit of CITES itself.

The convention’s preamble affirms:

Wild fauna and flora are an irreplaceable part of the earth’s natural systems… Peoples and States are and should be the best protectors of their own wild fauna and flora… International cooperation is essential to prevent over-exploitation…

Zimbabwe believes that empowering communities, recognizing human rights, and enabling sustainable use are simply modern applications of these foundational principles.

Drought has brought trucks of shame to Lupane

Published

on

BY NOKUTHABA DLAMINI

In rural Lubimbi and Gwayi, Lupane district, the drought has done more than dry up rivers; it is straining communities.

Advertisement

Year after year, the rains fail, fields are left cracked and hunger tightens its grip. Now, girls as young as 14 are being drawn into sex work—sometimes with their parents’ knowledge—just to put food on the table.

At Gwayi growth point, where haulage trucks park overnight along the Victoria Falls–Bulawayo highway, the trade is an open secret.

Harvest of Pain

“We see a lot of trucks coming here to park,” says Coster Ncube, a Gwayi villager. “Parents end up allowing their daughters to roam around at night for sex work because there’s no food at home. The fathers are unemployed and poverty is crushing us.”

Ncube’s voice carries both anger and grief. His 13-year-old niece, who was in Grade 7, recently fell pregnant after being sexually exploited by a married man who has since vanished.

“She’s in hospital now, waiting to give birth,” he told NewsHub on 26 September. “It’s heartbreaking. These are children who should be in school, not out here dying of diseases.”

He adds that the girls often come from as far as Jotsholo, Mabale, Cross Dete, Lupote and Lupane Centre—hundreds of kilometres away—drawn by the trucks and the chance to earn a few dollars through commercial sex.

“They’re between 14 and 21,” he says. “All they want is survival.”

For Selina Mthupha, a 47-year-old widow and small-scale farmer in Lubimbi, climate change has turned her once productive fields into dust.

“We used to have maize and groundnuts stacked in our granaries,” she says. “Now, even the millet dies before it tassels. The borehole water is salty, and the riverbeds are dry.”

She says she struggles to feed her two teenage daughters. “When I hear that girls their age are doing sex work for two dollars, I don’t judge. I cry. Because hunger can make you do things you never thought possible.”

Selina says she once dreamed of sending her children to college. “Now I just dream of rain.”

The desperation in Lupane mirrors findings from national research.

A 2025 study titled “Climate Change and the Feminisation of Poverty in Africa” established that climate change in rural Zimbabwe is deepening food insecurity and forcing women and girls into survival strategies that expose them to exploitation.

The study noted that failed harvests and long dry spells have left women with fewer economic options and greater vulnerability to abuse and transactional sex.

Another report published in 2021, “Challenges Faced by Rural People in Mitigating the Effects of Climate Change in the Mazungunye Community, Masvingo Province”, found that communities were already suffering the direct impacts of climate change: failed crops, loss of livestock, and worsening poverty.

It warned that most rural families lack access to climate-adaptive resources, leaving them trapped in a cycle of vulnerability.

For Ruth Bikwa, director of Hopeville, an organisation which works in child protection in Hwange’s Matabeleland North province, the crisis reflects a dangerous intersection of climate change, poverty, and neglect.

“When harvests fail and there’s nothing to eat, girls start finding other means to survive,” she explains.

“It’s not about choice, it’s about hunger. They trade sex for one or two dollars, just enough to buy mealie-meal or soap. And once they start, they face abuse, disease, and stigma. It becomes a trap.”

Bikwa says when droughts and economic shocks worsen, so does child exploitation. “It follows the poverty line. The harsher the climate, the more vulnerable the children become.”

“We Are Failing Our Children”

At Gwayi Centre, a resident, Shelter Vengesai Mpofu says drought has turned daily life into a survival theatre.

“Our boreholes run dry by midday,” she says. “We used to harvest from our fields, but now there’s nothing. The children see others making money from truck drivers and think that’s their only chance.”

She pauses, then continues: “We are failing our children — not because we want to, but because poverty leaves us helpless.”

At Gwayi Valley Primary School, teacher Mthulisi Ncube (name changed as teachers are not always allowed to speak directly with the press) says climate change is not only wiping out crops but also the classroom.

“We’ve lost many girls from the upper grades,” he says. “Some stop coming because they don’t have uniforms or sanitary pads. Others are lured by quick money. You can tell when hunger follows a child. They stop concentrating, then they disappear.”

He says teachers try to intervene, but most families are too poor to cope. “How do you tell a hungry child to stay in school when there’s no food at home? It’s better though now because the government at times provides hot meals in schools after realising this challenge.”

“It’s Laziness, Not Hunger”

Ward 24 councillor Senzeni Sibanda sees things differently.

“Our children don’t want to go to school or do physical work,” she says. “We have a vocational training centre and detergent-making lessons for just three dollars, but they refuse. They prefer quick money.”

Sibanda says her office has appealed for limits on overnight truck parking but was told the law allows drivers to rest anywhere along the road.

“The trucks bring prostitution, yes, but our youths are also lazy. They don’t want to work.”

Advertisement

Her remarks, however, clash sharply with what parents and activists say: that climate-induced poverty, not laziness, is driving desperation.

Human rights advocates warn that without urgent action — food relief, youth empowerment programs, and climate adaptation projects — the situation will worsen.

“It’s easy to judge,” says Bikwa, “but when the earth no longer gives, people do what they must to survive.”

For many families, this is what climate change looks like—not just cracked soil and empty dams, but lost childhoods and futures fading in the dust.

A 2024 parliamentary meeting revealed a staggering statistic: 4 557 school girls dropped out of school due to pregnancy in 2023 alone.

The majority of these girls (3 942) were from rural schools, and most were in secondary school.

Then, minister of Primary and Secondary Education, Torerai Moyo, said the Education Management Information System (EMIS) tracked these annual figures, and that the government was introducing guidance, counselling in schools, and legal protections via the Education Amendment Act of 2020, allowing pregnant girls to take a two week maternity leave and return.

Recent statistics from the National AIDS Council (NAC) show that Matabeleland North Province has an adult HIV prevalence rate of about 14.4–14.5% among people aged 15 and above, significantly higher than the national average of around 11.7%.

This elevated rate is linked to factors such as increased sex work around mining sites and business centres, migration, spousal separation, and inconsistent condom use. NAC has specifically flagged Bubi District as one of the areas with high risk due to mining and business centre activity, as well as Lupane and Hwange.
