<p dir="ltr">This dissertation consists of three chapters on economic topics related to spatial, macro, and international economics. In the first chapter, I develop a dynamic spatial general equilibrium model with overlapping generation in which heterogeneous individuals accumulate human capital and move across states. Calibrated to the 2000 U.S. economy, the model illustrates how variations in education efficiency lead to substantial cross-state income disparities and shows that internal migration can notably boost output in states with lower education efficiencies. Applying the calibrated model to analyze the Obama Administration's Race to the Top initiative finds that the initiative increased the U.S. GDP, benefiting the grant-winning states and their neighbors. Strategic reallocation of education grants could further increase national GDP gains without necessarily worsening state income disparities.</p><p dir="ltr">The second chapter of this dissertation is coauthored with Dr. Soojin Kim and Dr. Chong Xiang. We investigate how the China shock affects workers’ health through optimal health investment decisions. We empirically estimate the elasticity of import penetration per worker on future good health probability. In our quantitative evaluation of the China shock, we find that there is little (substantial) change in the probability of future good health of employed workers whose health is initially bad (good), in line with our empirical estimates. In our counterfactuals, we find that universal health insurance would have remedied most of the adverse health effects from the China shock, with large heterogeneity across sickness shocks and across commuting zones with varying degrees of exposure to import penetration.</p><p dir="ltr">The last chapter of this dissertation is coauthored with Dr. Seungyub Han, using regional level data of South Korea. We analyze the effect of conventional land-use restrictions in existing cities as well as the impact of building new cities on undeveloped rural regions, motivated by the South Korean government's 2nd New Town Project (NTP). We estimate the effect of such policies on the aggregate and regional economies, considering both the efficiency gain from the resource reallocation and externalities from regional decline. Our quantification suggests that the NTP promoted economic growth cost-effectively, as it permanently increased the steady state real GDP flow for a one-time building cost. However, it exacerbated regional decline by significantly decreasing the overall rural population.</p>

原住民部落資源自主治理（self-governing）之概念已陸續地推展於原住民地區，過去有關於部落資源自主治理相關議題之討論與研究鮮少從原住民族土地問題切入，少數結合原住民族土地問題與部落資源自主治理者，研究場景也僅著重於原住民族單一族群內的自主治理組織發起與運作過程描述分析，至於在現實政經環境背景下，不同族群間自主治理的過程究竟該如何運作？以及藉由分析其運作過程產生的相關問題，進一步檢視現行原住民族自主治理部落土地資源之政策與地權及地用等相關法令規定者，尚乏相關論著。 本研究選取苗栗縣南庄鄉蓬萊村為實證研究對象，以Elinor Ostrom（1990）所提出的成功自主治理共用資源（common pool resources）八個設計原則（design principles）為檢驗基礎，分析蓬萊溪封溪護魚與八卦力民宿村部落土地資源自主治理制度設計成功與否、歸納制度脆弱或未成功的原因，並且透過社會關係網絡（social context）與取得權（access theory）等相關概念，分析兩案例之社會關係網絡與利益流樣態，以理解制度規範建構之互動過程與核心理由，發掘置於國家權力統治與資本主義貨幣經濟（cash economy）之現實場景下，原╱漢「多族群間」、以及「同族群內部」到「多族群間」自主治理部落土地資源之問題，並指出現行部落自主治理之地用與地權政策規劃與部落現實場景間之差距。 由實證案例分析可知，原住民族傳統部落組織的瓦解與重構過程中，原住民與平地人之間的政經稟賦差異加大，原住民族自主治理之立意往往被扭曲，平地人卻能掌控部落土地資源進而分享大部分之利得。此外，原住民族自主治理部落土地資源之政策走向，忽略漢人使用原住民族傳統領域土地亦有其特殊歷史背景或政策因素，是以在政策層面上當有再深入研究及通盤檢討之必要。而多族群間亦須放棄成見、加強溝通以謀求彼此共識，增加地方自主治理的社會資本，方可妥善管理部落土地資源，朝共同治理之目標邁進。 / The concept of indigenous resources self-governing has been promoted to the indigenous areas one after another. However, there have been few issues and studies about tribal resources self-governing observed from the viewpoint of indigenous land management. Even though minority of issues and studies link up indigenous land problems with tribal resources self-governing, their research background also only puts emphasis on the analysis of a single indigenous race, which describes the establishment of organization and operation for self-governing. How is the self-governing mechanism operated among different races under the realistic political and economical background? How is the self-governing policy of tribal land resources manipulated further? How are laws related to land ownership and land use implemented? All of these topics still lack correlative studies. Therefore, this research takes the tribe of the Penglai Village in Nanjhuang Township Miaoli County as an example, using eight design principles proposed by Elinor Ostrom (1990) to examine the case, which the Penglai stream blocking for fishing