In promoting biodiversity conservation and ecosystem service capacity, landscape connectivity is considered a critical feature to counteract the negative effects of fragmentation. Under a Green Infrastructure (GI) perspective, this is especially true in rural and peri-urban areas where a high degree of connectivity may be associated with the enhancement of agriculture multifunctionality and sustainability. With respect to GI planning and connectivity assessment, the role of dispersal traits of tree species is gaining increasing attention. However, little evidence is available on how to select plant species to be primarily favored, as well as on the role of landscape heterogeneity and habitat quality in driving the dispersal success. The present work is aimed at suggesting a methodological approach for addressing these knowledge gaps, at fine scales and for peri-urban agricultural landscapes, by means of a case study in the Metropolitan City of Rome. The study area was stratified into Environmental Units, each supporting a unique type of Potential Natural Vegetation (PNV), and a multi-step procedure was designed for setting priorities aimed at enhancing connectivity. First, GI components were defined based on the selection of the target species to be supported, on a fine scale land cover mapping and on the assessment of land cover type naturalness. Second, the study area was characterized by a Morphological Spatial Pattern Analysis (MSPA) and connectivity was assessed by Number of Components (NC) and functional connectivity metrics. Third, conservation and restoration measures have been prioritized and statistically validated. Notwithstanding the recognized limits, the approach proved to be functional in the considered context and at the adopted level of detail. Therefore, it could give useful methodological hints for the requalification of transitional urban–rural areas and for the achievement of related sustainable development goals in metropolitan regions.

The corporate companies dealing with FMCG products have started focusing on rural markets as the urban markets have become saturated and highly competitive. Capturing the rural markets brings forth a whole new set of challenges as it is laborious to break in. This market presents the companies with gamut challenges on a new dimension which demand entirely different strategies as compared to the ones used in urban areas. Studying the rural markets for rural markets has become crucial more than ever. It is an objective learning, psychiatry of dispersion, impact of the FMCG in rural areas. This research uses diverse utensils, procedure toward analyze composed records. Several of the features used in analyzing the data are the consumer characteristics like educational qualifications, professions they are in, and the income levels. The role of TV media advertising is also analyzed. Many deals and promotions advertised on TV are investigated. The scope of authority wield by publicity happening customer choice production has looked into. The different levels of media exposure and preferable TV watching times and their favorite programs considered while analyzing the data. The spending prototype of rural clients on FMCG is examined and further categorized based on their income levels, educational qualifications, and legal awareness of consumer act.

AbstractUrbanization affects near-surface climates by increasing city temperatures relative to rural temperatures [i.e., the urban heat island (UHI) effect]. This effect is usually measured as the relative temperature difference between urban areas and a rural location. Use of this measure is potentially problematic, however, mainly because of unclear “rural” definitions across different cities. An alternative metric is proposed—surface temperature cooling/warming rates—that directly measures how variations in land-use and land cover (LULC) affect temperatures for a specific urban area. In this study, the impact of local-scale (<1 km2), historical LULC change was examined on near-surface nocturnal meteorological station temperatures sited within metropolitan Phoenix, Arizona, for 1) urban versus rural areas, 2) areas that underwent rural-to-urban transition over a 20-yr period, and 3) different seasons. Temperature data were analyzed during ideal synoptic conditions of clear and calm weather that do not inhibit surface cooling and that also qualified with respect to measured near-surface wind impacts. Results indicated that 1) urban areas generally observed lower cooling-rate magnitudes than did rural areas, 2) urbanization significantly reduced cooling rates over time, and 3) mean cooling-rate magnitudes were typically larger in summer than in winter. Significant variations in mean nocturnal urban wind speeds were also observed over time, suggesting a possible UHI-induced circulation system that may have influenced local-scale station cooling rates.

subsistence production (where in the colonial period mainly extra-economic factors such as forced cultivation or forced labour caused the integration of the peasantry in the market exchange). Socialist development was there-fore strongly identified with modernising through the rapid expansion of the state sector, that is, nationalisation and mechanisation on an ever-increasing scale. The peasantry would be gradually absorbed within this expanding sector, and hence, at first, the role of the peasantry was seen as essentially passive with its transformation mainly centring on social aspects. As such, the policy of communal villages became virtually a habitational concept (and was in actual fact the responsibility of the national directorate of housing): a question of social infrastructures (water supplies, schools, etc.) within a concept of communal life without concerning production and its transformation. This view conflicted heavily with the objective conditions in the rural areas characterised by a deep involvement of the peasantry in market relationships and their dependence on it either as suppliers of labour power or as cash crop producers. This contradiction became more obvious, when the balance of payments became a real constraint (in 1979) and, hence, the question of financing accumulation cropped up more strongly in practice. The peasantry as suppliers of cash crops, of food and of labour power to the state sectors occupied a crucial position in production and accumulation. However, the crucial question then becomes whether the peasantry only performs the role of supplying part of the accumulation fund or whether the peasantry itself is part and parcel of the process of transformation and hence that accumulation embraces as an integral part the transformation of peasant agriculture into more socialised forms of production. In other words, it poses the question whether the strategy is based on a primitive socialist accumulation on the basis of the peasantry (transferring the agrarian surplus to the develop-ment of the state sector), or whether accumulation includes the transformation of peasant agriculture. Clearly, the way this question is posed in practice will influence heavily the nature of the organisation of the exchange between the state sector and the peasantry. The proposition that the state sector can develop under its own steam (with or without the aid of external borrowing) cannot bypass this crucial question since, on the one hand, a considerable part of foreign exchange earnings and of the food supply to the towns depended on peasant production and, on the other, the very conditions of productivity and profitability in the agrarian state sector depended heavily on the organic link that existed.between labour supply and family agriculture. The monetary disequilibrium originating from the state sector has a severe impact on the organisation of the exchange between the state sector and the peasantry. First, the imbalance between the demand for and the supply of consumer commodities affected rural areas differently from urban areas. The reason was that in urban areas the rationing system guaranteed to each family a minimum quantity of basic consumer necessities at official prices. In the rural areas the principal form of rationing remained the queue! Hence, forced savings were distributed differently over urban and rural areas. Furthermore, the concentration of resources on the state sector also implied that the peasants'

