Bridging the World through Horticulture


During the 30th International Horticultural Congress (IHC2018) to be held in Istanbul, Turkey between 12 and 16, August 2018, workshops will be organized after the symposia sessions. Workshops are proposed by the conveners with various objectives as:

  • establishing an international expert group,
  • sharing experiences and skills,
  • carrying out in depth discussions on a specific topic,
  • extending the network and/or
  • seeking cooperation opportunities

The format of each Workshop may be different based upon the initial objective. You can register to any workshop that may be of interest to you. The output of the workshop(s) may be compiled but will not lead to a Congress proceeding, 'Acta Horticulturae'. A workshop, if linked to a specific symposium, will be scheduled to allow participation to both activities. However, a workshop may be completely independent from any IHC2018 symposium.

The general rules for IHC 2018 registration also apply for the workshops.

The world fruit market has developed significantly in the past two decades. Aside from quality, the health benefits of fruit consumption have been promoted extensively, and the term "superfruits” gained significant usage and attention in recent years as a term synonymous with the marketing strategy to promote the health benefits of certain fruits, including pomegranates, cranberries and blueberries. In addition, the biodiversity of fruits, i.e., the individual varieties and cultivars, are attracting attention, as the nutrients and bioactive non-nutrients within species can vary dramatically. Several cooperatives and associations that produce and market these fruits have developed an effective strategy using the content of "antiauxidants” in their fruits as an indicator for promoting the health benefits of their fruits.

Scientists and nutritionists have differing points of view on the use of the term. Some claim that there is no scientifically objective assessment of the potential health benefits of fruits in this category. Similarly, there is no definitive list of superfruits and new fruits are regularly put forward as superfruits. In addition to pomegranates, blueberries and cranberries, examples include acai, avocado, mangosteen, blackberry, raspberry, strawberry, lingonberry, certain banana varieties and yumberry. However, most fruits are packed with nutrients and yet, some are not perceived as being "Super”.

Food and Agriculture Organization of the United Nations (FAO) along with International Tropical Fruits Network (TFNet) and Ministry of Agriculture and Rural Development, Vietnam organized International Symposium on Superfruits: Myth or Truth from 1-3 July,2013 at Ho Chi Minh City, Vietnam to examine latest research findings to determine whether there were nutritional and agronomical evidence to support the claim of a fruit (species and varieties) being a "Superfruit” and whether there were adequate information available to provide a definition.

In regard to scientific definition of "superfruits” the Symposium concluded that the label "superfruits” based on two criteria: the nutritive value and extranutritional benefits. Although antiauxidants capacity is the most widely recognized attribute of a superfruit, most scientists realize that this is only a small part of the overall picture. Bioactive molecules may have potential health benefits independent or additional to their antioxidant effect. Further comprehensive research is needed to fully understand the metabolic pathways and biological role of the bioactive compounds responsible for the benefits observed on health. However, final validation should be obtained with tests in vivo.
Currently those marketing fruit are not allowed to promote them as "Superfruit” because this term is not accepted by EU,USA or food authorities from some other countries. This will not change until science has demonstrated unequivocally that intake fruit confers specific and consistent health benefits.

The Workshop will address:

  • Charecteristics of fruits that can be labelled as superfruits
  • List of fruits that has potential to be called superfruits.
  • Networking ties with researchers, FAO, TFNet and Government to promote listed superfruits.

Agroecology is a scientific discipline, a social and political movement and an agricultural practice that brings together, synthesizes and applies knowledge of agronomy, ecology, sociology, ethno botany, and other related sciences, with a holistic, systemic and strong ethical component, in order to generate knowledge, validate and apply adequate strategies to design, manage and evaluate sustainable agroecosystems.

The scales and dimensions of agroecological investigations go from plot and field scales to agroecosystem and farm scales and research covering the whole food system.

The transdisciplinary and multidimensional character of agroecology makes it possible to overcome the fragmentation and segmentation of knowledge in agricultural and teaching practices; demands participatory processes between social actors and the community as a whole; contributing to establish a holistic formation to intervene in a propositive way in the problems of the territory.

Agroecology is conceived as a holistic model of global change that includes technical, social, organizational and political dimensions. It favors new learning conditions by abandoning old, compartmentalized models of knowledge in which disciplines often ignore the complex realities of human, agricultural, and natural environments. Learning from action research provides answers to immediate questions and contributes in the long run to the consolidation of a sustainable food system based on local reality knowledge and with students prepared to deal with complex problems in the future.