resources protection and the self-governing for tribal land resources in the Baguali B&B(bed-and-breakfast) village. The context of illustrations are: (1) analyzing whether the design of institution for the case is successful; (2) inducing the reason why institution is unsuccessful or weak; (3) analyzing the social context and benefit flows of the case to understand the interactive process and the core reason for the establishment of institution standard by the concept of social context and access theory; (4) finding the self-governing problems of tribal land resources among indigenous /Han multi-races(the case of Penglai River) and from one single race to multi-races(the case of Baguali B&B Village) under the realistic background of state right governing and cash economy of capitalism; and (5) pointing out the gap between the current land use and landownership policy plan for tribal self-governing and the realistic situation of tribe. By the analysis of the case, we can find that the disintegration and restructuring of the indigenous tribal organization because of the difference of the political and economical endowment from Han people results in the phenomenon, which the purpose of the indigenous tribe self-governing for land common pool resources has been twisted. In addition, the formulation of the self-governing policy for indigenous land resources ignores that the Han people using the indigenous traditional territory also have its special historical background or resulted from policy implementation. Therefore, it is necessary to study further and overall review, to strengthen the communication to seek a consensus among multi-races and to gain the social capital of local self-governing. In this way, it will be possible to manage the tribal land resources well and achieve the goal of common governance.

L’objectif de la thèse est d’étudier l’insertion des agro-industries dans les territoires et surtoutleur contribution au développement local et régional. Nos recherches ont été effectuées dansle Delta et la basse vallée du fleuve Sénégal (région de Saint Louis du Sénégal). L’étude desentreprises (CSS, SOCAS et GDS) situées dans notre zone d’étude a mis en évidencecertains lieux stratégiques : le Delta et la basse Vallée (espace de production), la région deDakar et l’international comme espace d’approvisionnement et de commercialisation. Cesentreprises contribuent très peu au développement du Delta et de la basse Vallée. Le rôleprépondérant de Dakar au détriment de Saint Louis, les incohérences des politiquesfoncières et de développement régional ainsi que le contexte international et sous-régional(concurrence et fraude) sont autant de facteurs qui expliquent l’impact limité des agroindustriesdans notre zone étude. Notre étude révèle aussi que les prises de terrescristallisent particulièrement des tensions entre les agro-industries et les populations hôtes.D’où la nécessite pour les entreprises d’adopter la politique de RSE, mais aussi pour l’État,de réformer le foncier. La prise en compte des agro-industries dans les plans dedéveloppement local et régional est également une piste à explorer par les élus locaux. / This thesis aims to examine the integration of agricultural industries in the areas andspecifically assess then contribution to the local and regional development. Our research hascovered the Delta and the lower Valley of the Senegal River (the region of Saint Louis ofSenegal). The study of societies (CSS, SOCAS, GDS) located in this area has highlightedcertain strategic places: The Delta and the lower Valley (production area), the region ofDakar and the international market as supplying and marketing area. These societiescontribute very little to the development of the Delta and of the lower Valley. Among thefactors that account for the limited impact of these agricultural industries one can mention theparamount role played by Dakar to the detriment of Saint Louis, the inconsistencies of landand regional development policy as well as the regional an intercontinental context(competition, smuggling). This investigation has also revealed that the appropriation of landsparticularly causes time conflicting relations between agricultural societies and the localpopulations, hence the necessity for these companies to adopt the social responsibility ofcompany’s policy and to reform the land policy. The local councillors should also considertaking into account the agricultural companies in their local and regional development plan.

