Saving our planet, lifting people out of poverty, advancing economic growth... these are one and the same fight. We must connect the dots between climate change, water scarcity, energy shortages, global health, food security and women's empowerment. Solutions to one problem must be solutions for all.

We hold the future in our hands, together, we must ensure that our grandchildren will not have to ask why we failed to do the right thing, and let them suffer the consequences.

One of my earliest memories is walking up a muddy road into the mountains. It was raining. Behind me, my village was burning. When there was school, it was under a tree. Then the United Nations came. They fed me, my family, my community.

Climate change, demographics, water, food, energy, global health, women's empowerment - these issues are all intertwined. We cannot look at one strand in isolation. Instead, we must examine how these strands are woven together.

There can be no solution to the challenge of climate change that is not global. But if we can come together in partnership, we can transform today's challenge into tomorrow's opportunity - an opportunity for green growth and sustainable prosperity... we also need a strong bottom-up push from academics and opinion-shapers such as you. Universities such as yours are founts of ideas and innovation. They are furnaces of innovation and entrepreneurship. So, send forth this word.

A deal must include an equitable global governance structure. All countries must have a voice in how resources are deployed and managed.

Countries with more gender equality have better economic growth. Companies with more women leaders perform better. Peace agreements that include women are more durable. Parliaments with more women enact more legislation on key social issues such as health, education, anti-discrimination and child support. The evidence is clear: equality for women means progress for all.
