The AIPH International Conference: The Path to Sustainability in Ornamental Horticulture boasted a line-up of expert panellists from around the world. Each shared their unique insights and actions as part of one of four focussed panel sessions.
By Ron van der Ploeg
Organised by The International Association of Horticultural Producers (AIPH) in partnership with GreenTech Live & Online, Floriculture Sustainability Initiative (FSI) and FloraCulture International (FCI). The online conference took place on 30 September 2021.
Why should our industry change?
Helping to set the scene for the day ahead was David Bek, a Reader in Sustainable Economies at Coventry University (UK). He said that the pandemic has reminded people of their vulnerability (and has revealed supply chain vulnerability).
Covid-19 caused drastic changes concerning consumer needs with Fairtrade and locally grown and health products being in high demand. Bek said that a certain tranch of wealthier consumers put their money where their mouth is. Also, some middle-class consumers had more money in their pockets because they weren’t going on holidays.
However, post-Covid, life starts to cost a lot more due to price hikes in all kinds of commodities including energy. So Bek finds it difficult to predict whether the willingness to pay for sustainable products including eco-certified cut flowers and plants will stick.
The impact of climate change
Bek went on to explain what climate change means for horticulture. Changes in temperature and rainfall regimes, exotic weather events, and rising sea levels threaten the viability of production areas across the globe. Whilst higher winter temperatures in Northern Europe may sound appealing in fact the impact of melting ice sheets and glaciers are anything but. The sub-Sahara is already struggling with temperature and rainfall changes and projections for horticultural heartlands such countries such as Kenya and Ethiopia do not look good. Another horticultural powerhouse, the Netherlands will face serious problems with rising sea levels.

Futureproofing your business
The insurance industry has been ahead of the game in terms of adjusting its risk rising policies whilst investors are also taking climate change very seriously. The profile potential investments carefully against climate change risk. Simply put: if you as a horticultural entrepreneur want insurance or investment then be ready to demonstrate your climate change mitigation planning.
Bek invited his audience to consider that for all their green benefits, horticultural activities contribute to climate change. Carbon and water footprint can be tracked throughout the supply chain. “Researching these is complicated and time consuming but we have to acknowledge the consequences of some of the work that has been undertaken. For example, an evaluation of cut flower supply chains have produced sobering data. According to one widely cited study the carbon footprint of a rose stem grown in Kenya is 2.407kg whilst one grown in Holland is 2.437kg. Put this in context, a bunch of bananas is 0.5kg. And when we think of water, one study on water footprints indicated that an average Kenyan rose stem has a water footprint of 9 litres which is a considerable amount.”
Life cycle analysis
At the same time, science is evolving to enable a greater understanding of where footprints are occurring within supply chains and the extent of the impacts. Life Cycle Analysis is a key tool for enabling this process. Bek said, “Different products generate problematic output at different stages of their production. Behind mapping these outputs is a process of quantifying these outputs which in turn enables hotspots such as production of greenhouse gases to be identified.”
He said that it is vital that the industry engages in these types of analysis so that problem impacts are reduced or even eradicated.
Proactive solutions – not defensive reasoning
The value to society of non-food and non-health products became very contentious during the pandemic. “Items that were considered as non-essential by some governments and retailers were deprioritised or even banned from sale. And this included flowers and plants in some countries. “This perception of essentialness matters in the context of climate change. One of the world’s leading carbon footprint experts told me a couple of years ago there is no justification to producing cut flowers in heated greenhouses or fly them halfway around the world.”
Bek said that whatever our own perspectives are the sector has to be mindful that policymakers and consumers will be making tough trade-offs in the coming years as the imperatives to confront the climate crisis.
On the positive side, Bek stressed how horticulture has a vital role to play in tackling the climate crisis. He said, “Plants in the right place, the right amount of time are essential for capturing carbon, improving water management, regulating temperature, and promoting biodiversity.Living green is an important contributor to the pathway of net zero. And it is not all about rainforests. These principles apply to urban parks, street design, and residential development. Collectively all these spaces contribute to climate mitigation if managed correctly.”
Horticulture has a huge role to play in providing the tools to tackle the problem and in communication and lobbying. Bek referenced the surge in sustainability initiatives in recent years with FSI leading the way and going from strength to strength.
Bek noted that science and research are critical in the process going forward. He welcomed the increasing role research institutes are playing. An example is the programme of work being undertaken by WUR University in the Netherlands in delivering life cycle analysis of products in order to produce horti-footprints.
Bek said, “The WUR programme is particularly important because it is developing a standardised approach for benchmarking environmental impacts of horticultural products throughout the entire supply chain, from soil to mouth, from farm to fork. Cross-industry collaboration is crucial in these processes. The information must be shared and not held back to benefit USP’s or brand identities of a handful of stakeholders. It is in everyone s interest to ensure that the horticultural sector is not just achieving in reducing its negative impacts but is actively contributing to climate change mitigation
Bek concluded by saying that during pandemics we all have witnessed the ability of humans to adapt when the pressure is on. “This is a crucial learing in the context of climate crisis. We cannot change has been a repeated statement during recent decades in relation to reducing greenhouse gas emmisions. But we now have proof that as individuals, as a society and as businesses we can change overnight in terms of our behavour if we have to.”
