It is now widely recognized that agroforestry can make a significant contribution to the design of sustainable land management. However, support for agroforestry systems within the framework of agricultural subsidies in Germany is still not enough. For this reason, the professional associations Arbeitsgemeinschaft bäuerliche Landwirtschaft e.V. (AbL) and Bund Ökologische Lebensmittelwirtschaft e.V. (BÖLW), together with the Deutscher Fachverband für Agroforstwirtschaft e.V. (German Association for Agroforestry), have written an open letter to the ministers and senators for agriculture and the environment of the federal and state governments. With a total of 99 co-signing associations and institutions, the letter shows broad agreement with the demands formulated in the letter, which relate, among other things, to the currently existing bureaucratic hurdles such as the utilization concept and distance regulations.

With an intense smell of rapeseed in the air and a skylark concert, we were active in spring sunshine on the land of farmer Marion Herrmann in Sieglitz near Lommatzsch to rid some trees of weeds in the agroforestry system planted before Easter.
Five parallel strips were planted, each consisting of five rows of trees. The outer two strips were planted with four different performance varieties, which are now being analyzed in the growth process. The varieties planted were "Vesten" (Populus deltoides x P. nigra), "Bakan" (P. trichocarpa x P. maximowiczii), "Dender" (P. deltoides x (P. trichocarpa x P. maximowiczii) and "Matrix 11" (P. maximowiczii x P. trichocarpa). These fast-growing tree stands can be used for regional energy as well as raw material production after a several years growing season. The middle single strip was planted with wild cherry/bird cherry (Prunus avium ssp. avium), Norway maple (Acer platanoides), and littleleaf linden (Tilia cordata). These deciduous hardwoods are used for long-term cultivation for the production of valuable timber, which can be sold to the timber industry as veneer or solid wood after about 40-60 years.
The task in this work assignment was to clear the value timber stands of regrown weeds around the plantings. Removing them by hand with a hoe was a tough job in the dry clay soil, but with combined efforts it went faster than expected! Probably there will be a second weed control action in spring, after that it will be no longer necessary and the trees are big enough.
Thanks to the organizers BUND Dresden and Landwirtschaftsbetrieb Herrmann! We were glad to be there!
There are trees on the fields of the Lommatzscher Pflege (again) - at least they are initially rods, which should already be small trees in the fall. One farm in Sieglitz near Lommatzsch has opted for an agroforestry system on its land. And this is just the beginning! OLGA, in cooperation with farmer Marion Herrmann, the Stadt-Land-Plus 'sister project' WertVoll, the biotope network project of BUND Dresden, and the agroforestry or permaculture experts for fast-growing tree species Lignovis GmbH and Nam Nam Natura, has made short work of creating the foundations for an agroforestry system with energy and value woods.
The agroforestry plantation in Sieglitz involves five parallel strips, each consisting of five rows of trees. The outer two strips were planted with four different performance varieties, which are now being analyzed in the growth process. The varieties planted were "Vesten" (Populus deltoides x P. nigra), "Bakan" (P. trichocarpa x P. maximowiczii), "Dender" (P. deltoides x P. trichocarpa x P. maximowiczii) and "Matrix 11" (P. maximowiczii x P. trichocarpa). These fast-growing tree stands can be used for regional energy as well as raw material production after a short multi-year growing season. The middle single strip was planted with wild cherry/bird cherry (Prunus avium ssp. avium), Norway maple (Acer platanoides), and littleleaf linden (Tilia cordata). These deciduous hardwoods are used for long-term cultivation for the production of valuable timber, which can be sold to the timber industry as veneers or solid wood after about 40-60 years.
This agroforestry crop was planted with a strip spacing of 72 m in a north-south orientation in order to significantly reduce wind erosion, improve the water balance, keep the shadows cast on the arable crops low and at the same time secure the yield in the crop rotation, especially in dry years. Wood production creates another branch of the business, which improves the diversification of the farm. This is a successful example of the connection of biodiversity and utilization for a new green network to be created & structural improvement with the farmers. This cultural landscape development voluntarily links agriculture with applied, production-integrated conservation - a good way to go.
We will continue to follow the development of the system and communicate the benefits of agroforestry use in Saxony in cooperation with all stakeholders - for example, by showing other farmers on site in Sieglitz how it can be done. We are staying tuned!

