ABSTRACT The four gene products of the accessory gene regulator (agr) P2 operon of Staphylococcus aureus assemble a quorum-sensing system: AgrA and AgrC resemble a two-component signal transduction system, and AgrB and AgrD are required to produce an autoinducing peptide. Upon activation, this quorum-sensing system positively regulates the transcription of the P2 operon as well as the P3 operon, whose transcript, RNAIII, regulates the expression of virulence genes. Four groups of S. aureus have been identified based on the agr sequences and the group-specific interaction between the autoinducing peptide and AgrC. AgrB is a transmembrane protein involved in the processing of AgrD propeptide, and its interaction with AgrD is also group specific. In this study, a series of chimeric AgrBs were constructed by swapping between group I and group II AgrBs, and these mutants were used to analyze the group-specific segment(s) in AgrB that was responsible for AgrD processing. Our results revealed that the first transmembrane α-helix and the extracellular loop 1 of group I AgrB were decisive in the specific processing of group I AgrD. In contrast, two hydrophilic segments of group II AgrB played a crucial role in the group-specific processing of group II AgrD. We also found that several chimeric AgrBs were capable of processing AgrD from both groups, suggesting that all AgrB homologues may utilize the same or a similar mechanism in the processing of AgrDs.

Development and climate change are crucial global concerns with significant contrasts between developed and developing nations. Contrary to several developing countries, Rwanda opted for a green growth policy pathway while struggling with its economic emergence through the alternative green sectors, including agriculture. No research has yet been conducted on the choice’s performance on emission sequestration or the country’s income, allowing the formulation of strategies accordingly. The environmental Kuznets curve (EKC), mostly adopted by developed countries, is applied for the Rwandese scenario to verify its adoption in developing countries. The within and between effects of the agricultural sector (AGRc) and gross domestic products (GDPc) on CO2 emission (CO2) are examined with an Autoregressive Distributed Lag (ARDL) cointegration and coupling methods in January 2008−December 2018 period. Results confirm the short-run and long-run cointegration relationships of variables, where CO2-GDPc and CO2-AGRc are relatively decoupling and absolute decoupling, respectively. The EKC adoption to CO2-GDPc relationship, and the significant negative causality from GDPc and AGRc to CO2, are confirmed. The performance resulted from the country’s environment conservation policies, and Rwanda is a learning example as a developing country. However, the green economy through the agro-economy is at a low level and should be reinforced.

ABSTRACT In this study, we investigated the agrBDCA operon in the pathogenic bacterium Listeria monocytogenes EGD-e. In-frame deletion of agrA and agrD resulted in an altered adherence and biofilm formation on abiotic surfaces, suggesting the involvement of the agr system of L. monocytogenes during the early stages of biofilm formation. Real-time PCR experiments indicated that the transcript levels of agrBDCA depended on the stage of biofilm development, since the levels were lower after the initial attachment period than during biofilm growth, whereas transcription during planktonic growth was not growth phase dependent. The mRNA quantification data also suggested that the agr system was autoregulated and pointed to a differential expression of the agr genes during sessile and planktonic growth. Although the reverse transcription-PCR experiments revealed that the four genes were transcribed as a single messenger, chemical half-life and 5′ RACE (rapid amplification of cDNA ends) experiments indicated that the full size transcript underwent cleavage followed by degradation of the agrC and agrA transcripts, which suggests a complex regulation of agr transcription.

Staphylococcus aureus is a major human bacterial pathogen that carries a large number of virulence factors. Many virulence factors of S. aureus are regulated by the accessory gene regulator (agr) quorum-sensing system. Phenol-soluble modulins (PSMs) are one of the agr-mediated virulence determinants known to play a significant role in S. aureus pathogenesis. In the present study, the efficacy of thymol to inhibit PSM production including δ-toxin in S. aureus was explored. We employed liquid chromatography–mass spectrometry (LC–MS) to quantify the PSMsα1–PSMα4, PSMβ1 and PSMβ2, and δ-toxin production from culture supernatants. We found that thymol at 0.5 MIC (128 μg/mL) significantly reduced the PSMα and δ-toxin production in S. aureus WKZ-1, WKZ-2, LAC USA300, and ATCC29213. Downregulation in transcription by quantitative real-time (qRT) PCR analysis of response regulator agrA and receptor histidine kinase agrC upon 0.5 MIC thymol treatment affirmed the results of LC–MS quantification of PSMs. In silico molecular docking analysis demonstrated the binding affinity of thymol with receptors AgrA and AgrC. Transmission electron microscopy images revealed no ultrastructural alterations (cell wall and membrane) in thymol-treated WKZ-1 and WKZ-2 S. aureus strains. Here, we demonstrated that thymol reduces various PSM production in S. aureus clinical isolates and reference strains with mass spectrometry.

