Science, Policy, and Advocacy on Population and the Environment

About Us

The Center for Environment and Population's (CEP) mission is to achieve a healthy balance between people and the environment, through research, policy and advocacy work. This is done through a focus on population and environmental linkages, reproductive health and rights, women/girls empowerment, and sustainable development.

CEP is a project of the Tides Center. It was founded in 1999 as an offshoot of a UNFPA and MacArthur Foundation-sponsored American Association for the Advancement of Science (AAAS) program to implement the UN International Conference on Population and Development (ICPD) Programme of Action, and, to ensure that the best available science-based knowledge on key human population and environmental issues and linkages is actively integrated into policies, advocacy and action at the US grassroots/community to national, and international levels.

The environmental impacts of human population are occurring at rates, scales, and types never before experienced. Reproductive health and rights are being challenged in the US domestically and at the global level. These two dynamics are fundamentally linked and at the core of US and global efforts to achieve a balance between people and the environment which supports life. In addition, women and girls are uniquely involved and affected by these issues.

The analyses of these issues - particularly the most current scientific thinking and emerging trends in the field - are rarely fully reflected in public policies, outreach, and advocacy.  Scientists and other leading experts seldom have the opportunity to communicate their research or knowledge broadly, so decision makers and the general public do not often benefit from their findings.

In addition, core issues such as reproductive health and rights, or youth and/or women/girl-centered approaches, are often under-represented in efforts to achieve a long-term sustainable balance between people and the natural environment.

The Center uniquely fills this gap by partnering with leading organizations such as the Planned Parenthood Federation of America, Woodrow Wilson Center, Population Action International, Advocates for Youth, Climate Wise Women, Population Reference Bureau, UNFPA, League of Women Voters, Sierra Club, Yale University, and others (see Partners), to form a critical triangle from science, to policy, to advocacy and action on the issues.

Through award-winning, groundbreaking resource materials and strategically planned activities, the Center, with its partners, strengthens the scientific basis of policies and advocacy in order to move the issues forward. CEP does this through its three program areas: population and environment linkages; reproductive health and rights, and; women/girls empowerment - in the US domestically and some cases, globally.

CEP undertakes its own program activities as well as consultancies on the issues. For an organizational chart, click here. For additional information see CEP Programs and Services.