With the enactment of the Statute of the City (2001), the creation of the Ministry of Cities (2003), the structuring of the National Housing Policy (2004), the National Housing System (2005) and the elaboration of the Housing Plans by the nacional, state and municipal levels, were established the conceptual and instrumental basis for coping with the housing problems in the country. The context created signaled a promising perspective to articulate the land issue to housing policy. Although there is a consensus that urban land is component and an essential condition for the succes of the actions that concretize such a policy, housing practices undertaken rarely deal with this component in the proper way, contributing to worsening socio-spatial inequalities, characteristics of urbanization in the country. This research aims to examine how the feasibility of such land for the production of housing is inserted in the design of housing policies formulated in this context. For the analysis, was chosen a territorial clipping the Metropolitan Region of Campinas, located in the State of S?o Paulo. Housing Plants were analyzed, formulated by the state and metropolitan levels, as well as the Local Plans for Social Housing (PLHIS) of six counties that comprise the region: Americana, Campinas, Indaiatuba, Itatiba, Santa B?rbara d'Oeste and Valinhos. To perform the analysis, three categories were chosen: the framework of housing issues, the land needs of the production of housing policy and strategies proposed action to acquire the land necessary to meet demands. The research showed many "nodes" that influence and characterize the approach to the topic of land in the housing plans, dicussing the obstacles that make the link between land issues and housing policy. / O Brasil evidenciou nas ?ltimas d?cadas importantes transforma??es no campo da pol?tica urbana e habitacional.

No. of bitstreams: 1 Natalia Cristina Tripoli Magalhaes.pdf: 11275908 bytes, checksum: c640dd6ca3f95aaf9702da77824119b0 (MD5) Previous issue date: 2016-02-16 / This Paper aims to understand the production processes of urban space through the articulation between different scales and methods of analysis. As a study of urban configuration, this work not only attempts to analyze the resulting physical aspects, but also the understanding of the processes that forms the urban setting. This regard, it considers social dynamics and advocacy tools applied on urban land related to the use, occupation or processes that push for changes in land value. The urban morphology is related to the absence or presence of urban land policies and other elements that might interfere in the resulting urban form. By that, it is proposed as landscape reading and analysis method of the territory the identification of homogeneous regions, recognized for containing similar socio-spatial characteristics, called here as "morpho-territorial units". The adoption of a new term, justified through the paper, aims to make clear the methods and categories of analysis adopted. Take as territorial clipping the Metropolitan Region of Campinas (RMC), whose has the characteristic of an intense process of fragmentation and urban sprawl. The paper developed a summary table that explicit characteristics, barriers and potentialities observed in each morpho-territorial unit identified in the RMC. The morpho-territorial units, while distinct, keep some features in common which enables the organization through "types" and groups. Mapping is the instrument used to perform spatial analyzes. Made the analysis in the metropolitan scale, the research has selected a particular morpho-territorial unit, considered representative of the RMC, in order to demonstrate that the exercise of understanding of these peculiarities in the morpho-territorial unit chosen, can, through the proposed method, be applied to any of the morpho-territorial units identified. It aims to understanding the urban form by analyzing the characteristics of the morpho-territorial units. It is believed that the proposed method assists in understanding specificities in the studied territorial clipping in order to guide actions of public management and planning. / O presente trabalho visa a compreens?o dos processos de produ??o do espa?o urbano por meio da articula??o entre diferentes escalas e m?todos de an?lise.

