Despite the quotas and positive discrimination, many black Brazilian professionals still struggle to feel accepted and get promoted.

Ivana Davidovic hears from Luiza Trajano - Brazil’s richest woman and the owner of the country’s largest retailer, Magazine Luiza - who explains why she decided to launch a coveted management trainee scheme for black people only. Former model and director of the Identities of Brazil Institute NGO, Luana Genot, talks about her own experiences of being held back because of the colour of her skin and her work helping companies change their culture around black staff.

Alabe Nujara recalls being the first in his family to go to university and feeling out of place as a black man, which inspired him to successfully campaign for the introduction of quotas for historically disadvantaged students at federal institutions. Plus Brazilian sociologist Graziella Moraes Silva discusses why Brazil has an image of a racially inclusive society, which many black people would not recognise as their reality.

People across Europe are opening up their homes and businesses to Ukrainians as the refugee crisis tops 3 million. Ivanka, a Ukrainian social worker who has fled to Poland, tells us about the generosity of hotelier Dorota Baranska, who is now housing her and hundreds of other refugees in her hotels. And Eugen Comandent, COO of Purcari Wineries in Moldova, explains why his company has transformed its estate into a refugee centre. Matthew Saltmarsh from the UN’s refugee agency says this is Europe’s worst refugee crisis since World War Two and that generous countries on Ukraine’s border are starting to run out of resources. But some people based farther west are trying to create virtual ways to help. Ivan Kychatyi, a Ukrainian based in Berlin, has created the job portal UAtalents.com to that helps Ukrainians who are internally displaced or who have fled the country to find a job. And in Amsterdam, Guido Baratta has set up Designers United for Ukraine, specifically to help Ukrainians in the creative industries find work.

What now for Chelsea FC? After the UK government imposed sanctions on Russian owner Roman Abramovich, the club has been denied access to the funds that enabled investment in some of the world's best players and helped it become one of the biggest clubs in European football. No income, either, from ticket or merchandise sales can be made by the club, throwing its short term future into doubt. It's unclear whether Chelsea can even pay its squad and staff next month, such is the punishing nature of the sanctions put upon Mr Abramovich over his ties to the Kremlin and Vladimir Putin in the wake of Russia's invasion of Ukraine. So how will this play out on and off the pitch? We speak to Kieran Maguire who lectures in football finance at the Liverpool University; Justine Walker, an anti-money-laundering compliance specialist based in the UK; Jai McIntosh, a sports writer and Chelsea fan and former Chelsea player Pat Nevin. The programme is presented by Ed Butler and is produced by Elizabeth Hotson and Russell Newlove.

Financial sanctions are being used against Russia for its invasion of Ukraine so we’re exploring the role of cryptocurrency in the war. Is crypto being used to evade sanctions as assets are sezied and bank transactions blocked? Or is it simply a means of survival for millions of people in the region who can’t access any other forms of money? We find out by talking to Gaby Hui from Merkle Science, former US government advisor Ari Redbord head of legal and government affairs at TRM labs, Artem Afian a Ukrainian lawyer who has compiled a blacklist of crypto wallets connected to Russian politicians, Sir Julian Lee, former EU commissioner for the Security Union and Sandra Ro, CEO of the Global Blockchain Business Council - a non-profit organisation focused on developing the blockchain industry.

As Russia’s war in Ukraine continues, people across the country prepare for the possibility of a long, drawn out conflict.. Some, are determined to help their loved ones survive. But sending aid to a war zone isn't easy. Not just because access to cash locally is often hard to come by, but rules around fundraising are complicated.

Olia Hercules, cookbook author and chef, explains how, over the past two weeks, she’s rushed to fundraise and send protective gear to her brother fighting on the front lines in Kyiv. Like so many others, she ran into problems getting money where it needed to go. James Maloney, a partner at London-based law firm Farrer & Co. tells of the legal parameters charities can operate and fundraise for relief efforts. And, we hear from Mike Noyes, director of humanitarian aid at Action Aid UK who is leading the effort to help women and children fleeing the war at Ukraine’s border with Poland.

