Hi I’m Paul,

Originally from the UK I moved over to Bulgaria with my family 12 years ago and set up the Balkan Ecology Project. Prior to that, I worked as a freelance Arborist in the UK for 15 years. Balkan Ecology Project is a family project run by myself, Sophie and our two boys Dylan and Archie, and supported by the amazing volunteers we have hosted here over the years. We aim to develop and promote practices that provide nutritious affordable food while enhancing biodiversity and work to achieve this by:

– Researching, designing and implementing systems on the ground
– Providing working examples of our designs at our sites open for the public to visit
– Providing quality education and training to aspiring growers and landscapers
– Providing consultancy and design for landowners and farmers across Europe
– Practicing an open source policy, whereby we disseminate our results freely and share all aspects of our work
– Growing, selling and promoting the use of plants and plant communities that have high ecological and nutritional value

Our activities currently include: Biological Plant Nursery, Educational Courses, Local Land Stewardship, Polyculture Research, Market Gardening​, and Consultancy and Design.

Nitrogen Fixing Species for Agroforestry Systems


I am currently working on a Regenerative Landscape Design for a site in Todorovo, Bulgaria. The plan is to establish an Agroforestry system known as Alley Cropping wherein rows of mixed species edible trees and shrubs are planted at intervals with spaces for herbs, forage and/or grain crops to be grown in between. It’s a dynamic system which is inherently diverse, providing multiple yields and excellent habitat for wildlife while at the same time being relatively resilient to a changing climate.

Biological Fertiliser – Human Urine


Human urine provides an excellent source of nitrogen, phosphorous, potassium and trace elements for plants, and can be delivered in a form that’s perfect for assimilation. With a constant, year-round and free supply of this resource available, more and more farmers and gardeners are making use of it.

Urine is 95% water. The other 5% consists of urea (around 2.5%), and a mixture of minerals, salts, hormones and enzymes.

Comfrey – BELIEVE the HYPE!

When writing this article I could not resist to include some of the stories of this incredible plant and of the […]

Perennial Polycultures – The Biomass Belt: Fertility Without Manure


We’re extending the Polyculture Project to include experimental perennial polycultures on various plots of our newly acquired land. Our aim is to develop models that are low cost to establish and maintain, can produce healthy affordable nutritious food and will enhance biodiversity. We’ve been looking into fencing our plots, and how to meet fertility demands of the establishing perennial crops such as fruits, nuts, herbs and perennial vegetables without relying […]
