New killer diseases are emerging faster than ever across the world, says the World Health Organization. In its report, "A Safer Future", experts highlighted several major threats to our health in the 21st century. But what are they?
More people left the UK last year than in any year since current records began in 1991, statistics show.Figures from the Office for National Statistics (ONS) indicate that some 385,000 people left the UK for the long term in the year to mid-2006.
n mid-2006 the resident population of the UK was 60,587,000, of which 50,763,000 lived in England. The average age was 39.0 years, an increase on 1971 when it was 34.1 years. In mid-2006 approximately one in five people in the UK were aged under 16 and one in six people were aged 65 or over.
The UK has a growing population. It grew by 349,000 people in the year to mid-2006 (0.6 per cent). The UK population has increased by 8 per cent since 1971, from 55,928,000. Growth has been faster in more recent years. Between mid-1991 and mid-2006 the population grew by an average annual rate of 0.4 per cent and the average growth per year since mid-2001 has been 0.5 per cent.

The AfriCat Foundation was founded in 1991 and officially registered as a non-profit organisation in August 1993. AfriCat has grown significantly since then and what started out primarily as an animal welfare organisation has over the years, identified the need to include a focus on education and research as being essential to our mission – the long-term conservation of large carnivores in Namibia.
The AfriCat Foundation concentrates on four objectives in working towards its mission:
• To create awareness and promote the tolerance of large carnivores among the farming community by assisting farmers in effective farm management techniques, including targeting problem predators as opposed to indiscriminate removal.
• To educate youth about large carnivores and environmental awareness.
• To research large carnivores, particularly cheetahs and leopards, on farmland and in captivity.
• To provide humane housing, treatment and care for orphaned and injured animals.

ECO-TOURISM PARTNERSHIP BETWEEN BAOBAB EXPEDITIONS AND THE AFRICAT FOUNDATION
AfriCat is pleased to announce its latest eco-tourism/wildlife conservation partnership with Baobab Expeditions – specialists in luxury travel adventures.
Baobab Expeditions has pledged to donate £110 to AfriCat for each of its travellers that stay in one of the four lodges at Okonjima – the home of the AfriCat Foundation. The travellers will choose whether this gift is spent adopting one of the large carnivores in AfriCat's welfare programme or providing general support for the foundation's work to resolve the conflict between predators and farmers. During their stay at Okonjima they will have the opportunity to witness some of AfriCat's work and see some of the big cats in the welfare and rehabilitation programmes. The Baobab Expedition travellers will also become members of AfriCat UK for one year, free of charge.
Baobab Expeditions promotes tourism as an economic engine, enabling individuals to experience a wild and free Africa. Support through travel is a direct channel for lending a hand and raising the public's awareness of the conflict between predators and the farming community and the vulnerability of the future populations of these cats.
The Baobab Expeditions' philosophy encapsulates the three principles at the heart of AfriCat's work: care of the wildlife, care of the people and care of the land. For more information please see www.baobabexpeditions.com

The Pasha Bulker wound up in this condition near Newcastle, Aus, for almost the entire month of June. Their mistake: ignoring warnings to head out to sea in advance of a major storm.
By the time they were grounded, they had to actually further ground it in advance off yet another storm. They pushed it parallel to the beach, so that it wouldn't sink entirely and release 700,000 tons of fuel oil into the water.
Five years after the concept was first proposed, the so-called $100 laptop is poised to go into mass production.Hardware suppliers have been given the green light to ramp-up production of all of the components needed to build millions of the low-cost machines. Previously, the organisation behind the scheme said that it required orders for 3m laptops to make production viable. The first machines should be ready to put into the hands of children in developing countries in October 2007.

This very high resolution image of northern Republic of Congo was captured on June 27, 2002, by the commercial satellite Ikonos. The wider-area view at top shows dirt logging roads (orange lines) and different types of forest in the area around the border of the Sangha and Likouala regions. The lower view is a close-up image that shows not only part of a logging road, but also felling sites (clearings where trees are cut down) and skid trails (paths where trees are dragged toward the road.) Individual trees or sections of trees stacked on the road at left look like matchsticks.
