Hidden hunger is caused by a lack of nutritious food and results in insufficient essential vitamins and minerals being absorbed into the body. It can have long-term, irreversible health effects as well as socioeconomic consequences that can erode a person's well-being and development. By affecting people's productivity, it can also take a toll on countries' economies...
I believe that if children are to enjoy their right to an education they must be taught by teachers who are properly trained and supported. There is a pressing need to consider how best to train teachers - both new teachers and up-skilling the large numbers of currently unqualified and under-qualified teachers through in-service training.
Financial inclusion has become a buzzword for governments intent on tackling poverty and inequality among their citizens. India's Prime Minister Modi just announced that he wants to end 'financial untouchability' with an ambitious target to provide most households with a bank account in a matter of months.
Of all the threats to life that people in the developing world face, it is astonishing that the simple act of cooking is one of the greatest dangers of them all. And the scale of the tragedy is enormous; nearly three billion people in the developing world cook food and heat their homes with firewood or charcoal on traditional cookstoves or open fires.
After two years of declining world aid, last Tuesday, the Organization for Economic Co-operation and Development (OECD) released new figures that demonstrated that aid had reached a record high in 2013 and increased by over 6.1%. In the face of what appears to be a gratifying headline, beneath the surface lies a far more depressing state of affairs.
The world over, we are seeing ever more cases of extreme weather, from the recent floods in the UK to wild fires in Australia. With each incident comes the familiar assurances that - this time - the necessary action will be taken to make sure there is no repeat. The reality is we have no choice, as every country faces the fact that climate change - and its impact on the weather - is no longer a distant prediction, but a daily reality. And for the poorest people on the planet, the need to change is not just a matter of saving money, but saving lives.
When Antony Jenkins took the helm at Barclays he promised to clean up a bank that had been badly scarred by a seemingly relentless stream of scandals. To re-enforce the point he sent an email to his 140,000 staff saying that he wanted to bring new ethical standards to Barclays. Those who didn't want to sign up to them were told they should leave.
When I launched Live Below the Line in the UK in 2012 I didn't think doing the challenge was going to be difficult at all. I thought those who screwed up their faces when I proposed the challenge were simply lazy. I remember being a student - the Smart Price pies, Pot Noodles and spaghetti shapes. Living on so little for over three years, how hard could living on £1 a day for five days really be?
I wonder if I can persuade you that, despite the utter horror of this week's headlines from Syria, we are lucky to live in an era of unprecedented human progress. Yes, I'm going to try to convince you that for more people, in more places, the world has more to offer now than at any time in the history of our species.
The Bill would massively restrict the amount that campaigning charities and other UK community groups could spend in the year before an election whilst silencing us with unnecessary red tape. And if you're wondering why US-style funding systems don't yet exist in the UK, it's because they're already illegal.
The biggest tragedy of all is, if we're lucky enough to survive until we're old, grey and wrinkled, and our grandchildren ask us what we gave to the world we lived in, we are only able to say that we took more than we gave. For the man who dies without giving more than he has taken can take no triumph from his life.
You don't have to be a Marxist to feel a sense of outrage at these statistics. I trust that most of us with an ounce of sympathy for the suffering of fellow human beings would sense that the global economic system that engineers such disparity in the way people live is dysfunctional and requires serious reforms.
Kanchi Tamang is a waste-picker in Nepal. A mother and a grandmother, she works long hours in unsafe and unclean conditions for a pittance. After contracting Hepatitis C, then developing painful gallstones, she faces the prospect of medical treatment that will require her to be absent from work and hospital bills that, together with the loss of work income, might mean that she loses her home and cannot support her family. Yet if she does not receive treatment, she might lose her life, not just her livelihood.
