As pressure to tackle London's housing crisis grows, a number of controversial views are being offered on how the problem should be addressed. By Andy DangerfieldBBC News, London 'House prices soar'. 'Fears of a housing bubble'. 'First-time buyers priced-out'. These are familiar headlines to Londoners. Each has appeared in the press in the past month, but similar headlines have become all-too recognisable over the past couple of years. London's house prices are rising by more than 20% annually, according to latest Office for National Statistics figures. The city needs 63,000 new homes each year, but only a third of these are being built while a "lost generation is being ruled out of ownership" due to "soaring rents, poor conditions and rising homelessness", it has been claimed. But what alternative solutions are being put forward to tackle the issue? Move old people to smaller flats One in four children in London live in overcrowded homes, according to English Housing Survey figures. At the same time, thousands of single elderly people live alone in multi-bedroomed suburban properties. In 2012, Local Government Association president Lord Richard Best proposed a radical solution: Building 100,000 homes designed especially for the needs of an ageing population. By downsizing, older people could free up accommodation for families, helping a whole generation of first-time buyers who are priced out of the market. "We free up lots of family housing, and we look after ourselves when we're older because, sooner or later, those three-bedroom, four-bedroom family houses are going to be too much for us," Lord Best said. But how easy would it be to convince elderly people to move out of the home they may have lived in for most of their lives? Peter Girling, chairman of Girlings Retirement Rentals, suggested the government should offer tax breaks to elderly people who give up their property. "You can't force people to move but you could help them along the way," he said. Adopt a European attitude Perhaps we should just face the fact the golden age of home ownership might be over, and learn to rent like the Germans? According to the 2011 German census, only 16% of Berliners owned their own place, compared with 50% in London. "People in Germany or Paris live in rented accommodation for their entire lives and there's no stigma attached," said Patricia Brown, who chairs the London Festival of Architecture. She said following the example of Germany and enabling people to rent better properties for longer could be a solution. For instance, in Germany tenants can only be evicted with a minimum of three months' notice. London's mayor Boris Johnson launched a voluntary accreditation scheme aimed at improving rental standards in May. In order to be approved for the London Rental Standard, landlords are required to meet a set of commitments including "transparent fees" and "improved response times for repairs". But Labour's London Assembly housing spokesman Tom Copley thinks the scheme does not go far enough. He suggested three-year tenancies "as standard with caps on annual rent increases" would make "renting in London more stable". Build all over the green belt There is still plenty of green belt land within the M25 and Sam Bowman, a research director at pro free market think-tank The Adam Smith Institute, thinks maybe the time has come to build on it. As of 2010, London had 484,173 hectares of green belt - 3.7% of England's total land area, according to the Campaign to Protect Rural England. Mr Bowman said this would mean "bigger homes and cheaper homes for everybody in order to give people that space to live". But Ann Goddard, of Elstree & Borehamwood Greenbelt Society, said: "Green belt is very important. You only have to look at the English countryside. It's so pretty." Ms Goddard, who lives in the green belt in Hertsmere, Hertfordshire - 12 miles (19km) north-west of central London and within the M25 - added: "We need green spaces for recreation purposes and to make a demarcation between the settlements." Mr Bowman suggested a compromise could be reached "if we stopped thinking of the greenbelt as one single unit and differentiate between the areas of beauty and the intensive farmland". Penalise owners of empty properties Perhaps there is not a shortage of homes for Londoners after all. More than 80,000 homes in the capital currently stand empty. Last year, councils were empowered to use the Empty Homes Premium to charge home owners 50% more council tax if they left properties empty for two or more years. But the results of a Freedom of Information request published by BBC London last week showed that just 4,399 of the 80,489 empty properties in the capital had been subjected to the Empty Homes Premium. Responding to the revelations, Labour leader Ed Miliband said he was "deeply concerned". But Daniel Astaire, Westminster Council's Conservative cabinet member for housing, said: "The way to build homes is not to tax existing homes and stop people investing and buying in our city." Build on brownfield sites Building on brownfield sites - land previously used for industrial or commercial purposes - is possibly the least controversial solution on this list. In June, the Treasury announced 50,000 new London homes would be built on 20 such sites. But Mr Johnson has said the scheme is a "just a fraction of what needs to be done". The mayor has said 49,000 homes need to be built in the capital each year, while Labour puts this figure at 63,000. But developers face problems. Brownfield land is often contaminated and expensive to clean, getting planning permission to build can be a lengthy and costly process and putting in new roads and train links can prove tricky. But Lib Dem London Assembly member Stephen Knight said what was important was the type of homes that were built. "We need changes to planning laws, so the government can determine certain plots of land should be used for affordable housing," he suggested.

