Agricultores e técnicos envolvidos na citricultura orgânica procuram desenvolver sistemas de produção com maior atividade microbiana no solo. Dessa maneira, esperam obter benefícios dos processos que ocorrem no solo, entre eles, o controle natural de pragas e doenças. Porém, são poucos os estudos sobre a influência desse tipo de manejo sobre a microbiota do solo, em especial sobre os fungos micorrízicos arbusculares (FMAs) e o patógeno Phytophthora parasitica. Os objetivos dessa tese foram: avaliar a colonização micorrízica e conhecer a diversidade de FMAs nos sistemas de produção convencional e orgânico de citros; avaliar a aplicação de benomyl e da radiação γ na obtenção de testemunhas não micorrizadas para estudo de interação de comunidade de FMAs nativos e P. parasitica; verificar a capacidade indutora de resistência local e sistêmica dos FMAs nativos a P. parasitica; estudar atividade da quitinase no sistema radicular de limão 'Cravo' colonizado por fungos micorrízicos nativos. Foram realizadas amostragens em dois sistemas de produção de citros em São Paulo, um convencional e um orgânico. A riqueza e a diversidade de espécies de FMAs foram maiores no manejo orgânico. No entanto, a porcentagem de colonização micorrízica nas plantas no campo não variou com o tipo de manejo. Em casa de vegetação, experimentos com plantas de limão 'Cravo' (Citrus limonia) mostraram que a radiação γ foi mais adequada que a aplicação de benomyl na obtenção de testemunhas não micorrizadas para estudo de interação P. parasitica- FMAs nativos de agroecossistemas de produção de laranja. Também em casa de vegetação, foi realizado um experimento com raiz dividida de plantas de limão 'Cravo'. Não foi possível avaliar a capacidade indutora de resistência dos fungos micorrízicos arbusculares nativos porque não houve desenvolvimento da podridão de raízes nas plantas de limão 'Cravo' após a infestação com P. parasitica. Discute-se a interação de patógenos de raiz do solo natural e os FMAs nativos porque o solo natural dos sistemas de produção convencional e orgânico promoveram diferentes respostas de crescimento local e sistêmico das raízes das plantas micorrizadas. A atividade de quitinase foi igual nas raízes de plantas micorrizadas e não micorrrizadas cultivadas em solos dos sistemas de produção convencional e orgânico. Porém, a associação micorrízica aumentou localmente a proteína total nas raízes das plantas. / Farmers and technicians involved with organic citriculture try to develop systems with high microbial activity in soil. In this way, they expect to obtain benefits from processes that occur in soil, as natural control of pests and diseases. However, there are few studies about the influence of this type of management on soil microbiota, specially on the arbuscular mycorrhizal fungi (AMF) and the pathogen Phytophthora parasitica. The objectives of this thesis were: to evaluate mycorrhizal colonization and diversity of AMF in citrus conventional and organic farming; to evaluate benomyl application and γ radiation to obtain non-mycorrhizal controls for study of interaction between indigenous AMF and P. parasitica; to verify local and systemic capacity of indigenous AMF to induce resistance against P. parasitica; to study chitinase activity in roots of 'Rangpur' lime colonized by indigenous AMF. Samplings were carried out in two citrus systems in São Paulo, one conventional and one organic farming. The richness and the diversity of AMF species were higher in the organic farming. In greenhouse, experiments with 'Rangpur' lime (Citrus limonia) showed that γ radiation was better than benomyl to obtain non-mycorrhizal control for studies of interaction between P. parasitica-indigenous AMF from orange agroecosystems. In greenhouse also, a split root experiment with 'Rangpur' lime was carried out. It was not possible to evaluate the indigenous AMF capacity to induce resistance because no root rot developed in 'Rangpur' lime plants after inoculation with P. parasitica. We discuss the interaction between root pathogens in natural soil and indigenous AMF because natural soil from conventional e organic farming promoted different local and systemic root growth responses in mycorrhizal plants. Chitinase activity was similar in roots of mycorrhizal and non-mycorrhizal plants grown in conventional and organic farming soils. However, mycorhizal association increased local protein content in roots.