ABSTRACT Staphylococcus aureus KSI9051 has a complex mutation that was associated with the aberrant expression of cell surface and extracellular proteins (M. S. Smeltzer, M. E. Hart, and J. J. Iandolo, J. Bacteriol. 61:919–925, 1993). This mutation was named xpr, although no specific gene was identified. Here this mutation is referred to as Δ1058::Tn551. In this study, we show that in strain KSI9051, the Δ1058::Tn551 mutation occurred coincidentally with a frameshift in agrC that is expected to truncate the sensor component of the known staphylococcal global regulatory locus agr. Remarkably, pleiotropic mutations affecting cell surface and extracellular proteins are generated at frequencies approaching 50% upon the transduction of erythromycin resistance (Emr) encoded by Δ1058::Tn551 from S. aureus KSI905 back to its parental strain, S6C. Three independent isolates created in the manner of KSI9051 contained mutations within agrC. Each isolate had different mutations, suggesting that the transduction of Emr encoded by Δ1058::Tn551 affects the stability ofagrC in S6C. In similar experiments with strains from anS. aureus 8325 genetic background, a mutant AgrC phenotype could not be isolated, implying that strain S6 has aberrant genetic behavior. A comparison of the nucleotide sequences of AgrC from several strains revealed seven errors in the GenBank entry for agr(X52543 ); these data were confirmed with plasmid pRN6650, the original wild-type clone of agr.

ABSTRACT The virulence of Staphylococcus aureus is controlled by the accessory gene regulator (agr) system, including an extracellular inducer encoded by agrD. Variableagr PCR restriction fragment length polymorphism (RFLP) patterns of unique S. aureus strains (n = 192) were determined for a region comprising agrD and parts of the neighboring agrC and agrB genes. Twelve unique RFLP patterns were identified among S. aureusstrains in general; these patterns were further specified by sequencing. All sequences could be catalogued in the three currentagr groups. A major proportion of the S. aureusstrains belong to agr group 1, whereas only 6% of the methicillin-susceptible S. aureus strains and 5% of the methicillin-resistant S. aureus strains belong toagr groups 2 and 3, respectively. The homology between groups varied from 75 to 80%, and within groups it varied from 96 to 100%. Different levels of sequence variability were observed in the different agr genes. agr-related bacterial interference among colonizing S. aureus strains in the noses of persistent and intermittent human carriers was studied.S. aureus strains belonging to different agr groups were encountered in the same individual. This may suggest that the activity of the agrD gene product does not define colonization dynamics, which is further substantiated by the rarity ofagr group 2 and 3 strains.

ABSTRACT The accessory gene regulator (agr) locus, a candidate system for the regulation of the production of virulence factors in Staphylococcus intermedius, has been characterized. Using PCR-based genome walking, we have obtained the first complete sequence (3,436 bp) of the accessory gene regulator (agr) gene in this organism. Sequence analysis of the agr gene has identified five open reading frames (ORFs), agrB, agrD, agrC, agrA, and hld. The translated ORF contained amino acid motifs characteristic of the response regulator and histidine protein kinase signal transducer of the classic two-component regulatory system. Sequencing of the agrD PCR products amplified from DNA from 20 different isolates has facilitated detection of genetic variation in the putative autoinducing peptide (AIP) within the agr gene of S. intermedius, revealing the presence of at least three agr specificity groups within this species. Classification of the agr gene from S. intermedius was supported by phylogenetic analysis. Real-time PCR also revealed that the effector molecule of the agr system, RNAIII, was regulated in an autocrine manner in S. intermedius and demonstrated positive correlation with the temporal gene expression patterns of luk and entC. Transcription of RNAIII was also dependent on self secreted cues. Cyclic self and nonself peptides were synthesized on the basis of the novel AIPs produced by S. intermedius, which lack the cysteine necessary to form the thiolactone ring in analogous peptides from Staphylococcus aureus and Staphylococcus epidermidis. Experiments with these synthetic cyclic peptides indicated that self peptides led to up-regulation of RNAIII—findings in support of the assumption that activation of the agr gene is initiated by growth- and species-specific factors generated during bacterial growth.

