2.2 وصف تفصيلي للتقنية

الوصف:

In response to changing environmental conditions, it can be valuable to adopt new plant varieties that offer benefits such as drought tolerance. The key is the improved adaptation of the crops to heat and drought. These adaptations are based on plant physiological and morphological characteristics that confer increased drought tolerance, as well as phenology, which can also affect the plants' water requirements. The goal is to reduce production losses and promote a regional, plant-based food system in Switzerland. To introduce and maintain drought-resistant crops requires specific activities and inputs, such as selecting suitable seeds and ensuring long-term profitable cultivation. This technology is applied to cropland in Switzerland, especially in the Swiss Plateau, where climate change is causing increasingly warmer and drier summers, as well as more intense precipitation in the winter months. These climatic changes favour the cultivation of crops that can better cope with drought periods, allowing for the replacement of crops that require irrigation in the same growing areas.
The main purpose is to adapt agricultural production to the effects of climate change while simultaneously reducing the emissions caused by farming. By cultivating drought-resistant crops, the risk of production losses during drought periods can be minimized, and a transformation towards more diverse, plant-based, and regional food production systems can be promoted. A major advantage of this technology lies in the adaptability of the selected crops to climate change. Since they are better adapted to tolerating drought periods, no additional irrigation is needed: this saves labour and other resources. Moreover, growing drought tolerant crops enables the production of regional, plant-based, and protein-rich foods (especially legumes) that are appreciated by certain consumer groups and can be better marketed.
However, there are also challenges and disadvantages that are not yet appreciated by land users. The lack of knowledge about non-traditional crops in Switzerland is a significant problem. Both theoretical knowledge and practical experience in cultivation are lacking, leading to high risk for farmers who must experiment with cultivation. Additionally, despite climate scenarios predicting drier summers, there is still the risk of cool and wet summers with increased precipitation. Besides the biophysical challenges, there are also socio-economic obstacles, as the demand from wholesalers is often focused on traditional crops, and niche crops like millet are commonly not popular.
This documentation focuses on an example of an innovative farmer in Spins, Switzerland. Stefan Brunner has been testing a wide variety of drought-resistant legumes such as lentils, lupins and black runner beans on his Eichhof farm since 2017. In addition to the large-scale cultivation of these drought-resistant crops, he also cultivates quinoa, peanuts, chia, sorghum, millet and rice in a demonstration plot. Stefan Brunner simultaneously attaches great importance to sustainable cultivation methods which include surface tillage and mulching.

3.7 الأنواع الرئيسية من تدهور الأراضي التي تناولتها التقنية

التعليقات:

Brunner sees soil degradation as an unavoidable consequence of all agricultural tillage. However, this can vary greatly depending on the type of tillage. Brunner does not see a direct improvement in soil degradation through the cultivation of drought-resistant plants. However, in combination with soil-conserving forms of cultivation. Brunner attaches particular importance to shallow tillage (maximum depth of 5 cm). Accordingly, crops that can be sown at this depth are suitable. Brunner strives for permanent rooting of the soil and prefers crops that can be sown in the fall so that the soil is rooted over the winter or can handle green manure. These measures (shallow cultivation and root penetration) keep the soil looser. The roots form flow paths, which increases the water storage capacity of the soil. The shallow tillage with small machines, which Brunner uses for his drought resistent crops, also reduces the physical pressure on the soil compaction.

7.	After 6-7 weeks, the green manure is worked back into the soil. When the plants are still young, they have the highest nutrient input before they extract the nutrients from the soil again if they continue to grow. As a result, the nutrients are mineral-bound in the soil, i.e. stored so that they are available to the plants.	autumn (early/mid-September)
8.	Another green manure is sown, which produces a lot of mass but freezes off in winter before it starts to flower. The aim is to keep the soil covered and rooted throughout the winter.	autumn
9.	In spring, the soil is again worked shallowly. This means a maximum depth of 3-4 cm. The winter green manure is "planed". This means cutting it to a depth of 3-4 cm and leaving the plant material on the ground.	spring
10.	The lupins are sown under the plant material to a depth of 4-5 cm, so that the soil remains moist and the plant material protects the soil from drying out.	spring (beginning of March/April)

التعليقات:

The first three information does not refer to a specific crop, but describes general maintenance activities that Brunner takes into account when cultivating his crops.
Stefan Brunner's crop rotation also includes 3 years of grassland. This cultivation reduces the workload, as no maintenance work has to be taken into account in addition to the harvest.

The activities 4-10 described relate to the cultivation of lupins. This crop was cultivated at the time of documentation in spring 2024.

22575,0

التعليقات:

The costs of cultivating drought-resistant plants cannot be precisely quantified. Based on the interview results, it is therefore not possible to make any general statements about the costs of cultivation.

Nevertheless, in order to be able to make a rough estimate of the input costs required to implement the technology (Example based on the cultivation of lupins), information from REFLEX 2024 (AGRIDEA's business database) and FiBL (Research Institute of Organic Agriculture) was used. According to REFLEX 2024, the target price for lupins in 2023 and 2024 is 144Fr./dt. A FiBL leaflet also states a requirement of 130-170kg seed/ha (blue lupins).

According to the results collected, the documented farm uses a disk coulter seed drill with a row spacing of 12.5 cm, sows approx. 3-4 cm deep and requires 200 kg/ha of seed.

