HARARE — From ancient fertilizer methods in Zimbabwe to new greenhouse technology in Somalia, farmers across the heavily agriculture-reliant African continent are looking to the past and future to respond to climate change.

Africa, with the world’s youngest population, faces the worst effects of a warming planet while contributing the least to the problem. Farmers are scrambling to make sure the booming population is fed.

With more than 60% of the world’s uncultivated land, Africa should be able to feed itself, some experts say. And yet three in four people across the continent cannot afford a healthy diet, according to a report last year by the African Union and United Nations agencies. Reasons include conflict and lack of investment.

In Zimbabwe, where the El Nino phenomenon has worsened a drought, small-scale farmer James Tshuma has lost hope of harvesting anything from his fields. It’s a familiar story in much of the country, where the government has declared a $2 billion state of emergency and millions of people face hunger.

But a patch of green vegetables is thriving in a small garden the 65-year-old Tshuma is keeping alive with homemade organic manure and fertilizer. Previously discarded items have again become priceless.

“This is how our fathers and forefathers used to feed the Earth and themselves before the introduction of chemicals and inorganic fertilizers,” Tshuma said.

He applies livestock droppings, grass, plant residue, remains of small animals, tree leaves and bark, food scraps and other biodegradable items like paper. Even the bones of animals that are dying in increasing numbers due to the drought are burned before being crushed into ash for their calcium.

Climate change is compounding much of sub-Saharan Africa’s longstanding problem of poor soil fertility, said Wonder Ngezimana, an associate professor of crop science at Zimbabwe’s Marondera University of Agricultural Sciences and Technology.

“The combination is forcing people to re-look at how things were done in the past like nutrient recycling, but also blending these with modern methods,” said Ngezimana, whose institution is researching the combination of traditional practices with new technologies.

Apart from being rich in nitrogen, organic fertilizers help increase the soil’s carbon and ability to retain moisture, Ngezimana said. “Even if a farmer puts synthetic fertilizer into the soil, they are likely to suffer the consequences of poor moisture as long as there is a drought,” he said.

Other moves to traditional practices are under way. Drought-resistant millets, sorghum and legumes, staples until the early 20th century when they were overtaken by exotic white corn, have been taking up more land space in recent years.

Leaves of drought-resistant plants that were once a regular dish before being cast off as weeds are returning to dinner tables. They even appear on elite supermarket shelves and are served at classy restaurants, as are millet and sorghum.

This could create markets for the crops even beyond drought years, Ngezimana said.

A greenhouse revolution in Somalia

In conflict-prone Somalia in East Africa, greenhouses are changing the way some people live, with shoppers filling up carts with locally produced vegetables and traditionally nomadic pastoralists under pressure to settle down and grow crops.

“They are organic, fresh and healthy,” shopper Sucdi Hassan said in the capital, Mogadishu. “Knowing that they come from our local farms makes us feel secure.”

Her new shopping experience is a sign of relative calm after three decades of conflict and the climate shocks of drought and flooding.

Urban customers are now assured of year-round supplies, with more than 250 greenhouses dotted across Mogadishu and its outskirts producing fruit and vegetables. It is a huge leap.

“In the past, even basic vegetables like cucumbers and tomatoes were imported, causing logistical problems and added expenses,” said Somalia’s minister of youth and sports, Mohamed Barre.

The greenhouses also create employment in a country where about 75% of the population is people under 30 years old, many of them jobless.

About 15 kilometers from the capital, Mohamed Mahdi, an agriculture graduate, inspected produce in a greenhouse where he works.

“Given the high unemployment rate, we are grateful for the chance to work in our chosen field of expertise,” the 25-year-old said.

Meanwhile, some pastoralist herders are being forced to change their traditional ways after watching livestock die by the thousands.

“Transitioning to greenhouse farming provides pastoralists with a more resilient and sustainable livelihood option,” said Mohamed Okash, director of the Institute of Climate and Environment at SIMAD University in Mogadishu.

He called for larger investments in smart farming to combat food insecurity.

A more resilient bean in Kenya

In Kenya, a new climate-smart bean variety is bringing hope to farmers in a region that had recorded reduced rainfall in six consecutive rainy seasons.

The variety, called “Nyota” or “star” in Swahili, is the result of a collaboration between scientists from the Kenya Agricultural and Livestock Research Organization, the Alliance of Bioversity International and research organization International Center for Tropical Agriculture.

The new bean variety is tailored for Kenya’s diverse climatic conditions. One focus is to make sure drought doesn’t kill them off before they have time to flourish.

The bean variety flowers and matures so quickly that it is ready for harvesting by the time rains disappear, said David Karanja, a bean breeder and national coordinator for grains and legumes at KALRO.