Munitions, equipment losses, sanctions, isolation - Vladimir Putin's decision to invade has come with a rapidly increasing price tag. Just the cost of prosecuting the war is proving astronomical, as Edward Arnold of military think tank RUSI tells Ed Butler.

Then there's the economic blowback - the freezing of the central bank's reserves, the exclusion from international finance, the boycotting by key international companies. Over the coming months, Russian industry could grind to a halt, while citizens could face food shortages, according to economist Maxim Mironov of IE Business School.

Take the example of aviation - soon half the planes in Russia could be grounded for lack of spare parts, says consultant Rob Watts of ACC Aviation. But will this be enough to convince Putin and the political elite around him to pull out of Ukraine? The Ukrainian political scientist Olga Chyzh says don't hold your breath.

Recent floods in eastern Australia have caused devastating losses of life and livelihoods. The BBC's Vivienne Nunis visits southeast Queensland and northern New South Wales where the damage bill from torrential rain is said to be in the billions of dollars. Climate change means natural disasters are becoming more frequent but that means insurance premiums are now too costly for many. So what can be done to prevent future disasters causing so much damage to businesses and homes? Picture: flood-damaged belongings piled up outside homes in Tumbulgum, NSW, Australia. Credit: BBC

A race is on to spot and catch some of the world's biggest and most dazzling yachts owned by Russian oligarchs with ties to President Vladimir Putin in retaliation for the Kremlin's invasion of Ukraine. Several of these multi-million dollar floating assets have been seized by US and European governments. But it's proving difficult to track the vessels, and then there is the issue of what to do with them, often with crew of up to 60 personnel on board. Ed Butler talks to sanctions lawyer Nigel Kushner of WLegal, Alex Finley, writer, former CIA officer and superyacht watcher, Graham Barrow a veteran money-laundering expert and journalist Jack Hogan of Superyacht News.

Food price inflation was already a problem. Could the conflict make things even worse?

Ukraine and Russia are both major food exporters. Tamasin Ford looks at how the war in Ukraine is affecting global prices.

Food price inflation was already a major problem in many parts of the world, and there are fears that the conflict will make matters even worse.

David Beasley, Executive Director of the World Food Programme, says millions of people in Ukraine will now be at risk of food insecurity as a result of the conflict, and fears knock-on effects for countries such as Lebanon, Syria and Tunisia, which are major importers of grains from Ukraine.

Ivanna Dorichenko, managing director of consultancy firm TRADAIDE and an expert in international arbitration, says the situation in Ukraine is devastating, and that much of the country’s agricultural infrastructure has been destroyed by the Russian invasion.

Andrey Sizov, head of research firm SovEcon, is an expert on agriculture in the Black Sea region. He says the war in Ukraine is already paralysing exports , with shipping companies refusing to send vessels into areas potentially disrupted by the conflict

Wandile Sihlobo, chief economist of the Agricultural Business Chamber of South Africa, says the conflict will have an impact on African countries which buy grains from Ukraine, many of which were already struggling with rising food prices.

On Business Weekly this week, as the fighting in parts of Ukraine intensified, a suite of sanctions has been levied on Russia, cutting off the country from the inter-bank messaging system Swift and restricting access to the foreign reserves Russia holds in the West’s central banks. Many large international companies are scaling down their businesses in Russia, including the oil giants BP and Shell. The global shipping giant Maersk is stopping its ships from docking at Russian ports. Chris Weafer, chief executive of Macro Advisory and a 24-year resident of Moscow tells us what life is like for ordinary Russians. Meanwhile, author and journalist Oliver Bullough tell us how badly the oligarchs will be hit by the sanctions. We also look at the impact of the conflict on Russian and Ukrainian grain exports, particularly for countries in Africa and Southeast Asia that already suffer from food insecurity. And we hear about the parallel cyberwar that’s taking place to the one on the ground. Hundreds of thousands of hackers are thought to have signed up to an online army to target Russian banks and institutions. Plus, we analyse Russia’s relationship with Africa. Steven Gruzd from the South African Institute of International Affairs in Johannesburg tells us about the extent of Russian military and economic influence in Africa, and how that influence goes some way to explain why so many countries in the region did not to lend their support to the UN draft resolution condemning Russia’s aggression Ukraine.
