Herd management and livestock productivity in the Altai region of Western Mongolia

This thesis analyses the influence of qualitative and quantitative herbage production on seasonal rangelands, and of herd and pasture use strategies on feed intake, body mass development and reproductive performance of sheep and goats in the Altai mountain region of Bulgan county (soum) in Khovd province (aimag). This westernmost county of Mongolia is characterized by a very poor road network and thus very difficult access to regional and national markets. The thesis explores in this localized context the current rural development, the economic settings and political measures that affect the traditional extensive livestock husbandry system and its importance for rural livelihoods. Livestock management practices still follow the traditional transhumant mode, fully relying on natural pasture. This renders animal feeding very vulnerable to the highly variable climatic conditions which is one of many reasons for gradually declining quantity and quality of pasture vegetation. Small ruminants, and especially goats, are the main important species securing economic viability of their owners’ livelihood, and they are well adapted to the harsh continental climate and the present low input management practices. It is likely that small ruminants will keep their vital role for the rural community in the future, since the weak local infrastructure and slow market developments currently do not allow many income diversification options. Since the profitability of a single animal is low, animal numbers tend to increase, whereas herd management does not change. Possibilities to improve the current livestock management and thus herders’ livelihoods in an environmentally, economically and socially sustainable manner are simulated through bio-economic modelling and the implications are discussed at the regional and national scale. To increase the welfare of the local population, a substantial infrastructural and market development is needed, which needs to be accompanied by suitable pasture management schemes and policies

U.S. Highway 20 Corridor Development Study, 1992

This study examines the feasibility of making a major financial investment in the improvement of U.S. 20 between Sioux City and Fort Dodge, Iowa. This 119-mile (191-km) highway segment of U.S. 20 currently includes 97 miles (156 km) of 2-lane highway and 22 miles (35 km) of 4-lane highway (on the west end near Sioux City and a short section near Holstein). This 119-mile (191-km) segment is predominantly rural in nature, and serves a region of Iowa that has not been economically prospering. Local business leaders and residents have long desired major improvements to this highway segment, not only because of the safety and travel efficiency implications, but also because of the belief that the highway, as mainly a two-lane facility, is retarding the corridor area's economic growth and well being. The study was divided into five sequential tasks: (A) Evaluation of Existing U.S. 20; (B) Improvement Alternatives, Costs and Traffic; (C) Screening of Alternative Candidate Improvements; (D) Economic Feasibility Analysis; and (E) Interpretation and Comparisons.

Proposta de uma matriz de indicadores de sustentabilidade para Estarreja

Esta dissertação centra-se na elaboração de uma proposta de matriz de indicadores de sustentabilidade a aplicar ao município de Estarreja. Apesar dos mais recentes desafios e requisitos em matéria de monitorização de planos, projectos e actividades com implicações sobre o ambiente e a sustentabilidade, o acompanhamento da evolução económica, social e ambiental, de uma forma integrada, pelo município tem sido escasso. A literatura da especialidade bem como diversas experiencias municipais nacionais e internacionais têm revelado que a adopção de sistemas de indicadores de sustentabilidade tem um grande potencial não apenas para avaliar o progresso dos municípios em direcção à sustentabilidade ambiental, mas também para induzir melhores formas de governação local. O principal objectivo desta dissertação é a construção de uma matriz de indicadores que avalie a sustentabilidade do município de Estarreja ao nível ambiental. A metodologia adoptada neste trabalho consiste em cinco fases, sendo a primeira fase, a revisão da literatura, através da análise de artigos científicos da especialidade. Na segunda fase é feito o enquadramento legislativo das responsabilidades de monitorização ambiental que cabem aos municípios portugueses. Numa terceira fase, desenvolve-se o levantamento e análise de indicadores sectoriais existentes, já recolhidos e tratados por instituições do Concelho de Estarreja. Na quarta fase procede-se à construção da matriz de indicadores de sustentabilidade, agregando os indicadores já recolhidos pelas iniciativas municipais a um novo conjunto de indicadores de sustentabilidade capazes de analisar a evolução do município no que respeita às pressões sobre o ambiente e sobre os níveis de qualidade ambiental. Na quinta fase são apresentadas as principais conclusões do trabalho e feitas recomendações para tornar exequível e eficiente a monitorização da matriz. O trabalho está organizado em cinco capítulos sendo estes coincidentes com as cinco fases da metodologia. A região de Estarreja tem implantado no seu concelho um dos maiores complexos industriais do país e, em consequência disso, tem vindo a sofrer ao longo dos anos o impacto das actividades industrial e urbana. O procedimento para a construção do sistema de indicadores, bem como a identificação dos eixos temáticos necessários para descrever o contexto que influencia a sustentabilidade do desenvolvimento local, teve por base outros sistemas de indicadores de sustentabilidade local e fornece uma ampla avaliação das características ambientais do município. As dimensões ambientais incluem água, gestão de resíduos, solos, ruído, protecção da natureza, biodiversidade, qualidade do ar, energia e espaços verdes e estão distribuídas por 60 indicadores. Entre estes, 32 já estão a ser monitorizados e 28 foram acrescentados no âmbito deste trabalho. A monitorização dos indicadores propostos não exige grande investimento em capital humano e financeiro, no entanto, constitui um desafio, uma vez que pressupõe a interacção, partilha de informação e transparência por parte das diferentes entidades e empresas municipais.

