Esta região é reconhecida pelas autoridades administrativas nacionais e provinciais como estando sob pressão de uso agropecuário, desmatamento devido à exploração desenfreada das florestas, queimadas, pecuária extensiva de bovinos e caprinos. Estes fatos estão trazendo e acentuando problemas sócio-ambientais, nomeadamente, insegurança alimentar, baixa produtividade das culturas, erosão e assoreamento dos cursos de água. A avaliação e determinação da capacidade do uso das terras numa bacia hidrográfica são de vital importância para o planejamento e uso racional do solo e outros recursos da terra, dado que o uso inadequado e sem observância da sua capacidade do suporte tem provocado sua degradação. A partir de avaliações dos elementos do meio físico e das atividades desenvolvidas na região compreendidas entre as bacias de Chanagalane e Mazimunhama, com destaque para as de agropecuárias, fez-se uma avaliação das terras, pelo sistema de capacidade de uso, conjugado com as classes de manejo do sistema de aptidão agrícola das terras, a fim de atender ao planejamento e conservação dos recursos da terra e minimizar os problemas ambientais decorrentes do seu uso inadequado. Os dados foram gerados e integrados no SIG Arcinfo/Arcgis 9.2. Os planos de informação para entrada e cruzamento no SIG foram a carta de solos, cartas topográficas (Classes de declives) e uso das terras. Este último componente foi obtido por processamento digital de imagens ASTER. As análises permitiram concluir que a unidades de solos Bv (Basaltos vermelhos) de textura francoargilo- arenoso que ocorrem em declive plano (0-3%) cobrem a maior parte área de estudo com 172.8 km2 (30.1%); este solo foi avaliado como classe IIIs-p/f no sistema de capacidade de uso e 2ab(c) no sistema de avaliação para a aptidão agrícola, mostrando que é um solo adequado para o cultivo de culturas anuais e até perenes, porém têm problemas ligados a profundidade efetiva dos solos e à baixa fertilidade. Por causa da limitante profundidade não é recomendável o uso de mecanização pesada. A segunda unidade de solos que ocupa uma área considerável da área em estudo é a dos solos coluvionares (C) com 154.9 Km2 (26.9%) que ocorrem em relevo suave ondulado a ondulado e estão inclusos na subclasse IVs-sl/so. Estes solos são limitados pela salinidade e sodicidade e risco de inundação. / Abstract: The study area consists of the sub-basins of the Changalane and Mazimunhama rivers, tributaries of the Tembe river, situated in the Maputo province of Southern Mozambique. The region is recognized by the national and provincial authorities as being under pressure from: agricultural use, deforestation due to uncontrolled exploitation of forests, forest fires and the farming of cattle and goats. These factors are creating and exacerbating social and environmental problems, in particular: food insecurity, low crop yields, erosion and siltation of water courses. The evaluation and determination of land use capacity in a hydrographic basin is of vital importance to the planning and rational use of soil and other terrestrial resources given that misuse and disregard of this capacity lead to degradation. From an evaluation of the physical environment and the activities undertaken in the Chanagalane and Mazimunhama basin regions, especially those concerning argiculture, an assessment was made of the land use capability by combining the concepts of system management and agricultural fitness. The purpose of this evaluation was to address the issues of land-use planning and conservation in particular by minimizing the environmental problems arising from misuse. The data were generated and integrated using GIS Arcinfo/Arcgis 9.2. The information layers used included maps of both soil and topography (slope classes) as well a land use map. The latter component was obtained by the digital processing of ASTER images. The analysis showed that the Bv (Basaltos vermelhos) soil units, with a loam-clay-sandy texture, occur on the plains (slope; 0-3%) and cover most of the study area (172.8 km2, 30.1%). This soil was rated as Class IIIs-p/f when evaluated using the land-use capability system 2ab(c), indicating that it is adequate for the cultivation of annual and even perennial crops. However there exist problems regarding the depth of the soil and its low fertility, because of this limited depth it is not recommended to use heavy mechanization. The second soil unit, which occupies a considerable portion of the study area (154.9 km2, 26.9%), consists of the coluvionares soils (C). They occur in regions with mildly to considerably undulating relief and are included in the subclass IVs-sl/so. These soils are limited by their salinity, sodicity and flood risk. / Mestrado / Análise Ambiental e Dinâmica Territorial / Mestre em Geografia

