Today, hundreds of people are due to hold a march in the Nigerian capital of Abuja to demand the government do more to find the girls. As they march, we must all raise our voices, so that the Chibok girls are brought home safely, and all girls have the opportunity to go to school without the threat of violence.
Since the time when the girls were taken from their school by armed militiamen, the impact of the conflict on children has grown dramatically. Over the past year, 44 children have been used as suicide bombers. In fact, the number of children used in suicide attacks has increased ten-fold over the last year and over 75% of the children involved in the attacks are girls. Nearly one out of every five suicide bombers is a child.
Many of us reading this are living in a country where there is freedom of the press and free speech. Two basic rights which, tragically, have been denied to millions around the world. So if media houses have this freedom, let's see them use it responsibly, without relying on a trending hashtag, or a sprinkle of stardust to make it part of their agenda. Let's not wait for #Darfur or #Dalori to trend before we hear stories like these on our news channels.
For decades, Mercy Corps has worked with refugee and displaced populations, we know that building walls does not work. Europe's Schengen Agreement must remain in place and we must avoid the simplistic pretence that fences can be placed at our borders to preserve our economic well-being and security.
Schengen in on life support and West African manufacturers should pay close attention. They are already convinced they won't be able to compete with the cheaper, better quality imports, which will be the inevitable result of a forthcoming EU/Africa free trade agreement. For most, exporting to Europe is a distant dream anyway. Increased border restrictions will make it even more unlikely.
The hard-won battle to eradicate polio once and for all is within our grasp but we can't relax yet. We must, maintain and accelerate our efforts. So it is heartening to see Commonwealth countries, including the UK, coming together this weekend at the Commonwealth Heads of Government meeting in Malta to review the results achieved to date and call for renewed global support.
A World Bank report published last week found that in the past 25 years, over a hundred countries have enacted laws on domestic violence though many have not. The authors attribute much of this progress to international instruments and agreements. In reality, it is the work of local women's rights organisations that makes the most difference and that's why they need our support.
The importance that the tech sector might hold for economic development and diversification is recognised, and state investment has been forthcoming in various ways. In some cases, funds have been put forward for the building of 'incubation' centres and meeting places as was the case for Nigeria's Information Technology Entrepreneurship Accelerator in Lagos.
The measure of success in Northern Nigeria is whether civilians feel free from fear. Nigeria's sovereign government, with international partners lending their expertise, should be able not simply to clear the battlefield, but to satisfy the reasonable aspirations of the people to a secure and prosperous future. That could be a lesson for the rest of the world to learn.