Teaching of agroecology, due to its systemic approach, intervenes in the articulation between learning and the development of capacities to apply and disseminate what has been acquired in various spaces at local and regional level, with the aim of providing tools for decision-making on the management of natural resources and climate change. That is, prioritize clear, medium and long-term strategies in relation to ecological, social, political and cultural aspects that promote sustainable agriculture.

This 3-hour workshop will address the following thematic areas:

- Agroecology as an organizing principle for future programs of higher education
- Holistic thinking as a methodological tool of agroecology education.
- How agroecology must be considered as a key focus to developing alternatives for solving the complex issues of hunger, poverty, food production, climate change, and agricultural sustainability
- Family farmers work, where local practice and knowledge are linked in ways that promote empowerment, opportunity, equity, and hope for women and men of all ages.
- Funds for research, training, and extension programs in agroecology, and recognition of researches that link science to practice and social change.
- Support social agroecological movements, through which research demands arise, to expand agroecology regionally.

Audience: We expect a participation of researchers, professors, extensionists, students, NGO, among others. 

Expected outcomes:

  • Consolidate agroecology in higher education towards the formation of solid professionals in the subject
  • Promote an agroecological network in the ISHS
  • Strengthen research and extension projects in agroecology with the methodology Participatory action research (PAR)
  • Join for a future symposium on agroecology

Leading ISHS Commission/Section Temperate Fruits in the Tropics and Subtropics WG

Temperate fruits require exposure to chilling to break dormancy. Chilling temperatures may be continuous, sequential, or alternating. Establishing appropriate protocols for breaking dormancy will allow more treatments that are effective in practice. Several techniques are available for breaking dormancy in the subtropics when chilling is insufficient; in the tropics, dormancy may be completely avoided by defoliation and/or chemical treatment.

Adequate winter chill is important for commercial orchards. Climate change may impact winter chilling. Thus various modeling methods were performed since 1970's to calculate the chilling accumulation to break dormancy. Climate change and milder winter temperatures will constrict chilling accumulation and will cause irregular flowering and fruit set. Also, higher rates of double fruit formation will be observed as a result of high temperatures during the flower differentiation period in warm climatic regions

The subject of this workshop is to address sustainability of deciduous fruit production under changing economic and climatic conditions of tropical and subtropical regions. Two invited speakers will present case studies on this subject. The workshop is expected to gather researchers, growers, nurserymen, and commercial horticulturists together to discuss the latest scientific findings to address current and future challenges to climate change, impact and mitigation strategy for the temperate fruits in the tropics and subtropics.

Major thematic areas for discussion:

Breeding, low chill temperate fruit cultivars, climate change effects on fruit yield, sustainability of deciduous fruit orchards, modeling systems on chilling accumulation and new strategies and chemicals on bud break.

Vertical farming is a promising new plant cultivation technology that aims to produce vegetables, fruits and medicinal plants in a closed environment with artificial light. Typically, vertical farming encompasses multiple layers of crops grown hydroponically using LED technology providing conditions for optimal plant growth and yield. The hydroponic cultivation system consists of a closed recirculating nutrient solution maximizing water use efficiency and no agricultural runoff or use of pesticides. Indoor cultivation and control over environmental conditions means no weather-related crop failures and it allows for year-round crop production. Other advantages of vertical farming are better control over food safety, local for local production or reduction of food transportation and land use.

Vertical farming is receiving a lot of attention in recent years because it is advocated by futurists with an interest in smart cities and building a circular economy. It also appeals to consumers who want to buy local food of high quality and freshness. Despite these interests and many advantages, the energy requirements and initial investment costs are still major obstacles for the commercial exploitation of vertical farming. Improvements in LED technology, clever use of energy sources available in the city, automated harvesting etc are helping vertical farming to turn into profitable plant production systems. In the last couple of years several large indoor farming systems have been constructed across the world paving the way for more general commercial exploitation. Further research is however required to improve the yield investment cost ratio, to lower energy requirements, to ensure disease free condition in the indoor systems etc.

Researchers, industry, government, growers and end-users are invited to share their ideas and discuss the technical, economic and legislative challenges that vertical farming is still facing. This workshop aims to create new partnerships and research collaborations, and to improve awareness of the upcoming potential of vertical farming. The challenges that need to be tackled and prioritization of new research activities will be discussed.

Main themes:

  • Vertical farming systems and closed loop hydroponics
  • LED light systems
  • Nutrient management and water use efficiency
  • Pest management in vertical farming systems
  • Development of a consumer driven short supply chain and economics of vertical farming
  • Waste reduction measure