Ab sofort können Interessierte an einer Online-Umfrage zur Bewerbung Dresdens für die Bundesgartenschau (BUGA) 2033 teilnehmen. Akteure, Institutionen sowie Bürgerinnen und Bürger sind eingeladen, bis Sonntag, 23. April 2023, Rückmeldungen zu einer ersten Ideenskizze zu geben sowie eigene Wünsche und Vorstellungen einzubringen.
Das Zentrum für Angewandte Forschung & Technologie an der Hochschule für Technik und Wirtschaft Dresden schreibt eine Stelle in Vollzeit (40 h/Woche, 100%) oder in Teilzeit für das Bündnis DMPL (Diversitäts-Management und neue Prozessqualität für nachhaltige Landwirtschaft und regionale Wertschöpfung) aus. DMPL etabliert ein nachhaltiges Netzwerk von Akteuren entlang landwirtschaftlicher Wertschöpfungsketten und entwickelt dabei ein neuartiges Management in Bezug auf Strategieentwicklung, Innovationsförderung und Projektbegleitung.
Both organic and conventional farms can now apply to participate in the LeguNet project at the Saxon State Office for Environment, Agriculture and Geology. By participating, you agree to take on the demonstration cultivation of a grain legume and to deal with technical production issues. The aim is to optimise your own cultivation method and to impart knowledge on the subject. Experienced and interested farms in legume cultivation thus benefit directly from the specific expertise of other farms. The website www.legunet.de already provides information about the project and the cultivation of legumes.
LeguNet is the "model demonstration network for expanding and improving the cultivation and utilisation of grain legumes in Germany". It combines three previous networks on pea/bean, soya and lupine of the nationwide protein crop strategy. The aim is to increase the cultivation and utilisation of legumes in Germany. In particular, the focus is on processing and marketing of field bean, pea, soya and lupin. Still rare but increasingly interesting species such as chickpea or lentil are also considered.

The COSMO Science Forum invites you to the launch event of the new exhibition on the topic of "What is Sustainability?" on 15th of March at 17:00.
What does climate change mean for us locally? Are our trees in the forests and parks dying now?
Sustainable food for all - is that even possible? How can we bring together efficient food production and a healthy ecosystem?
How do we want to change our cities? Can they become more environmentally friendly and at the same time more equitable?
In short, how can we make our way of life sustainable and more liveable?
Scientists from Dresden, including those involved in the OLGA project, have been researching the topic of sustainability for years and are now using more than ten exhibits to show possible solutions to these and other pressing questions of our time at the COSMO Science Forum from mid-March to mid-July. The topics range from biodiversity, climate change and environmental protection to recycling, sustainable urban development and education to agriculture and nutrition. In addition to vivid models, interactive virtual reality installations and displays as well as videos will be on show. The exhibition will be accompanied by a variety of events over the coming months.
The opening event on 15th March 2023 at 17:00 will kick things off and all interested people are cordially invited to attend.

As part of the analysis of the microclimatic effects of agroforestry structures on neighbouring watercourses, we have also worked in OLGA on monitoring the habitat change of microorganisms in the watercourse - the so-called macrozoobenthos. At the end of 2022, a scientific article entitled "Development of transient habitat modelling for stream macrozoobenthos" was published in English at the Institute of Hydraulic Engineering and Technical Hydromechanics at TU Dresden.
The BUND Regional Group Dresden is carrying out the project Multifunctional Biotope Network (in German) until June 2023. An agroforestry strip is to be established at the edge of watercourses in the surrounding area of Dresden (neighbouring districts). For this measure, the project is still looking for a farmer who is interested in establishing a pilot site.

For the period 2023-2024, the KOPOS project is looking for one model project in each of the Berlin-Brandenburg and Freiburg im Breisgau regions that will use a sustainable approach to practically test concepts for a sustainable and regional food supply based on principles of cooperation. The best project idea in each region will be awarded 100,000 euros.
The funding programme Stadt-Land-Plus, in which the OLGA project also runs, reports in its 13th newsletter on the news from the individual project clusters and the world of settlement, land and rural development & regional value creation in urban and rural areas.