Penalise owners of empty properties Perhaps there is not a shortage of homes for Londoners after all. More than 80,000 homes in the capital currently stand empty. Last year, councils were empowered to use the Empty Homes Premium to charge home owners 50% more council tax if they left properties empty for two or more years. But the results of a Freedom of Information request published by BBC London last week showed that just 4,399 of the 80,489 empty properties in the capital had been subjected to the Empty Homes Premium. Responding to the revelations, Labour leader Ed Miliband said he was "deeply concerned". But Daniel Astaire, Westminster Council's Conservative cabinet member for housing, said: "The way to build homes is not to tax existing homes and stop people investing and buying in our city." Build on brownfield sites Building on brownfield sites - land previously used for industrial or commercial purposes - is possibly the least controversial solution on this list. In June, the Treasury announced 50,000 new London homes would be built on 20 such sites. But Mr Johnson has said the scheme is a "just a fraction of what needs to be done". The mayor has said 49,000 homes need to be built in the capital each year, while Labour puts this figure at 63,000. But developers face problems. Brownfield land is often contaminated and expensive to clean, getting planning permission to build can be a lengthy and costly process and putting in new roads and train links can prove tricky. But Lib Dem London Assembly member Stephen Knight said what was important was the type of homes that were built. "We need changes to planning laws, so the government can determine certain plots of land should be used for affordable housing," he suggested.

Here is an summary requirement:
Summarize the option of building more properties on green belt lands as a solution.

Please summarize the above article based on the given requirement:

# Output (a):
Research director at The Adam Smith Institute, Sam Bowman, suggests that building on London's green belt lands could provide bigger and cheaper homes for everyone. However, Ann Goddard of Elstree & Borehamwood Greenbelt Society argues that green belt lands are important for recreation purposes and to maintain a separation between settlements. Bowman proposes a compromise by differentiating between areas of beauty and intensive farmland within the green belt.

# Output (b):
One solution to London's housing crisis that has been proposed is to build more homes on green belt land. This would mean more homes for Londoners, but it would also mean sacrificing some of the city's green spaces.

As pressure to tackle London's housing crisis grows, a number of controversial views are being offered on how the problem should be addressed. By Andy DangerfieldBBC News, London 'House prices soar'. 'Fears of a housing bubble'. 'First-time buyers priced-out'. These are familiar headlines to Londoners. Each has appeared in the press in the past month, but similar headlines have become all-too recognisable over the past couple of years. London's house prices are rising by more than 20% annually, according to latest Office for National Statistics figures. The city needs 63,000 new homes each year, but only a third of these are being built while a "lost generation is being ruled out of ownership" due to "soaring rents, poor conditions and rising homelessness", it has been claimed. But what alternative solutions are being put forward to tackle the issue? Move old people to smaller flats One in four children in London live in overcrowded homes, according to English Housing Survey figures. At the same time, thousands of single elderly people live alone in multi-bedroomed suburban properties. In 2012, Local Government Association president Lord Richard Best proposed a radical solution: Building 100,000 homes designed especially for the needs of an ageing population. By downsizing, older people could free up accommodation for families, helping a whole generation of first-time buyers who are priced out of the market. "We free up lots of family housing, and we look after ourselves when we're older because, sooner or later, those three-bedroom, four-bedroom family houses are going to be too much for us," Lord Best said. But how easy would it be to convince elderly people to move out of the home they may have lived in for most of their lives? Peter Girling, chairman of Girlings Retirement Rentals, suggested the government should offer tax breaks to elderly people who give up their property. "You can't force people to move but you could help them along the way," he said. Adopt a European attitude Perhaps we should just face the fact the golden age of home ownership might be over, and learn to rent like the Germans? According to the 2011 German census, only 16% of Berliners owned their own place, compared with 50% in London. "People in Germany or Paris live in rented accommodation for their entire lives and there's no stigma attached," said Patricia Brown, who chairs the London Festival of Architecture. She said following the example of Germany and enabling people to rent better properties for longer could be a solution. For instance, in Germany tenants can only be evicted with a minimum of three months' notice. London's mayor Boris Johnson launched a voluntary accreditation scheme aimed at improving rental standards in May. In order to be approved for the London Rental Standard, landlords are required to meet a set of commitments including "transparent fees" and "improved response times for repairs". But Labour's London Assembly housing spokesman Tom Copley thinks the scheme does not go far enough. He suggested three-year tenancies "as standard with caps on annual rent increases" would make "renting in London more stable". Build all over the green belt There is still plenty of green belt land within the M25 and Sam Bowman, a research director at pro free market think-tank The Adam Smith Institute, thinks maybe the time has come to build on it. As of 2010, London had 484,173 hectares of green belt - 3.7% of England's total land area, according to the Campaign to Protect Rural England. Mr Bowman said this would mean "bigger homes and cheaper homes for everybody in order to give people that space to live". But Ann Goddard, of Elstree & Borehamwood Greenbelt Society, said: "Green belt is very important. You only have to look at the English countryside. It's so pretty." Ms Goddard, who lives in the green belt in Hertsmere, Hertfordshire - 12 miles (19km) north-west of central London and within the M25 - added: "We need green spaces for recreation purposes and to make a demarcation between the settlements."