Despite phenomenal success of the commercial agricultural sector in South Africa and significant progress in integrating smallholders since democratic reforms, food security concerns remain. Recent global increases in food prices have further exacerbated vulnerabilities and made it imperative to examine alternative food production questions in the country. Organic agriculture is identified as one of the sustainable approaches to farming and offers insights towards a paradigm shift in food and nutritional security. Notwithstanding, consumer awareness, knowledge and consumption of organic foods are significantly lower in developing than developed countries. Risks associated with adoption of organic practices need to be explored to address the supply and demand constraints. Similarly, while consumer awareness of organic foods is the first step in developing demand for organic products, it does not necessarily translate to consumption. Therefore it is important to investigate these issues. The objectives of this study were to: (i) describe the demographic and socio-economic characteristics of organic farmers and consumers; (ii) establish the determinants of farmers‘ decision to participate in organic farming distinguishing between the fully-certified organic, partially-certified organic and non-organic farmers; (iii) elicit farmers risk preferences and empirically analyse farmers sources of risk and risk management strategies; (iv) explore consumer awareness, perceptions and attitudes regarding organic products; and (v) identify the factors that influence consumer‘s preference and consumption of organic products. A total of 400 respondents were surveyed, consisting of 200 smallholder farmers in KwaZulu-Natal and 200 consumers in the Eastern Cape. The KwaZulu-Natal study was conducted earlier and identified the following as major sources of risk, lack of consumer awareness of organic products and lack of information among producers about consumer preferences for organic products. This informed the need to undertake a consumer awareness and preference study, in order to inform producers. The Eastern Cape is a bordering province to KwaZulu-Natal with similar socio economic conditions and a major consumer of produce from KwaZulu-Natal. It was also expected that in the intervening period there could have been awareness about the product. An vii indication of its appeal would not be in the consumption of the product by the people who grow it, but by consumers who reside in bordering regions. Producer and household questionnaires were used to record household activities, socio-economic and institutional data as well as household demographics through personal interviews. The Arrow Pratt Absolute Risk Aversion (APARA) coefficient was used to measure the farmer‘s degree of risk aversion and the experimental gambling approach to establish the risk classification. Consumers were also asked about their awareness and knowledge about organics, attitudes and perceptions towards organics, preference and consumption patterns. The ordered probit results indicate that older farmers, who are less risk averse and reside in the sub-ward Ogagwini, Ezigani, and Hwayi were more likely to be certified organic farmers. Similarly, the propensity to adopt organic farming is positively correlated to household size, livestock ownership, asset base and tenure security. The risk analysis indicates that at higher pay-offs most farmers are intermediate to moderately risk-averse, with little variation according to personal characteristics, and that non-organic farmers tend to be more risk averse than fully-certified and partially-certified farmers. In general, price, production and financial risks were perceived as the most important sources of risk. Using Principal Component Analysis (PCA), seven principal components (PCs) explaining 66.13% of the variation were extracted. Socio economic factors having a significant effect on the various sources of risk are age, gender, education, location, information access and risk taking ability. The most important traditional risk management strategies used by the surveyed farmers are crop diversification, precautionary savings and participating in social networks. There was general awareness of what constituted organic foods with many consumers associating organic foods with health and nutrition, chemical free and produced using indigenous methods of production. However, there was low awareness of organic products among consumers with little or no knowledge of organic certification and standards. According to the logit model the major factors influencing consumer awareness of organic products are: gender, education, employment status, and location of the respondents, person/household member responsible for shopping and the price perception of the decision maker. The discriminant analysis showed that the consumption of organic products is significantly affected by age of the consumer, viii location, person/household member responsible for shopping, consumer awareness of organics, price perception and label trust. The findings from this study provides useful practical insights for policy makers, farm advisers and researchers in the design of effective and efficient policies, programmes and projects which can affect the adoption of organic practices, increase smallholder farmers capacity to manage risk and drive growth in the organic food market.