With its small project fund, the Bio Planète Ölmühle Moog GmbH wants to promote innovative and sustainable action for healthy soils, biodiversity and sustainable agriculture. Projects up to a maximum of € 10,000 and with an implementation between autumn 2022 and the end of 2023 are supported.
After three years of Corona online meetings, all participants were finally able to meet and exchange ideas in person at the Felsenkeller in Leipzig on the 19th and 20th of September 2022. At the "Marketplace of Opportunities", all initiatives presented themselves, shared their results and synergies. There were also one or two good tips for the OLGA team. For example, in some federal states agroforestry systems can be implemented as a production-integrated compensation measure. Maybe also an option for Saxony?! One stand showed the steps needed to produce activated carbon pellets from green and landscape cuttings. That can also be done with agriwood, can't it? From other projects we learned how to carry out agricultural reallabs or how "tiny gardens" look like.
For the continuation of processes, cooperations and reallabs etc. in cities and regions, it is important to think about legal regulations, planning guidelines and horizons, and to find people who think regionally and are committed to their topics and projects beyond the boundaries of municipal or city administrations. During the implementation phase of OLGA, we will make sure to have a regular exchange with actors in Dresden and the surrounding area so that our pilot measures and agricultural reallabs can be continued.
Field trip about regional food value chains in the Leipzig region
On the second conference day there were four thematic excursions to choose from. We took the one dealing with regional products - of course - and spoke to people who are committed to regional food value creation in Leipzig and the surrounding area:
Thilo Egenberger sells mostly regional and organic food in the Plagwitz market hall - this is also where the refreshingly sour "lipz Schorle" was created. The City of Leipzig is currently developing a comprehensive cross-sector strategy for regionally sustainable food. Lots of municipal instruments are involved in this process, such as studies, leasing criteria, regional marketing, nutrition education, etc.
Johanna and Robert at the Lerchenhof in Jesewitz gave us an insight into a regenerative farm. Soon they will start up an organic mill for processing regional cereals and legumes (!). Lastly, we stopped at Wassergut Canitz GmbH to see an example of a valuable urban-rural cooperation for the production, processing and marketing of regional organic food (potato and onion!) in the drinking water protection area of Leipzig.
Four municipalities in the Wurzen region want to promote regional material and product cycles. To this end, they founded the Wurzener Landwerke. Here, four inter-municipal companies have already been established for the tasks of digitalisation, energy, service and regional food.
Thank you to the WERTvoll project team for organising the excursion and to all the speakers! It was great fun with you!
Regional legumes as vegetable protein suppliers are a key component for climate-friendly nutrition and agriculture. On 5th of October 2022 from 13:30-17:30, the association Nahhaft e.V. and the OLGA project are offering a workshop for catering managers in school and daycare canteens in the Dresden region.
This year we were part of this year's Kraftwerk Mitte Fest, the cultural festival in the centre of Dresden. With a joint stand with Europe Direct Dresden and Europa-Union Sachsen, two initiatives that are also based at the Umweltzentrum, we specialised in the topic of pulses at this festival, because we want more people in Dresden and the region to realise that peas, beans, lupins, lentils & co. are tasty, contribute to a healthy diet and protect the climate.
At our stand, many people learned about the use of pulses and took away great recipe ideas for pea guacamole or field bean brownies, for example. We immediately offered the brownies for tasting, which were especially popular with the children compared to the soy and lupine tempeh samples we offered on behalf of Umani Kulturgut from Leipzig. It was rather the adults who stayed there and marvelled: that doesn't taste bad at all. The interest in pulses as a protein supplier and meat-free alternative in human nutrition is also growing in Dresden. We are happy!