Análise das metodologias de caracterização e delimitação da estrutura ecológica nos planos municipais de ordenamento do território do Alentejo

O estágio realizado teve como objetivo analisar as metodologias de caracterização utilizadas aquando da delimitação da estrutura ecológica municipal de cada concelho alentejano. Propõe-se que este trabalho reflita e sistematize as diferentes perspetivas levadas a cabo na execução dos planos de ordenamento do território (à escala municipal). Pretende-se sobretudo verificar se esta delimitação vai, ou não, ao encontro da perspetiva da Arquitetura Paisagista e de que forma deve esta ser transposta para os processos de planeamento e se cumpre as orientações de carácter geral constantes do PROTA. Hoje em dia, a preservação ambiental já vem sendo considerada uma questão de ordem social, pelo que devemos dirigir--nos para a adoção de um novo padrão de atuação que apreenda o elevado grau de degradação ambiental atual. Este padrão implica o reconhecimento das componentes ambiental, ecológica e paisagística nos processos de planeamento e gestão, fazendo com que a componente ecológica e ambiental seja tida em consideração a par dos elementos construídos e dos económicos e sociais; ABSTRACT: Analysis of Characterization and Delimitation Methodologies of the Ecological Structure in the Municipal Plans for the Alentejo Regional Planning The objective of this internship was to analyze the characterization methodologies during the delimitation of the municipal ecological structure of each county in the Alentejo region. It is proposed that this work reflects and systematizes different perspectives undertaken in the implementation of territory development plans territory (at the municipal level). It is primarily intended to determine if that definition will, or not, meet the perspective of Landscape Architecture and how this should be implemented in the planning processes, and also if that definition follows the general guidelines fixed by the Regional Plan for Spatial Planning of Alentejo. Nowadays, environmental protection has already been considered a matter of social order, thus we must guide ourselves to the adoption of a new standard of performance to seize the high level of current environmental degradation. This pattern implies the recognition of the environmental, ecological and landscape components in planning and management processes, causing ecological and environmental aspects to be taken into consideration alongside the built, economic and social elements.

Papel das medidas agro-ambientais na gestão da paisagem rural no concelho de Marvão no PNSSM

