In June this year, I was chosen for one of two teams attending the 2024 International Food and Agribusiness Management Association (IFAMA) Case Study Competition and Conference in Almeria, Spain. The theme of the conference was Food Security Through Innovation & Sustainability. We were then invited to attend a weeklong food and agri-innovation tour to Bologna, Cologne and then through the Netherlands.

I am lucky to have been in a team with four clever individuals from across the New Zealand Agri-Food sector. Our team included Dan from Silver Fern Farms in Dunedin, Fatima from ANZ in Auckland, Braydon from Perrin Ag in Rotorua, and Katie from Auckland University. We brought a diverse range of skills to our case study analysis, as well as a diverse range of opinions and perspectives on agriculture.

We were incredibly excited to learn that we won first place in our division, with the other New Zealand team coming in second place. Not bad for a little country at the bottom of the world!

While travelling together after the conference we were able to explore food provenance and food culture in Bologna, agricultural research and development in Cologne, and agricultural and horticultural innovation in the Netherlands. We will all be spending the next few months digesting what we have seen, discussed and learnt, and how our experience links to food production back here in New Zealand.

Many thanks to LandWISE (Dan & Phillipa) for allowing me the time away to learn, grow and explore the agri-food sector at a global level.

Almería – a sea of greenhouses

At the bottom of Spain on the edge of the Mediterranean Sea, you’ll find Almería. Almería is a city and municipality of Andalusia, and is located in the desert, receiving only 200 mm of rain per year. Despite this, the region is a hub of horticultural production, with 32,200 ha of greenhouses spread across the landscape (3.7% of the total area of the province), as well as around 30,000 of open-air production.

There are 12,500 farms with undercover production which generate more than 110,000 jobs. There are many small growers who are represented by grower co-operatives. In fact, there are enough co-operatives that secondary co-operatives exists which are ‘co-operatives of co-operatives’, for example Unica, which represents 15 co-operatives. The industry prides itself on being leaders in tech transfer to growers of all sizes, and strives for shared wealth creation, and keeping small farmers in business.

The annual turnover in the region is €4.4 billion, plus an additional €1.5 billion from the auxiliary industries including nurseries, R&D centers and suppliers (approx. €6 billion total per year). Given the region’s warm location, growers can achieve year-round production. The main crops grown are eggplants, zucchini, cucumber, tomato, pepper, melon, watermelon and lettuce. In total, 3.7 million tons of fruit and vegetables are produced each year. The first greenhouse was built in 1963 and since then has taken the province from one of the poorest in Andalusia to one of the wealthiest, now ranking above average in Spain.

In 2007 a program was started to implement biological controls in horticultural crops to produce residue free crops. In 2023, Almería had the largest area in the world using biological controls in vegetables, totaling 26,800ha.

Challenges

There are significant challenges to producing food in such an intensive way, and there has been much criticism of the region’s intensive production methods and the impact on the environment.

Water is unsurprisingly a key issue in a desert. Historically water has been extracted from groundwater, depleting underground aquifers. In recent years, desalination plants have been built to provide fresh water through reverse osmosis for both human consumption and irrigation, although water is still having to be extracted from the ground to meet demand.

Plastic use is also a challenge, with the plastic on the greenhouses being replaced by growers every 3 years, however the industry reports that 100% of the plastic is recycled.

The source of the region’s labour supply has faced criticism in recent years, in relation to the exploitation of migrant workers working in the greenhouses.

Netherlands- home of the modern glasshouse

As part of our trip, we travelled through The Netherlands, where we had the opportunity to visit Van der Harg in Bemmel. They grow and pack capsicums/bell pepper in their 8.6 ha of glasshouses. They are also experimenting with growing eggplants. The design of the Dutch glasshouse originated in Den Hague, and there are 10,000 ha of glasshouses in The Netherlands today, which largely grow bell pepper, eggplant, tomato and cucumbers.

The seedlings are grown at an independent nursery and planted into the glasshouse in November. The first fruit is harvested in February. Production lasts until October when the plants are pulled out and the greenhouse is prepared for the next crop. Interestingly, the crop is grown with few to no sprays, however the crop cannot be classified as organic as it is not grown directly in the soil. The plants are grown in ‘cultivation gutters’, where there are understory plantings which are used for pest control, and climate control.

The glasshouse is located in an Agropark, NextGarden, which allows participating growers to reduce their costs by ‘industrial symbiosis’; sharing resources and infrastructure. This includes collective power generation and a biodigester. By-products of the biodigester are captured (heat and CO2) and used by the glasshouses. There is also collective water harvesting systems that delivers clean rainwater for irrigation and processing.

Challenges

There are of course challenges to this system. The process of harvesting is labour intensive, with the labour supply coming from largely from countries like Romania. A robotic harvester has been developed, however must harvest ’27 hours a day’ to be the same cost as a human. Once they reach 24 hours, the human element of production will largely be gone.

Additionally, the strings used for training the capsicum plants are plastic. To maintain production levels they are not able to use biodegradable strings as they are not transparent enough and block too much light. The plastic string is used for just one season and is the major waste product of the system.

This system is energy intensive, particularly in heating over the winter months. However, Van der Harg are working with NextGarden Agropark to reduce or capture emissions, to power the glasshouse in a sustainable way.

Same challenges, different growing system

Regardless of growing system or location, the same conversations are happening globally, in relation to the challenges growers face. Water, energy, ethical labour supply, agrichemical use, and plastics are issues facing farmers and growers regardless of system or size.
