I stand before you and the world humbled by this recognition and uplifted by the honour of being the 2004 Nobel Peace Laureate.

As the first African woman to receive this prize, I accept it on behalf of the people of Kenya and Africa, and indeed the world. I am especially mindful of women and the girl child. I hope it will encourage them to raise their voices and take more space for leadership. I know the honour also gives a deep sense of pride to our men, both old and young. As a mother, I appreciate the inspiration this brings to the youth and urge them to use it to pursue their dreams.

Although this prize comes to me, it acknowledges the work of countless individuals and groups across the globe.

This honour is also for my family, friends, partners and supporters throughout the world. I am also grateful to the people of Kenya—who remained stubbornly hopeful that democracy could be realized and their environment managed sustainably.

I am immensely privileged to join my fellow African Peace laureates, Presidents Nelson Mandela and F.W. de Klerk, Archbishop Desmond Tutu, the late Chief Albert Luthuli, the late President Anwar el-Sadat and the UN Secretary General, Kofi Annan.

In this year's prize, the Norwegian Nobel Committee has placed the critical issue of environment and its linkage to democracy and peace before the world.

My inspiration partly comes from my childhood experience and observations of Nature in rural Kenya. It has been influenced and nurtured by the formal education I was privileged to receive in Kenya, the United States and Germany. As I was growing up, I witnessed forests being cleared and replaced by commercial plantations, which destroyed local biodiversity and the capacity of the forests to conserve water.

In 1977, when we started the Green Belt Movement, I was partly responding to needs identified by rural women, namely lack of firewood, clean drinking water, balanced diets, shelter and income.

Throughout Africa, women are the primary caretakers, holding significant responsibility for tilling the land and feeding their families. As a result, they are often the first to become aware of environmental damage as resources become scarce and incapable of sustaining their families.

The women we worked with recounted that unlike in the past, they were unable to meet their basic needs. This was due to the degradation of their immediate environment as well as the introduction of commercial farming, which replaced the growing of household food crops.

Tree planting became a natural choice to address some of the initial basic needs identified by women.

So, together, we have planted over 30 million trees that provide fuel, food, shelter, and income to support their children's education and household needs. The activity also creates employment and improves soils and watersheds. Through their involvement, women gain some degree of power over their lives, especially their social and economic position and relevance in the family. This work continues.

Initially, the work was difficult because historically our people have been persuaded to believe that because they are poor, they lack not only capital, but also knowledge and skills to address their challenges.

In order to assist communities to understand these linkages, we developed a citizen education program, during which people identify their problems, the causes and possible solutions. They then make connections between their own personal actions and the problems they witness in the environment and in society. They learn that our world is confronted with a litany of woes: corruption, violence against women and children, disruption and breakdown of families, and disintegration of cultures and communities. They also identify the abuse of drugs and chemical substances, especially among young people. There are also devastating diseases that are defying cures or occurring in epidemic proportions. Of particular concern are HIV/AIDS, malaria and diseases associated with malnutrition.

Through the Green Belt Movement, thousands of ordinary citizens were mobilized and empowered to take action and effect change. They learned to overcome fear and a sense of helplessness and moved to defend democratic rights.

As we progressively understood the causes of environmental degradation, we saw the need for good governance. Indeed, the state of any county's environment is a reflection of the kind of governance in place, and without good governance there can be no peace. Many countries, which have poor governance systems, are also likely to have conflicts and poor laws protecting the environment.

In 2002, the courage, resilience, patience and commitment of members of the Green Belt Movement, other civil society organizations, and the Kenyan public culminated in the peaceful transition to a democratic government and laid the foundation for a more stable society.

The Norwegian Nobel Committee has challenged the world to broaden the understanding of peace: there can be no peace without equitable development; and there can be no development without sustainable management of the environment in a democratic and peaceful space. This shift is an idea whose time has come.

I call on leaders, especially from Africa, to expand democratic space and build fair and just societies that allow the creativity and energy of their citizens to flourish.

I would also like to appeal for the freedom of my fellow laureate Aung San Suu Kyi so that she can continue her work for peace and democracy for the people of Burma and the world at large.