早期農業係臺灣社會經濟發展之基石，各相關農業政策皆以糧食增產為主要目標，後因後期臺灣經濟由農業為主漸漸轉向以工業為主，故在時代變遷下，過去多數文獻指出第一次農地改革強調以「所有權」為中心，成功達到農業生產增加目的，以及Arthur Young之名言「荒漠變花園」，認為「所有權」是激勵農民生產之誘因，在現今都市化擴張及工商業發展的社會背景下，是否仍為當前農地政策之主要思維？實有重新探討之必要。爰此，本研究為探討臺灣農地利用是否仍需存有「所有權」之迷思，嘗試釐清在時代變遷下，農民是否須擁有農地所有權才能激勵農民從事農地利用？或只要能保障農民之投入成本能於未來收益相符，即便是透過使用權方式承租農地亦能激勵農民從事利用？並期能透過財產權觀點分析現行農地利用政策，提供未來農地政策研擬修訂之重要參考依據。 基此，本研究首先整理過去相關文獻及政府統計資料，在此基礎上釐清過去涉及地權政策之農地改革變遷過程，以及臺灣農地利用現況問題，藉以建立後續分析架構。其次，針對宜蘭縣三星鄉農民進行問卷調查，以釐清農民在從事農作過程中，擁有農地所有權對農民之影響情形，並瞭解農民透過購買或承租方式擴大農場經營規模之考量為何。最後，為深入分析及探究問卷調查結果之背後影響因素，本研究再針對中央及地方政府機關行政人員進行訪談，據以進行綜合分析。透過此研究脈絡之探討，本研究獲得之重要發現與結論，茲分述如下。 一、本研究透過實證分析得知，農民擁有農地所有權雖會對農地利用有正面影響，但不必然會直接激勵農民從事農作，仍需視當時的社會制度下，何種行為能夠激勵農民達到行為目標（增加所得），即具有激勵效果。而農民擁有農地使用權，亦能提高從事農地利用意願、激勵努力從事農業生產及維護農地環境，惟因使用權具有期限，故相較於農民擁有農地所有權，在提高農地改良投資及對長期從事農作有幫助兩方面，較無法激勵農民。因此，本研究結論指出過去以所有權為中心之農地政策，因社會變遷結果，不必然須再以所有權為中心，亦能具有激勵農民從事農作生產之效果。 二、依據本研究分析及推論，第一次農地改革之成功，應不能僅歸於創設所有權，而是因為透過政策實施重新界定財產權範圍，並建置財產權之權利及義務關係，故使農民投入之成本與未來收益能相符，願意投入更多的勞力從事農作，進而激勵農民願意努力從事農業生產，而建立第一次農地改革成功基礎。以此觀點亦能說明，第二次農地改革後，即便農民擁有農地所有權，惟因從事農作收益不佳，農民投入之成本於未來並無法充分回收時，則會變相導致農民任其休耕、閒置、消極利用，或是觀望日後農地變更之增值。因此，所有權並非能直接激勵農民從事農地利用，即便農民係透過承租方式擴大農場經營規模，只要能保障農民投入成本能與未來獲得收益相符，皆可激勵農民努力從事農作。 三、經本研究調查發現，由於目前購買農地價格太高，且農民擁有農地所有權與使用權對農地利用激勵效果相似，因此在資金條件不足情況下，透過承租方式取得農地，可減輕農民在資金負擔方面的壓力，實為未來主要擴大農場經營規模之方式。而目前政府所推動之小地主大佃農政策，雖係以承租方式擴大農場經營規模，且施行迄今頗具績效，然其政策績效似有成長趨緩之趨勢，故本研究針對小地主大佃農政策績效成長趨緩之原因進行分析，發現主要因地主願意出租之農地多已經初步釋出、三七五減租政策之持續影響、農民健康保險資格影響農地整合活化、缺乏地緣關係難透過承租農地擴大農場經營規模及特殊農業經營傾向以購買農地擴大農場經營規模等五項原因，可能影響該政策績效有趨緩成長之勢。故本研究基於研究觀察及發現，據以研提五項政策修正建議，包括：1.由於農地多已初步釋出，故應開始從農地規模化轉而思考農地集中化，不再僅追求量的成長；2.透過農地管理中心整合目前委託經營、口頭租約、代耕之擴大農場經營規模方式，不僅以書面契約為必要條件；3.調整農民健康保險之資格條件，不必然以擁有或承租一定農地面積以上為審查必要條件；4.透過現有大佃農師徒學習或是參與學習方式，引領新農民獲得當地農村信任感，順利承租農地；5.獎勵地主及承租人雙方簽訂長期農地租賃契約，以刺激承租人規劃及思考更長期之農地利用等，可供作為政府機關未來進行相關政策修訂及調整之參考依據。

Driven by many factors, the water supply services (streamflow and groundwater) of many rivers in the dryland area of China have declined significantly. This aggravates the inherent severe water shortages and results in increased severity in the water use conflicts that are threatening sustainable development in the region. Innovative strategies towards more water-efficient land management are vital for enhancing water quantity to ensure water supply security. A key step in the successful development and implementation of such measures is to understand the response of hydrological processes and related services to changes in land management and climate. To this end, it was decided to investigate these processes and responses in the upper reaches of the Jing River (Jinghe), an important meso-scale watershed in the middle reaches of the Yellow River on the Loess Plateau (NW China). It has been shown that vegetation restoration efforts (planting trees and grass) are effective in controlling soil erosion on the Loess Plateau. Shifts in land cover/use lead to modifications of soil physical properties. Yet, it remains unclear if the hydraulic properties have also been improved by vegetation restoration. A better understanding of how vegetation restoration alters soil structure and related soil hydraulic properties, such as water conductivity and soil water storage capacity, is necessary. Three adjacent sites, with comparable soil texture, soil type, and topography but contrasting land cover (Black locust forest, grassland, and cropland), were investigated in a small catchment in the upstream Jinghe watershed (near Jingchuan, Gansu province). Seasonal variations of soil hydraulic properties in topsoil and subsoil were examined. Results revealed that the type of land use had a significant impact on field-saturated, near-saturated hydraulic