Staphylococcus aureus is an important human pathogen. The emergence of multiple antibiotic resistant bacteria and lack of new antibiotics has highlighted the need for better understanding of staphylococcal physiology, molecular biology and virulence. In S. aureus the agr quorum sensing (QS) system is a global regulator of virulence. In the agr system an autoinducing peptide (AIP) activates the histidine protein kinase (HPK), AgrC, leading to a switch from the production of colonization factors to exotoxins. The S. aureus agr system has diverged such that there are four different agr groups, each with a distinct AIP capable of activating its cognate AgrC but inhibiting the AgrC of the other groups. To investigate the molecular basis for the recognition of AIPs by AgrC, transmembrane topology modelling together with site-specific mutagenesis were used. The transmembrane topology of AgrC was predicted to consist of six transmembrane helices (TMHs) and three extracellular loops with both the N- and C-terminals on the cytoplasmic side. Since AIP-1 and AIP-4 differ by a single amino acid residue, the S. aureus AgrC1 and AgrC4 proteins were compared to identify extracellular amino acids likely to be involved in AIP recognition. Site-specific mutagenesis was used to exchange the key AgrC1 and AgrC4 amino acid residues in extracellular loops 1 and 2. The response of these AgrC mutants was evaluated using a novel bioluminescent AIP reporter. The data obtained showed that differential recognition of AIP-1 and AIP-4 depend primarily on three amino acid residues in loop 2, but that loop 1 plays an essential for activation but not for inhibition of AgrC. The data obtained also revealed that a single mutation in the AgrC1 loop2 results in conversion of (ala5)AIP-1 from a potent antagonist to an activator, essentially forcing the evolution of a fifth agr group. Attempts to identify AgrC in the cytoplasmic membrane using Western blotting failed, but data obtained using an N-terminal gfp tag showed that AgrC is evenly distributed through out the membrane. Since the processing of AgrD by AgrB to generate an AIP requires at least 3 steps - two endopeptidase steps and the formation of a thiolactone bond to form the macrocycle, it is likely that other proteins are involved in the processing of AgrD and export of the AIP. To identify potential AgrB partners, yeast two hybrid assay was employed which revealed a potential role for the putative ABC transporter Rlp in the processing and/or secretion of AIP. In summary, the data presented define the key amino acid residues involved in AIP/AgrC interactions and imply a role for proteins such as Rlp in AIP synthesis and export.

The accessory gene regulator (agr) quorum-sensing system is one of the major regulators of virulence factor production in the pathogen Staphylococcus aureus. Activation of the system depends on the production and sensing of a cyclic peptide signal called the autoinducing peptide (AIP). The biosynthesis of AIP depends on the coordinated action of the AgrB integral membrane endopeptidase and SpsB signal peptidase to process the peptide precursor AgrD into the final signal structure. The primary goal of this dissertation was to gain further insight on the role of AgrD and AgrB in the AIP biosynthesis mechanism. Studies in Chapter II were undertaken to better understand the role of AgrD domains in AgrB-mediated processing. A series of truncation and site-directed mutagenesis studies identified key residues in the AgrD C-terminus that were essential for AgrB processing and AIP production. In parallel, genetic manipulation of the N-terminal leader and AIP-encoding sequence revealed a role for these segments in AIP processing. For the first time, a complex of AgrD covalently linked to AgrB was identified, supporting proposals that this intermediate is an important precursor to AIP production. In Chapter III structure-function studies were performed on AgrB to gain further insight into the AIP biosynthetic mechanism. Initially, the agrBD genes were subjected to random mutagenesis and screened for deficiencies in AIP production. Single-site mutations at 20 different residues within AgrB and another 14 in AgrD were isolated. Interestingly, new mutations in the AgrD N-terminal leader were identified that affect AIP biosynthesis at different steps. In AgrB, most of the mutations blocked peptidase activity, but charge alterations to the K129-K131 region were defective in a later pathway step, separating the peptidase function from AIP ring formation and transport. To localize the AgrB mutations, we reevaluated the membrane topology using the substituted cysteine accessibility method. Our new model predicts four transmembrane helices and a reentrant loop, with both termini located outside of the cell. Finally, co-immunoprecipitation studies indicate that AgrB forms oligomeric structures within the membrane. Taken together, these findings provide a better understanding of the functional role of specific AgrD and AgrB regions in AIP biosynthesis.

