ArtReview’s Power 100 is an annual ranking that identifies the individuals considered most influential in shaping the contemporary art world. Compiled by the UK-based magazine ArtReview, the list reflects impact across artistic practice, institutions, markets and cultural debate, rather than commercial success alone.

Images from Accra show sacks filled with coloured rocks and stones, labourers assembling large textile installations, and visitors moving through museum spaces where Mahama’s work is on display. His work is best known for monumental textile-based pieces made from repurposed jute sacks and industrial materials, which frequently address themes of labour, history and exploitation.

Mahama has argued that producing ideas from Africa inevitably shapes how those ideas resonate globally. He noted that while artists and students have traditionally looked towards the West for knowledge, the conditions on the continent also generate forms of understanding that cannot be created elsewhere.

The art ist said his decision to base his practice in Tamale was deliberate. Using a metaphor, he compared art to sugar that attracts ants wherever it is placed, explaining that building his studio there was less about location and more about contribution, learning and long-term engagement.

At 38, Mahama climbed from 14th place in the 2024 ranking to the top position this year. Over the past decade, his large-scale installations have brought him international attention, positioning his work at the centre of discussions about labour, responsibility, memory and the social implications of artistic production.

This trend shows how intensifying human activity is putting ever greater pressure on Earth’s water and land systems. But what’s driving this growth, and what does it mean for our future?

Several forces are pushing freshwater demand upward. Agriculture continues to be the heaviest water user globally. As food production expands to feed growing populations, more irrigation, fertilisers, and water-intensive crops are deployed.

Industry, too, plays a big role. Manufacturing, energy production, and processing all require water—not just for cooling and rinsing, but as a direct input into many industrial processes.

Urbanisation adds another layer of demand. As cities grow, water is needed not only for households, but for infrastructure , landscaping, public services, and sanitation.

Meanwhile, climate change adds uncertainty. Erratic rainfall, shifting weather patterns, and warming trends affect how much water is available, when, and where.

According to Our World in Data , global freshwater withdrawals have climbed sharply since the mid-20th century, though growth has begun to slow in some regions. Still, pressures remain high, especially in countries with limited renewable water resources.

A recent paper in MDPI highlights that shifts in water use efficiency, technological adoption, and policy interventions will be crucial for balancing demand with sustainability.

The UN World Water Development Report 2024 also emphasises water’s role not just in agriculture and industry, but in peace, stability, and equitable development. It argues that water, when managed fairly, can support social cohesion, but mismanagement can fuel conflicts.

These global dynamics don’t exist in a vacuum. In many parts of the world, water scarcity is already a driver of migration, social stress, and geopolitical tension. In the Horn of Africa, for example, prolonged droughts have contributed to displacement and competition over shared river systems.

Meanwhile, the push for green technology has implications for water use. Solar panel manufacturing, battery production, and data centres all demand water, sometimes in unexpected amounts.

In parts of Africa, researchers have begun estimating water consumption tied to computing infrastructure, underscoring how even digital growth is connected to natural resources.

The decisive goal came from Tottenham Hotspur midfielder Mohammed Kudus, whose strike ensured Ghana’s place in the tournament and marked the country's fifth World Cup appearance since its debut in 2006.

Ghana topped Group I in the African qualifiers with 25 points, finishing six points ahead of Madagascar. The Black Stars now join Algeria, Egypt , Morocco, and Tunisia as the African nations already qualified for the 2026 edition.

The 2026 FIFA World Cup, which will be the first to feature 48 teams, is set to be jointly hosted by the United States , Canada, and Mexico.
