Project Description

Research Subject

The interdisciplinary research group EGON investigates the development of organically bred fruit varieties in commons-based initiatives. This breeding approach is characterized by the utilization of the genetic diversity of heirloom and underutilized varieties in breeding, as well as the practical participation of a community of farmers and breeders. In EGON, studies are conducted from different perspectives in order to evaluate this breeding approach ecologically, economically, and socially.


The following major research questions are discussed:

  • - How can organic regional fruit farming be secured, innovative breeding concepts be developed and established, and the access to fruit cultivars be kept open?
  • - What are the differences of the conducted participatory organic fruit breeding approach in comparison to other breeding approaches?
  • - What ecological, societal, and economic impacts does the conducted participatory organic fruit breeding approach have under which conditions?
  • - What are the implications of the genetic diversity regarding the used cultivars in the breeding process?


The research contributions should also be transferable to other pome fruit varieties and should contribute to the discussion on sustainable orchards, agrobiodiversity, and food sovereignty.

 

Approach

The project is characterized by a close and integrated form of cooperation between agricultural and breeding actors, organizations, and scientific partners. In addition to a regular cross-disciplinary and problem-oriented exchange of knowledge between the research and practice partners, excursions, conference visits, or courses are held together at the UOL. In addition, practitioners from the organic fruit-growing and -trade are involved in the research process through transdisciplinary workshops to discuss project results in a timely manner in terms of adequacy and feasibility.


Overall, EGON follows the research approach of interdisciplinarity and transdisciplinarity. The definition and development of the research project in the preliminary phase of the project took place in close coordination and at eye level between the research and practice partners. Research contributions from the project should have a practical relevance for fruit growing and breeding. EGON is divided into three subprojects, which are in regular exchange with each other:

 

  1. Applied subproject: Practical organic and participatory apple and pear cultivation by the practice partner Apfel:gut.
  2. Natural science subproject: Analysis and assessment of the genetic diversity of a wide and diverse range of apple varieties well used in the project of Apfel:gut.
  3. Social science subproject: Conceptualization, ecological-economic analysis and evaluation of the commons-based breeding approach as well as elaboration of a marketing strategy for the emerging varieties.

Project Duration

2017-2019

extended until July 2020

Funding

The state government of Lower Saxony promotes the three-year project from the “Niedersächsisches Vorab der Volkswagenstiftung”. The research group is one out of five projects, which are promoted by the state government to strengthen sustainable agricultural production from 2017 onwards.

Partners (Research)

Working on the project are the coordinator Prof. Dr. Bernd Siebenhüner, chair for “Ecological Economics”, Prof. Dr. Dirk Albach, leader of the working group “Biodiversity and Evolution of Plants”, und Prof. Dr. Stefanie Sievers-Glotzbach, junior professor for “Economy of Commons”.

 

Practical Partners

The organization “Saat:gut e.V.“ with its ecological and participatory project “Apfel:gut” as well as the “Öko-Obstbau Norddeutschland”- an organization for consultation and experimentation in organic fruit farming- are going to be responsible for the practical breeding.

Including the botanical garden of the University Oldenburg as a breeding yard for apples, the network of apple breeders is going to be expanded by one further scientific institution. The goal is to establish the botanical garden as a location for the organic cultivation of apples in the long term and to integrate it in the existing network.