I sistemi pastorali possono fornire una vasta gamma di servizi ecosistemici che vengono definiti dal Millennium Ecosystem Assessment come “i benefici che le persone ottengono dagli ecosistemi” e vengono classificati in quattro gruppi: i) supporto (necessari per la produzione di tutti gli altri servizi ecosistemici; es. produzione primaria), ii) approvvigionamento (prodotti forniti dagli ecosistemi; es. cibo, acqua), iii) regolazione (benefici ottenuti dalla regolazione dei processi ecosistemici; es. regolazione del clima) e iv) valori culturali (benefici non materiali che la popolazione ottiene dagli ecosistemi; es. esperienze estetiche). L’obiettivo principale della tesi è stato quello di utilizzare le analisi di alcuni dei più importanti servizi ecosistemici forniti dai sistemi agro-pastorali estensivi della regione Marche (Italia centrale), a supporto dei processi di co-progettazione di misure agro-climatico ambientali. Nel capitolo iniziale, attraverso un lavoro di review della letteratura scientifica, la tesi esamina le tendenze e gli approcci utilizzati nell’analisi di alcuni servizi ecosistemici forniti dai sistemi pastorali alla luce dei principi del Millennium Ecosystem Assessment. Successivamente, la tesi si concentra principalmente sull’analisi delle emissioni di alcuni gas ad effetto serra generati da diversi sistemi colturali e diverse gestioni: (i) respirazione del suolo di una prateria montana a dominanza di Bromus erectus sottoposta a diverse intensità di utilizzazione; (ii) emissioni di N2O in un sistema medica-frumento, con e senza l’applicazione di biochar, in un’area collinare. Nell’ultimo capitolo, la tesi analizza i processi di progettazione di misure agro-ambientali per la gestione di problematiche ambientali a scala territoriale in numerosi casi di studio. L’analisi della letteratura ha rivelato una generale confusione da parte dei portatori d’interesse relativamente al concetto di servizio ecosistemico. La biodiversità viene considerata un servizio ecosistemico di per sé e la visione antropocentrica dei servizi ecosistemici non è accettata o compresa. Dalla review emerge inoltre lo scarso utilizzo di un approccio multi-settoriale nell’analisi dei servizi ecosistemici, nonché quello di un’integrazione delle diverse conoscenze. In aggiunta, i servizi ecosistemici culturali risultano scarsamente studiati, nonostante siano considerati di grande importanza per i portatori d’interesse sia locali che generali e che, insieme ad altri importanti servizi ecosistemici, potrebbero favorire l’adozione di politiche e misure agro-ambientali. Dall’analisi della prateria a dominanza di Bromus erectus, non emerge nel breve periodo un impatto significativo dell’intensità di utilizzazione sulla respirazione del suolo né sulla produzione primaria. Nel sistema medica-frumento, l’analisi delle emissioni di N2O suggerisce che: i) la lavorazione posticipata in autunno può mitigare la perdita di azoto sottoforma di N2O; ii) gli effetti dell’applicazione del biochar dovrebbero essere analizzati nel lungo periodo per verificare i possibili effetti dell’invecchiamento del biochar, anche sulla produttività della coltura. I risultati ottenuti da questa ricerca potrebbero contribuire alla condivisione di conoscenze e alla formazione di una conoscenza ibrida che, insieme al cambio di ruolo dei portatori d’interesse del sistema, sono risultati elementi chiave del processo di co-progettazione di misure agro-climatico ambientali sito specifiche, condivise e a scala territoriale.Grazing systems can provide a wide array of ecosystem services, defined by the Millennium Ecosystem Assessment as “the benefits that people obtain from ecosystems” and classified in four main groups: i) supporting (necessary for the production of all other ecosystem services; e.g. primary production), ii) provisioning (products obtained from ecosystems; e.g. food, fresh water), iii) regulating (benefits obtained from the regulation of ecosystem processes; e.g. climate regulation) and iv) cultural (non-material benefits people obtain from ecosystems; e.g. aesthetic experiences). The thesis aims to investigate some relevant ecosystem services provided by extensive agro-pastoral systems in the territory of the Marche region (central Italy) to support the co-design process of agrienvironmental climate measures. The thesis originates from a review paper that analyses the trends and approaches used in the analysis of relevant ecosystem services provided by grazing system, according to the framework principles of the Millennium Ecosystem Assessment. In a following step, the research focuses on the analysis of the greenhouse gases emissions under different cropping systems and management options: soil respiration from a Bromus erectus-dominated grassland under different mowing intensities in the uplands and N2O emissions in a alfalfa-wheat system with biochar application in the lowlands. A final chapter analyses the design process of agri-environmental measures at landscape scale implemented in several case studies. The literature review revealed a misunderstanding concerning the concept of ecosystem services among stakeholders. The biodiversity was considered an ecosystem services per se and the anthropocentric vision of the ecosystem services was not accepted or understood, moreover a lack of a multi-sectoral approach in the analysis of ecosystem services and the integration of different knowledge emerged. Furthermore, cultural ecosystem services were poorly studied despite being considered the most relevant for local and general stakeholders and with some other relevant services, could foster agri-environmental schemes. From the analysis of the soil respiration from a Bromus erectus-dominated grassland emerged that more intensive use did not significantly impact soil respiration and primary production on the short term. The analysis of the N2O emissions in the alfalfa-wheat system suggests that: i) postponed tillage in autumn may mitigate nitrogen losses as N2O after alfalfa termination; ii) the effects of biochar application on N2O emissions and crop productivity should be analysed in a long term perspective to verify the ‘biochar aging’. The results obtained from the research could feed the hybrid knowledge, that with shift of the stakeholder role in the system are key elements for the co-design process of site specific, shared and landscape agrienvironmental measures.

