show 6m documents went to the bbc show 47% rise in psychiatric attendances at accident and emergency department in england over the past four years. and a look at the markets, this is how the ftse ended the day in london and the dax in frankfurt. the dow and the dax in frankfurt. the dow and nasdaq also doing well in the united states. supermarket chain morrisons has recorded a strong period, with like—for—like sales rising by almost 396 of top mince pies baked in store, to show stopping turkey we like to treat ourselves at christmas. at morrisons, they lured shoppers in and they served up some great results. christmas, morrisons makes it.

i think it is a remarkable performance. 2.9% growth on last year in this marketplace, the team are really to be congratulated at morrisons and they delivered that through improving customer service and also making products more available to the customers when they need to buy them. no doubt about it, morrisons was one of the big winners this christmas. butjudging by new figures out today, business was good for the supermarkets in general. because christmas fell on a sunday, we had a whole week to shop and it was huge. round it all up, we spent £a80 million more on groceries than we did last year for the 12 weeks to the end of december. that's growth of nearly 2%. but for the first time in two years, prices rose by 0.2%. a sign of things to come. food sales helped deliver a solid december for the retail sector overall. it was a goodish end to a bit of a roller—coaster year. retail sales across the whole of 2016 grew more slowly than they had done in the previous year. that raises more questions in the minds of both consumers and retailers as to what the outlook for 2017 might be.

shoppers left it later than ever this year, but we did spend. the question is, will we continue to do so in 2017? emma simpspon, bbc news. the brazilian government is planning to to build dozens of dams in the amazon region. it says it will boost the economy and provide clean energy. but critics say it will also mean deforestation, and the end of traditional life for many of brazil's indigenous tribe, as wyre davies now reports. from the heart of the planet's greatest rainforest emerges one of the world's biggest civil engineering projects. a monolithic monument to progress. the belo monte dam is brazil's answer to its growing energy needs. mired in controversy and allegations of corruption, the $18 billion dam partially blocks the xingu, a major amazon tributary, and has flooded thousands of acres of rainforest. there's a human cost too.

the local fishing industry has been decimated, and thousands of riverside dwellers have lost their land and their livelihoods. forced into a completely alien, urban environment. we get angry, sastuma, showing us his now worthless fishing licence. we see these corporations making millions from what used to be ours, he says, and we can't even use the river any more. building the dam brought hundreds ofjobs to the riverside town of altamira. but it also led to increasing deforestation and the permanent loss of many low—lying islands. supporters of hydropower admits mistakes were made. but say the rivers and their energy are there to be harnessed for the greater good of brazil. i would definitely defend

the presence of hydro as a key technology in our portfolio of technologies. in the developed part of the world, almost 70% of the hydro potential has already been explored. in brazil, almost 70% of our hydro potential has not been explored yet. brazil says it wants to build at least 50 hydroelectric dams across the amazon. the government says it is clean, sustainable energy. but the impact of so many of these structures on the world greatest river system, its environment and its people, will be immense. next in line for development, the tapajos, described as the most beautiful river in the amazon region, and home to these indigenous people. a plan to build several dams along its length will transform this wide, shallow river into a navigable water highway. it would flood forests and islands used by the people for centuries. tribal chiefs say they will resist

any attempts to build dams on the river. translation: the government always comes here with its lies. there's not one place where a dam has been built that has turned out good for locals and for our tribes. there is only misery and complaints. these tattooed warriors of the amazon are taking on powerful business and political interests. they want to weaken environmental legislation and fast track the construction of hydro—electric dams. clean energy and the promise ofjobs versus the rights of indigenous tribes. and whether to exploit or protect this fragile ecosystem. for the first time ever, researchers have filmed chimpanzees making and using tools to get access to water that no other animal can reach. the study of a critically endangered population of chimpanzees in the ivory coast discovered them

using tree branches to collect water. victoria gill reports. a life—saving skill. a mother and baby in ivory coast's comoe national park show some unique behaviour. it's the dry season, so to reach a water supply hidden deep within these tree holes, they are making and using tools. it's just another insight into the remarkable behaviour of our closest primate cousins. if you think they've got 90—95% the same dna as humans, they are very intelligent animals. we've seen it, working at chester zoo with these animals, the kind of things they can do. the different cultures of chimpanzees have learnt different tool use. so it's certainly not new to find chimpanzees using tools. the animals are already known to use sticks to fish for termites and to dip into beehives for honey, but the researchers were particularly impressed by how well crafted these drinking tools were. chimps selected and stripped long