The OLGA test area at farmer Thomas Domin's in Peickwitz in southern Brandenburg became the setting for a mdr feature on agroforestry this summer. Manuel Wewer from the Institute of Hydraulic Engineering and Thermal Hydromechanics at the TU Dresden explains from minute 6:20 the technology installed in and around the Peickwitz millrace to measure water temperature, water level, air temperature, humidity and pressure as well as wind speed and solar radiation. The measurement results provide information about the shading effect of the adjacent agricultural wood structure on the watercourse.
It has been talked about for a long time, now at the end of June it came to the first "Come Together": Stakeholders from the City of Dresden and the TU Dresden met at the latter for the workshop "What's sustainable in Dresden?" as part of the TUD Sustainability Week. The meeting was organised by the Green Office of TU Dresden and Zukunftsstadt Dresden, which has been funded by the Federal Ministry of Education and Research since 2015 and has so far produced a number of sustainable citizens' projects and initiatives. During the moderated exchange over coffee and cake, a number of synergies between TU institutions and the municipal departments emerged with regard to the sustainable development of Dresden and the overall social transformation in the city. Although both institutions have already worked together on individual projects in the past, the need for stronger and more permanent cooperation was felt again and again. Topics that were addressed in this context and could play a role in the future between science and administration were:
- Climate-neutral and smart city 2030
- Consideration of climate protection in the renovation of buildings, e.g. vegetation and photovoltaics on roofs
- Sustainable equipment for events
- Knowledge transfer in the development of sustainability strategies and integrated climate protection concepts
- Inclusion and participation
- Regional and climate-adapted agriculture and food system
- Education for sustainable development
- Protection of biodiversity and development of urban nature
OLGA was also present at the exchange. We made contacts to promote research and development on sustainable approaches to land management and food habits (regional, seasonal, climate-adapted!) in the region and to raise awareness for regional value creation in agriculture and food in general. At TU Dresden, there are already initiatives in this regard for more regional communal catering in the TU canteens and the stronger integration of educational offers for sustainable development in the area of agriculture and nutrition for students, e.g. directly on a campus-owned agricultural practice and experimentation area. All participating projects and initiatives were able to present themselves in the form of a project stand. We didn't need to be told twice and turned our OLGA info point into a tasting stand for mini-breads made from regional field bean flour with at least locally prepared field bean and lupine hummus with lots of information about the nutritional value and the climate balance of pulses for the stand visitors.
The networking process between administration and science will already be continued beginning of September at a second "sustainability" meeting.
The Südpark area in Dresden is currently being developed into a landscape park with multifunctional use (agriculture, nature conservation, leisure, meeting places, gardening, etc.). It is to become a park for the people living here. Since we in OLGA are concerned with sustainable land use and food production, processing and consumption in urban and rural spaces, we are of course also interested in a sensible agricultural use of the park.
We used our team meeting today to make a site visit by bike to Südhöhe to see what can happen there in the next years. There are a few ideas for land use on the slightly sloping site. An urban farming concept with cooperation partners seems most attractive to us at the moment. Currently, the agricultural land designated by the development plan is just maize. We will make sure that the land use will get more multifunctional, diverse and colourful up there in the future. So stay tuned for what we will come up with to make urban agriculture tangible and communicable!
Das Bundesministerium für Ernährung und Landwirtschaft (BMEL) beabsichtigt, Modell- und Demonstrationsvorhaben (MuD) im Rahmen eines Aufrufs zum Thema „Zukunftsfähige Landwirtschaft mit Agroforstsystemen“ zu fördern. Die Förderung erfolgt über das Förderprogramm „Nachwachsende Rohstoffe“ (FPNR) und untersetzt den Förderschwerpunkt „Entwicklung von Konzepten für eine nachhaltige Erzeugung und Verwertung nachwachsender Rohstoffe unter besonderer Berücksichtigung der Ressource Wasser“.
Within the framework of the Agroforestry Academy initiated by German Association for Agroforestry (DeFAF), extensive further training courses on agroforestry are taking place for the first time this year. The new website of the Agroforestry Academy is now online and provides information on the background and offers of the Academy. For the time being, two courses will be held this year: an agroforestry practical course for agricultural practitioners and an agroforestry planning course for advisors from the agricultural sector. It is planned to hold the courses annually. Up-to-date information will be available on the new website of the Agroforestry Academy. If you are already interested in participating in one of the two courses next year, you can contact the Agroforestry Academy team directly: www.agroforst-akademie.de (in German)
Food systems must ensure a balanced diet for all people. But how can we produce food in an environmentally and socially responsible way? What developments and innovations does the future hold? This is what the National Dialogue is about.

Solidarity Farming (SoLawi) is an innovative model for a sustainable, regional food supply. While consumers are supplied with good food all year round, this type of producer-consumer community provides agricultural businesses with planning security and fair wages.
Agraset Agrargenossenschaft eG in Saxony shares this view, which is why it would like to transfer land to a SoLawi. For this, committed gardeners and consumers are needed to promote the establishment of a SoLawi on this land. All interested parties are invited to an information event on 27th of April 2022 in Erlau.