conductivity, and soil water characteristics. Specifically, conversion from cropland to grass or forests promotes infiltration capacity as a result of increased saturated hydraulic conductivity, air capacity, and macroporosity. Moreover, conversion from cropland to forest tends to promote the formation of mesopores that increase soil water storage capacity. Tillage in cropland temporarily created well-structured topsoil, but also compacted subsoil, as indicated by low subsoil saturated hydraulic conductivity, air capacity, and plant available water capacity. An impact of land cover conversion on unsaturated hydraulic conductivities was not identified, indicating that changes in land cover do not affect functional meso- and microporosity. Changes in soil hydraulic properties and associated hydrological processes and services due to soil conservation efforts need to be considered, should soil conservation measures be implemented in water-limited regions for sustaining adequate water supply. To differentiate between the impacts of land management and climate change on streamflow, the variation of annual streamflow, precipitation, potential evapotranspiration, and climatic water balance in a small catchment of the upstream Jinghe watershed (near Pingliang, Gansu province) was examined during the period of 1955 – 2004. During this time the relative contributions of changes in land management and climate to the reduction of streamflow were estimated. A statistically significant decreasing trend of -1.14 mm y-1 in annual streamflow was detected. Furthermore, an abrupt streamflow reduction due to afforestation and construction of terraces and check-dams was identified around 1980. Remarkably, 74% of the total reduction in mean annual streamflow can be attributed to the soil conservation measures. Among various conservation measures, streamflow could be considerably reduced by afforestation and terracing (including damland creation), due to their low contribution to water yield. In contrast, slope farmland and grassland can maintain a certain level of water supply services due to higher runoff coefficients. According to a meta-analysis of the published studies on the Loess Plateau, the impact of changes in land management on annual streamflow appears to diminish with increasing catchment size while the impact of climate change appears uniform across space. This means that there is a dependency between the catchment size and the response of hydrological processes to environmental change. At least at the local scale, it appears that well-considered land management may help to ensure the water supply services. Due to limited surface water availability, groundwater is an essential water source for supporting ecosystem and socio-economic development in the dryland region. However, the groundwater process is susceptible and vulnerable to changes in climate and landscape (i.e., land cover and form) that in turn can result in profound adverse consequences on water supply services in water-limited regions. In addition, an improved understanding of the response of groundwater related processes to natural and artificial disturbances is likely to ensure more secure and more sustainable governance and management of such regions, as well as better options for adapting to climate change. Yet, this topic has seldom been researched, especially in areas that have already experienced large-scale alteration in landscape and are located in dryland regions, such as the Loess Plateau. Therefore, an investigation of the baseflow variation along the landscape change was conducted. The