thin sticks and chewed the ends into very water—absorbent brushes. and for captive breeding programmes like this one, zoos have to understand these natural behaviours to keep the animals as mentally stimulated as possible. we give them small sticks. and then we give them an area where they keep honey, ready brek, that kind of thing. and they have to use their sticks, make them into a certain way so they can put the stick in the hole and get the food out. encouraging natural behaviours. it's all gone very quiet here at chester zoo because it's feeding time for the chimpanzees, and these are actually western chimpanzees, the same subspecies that was looked at in this piece of research. nimble fingered, very clever, toolmaking and tool—using, but sadly, critically endangered primates. in the wild, the population of these great apes continues to decline, largely because of poaching and the destruction of their forest habitat. findings like this showjust how

much more we have to learn about chimpanzee culture. tonight, president obama will deliver his farewell address in chicago. the city is where he claimed victory eight years ago in an historic election that put the first african american in the white house. mr obama's time as us president will come to an end on the 20th of january. let's join gary 0'donoghue now who is in chicago ahead of president 0bama's farewell address tonight .. it is the windy city! what are we expecting from the president in these final remarks? it is a valedictory, the whole story, the whole 0bama odyssey began here on the south side of chicago as a

community organiser. he became a state senator and then senator in the us senate itself. i think it will be a kind of book end. he will try to talk i think about some of the achievements of his eight years. the financial crisis, emerging from that, saving the auto industry, killing 0sama bin ladin, creating 15 millionjobs. all these kinds of things. i think also and he has already written what you might call an exit memo from office and that spoke of some of the disappointments as well. the failure to pass conference of immigration control, failure to pass any kind of gun control legislation. so i think we will get something of a shopping list of what has and has not happened. but i think the interesting thing will be the extent to which she tries to warn about the future, one about the consequences

of unthinking things like his totemic health reforms, his health ca re totemic health reforms, his health care legislation. because clearly that in particular is right at the top of the republican agenda and without much idea of what they are going to put in its place. i think he will warn about those 20 million americans who might end up with no health insurance soon. americans who might end up with no health insurance soonlj americans who might end up with no health insurance soon. i read that donald trump are saying he will not accept any delay of more than a few weeks in repealing 0bamacare, in getting rid of it. are we likely to see a president who is going to make about 300 grand on the speaking circuit, playing golf, orwill about 300 grand on the speaking circuit, playing golf, or will he be an activist and former president which would go against the grain given so many of his signature policies are headed for the dustbin?

0ne prediction that i will make with 100% certainty, and most are my predictions in the past 12 or 18 months have been absolutely useless! but this i will make committee will continue to play golf. and quite a lot of it. that is one thing we can be clear about. the interesting thing about the rest of it, he talked about staying on the field in terms of politics. i think there is an interesting problem for the democratic party, they do not have the next generation of leaders, really, prominently nationwide people to take over the mantle. i think he is aware of that and i think he is aware of that and i think that he will be someone who will be vocal about the consequences of changing some of these policies that he fought long and hard for. i do not think that he is going to disappear, i could be wrong, into

the speaking circuit. i think he feels he has a responsibility. after all not so long ago he said he thought he could have won a third term if he had been allowed to run. stay on your feet there, in the windy city! time for a look at the weather now. it has been pretty windy here and that continues over the next few days. behind this weather front it is turning very blustery over the next few hours. and that will bring some rain into scotland and northern ireland. then the wind picks up, reaching gale force in the north and west. the showers across scotland turning increasingly wintry overnight. and the wind really is a key feature through the middle of the week. strong and gusty wind, and

travel disruption certainly possible across the northern part of the uk. the wind will be howling its way through the central lowlands from west to east. further south not too many showers through the morning but quite blustery. and the strongest wind further west. bear that in mind. and some showers across wales and the south—west of england but generally in the southern half of england, not many showers tomorrow but wendy. 0nto the afternoon, some snow just creeping down but wendy. 0nto the afternoon, some snowjust creeping down the mountains. it stays windy into thursday, still blowing a gale for some and snow showers getting down to low levels in scotland and also northern ireland and the north of england. quite cold by the end of the night, perhaps some icy thatch

—— icy patches and frost. the weather front, there is —— icy patches and frost. the weatherfront, there is some —— icy patches and frost. the weather front, there is some doubt as to how north it could go. but how much cold air will get into the mix as well and consequently how much snow. we are likely to see some snow at least across higher ground but most of it will be rain. further north it is windy with further wintry showers and it feels quite cold. two or three degrees on the face of it but feeling like two or three degrees below zero. then we have another area of low pressure on friday, generally speaking a lot of cold airand friday, generally speaking a lot of cold air and windy weather for the end of the week. that is it for now. this is bbc news.