With a field size of the documented farm of approx. 2 ha, the costs for the required lupin seed amount to CHF 576 according to the data from REFLEX 2024.

Then there are the labor costs and the machines. Depending on which machines are required and whether the required machines are already available or whether a new investment or rental would be necessary.

The estimate only refers to the seed required. Additional recurring costs include maintenance/ rental costs for machinery and labour. Unfortunately, it is not possible to provide more precise information on this. It depends on the machines and labor costs used.
However, according to the interview results with a farmer who grows drought-resistant crops, there are no significant additional costs if the drought-resistant crops can be grown with the same machinery as for conventional crops.

4.7 أهم العوامل المؤثرة على التكاليف

قدم وصفا لأهم العوامل التي تؤثر على التكاليف:

The greatest difficulty in terms of costs lies in the lack of knowledge in the cultivation of these crops. The fact that very little scientific and practical knowledge and experience is available means that farmers take a greater risk in cultivating these crops. If cultivation is not carried out correctly and the farmer suffers production losses as a result, he bears the consequences. This is why they have to look for inventive solutions.

6.4 تحليل التكلفة والعائد

كيف تتم مقارنة العوائدمع كلفة الصيانة/التكاليف المتكررة (من وجهة نظر مستخدمي الأراضي)؟

التعليقات:

The more equipment has to be used in cultivation, the more expensive the maintenance costs become. As Brunner is able to cultivate drought-resistant crops such as lupins and lentils with the existing equipment, he did not incur any additional costs. Even if a new machine for gentle soil cultivation in the cultivation of drought-resistant crops, such as a “planer”, had to be purchased, a plow could be sold in return. As long as the same mechanization can be used as Brunner was already using for conventional crops, the costs remain the same. As a result, Brunner's cost-benefit ratio was assessed as positive, even in the short term.
In the long term (over a period of 10 years), Brunner also sees an increased positive cost/benefit ratio. Consistently good soil cultivation regenerates the soil so well that it is able to absorb much more water. The amount of work required to implement this form of cultivation increases in the short term. However, the improved soil conditions in connection with the cultivation of drought-resistant crops have a positive effect on the workload and yield in the long term, as the crops on healthy soil are more flexible in the face of extreme weather conditions such as increasingly frequent droughts. Brunner also emphasizes that, from his perspective, it is worth incurring higher start-up costs for careful cultivation in order to generate long-term benefits.
The start-up costs are often relatively high, but the long-term benefits are all the more valuable. Start-up capital is therefore essential to be able to generate long-term benefits.

6.7 نقاط القوة / المزايا / الفرص التي توفرها التقنية

نقاط القوة/ المزايا/ الفرص من وجهة نظر مستخدمي الأراضي
No Irrigation Needed: These crops do not require irrigation, thus saving water and reducing labor.
Promotion of Soil Health: The cultivation of these crops is beneficial for the soil, as as the tillage is shallow and legumes do not require additional nutrient inputs through fertilization.
Benefits in Direct Marketing: These crops are niche products produced in limited quantities in Switzerland. Conscious consumers who value regional food products appreciate these items and understand the higher costs due to the high labor requirements.

نقاط القوة/ المزايا/ الفرص من وجهة نظر جامع المعلومات أو غيره من الاشخاص الرئيسيين لمصدر المعلومات
Reduced Irrigation Needs: If the crops can tolerate more drought, less irrigation is needed.
Minimized Economic Risk: Drought tolerance reduces the risk of crop failure during dry periods.
Crop Rotation Benefits: Better adaptation through diverse crop cultivation.

6.8 نقاط ضعف / مساوىء / مخاطر التقنية وسبل التغلب عليها

نقاط الضعف/ المساوىء/ المخاطر من وجهة نظر مستخدم الأراضي	كيف يمكن التغلب عليها؟
High Labour Requirements: initial labour requirements are significantly higher due to limited knowledge and practical experience in cultivation, but with time this reduces - as less and less work is required on healthy and nutrient rich soils.	More practical knowledge should be gathered by encouraging more farmers to cultivate these crops and facilitating knowledge exchange.
Lack of Mechanization: Available market machines are not suited for the desired cultivation methods.	Alternative machines are needed, which are smaller and lighter and only minimally till the soil. New approaches and inventions in machinery are required.
The wholesale market is not particularly interested in domestically produced alternative foods. Wholesalers are profit-oriented and primarily offer what is consumed in Switzerland.	A reorientation of dietary habits is necessary. Millet, for example, is ideally suited to the climatic conditions in the Seeland region. Increased consumption could lead to more extensive cultivation.

نقاط الضعف/ المساوىء/ المخاطر من وجهة نظر جامع المعلومات أو غيره من الاشخاص الرئيسيين لمصدر المعلومات	كيف يمكن التغلب عليها؟
Lack of knowledge: limited knowledge and practical experience in cultivation	More research should be carried out in this area and practical experience in cultivation should be gained through practical implementation. Inovative farmers are in demand.
Weather Variability: There is no guarantee that heavy rains won't occur, potentially ruining the harvest.	The extent to which crops are affected by severe weather events depends on when they occur. Severe weather events have an impact on every crop, but of course you don't know when they will occur. A useful strategy is therefore to build a highly diverse production system at farm and landscape level.
Practical and Socioeconomic Challenges: Market preferences and practical issues, such as livestock not favoring sorghum feed, can be obstacles.	No answer given.
