WRI’s Aqueduct project recently evaluated, mapped, and scored water risks like these in 100 river basins, ranked by area and population, and 181 nations—the first such country-level water assessment of its kind. We found that 37 countries face “extremely high” levels of baseline water stress (see list at bottom). This means that more than 80 percent of the water available to agricultural, domestic, and industrial users is withdrawn annually—leaving businesses, farms, and communities vulnerable to scarcity.
In much of Africa, the bundle of land rights that most rural people legally hold is relatively small—usually limited to surface rights and certain rights to some natural resources on and below the surface, such as rights to water for domestic use. Many high-value natural resources—such as oil, natural gas, minerals, and wildlife—are governed by separate legal regimes and administered by different public institutions. Africa’s governments often allocate these rights to outside, commonly foreign companies for large-scale operations. In other words, while many communities hold rights to the land, foreign companies hold the rights to the natural resources on or under the same plot. These overlapping rights oftentimes lead to conflict, unsustainable use of resources, and injustices.
New research shows that Bus Rapid Transit (BRT) can reduce travel time by millions of hours for commuters worldwide. For instance, BRT users in Istanbul, Turkey, can save 28 days per year by shifting from other transport modes to BRT. Commuters in Johannesburg, South Africa, meanwhile, can save an estimated 73 million hours between 2007 and 2026. That’s the equivalent of more than 9 million eight-hour work-days.
The world is projected to hold a whopping 9.6 billion people by 2050. Figuring out how to feed all these people—while also advancing rural development, reducing greenhouse gas emissions, and protecting valuable ecosystems—is one of the greatest challenges of our era.
So what’s causing the global food challenge, and how can the world solve it? We begin to answer these questions through a series of graphics below.