Abstract The research focuses on rural environments and the questions concerning cultural environment surveys in land use planning. The main purpose of the study is to scrutinize how survey information serves planning. The focus is on pointing out the challenges which can be identified in data management and utilization of information. Main challenges are related to the extendedness and increasing workload of surveys, fragmentation of information and the emphasis put on expertise knowledge. The problems are mainly caused by the lack of well-established practical examples, partly on the hegemony of sector based planning and rationalist-comprehensive tradition in theory of science. Yet the surveys form basically the framework, in which the object or area is been reviewed in the preparation phase of planning. In that sense, the chosen methods in fact-finding also define which qualities primarily come into focus. Single methods or viewpoints and the theories they rely on enlighten the whole only in part. On this basis the aims of the study can be divided roughly in three sections – firstly to the critique of the current practices, secondly, conceptual definition of the structural components of the cultural environment itself, and thirdly, formulation of an integrative approach derived from the above mentioned points of departure. The general understanding of the interaction between man, culture and environment is achieved through phenomenological and existential hermeneutics. The person mapping or exploring the environment with his methods is seen as ”link” between the existing conditions and the future plan. Through that, the overall terms of perception and practice-bound preconditions of human interpretation will come under scrutiny. The study aims to ponder the integration of different approaches and angles, forming a ”toolkit” for environmental analytics and interpretation as a kind of a complexity management. Cultural environment surveys should be developed in a way that they would regard areas as thematic and functional entities instead of a sum of single elements. The research results are presented as a matrix of needs-and-goals -analysis, which forms a framework of assessment for values and desicions. The aim is to clarify the general set-up of land use planning which includes various stakeholders and is multidisciplinary by nature, especially in the context of cultural environments. The needs-and-goals -analysis is based on cultural environment profiling, which includes recognition of values and tolerance towards changes. The purpose of an integrative analysis is to bring out development possibilities and restrictions, together with different development goals. The intensions of different stakeholders should be brought out early enough, in order to prevent disagreements to evolve into conflicts and problems. / Tiivistelmä Tässä tutkimuksessa käsitellään maaseudun kulttuuriympäristöjä sekä maankäytön suunnittelun valmisteluvaiheessa tuotettuja kulttuuriympäristöselvityksiä. Tutkimuksessa tarkastellaan, miten suunnittelun tausta-aineistoina toimivat selvitykset ja niiden sisältämä tieto voitaisiin jäsentää palvelemaan paremmin suunnittelua. Tutkimuksessa on pyritty tuomaan esiin haasteita, joita tiedon hallinnassa ja hyödynnettävyydessä suunnittelun pohjaksi on voitu todeta. Pääasiallisesti nämä liittyvät selvitystiedon laajuuteen ja kuormittavuuteen, sektoroitumiseen ja asiantuntijanäkökulman korostumiseen. Tutkimuksessa esille tuodut ongelmat johtuvat osin selkeitten toimintamallien puutteesta, osin sektorisuunnittelun vahvasta taustavaikutuksesta sekä rationalistis-komprehensiivisesta perinteestä tieteenteoriassa. Kaavoituksen valmisteluvaiheen selvitykset muodostavat kuitenkin viitekehyksen, jonka puitteissa suunnittelualuetta tarkastellaan. Siten valitut tiedonhankinnan menetelmät määrittävät mihin ominaisuuksiin tarkastelun fokus ensisijaisesti painottuu. Käytännössä yksittäiset menetelmät tai niiden taustalla olevat tieteenalat valottavat kokonaisuutta kuitenkin vain osittaisesti ja hajanaisesti. Tutkimuksen tavoitteet voidaan jakaa karkeasti kolmeen eri osa-alueeseen - edellä mainittuun nykyisten käytäntöjen kritiikkiin, ilmiöstä itsestään määrittyvien rakennetekijöiden teoreettis-käsitteelliseen määrittelyyn sekä tähän nojautuvan integroivan lähestymistavan muodostamiseen. Tutkimuksessa hahmotellun kokonaiskäsityksen perustana on fenomenologisen ja eksistentiaalisen analytiikan keinoin määritelty ymmärrys ihmisen, kulttuurin ja ympäristön vuorovaikutuksesta. Tarkasteltavana ovat täten havainnoinnin yleiset edellytykset sekä ne käytäntösidonnaiset ennakkoehdot, joiden myötä selvityksen laatija muodostaa tulkintansa. Kulttuuriympäristöä tutkiva ihminen on keinovalikoimineen eräänlainen ”linkki” olemassa olevan ympäristön ja tulevan suunnitelman välillä. Tutkimuksessa on pohdittu eri näkökulmien integroitumista eräänlaiseksi organisoiduksi kompleksisuuden hallinnaksi, jonka perustana on havaintojen tekemisen ”välinekokonaisuus” kohteena olevan ympäristön piirteistä. Selvitysmenetelmiä tulisi kehittää ennen muuta siten, että kulttuuriympäristöjen tarkastelu teemallisten ja toiminnallisten kokonaisuuksien kautta mahdollistuisi nykyistä paremmin yksittäisten kohteitten sijaan. Tutkimuksen tuloksena esitetty tarve- ja tavoiteanalyysi muodostaa tulkintakehyksen suunnitteluvalinnoille ja toisaalta selkiyttää monitoimijaisen ja monialaisen suunnittelun lähtökohtia. Lähtökohtana on kulttuuriympäristöprofiilin laadinta, arvojen ja muutoksensietokyvyn määrittely sekä kehittämispotentiaalien esille nostaminen vaihtoehtoisten kehityspolkujen hahmottamisessa. Eri osapuolten tarpeet ja tavoitteet on myös tuotava esille riittävän aikaisin. Tällä on pyrittävä ennen muuta ehkäisemään ristiriitojen kehittymistä konflikteiksi ja asenteiden lukkiutumista vastakkainasetteluiksi.