Two types of forest are shown in the top image. At bottom left is a tropical evergreen forest with an extremely dense canopy, a forest type known locally as limbali forest. Most of the rest of the scene is occupied by a more open forest in which stands of trees (dark green patches) are separated from each other by a sea of lower-growing plants (light green)

Geography has transformed as a university subject over the last decade. It is now a truly multidisciplinary subject tackling issues from urban regeneration to climate change and globalisation. As a result, almost all universities and colleges offer degree courses on some aspects of these areas. Courses listed here can vary enormously in their content. University College London emerges as the best ranked teaching course, leading a group of old universities at the head of the table, including Nottingham, Cambridge, Leeds and Oxford.
Geographers long agreed that, while the Amazon might be the world’s largest river by volume, the longest was likely the Nile. In 2007, however, the BBC reported that a team of Brazilian researchers challenged that long-held belief. After an expedition to Peru to locate the Amazon’s precise source, the team described a different starting point. The team claimed that the river originated not in northern Peru, where it had been thought to begin, but in southern Peru, somewhere on snowcapped Mount Mismi (or Nevado Mismi). The team narrowed down the starting point to one of two places, but concluded that either one would nudge the Amazon’s length past that of the Nile
Thanks for Val Vannet for this find. Excellent site with good practical advice.
If you are unlucky enough to live in one of ththere are a number of steps you can take to minimise damage before the waters invade your property and to speed up repairs once they start to recede. Several insurers have issued advice for those affected; here is a summary of their suggestions.
If you expect to be flooded
Check what kind of damage your buildings and home contents insurance policies will cover and whether you need to update them, particularly if you have new possessions and haven't increased your cover limit recently. Buildings insurance will cover the damage to the structure of your property and home contents insurance will cover your possessions.
Turn off gas, electricity and water at the mains supply.
Disconnect cookers, washing machines, dishwashers and other appliances connected by rigid pipes to gas and water supplies. This will prevent damage to the pipes if the appliance floats or moves during the flooding. Unplug all electrical items and store them upstairs.
Flood water can enter through drains. The easiest way of preventing this is by putting in plugs and weighing them down with sandbags. Disconnect the outflows of washing machines and dishwashers and block them with a cloth or plug to prevent backflow; place a sandbag in the toilet bowl.
Reduce the amount of water entering your property by using sandbags, plywood or metal or plastic sheeting placed on the outside of doors, windows and airbricks. Use silicone sealant to make doors and windows more resistant. Put sealant around the door/window then close and lock. You do not have to seal your home completely. After flooding, remove covers over airbricks as ventilation will aid the drying of your property.
Move furniture and electrical items upstairs and roll up rugs, carpets and curtains for suitable storage (if you are short of time, raise curtains by hanging them over the curtain poles). If furniture is too heavy to move, empty it and move contents upstairs. Raise it on bricks to minimise damage and move it away from walls; this can assist in drying the property later. Your insurer will expect you to minimise any claim in ways such as these.
Floodwater can contaminate foodstuffs and chemicals such as paint, pesticides, cleaning products and garage oils. These materials can also spill or leak into the floodwaters, causing additional clean-up problems. Keep such products upstairs or high up in your garage or shed.
During the flood
Do not touch the electrics.
Leave internal ground floor doors open (they may swell and jam if left closed).
Avoid contact with floodwaters; they may be contaminated with sewage.
Do not wade through deep floodwaters; manhole covers may have lifted, leaving dangerous unseen holes.
Do as instructed by the emergency services - you may have to be evacuated.
Although drivers can claim for damage caused by bad weather, this typically applies to parked vehicles. "Self-inflicted" damage caused by driving through water, thereby flooding the engine or interior, may not be covered. Drivers who chance their arm by driving through floods could face an expensive repair bill.
Coping with the aftermath
Commission immediate emergency pumping/repair work if necessary to protect your property from further damage. This can be undertaken without approval from your insurer. Remember to get receipts and let your insurer know, as it may wish to inspect the damage before permanent repairs are carried out.
Call your insurer as soon as possible and give full details of the damage.
Don't move back into a property that contains standing water - have it pumped out first. Clean and disinfect everything that may have come into contact with the floodwater.
If you haven't already done so, switch off the mains power supply. Don't go into rooms with standing water if the power is still on, and don't use electrical appliances affected by, or in contact with, moisture. Your electrical, gas and water systems should be checked and confirmed safe before they are turned back on. Wash taps and run them for a few minutes before use.