As paisagens rurais portuguesas construídas e mantidas ao longo dos tempos por sistemas agrícolas tradicionais, estão hoje ameaçadas por motivos tão diversos como o envelhecimento da população, o abandono rural, a intensificação, a homogeneização dos sistemas de produção e a perda de competitividade. Mas apesar destes problemas, estas paisagens agrícolas, suportam ainda várias funções não produtivas, nomeadamente, constituem, um importante suporte de biodiversidade, pelo que a sua manutenção é importante para a conservação destes habitats e espécies. Eventualmente novas formas de gestão destas paisagens devem ser criadas, nomeadamente com base na combinação de várias funções numa perspectiva de multifuncionalidade, através de uma adaptação e integração de políticas públicas. Estando actualmente em discussão o novo programa de Desenvolvimento Rural e a definição das futuras Medidas Agro-Ambientais, e a gestão e o financiamento da Rede Natura 2000, estamos portanto num momento crítico para decisões futuras, que terão forçosamente que interligar, a agricultura, o ambiente e desenvolvimento das zonas rurais portuguesas. Com o intuito de melhor compreender estas problemáticas, em particular, as transformações em curso na paisagem rural, o papel das Medidas Agro-Ambientais e apresentar possíveis soluções, foi efectuado este estudo de caso no concelho de Marvão, concelho típico das áreas marginais agrícolas do interior sul de Portugal. ABSTRACT; The Portuguese rural landscapes built up and kept throughout the times by traditional agricultural systems, are today threatened by so diverse reasons as the ageing of the population, the agricultural abandonment, the intensification, the homogenization of the production systems and the loss of competitiveness. But despite these problems. These agricultural landscapes still support a multitude of non-commodity functions, and particularly they still constitute an important support of biodiversity and thus their maintenance is important for the conservation of these habitats and species. Probably new management forms must be created based on the combination of various functions and the adaptation and integration of public policies. Being currently in discussion the new program of Rural Development and the definition of the future Agri-Environmental Measures, and the management and the financing of the Natura 2000 Network, we are therefore at a critical moment for future decisions that will forcibly have to establish connections, between the agriculture, the environment and the development of the portuguese agricultural areas. With the intention of better understanding these problems and questions, , the transformations taking place in Portuguese peripheric rural areas, and in particular role of the Agri-Environmental Measures, and also for presenting possible solutions, a case study was analyzed in municipality of Marvão, characteristic of the agricultural marginal areas of the interior Southern Portugal.

Built heritage-making and socioeconomic renewal in declining rural areas : evidence from Portugal

This article focuses on the connections between built heritage-making and socioeconomic renewal in declining rural areas. Drawing on fieldwork in twelve rural villages in eastern Portugal, it sheds light on the outcomes of a State-led programme, the objectives of which were to renovate the historic built fabric and generate tourism revenue for a region with declining population levels. Overall, the programme was successful in terms of preservation / conservation of monuments and the built fabric, but failed to stimulate the anticipated social and economic development. The conclusion is that the making of heritage spaces is not the remedy for the economic and demographic ills of rural areas, notwithstanding the positive effect that such measures may have in certain cases.

Local productive arrangements for biodiesel production in Brazil: Environmental assessment of small-holders integrated oleaginous crops management.

Sustainability assessments were carried out in small-holders? farms in four territories where productive arrangements have been organized for production of minor oleagi- nous crops under the Brazilian biodiesel program. The study aimed at checking local impacts of the biodiesel productive chains at the rural establishment scale, and pro- moting the environmental performance of the selected farms, henceforth proposed as sustainable management demonstration units. Assessments were carried out with the APOIA-NovoRural system, which integrates 62 objective and quantitative indicators re- lated to five sustainability dimensions: i) Landscape Ecology, ii) Environmental Quality (Atmosphere, Water and Soil), iii) Socio-cultural Values, iv) Economic Values and v) Management and Administration. The main results point out that, in general, the eco- logical dimensions of sustainability, that is, the Landscape Ecology and Atmosphere, Water, and Soil quality indicators, show adequate field conditions, seemingly not yet negatively affected by increases in chemical inputs and natural resources use predicted as important potential impacts of the agro-energy sector. The Economic Values indica- tors have been favorably influenced in the studied farms, due to a steadier demand and improved prices for the oleaginous crops. On the other hand, valuable positive conse- quences expected for favoring farmers? market insertion, such as improved Socio-cultural Values and Management & Administration indicators, are still opportunities to be ma-terialized. The Environmental Management Reports issued to the farmers, based on the presented sustainability assessment procedures, offer valuable documentation and com-munication means for consolidating the organizational influence of the local productive arrangements studied. These productive arrangements were shown to be determinant for the selection of crop associations and diversification, as well as for the provision of technical assistance and the stabilization of demand - conditions that promote value aggregation and income improvements, favoring small-holders? insertion in the market. More importantly, these locally organized productive arrangements have been shown to strongly influence the valorization of natural resources and environmental assets, which are fundamental if sustainable rural development is to take place under the emerging agro-energy scenario.