average annual baseflow has significantly decreased at catchment scale during the period of 1962 – 2002 without any obvious significant change in climate. At decadal scale, the reduction accounts for approximately 9% in the 1970s, 48% in the 1980s, and 92% in the 1990s, while the baseflow index declines averaging 5%, 16% and 67%, respectively. All of the monthly baseflow levels dropped at varying rates except in January, among which July was the most severe in terms of both magnitude (-4.17) and slope (-0.09 mm y-1). In perspective of landscape change, landform change (terrace and check-dam) tends to reduce baseflow by reallocation of surface fluxes and retention for crop growth causing limited deep drainage in other areas. Land cover change (i.e., afforestation) reduced the baseflow to a larger extent by enhanced evapotranspiration and thus hampered deep drainage as suggested by the soil moisture measurement underneath. The study indicates that knowledge about baseflow formation on catchment scale needs further improvement. Integrated soil conservation and water management for optimizing landscape structure and function in order to balance soil (erosion) and water (supply) related hydrological ecosystem services is vital. The governing processes to the changes of water-supply-services-related hydrological process (e.g., streamflow) are assumed to be different across space. To this end, the factors controlling streamflow were investigated on both a small and large scale. Streamflow in small catchments was found to be mainly controlled by precipitation and land cover type. On a larger scale, evaporative demand was found to be another additional major driving force. Hydrological modeling is a frequently used tool for the assessment of impacts of land use and climate change on water balance and water fluxes. However, application of the Soil and Water Assessment Tool (SWAT) model in the upstream Jinghe watershed was unsuccessful due to difficulties in calibration. The inability of the SWAT model to take the influence of terraces on steep slopes into consideration and the method how to calculate lateral flow were the main reasons for unsatisfactory calibration, at least for the current version of SWAT used in this study. Alternatively, Budyko’s frameworks were applied to predict the annual and long-term streamflow. However, the effect of changes in land management (e.g., afforestation) on streamflow could not be assessed due to a lack of vegetation factors. Therefore, an empirical analysis tool was derived based on an existing relationship for estimation. This method was found to be the most effective in reproducing the annual and long-term streamflow. The incorporation of temporal changes in land cover and form in the approach enables the estimation of the possible impact of soil conservation measures (e.g., afforestation or terracing). The importance of adaptive land management strategies for mitigating water shortage and securing the water supply services on the Loess Plateau was highlighted. A cross-sectoral view of the multiple services offered by managed ecosystems at different spatial scales under changing environments needs to be integrated to improve adaptive land management policy. In a water limited environment, such as the Loess Plateau, multiple ecosystem services including hydrological services need to be balanced with minimum trade-offs. This can only be achieved when management is based on a holistic understanding of the interdependencies among various ecosystem services and how they might change under alternative land management.