Doutoramento em Arquitectura Paisagista - Instituto Superior de AgronomiaThe present dissertation is focused on the study of contemporary Food Planning, an emerging area of interdisciplinary research, with greater development in Europe, U.S.A. and Canada. The limits to the approaches for the conservation of agricultural land, current at the end of the century XX, have been identified in several countries, including France, where peri-urban agricultural policies, have been implemented since the 70s. In the 90s, the experiences of collective action of local initiative by elected officials, urban residents and managers of rural areas, have helped to limit urbanisation and to the development of agricultural projects – agrourban programs. These were designed to protect the economic viability of agriculture through development programs, which in the metropolitan context take into account the specificity of the peri-urban agriculture and its potential for the development of Short Food Supply Chains (SFSCs). In this context, knowing the productive potential of a region on the basis of existing food needs is of paramount importance to policies aimed at creating Local Food Systems or Territorial Food Systems. Considering the role of Landscape Architecture in ecologically based Landscape Planning, the main objective of this thesis is to evaluate the proposal for food system relocalisation, considering production side of the food system, in the case study area – Ribatejo e Oeste. The results of the Landscape Foodshed Plans to be presented will demonstrate the potential for the relocalisation of the food system, while ensuring the sustainable use of the regional ecological basis of food security. In the context of the current debate on diets sustainability in the Global North countries, three diets will be tested with variable degrees of affluence, to take in account differences in land use

Desde el inicio, el ser humano a creado asentamientos en base a la relación que establece
con el medio natural, agua, energía y suelo para poder abastecerse de alimento y
sobrevivir. Hoy en día las ciudades se han planteado en base a crear asentamientos en
grandes magnitudes, donde el ser humano pierde la conexión con el medio natural y
principalmente con sus necesidades básicas, convirtiendo a la ciudad en un organismo
altamente dependiente de combustibles fósiles para abastecer a sus habitantes y trayendo
consigo problemáticas dentro de lo que hoy entendemos como calentamiento global.
En este contexto nace la Comunidad Agro-Sustentable experimental en San José
de Maipo, que plantea una forma de expansión urbana, considerando la producción
de alimento como una oportunidad en beneficio directo de la población, dentro de las
estrategias de desarrollo a nivel metropolitano.
El proyecto propone un modelo de comunidad agrícola contemporánea como una
forma de generar asentamientos sustentables. Se Aplicará la agricultura urbana como
herramienta de organización comunitaria. Y se desarrollará una propuesta habitacional en
San Jose de Maipo, que integra la autoproducción de alimentos generando una expansión
y abastecimiento sustentable de la Región Metropolitana.

Previous issue date: 2009-08-25This current study proposal is to analyze the manifestations of the agrarian question as they project themselves in the fight for the work land in the state of Rio de Janeiro at the XXI century. The study is analytically based on the trajectories of the families of agricultural workers from the encampment Terra Prometida. Currently situated in the region called Baixada Fluminense, the encampment holds seventy-four families distributed in its two headquarters: The first one in the district of Tingu?, Nova Igua?u city and the second in the city of Duque de Caxias. That?s about the rescue of the agrarian question in the state of Rio de Janeiro, looked by the trajectory of these families. The state of Rio de Janeiro, although considered predominantly urban, possesses considerable extensions of cultivating lands, many of them idle. It also possesses an increasing number of agricultural workers who, without access to the work in the land, come increasing the mass of urban workers without any qualification, what generates some similar social problems to the ones of other Brazilian states. The observation of the agrarian question redimensioning in the current times generated some questionings that had guided the field research. How can the agrarian question that some authors more affirm not to exist in the current times, still to be reason of as many disputes and fights? Disputes these that happen also in the public space and in the private one, with the occurrence of violence, threats and murders. Could we be coexisting today with a new agrarian question or only the modernized version of a secular question? Is it possible that the agrarian question have been only updated and not disappeared ? For the agricultural workers of century XXI, what or who represents the large state in the present time? Under which forms or aspect materialize their conscience about the work land in the state of Rio de Janeiro of the recent years?
A presente disserta??o se prop?e analisar as manifesta??es da quest?o agr?ria, conforme se projetam na luta pela terra de trabalho no Estado do Rio de Janeiro do s?culo XXI. O estudo tem como base anal?tica as trajet?rias das fam?lias de trabalhadores rurais do Acampamento Terra Prometida. Atualmente situado na regi?o da Baixada Fluminense, o acampamento comporta setenta e quatro fam?lias distribu?das em suas duas sedes: A primeira no distrito de Tingu?, em Nova Igua?u e a segunda, no munic?pio de Duque de Caxias. Trata-se de resgate da quest?o agr?ria no Estado do Rio de Janeiro a partir da trajet?ria destas fam?lias. O Estado do Rio de Janeiro, apesar de considerado predominantemente urbano, possui consider?veis extens?es de terras cultiv?veis, muitas delas ociosas. Possui tamb?m um n?mero crescente de trabalhadores rurais que, sem acesso ao trabalho na terra, v?m se somando ? massa de trabalhadores urbanos sem qualquer qualifica??o, o que gera alguns problemas sociais semelhantes aos de outros estados brasileiros. Desde a d?cada de 1950, o estado ? palco de intensos conflitos pela posse da terra, entretanto, a partir do final do s?culo passado ? poss?vel perceber um redimensionamento destes conflitos, que deixaram de se travar prioritariamente nos espa?os rurais e adquiriram novas caracter?sticas. Os enfrentamentos, assim como as manifesta??es vis?veis da quest?o agr?ria, t?m agora no espa?o urbano um novo palco de conflitos. As observa??es deste redimensionamento da quest?o agr?ria nos tempos atuais geraram alguns questionamentos que nortearam a pesquisa de campo. Como a quest?o agr?ria que alguns autores afirmam n?o mais existir pode, atualmente, ainda ser motivo de tantas disputas e lutas? Disputas estas que se d?o tanto no espa?o p?blico, quanto no privado, com a ocorr?ncia de viol?ncia, amea?as e assassinatos. Estar?amos convivendo hoje com uma nova quest?o agr?ria ou apenas com a vers?o modernizada de uma quest?o secular? ? poss?vel que a quest?o agr?ria tenha apenas se atualizado e n?o desaparecido ? Para os trabalhadores rurais do s?culo XXI, o que ou quem representa o latif?ndio na atualidade? Sob que forma ou aspecto materializa-se a consci?ncia destes trabalhadores sobre a terra de trabalho no estado do Rio de Janeiro dos anos recentes?