La productivité et la qualité des céréales biologiques sont soumises à deux principaux facteurs limitants dans les systèmes sans élevage : des déficits chroniques en azote (N) du sol et des infestations par les adventices. Des légumineuses telles que les trèfles ou les luzernes peuvent servir à la fois de plantes de couverture et d'engrais verts grâce à leur fixation symbiotique d'N atmosphérique. Cependant, leur substitution aux céréales présente un moindre intérêt économique dans les systèmes de grandes cultures en l'absence d'animaux pour les valoriser. L'association relais de couverts de légumineuses dans un blé d'hiver nous a semblé être une option intéressante pour à la fois enrichir le système sol-plante en N, couvrir le sol dès la récolte du blé associé et limiter le risque de compétition avec le blé en décalant au printemps la date de semis des légumineuses sous couvert de blé. Pour évaluer l'efficacité de ces associations, quatre espèces de légumineuses (Medicago lupulina L., M. sativa L., Trifolium pratense L. et T. repens L.) ont été semées au tallage du blé d'hiver sur huit parcelles réparties dans la région Rhône-Alpes. Leurs effets sur la maîtrise des adventices, l'enrichissement, la préservation et la restitution d'N au système sol-plante et les performances des cultures ont été observés, durant une succession blé d'hiver-culture de printemps. Les résidus des couverts ont été enfouis à la fin de l'hiver, 9 à 12 semaines avant le semis d'une culture de printemps. Nos travaux ont montré l'absence d'effet des couverts associés sur le rendement en grains du blé d'hiver. Mais des diminutions du taux protéique des grains sont apparues dans un tiers des situations d'association notamment avec M. lupulina et T. pratense, les espèces les plus développées à la récolte du blé. Notre suivi de la disponibilité des ressources trophiques principales (eau, N, lumière) nous a permis d'identifier une compétition pour l'eau et l'N du sol. Nous avons également noté l'efficacité des couverts de légumineuses dans le contrôle de la densité des adventices dès le stade de floraison du blé et de leur biomasse durant l'interculture. Le meilleur contrôle des adventices a été permis par M. lupulina et T. pratense, à la récolte du blé, et T. pratense et T. repens, à la fin de l'automne, associé aux biomasses aériennes observées les plus importantes. Enfin, nous avons observé une forte proportion d'N issu de la fixation symbiotique dans la biomasse aérienne des légumineuses à la fin de l'automne (80 à 94%), représentant un apport d'N exogène au système sol-plante évalué entre 37 et 77 kg N ha-1. Cet enrichissement en N n'a pas entrainé d'aggravation de la lixiviation d'N durant l'hiver. Les couverts de légumineuses n'ont pas non plus diminué la lixiviation comparativement à l'absence de couvert. Après leur destruction, les résidus des couverts ont restitué une partie de l'N accumulé (+28 à +42 kg ha-1 d'N minéral sur les 90 premiers centimètres de sol par rapport au témoin à l'émergence de la culture de printemps, 12 semaines après leur destruction). Cette restitution a permis un enrichissement en N des pailles et grains de la culture de printemps et une augmentation de 30% du rendement lorsqu'il s'agissait de maïs. Finalement nous concluons sur l'intérêt des couverts de légumineuses associés en relais dans un blé d'hiver pour apporter une réponse positive aux problèmes principaux des rotations de grandes cultures biologiques (adventices, déficits d'N et diminutions des performances des cultures). Nous terminons en proposant des voies d'évolution des associations testées, notamment pour limiter les risques de compétition durant l'association. Nous évoquons également les implications scientifiques et pratiques de ce travail pour de futures études sur ce sujet. / Cereal productivity and quality are subject to two main problems in organic stockless systems: chronic soil nitrogen (N) deficiencies and weed infestation. Legume species as clovers or alfalfas can be used as cover crops and green manures due to their natural ability to fix atmospheric N. Nevertheless, their substitution to cereals in crop rotations is less economically viable without animals to use it. Relay intercropping of legume cover crops (RIL) in winter wheat was expected to simultaneously enrich the soil-plant system in N, cover the soil from the wheat harvest onwards and limit the risk of competition with wheat by delaying the undersowing of legumes in spring. To evaluate the efficiency of RIL, four legume species (Medicago lupulina L., M. sativa L., Trifolium pratense L. and T. repens L.) were undersown at wheat tillering stage, in eight fields organically managed in the Rhône-Alpes region, France. Their effects on weed control, on N enrichment, preservation and restitution in the soil-plant system and on crop performance were observed during the succession of the winter wheat and a spring crop. RIL residues were incorporated