eco-design in fruit and vegetable farming systems

INTRODUCTION From 2015 to 2017, The French national technical institute CTIFL as part of AGRIBALYSE program (ADEME, 2017) developed a project on fruit and vegetable production with two main aims : - providing benchmark LCIs for 20 of the most consumed fruits and vegetables, - looking for eco-design options to improve environmental performances and further engage the growers in sustainable practices. The LCIs will be included in the next update of AGRIBALYSE database. From then, combined with other international references, benchmark LCIs for the 10 most consumed fruits and the 10 most consumed vegetables in France will be available.

The hypothesis of 10% yield reduction needs to be confirmed in the coming years. Also rain cover could maybe be improved in order to lower the yield losses. If the benefit is limited on climate change impact, the rain-cover-option is interesting regarding ecotoxicity, as it reduces by more than four times the impact.

This installation enables farmers to act immediately after rain episodes against fungal diseases for more efficiency, save time and labor, and reduce exposure risks for workers. GHG reduction could be further improved by using French grid electricity instead of a tractor to activate the compressor. However, this solution does not reduce significantly phytosanitary product use, and has therefore little effect on toxicity impacts. Nevertheless, the management system "fixed spraying" is still interesting for both conventional and organic orchards. Scab tolerant/resistant cultivars are the only solution raising positive gain in all impact categories, thanks to a reduction of spraying operations (less tractor use) and less phytosanitary product use. The farmer depends on the availability of such cultivar, and the market demand for these fruits. So far it represents only 10% of the production. Consumer education could be useful to further develop this solution, as those cultivars have different properties than conventional ones: conservation, aspect, taste etc. Also consumers tend to be more receptive to organic or zero pesticide approach than a reduction (even if it is a large one). In any case, this is a promising option for the future for conventional and organic systems. MATERIAL AND METHODS LCIs for national average apple were calculated in AGRIBALYSE 1. The results were presented to a group of experts in apple production (growers, technicians and scientists). GHG emissions hotspots were discussed and experts proposed some options to reduce environmental impacts, based on technics developed in research centers or tested in innovative farms. These solutions were incorporated within crop management system then assessed through LCA, always following AGRIBALYSE methodology (Koch and Salou, 2016) and using Means tool (INRA, 2017) .

In the future, new farming technics will be available to the farmers, e.g. for pest management, water use or tree fertilizing. Proving their efficiency will require sound environmental assessment. Also, taking into account wood carbon storage and grass strip s soil carbon in the footprint could highlight new options and encourage producers to change the orchard's end of life management.

ECO-DESIGN IN FRUIT AND VEGETABLE FARMING SYSTEMS.

AGRIBALYSE LEARNING WITH A FOCUS ON APPLE PRODUCTION.

RESULTS - DISCUSSION

Fig. 1. GHG emissions for different scenarios

Figure 1 shows the climate change indicator for the different scenarios and table 2 the results for

the 18 ILCD impact categories compared to a conventional baseline.

The rain covers induce a reduction of phytosanitary products use and tractor operations. However

the GHG benefits from these input reductions are outbalanced by the 10% yield reduction

expected, and the rain-cover installation operation. At the product level, the yield reduction

cancels all the benefit from the rain covers and leads to a 15% climate change increase. The

hypothesis of 10% yield reduction needs to be confirmed in the coming years. Also rain cover

could maybe be improved in order to lower the yield losses. If the benefit is limited on climate

change impact, the rain-cover-option is interesting regarding ecotoxicity, as it reduces by more

than four times the impact. This situation perfectly highlights possible burden shifts.

The fixed spraying system reduces tractor operations in the orchard, limiting soil compaction risks.

This installation enables farmers to act immediately after rain episodes against fungal diseases for

more efficiency, save time and labor, and reduce exposure risks for workers. GHG reduction could

be further improved by using French grid electricity instead of a tractor to activate the compressor.

However, this solution does not reduce significantly phytosanitary product use, and has therefore

little effect on toxicity impacts. Nevertheless, the management system "fixed spraying" is still

interesting for both conventional and organic orchards.

Scab tolerant/resistant cultivars are the only solution raising positive gain in all impact categories,

thanks to a reduction of spraying operations (less tractor use) and less phytosanitary product use.

far it represents only 10% of the production. Consumer education could be useful to further

develop this solution, as those cultivars have different properties than conventional ones:

conservation, aspect, taste etc. Also consumers tend to be more receptive to organic or zero

pesticide approach than a reduction (even if it is a large one). In any case, this is a promising

MATERIAL AND METHODS

LCIs for national average apple were calculated in AGRIBALYSE 1. The results were presented

to a group of experts in apple production (growers, technicians and scientists). GHG emissions

hotspots were discussed and experts proposed some options to reduce environmental impacts,

based on technics developed in research centers or tested in innovative farms. These solutions

were incorporated within crop management system then assessed through LCA, always

following AGRIBALYSE methodology (Koch and Salou, 2016) and using Means tool (INRA,

2017) .

Five new management systems were studied :

- 1. Scab tolerant varieties

- 2. Rain cover

- 3. Fixed spraying system

- 4. Electric self-propelled platform

Conclusion

This preliminary work opens interesting perspective to improve apple environmental footprint. In the future, new farming technics will be available to the farmers, e.g. for pest

management, water use or tree fertilizing. Proving their efficiency will require sound environmental assessment. Also, taking into account wood carbon storage and grass strip

s soil carbon in the footprint could highlight new options and encourage producers to change the orchard's end of life management.

Finally, eco-design for fresh fruits and groceries should not only consider the farm stage, but also include post-harvesting operations like fruit storage, packaging or logistic, as

they unite a big share of environmental footprints of these products.

Scab tolerant varieties : Scab is the most common apple tree disease. This cultivar choice

reduces the number of fungicides : nine spraying and tractor operations less compared to

conventional varieties.

Rain cover : Rain cover protection allows tu reduce the risk of scab development and therefore

the number of fungicides treatments. Seven years life span was considered for the rain covers,

requiring changing once the equipment during the orchard life time. The reduction of light due to

the rain cover was taken into account, inducing a 10 % yield réduction. Additional irrigation was

also considered, in particular in the spring season.