It should be noted that Campinas EPA constitutes the preferred site occupation of social segments with higher income, and the illegal subdivisions at the region would have as its goal the production of essential residential and/or leisure activities for these segments. So, the council has levied a firmer stance of the Executive with respect to the division of Campinas EPA rural land, and a more careful application of urbanenvironmental guidelines provided in the Director Plan of the municipality for the referred area. The research is also concerned in examine the general contours of the political relationship between the Executive and the COMDEMA in the construction of urban and environmental policy in Campinas. The central axis of such conflict revolves around the formally existent instruments of participatory democracy and the economic interests of agents connected to the housing market. As a tool for the analysis of such political clashes, we rely primarily on guidelines established by the City Statute, legislation passed in 2001 which gives great importance to the democratic and participatory management of the city / Mestrado / Mestre em Ciência Política

This thesis provides an extensive look at where permitted non-farm uses and dwellings have clustered within Exclusive Farm Use (EFU) zones in the Northern Willamette Valley in Oregon. There is a looming concern that non-farm related uses and dwellings, or non-farm development, are conflicting with agricultural preservation strategies. Specifically, non-farm developments can potentially undermine the critical mass of farmland needed to keep the agricultural economy sustainable, but until now, studies have lacked spatially precise data to systematically track these phenomena. This thesis offers methodological contributions towards analyzing these operations and presents a broad account of what has been occurring in the region. Using permit approval data from the Department of Land Conservation and Development (DLCD) and 2015 county tax lot shapefiles, I geocoded the locations of these uses and dwellings. I used location quotient and spatial autocorrelation coefficients to identify non-farm hotspots in the region and summarized different typologies that have developed. The findings reveal that viticulture operations have amassed near Dundee and Newberg in Yamhill County, while commercial activities and home occupations have clustered near the Salem-Keizer UGB. Concurrently, dwellings have clustered near the Yamhill-Polk County border. Finally, I offer suggestions to improve Oregon's agricultural land use policy and data management process, as well as advocate for more intensive research in the future to generate narratives for our results.

This thesis aIms to produce a distinctive model for the sustainable horticultural development of Maori resources, primarily land. It is inclusive of tikanga Maori and indigenous production systems based on the unique body of knowledge aligned to Maori. The integration of this knowledge with western science is both argued and applied through the model itself. The hypothesis applied was that matauranga Maori relevant to horticulture and pedology can inform and add value to the future development of Maori land resources. The thesis is bui lt on a unique set of contributing knowledge bases aligned to soils and horticultural management supported by three case studies, identified through their common association i.e. whakapapa links. The format of the thesis intentionally follows science principles in structure and presentation and some assumptions are made regarding base knowledge surrounding Maori cultural factors and the science disciplines relative to soils and horticul ture. The indigenous element, including Maori knowledge, is incorporated into the model using a triadic kosmos/corpus/praxis approach. Where kosmos is applied as Te A o Miiori, corpus as miitauranga Miiori and praxis as tikanga Miiori, the relationship between each element is clear and the interpretation of the associated knowledge becomes more apparent and can be applied to cultural assessments of resources, i ncluding land. The crux of the cultural assessment model is the quality of information used to assess Maori resources, especially from the cultural perspective. The Maori cultural paradigm, traditional horticulture and pedology, and various decision systems are purposefully accessed to act as contributors to the assessment model and to highlight the diversity and quality of information land managers have at their disposal. The ability to apply a cultural layer drawn from a body of knowledge not previously included in decision models relative to land utility in New Zealand is the key point. of difference of the model. The model is discussed from the perspective of its beneficial role for future use by Maori and how it can be continuously refined to meet the needs of Maori land owners and thus contribute to the rangatiratanga of Maori.