in soil in late winter, 9 to 12 weeks before the sowing of spring crops. Our work illustrated the absence of detrimental effect of RIL on wheat grain yield despite the decrease of the grain protein content in one third of the situations. This decrease was mainly observed with M. lupulina and T. pratense as they were the most developed legume species at wheat harvest. Our monitoring of trophic resources (water, N and light) enlightened the competition for soil water and N during the intercropping period. We also showed the efficiency of RIL in the control of weed density from wheat flowering stage onwards and of weed aerial biomass in late autumn. The best weed control was observed with M. lupulina and T. pratense, at wheat harvest, and with T. pratense and T. repens in late autumn, in relation to the highest aerial biomasses observed with these species. Finally, we noted an important proportion of N derived from atmosphere (Ndfa) in legumes' shoots in late autumn (80 to 94%), representing an input of exogenous N in the soil-plant system ranging from 37 to 77 kg Ndfa ha-1. The N enrichment of the system did not increase mineral N lixiviation during winter. However, legume cover crops did not significantly prevent any lixiviation of mineral N relative to the control without cover crop. After their ploughing in, legumes residues returned a part of the accumulated N (+28 to +42 kg ha-1 of mineral N in the first 90 cm of soil compared to the control at the emergence of the spring crop, 12 weeks after ploughing). This restitution of mineral N allowed a significant N enrichment of straw and grains of the spring crop with all previous legumes cover crop species. With maize as spring crop, the grain yield increased by 30%, on average, compared to the control treatment. We finally conclude on the interest of RIL in winter wheat to bring a positive response to the problems of weed control, N deficiency and crop performances in organic crop rotations. We then suggest possible improvements of the RIL system, especially against the competition for trophic resources during the relay intercropping period. We also mention scientific and practical implications of this work for future studies on this subject.

The theoretical part of the thesis focuses on organic food and ecological agriculture problematics. The primary objective is to point out advantages and disadvantages of organic food and therefore, I mention comparison of organic and conventional food in the thesis. The practical part investigates attitudes and levels of knowledge of students of selected lyceums about organic food. The quantitative research (survey) was conducted at three lyceums in Prague. The statistical methods were used to verify the stated assumptions. While processing the survey I have learned that students struggle with the field of healthy nutrition than with the field of ecological agriculture and therefore, a proposal of healthy nutrition and organic food lecture has been chosen as the pedagogical output of the thesis. A tutoring presentation will focus on students of lyceums and its purpose will be to raise awareness about this problematic.

Based on survey results and market analysis to assess the current status and trends on the market with organic products and also bring conclusions and recommendations concerned the strategies for further action in "ORGANIC" domain.

L’agriculture biologique (AB) est souvent présentée comme une alternative prometteuse à l’agriculture conventionnelle, permettant des systèmes alimentaires durables tout en minimisant les impacts environnementaux. La capacité de l’AB à satisfaire la demande alimentaire mondiale reste néanmoins fortement débattue. Plusieurs études ont conclu que l’AB pourrait satisfaire la demande alimentaire globale à condition de réduire simultanément la consommation de produits animaux et les gaspillages. Cependant, ces études n’ont pas pleinement pris en compte les changements d’assolement et de choix d’espèces lorsque les systèmes conventionnels sont convertis en AB. Surtout, ils ont ignoré le rôle clé de la disponibilité en azote (N) dans le maintien des rendements en AB. Dans cette étude, nous avons d’abord réalisé une méta-analyse comparant les rotations de cultures en agriculture biologique et conventionnelle à l’échelle mondiale. Sur la base de ces résultats, nous avons développé une cartographie des espèces cultivées à l’échelle globale sous un scénario de fort développement de l’AB. Nous avons ensuite estimé la production alimentaire grâce au développement de GOANIM (Global Organic Agriculture NItrogen Model), un modèle biophysique et spatialement explicite d’optimisation linéaire simulant le cycle de l’azote (N) et ses effets sur la production alimentaire globale. GOANIM est adapté au cas de l’AB et simule les flux d'azote entre les terres cultivées, les animaux d'élevage et les prairies permanentes, ainsi qu’entre les systèmes agricoles