Question 1

According to a recent comprehensive study published in Nature, what percentage of biodiversity has Sub-Saharan Africa lost since pre-industrial times, and what is a key implication regarding the location of remaining wild flora and fauna?

Accepted Answer

Nearly a quarter (24%) lost; 80% of remaining species live outside formally protected lands.

Question 2

What is a primary driver of deforestation in Sub-Saharan Africa, accounting for approximately 75% of forest loss, and what is a critical consequence highlighted by recent research concerning mining activities?

Accepted Answer

Agricultural expansion; for every hectare of mine site, 34 hectares of forest are lost to supporting infrastructure.

Question 3

In 2025, African countries added a significant amount of renewable energy capacity. How much capacity was added, and what trend is observed regarding new energy projects announced across Africa in the same year concerning renewables versus fossil fuels?

Accepted Answer

11.3 gigawatts added; 253 were renewable energy projects, including 173 solar installations, with only 22 natural gas projects announced.

Question 4

The African Development Bank (AfDB) has been increasing its climate finance. In 2024, what amount did the AfDB allocate to climate finance, and what percentage of its total approvals did this represent?

Accepted Answer

$5.5 billion; 49% of total approvals.

Question 5

What is the estimated annual economic loss for Sub-Saharan Africa due to poor water infrastructure, and what is the estimated return on investment for every dollar spent on water and sanitation improvements?

Accepted Answer

5% of GDP, equivalent to $170 billion per year; at least seven dollars in benefits.

Question 6

A 2025 study highlighted that 80% of Sub-Saharan Africa's remaining wild plants and animals live outside formally protected lands. What is a significant implication of this finding for biodiversity conservation strategies?

Accepted Answer

It highlights the insufficiency of protected areas alone and the need for sustainable management of working landscapes.

Question 7

According to recent data, by what year are glaciers in several major African mountains, including Mount Kilimanjaro, expected to vanish entirely, and what is a major consequence of this phenomenon?

Accepted Answer

2050; jeopardizing water supplies for millions.

Question 8

In 2025, what was the estimated renewable energy capacity added by African countries, and how does this compare to the capacity added in 2024?

Accepted Answer

11.3 gigawatts, an increase from 4.2 gigawatts in 2024.

Question 9

What is the primary challenge hindering the significant deployment of utility-scale wind and solar PV facilities in many Sub-Saharan African countries, despite the potential for renewables?

Accepted Answer

Electricity utilities lacking investment-grade credit ratings and other investment disincentives.

Question 10

Recent research indicates that between 2001 and 2020, a significant area of forest was lost to mining activity in Africa. What was this area, and what is the ratio of forest loss due to supporting infrastructure compared to the mine site itself?

Accepted Answer

187,000 hectares; 34 hectares lost for every 1 hectare of mine site.