Have you heard the podcast "Knowledge for Future"? Our colleagues from the Stadt-Land-Plus-project KOPOS work together with detektor.fm and look at smart ideas that could make the world a little better. How can it be financed? And how can politics take a sustainable path into the future? One focus is of course on the food revolution, how we can produce and consume more sustainably and regionally.
Also in 2022 the "eku - Zukunftspreis für Energie, Klima, Umwelt" is going into the 3rd round! With this prize, the Saxon State Ministry for Energy, Climate Protection, Environment and Agriculture (SMEKUL) would like to support and make visible Saxony's commitment to the transformation towards a sustainable and climate-neutral society.
Entrepreneurs, scientists, municipalities, committed civil society and especially children and young people can participate. Applications with project ideas and/or successfully implemented projects can be submitted online from today until 28th of April 2022.
This year, for the first time, DeFAF e.V. is offering a comprehensive training course on agroforestry for farmers and advisors. The two-year courses will take place within the framework of the Agroforestry Academy, which is to be developed in the long term as a recognised training centre for topics related to agroforestry. Registration for the courses is possible from 7th of February 2022.

2023-2027, a total of € 718 million will flow into Saxon agriculture, of which the Free State will co-finance around € 100 million. Planning security, income prospects, transformation and greening are central aspects of future agriculture in Saxony.
In doing so, the partners will jointly explore new ways of local cooperation between science and practice. This is the aim of the cooperation agreement signed by Marc Wolfram, Director of the IOER, and Mayor Dirk Hilbert on Monday, 6 December 2021.
The IOER and the City of Dresden are already working together in various projects on sustainable urban and regional development. Among other things, they are working on heat adaptation in densely built-up urban districts or the participatory design of processes of sustainable innovation. In the future, the partners want to orient themselves even more long-term and coordinate more strategically than before.
The agreement aims at a new form and quality of local cooperation between science and practice. The aim is to take up and link different bodies of knowledge from politics, administration, business, science and civil society and make them equally useful for research and practice. The newly acquired knowledge should help to initiate, accelerate and perpetuate innovative processes and thus drive a profound change towards sustainability.
OLGA will actively contribute to the cooperation process with the strategies and implementation options for sustainable land use in Dresden and the surrounding area as well as a more regionalized agriculture and food economy in the region.
At the OLGA partner meeting in autumnal Tharandt, we were creative: we painted, cut and pasted for all we were worth. The goal: What optimal land use do you imagine? Admire the selection of exhibits that were created.
Of course, we also worked on the side and discussed possible forms of planting and managing agricultural wood and sounded out the need for cooperation and communication in this regard. Possible "real laboratories" for the OLGA implementation phase are successively figured out.
We also gained an insight into the laboratory work of the woody plant physiology research group and learned how roots of poplar clones are scanned and then analysed, for example, in terms of their length and volume. In doing so, conclusions can be drawn about root growth under certain conditions within the first 60 days after the cutting is placed in the ground. We were also instructed in the software in which the terrestrial laser scanning of the agricultural wood study plots in Klingenberg-Colmnitz and Peickwitz is analysed and modelled.
The online panel discussion of 9th September 2021 is now also available on Youtube (in German):
Europa am Morgen #5: Der Green Deal und die sächsische Landwirtschaft
The regional supply of food has long been an important part of urban-rural relations in Europe. However, due to the globalisation of agricultural systems, cities are hardly fed from their surrounding countryside anymore. In addition, biodiversity in our landscapes is declining enormously, for which agriculture is seen as the main culprit. Also in Saxony. So how do we get back to regional cycles, to more nature and diversity in agriculture? The European Green Deal adopted by the EU promises a turnaround back to regional production and food systems and a stronger integration of nature conservation and agriculture. In our online discussion, we examine the package of measures for its potential to strengthen regional value-added structures, forms of sustainable land use and ultimately regional cooperation between urban and rural areas. In doing so, we explicitly take a look at the situation in Saxony.
On the podium:
Robert Gampfer is responsible for climate and environmental policy at the EU Commission Representation in Germany.
Bernd Laqua is mayor of the municipality of Bennewitz in the Wurzener Land. The non-party mayor is in office in his second term until 2027.
The event was supported by the projects WertVoll and OLGA.
For the annual Stadt-Land-Plus status conference, where all funded projects report on their activities, progress and challenges, we created a video pitch. Here you can see the result:
Since May 2021, the TU Dresden has been running measurement campaigns on the watercourses and in the agricultural wood structures in Peickwitz, Klingenberg-Colmnitz and on the Mortelbach near Waldheim. In two rounds (vegetation period 2021 and 2022), different parameters will be investigated that describe the functions and services of agricultural wood structures for the flowing water ecosystem.
At the Peickwitz site near Senftenberg, an agricultural wood plantation with the poplar species Fritzi Pauley was planted along the Peickwitz millrace to reduce wind erosion. Directly adjacent to the Wiesengrundbach in Klingenberg-Colmnitz is a 0.8 ha agrowood plantation (a so-called variety garden with poplar and willow trees), which is used as the second pilot area in the measurement campaign.