Move anything that is not too badly damaged upstairs or away from flood water where possible.
Fridges and freezers should be cleaned out as soon as possible and any food thrown away. If you have the relevant insurance cover, remember to keep a list of the food items for your claim and, if possible, take photographs.
Once the flood water has begun to recede and if weather permits, open all doors and windows during the day (but take care to ensure your house and valuables are secure).
When you've salvaged as much furniture as possible, start the drying out process by removing a couple of floorboards at each end of affected ground-floor rooms. You may want to borrow or hire dehumidifiers; use one for every two affected rooms and close the windows.
Help plaster to dry by removing wall coverings and skirting boards.
Clear out any mud or silt that has collected in airbricks. This will aid ventilation under floorboards and prevent rot.
Kitchen units are likely to have absorbed water, but may be salvageable. Try to dry them out, and wait for an adjuster to assess the damage.
Do not attempt to redecorate straight away.
Generally, masonry (brickwork or block work) should be largely unaffected by the water if it is allowed to dry out properly. The drying out process may take some time if the masonry has been saturated. As a guide, allow one month for every inch of wall thickness. Check with a decorator or other expert to ensure that the walls and other surfaces are fully dried out and, if necessary, treated to prevent mould.
Preparing for next time
Damage caused by the current floods will inevitably put upward pressure on insurance premiums. But not all insurers will be equally affected, so it will pay homeowners to shop around when it comes to renewing their home insurance.
Individual property owners can do much to increase the resistance of their properties to flood damage. Steps include replacing timber floors with concrete covered with tiles; replacing chipboard or MDF kitchen and bathroom units with plastic equivalents; replacing gypsum plaster with more water-resistant materials such as lime plaster or cement render; moving meters, boilers and electrical points well above likely flood level; and installing one-way valves into drainage pipes to prevent sewage backing up into the house. There are now some good options to fund any balance. For example, the Council of Mortgage Lenders has confirmed that lenders would normally be willing to consider extending loans to cover the additional costs of flood-resilient repairs, provided that the homeowner has sufficient equity and can afford to meet any additional repayments.
Information on current exhbition
SIZE: Cities are increasingly at the centre of global flows of people, capital, culture and information. Over the last 30 years their role as financial command centres has expanded, creating a new type of sprawling, often multi-centred, urban agglomeration.
SPEED: The speed with which many of the world's cities are growing affects their social and physical structure dramatically. The five cities featured in this section - Cairo, Istanbul, London, Los Angeles and Shanghai - are experiencing growth at a different pace, and absorbing it in different manners: some are growing upwards, others are growing outwards.
FORM: This section provides an overview of the distinctly different urban forms of five cities: Istanbul, Johannesburg, London, Mumbai, and Tokyo. Satellite photographs illustrate the diversity and complexity of human impact on these cities, as physically manifest in street widths, block and plot sizes and distribution of open green spaces.
DENSITY: Density – the number of people living in a given area, usually expressed as people per square kilometre – is at the centre of public debate on the future growth of cities. Used as a planning tool, awareness of density can help to curtail over-development and overcrowding, or ensure that scarce urban land is not under-used, especially in areas with good public transport and social amenities. High density does not mean high-rise; large numbers of people can be accommodated in five- or six-storey buildings arranged in a compact and efficient manner, creating congenial places for living.
DIVERSITY n an urban context, diversity - the level of variety within a city - is usually interpreted as its ethnic and racial composition. But diversity has a much broader range of indicators: the spread of ages and incomes, education levels, the range of employment sectors, and people born in the city versus newcomers.
According to the Energy Saving Trust, the average British household emits around six tonnes of CO2 and spends around £870 on power and fuel a year, but both figures can be massively cut with a few simple steps.
1 Change your light bulbs to eco ones replace your home’s conventional light bulbs with energy-saving ones. The latter used to be really expensive but prices have dropped dramatically and they come in all shapes and sizes, as well as different wattages and hues. Low-energy light bulbs last up to 12 times longer than conventional ones, and just one bulb will save you around £9 and 40kg of CO2 emissions a year. Incredibly, if every household in the UK had just three of these eco bulbs, we’d save the equivalent of the annual output of a power station.