Hopes are that these varieties could bolster national bean production. The annual production of 600,000 metric tons falls short of meeting annual demand of 755,000 metric tons, Karanja said.

Farmer Benson Gitonga said his yield and profits are increasing because of the new bean variety. He harvests between nine and 12 bags from an acre of land, up from the previous five to seven bags.

One side benefit of the variety is a breath of fresh air.

“Customers particularly appreciate its qualities, as it boasts low flatulence levels, making it an appealing choice,” Gitonga said.

LAGOS, Nigeria — When a small number of cases of locally transmitted malaria were found in the United States last year, it was a reminder that climate change is reviving or migrating the threat of some diseases. But across the African continent malaria has never left, killing or sickening millions of people.

Take Funmilayo Kotun, a 66-year-old resident of Makoko, an informal neighborhood in Nigeria’s Lagos city. Its ponds of dirty water provide favorable breeding conditions for malaria-spreading mosquitoes. Kotun can’t afford insecticide-treated bed nets that cost between $7 and $21 each, much less antimalarial medications or treatment.

For World Malaria Day on Thursday, here is what you need to know about the situation in Africa:

Malaria is still widespread

The malaria parasite mostly spreads to people via infected mosquitoes and can cause symptoms including fever, headaches and chills. It mostly affects children under 5 and pregnant women.

Vaccine efforts are still in early stages: Cameroon this year became the first country to routinely give children a new malaria vaccine, which is only about 30% effective and doesn’t stop transmission. A second vaccine was recently approved. On Thursday, WHO announced that three African countries — Benin, Liberia and Sierra Leone — were rolling out vaccine programs for millions of children.

Cases of resistance to antimalarial drugs and insecticides are increasing, while funding by governments and donors for innovation is slowing.

Living conditions play a role, with crowded neighborhoods, stagnant water, poor sanitation and lack of access to treatment and prevention materials all issues in many areas. And an invasive species of mosquito previously seen mostly in India and the Persian Gulf is a new concern.

A growing problem

Globally, malaria cases are on the rise. Infections increased from 233 million in 2019 to 249 million in 85 countries in 2022. Malaria deaths rose from 576,000 in 2019 to 608,000 in 2022, according to the World Health Organization.

Of the 12 countries that carry about 70% of the global burden of malaria, 11 are in Africa and the other is India. Children under 5 constituted 80% of the 580,000 malaria deaths recorded in Africa in 2022.

COVID-19 hurt progress

The fight against malaria saw some progress in areas such as rapid diagnostic tests, vaccines and new bed nets meant to counter insecticide resistance, but the COVID-19 pandemic and a shift in focus and funding set back efforts.

A study published in Tropical Medicine and Infectious Disease last year said COVID-19-induced lockdowns led to disruptions at 30% of rural community health service points across Africa. Malaria cases started spiking again, breaking a downward trend between 2000 and 2019.

That downward trend could soon return, according to the WHO.

A warming world and new frontiers

Africa is “at the sharp end of climate change,” and the increasing frequency of extreme weather events causes havoc in efforts to combat malaria in low- and middle-income regions, Peter Sands, the executive director of the Global Fund to Fight AIDS, Tuberculosis and Malaria, warned in December.

In 2023, the WHO’s World Malaria Report included a chapter on the link between malaria and climate change for the first time, highlighting its significance as a potential risk multiplier. Scientists worry that people living in areas once inhospitable to mosquitoes, including the slopes of Mount Kilimanjaro and the mountains of eastern Ethiopia, could be exposed.

In Zimbabwe, which has recorded some of its hottest days in decades, malaria transmission periods have extended in some districts, “and this shift has been attributed to climate change,” said Dr. Precious Andifasi, a WHO technical officer for malaria in Zimbabwe.

SYDNEY — The Asian Development Bank holds its annual meeting in Tbilisi, Georgia, next week, with discussions on climate change and the world’s aging population high on the agenda.

The four-day summit, starting Thursday, marks the first time that the ADB’s 68 members have gathered for a meeting in Georgia, which joined the multilateral development bank in 2007.

“Georgia sits at the crossroads of Europe and Asia,” said Shalini Mittal, a principal economist for Asia at the Economist Intelligence Unit.

“This meeting signifies ADB’s agenda of bridges to the future where technology and expertise from the West can be used to enhance structural reforms in Asia,” Mittal told VOA.

Alongside numerous panel discussions and a keynote speech from ADB President Masatsugu Asakawa, finance ministers from Association of Southeast Asian Nations member countries Japan, China and South Korea will also meet on the sidelines.

“Given the geopolitical uncertainty with the Ukraine-Russia war and tensions in Asia with China’s problematic relations with its neighbors, I think the meeting is taking place at a crucial time,” said Jason Chung, a senior adviser with the Project on Prosperity and Development at Washington’s Center for Strategic and International Studies.