Adopt a European attitude Perhaps we should just face the fact the golden age of home ownership might be over, and learn to rent like the Germans? According to the 2011 German census, only 16% of Berliners owned their own place, compared with 50% in London. "People in Germany or Paris live in rented accommodation for their entire lives and there's no stigma attached," said Patricia Brown, who chairs the London Festival of Architecture. She said following the example of Germany and enabling people to rent better properties for longer could be a solution. For instance, in Germany tenants can only be evicted with a minimum of three months' notice. London's mayor Boris Johnson launched a voluntary accreditation scheme aimed at improving rental standards in May. In order to be approved for the London Rental Standard, landlords are required to meet a set of commitments including "transparent fees" and "improved response times for repairs". But Labour's London Assembly housing spokesman Tom Copley thinks the scheme does not go far enough. He suggested three-year tenancies "as standard with caps on annual rent increases" would make "renting in London more stable". Build all over the green belt There is still plenty of green belt land within the M25 and Sam Bowman, a research director at pro free market think-tank The Adam Smith Institute, thinks maybe the time has come to build on it. As of 2010, London had 484,173 hectares of green belt - 3.7% of England's total land area, according to the Campaign to Protect Rural England. Mr Bowman said this would mean "bigger homes and cheaper homes for everybody in order to give people that space to live". But Ann Goddard, of Elstree & Borehamwood Greenbelt Society, said: "Green belt is very important. You only have to look at the English countryside. It's so pretty." Ms Goddard, who lives in the green belt in Hertsmere, Hertfordshire - 12 miles (19km) north-west of central London and within the M25 - added: "We need green spaces for recreation purposes and to make a demarcation between the settlements." Mr Bowman suggested a compromise could be reached "if we stopped thinking of the greenbelt as one single unit and differentiate between the areas of beauty and the intensive farmland". Penalise owners of empty properties Perhaps there is not a shortage of homes for Londoners after all. More than 80,000 homes in the capital currently stand empty. Last year, councils were empowered to use the Empty Homes Premium to charge home owners 50% more council tax if they left properties empty for two or more years. But the results of a Freedom of Information request published by BBC London last week showed that just 4,399 of the 80,489 empty properties in the capital had been subjected to the Empty Homes Premium. Responding to the revelations, Labour leader Ed Miliband said he was "deeply concerned". But Daniel Astaire, Westminster Council's Conservative cabinet member for housing, said: "The way to build homes is not to tax existing homes and stop people investing and buying in our city." Build on brownfield sites Building on brownfield sites - land previously used for industrial or commercial purposes - is possibly the least controversial solution on this list. In June, the Treasury announced 50,000 new London homes would be built on 20 such sites. But Mr Johnson has said the scheme is a "just a fraction of what needs to be done". The mayor has said 49,000 homes need to be built in the capital each year, while Labour puts this figure at 63,000. But developers face problems. Brownfield land is often contaminated and expensive to clean, getting planning permission to build can be a lengthy and costly process and putting in new roads and train links can prove tricky. But Lib Dem London Assembly member Stephen Knight said what was important was the type of homes that were built. "We need changes to planning laws, so the government can determine certain plots of land should be used for affordable housing," he suggested.

Here is an summary requirement:
Summarize the option of building more properties on green belt lands as a solution.

Please summarize the above article based on the given requirement:

Research director at The Adam Smith Institute, Sam Bowman, suggests that building on London's green belt lands could provide bigger and cheaper homes for everyone. However, Ann Goddard of Elstree & Borehamwood Greenbelt Society argues that green belt lands are important for recreation purposes and to maintain a separation between settlements. Bowman proposes a compromise by differentiating between areas of beauty and intensive farmland within the green belt.

One solution to London's housing crisis is to build more properties on green belt lands. This would mean bigger and cheaper homes for everyone, but there is opposition to this idea as green belt land is seen as important for recreation and to make a demarcation between settlements. A compromise could be reached by differentiating between areas of beauty and intensive farmland.