biologiques et conventionnels. Le modèle optimise les populations d’élevage à l’échelle locale afin de maximiser l’approvisionnement en N provenant du fumier, ce qui maximise la production issue des terres cultivées, tout en minimisant la concurrence exercée par les animaux pour les ressources alimentaires. GOANIM a été utilisé pour simuler l’offre alimentaire sous plusieurs scénarios de conversion à l’AB. Ces résultats ont été comparés à différentes estimations de la demande alimentaire mondiale. Nous montrons que la carence en N risque d’être un facteur limitant majeur de la production en AB, entraînant une réduction de -37% de la disponibilité alimentaire à l’échelle globale sous un scénario de conversion à l’AB de 100%. Nous montrons que des taux de conversions inférieurs (jusqu'à 60% des terres agricoles), en coexistence avec l'agriculture conventionnelle, permettent de satisfaire la demande alimentaire mondiale si cette conversion est associée à une évolution conjointe de la demande, telle que la réduction de l'apport énergétique par individu ou du gaspillage alimentaire. Ces travaux contribuent de manière substantielle à mieux comprendre le rôle que l’AB peut jouer dans la transition vers des systèmes alimentaires équitables et durables. Ils indiquent également des voies à suivre pour parvenir à la sécurité alimentaire mondiale. / Organic agriculture is often proposed as a promising approach to achieve sustainable food systems while minimizing environmental impacts. Its capacity to meet the global food demand remains, however, debatable. Some studies have investigated this question and have concluded that organic farming could satisfy the global food demand provided that animal product consumption and food waste are reduced. However, these studies have not fully considered the changes in the type of crops grown that occur when conventional farming systems are converted to organic farming. Most importantly, they also have missed a critical ecological phenomenon by not considering the key role that nitrogen (N) cycling plays in sustaining crop yields in organic farming. In this study, we first carried out a global meta-analysis comparing organic vs conventional crop rotations. Based on these results, we developed global spatial explicit maps of the type of crop grown if organic farming was to drastically expand. We then estimated organic global food production using GOANIM (Global Organic Agriculture NItrogen Model), a spatially explicit, biophysical and linear optimization model simulating N cycling in organically managed croplands and its feedback effects on food production. GOANIM explores N flows between croplands, livestock animals and permanent grasslands, and with conventional farming systems. The model optimizes livestock populations at the local scale in order to maximize N supply from livestock manure – hence maximizing cropland production –, while minimizing the animals’ competition for grain food resources. We used GOANIM to simulate several supply-side scenarios of global conversion to organic farming. We then compared the outcomes of these scenarios with different estimates of the global demand, thus leading to complete exploration of the global production-demand options space. We show N deficiency would be a major limiting factor to organic production in a full organic world, leading to an overall -37% reduction in global food availability. Nevertheless, we also show that lower conversion shares (up to 60%) would be feasible in coexistence with conventional farming when coupled with demand-side solutions, such as reduction of the per capita energy intake or food wastage. This work substantially contributes to advancing our understanding of the role that organic farming may play to reach fair and sustainable food systems, and it indicates future pathways for achieving global food security.

El presente artículo de investigación desea poner en conocimiento al lector, la baja productividad existente en la producción de alimentos orgánicos; este estudio, se enfocará específicamente en la producción de uva. El análisis e información recabada en el sector de la agricultura orgánica, ha permitido descifrar que esta problemática surge a raíz de los tiempos improductivos que se originan en cada fase de la producción de uva orgánica, generando sobrecostos innecesarios, a ello se le suma la inexistencia de procedimientos que deberán seguirse para mantener una producción sin mermas y correctamente estandarizada. El objetivo final del presente estudio fue reducir tiempos improductivos en una MYPE del sector agrícola, identificando y solucionando el problema principal y evitando la aparición de sus causas raíz. El principal problema encontrado fue el tiempo improductivo que se genera en los procesos de Abonado y Cosecha. Método: para dar solución a dicho problema, se diseñó un modelo de estandarización de procesos, empleando la herramienta de mejora continua PDCA. Resultados: como principal resultado del modelo propuesto de estandarización tenemos que la productividad se incrementó en un 25% en relación a la última producción del año 2019, además, entre otros resultados, se obtuvo la reducción en los tiempos improductivos en un 36%, lo que significó para la empresa un ahorro de S/. 