To achieve a Green Revolution, African farmers, must have access to land and security of tenure. They also need access to markets, technology and improved infrastructure.

Climate change has happened because of human behaviour, therefore it’s only natural it should be us, human beings, to address this issue. It may not be too late if we take decisive actions today.

As the young leaders of tomorrow, you have the passion and energy and commitment to make a difference. What I'd like to really urge you do is to have a global vision. Go beyond your country; go beyond your national boundaries

Our world is one of terrible contradictions. Plenty of food, but one billion people go hungry. Lavish lifestyles for a few, but poverty for too many others. Huge advances in medicine while mothers die every day in childbirth, and children die every day from drinking dirty water. Billions spent on weapons to kill people instead of keeping them safe.

Universal ratification of the Optional Protocol on the Involvement of Children in Armed Conflict will establish an international moral consensus that no child should take part in hostilities or be involuntarily recruited and that former child soldiers should be assisted by their governments after a life of violence and distress.

Let us acknowledge and celebrate what youth can do to build a safer, more just world. Let us strengthen our efforts to include young people in policies, programmes and decision-making processes that benefit their futures and ours.

You have to work and think about how we can make this world a better place for all. This is what I'd really like to ask our young leaders. We will try as leaders of today to minimise the problems which we will hand over to you. But it is to you. You have to take ownership and leadership of tomorrow. For that to be possible, you have to strengthen your capacity and widen your vision as a global citizen.
