Eine Frau des Samburu Stammes.
Biovision’s projects promote self-determined livelihoods, for example for people affected by climate change. Noolangeli Tukuyen Lekalkuli of the Samburu tribe from Oldonyiro, Kenya, started keeping camels and has thus increased her resilience to droughts.

Gift certificates

Give your loved ones a contribution to one of Biovision’s priority projects – a meaningful gift that is always appreciated!

We will gladly send a certificate listing the donated amount and name of the beneficiary to your address so that you can then give it as a gift. Please pay for the donated amount here and include the name of the chosen certificate as a message.

Climate certificate for the project “Policy for Agroecology

Droughts, depleted soil, disease and pest infestations represent major challenges for smallholder agriculture in sub Saharan Africa. Biovision raises awareness about sustainable food systems among decision-makers and helps small farmers to combat climate change by adopting agroecological approaches.

Camel certificate for the project “Sustainable Grazeland Management

Livestock farming provides a livelihood for many people in Samburu, northern Kenya. However, grazing land has become degraded and scarce due to droughts, overuse and deforestation. Biovision supports grazing land committees to ensure sustainable grazeland management and promotes the development of additional sources of income – invasive plants are processed into fuel and animal feed and then sold, for example.

Beehive certificate for the project “Bees for young entrepreneurs

The beehive epitomizes action that helps people to help themselves. People in the Siraro region in Southern Ethiopia are often fighting against hunger, poverty and the effects of drought. Biovision is supporting them by providing training in beekeeping and the marketing of honey. This opens up new opportunities to earn money and makes them independent of emergency aid.

Event donations

Are you celebrating a birthday, wedding, anniversary, or any other occasion, whether in a private or business setting? An event donation offers you the opportunity to collect donations instead of gifts.

You have 2 options for collecting donations from your events:

  1. You collect the donations yourself and transfer the collected amount to us with a note (“Birthday Jane Doe”). You can find payment options here.
  2. You can distribute Biovision QR deposit slips at your event, which we will be happy to send to you by post. Your guests can thus make a donation to Biovision themselves and receive a donation receipt for the tax authorities. We will then send you a list of donors.

Feel free to contact us for further questions or if you would like supplementary documents, such as Biovision magazines, annual reports or a small gift (such as Post-it notepads or Biovision pens) for your event.

I am happy to help with any questions you might have!

Inheritances and legacies

Giving confidence and strength to future generations – for a healthy life in harmony with our planet.

Our foundation is increasingly receiving legacies and bequests from benefactors who wish to continue doing good for humanity and our planet beyond their lifetime.

We are touched by this deep connection with humankind and the world we live in. In silent remembrance, we thank all previous legatees for their timeless solidarity with all life.

«Many said I was mad»

Throughout my life, I have always had people who encouraged me,” says Roland von Ballmoos. For example, he learned an incredible amount from his mother. “She was the brains in the family and did the accounts for the family business”. In contrast, his father was a visionary. “From him I have my passion, the spirit of adventure and my love of fast cars,” he says with a smile.

With vision we can achieve great things

Romy Erb Knobel and Robert Knobel have travelled widely. Both love sport and can often be found touring in different countries – walking, cycling or skiing.

“If we are to preserve our beautiful planet, humans must live in harmony with nature – everything is interconnected. It is precisely this sentiment that the Biovision Foundation embraces with its holistic approach. I want my savings to be used in a way that is a genuine reflection of me and so I have named Biovision as a beneficiary in my will.”