The following parameters are included in the analyses:
- Water level h [m].
- Flow velocity v [m/s]
- Flow rate Q [m³/s]
- Water temperature T [°C]
- Terrain [m a.s.l.]
- Location of woody plants
- Air temperature and humidity
- Soil water content
- Radiant heat of the sun
- Circumference of tree trunks
- Leaf sprouting and leaf fall
- Leaf area index
- Tree structure (laser scan 2x per year)
- Vegetation development
- Soil properties
- Wind speed
- Solar radiation
- Air pressure
In addition, the team from the Department of Hydraulic Engineering at the TU Dresden is conducting macrozoobenthos (microorganisms in flowing water) sampling on the Mortelbach in the district of Mittelsachen in order to be able to make statements about water quality and temperature development.
As soon as the first results and series of measurements are available, we will publish them on this website.
The OLGA project meeting on 14th of July 2021 took place on Thomas Domin's farm in Peickwitz near Senftenberg. In the morning, we visited the agroforestry areas and talked about the diverse ecosystem services that an agroforestry system can provide when appropriately designed. The rows of fast-growing woody plants here in Peickwitz were planted primarily because of the locally prevailing wind erosion. Poplar, willow & co. are lined up in alternation with cereals such as teff or rye. They protect the soil from erosion, bind carbon and can serve for the production of wood biomass and fruits (e.g. rock pear or chestnut). There was also a lot of talk about new marketing strategies that take more account of the land use concept of agroforestry and communicate it to society, such as through "agroforestry eggs", etc.
Likewise, the measuring installations on the OLGA agroforestry trial area along the Peickwitzer Mühlgraben were inspected and the first results of the temperature, precipitation and water flow measurements were looked at. At the end of the measurement series in 2023, they should provide information on the extent to which the woody plants contribute to the protection of the watercourse, e.g. in the form of shading and pollutant input reduction.
In the afternoon, the OLGA partners discussed the current status of the research work in the project. In addition to the first measurement results from the two trial areas, the results of the agricultural woodland potential analysis on watercourses for the Dresden region were evaluated. These will subsequently be further refined and, if necessary, extended to agricultural areas. Furthermore, the Citizen Science survey "How regional is your shopping?", which runs until 30.09.2021, and other participative events and measures in summer and autumn 2021 were introduced.
The Saxon Ministry for the Agriculture (SMEKUL) is currently setting up a centre of excellence for organic farming in Nossen (Saxony). For this purpose, the Ministry launched a participation process for practitioners of organic farming. Participation takes place via an online survey and anonymously via a so-called active box on the ministry's organic farming website. There, practitioners can rate and value the future research topics of the competence centre proposed on the website and add further topics. Participation is possible until 31 August 2021.
The Competence Centre for Organic Farming is currently being established at the Saxon State Office for the Environment and Geology (LfULG). Its work focuses on applied research, knowledge transfer and an impulse advisory service for existing or future agricultural enterprises involved in organic farming.
Within the framework of OLGA, Marie Herzig and Lena Schwarz, students of TU Dresden, determined the potential for agrowood to improve the ecological condition of smaller waterstreams in the City of Dresden and the surrounding districts.
In order to achieve the goals of the European Water Framework Directive, the significant reduction of substance inputs into watercourses is imperative. For the most part, such substance inputs are caused by erosion from intensively farmed areas. The establishment of agroforestry plantations as buffer strips between fields or grassland and watercourses can relieve the watercourses of substances and enhance the ecological value of the riparian zone. In addition, agroforestry plantations contribute to agricultural value creation.
The presented work serves as a first assessment of the area potentials for agricultural wood on arable land, grassland and brownfields in the Dresden region. After carrying out the analysis, 3,302 areas within the study area come into question for the establishment of agrowood plantations. These have a total area of 13,296 ha, which corresponds to a share of 9.6 % of the total grassland, arable land and fallow land in the study area. It is noticeable that most of the areas have the minimum size, i.e. they are rather small. On average, the area size is 4 ha, with the largest potential area being 33 ha.
Optimally, plantations should be established on special agricultural sites or fallow land so as not to compete with land used for food production. Moreover, agroforestry structures are a valuable climate adaptation measure to reduce increasing extreme events in the the Dresden region.
On 10 June 2021, the German Bundestag decided, based on an amendment, to include woody plantations on arable land AND on grassland in the funding. This is a decisive step that will make it easier for farmers to integrate more biodiversity-promoting and climate-adapted measures on their land. And the animals can look forward to more shade and less wind! We are also pleased about this decision.
A so-called Bio-Regio model region brings together actors from the fields of agriculture and food industry as well as regional development in order to implement individual concepts for regional value creation in their regions, preferably also with organic food, and to consolidate regional value chains for the benefit of all.
Within the framework of the 1st call for Bio-Regio model regions, suitable associations can apply with their individual concept. The best concepts will be selected by an expert committee under the leadership of the Saxon State Ministry for the Energy, Climate Protection, Environment and Agriculture (SMEKUL). The selected Bio-Regio model regions have the opportunity to apply for funding for their project through the AbsLE/2019 guideline (in German).

