Ruth Olari Proscovia is a dedicated development practitioner from Uganda with a passion for social transformation through the principles of Nonviolent Communication (NVC).

Ruth was introduced to NVC in 2019 during her peacebuilding work in the communities of the Teso sub-region in eastern Uganda, particularly in the prevention and response to Gender-Based Violence (GBV) and Violence Against Women and Girls (VAW). Through NVC, she learned how to build and maintain relationships, partnerships, and collaborations that promote mutual respect for the feelings and needs of all, with the awareness that every human being has needs that matter.

Ruth's commitment to NVC has led her to participate in extensive NVC training programs facilitated by trainers from the Center for Nonviolent Communication (CNVC), including a 9-day International Intensive Training on NVC in Tanzania (2022), a 10-day Residential NVC training in Uganda in November 2023, and a 10-day Residential NVC training in Kenya in December 2023. These experiences have equipped her with invaluable skills for facilitating training and discussions that significantly enhance the quality of life and promote harmony in society.

Ruth has accumulated over five years of experience engaging communities and leaders in meaningful conversations aimed at addressing the deep-rooted challenges faced by underserved populations. She has done this through training, collaborations, partnerships, Alternative Dispute Resolution (mediation), appropriate referrals, counseling, and providing empathy to survivors of gender-based violence. She coordinates dialogues among community leaders—male and female cultural, religious, political, and government leaders, as well as policymakers—to influence policies, by-laws, and ordinances that support equality between men and women for peaceful coexistence in the Teso sub-region of eastern Uganda.

Ruth is currently leading a women and girls' social change initiative (the Women and Girls Empowerment Program), which seeks to empower survivors of obstetric fistula in the Northern, Eastern, and Central regions of Uganda by providing them with skills, capacity, and knowledge in civic education and advocacy. She applies NVC principles to offer psychosocial support and empathy to survivors of obstetric fistula and GBV, facilitating dialogues with policymakers, health workers, civil society organizations, government leaders, and survivors to advocate for improved maternal health outcomes in Uganda.

Through her work, Ruth passionately advocates for community engagement, partnerships, collaborations, alliances, and movements among like-minded individuals, organizations, policymakers, politicians, and government leaders to promote policy frameworks that support proper planning and decision-making for national development. Her efforts aim to uplift and empower marginalized communities, fostering a culture of understanding and empathy.

Hey, welcome, I’m Sebastian,


Married, two adult kids and a cat.

Since 2018 my ever growing passion is to live and promote NVC wherever I am!


As a former airline pilot I am retired since 2016, and through NVC have gained a much deeper meaning and a real purpose in my life since then!

 

I do a lot of volunteer work, in a hospice, in a high school and with elderly people.

I am a certified Mediator on NVC basis, host practice groups in NVC-Mediation, Restorative Circles and NVC.

I give NVC workshops in schools, hospice and communities.

I answer the conflict-hotline of the federal association of German mediators.

I host an NVC practice group with inmates of a prison.

I am a board member of the ‚Network NVC Darmstadt-Südhessen e.V.‘ and co-founder of the ‚Network NVC Mainz-Wiesbaden‘.


I  feel a humble gratitude for this opportunity to contribute to the IIT in Sayda and look forward to this profound experience!

My journey with NVC started In 2014 when I received a copy of Marshall Rosenberg’s book: NonViolent Communication, A language for Life, in Swedish. Being bilingual, I proceeded to read it in English as well. 

My initial reason for reading the book was that I was searching for a solution to improve my relationship with a family member, what I discovered along the way, was that every single one of my relationships has shifted, and this without the others knowing what NVC is! The relationship that has benefited the most is the one with me, myself and I.  I have found a level of internal peace, I didn't know existed! I have found a way home to myself, my heart, what matters, and happiness.

I was hooked!

Since 2014, I have taken numerous courses in NVC and held them as well, be it online, in person, in different countries and in both Swedish and English.