La major conscienciació actual dels problemes de pol·lució que acompanyen les pèrdues de N del sòl cap a l'atmosfera ha reorientat les investigacions cap a un coneixement més profund dels processos implicats en les emissions dels compostos nitrogenats que comporten un major perjudici des d'un punt de vista ecològic així com els seus principals factors reguladors. La creixent preocupació per l'increment de la concentració atmosfèrica de N2O és deguda a les seves interaccions amb la fotoquímica atmosfèrica i el balanç de radiació de la Terra ja que intervé en la destrucció de la capa estratosfèrica d'ozó, contribueix a l'efecte hivernacle i participa de la pluja àcida. Es considera que els sòls són la principal font de N2O atmosfèric. Al voltant del 90% d'aquestes emissions són d'origen biòtic; els principals processos implicats són la desnitrificació i la nitrificació. L'emissió del N2O produït a través d'aquests dos processos es caracteritza pels diferents nivells de regulació que presenta ja que depèn de la taxa dels processos, de la proporció de N canalitzada per cada procés cap a la producció de N2O i del seu consum dins el mateix sòl el qual està relacionat amb les dificultats en el transport cap a l'atmosfera. Això comporta una gran dificultat a l'hora d'aprofundir en el coneixement de les emissions de N2O del sòl cap a l'atmosfera i de la seva regulació. El desconeixement dels nivells d'emissió de N2O i de la importància de la desnitrificació així com de la seva regulació tant en sòls agrícoles com naturals de les nostres contrades és el principal punt de partida dels objectius d'aquest treball. / The current increased awareness of pollution problems that accompany the loss of soil N to the atmosphere has reoriented research towards a deeper understanding of the processes involved in emissions of nitrogen compounds that lead to greater damage from an ecological point of view as well as their regulatory factors. The growing concern over the increased atmospheric concentration of N2O is due to their interactions with atmospheric photochemistry and radiation balance of Earth as it participates in the destruction of the stratospheric ozone layer, the greenhouse effect and in acid rain. It is considered that the soils are the main source of atmospheric N2O. Around 90% of these emissions are of biotic origin, the main processes involved are nitrification and denitrification. The emissions of N2O produced via these two processes are characterized by different levels of regulation, as it depends on the rate of processes, the proportion of N channeled by each process to N2O production and consumption within the same soil which is related to difficulties in transport to the atmosphere. This entails a great difficulty to deepen the knowledge of soil N2O emissions to the atmosphere and its regulation. The ignorance of N2O emission levels and the importance of denitrification as well as their regulation in both natural and agricultural soils is the main starting point of the objectives of this work.