MIGRATION PATTERNS AMONG YOUNG ADULTS IN THE UNITED STATES: ENVIRONMENTAL, SOCIAL, AND ECONOMIC EXPLANATIONS

Young adult migration is a key factor in community development. The goal of this paper is to study what kinds of places attract young adults and what kinds are losing them. Linear regression is conducted to analyze what place-specific factors explain migration patterns among young adults. These factors include economic, social, and environmental variables. This study finds that social and environmental factors are just as important as economic ones. Specifically, employment in the arts increases young adult net migration. Environmental variables, for example, natural amenities and protected federal lands are particularly important in rural settings in attracting young adults. These findings suggest that policy makers interested in attracting and retaining young adults should pay closer attention to social and environmental factors and consider creating more opportunities for arts employment in general. For rural areas, improving the attractiveness of natural amenities and better protection of federal lands is also recommended.

Young adults’ perceptions of and affective bonds to a rural tourism community

Many rural areas, in Sweden and worldwide, experience population decline where the young leave for education and work in urban areas. Employment has declined in several rural industries, such as agriculture, forestry, and fishing, while growing in other industries are often located in urban areas. Politicians and organizations have put much hope in tourism as a tool of rural development, but can tourism help reverse the rural out-migration trend among young adults? This paper explores how tourism affects young inhabitants’ perceptions of and affective bonds to a rural area in Sweden, the ski resort of Sälen. Students from the 1993–1995 elementary school graduating classes were interviewed about their migration history, childhood, and view of and ties to Sälen. The respondents experience that tourism contributes to a more vital community incorporating influences from elsewhere, but without eliminating the positive aspects of rural life. The regular flow of people – tourists, seasonal workers, and entrepreneurs – passing through Sälen presents opportunities to extend one’s social network that are widely appreciated by respondents. The high in and out mobility constitutes a key part of Sälen’s character. Contributions from tourism – such as employment, entertainment, leisure, and opportunities to forge new social relationships – are available during the adult transition, the life phase when rural areas are often perceived as least attractive. Even though out-migration occurs in Sälen, and some respondents still find Sälen too small, tourism has clearly increased the available opportunities and contributed significantly to making Sälen more attractive to young adults.

Methods of earth building in the Huila Province, Angola

In Angola, the construction made of raw earth is a cultural heritage widely used by low income households, representing over 80% of the population [1, 3]. In Huila province is evident construction in raw earth in a large scale, either in urban or in periurban and rural areas. The construction methods follow the ancestral standards, distributed throughout the region of Huila, being built by the several ethnic groups. Among the construction techniques in earth, stand out: the adobe, wattle-and-daub and more recently on CEB (Compressed Earth Block). The type of soil used to make the adobes is mainly silty-clayed sand [1]. The most applied materials are: rods, reeds, wood, grass, straw, soil and stone, almost with the same characteristics [2]. The manufacture of adobe, consists essentially in mixing clay and grass (plant fibers), then put the mixture inside a wooden mold, having a size of 42 cm long and 18 cm high and taking three to four days to dry and be applied in housing construction. The application of these materials makes the construction less expensive because they are collected, transformed and applied by the owner himself of housing without any project, based only on the result of the practice and experience acquired from their ancestors. They are simple constructions, presenting a typology of grouped and isolated single-family housing, ranging between 2 and 3 bedrooms [2]. The construction techniques used in such small housings have positive environmental aspects, both as regards the materials employed, such as the manner in which the constructions are raised, showing special concerns for the quality improvement of them, as regards the resistance, durability and comfort [4].

Comportamentos lúdicos entre crianças do nordeste do Brasil: categorização de brincadeiras

Este artigo visa categorizar as brincadeiras das crianças de um povoado rural do nordeste do Brasil. Foram observadas individualmente 32 crianças entre dois e 12 anos, de ambos os sexos, brincando em ambiente livre, em sessões de cinco minutos. A categoria de 'brincadeiras simbólicas' foi a mais observada (49%). Os temas das brincadeiras simbólicas estavam predominantemente atrelados ao modo de vida local. Diferenças de gênero foram observadas e analisadas. Os dados sugerem que meninas brincam mais simbolicamente, enquanto as brincadeiras dos meninos são mais variadas. A relação entre brincadeira e contexto baseia-se no aproveitamento das potencialidades que o ambiente oferece para o desenvolvimento da criança caracterizando as relações entre aspectos particulares de cada ambiente e as atividades lúdicas desenvolvidas.
