A melhoria das condições de vida é o objetivo principal da migração individual, mas seu resultado pode ser o oposto. Esta dissertação estuda as implicações da migração em duas distintas e importantes literaturas. A tradição do Federalismo Fiscal sugere que a migração pode levar à ampliação das disparidades regionais. Em muitos casos, a ação individualmente racional é coletivamente irracional, resultando em pior qualidade de vida para o imigrante. A Nova Geografia Econômica sugere que a migração funciona para quem migra, mas pode novamente resultar em aumento das disparidades regionais. A partir da crítica a alguns dos pressupostos destas duas teorias, é apresentado um modelo em que a migração aumenta a desigualdade na região de atração, devido à desigual propriedade da terra. / The improvement of living standards is the main objective of individual migration, but its results can be opposite. This dissertation studies the implications of migration in two distinct and important literatures. The Fiscal Federalism tradition suggests that migration can lead to severing regional and social disparities. In many cases, the individually rational decision is collectively irrational, resulting in a worse living standard for the immigrant. The New Economic Geography suggests that migration do work for the migrating people, but still can result in an increase in regional disparities. After some critiques to assumptions and hypotheses of those two theories, it is presented a model in which the migration increases inequality in the attractive community because of the land ownership.

I examine whether policies that specifically target gender inequality improve the well-being of women and girls. In the first paper I study the impact of Ethiopia’s gendered land certification programs on household consumption patterns and infant and under-five mortality. After years of communism during which all land was nationalized, in 1998, Ethiopia embarked on a land tenure reform program. The reform began in Tigray region where land certificates were issued to household heads, who were largely male. In a second phase carried out during 2003-2005, three other regions, Amhara, Oromia, and SNNP, issued land certificates jointly to household heads and spouses, presenting variation in land tenure security by gender. I leverage this variation in land certification across regions and over time, to study whether inclusion of women yielded different effects. Using data from the Ethiopia Demographic and Household Surveys and longitudinal data from the Ethiopia Rural Household Survey I construct a treatment group of male-headed households in joint land certification regions and a comparison group of male-headed households in Tigray and study changes between the two groups after implementation of their respective land certification programs. I find that, compared to household-head land certification, joint certification was accompanied by increased household consumption of food, health care, women’s clothing, and girls’ clothing, and a decrease in girls’ infant and under-five mortality. These effects are largely restricted to households with illiterate mothers indicating that inclusion of women in land tenure reform empowered previously disempowered women who then used their improved position to allocate more household resources to their daughters. In the second paper, I examine the relationship between women's land ownership and participation in transactional sex, multiple sexual partnerships and unprotected sex, and HIV infection status. Using a sample of 5,511 women working in the agricultural sector from the 1998, 2003 and 2008–09 Kenya Demographic and Health Surveys, I find that women's land ownership is associated with fewer sexual partners in the past year and lower likelihood of engaging in transactional sex, indicators of reduced survival sex, but is not associated with unprotected sex with casual partners, indicating no difference in safer sex negotiation. Land ownership is also associated with reduced HIV infection among women most likely to engage in survival sex, i.e., women not under the household headship of a husband, but not among women living in husband-headed households, for whom increased negotiation for safer sex would be more relevant. The third paper examines the prevalence of son preference in families of East and South Asian origin living in the United States by investigating parental time investments in children using American Time Use Surveys. The results show that East and South Asian mothers spend more total time and more quality time with their young (aged 0-5 years) sons than with young daughters while fathers’ time with young children is gender neutral. I find gender specialization in time with children aged 6-17 with fathers spending more time with sons and mothers spending more time with daughters. These findings document health and social consequences of gender inequities within households. The findings also highlight that gender-sensitive policies have the potential to transform intrahousehold dynamics and help realize gender equality policy objectives.