In the management of agri-food companies in the Slovak Republic, significant changes have taken place in the last 4 decades, which were caused by social and economic changes in our society. After 1989, it was the transformation of agriculture into a market economy, gradually added to the pre-accession requirements for further changes in the agricultural sector. Accession to the EU meant great challenges, opportunities and risks for Slovak agriculture. However, the decline in agricultural production has not stopped, which is especially true of livestock production. Other obstacles had to be faced by farmers and food producers during the global economic and financial crisis from 2008 to 2010, and currently, in addition to environmental issues, the problems associated with the COVID 19 pandemic and food sufficiency and security are coming to the fore. In addition to addressing all external factors that affect the agri-food complex, managers must address agro-innovation issues and the penetration of new management models and approaches related to providing quality food to final consumers. The purpose of this paper is to point out key socio-economic determinants affecting production and consumption in the agri-food industry.

Recent technological developments and social media have opened up a multitude of opportunities for farmers and agricultural companies to communicate with their customers and marketers. Especially in the EU agri-food sector, smart use of knowledge, research and innovation is the main source of productivity growth. A new digital innovation hub in Precision Agriculture can drive the digital transformation of Europe's agro-food sector, boosting innovation and growth. Moreover, this hub could also play an important role in the exploitation of opinion leadership in agricultural technology and productivity.

The pandemic caused by Covid-19 has been causing a great impact on the world economy since 2020. This study analyses the impact of the pandemic on innovative agri-food companies from different branches of agro-industrial activity located in Extremadura (Spain) to determine which activities have been most affected and whether there are differences between the actions and changes carried out depending on the nature of the product, process or services. The information was obtained using an online questionnaire in which the research questions were proposed (what consequences, actions or changes has the pandemic had on the development of your activities?). Data were analysed descriptively, studying statistically the existence of independence or not between the effects and the actions carried out depending on agri-food industry branches of activity. The main results have shown that in general, all the agro-industrial branches have incorporated changes in their products and services, mainly by providing new and better customer benefits and improving product formats and forms of payment to suppliers

Improved oilseed processing has tremendous potential to improve nutrition, food security, and incomes in sub-Saharan Africa (SSA); however, processors face limitations that hinder their growth. For example, only 56% of soybeans produced in SSA are processed. The Soybean Innovation Lab survey highlighted constraints to agro-processors' operations such as access to raw materials, cash flow, cost of entry and operation, and lack of equipment. But while agri-food processing in SSA is still lagging, Reardon (2015) observed an incipient €œquiet revolution€ in such midstream activities. Today, agro-processors in SSA demonstrate great potential to support economic growth€”from large, international companies, to medium/small enterprises supplying districts and towns, to micro enterprises serving communities. These enterprises also provide income-earning opportunities for women, youth, and vulnerable populations, directly impacting their food security and nutrition. To spur growth, the U.S. Agency for International Development (USAID) and other donors have invested in improving agro-processing in SSA. In Southern Africa, the American Oil Chemists' Society (AOCS), Soybean Innovation Lab, and USAID-funded Farmer-to-Farmer Program implemented by Cultivating New Frontiers in Agriculture (CNFA) are conducting a pilot to connect AOCS volunteers with processors. This presentation reviews the experiences with the partnership and describes how AOCS members can support African agro-processors.

