Who we are

Yarrow Global Consulting gGmbH is a feminist non-profit founded in 2019 that focuses on the intersection of health, gender and the environment. Through qualitative research and evaluation, consultancy work and policy analysis we contribute to dismantling unequal power structures and driving sustainable change at organizational and policy levels. We work with an international network of professionals from the areas of global health and wellbeing, gender research and feminist thought, and environment and climate change.

Mission Statement


Our mission is to improve the health and wellbeing of communities by facilitating dialogue, building capacity and disruptive change. We work with civil society groups, especially those lead by women or other historically excluded groups, policy makers as well as public and private enterprises to develop more inclusive, equal decision-making processes.


Our goal is to contribute to a feminist and decolonial framework for global and planetary health, focusing on power structures within and between organisations and in collaboration with diverse experts, especially from underrepresented and excluded communities.

How we work

We work through a feminist lens

We focus on bottom-up approaches and participatory methods, valuing lived experience and practice, expressed through the voices of the people we work with.

Our trainings and facilitations are based on mutual understandings of inequalities and strive to create violence free spaces of communication and conduct.

Our approach is intersectional and transformative. We negotiate diverse settings and support solutions that challenge the status quo.

We strive to position ourselves in the complex power dynamics that accompany consulting and research.

We work to make power relationships visible, uncovering unconscious biases and enabling dialogue.

We strongly believe in utopias; we believe a better world is possible.

Our Consultants

We work with a number of qualified consultants with expertise in Global Health, gender and the environment. The majority of our consultants have many years of experience in global development work, but we also train and prepare young consultants. We believe that diverse teams with varied perspectives are better able to produce sustainable solutions for global challenges.

We provide our consultants administrative and technical support and assist with project management where necessary. The rising number of cross-sectional projects demands new skills in the area of digitization, agile methods, and alternative work and management concepts. We support consultants by offering in-house and external training in these areas.