Fuelwood is a basic need for rural households in Malawi. However, deforestation has reduced the quantity of forest products such as fuelwood available to households. This has negatively affected rural Malawian quality of life, especially for women who are forced to walk long distances to collect fuelwood, prepare foods with short cooking times, or reduce the number of meals. The Malawi government has encouraged the establishment of household owned woodlots, as a part of reforestation programs, to address the supply side of the forest product scarcity. However, fuelwood supply and use is also a gender-based issue; men plant trees and make decisions over harvesting, while women gather and use fuelwood. Within the household, woodlot products also have multiple and competing uses between men and women. It is critical to examine how gender dynamics affect women's fuelwood procurement and use from the woodlot. This study investigated how gender of the household head and women's access to woodlots affects fuelwood shortage, controlling for number of trees, household size, and use of other fuels. Fifty-one female and sixty-three male-headed households with household owned woodlots were interviewed, using questionnaire and focus group interviews. Results show that one-third of both household types reported experiencing fuelwood shortages in the past year. Logistic regression indicates that gender of household head is an important factor, along with number of trees in the woodlot, in determining fuelwood sufficiency. Female-headed households were less likely to experience fuelwood shortage than male-headed households when the interaction with number of trees was included. Whether a woman in male-headed households must seek permission to harvest fuelwood, number of trees, and cooking with maize stalk were factors that predicted fuelwood shortage. Suggestions for several interventions to address fuelwood supply and access were included. Planting more trees in woodlots and use of fuelwood efficient stoves are two important strategies. It is important to address gender-specific priorities as they relate to woodlot use. This can be done through gender sensitizations that target program planners and male household heads. For successful programs, men and women should participate in both program planning and implementation. / Graduation date: 2003

This dissertation consists of three essays on private landowners' response to incentives for carbon sequestration in forests. The first essay examines private landowner response to incentives for carbon sequestration through various combinations of intermediate management practices. The second essay focuses on agricultural landowners' willingness to participate in an incentive program for carbon sequestration through afforestation, and estimates the potential for carbon sequestration from afforestation, as well as its cost. The third study examines relative performances of incentive targeting strategies for forest carbon sequestration under asymmetric information given spatially heterogeneous land types. The first essay uses an econometric approach to analyze the factors affecting non-industrial private forest landowners' choice of forest management practices, and examines how these choices might change in response to the use of incentives for carbon sequestration. I use estimated parameters to simulate the carbon sequestration potential for different combinations of management practices, and compare the effectiveness and costs of performance-based and practice-based incentive payment schemes in the Western U.S. The results suggest that incentive payments can increase the probability that desirable combinations of management practices are adopted, and particularly that incentives targeting increased fertilization yield the highest carbon sequestration potential. I also find that a performance-based payment scheme produces higher carbon sequestration than a practice-based payments scheme. However, the annual sequestration potential of intermediate forest management in response to incentive payment is not as large as the sequestration potential of afforestation. The second essay uses a survey-based stated preference approach to predict landowners' willingness to participate in a tree planting program for carbon sequestration as a function of various factors affecting landowners' decision making and different levels of incentive payments. The estimation results show that the annual payment for carbon sequestration significantly and positively affects landowners' stated level of enrollment in a tree planting program. I use the estimated parameters to conduct regional level simulations of carbon sequestration in response to incentive payments. These simulations show that the carbon supply function in the Pacific Northwest region is steeper than in the Southeast region because of the lower adoption rate and less available lands. The national level carbon supply functions derived from this study are steeper than those obtained from bottom-up engineering approaches and optimization models, and are in the same range as those from revealed preference approach studies. The third essay uses both a conceptual analysis and a numerical analysis to examine the relative performances of incentive programs for carbon sequestration using alternative targeting criteria in the presence of asymmetric information and heterogeneity in costs and benefits. The results show that in the presence of asymmetric information, the combination of high cost-high benefit variability and negative correlation, which is the combination that achieves the greatest benefit gains under perfect information, can result in the greatest benefit losses. Additionally, a comparison of two targeting schemes shows that if cost variability is greater than benefit variability with negative correlation, the benefit achieved under benefit-cost ratio targeting can be lower than that under acreage targeting, so that an optimal targeting strategy under perfect information may no longer be optimal under asymmetric information. / Graduation date: 2013

Por estratégias se entende o conjunto das práticas pelos quais os indivíduos ou grupos de indivíduos procuram manter ou melhorar sua posição na estrutura social. Trata-se de desvendar as práticas através das quais este setor social busca conservar ou ampliar seus diferenciais de poder em relação aos demais agentes do espaço social, assim como o feixe de condições sociais em que elas ocorrem. A história de ocupação contemporânea do território deste estado, marcada por grandes propriedades de criar nas suas áreas de campos e pela instalação de colônias de imigrantes europeus em áreas de florestas, sobretudo de alemães e italianos, determinou influências mútuas quanto à dinâmica dos poderes exercidos nestes espaços sociais. No espaço estancieiro houve um duplo bloqueio aos setores subordinados relativo ao impedimento de migrar para as áreas de matas, devido à instalação das colônias, e à impossibilidade de migrações coletivas ao trabalho industrial devido à preferência do braço imigrante, ao menos até meados de 1950, e das dinâmicas de desenvolvimento das regiões coloniais que fazia ampliar a