The European integration process has fostered the continuous advancement of economic relations with the EU, necessitating the modernization of domestic legislation through alignment with EU regulations, particularly in the realm of competition within the agro-food sector. The liberalization of competition is a positive catalyst for product diversification, consumer welfare, economic growth, and overall quality of life. The paper aims to assess the level of harmonization between national regulations governing the agrifood market and European regulations. The research entails the analysis of local legislation in the food sector, relevant scholarly works, and reports from the Competition Office. The findings indicate that the food industry and retail food trade are economic activities that require the elimination of anti-competitive barriers and the promotion of free competition. Furthermore, the provision of state aid to public companies must adhere to competition rules and avoid detrimental effects on the functioning of the market's supply and demand mechanism. In addition, the study aims to provide valuable insights into the challenges and opportunities associated with the harmonization process. By examining the effectiveness of existing regulatory frameworks and identifying areas for improvement, this research contributes to the ongoing discussions on promoting fair competition and enhancing market efficiency in the agri-food sector. The findings of this study will inform policymakers, industry stakeholders, and researchers, enabling them to make informed decisions and develop strategies that foster a competitive and sustainable agri-food market in line with European standards. It is important to note that this research represents a preliminary analysis of competition in the agro-food chain, with further exploration planned as part of the doctoral training program.

Responding to a sustainable production is an imperative that is gaining more and more relevance in the definition of specific programs and strategies at national and international level. This urgency leads towards zero waste and circular models and processes that minimize the extraction of resources from the biosphere and do not create waste; instead, when the waste of natural or anthropogenic transformations cannot be avoided, their valorization as resources must be carried out. The development of integrated supply chains, knowledge transfer between different disciplines and the dialogue between research and industry becomes fundamental for the achievement of these objectives. Existing studies in the literature regarding the agri-food production chain in Italy show that the sector, whose environmental impacts are by no means marginal, is fragmented in many small production companies; an interesting and critical aspect at the same time since the generation of waste is not accompanied by an appropriate dissemination of data at a quantitative-qualitative level and there is no clear regulatory framework available on alternative management and valorisation methods. Design, given its natural inclination to transversality, allows to trace scenarios in which to configure, through interdisciplinary approaches, the sustainability models that are intended to be covered in this contribution. Moreover, its methods and tools allow to develop a critical thinking starting from the very early designing phase. The paper addresses the valorisation of agro-industrial waste in a circular and systemic perspective through the presentation of a review of case studies from the textile supply chain, which is one of the most relevant for Italian industry.Due to its disastrous environmental impact, the global textile industry is today the subject of extensive research aimed at the development of innovative materials and processes in order to overcome the traditional linearity of the textile supply chain. The negative impacts of the textile industry are distributed along the entire value chain and are mainly attributable to greenhouse gas emissions -for which the textile industry represents the fifth manufacturing sector- consumption and pollution of water resources and the production of textile waste. In particular, the production of synthetic fibers, which is estimated to be almost two thirds of the global fiber production, is associated with a high use of non-renewable resources and emissions, which derives from the extraction of fossil fuels. In this sense, the valorisation of agro-industrial waste as secondary raw materials and new sustainable inputs for the textile supply chain, represents an opportunity not yet fully explored, in particular as regards the development of a new generation of fibers, yarns and eco-compatible fabrics alternative to the materials currently in use. Bio-based wastes and by-products from agri-food industry could as well present enormous potential for valorisation in the textile finish due to their intrinsic properties (antimicrobial, prebiotic, antioxidant activity, among others). At present, nevertheless, textiles from agro-residues do not completely meet the requirements to make them an attractive replacement for conventional fibre sources. Future research should therefore focus on identifying new agro-residue based blends that offer both performance and sustainability, adopting a systemic design approach based on interdisciplinary and interconnections as a strategy for innovation.

