Naivasha, Kenya – For communities living around Naivasha, water is not an abstract resource. It sustains families, livestock, farms and schools.

That reality has taken on new significance after plans for a major Microsoft-G42 data centre in Olkaria, near Lake Naivasha, stalled in May 2026 over concerns about available power capacity.

Microsoft and United Arab Emirates-based artificial intelligence company G42 announced the project in 2024 as part of a $1bn digital investment package for Kenya. The proposed facility was to run on geothermal energy and eventually scale to as much as 1 gigawatt of capacity.

The uncertainty has also prompted questions about what another major industrial user could mean for water in a region where residents already report shortages.

Microsoft and G42 said the proposed data centre campus would run entirely on renewable geothermal energy and incorporate water conservation technology. The companies did not disclose a project-specific water consumption figure in their 2024 announcement.

Kenya Electricity Generating Company (KenGen) communications director Frank David Ochieng told Al Jazeera that the data centre remains at the design stage and that he could not comment further until the project is ready to proceed.

For residents like Musa Olorkedienye, who spoke to Al Jazeera, water scarcity is already a daily concern. He says communities around Olkaria have seen changes in access to water, including the loss of reliable piped supplies that residents previously received from KenGen.

“Currently, we are relying on water vendors to get water, our animals are walking for kilometres, and we fear things could get worse as demand for water rises,” Olorkedienye says.

Pastoralist Isaac Leshishi, who also spoke to Al Jazeera, says increasingly harsh weather is adding to the pressure.

Why Olkaria?

The choice of Olkaria was closely tied to energy. The area is home to Kenya’s major geothermal operations, making it an attractive location for a power-intensive facility.

KenGen operates the Olkaria geothermal complex, while Microsoft and G42 planned to power the proposed data centre entirely with geothermal energy.

A lake under pressure

Naivasha is a freshwater lake in Kenya’s Rift Valley whose catchment supports agriculture, tourism, livestock and domestic water use. Its basin also hosts geothermal development and other economic activity.

Grace Kimani, a patrol leader with Lake Naivasha and Oloiden, told Al Jazeera that the reservoir is under growing pressure from population growth, agriculture, water abstraction, climate variability, pollution and ecosystem degradation.

“The planned Microsoft-G42 data centre in Olkaria could bring jobs and investment, but its water demand raises concerns about adding pressure to already competing needs, particularly during dry periods,” she said.

Kimani said there is limited public information about the project’s expected water demand, source and cooling technology. She said transparency and an assessment of its cumulative impact on water resources would be important.

She also called for water-efficient or water-free cooling, water recycling and the use of treated wastewater, as well as sustainable abstraction limits and community involvement in monitoring.

Silas Wanjala of the Lake Naivasha Riparian Association, who spoke to Al Jazeera, said the region is heavily dependent on groundwater and that declining water flows are adding to the pressure.

“These industries, especially EcoCloud, which deal with data, will consume a lot of water at a time when rivers are drying, and demand for water is on the rise,” Wanjala said.

Olkaria EcoCloud Data Centre is a local partner in the G42-led development. In 2024, the Kenya News Agency reported that G42, Microsoft and EcoCloud signed a letter of intent for the wider data-centre initiative, with EcoCloud described as a local partner that had previously signed a memorandum of understanding with G42.

Wanjala points to past fluctuations in Lake Naivasha as a warning.

“This lake in 2010 nearly dried up due to over-abstraction, and this could be repeated due to high demand for water by these investors in Olkaria,” he says.

His concern comes against a wider backdrop of water scarcity in Kenya. The Food and Agriculture Organization (FAO) of the United Nations says Kenya has about 527 cubic metres (527,000 litres) of freshwater available per person, below the 1,000-cubic-metre threshold for water scarcity, and estimates availability could fall to about 475 cubic metres per person by 2030.

The figures do not show what effect the proposed data centre would have on Lake Naivasha. They provide context, however, for why the prospect of another major water user is drawing scrutiny in a region where demand is already high.

How much water would it use?

The amount of water the proposed Microsoft-G42 facility itself would require remains unclear.

The project announcement provides no projected consumption figure.

Existing industrial use offers some context.

A KenGen environmental and social impact assessment records that 195,165 cubic metres of water were abstracted from Lake Naivasha in July 2023 for domestic and commercial uses at Olkaria and for operations and domestic use at Eburru.