concorrência pela oferta de mão de obra nas áreas industriais. Esses efeitos, somados aos da Lei de Terras de 1850, aos cercamentos dos campos, à força e violência na apropriação privada da terra, determinaram a estrutura de poderes assimétricos na qual os estancieiros desenvolveram relações de dominação personalizada em relação à força de trabalho em seus domínios até o início da década de 1990. Externamente à estrutura de dominação do espaço estancieiro, a complexidade das relações entre os grupos dominantes no espaço estadual e nacional promoveu uma grande transformação da elite estancieira a partir de meados de 1940: deixar de ser subsidiária às lavouras de exportação do Nordeste açucareiro e do Sudeste cafeeiro, para se tornar produtora de um artigo de luxo, a carne frigorificada, a partir de uma rede de frigoríficos por eles coordenada. A trajetória de ascensão coletiva da elite estancieira, devido, sobretudo, à valorização do preço dos gados, se dá até o final da década de 1980, quando a baixa dos preços dos gados provoca a quebra de seus frigoríficos, havendo maior pressão para reconversão de trajetórias a partir de então. Essa história objetivada também determinou uma história incorporada na forma habitus, em termos de princípios de visão e divisão do mundo, comportamentos e disposições sociais que são externalizadas em suas práticas, além dos investimentos e cálculos específicos não somente relativos aos propriamente econômicos, mas também em termos de acúmulo de capitais sociais e culturais. À decadência relativa que se inicia a partir de meados de 1990, que é de seu capital social, além do econômico, processa-se um descompasso e inaptidão de seus habitus frente ao que é exigido em termos de disposições sociais pelas alterações que ocorrem no espaço social e, grosso modo, pela sociedade em geral / Abstract: The present thesis analyzes the strategies of social reproduction of the large landowners breeders in Rio Grande do Sul from the establishment of the Republic, whose domain is conventionally called ranches and ranchers their masters. The strategies are meant the set of practices by which individuals or groups of individuals seek to maintain or improve their position in the social structure. It means to unveil the practices through which this social sector or expanding your search conserve power differentials in relation to other agents of social space, as well as the bundle of social conditions in which they occur. The contemporary history of occupation of the territory in this state is marked by great estates created in their areas of fields and installation of colonies of European immigrants in forest areas, especially Germans and Italians, established mutual influences on the dynamics of these powers exercised in social spaces. Within rancher's domain there was a double lock on the subordinate sectors as an impediment to migrate to areas of forests, due to the installation of the colonies, and the impossibility of collective labor migration due to the branch of the industrial immigrant preference, at least until mid-1950, and the dynamics of development of the regions that made colonial increase competition by offering labor in industrial areas. These effects, together with the Land Law of 1850, the enclosure of the fields, to force and violence in the private appropriation of land, determined the structure of power in which ranchers had asymmetrical customized relations of domination developed in relation to the workforce in their fields until the early 1990s. Externally the structure of domination of rancher's space, the complexity of the relationships between dominant groups within state and national organized a major transformation of rancher's elite from mid-1940: stop being subsidiary to export crops of sugar from Northeast and coffee from Southeast, to become producing a luxury, meat cold storage, from a network of refrigeration coordinated by them. The trajectory of collective rancher's elite rise, mainly due to the appreciation in the price of cattle, occurs until the late 1980s, when lower prices for cattle causes the breakdown of their refrigerators, with greater pressure for conversion of trajectories since then. This story objectified also determined a corporate history as habitus, in terms of principles of vision and division of the world, social behaviors and dispositions that are outsourced in their practices, in addition to investments and specific calculations not only for the specifically economic, but also in terms of accumulation of social and cultural capital. The relative decadence that begins from mid 1990, which is its capital, beyond the economic processes are a mismatch and ineptitude of their habitus forward to what is required in terms of social provisions for changes that occur in social space and roughly by society in general / Doutorado / Ciencias Sociais / Doutor em Ciências Sociais

This study sought opportunities to mitigate the pressures of land transformation and alien invader plants on commercial farm land in the thicket biome in the lower reaches of the Fish Kowie Corridor. It had two aims. Firstly, to determine the role incentives could play in mitigating these pressures. Secondly, to determine the characteristics of an incentive programme that would most effectively achieve this. In order to do this, an understanding of landowner activities, needs, opinions and barriers to behaviour; the nature of the pressures on thicket and the nature of the required behaviour to reduce these pressures; and current and past institutional arrangements needed to be achieved. This was done predominantly through a current literature review and personal interviews with landowners and key informants. These findings were used to make recommendations for an effective incentive programme. Landowners showed a preference towards tangible incentives, in particular management assistance, financial compensation and law enforcement. They indicated an aversion to an incentive programme implemented by a government agency, particularly district and provincial government. Rather, landowners showed a propensity towards a nongovernment organisation (NGO) or a farmers group implementing an incentive programme. It was recommended that the two major pressures, namely land transformation and alien invader plants, required different interventions by different agencies in order to be mitigated. The pressure of land transformation required a stewardship model response, with the primary drive being a non-contractual environmental extension service to landowners. The extension service should focus on promoting pro-conservation practises, raising awareness and disseminating information. It should also build a relationship of trust between landowners and the implementing agency. The pressure of alien invader plants would be most effectively addressed through the Working for Water programme. Tangible incentives must be provided to the landowner to induce the costly exercise of alien invader plant control. In particular, the high cost of labour must be addressed. The regulatory incentive of applying laws requiring landowners to control alien invader plants on their land should also be enforced.