“It provides an additional path to have meaningful discussions on global economic issues,” Chung told VOA.

Climate change stressed

The issue of climate change is set to headline proceedings at the conference, with the ADB now marketing itself as the climate bank for the Asia-Pacific region.

The bank pledged a record $9.8 billion of climate finance in 2023, supporting developing countries to cut greenhouse emissions and adapt to extreme conditions as global warming continues.

“Storm surges, sea level rise, heat waves, droughts, and floods — all our countries suffer from all of the imaginable impacts of climate change,” said Warren Evans, who, as senior special adviser on climate change in the ADB president’s office, acts as the institution’s climate envoy.

The bank says that the Asia-Pacific region was hit by over 200 disasters last year alone, with many of them weather related, a problem that shows no sign of letting up.

“Right now, there’s a heatwave in Bangladesh that is causing severe impacts. Schools are closed, they’re seeing a drop in agricultural productivity, hospitals are getting overloaded with people with heatstroke,” Evans told VOA.

“Mortality rates are going up and, of course, women and children are the most vulnerable to those impacts,” he said.

While much of the Asia-Pacific region is extremely vulnerable to climate change, it is also a huge driver of the phenomenon.

The region contributes more than half of global carbon dioxide emissions, with a heavy reliance on coal as a source of energy, according to the ADB.

To try to reach net zero targets, many Asia-Pacific nations require huge investment to convert to clean energy alternatives.

One way that the ADB is tackling this issue is through a program targeting coal-burning power plants, a major contributor to emissions.

“With private sector partners and sovereign funding, we’re refinancing coal-fired power plants in order to be able to close them down early,” Evans said. The ADB’s “energy transition mechanism” uses private and public capital to refinance investments in coal-fired power, allowing power purchase agreements to be shortened and plants to be closed as much as a decade earlier than planned. The financing is also used to fund clean energy projects to generate the power that would have come from the coal plant.

The project looks to replace these plants with clean energy alternatives, ensuring that power is generated more sustainably.

A coal-burning power plant in Indonesia’s West Java is set to become the first to be retired early under the initiative.

“The communities that are impacted will have support, allowing people to find new jobs or to get social welfare,” Evans said.

 

Aging population in Asia

During the Tbilisi summit, the ADB will also launch a major report on aging population, which also affects member countries’ economies.

According to the bank, 1 in 4 people in the Asia-Pacific region will be over 60 by 2050, close to 1.3 billion people.

“The speed of aging is very quick in Asia, because of the rapid progress in the social development that has taken place in the region,” said Aiko Kikkawa, a senior economist for the ADB’s Aging Well in Asia report.

Researchers have investigated the implications of this demographic transition, with Kikkawa finding that the Asia-Pacific region is currently “unprepared” for aging populations.

“Large numbers of older people do report a substantial disease burden, lack of access to decent jobs or essential services, such as health and long-term care, and even lack of access to pension coverage,” Kikkawa told VOA.

The ADB has pledged to help to improve the lives of older people across the Asia-Pacific region, by supporting the rollout of universal health coverage and providing infrastructure for ‘age-friendly cities’ that are more accessible for older people.

Poverty to be addressed

While much of the focus in Tbilisi will be on climate change and aging populations, the ADB’s core edict remains to eradicate extreme poverty in its many developing country members.

That task has become even more challenging in an environment of high inflation and growing government debt.

However, Chung, the former U.S. director of the ADB, told VOA he believes that this goal should be at the center of discussions in the Georgian capital.

“The ADB should focus on its core mission of alleviating poverty and creating paths for economic growth in the developing member countries.

“While climate risk is important, I think given the state of uncertainty, it is important to provide support to create economic conditions for growth,” he told VOA.

washington — About one-quarter of U.S. adults age 50 and older who are not yet retired say they expect to never retire, and 70% are concerned about prices rising faster than their income, an AARP survey finds.

About 1 in 4 have no retirement savings, according to research released Wednesday by the organization that shows how a graying America is worrying more and more about how to make ends meet even as economists and policymakers say the U.S. economy has all but achieved a soft landing after two years of record inflation.

Everyday expenses and housing costs, including rent and mortgage payments, are the biggest reasons why people are unable to save for retirement.

The data will matter this election year as Democratic President Joe Biden and Republican rival Donald Trump are trying to win support from older Americans, who traditionally turn out in high numbers, with their policy proposals.

Everyday expenses hamper saving

The AARP’s study, based on interviews completed with more than 8,000 people in coordination with the NORC Center for Public Affairs Research, finds that one-third of older adults with credit card debt carry a balance of more than $10,000 and 12% have a balance of $20,000 or more. Additionally, 37% are worried about meeting basic living costs such as food and housing.