Com posicionamento distinto, o presente estudo supõe que o MTA constituiu-se por intermédio de um longo processo histórico de mercantilização da terra agrícola, que é anterior à execução daquela PGH. E, mais modernamente, a vigência desta intervenção governamental, num mercado constituído - de fato e de direito - teria provocado uma expansão naquele processo de mercantilização, manifesta, dentre outros fatores, no dinamismo - temporário - dos negócios com terras agrícolas. A fim de realizar esse tipo de discussão, propôs a elaboração de um estudo de caso junto a dois MTAs situados no semiárido nordestino - Assú (RN) e São Rafael (RN) -, por terem sido objeto daquela intervenção governamental hídrica; e, ainda, por terem características físicas e econômicas distintas. Neste último aspecto, dentre os parâmetros de comparação utilizados, cabe mencionar a incidência da desapropriação (comandada pelo Estado) e o desenvolvimento da modernização agrícola (impulsionada pelo mercado e contando com estímulos governamentais). Os dados coletados tanto são primários, quanto secundários. O período amplo de análise do estudo compreendeu os anos de 1971 (tendo em vista a disponibilidade de dados) a 1998 (data de reversão das expectativas positivas de implantação de fruticultura irrigada regional baseada na grande empresa agroexportadora). Dentre os resultados obtidos destacaram-se: a) a mercantilização da terra agrícola e/ou o processo de constituição do MTA ocorreu, seja mediante influência positiva do mercado de produtos agrícolas, seja através de um impulso legal - isto é, com a edição da Lei Estadual de Terras de 1895; b) mais recentemente, a PGH teve início com uma expressiva desapropriação fundiária, que implicou em aumento nos níveis de concentração da base fundiária, previamente existentes; após o término da principal obra hídrica prevista, a Barragem Armando Ribeiro Gonçalves (BARG), registrou-se um crescimento do dinamismo dos negócios no MTA, por um breve tempo, comandado principalmente por agropecuaristas regionais; isto sugeriu um predomínio do uso produtivo da terra (ativo de capital); porém, houve um percentual desse dinamismo comandado por investidores externos ao setor agrícola, num indicativo de que a terra também assumiu uso especulativo (ativo líquido); d) em face da decadência do tradicional complexo econômico nordestino e da pequena expressividade da fruticultura irrigada houve um aumento nos estoques ociosos de terra agrícola, sugerindo que a condição de ativo líquido tornou-se relativamente mais expressiva, do que sugerido anteriormente. Em face dos resultados obtidos concluiu-se que, tal como se supôs, o processo de mercantilização da terra agrícola se consagrou a partir da constituição legal do MTA regional ocorrida a partir do final do século XIX, e, que acompanhou os movimentos do mercado de produtos agrícolas. Modernamente, a PGH dinamizou temporariamente o MTA; de outro, agravou a Questão Fundiária Regional - através de aumento na concentração, ociosidade e especulação com terras agrícolas. Principal solução apontada: efetivação do Imposto Territorial Rural / Abstract: This investigation arose from the questioning in the doctoral dissertation concerning the semi-arid Northeast region of Brazil, the Vale do Açu (RN), between 1979/1983, in which the State, through the Governmental Hydric Policy (PGH), defined and invigorated the Agricultural Land Market (MTA). The present study, taking a specific stance, presupposes that the MTA constituted itself through the mediation of a long historical process of the commodification of agricultural land, which was prior to the carrying out of the PGH. In addition, more recently, the validity of this governmental intervention in the market, by fact and by law, would have provoked an expansion of the commodification process, manifested in the temporary dynamism of business with agricultural lands, among other factors. Aiming to carry out this type of discussion, the development of a case study with the two MTAs located in the semi-arid northeastern region ¿ Assú (RN) and São Rafael (RN) ¿ was proposed, since they were participants in the governmental hydric intervention, and for having distinct physical and economic characteristics. In this latter aspect, among the parameters of comparison used, it is important to highlight the incidence of expropriation of land (ordered by the State, and the development of agricultural modernization (driven by the market and relying on government stimulus). Both primary and secondary data were collected. The broadest period of analysis of this study, spans the years between 1971 (in light of the availability of data) to 1998 (reversion data of the positive expectation of the implementation of regional irrigated fruit crops based on large company agro-exportation models). Among the results obtained, highlighted are: a) the commodification of agricultural land and/or the process of developing the MTA, whether through positive influences from the agricultural product market, or legally driven ¿ with the edition of the State Land Laws of 1895; b) more recently, the PGH¿s initial expressive expropriation, which implicated in the increase of levels of concentration of the previously existing land base; c) after the completion of the main hydric project previewed, the Armando Ribeiro Gonçalves Dam (BARG), growth in the dynamism of business in the MTA was recorded for a brief period, driven mainly by the agricultural-cattle regions; this suggests the predominance of productive land use (active capital); however, there was a percentage of this dynamism driven by foreign investors to the agricultural sector, in an indication that the land was also being used for speculation (active liquid assets); d) facing the decline of the traditional northeastern economic complex, and the low expressivity of the irrigated fruit crop sector, there was an increase in the stocks of unused agricultural land, suggesting that the condition of active liquid assets became relatively more expressive than previously suggested. Considering the results obtained, it is concluded that, as was expected, the process of commodification of agricultural land was consecrated from the legal constitution of the regional MTA, which took place starting at the end of the 19th Century, and, that it followed trends in the agricultural product market. Modernly, the PGH temporarily invigorated the MTA; on the other hand, it disrupted the Regional Landholding Question ¿ through the increase in the concentration, disuse and speculation of agricultural land. The main solution indicated: implementation of the Rural Territory Tax / Doutorado / Desenvolvimento Economico, Espaço e Meio Ambiente / Doutor em Desenvolvimento Economico