2 Insulate Insulate your loft, walls and hot water cylinder. British homes lose enough heat through their walls and roofs to heat approximately 3,000,000 homes every year. Almost a quarter of heat loss is through the roof, but adequate loft insulation will save you around £180-£220 and one tonne of CO2 a year. Similarly, cavity wall insulation will cut your heat loss by approximately 60 per cent, saving you around £130-£160 and one tonne of CO2 a year.
3 Change your boiler All new boilers (with a few exceptions) have to be energy-efficient condensing ones, which retain heat from the gasses usually expelled down the flue. Have one of these fitted (by a CORGI installer) and you’ll cut your heating bills by around a third and emit one tonne less of CO2 a year.
4 Recycle Shockingly, Britain’s recycling record is one of the worst in Europe, according to the most recent comparable figures, with only Greece and Portugal recycling less. Of the 600kg of waste generated by each of us in Briton a year, 74 per cent goes to landfill, 8 per cent is incinerated and just 18 per cent is recycled or composted, compared to 65 per cent in the Netherlands and 58 per cent in Germany. Buying recycled goods (something many of us forget but also vitally important) and increasing your home recycling by just 10 per cent will save around 90kg of CO2 a year.
5 Draught proof and/or double glaze your windows Single-glazed windows and poorly insulated frames can result in a fifth of all heat loss. Double glazing can reduce this loss by 50 per cent and save you around £80-£100 and 570kg of CO2 a year. If you can’t afford double glazing (or secondary double glazing), invest in draught excluders for your windows and doors (both internal and external) instead. Draught proofing your doors and windows will save you around £20 and 140kg of CO2 a year.
6 Compost While the UK is only, of course, recycling and composting about 18 per cent of its waste, a third or more of household waste can actually be composted. As well as green and food waste, you can compost all kinds of things you might not consider suitable, including kitchen roll, shredded paper, cardboard and vacuum cleaner bags. If you don’t have outside space, you can get compact compost bins and sprinkle on a Japanese substance called Bokashi, which breaks the matter down quickly and should take care of any unpleasant odours. You could even have a communal compost bin if you live in a block of flats. Other benefits of composting include fewer bin bags to contend with when putting out the rubbish, knowing you’re contributing less to landfill and having an end product that will enrich your garden and house plants.
7 Full loads only Never put a washing machine or dishwasher on without it being full, unless you have an economy or half-load programme, because you’re wasting water as well as energy. Wash your clothes at 30Þ and you’ll save around 40 per cent of the energy your washing machine uses. Energy-sapping tumble drying should also be ditched in favour of drying clothes outside, on radiators and clotheshorses or in the airing cupboard. Tumble driers are one of the worst offenders in the home for CO2 emissions: a year of not using yours will save you around £75 and 635kg of CO2.
8 Only boil enough water for your needs It’s all too easy to turn the tap on and fill the kettle up without considering how much water you actually need, but again you’re wasting both water and electricity. Only boil enough water for your needs – at home and work – and you’ll make big savings. It’s estimated that if all of us stopped “filling” the kettle, enough energy would be saved to power between 50 and 75 per cent of the UK’s street lights.
9 Conserve energy when cooking Chop food into small pieces when cooking, as it will cook quicker and use less energy. It’s also important to boil water for cooking in the kettle and then transfer it to the hob, to only boil enough to just cover the food, to put the saucepan lid on and to ensure the pan’s the right size for the burner or ring you’re using, otherwise energy will be lost around the sides.
10 Don’t leave appliances on standby That little coloured standby light uses 10-60 per cent of the energy needed to power the appliance when in use, so always switch it off at the socket. Alternatively, invest in a Bye Bye Standby kit, which cuts power to appliances left on standby so you don’t even need to think about it. Eight per cent of UK households’ energy, or four million tonnes of CO2 annually, is wasted by appliances left on standby. Stamp out standby and unplug chargers and you could save as much as £130 and 560kg of CO2 a year. Another useful gadget is the Electrisave, which shows how much electricity you’re using so you can identify the most power-hungry appliances in your home.
Climate change has become a major security issue that could lead to "a world going up in flames", the United Nations' top environment official has warned. From rising sea levels in the Indian Ocean to the increasing spread of desert in Africa's Sahel region, global warming will cause new wars across the world, said Achim Steiner, executive director of the UN Environment Programme (UNEP).
"People are being pushed into other people's terrain by the changing climate and it is leading to conflict," he said. "Societies are not prepared for the scale and the speed with which they will have to decide what they will do with people."
