The Great Famine is a period of our history that we need to know in great detail in order to understand its continuing impact on us as a people. Its causes were complex. We can't apportion blame simplistically but rather [must] understand that blame has to be shared in different areas and levels of society. It was the very poorest of the poor, the small tenants and cottiers, who really suffered. Others were less affected. But most of all I welcomed the commemoration because it was a moment to look into our past and realize the courage and resilience of those who survived.

I'm struck by how very few people outside a rarefied world of true believers understand what you mean when you say human rights - that includes development experts and economists who are very keen to implement the UN Millennium Development Goals. They've told me quite frankly, that they don't know exactly what a human rights approach is.

Every government has signed up to a voluntary legal commitment under at least one of the international covenants and conventions based on the Universal Declaration of Human Rights. But who is holding them to account? Our mission is to make it known that these conventions are good tools for civil society to hold their local authority, their government and businesses accountable.

The structures of the WTO need to be reformed to increase participation. There must be a greater sense of shared ownership of the substance of the trade negotiation agenda. Decisions about issues to be negotiated, and in which sequence they should be taken, should rest with all WTO members, not only the most powerful.

It is a great problem for the true international agenda of human rights that the United States, uniquely among industrialised countries, has not ratified three main instruments, has not ratified the Covenant on Economic, Social and Cultural Rights, or the Convention on the Rights of the Child, or the Convention for the Elimination of Discrimination Against Women, and we could have so much richer a debate and dialogue on international human rights standards if the superpower would sign up to the agenda.

In general, I don't think that economic, social and cultural rights are primarily a matter of going to court. They are most useful today as commitments which can help ensure effective and equitable policy-making at every level.

Human rights are inscribed in the hearts of people; they were there long before lawmakers drafted their first proclamation.