The agricultural operations in India are suffering from a serious problem of shortage of electrical power on one side and economic and effective disposal of agriwaste stuff on the other. India being agriculture based country, 70% of its main income (share in GDP) comes from agriculture sector. Any enhancement of income from this sector is based upon adequate supply of basic inputs in this sector. Regular and adequate power supply is one such input. But, the position of power supply in our country defies both these characteristics. With a major portion of power produced being sent to the industrial and urban consumers, there is a perennial shortage of power in the agriculture sector. Consequently, there is an emergent need to produce more power in order to fulfil the needs of this sector effectively. One way of accomplishing this is setting up captive, preferably rural based, small power generation plants. In these power plants, instead of water-head, diesel oil or coal, we can use agri-residue to produce electricity. One such power plant (1–2 MW capacity) can satisfy the power need of 25 to 40 nearby villages. The agriwaste like rice straw, sugarcane-trash, coir-pith, peanut shells, wheat stalks & straw, cottonseed, stalks and husk, soyabean stalks, maize stalks & cobs, sorghum. Bagasse, wallnut shells, sunflower seeds, shells, hulls and kernels and coconut husk, wastewood and saw dust can be fruitfully utilized in power generation. This stuff is otherwise a waste and liability and consumes a lot of effort on its disposal; in addition to being a fire and health hazard. Agriwaste stuff which at present is available in abundance and prospects of its utilization in producing energy are enormous. This material can be procured at reasonably low rates from the farmers who will thus be benefited economically, apart from being relieved of the responsibility of its disposal. Agri-residue has traditionally been a major source of heat energy in rural areas in India. It is a valuable fuel even in the sub-urban areas. Inspite of rapid increase in the supply of, access lo and use of fossil fuels, agri-residue is likely to continue to play an important role, in the foreseeable future. Therefore, developing and promoting techno-economically-viable technologies to utilize agri-residue efficiently should be a persuit of high priority. Though there is no authentic data available with regard to the exact quantity of agricultural and agro-industrial residues, its rough estimate has been put at about 350 mt per annum. It is also estimated that the total cattle refuse generated is nearly 250 mt per year. Further, nearly 20% of the total land is under forest cover, which produces approximately 50 mt of fuel wood and with associated forest waste of about 5 mt.(1). Taking into account the utilization of even a portion (say 30%) of this agri-residue & agro-industrial waste as well as energy plantation on one million hectare (mha) of wastelands for power generation through bioenergy technologies, a potential of some 18000 MW of power has been estimated. From the foregoing, it is clear that there is an enormous untapped potential for energy generation from agri-residue. What is required is an immediate and urgent intensification of dedicated efforts in this field, with a view to bringing down the unit energy cost and improving efficiency and reliability of agri-waste production, conversion and utilisation, leading to subsequent saving of fossil fuels for other pressing applications. The new initiatives in national energy policy are most urgently needed to accelerate the social and economic development of the rural areas. It demands a substantial increase in production and consumption of energy for productive purposes. Such initiatives are vital for promoting the goals of sustainability. cleaner production and reduction of long-term risks of environmental pollution and consequent adverse climatic changes in future. A much needed significant social, economic and industrial development has yet to take place in large parts of rural India; be it North, West, East or South. It can be well appreciated that a conscious management of agri-residue, which is otherwise a serious liability of the farmer, through its economic conversion into electric power can offer a reasonably viable solution to our developmental needs. This vision will have to be converted into a reality within a decade or so through dedicated and planned R&D work in this area. There is a shimmering promise that the whole process of harvesting, collection, transport and economic processing and utilisation of agri-waste can be made technically and economically more viable in future. Thus, the foregoing paras amply highlight the value of agri-residue as a prospective source of electric power, particularly for supplementing the main grid during the lean supply periods or peak load hours and also for serving the remote areas in the form of stand-alone units giving a boost to decentralised power supply. This approach and option seems to be positive in view of its potential contribution to our economic and social development. No doubt, this initiative needs to be backed and perused rigorously for removing regional imbalances as well as strengthening National economy. This paper reviews the current situation with regards to generation of agriwaste and its prospects of economic conversion into electrical power, technologies presently available for this purpose, and the problems faced in such efforts. It emphasizes the need for an integrated approach to devise ways and means for generating electrical power from agriwaste; keeping in mind the requirements of cleaner production and environmental protection so that the initiative leads to a total solution.

TMG Research gGmbH aims to help develop a more systematic understanding of how agri-food systems can be transformed as part of a project on the Assessment and Communication of Climate Impacts of Food (CLIF), funded through the International Climate Initiative (IKI) of the German Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) and jointly implemented with corsus and WWF Germany. This project promotes sustainable consumption patterns and helps companies, policymakers, and consumers choose more sustainable options in relation to food. The main contribution of TMG to this project is in developing a more systematic understanding of how to transform agri-food systems by publishing a series of strategic reports on the current status of agri-food systems and the likely drivers and agents of their transformation. This report is part of the FORESEE (4C) series on The Transformation of Agri-Food Systems in Times of Multiple Crises, which explores the status quo of the current agri-food system in the light of challenges linked to the multiple crises. This part of the series reviews the blind spots and gaps in the debate around agri-food systems transformation and how these hinder the transformation. Furthermore, this report offers recommendations on how to address these gaps to facilitate an agri-food system transformation aligned to the leading themes of people, planet, and prosperity. The report was drafted by TMG with contributions from an extended group of experts.

The main contribution of TMG to this project is in developing a more systematic understanding of how to transform agri-food systems by publishing a series of strategic reports on the current status of agri-food systems and the likely drivers and agents of their transformation. This report is part of the FORESEE (4C) series on The Transformation of Agri-Food Systems in Times of Multiple Crises, which explores the current agri-food system in light of challenges linked to the four crises known as the 4 Cs (Climate, Covid-19, Conflict, and Cost of externalities). This part of the series reviews the state of the debate around agri-food systems transformation from the perspective of different organisations that represent a wide range of actors and stakeholders. Furthermore, this report provides an overview of the different proposed approaches to achieving the goals of agri-food system transformation aligned to the themes of people, planet, and prosperity. The report was drafted by TMG in consultations with an extended group of experts.