The "Bioeconomy model farms" ideas competition is looking for innovative and sustainable ideas for bio-based agriculture and forestry: from the production via the processing to the distribution of food, renewable raw materials and biogenic residues. Our goal is to strengthen value chains in the low mountain regions and to give new perspectives to the people who live and work here.
Individual agricultural and forestry enterprises can participate, but also associations of several enterprises or enterprises with crafts, trade, industry and science are permitted, as long as at least one agricultural or forestry partner is involved. Prize money totalling € 15,000 is up for grabs! Applications are possible until 31st August 2021.

Wintery hustle and bustle on an afternoon at the end of January: The OLGA project partners from Module 1: "Sustainable use of energy wood along watercourses and on agricultural land" met in Colmnitz to visit the 0.8 ha agricultural wood plantation on the Colmnitzbach, which was planted in 2007. The area is managed by the Colmnitz agricultural cooperative.
During the inspection, the members of the chairs of hydraulic engineering, forest botany and biodiversity and nature conservation at the TU Dresden discussed the suitability of the plantation as a experimental area, especially for modelling the effects of agricultural wood along watercourses on flood retention, aquatic habitats and on vegetation composition and phytodiversity. The agricultural wood plantation in Colmnitz would be the third experimental plot in the OLGA project.
The Saxon State Ministry for Energy, Climate Protection, Environment and Agriculture has launched the added value initiative "Sustainably out of the crisis". A total of 26.5 Mio € in funding is available for innovative projects for sustainable agriculture, forestry and fisheries, regional value creation, climate impact management and pioneering energy supply. Project applications can be submitted via an online portal until 31 March 2021.

Saxony presents a feasibility study on strengthening regional value creation and organic farming. The study concludes that there is a need for more networking between actors and less bureaucracy in terms of funding and start-up financing. A separate regional agency is to take care of these tasks in the future. It will serve as an instrument to improve value creation from production to processing to marketing and to increase sales.
We in the OLGA project are working towards the same goals in the Dresden region and have recognised that it is precisely this networking of actors and the development of joint cooperation structures that is needed so that small farms can continue to exist. Offering regionally sustainable products in the Dresden region and in Saxony should be a matter of course.
Press release (in German)
After an introductory speed-dating on project-relevant issues, the project partners reported on their work in the individual fields of action. A trial area was acquired in Peickwitz near Senftenberg to investigate the ecosystem services of agrowood plantations. Another trial area will be visited in January 2021 in the Tharandt Forest. At the "Mortelbach" trial site near Waldheim in Central Saxony, further 3D laser scans will be implemented at the beginning of the year to analyse the structure of the wooden structures near the river banks.
In spring 2021, plant physiological studies will be carried out on the agrowood plantation trial area in southern Brandenburg. Potential analyses for sustainable agriculture and energy wood cultivation in the Dresden region are going on. The results will be published here soon. The partners are preparing a public discussion event in Dresden on regional financing instruments and cooperation structures for mid-2021 with the hope of meeting there in an analogue format and thinking about sustainable city-regional solutions in the field of food in person. Networking with stakeholders and regional initiatives are currently in process.
The next OLGA network meeting will take place at the beginning of March 2021.
