The centralised regulation of electric power in Nigeria is stalling progress in the sector. To achieve stable power supply, the country must obey its constitution and decentralise regulation.
Greening cities have a huge impact. The trees go beyond just lowering temperatures. They help decrease the demand for indoor cooling like air-conditioners saving money.
Heavy rains, poor and clogged drainage systems have made many towns and cities in Nigeria susceptible to massive flooding.
Rare colour variants of hunted African species have been known for a long time. Trophy hunters seeking novelty might pay more to hunt these unusually coloured animals.
Exposure to neonicotinoids could lead to fewer bumblebee colonies, less pollination, and ultimately to population extinctions.
Many mammals depend on large areas and trans-boundary conservation for their survival. When this is obstructed it can have a catastrophic impact on animal populations.
Conservationists need to assess costs which allow for the adequate compensation of communities on protected lands, whose livelihoods are deeply entwined with forest use.
Agricultural pests are one of the key factors affecting small holder farmer production. Focus is normally put on invertebrate pests, but rodents can do severe damage to crops as well.
Most African cities are expensive, informal and non-industrial. This has produced unique socioeconomic and environmental risks that must be carefully considered in policy development.
Early warning signs of a pending drought are difficult to recognise but cities will have to be better prepared for prolonged changes in weather patterns, so that it can respond quickly.
Elephants feeding on crops poses a challenge to their coexistence with humans. Farmers must introduce strategies to reduce losses and avoid lethal action against the endangered species.
Global food system issues can be traced to colonial history. It's time food production became more sustainable so that it meets the needs of people - equally.
Invasive frogs can have a major impact on the environment. Some move continents by human trade or travel. But determining how to control them can lead to policies that limit their spread and effects.
The European goldfinch, with its wonderful coloration and melodic singing, is a favoured pet for people living in the western Maghreb. But continued poaching is putting the species in danger.
Captivity isn't kind to cheetahs where most develop diseases that are unusual in big cats. It's never been clear why this is the case, but understanding their metabolism might provide the answer.

Protecting rhinos and fighting terrorism are both noble causes, but there isn't much evidence of a link between the two.
There are rising concerns that rapid deforestation across the Amazon and Southeast Asia could spread to Africa. The continent hasn’t yet seen vast agricultural expansion but it could be on the way.
It's very easy to assume climate change causes droughts, but they are complex extreme events that result from a combination of drivers.
Forests and savannas are expected to be strongly affected in the coming decades by changing rainfall patterns. But land use will also have a major impact.
There is an increasing demand for water in cities like Cape Town. The current drought exacerbates this. But there are ways to use and save water sustainably.
The plastic bag ban doesn't consider the impact it will have on Kenya's economy or consider other environmental alternatives.
Building resilience in Cape Town's water sector will require addressing risks like climate change, drought and flooding. Stormwater and groundwater are tipped as potential solutions.
The land reform programme in Zimbabwe has come at the cost of wildlife and opens up the debate on people versus nature. But there is a way forward.
Demonstration farms are a key way in which new knowledge can be transferred to farmers around the world.
Eskom's stand threatens the viability of the entire renewable energy sector in South Africa, something which plays into the hands of those pro coal and nuclear.
Solar radiation management might be able to reduce some of the risks of global warming while countries get their emissions under control.
Africa's great green wall suffers from a major mismatch between ambition and effort. But that's not to say it should be ditched altogether.
US President Donald Trump’s call to renegotiate the Paris Climate Accord is a fresh opportunity to craft a binding and enforceable agreement.