The world was already experiencing its first war partly caused by climate change, he said. Dramatic changes to the environment in the Darfur region of Sudan helped lay the ground for today's conflict which has displaced more than 2.5 million people and killed at least 200,000.
A report to be published by UNEP tomorrow will make a direct link between climate change and the Darfur conflict. "It will be one of the most significant documents in terms of linking environment change and conflict," Mr Steiner said. "It will say that climate change is now a key dimension that must be considered in conflict issues."
The roots of the four-year conflict can be found in the devastating drought that swept Sudan and the Horn of Africa in the 1980s, the report will say. Since then, rainfall in Sudan has fallen by 40 per cent, a result, claim scientists, of global warming. Farmers began to fence off land to which nomads once had access. Clashes over shrinking resources between nomads, who tend to be Arab, and the mainly African farmers became widespread.
The current crisis was sparked by a rebellion launched by three Darfuri tribes, and a ferocious counter-insurgency unleashed by Khartoum, but the dramatic changes to Darfur's ecology appear to have been a contributing factor. "What we see in Darfur is an environmental change phenomenon unfolding that puts pressure on local communities," Mr Steiner said. "Combine that with potential tensions and you very quickly get a potent mix within which increased pressure can result in conflict. The situation that emerged in Darfur will emerge in other parts of the world." He warned of a "world going up in flames" if countries did not "wake up", adding: "It is a major security issue that affects the whole geopolitical dynamics that we have today."
Earlier this year Britain used its presidency of the UN Security Council to lead its first debate on climate change and conflict. "What makes wars start?" asked the Foreign Secretary, Margaret Beckett. "Fights over water. Changing patterns of rainfall. Fights over food production, land use. There are few greater potential threats... to peace and security itself."
The two major areas of potential conflict, Mr Steiner said, are the Sahel region and east Asia. "In the next 35 years most of the glaciers in the Himalayas will... disappear. You are talking of 500 million people being affected directly and another 250 million people affected downstream." Rising sea levels off the coast of Bangladesh are another potential area for conflict, he said: "India has already started building a wall to stop Bangladeshis coming across. The predicted half-a-metre sea level rise means 34 million people not being able to stay where they are now. Where will they go? They will break through the boundaries."
But Africa is likely to suffer most. Rising sea levels could destroy up to 30 per cent of the continent's coastline, while between 25 and 40 per cent of Africa's natural habitats could be lost by 2085. Conflicts caused by a scarcity of resources are already brewing across Africa. In Ghana clashes between farmers and Fulani herders have become more widespread as resources have become increasingly scarce. In the Mount Elgon region of Kenya more than 40,000 people have been displaced as different tribes fought over access to land.
Climate change will also cause problems post-conflict. According to the UNEP report on Darfur, the majority of those displaced by the conflict will never be able to return to their homes. "We have have moved beyond a point of return," Mr Steiner said.
Migrant workers have boosted the UK economy, with their influx not having a negative effect on employment or wage levels, the TUC has argued.Foreign workers made a positive net economic contribution, it said, with their share of tax paid exceeding the cost of supplying public services.
The Problem By the year 2050, nearly 80% of the earth's population will reside in urban centers. Applying the most conservative estimates to current demographic trends, the human population will increase by about 3 billion people during the interim. An estimated 109 hectares of new land (about 20% more land than is represented by the country of Brazil) will be needed to grow enough food to feed them, if traditional farming practices continue as they are practiced today. At present, throughout the world, over 80% of the land that is suitable for raising crops is in use (sources: FAO and NASA). Historically, some 15% of that has been laid waste by poor management practices. What can be done to avoid this impending disaster?
A Potential Solution: farm vertically The concept of indoor farming is not new, since hothouse production of tomatoes, a wide variety of herbs, and other produce has been in vogue for some time. What is new is the urgent need to scale up this technology to accommodate another 3 billion people. An entirely new approach to indoor farming must be invented, employing cutting edge technologies. The Vertical Farm must be efficient (cheap to construct and safe to operate). Vertical farms, many stories high, will be situated in the heart of the world's urban centers. If successfully implemented, they offer the promise of urban renewal, sustainable production of a safe and varied food supply (year-round crop production), and the eventual repair of ecosystems that have been sacrificed for horizontal farming.