Of that total, 153,918 cubic metres were used for commercial operations at Olkaria. The assessment records the abstraction as within Water Resources Authority (WRA) permitted levels.

Those figures relate to existing KenGen operations, not the proposed data centre.

For farmer Eskimos Kobia, who spoke to Al Jazeera, the potential competition extends beyond households and livestock. He says farmers, pastoralists, schools and investors will all face greater pressure as demand increases.

Kimani said climate variability has also led to fluctuations in lake levels, with periods of flooding followed by prolonged dry conditions.

“Water quality is affected by agricultural run-off, untreated wastewater in some areas and invasive species,” she says.

Investment versus local concerns

Not everyone in Naivasha opposes the investment.

Absolom Mukhuusi of the Naivasha Professional Association, who spoke to Al Jazeera, says the technology sector could bring jobs, infrastructure and new businesses to the area. But he says economic benefits should not come at the expense of local communities.

“Even as we welcome the investors, our biggest fear is what happens to our water bodies and communities as water is diverted to Olkaria for the heavy users,” he says.

Could technology help?

Geologist Kenyatta Otieno, who spoke to Al Jazeera, sees another potential benefit.

He recalls the pressure large flower farms once placed on the lake’s ecosystem, saying many have since left or scaled back their operations.

Otieno says the proposed centre would have included a resource centre to monitor lake levels and weather patterns. Such monitoring, he says, could help identify the highest water level over time and guide riparian land zoning.

“The centre being built with water conservation in mind would be futuristic as Naivasha is generally a water-scarce area. It would be a model for future development,” Otieno said.

Kenya already has regulators responsible for managing competing demands. The WRA regulates water abstraction and issues water-use permits, while the National Environment Management Authority (NEMA) oversees environmental impact assessments under the country’s environmental regulatory framework.

Attempts by Al Jazeera to obtain comments from WRA and NEMA officials were unsuccessful. Efforts to reach Microsoft-G42 officials and Kenyan government officials for comment on the project’s status and water requirements were also unsuccessful.

For now, the project’s eventual scale, design and water requirements remain unclear, according to KenGen.

“We are now competing with the multibillion [-dollar] companies for water, and we fear that we shall be the losers in the long run,” Leshishi said.

China is set to launch its Chang’e-7 unmanned, robotic space mission, possibly as early as Monday morning, to look for ice water in the permanently shadowed craters of the moon’s south pole.

This marks China’s seventh and most ambitious moon mission so far. Here is what we know about it.

What do we know about Chang’e-7?

The Chang’e‑7 launch window runs from Monday, August 24 to Monday, August 31, according to launch observers. That means the mission could lift off on any day in that period.

The Chang’e-7 comprises an orbiter, a lander, a rover and a hopper.

• The orbiter is the main spacecraft which will remain in the moon’s orbit, mapping the surface and taking images while the mission is under way. It will also relay data and communications between the other Chang’e‑7 components and Earth.
• The lander is the vessel that will touch down on the lunar surface, loaded with the necessary scientific instruments for lunar exploration, near the edge of the Shackleton Crater, a 21km-wide (13-mile-wide) pit close to the moon’s south pole. Lunar missions before this have never come this close to the pole.
• The rover is a small robotic vehicle which can drive around the landing site and which carries equipment to analyse the local environment, including rocks and soil.
• The hopper is a small robotic craft powered by solar energy, designed to “hop” – or fly – short distances from the surface of the moon and land again. It will be used to explore the Shackleton Crater.

How do we know there is water on the moon?

Over the past two decades, several space missions have established that there is water on the moon.

Since the 1960s, even before the first Apollo landing in 1969, scientists speculated that water could exist on the moon. However, when Apollo crews returned samples for testing in the late 1960s and early 1970s, they appeared to be dry.

Finally, in 2009, NASA deliberately crashed a rocket segment and its probe into a shadowed lunar crater to analyse the dust plume it kicked up. This provided one of the clearest direct confirmations that significant ice water does exist on the moon, building on earlier detections of water and hydrogen by probes.

In October 2020, NASA scientists announced that water on the moon is more widespread than previously known. They said water molecules had been found to be encapsulated within mineral grains on the lunar surface and speculated that more water is hidden in ice patches which are in permanent shadows.

NASA describes these permanent shadows as dark areas inside deep craters near the north and south poles of the moon where sunlight has not reached for millions or even billions of years. In 2018, prior to confirming it in 2020, NASA had detected water ice in shadowed parts of the moon through mapping.

