One of southern Africa’s biggest tourist attractions has seen an unprecedented decline this dry season, fuelling climate change fears

For decades Victoria Falls, where southern Africa’s Zambezi river cascades down 100 metres into a gash in the earth, have drawn millions of holidaymakers to Zimbabwe and Zambia for their stunning views.

But the worst drought in a century has slowed the waterfalls to a trickle, fuelling fears that climate change could kill one of the region’s biggest tourist attractions.

Victoria Falls, on the border of Zimbabwe and Zambia, has slowed down to a trickle after an unprecedented decline in water levels, officials have said. Data from the Zambezi River authority showed water flow at its lowest since 1995, and well under the long-term average. 

The Zambian president, Edgar Lungu, said it was a stark reminder of what climate change is doing to the environment, yet some scientists are cautious about categorically blaming the climate crisis. Harald Kling, a hydrologist at engineering firm Pöyry and a Zambezi River expert, said climate science dealt in decades, not particular years, 'so it’s sometimes difficult to say: this is because of climate change because droughts have always occurred'

New Zealand’s cabinet will meet on Monday to decide the future of the country’s tough but effective lockdown – though Kiwis have been told not to visit their mums this Mother’s Day.

Next week, Ardern’s government will plot a path back to something close to normality, meeting to decide a timetable for the removal of social and business restrictions. The prime minister has already released what level two restrictions will look like, including the re-opening of restaurants, hairdressers, gyms, cinemas and public facilities like museums and libraries.

Social restrictions could end immediately, with provisions for schools, business and personal movement more likely to be phased in.

Any decision will come too late for Kiwi mums to enjoy visits from sons and daughters not already in their household bubbles. Ardern has banned socialising outside of existing households, with few exceptions, and told Kiwis this week to “stick to the plan” ahead of Monday’s review.

Power struggle between Bashar al-Assad and first cousin sparks rare family fissure and leaves public aghast

A defiant tyrant and his ruthless wife square up against the family oligarch, with the spoils of a nation at stake. It could be standard Ramadan television fare, but not this year. Instead, all the intrigue of Syria’s ruling family has been laid out in a spectacular real-life drama that has gripped the country and the region.

Leading the cast is the Syrian leader, Bashar al-Assad, and Syria’s first lady, Asma al-Assad, but star billing has so far been taken by the president’s first cousin, Rami Makhlouf, who last week took to Facebook to do the unthinkable: air the normally inscrutable family’s dirty laundry.

Co-founder of the pioneering German electronic band Kraftwerk

As one of the chief architects of the electronic music pioneers Kraftwerk, Florian Schneider, who has died of cancer aged 73, helped revolutionise popular music. Where guitars, bass and drums had long been considered its essential building blocks, Kraftwerk paved the way for synth-pop, techno, hip-hop and electronica, in the process proving that microchips and machines could have not only soul, but a sense of humour too. The list of artists whose work is indebted to Kraftwerk, even if they did not always know it, is endless, but includes David Bowie, Depeche Mode, Simple Minds, New Order, The Orb, Madonna, Neil Young, Jay-Z, Afrika Bambaataa, Coldplay and Daft Punk. In 1997 the New York Times described Kraftwerk as “the Beatles of electronic dance music”.

With Schneider and Ralf Hütter proving the main creative impetus, Kraftwerk (German for “power station”) reached their pivotal moment with the release of their fourth album, Autobahn (1974), whose 23-minute title track – a euphoric electronic ode to the joys of driving on Germany’s high-speed motorways, delivered with a light and whimsical touch – became emblematic of the group’s sound and approach. The album reached No 4 in Britain, while the single version of Autobahn reached the the UK Top 20 and the German Top 10. This revolution in synthetic music earned Kraftwerk a spot on BBC television’s science programme Tomorrow’s World in 1975. They subsequently scored a UK chart-topping single, The Model, released with Computer Love (1981), but Kraftwerk’s influence was much further-reaching than mere chart positions would suggest.

With so many conversations now happening online, all eyes are on our decor. It may even help me find a buyer for my strange yellow filing cabinet

An awful lot is being made of what is on the bookshelves behind people who broadcast or are interviewed in their homes. Thankfully, mine are at a right angle to the computer so you cannot see any of the titles. In fact, until adjustments were made, it looked as though the shelves were completely empty, which was rather shaming. The books had to be pulled forward, to make it clear they existed, without compromising their anonymity.

I was keen to have a nod to my football team, West Bromwich Albion, in the back of shot. A scarf seemed a bit naff, and my treasured West Brom gnome just too odd. I even considered a jigsaw puzzle of the face of one of our greatest ever players, Tony “Bomber” Brown. Unfortunately Bomber, as gentle a man as you could ever meet, looks like a serial killer in this particular picture.