Rural development is a key policy area in developing countries. Its basic premise boils down to improving the economic well-being and quality of life of rural people. Best practices regarding rural development in developing countries, including Benin, China, Korea and Rwanda, that are known to have been relatively successful in reducing poverty and diversifying the rural economy showed that strong governance, institutional capabilities, active rural communities, and most importantly funding, are all essential for successful rural development. Moreover, land reform and investment in agriculture, infrastructure, education and health play a crucial role in the early stages of rural development. The aim of this study was to examine the concept of rural development as well as policy measures and best practices relating to rural development in order to formulate a rural development strategy for the rural areas of Limpopo Province. To achieve its research objectives, the study used a qualitative research method and secondary data analysis. Before 1995, rural development in South Africa was neglected, resulting in underdevelopment and impoverishment in rural areas. Post-1994, policies for rural development were adopted by the democratic government to improve the economic well-being of people living in rural communities. However, this had thus far limited success as high levels of poverty and inequalities in rural areas still prevails. Those highly affected were rural people in Limpopo Province. In 2018, Limpopo was the most predominantly rural province in South Africa, with over 80% of the population living in rural areas. The study classified Limpopo’s local municipalities into three types of areas, namely predominantly rural area (a local municipality is classified as predominantly rural area if the share of rural population in the local municipal area is above 50%), significantly rural area (that is, a local municipality where the share of rural population in the local area represents between 15% and 49% of the local area’s total population), and predominantly urban area (that is, a local municipality where the share of rural population in the local area is below 15%). Out of 25 local municipalities in Limpopo, 19 were predominantly rural areas, five were significantly rural areas and one was predominantly urban area. Findings show that, in rural areas of Limpopo, there was the prevalence of lower-wage jobs, lower educational attainment, a higher share of low-income households, and more than half of the population depended on government's social grants (including old age grant) and remittances as their income sources. Analysis indicates that educational attainment, household income levels, consumption expenditure and investment tend to be relatively lower, while the unemployment rate is higher, in predominantly rural areas. The economic structure is changing as the share of the primary sector in total Gross Value Added (GVA) is slowly declining, while that of the tertiary sector is gradually increasing. Regarding the contributions to the GVA and employment by sector in predominantly rural areas, agriculture contributed less than 3% to the total GVA, yet it is one of the top employers, contributing 13% of employment. Although mining contributed the most (23,7%) to the total GVA, it only employed 4% of the workforce. To address challenges in rural areas, a rural development strategy for Limpopo Province should contain policy tools that will promote infrastructure development for better access to education, communication, transport, safe water and other basic facilities. It should also encourage capital formation in rural enterprises; promote multi-sectoral development involving reviving agriculture, developing tourism and manufacturing sectors; and promote agro-processing and downstream mineral beneficiation; improve support and access to funding for rural enterprises; and promote the development of the green economy to create decent job opportunities. Access to land and land tenure security are a necessity to stimulate investment needed to accelerate rural development. / Economics / M. Com. (Economics)

Therefore, it intends to investigate certain mechanisms which are inserted in planning systems designs and may increase the corrupts transactions in those environments. Through a literature review, seeks to outline elements which would contribute to this dynamic. By an attempt to contextualize forms of territorial control in Brazil, it seeks to understand how ties between state and private actors would operate in the cities. In addition, it discusses how the efficiency of instances of social participation in urban planning processes can be affected by land-use corruption. The work is structured through a case study, which analyzed the dynamics of a urban planning system in a city between 1985 and 2016. Through the survey of the urban legislation and the identification of the actors involved in the processes of urban expansion in the period, it was possible to establish how some elements found in the literature allowed grant of privileges in these processes. / Il presente lavoro cerca di aiutare nella comprensione dei processi di pianificazione e gestione nelle citt? brasiliane. In questo senso, cerca di investigare determinati meccanismi che, inseriti nei sistemi di pianificazione, possono potenzializare le transazioni corrotte in questi ambienti. Attraverso una revisione della letteratura sulla corruzione urbanistica, cerca di delineare quali elementi potrebbero contribuire a questa dinamica. Attraverso uno sforzo per contestualizzare le modalit? di controllo territoriale in Brasile, si cerca di capire come i legami tra attori statali e privati opererebbero nelle citt?. Inoltre, si discute di come l?efficienza delle istanze di partecipazione sociale nei processi di pianificazione e gestione territoriale possa essere influenzata dalla corruzione urbanistica. Per questo, il lavoro ? stato strutturato attraverso un caso di studio, che ha analizzato le dinamiche di un sistema di pianificazione e gestione in una citt? dall?interno dello stato di San Paolo nel periodo 1988-2016. Attraverso il rilevamento della legislazione urbana e l?identificazione degli attori coinvolti nei processi di espansione urbana nel periodo, ? stato possibile stabilire come alcuni elementi trovati in letteratura consentissero l?ottenimento di privilegi in questi processi. / O presente trabalho procura auxiliar na compreens?o de processos de planejamento e gest?o urban?sticos das cidades brasileiras.
