Scientific Programme

This conference will bring together researchers in organic agriculture in the tropics for discussing scientific developments in this intriguing domain. Attention will also be given to more practical issues such as marketing and certification, and we would very much like to stimulate interaction between scientists and practitioners/NGOs/government bodies in order to finetune research priorities and identify major bottlenecks for further development of organic agriculture in the tropics. To this end, we foresee the organization of a number of practical workshops.

The conference will consist of a number of plenary, oral presentations, and, depending on contributions received, a number of parallel oral presentations. Much attention will be given also to poster sessions, where we expect active involvement of both poster presenters and other participants.

Update: Detailed of the conference programme can be seen below.

Themes of the conference

The conference will be kept very broad and can deal in principle with all aspects of organic agriculture in the tropics. Sessions will be arranged around a number of themes, depending on the contributions received, and include:

  • Soil management and soil quality

Nutrient supply, nutrient use efficiency, nutrient losses, soil quality, relation between soil quality and soil functions, restoration of soil quality upon conversion to organic farming.

  • Natural plant protection

Soil disease suppressiveness, prevention of pests and diseases, weed management, natural pesticides.

  • Organic livestock production

Origin of livestock, livestock feed, living conditions, waste management, and health care.

  • Food quality and food safety

Nutrient content, freshness, taste and appearance, production and processing method.

  • Organic farming and climate change

Organic farming and the challange of climate changes, organic farming and carbon footprint

  • Smart energy and agriculture:

Renewable energy and farming, biomassa energy, bioenergy production, energy farming efficiency

  • Economic analysis of organic farming

Direct and/or modelling comparisons of economic returns between organic and conventional farms, social cost and benefits, macro-and microeconomic of organic farming, economic feasibility and risk.

  • Soil bio-technology

Bio-fertilizer, bio-pesticide, microbiology

  • Other themes

Free themes based on personal interesting related to organic farming
