Even before the current war, Yemen was the poorest country in the Middle East. Chronic poverty has been aggravated by conflict, weather and long-term instability. More than ten million people have insufficient food and two million have been displaced within the country. Bombing and fighting continues in many places and there are few aid agencies on the ground with too little money. Too many of those that are there have been holed up in the capital.
When MPs debate the UK's aid target today, I hope we are presented with a full picture of the pros and cons of aid spending. I'm proud that Britain hasn't turned its back on the world's poorest - the fact that the rest of the world has not yet followed suit is a reason to carry on, not retrace our steps. We can and must continue to do better, but there should be no doubt that British aid is transforming the lives of millions of the most vulnerable people on the planet.
As duty bearers of human rights, it is the responsibility of states to ensure that their citizens are able to realise their rights. The High Level Panel's recommendations are set to come out in June and will be addressed to heads of state. It is yet to be known whether these recommendations will have an accountability mechanism attached to them so it may well fall to civil society to hold governments to account.
Here we are watching rich countries debating yet again whether Syrian refugees should be allowed in or not, whether they pose a security threat or are linked to terrorist groups. At Oxfam, we've been calling for the resettlement of 10 per cent of the most vulnerable five million registered Syrian refugees...
Most of us remember the image of thousands of Ethiopians starving during the famine of 1984/85, the luckier ones seemingly fed only by the power of the Western media to incite compassion and belated action from international agencies. On a recent visit to the country, I heard how the weather conditions now are as bad as during that terrible disaster...
What sort of system have we created that relentlessly siphons wealth from the poor to the richest 1%, and in the process deprives humanity of the resources that could bring happiness, contentment and joy to billions of people? When, oh when, will world leaders take concrete steps to remedy this injustice and unfairness?
Inequality has been shown to impact on the durability of economic growth and increases the chances of future financial shocks; it undermines social cohesion and equality for women; and it increases political instability. In a surprising echo to Aicha's words, the self-proclaimed zillionaire Nick Hanauer wrote in 2014 that "if we don't do something to fix the glaring inequities in this economy, the pitchforks are going to come for us"... Economic and policy changes in recent decades - including deregulation, privatisation, financial secrecy and globalisation, especially of finance - have supercharged the age-old ability of the rich and powerful to use their position to further concentrate their wealth.
As Mark Carney and others have said, greater fairness is needed, because without it, the social contract that binds us together is weakened. When people feel that the playing field is far from level, that the rules are rigged by those with power and influence to work against them and their children, society begins to feel the strain.
The Government yesterday announced its final pre-election budget and, as expected, there was quite a bit in there on tax avoidance. That's hardly surprising - we know that there is overwhelming public support for action on tax dodging. Unfortunately none of the big parties have yet gone far enough - and yesterday's budget announcements don't change that.
Oxfam is in Liberia and Sierra Leone for the long haul. We're continuing to work with communities to build understanding of Ebola treatment and how to stay healthy, providing financial support to help families get back on their feet, and helping them guard against infectious diseases by equipping schools and clinics with clean water and sanitation.