Why is it important to find out more about the water on the moon?

Expanding knowledge about water on the moon is vital because ancient polar ice may have preserved a record of lunar volcanic activity and of water delivered by comets and asteroids to the Earth-moon system, offering clues to how our own oceans originally formed.

Additionally, if there is enough water on the moon that is realistically accessible, it could serve as a source of drinking water for crewed lunar missions, and could also help to keep equipment cool.

Hydrogen could also be extracted from moon water to provide fuel, while oxygen could be extracted to breathe, supporting onward missions to Mars or lunar mining.

Could anyone ‘own’ the water on the moon?

The 1967 United Nations Outer Space Treaty bans any nation from claiming sovereignty over the moon or owning it as territory. It does not explicitly prohibit commercial operations, but it requires private activities in space to be authorised and supervised by states and leaves key questions about resource ownership unresolved.

Which recent space missions have searched for frozen water on the moon?

In 2023, Russia’s lunar spacecraft, Luna-25, was launched to look for frozen water in the moon’s south pole. However, the Luna-25 spun out of control and crashed. The crash prevented any scientific data collection or water discovery.

Racing against the Luna-25 mission was India’s Chandrayaan-3, which also aimed to expand knowledge of lunar water ice. Chandrayaan-3 successfully landed in August 2023 and found critical new evidence of water on the surface of the moon’s south pole through soil temperature readings.

Why is exploring the moon’s south pole a challenge?

Attempted landings at the moon’s south pole have failed before because of its challenging terrain, which is full of craters and deep trenches.

The south pole is far from the equatorial region targeted by previous missions, including the crewed Apollo landings.

What is different about the Chang’e-7 mission?

The upcoming Chang’e-7 is aiming to expand knowledge about where, exactly, water is located in the craters of the moon, how deep it is, what form it is in and whether it is indeed possible to access it.

The Chang’e-7’s six-legged hopper has been designed to jump into and out of the deep, shadowed craters near the south pole that are hard for traditional rovers to reach, to look for water ice and other resources.

No previous space mission has used a dedicated hopper to jump in and out of lunar craters in this way.

The government has announced investments of about 2.3 billion reais ($444.2m) to bolster its artificial intelligence ecosystem.

Brazil will invest about 2.3bn reais ($444.2m) to bolster its artificial intelligence ecosystem, splitting projects between United States and Chinese tech firms in a strategic move that underscores its efforts to balance ties with both superpowers.

Just more than half the total, 1.3bn reais ($251m), will fund a supercomputing infrastructure project in Rio de Janeiro developed in partnership with China’s Huawei Technologies and iFlytek, President Luiz Inacio Lula da Silva‘s government said on Thursday.

The infrastructure will be used primarily to develop large language models for general and sector-specific applications, it said.

Separately, about 1 billion reais ($193.1m) will be allocated through a tender for a supercomputer that Brazil expects to rank among the world’s 10 most powerful AI processing machines.

The machine will be installed in the northeastern state of Rio Grande do Norte, chosen for its energy potential. Lula attended an announcement ceremony in the state on Thursday.

The Reuters news agency quoted unnamed government officials as saying they expect US chipmaker Nvidia to win the tender. Science and Technology Minister Luciana Santos told the Folha de S Paulo newspaper last week that she anticipated the company would be the supplier.

“The strategy is not to depend on a single company, technology or country,” Lula’s administration said in a statement, adding that the investments are aimed at strengthening national sovereignty over data.

China, a leading player in AI, has expanded its role as Brazil’s largest trading partner. The US, meanwhile, remains the biggest source of foreign direct investment in Latin America’s largest economy despite losing market share in trade and recently imposing additional tariffs on Brazilian goods.

The investments will be funded by the National Fund for Scientific and Technological Development (FNDCT) through phased disbursements. The government expects the supercomputer to begin operating by the end of next year, while the cooperation agreement with the Chinese companies is scheduled to start in July 2027.

The biggest danger facing mankind is a machine that can “outsmart the whole species”, argues Max Tegmark, professor of physics at the Massachusetts Institute of Technology and founder of the Future of Life Institute.

Tegmark tells host Steve Clemons that governments and tech companies are in a “race to replace” human labour, instead of solving human problems. “It’s aimed at getting more money and power to a very small number of individuals,” he says.

But a slew of suicides and murders committed by people chatting with AI chatbots has led to pushback against the Silicon Valley “don’t regulate us” lobby.