“Far too many people lack access to retirement savings options and this, coupled with higher prices, is making it increasingly hard for people to choose when to retire,” said Indira Venkateswaran, AARP’s senior vice president of research. “Everyday expenses continue to be the top barrier to saving more for retirement, and some older Americans say that they never expect to retire.”

The share of people 50 and older who say they do not expect to retire has remained steady. It was 23% in January 2022 and 24% that July, according to the study, which is conducted twice a year.

“We are seeing an expansion of older workers staying in the workforce,” said David John, senior strategic policy advisor at the AARP Public Policy Institute. He said this is in part because older workers “don’t have sufficient retirement savings. It’s a problem and its likely to continue as we go forward.”

In the AARP survey, 33% of respondents 50 and older believe their finances will be better in a year.

Based on the 2022 congressional elections, census data released Tuesday shows that voters 65 and older made up 30.4% of all voters, while Gen Z and millennials accounted for 11.7%.

Biden has tried to court older voters by regularly promoting a $35 price cap on insulin for people on Medicare. He trumpets Medicare’s powers to negotiate directly with drugmakers on the cost of prescription medications.

Trump, in an interview with CNBC in March, indicated he would be open to cuts to Social Security and Medicare. The former president said “there is a lot you can do in terms of entitlements, in terms of cutting.”

Karoline Leavitt, press secretary for Trump’s campaign, said in a statement to The Associated Press on Tuesday that Trump “will continue to strongly protect Social Security and Medicare in his second term.”

Candidates court senior voters

A looming issue that will affect Americans’ ability to retire is the financial health of Social Security and Medicare.

The latest annual report from the program’s trustees says the financial safety nets for millions of older Americans will run short of money to pay full benefits within the next decade.

Medicare, the government-sponsored health insurance that covers 65 million older and disabled people, will be unable to pay full benefits for inpatient hospital visits and nursing home stays by 2031, the report forecast. And just two years later, Social Security will not have enough cash on hand to pay out full benefits to its 66 million retirees.

An AP-NORC poll from March 2023 found that most U.S. adults are opposed to proposals that would cut into Medicare or Social Security benefits, and a majority support raising taxes on the nation’s highest earners to keep Medicare running as is.

sydney — Analysis of more than 25,000 images from divers, tourism operators and recreational boats on Australia’s annual Great Reef Census is getting under way. Now in its fourth year, one of the world’s fastest-growing conservation projects is helping to gauge the health and degradation of the world’s largest coral system, which is suffering from another mass bleaching event.

The Great Reef Census collects a trove of images of what is arguably Australia’s greatest natural treasure.

Each picture can contain vital information about the health of the Great Barrier Reef. Together, the images create a vital evaluation of the state of the ecosystem.

The barrier reef stretches for 2,300 kilometers down Australia’s northeastern coast. It is under increasing threat from global warming, pollution and overfishing, as well as coral-eating crown of thorns starfish.

The surveillance project is urging so-called citizen scientists around the world to help in the analysis of the images. The survey also uses artificial intelligence to scan much of the data.

The public is being asked to analyze the images to see which reefs fared better than others and potentially identify so-called new “key source reefs,” which are those reefs that appear to have escaped the worst of the degradation.

Anyone can help in the effort, said Nicole Senn, impact and engagement lead at Citizens of the Reef, which coordinates the survey.

“Citizen scientists using our A.I assisted platform can actually provide data that is highly comparable in accuracy to a reef expert, and it takes as little as one minute to analyze an image, and the data you are generating helps to prioritize conservation efforts on the reef and identify key source reefs,” she said. “These are healthy reefs that are positioned in a way that they can help nearby reefs recover and this is just one of the many ways your analysis of these images can help.”

The Great Barrier Reef is suffering from another widespread bleaching event.

Scientists say that corals bleach, or turn white, when they are stressed by changes in water temperature, light, or nutrients. In response, the coral expels the symbiotic algae living in their tissues that give them their color and energy, exposing their white skeleton.

Not all bleaching incidents are due to warm water, but experts say the mass bleaching reported on the Great Barrier Reef is caused by a marine heatwave.

Experts say reefs around the world last year and early this year have been affected by high ocean surface temperatures.

Chris Lawson, a data scientist with the Great Reef Census’ Science Committee, told VOA that the situation appears to be dire.

“The latest mass bleaching event has been designated as the fourth global mass bleaching event,” he said. “So, it is not just in Australia, it has been observed globally and by all accounts is the worst one on record in terms of its extent and its severity of bleaching.”

Experts say reefs’ extreme susceptibility to warming sea temperatures makes them one of the world’s ecosystems that is most vulnerable to climate change.
