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.

I call for the need of world leaders to address climate change and reduce the increasing risk of disasters- and world leaders must include mayors, townships and community leaders.

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.

Achieving gender equality requires the engagement of women and men, girls and boys. It is everyones responsibility.

Climate change does not respect border; it does not respect who you are - rich and poor, small and big. Therefore, this is what we call global challenges, which require global solidarity.

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.

Women must be full partners in development, so they can lift themselves and their communities out of poverty.