Thesis (LLM (Public Law))--University of Stellenbosch, 2009. / ENGLISH ABSTRACT: The first part of this thesis deals with the right of lateral and subjacent support and explains how it should be applied in South African law. The thesis illustrates how the neighbour law principles of lateral support were incorrectly extended to govern conflicts pertaining to subjacent support that arose in South African mining law. From 1911 right up to 2007, these two clearly distinguishable concepts were treated as synonymous principles in both academic writing and case law. The thesis plots the historical development of this extension of lateral support principles to subjacent support conflicts. In doing so, it examines the main source of South Africa’s law of support, namely English law. The thesis then shows how the Supreme Court of Appeal in Anglo Operations Ltd v Sandhurst Estates (Pty) Ltd 2007 (2) SA 363 (SCA) illustrated how the English law doctrine of subjacent support, with all its attendant ramifications, could not be useful in resolving disputes that arise between a land surface owner and a mineral rights holder in South African mining law. The second of half of the thesis investigates the constitutional implications of the Supreme Court of Appeal’s decision in Anglo Operations in light of the systemic changes introduced by the Minerals and Petroleum Resources Development Act 28 of 2002. In terms of this new Act, all the mineral and petroleum resources of South Africa are the common heritage of the people of South Africa, and the state is the custodian thereof. This means that landowners are no longer involved in the granting of mineral rights to subsequent holders. In light of the Anglo Operations decision, landowners in the new dispensation of mineral exploitation face the danger of losing the use and enjoyment of some/all their land. The thesis therefore examines the implications of the statutory provisions in South African legislation (new and old) that have/had an impact on the relationship between landowners and mineral right holders with regard to the question of subjacent support, as well as the implications of the Anglo Operations decision for cases where mineral rights have been granted under the statutory framework. / AFRIKAANSE OPSOMMING: Die eerste deel van die tesis handel oor die reg op sydelingse en oppervlakstut en hoe dit in die Suid-Afrikaanse reg toegepas behoort te word. Die tesis wys hoe die bureregbeginsels rakende sydelingse stut verkeerdelik uitgebrei is na konflikte rakende oppervlakstut wat in die Suid-Afrikaanse mynreg ontstaan het. Vanaf 1911 en tot in 2007 is hierdie twee duidelik verskillende konsepte in sowel akademiese geskrifte en in die regspraak as sinonieme behandel. Die tesis sit die historiese ontwikkeling van die uitbreiding van laterale stut-beginsels na oppervlakstut-konflikte uiteen. In die proses word die hoofbron van die Suid-Afrikaanse reg ten aansien van steun, naamlik die Engelse reg, ondersoek. Die tesis wys uit hoe die Hoogste Hof van Appèl in Anglo Operations Ltd v Sandhurst Estates (Pty) Ltd 2007 (2) SA 363 (SCA) beslis het dat die Engelse leerstuk van oppervlakstut met al sy meegaande implikasies nie in die Suid-Afrikaanse reg sinvol aangewend kan word om dispute wat tussen die oppervlakeienaar van grond en die mineraalreghouer ontstaan, op te los nie. Die tweede helfte van die tesis ondersoek die grondwetlike implikasies van die Hoogste Hof van Appèl se beslissing in Anglo Operations in die lig van die sistemiese wysigings wat deur die Wet op Ontwikkeling van Minerale en Petroleumhulpbronne 28 van 2002 tot stand gebring is. Ingevolge die nuwe Wet is alle mineraal- en petroleumhulpbronne die gemeenskaplike erfenis van alle mense van Suid-Afrika en die staat is die bewaarder daarvan. Dit beteken dat grondeienaars nie meer betrokke is by die toekenning van mineraalregte aan houers daarvan nie. In die lig van die Anglo Operations-beslissing loop grondeienaars die gevaar om die voordeel en gebruik van al of dele van hulle grond te verloor. Die tesis ondersoek daarom die implikasies van verskillende bepalings in Suid-Afrikaanse wetgewing (oud en nuut) wat ‘n impak op die verhouding tussen die grondeienaar en die houer van die mineraalregte het, sowel as die implikasies van Anglo Operations vir gevalle waar mineraalregte onder die nuwe statutêre raamwerk en toegeken is.