As Spain scrambles to save its vital tourism industry from the threat of a blank year due to the Covid-19 pandemic, some sense an opportunity to change perceptions about Spanish holidays and start a move upmarket that has been long on the agenda. By James BadcockMadrid If tourism is vitally important to the Spanish economy, accounting for 12% of GDP, nowhere is it more crucial than in the Balearic Islands, where it represents 35% of the region's economic output. Normally, June would see the beaches of Majorca, Ibiza and the archipelago's smaller islands busy with international tourists, who made up the bulk of the more than 16 million visitors the region received in 2019. This year only got started with a batch of just over 5,000 Germans, given special permission to stay in the Palma Beach resort on Majorca as a pilot scheme to test Spain's emergency protocols for safe tourism in the Covid-19 age. "We are very pleased with the pilot programme, and our customers have been able to see that holidays are possible with safety. "People are wearing face masks, there is hydro-alcoholic gel when you enter the restaurant, and in the bathroom the taps are electric so you don't have to touch them," says Juan Miguel Ferrer, chief executive of Palma Beach. "The peace and quiet is actually wonderful," tourist Martin Bröcker told German media. Praising the temperature checks at the airport and extra measures in the local hotels, he said: "whoever wants to go on holiday to Majorca has to help ensure there's no new outbreak." Quieter nightlife as the clubs stay silent Although flights to Majorca are expected to reach levels of 30% to 40% of a normal summer, the atmosphere at Palma Beach is set to remain considerably more sedate than other years. Mr Ferrer accepts that the Covid-19 effect will accelerate the existing tendency towards less nightlife and more daytime experiences. In June the Balearic Islands government announced that nocturnal excesses would not be a part of this summer. There are strict rules limiting opening times and conditions in pubs and clubs, and nightclubs are banned from operating at all in Magaluf and Palma Beach on Majorca as well as Sant Antoni on Ibiza - the resorts that have become notorious for so-called "booze tourism". "There won't be that kind of mass tourism because those places are not going to open; it's a clear message," says Iago Negueruela, the Balearic minister for the economy, labour and tourism. "We had already started a process and it is irreversible. The pubs won't open this year. We are no longer going to receive or tolerate that kind of tourist, who can be a risk for themselves and others." Mr Negueruela highlights the law against "tourism of excesses" that his government introduced at the start of the year, banning pub crawls and happy hours. End of an era for 'booze tourism'? The current situation can only accelerate the end of what he says is a mere remnant of a bygone age, the minister argues. "Our hotel sector has already staked out its preference for quality and not just numbers, but the perception does not always accompany the reality. Even in Magaluf, a transformation has been taking place, with a focus on five-star hotels, its beaches and gastronomy." Industry leaders recognise that Covid-19 may make crowding a taboo for all future visitors. "Some elements of this crisis might be temporary, like face masks," says Andreu Serra, tourism chief for the Mallorca Council island administration. "But this is also an opportunity to improve our care of tourists, by using technology to control numbers so we know when beaches will be full, and generally boosting hygiene in all hospitality areas." Time to turn away from tourism? Not everyone is sighing in relief at the return of tourists to Majorca and the other islands. Local environmentalists criticise the over-dependence on a sector that has transformed the archipelago's landscape, while creating employment that is largely low-paid and seasonal in nature as property prices and even rents skyrocket beyond the means of most employees. For Antoni Pallicer Mateu, a member of publishing collective Tot Inclòs that aim to inform on tourism's impact on the islands, Balearic citizens and in particular Majorcans have become prisoners to a sector "that is so vulnerable to instability" and whose use of resources is such that almost all other needs have to be imported. "Now it's a pandemic, but in the near future it could be a climate or energy crisis, or simply a crisis in our main markets of Germany and the UK," argues Mr Pallicer Mateu. "Tourism benefits tour operators, agencies, hotel chains, rental companies like Airbnb, and also a Majorcan middle class who own property and companies. But it is benefiting the working class and small businesses less and less. Mass tourism is driving us towards unsustainability and an environmental and even social collapse." In the Balearic high season, the population of the islands usually doubles due to tourism, as the one million residents are matched by a million tourists. Little wonder, then, that registered unemployment in May was double the normal amount for that month, at 75,000. "We have tourism dependency, and we will for another 15 years at least, because no other alternative has been developed," says Mr Ferrer, noting that the non-services part of the economy only covers 15% of Balearic GDP. "It's a moment of political opportunity to criticise tourism right now, but that's what is paying people's wages every month," Mr Ferrer continues. "I doubt many of our waiters and waitresses who have been out of work these past few months would subscribe to this point of view."
