Agroecology & Institutions Challenges, opportunities and recent - PowerPoint PPT Presentation

Agroecology & Institutions Challenges, opportunities and recent examples from Argentina Pablo A. Tittonell National Program on Natural Resources and the Environment, INTA, Argentina

Agroecology & institutions – a mismatch 1. Organisations that deal with agriculture and rural development were not built around agroecology 2. Agroecology movements, scientists and activists are often weary of joining forces with ‘traditional’ institutions 3. Agroecology is perceived as hobby farming, or as pro-poor and unprofessional, or as elitist and snobby, or as politicised and combative, as being non-realistic, etc., etc. , etc…. Agroecology principles  Diversity  Resource efficiency  Recycling  Natural regulation ETC group  Synergies

Large scale rice-fish polycultures (Argentina) • 900 ha rice-fish system (and growing) • Use of a local fish species (Pacú) • Water and nutrient recycling • Agrochemical-free rice (9 t/ha) • Native grasses to outcompete weeds (Echinocloa) • Processing and cooling facilities • Challenge: reduce dependence on sojabean

agroecology 1. Agroecology requires innovative design 2. Agroecology requires landscape approaches 3. Farmers’ knowledge is central to dealing with system- and context-specificity 4. Social organisation and movements to foster learning and mutual support

Outreach questions • Inclusiveness – is agroecological food only for the wealthy? • Scalability – can any type of farmer go agroecological? • Sustainability – is this always granted through agroecology? • Resilience – can agroecology withstand global change?