5,762.62. Conclusión: El estudio demostró que, con un replanteamiento ordenado de los procesos y la disposición de la empresa a cooperar con la mejora, se pueden lograr resultados positivos, a pesar de que el proyecto no significa una gran inversión. / The present research article wishes to bring to the attention of the reader the low productivity that exists in organic food production; this study will focus specifically on grape production. The analysis and information gathered in the organic agriculture sector has allowed us to decipher that this problem arises due to the unproductive times that originate in each phase of the production of organic grapes, generating unnecessary costs. The final objective of the present study was to reduce unproductive time in an MSE of the agricultural sector, identifying and solving the main problem and avoiding the appearance of its root causes. The main problem found was the unproductive time generated in the Fertilizer and Harvest processes. Method: To solve this problem, a process standardization model was designed, using the PDCA continuous improvement tool. Results: As the main result of the proposed model of standardization we have that productivity increased by 25% in relation to the last production of 2019, in addition, among other results, we obtained the reduction in unproductive time by 36%, which meant a saving of S/. 5,762.62 for the company. Conclusion: The study showed that, with an orderly rethinking of processes and the company's willingness to cooperate with improvement, positive results can be achieved, even though the project does not involve a large investment. / Trabajo de investigación

Fodder maize cultivation under low mountain conditions in Central Europe presents obstacles for organic dairy farmers; low temperatures and high precipitation values in spring delay the juvenile development of maize, which leads to lower and fluctuating yields. Increasing the soil temperature during the critical growth phase of maize in spring is beneficial for maize cultivation. For this reason, 0.15 m high ridge-row cultivation (RCM) of maize was compared to a typical flat surface cultivation method (FCM) with 0.75 m row spacing in three environments (En) in 2017, 2018 and 2020 on-farm at low mountain sites in Germany. In the experiment, with randomised block design and one-factorial arrangement, soil temperature (ST) at 0.05 m soil depth at midday, field emergence (FE) 4, 8, 16 and 20 days after sowing (DAS), dry matter yields (DM) in every En and plant development and N, P, K content in En 2020 were investigated. RCM led to a significantly higher ST 4 DAS in every En, 12 and 20 days in 2018 and 8 and 16 DAS in 2020. RCM did not accelerate maize FE but positively impacted plant development and starch content. RCM generated a higher dry matter (DM) yield of whole maize plants and corn cobs, and a higher protein yield than FCM. RCM slightly increased the plant-available P and Mg content from 0 to 0.3 m and influenced significantly the mineral N content from 0 to 0.3 m at the beginning of grain development. RCM, a simple cultivation technique, demonstrated benefits for maize cultivation, particularly for climatically marginal locations in Germany.

Dagens matproduktion har fått ökad uppmärksamhet kring hur den kan anpassas för att försörja en växande befolkning, utan att negativt påverka klimatet. Att ställa om till ekologiskt är en presenterad lösning och politiker på nationell och europeisk nivå har satt tydliga mål och åtgärder gällande ekologiskt jordbruk, dels om andelen ekologiskt jordbruk, dels om hur det ska uppnås. En åtgärd EU presenterat är ekodistrikt, som är ett geografiskt område där flera aktörer i livsmedelskedjan hållbart förvaltar de lokala resurserna genom ekologiska metoder och principer. Det har lett till ökad uppmärksamhet för redan befintliga ekodistrikt samt till etableringar av nya ekodistrikt, däribland det första svenska ekodistriktet i landskapet Södermanland, “Ekodistrikt Sörmland”. Rapportens syfte är att ge ökad förståelse för vad som definierar samt möjliggör ekodistrikt samt studera förutsättningar som finns för etableringen av Ekodistrikt Sörmland. I rapporten genomfördes en litteraturstudie om ekodistrikt med bland annat en tematisk analys där relevanta faktorer för etablering av ekodistrikt identifierades: “myndigheter och organisationer”, “bottom-up tillvägagångssätt”, “kultur och turism”, samt “jordbruksmöjligheter”. Även en fallstudie om Ekodistrikt Sörmland utfördes som inkluderade en litteraturstudie med en kompletterande intervju. Resultatet visade att ekodistrikt bygger kring