Godlove Kihupi

Communication and marketing - Dodoma region

'Born and raised in Dodoma, central Tanzania, I always hear old people saying that the place was once like the garden of Eden with lots of harvests, trees and all-season rivers. This has remained a history and there is a threat of it to become a desert in the near future. I have always wished to return the environment back to its original condition. Through the opportunity I have got to work with Justdiggit, I believe my ambitious dream of regreening Dodoma region is becoming a reality.'

Njamasi Chiwanga

Program Manager - Regreening Dodoma Program

'I believe that working closely together with local people is not only wonderful; it is necessary to successfully achieve our shared goals.'

Lieke Hulshof

Project Coordinator Dodoma region

'Social marketing is my passion, and climate change is one of the biggest challenges for mankind but also a pretty political subject fort he average person. By promoting our positive solution driven projects to the world we can make a huge difference on the ground in Africa and in the hearts and minds of people around the world. #Justdiggit'

I want to share (transferring) the wisdom and culture of the Maasai with the world and provide avenues of community empowerment - economically, socially and culturally. I am a conservationist committed to bringing conservation solutions to preserve the wildlife and empower and sustain the people.'

How it all started!

Co-founder Dennis Karpes

“Since ‘2000 I decided to become a change maker for many reasons. I really had the feeling something needed to change for creating a better world and I also had the feeling that I could be the one creating this change. One of the better decisions in my life! After the successes of Kuyichi and Dance4life I was ready for a new social venture. In 2009 I met the unique Peter Westerveld and he showed me positive results of his own landscape restoration projects in various African countries. I was sold from the first minute, because I saw that these restoration projects had multiple benefits on big issues like water, food, biodiversity, migration and of course our suffering climate. Together with Peter I founded Justdiggit to show the world solutions, hope and positivism. Unfortunately Peter passed away in 2014, but Justdiggit is more alive than ever and a green revolution is in the making!”
