Eco Matser – Program Manager


Eco Matser has also started new programs such as the Energy Change Lab, creating space for dangerous thinking, exploring complex ideas, and searching for innovative solutions in the energy domain in Tanzania and globally (Energy Change Lab).

He also started the Sumba Iconic Island program, where Indonesian governments, civils society organizations and private sector work together to provide 100% renewable energy for the 700.000 inhabitants of this poor Indonesian island. With this program, Sumba will turn this into a leading example of 100% renewable energy (Sumba Iconic Island).

Eco Matser is based in the Hivos Global Office in The Hague but visits the regions frequently to work closely with the regional project leaders and partners to deliver the results on Green and Inclusive Energy.

Maimuna Kabatesi – Advocacy Officer East Africa

Maimuna Kabatesi has a background in Environment and Development and has worked in various capacities in the environmental sector including climate change, energy and agriculture.

Currently Maimuna is managing the Green & Inclusive Energy program at Hivos East Africa, working in Kenya and Tanzania. The program is working with different actors including county/district and national governments, other civil society and media among others towards the common goal of increased energy access and inclusivity in the energy sector.

She particularly enjoys thinking of new ways to communicate the message of green and inclusive energy -to get new and previously unheard voices involved in the fight for universal energy access.

“It’s fantastic to work and have real impact not only on policies and processes so that they are more inclusive, but also people’s lives through connecting citizens to those currently guiding the energy transition. The more inclusive we are, the closer we get to universal clean energy access for all.”