dimensionerna ekologisk, social och ekonomisk hållbarhet och i Europeiska kommissionens definition av ekodistrikt framgår det att lokala resurser ska förvaltas hållbart i ett ekodistrikt. Mat i ekodistrikt ska produceras från ekologiska gårdar som minskar påverkan på miljön, jordbruket ska bli lönsamt genom nya marknadsmöjligheter och det sociala kapitalet stärks genom att ekodistrikt främja ökad sysselsättning på landsbygden. Möjligheten att etablera ekodistrikt skiljer sig mellan områden och olika förutsättningar kräver olika tillvägagångssätt. Tillgängliga litteraturen hänvisade till första etablerade ekodistriktet, Biodistretto Cilento, som anses som ‘best practice’ för ekodistrikt idag. Resultatet tyder på att det finns indikatorer som i generella fall tyder på goda förutsättningar att etablera ekodistrikt, men att dessa kan variera utefter lokala förutsättningar. Bilden som erhölls kring frågan vad möjliggör ekodistrikt är att ekodistrikt förlitar sig på kommunikation nerifrån och uppåt - från bönder till beslutsfattare, lokala samarbeten aktörer emellan mot annars icke identifierade gemensamma mål, samt innovativa lösningar och system utefter lokala förutsättningar och ekologiska principer. Ekodistrikt Sörmland planeras att omfatta landskapet Södermanland, bestående av Södermanlands län och södra delarna av Stockholms län. Vid rapportens tidpunkt var inte samtliga kontaktade. Ekodistriktet är del av och delfinansieras av ett treårigt EU-projekt. Initiativtagarna för ekodistriktet vill åstadkomma ett hållbart matsystem som baseras på Södermanlands lokala resurser och att öka allmänhetens kunskap om ekodistrikt. I nuläget är 21 procent av Södermanlands totala jordbruksareal ekologiskt och allmänheten har ett tidigare intresse för ekologiskt och lokalproducerat mat, vilket tyder på områdets potential för utveckling av ett ekodistrikt. Däremot det tidiga stadiet i etableringsprocessen, är det svårt att avgöra i denna rapport huruvida verksamheten kommer att fungera. Resultatet diskuteras därefter utefter de identifierade faktorer i relation till Ekodistrikt Sörmland, samt i vilken mån de kan appliceras och generaliseras på kommande ekodistrikt. / The current state of food production faces challenges, as to how it can be adapted to the increase in the global population, without the least impact on the earth's climate. The given course of action is an organic transition in order to achieve sustainable farming. One course of action, presented by the EU, are biodistricts (Swedish: ekodistrikt), a geographical area wherein stakeholders in the value chain sustainably co-manage the local resources through organic farming principles. EU’s recognition has enabled an increased focus on already established biodistricts, as well as the establishment of new ones, including the first Swedish biodistrict in the region of Södermanland, called "Ekodistrikt Sörmland". The purpose of this report is to provide an increased understanding of what defines and enables biodistricts, as well as to study the conditions for establishing a biodistrict in the region of Södermanland. This was achieved through a literature review on biodistricts, wherein thematic analysis was applied and revealed relevant factors for establishing ecodistricts: “authority and organization”, the “bottom-up approach”, “culture and tourism” and “agricultural capacity”. A case study on Ekodistrikt Sörmland was also performed, which included a complementary interview. The report findings showed that biodistricts are founded on the three dimensions of ecological, social and economic sustainability, through decreased environmental impact, increased market opportunities, and an increase in the local social capital through increased employment opportunities in the countryside. In identifying enabling factors for establishing a biodistrict, findings revealed that local conditions for establishment can vary widely, but that different conditions call for different solutions. Biodistricts rely on the bottom-up approach, wherein farmers communicate their needs to authority, and local cooperationco-management is encouraged through discussion, towards otherwise unidentified common goals, via innovative solutions and organic farming principles. Ekodistrikt Sörmland will include the region of Södermanland: Södermanland county and the south part of Stockholm county, as part of a 3 year EU financed project, wherein the founders aspire to create a sustainable food-system based on local resources and educational principles. As 21 % of the agricultural area in Södermanland is organic farmland, alongside a popular culture of environmental awareness and organic food, the area seems promising for the future development of the biodistrict. It is however too early to speculate on the inner workings of the district, as it is in its early planning phase. Conclusively, the identified enabling factors are discussed in relation to Ekodistrikt Södermanland.
