High Value Vegetables, Root and Tuber Crops and Edible Fungi – Production, Supply and Demand

Sponsored by the ISHS Sections Vegetables and Root & Tuber Crops and the Commissions of Protected Cultivation and Horticultural Engineering

The International Symposium on High Value Vegetables will be held in Brisbane, Australia in 2014 as part of the International Horticultural Congress (IHC2014).

Statistics and many reports tell us that the daily intake recommendations for vegetables are rarely met in today’s society. Both fruit and vegetables are a great source of dietary fibre, essential vitamins and nutrients essential for optimum metabolic function. This deficit represents a marketing opportunity for horticultural producers around the world, as well as being an opportunity for the health and medical industry to reduce health care costs associated with poorly balanced diets. With public health systems around the world under strain from excessive demand and financial constraints, a combined effort from horticultural industries, research, development and extension agencies, health specialists and value chain specialists is needed to increase awareness of the value and benefits of vegetables and edible fungi in diets. High value vegetables and edible fungi also need to be defined in terms other than just health (nutrition, human disease control), but also to include sensory quality, convenience, and ‘belief’ values (eg ‘I will only buy vegetables I know have not affected the environment when grown’). It is well known that the expanding population will place additional demand on agricultural production systems, and that their diversity, productivity, resilience, profitability and sustainability will need to be improved to meet the increasing demands for quality, nutritious food. Modern tools of enhanced plant improvement, precision in agronomic practice, careful resource management and sophisticated post harvest practices in the value chain from farm to consumer will need to be deployed if these challenges are to be met. Vegetables represent a sustainable source of proteins, vitamins, minerals and other nutritional factors such as antioxidants. Increasing the concentration of these while retaining or preferably increasing yields has the potential to enhance human health while creating extra demand and underpinning sustainability of vegetable growers.

The International Horticultural Congress High Value Vegetable Symposium is expected to run for at least two days, with sessions and themes devoted to agronomy, plant protection, post-harvest market chain, processing and nutrition issues, and climate impacts.

We expect the symposium to attract professionals involved in all facets of the vegetable and edible fungi industries. Plant breeders, biotechnologists, agronomists, plant protection specialists, value chain innovators, post-harvest specialists, human nutritionists, allied health professionals and marketing chain specialists from a diverse range of businesses and industry will be represented. We anticipate that participants in the symposium will come from both developed and developing countries, and from International as well as national research agencies and funding bodies. This symposium and the symposium on Indigenous Vegetables (Symposium 13) are expected to run consecutively as this will allow interested vegetable specialists to attend both symposia.

Symposium theme

The overall Symposium theme is "Designing systems to deliver high value vegetable crops and edible fungi", with following sub themes:

Designing crops with high value traits

  • Genetic tools for high value traits
  • Molecular biology of high value traits

Designing production systems for high value vegetables – environment

  • System changes, mechanisation, precision and robotics for improved environmental and soil resource outcomes
  • Climate change impacts on vegetable cropping systems
  • Modifying systems to reduce carbon footprints
  • Minimising pests - Improved effectiveness of pest and diseases management.
  • Water and nutrient efficiencies – optimising the environmental x production outcomes matrix

Designing production systems for high value vegetables – crop production

  • Input management for improved crop productivity systems
  • Crop nutrition and fertiliser systems for enhanced human health
  • Edible fungi systems – bringing new production technologies to the light
  • Vegetables and human health – the future of functional foods in the modern world
  • Modelling system scenarios to improve crop yield and quality

Delivering high value vegetable crops – quality and convenience

  • The post-harvest chain - storage and logistic systems to preserve freshness quality
  • Packaging for convenience and improved product quality: a plastic conflict with environmental outcomes?
  • Innovation in the value chain – getting more product to end users by processing, developing futuristic products and processing technologies for new markets, adding value
  • Wasting away – breaking the low consumption high waste paradigm to deliver a healthy food supply system

Markets and consumers

  • Consumer perceptions and expectations - are they realistic, can they be met profitably?
  • Value chain analysis – identifying market opportunities, capturing value
  • Food miles – an increased carbon footprint or just hot air?

Keynote Speakers

Dr David Firman is Head of the Potato Agronomy Group at Cambridge University Farm - now part of the UK’s National Institute of Agricultural Botany. He obtained a degree in Natural Sciences at the University of Cambridge where he remained to complete a PhD on leaf growth and senescence in potato. His research interests over the past 25 years at Cambridge have spanned a wide range of projects from crop nutrition, foliar and tuber diseases, seed physiology and crop modelling. These projects have led to many practical applications adopted by potato growers in the UK and elsewhere including variety specific nitrogen rates, control of tuber blemishing diseases, limiting virus spread and seed rates accounting for seed age that maximise marketable yield. Through the Cambridge University Potato Growers Research Association, David maintains close linkages with growers and the wider potato industry to enable effective communication and practical adoption of research findings. He oversees the development of yield and irrigation modelling systems which are increasingly being adopted by collaborators to improve efficiency and productivity and provide data to guide strategic decisions.