A mother’s healthy conduct may lead to the healthy conduct of their children. Thus, this study aimed to verify the role of demographic factors in the relationship between mothers’ physical activity (PA) and commuting to work with children and adolescent’s PA and commuting to school. This cross-sectional study comprised 1421 children and adolescents aged 6 to 17 years and 1421 mothers, from Brazil. PA, commuting, socioeconomic status (SES), skin color/ethnicity, and living area were evaluated by questionnaire. Logistic binary regression models were used. Results indicated that mothers’ PA and commuting were associated with children and adolescent’s PA and commuting to school in crude and adjusted models. Considering the role of the demographic factors, an association was only observed for girls in the relationship between mother’s PA with children’s PA. In adolescents, an association was observed in both high/low SES, boys/girls, and rural/urban areas. Regarding children and adolescent active commuting to school, there was an association with mothers commuting. All demographic factors were strongly associated, except for rural areas. Therefore, mothers’ PA as well as commuting to work are associated with children and adolescent’s PA and commuting to school. Sex, living area, and SES are the related demographic factors.

Green infrastructure (GI), as a concept and as a tool for environmental land-use planning at various scales, has burst onto the academic, political, and policy-making scenes in the last two decades. This tool, associated with strategic planning, offers integrated solutions for improving the ecological connectivity and urban resilience of open spaces, especially those affected by processes of urban sprawl, the abandonment of agriculture, and the territorial fragmentation of habitats and traditional agricultural landscapes. In spite of the advantages of GI, its design and implementation face a range of challenges and limitations. In this context, this paper has two objectives: Firstly, to address a critical review of recent literature on the subject, which, among other things, highlights the lack of references to the role of peri-urban agriculture in GI planning, and the positive contribution made by peri-urban agriculture to the local food supply and other regulatory and cultural services. Secondly, to propose a methodology to contribute to integrating practical GI planning in metropolitan regions to maximize the activation of traditional agricultural landscapes and the improvement of landscape connectivity in metropolitan regions for the reconnection of rural-urban relationships.

Anthropogenic land use has led to the loss and fragmentation of native habitats and disruption to ecosystem processes, resulting in a decline in landscape connectivity and biodiversity. Here, in order to find the potentials of improvements in ecological connectivity, we provide a spatial analysis to present differences in ecological connectivity based on land cover maps and urban habitat maps in Suwon city, Republic of Korea. We generated two permeability maps for use in a network analysis, one being land cover and the other urban habitat, including a 5-km buffer area from the city boundary. We then determined the current-flow betweenness centrality (CFBC) for each map. Our results indicate that forests are typically the most highly connected areas in both maps. However, in the land cover map results, nearly all high-priority areas were in the mountainous region (CFBC value: 0.0100 ± 0.0028), but the urban habitat indicated that grasslands and rivers within the city also significantly contribute to connectivity (CFBC value: 0.0071 ± 0.0022). The CFBC maps developed here could be used as a reference when introducing green infrastructure in cities. Before establishing ecological networks for urban areas, future work should integrate the land use and ecological data of different administrative districts with continuous ecological connection.

This paper analyzes the role of natural geography for explaining local population change patterns. Using spatially detailed data for Spain from 1960 to 2011, the estimation results indicated that natural geography variables relate to about half of the population growth variation of rural areas and more than a third of the population growth variation of urban areas during this period. Local differences in climate, topography, and soil and rock formation as well as distance to aquifers and the coast contribute to variations in local population growth patterns. Although, over time, local population change became less related to differences in natural geography, natural geography is still significantly related to nearly a third of the variation in local population change in rural areas and the contribution of temperature range and precipitation seasonality has even increased. For urban areas, weather continues to matter too, with growth being higher in warmer places.

Rural–urban linkages play a fundamental role in the generation of service, development, health treatment and wealth. Yet, for various reasons the importance of such linkages is not recognized and thus unnoticed in rural economic and trade policies. The present paper investigates infrastructure problem, institutional constraints and dependency rural area on near rural service trade barriers that tend to discourage linkages between rural and urban areas and thus prevent a process of rural empowerment and economic development. The findings of our review indicate that clustering rural and urban areas into regional planning units may create the necessary enabling environment for extensive trade networks and knowledge switch over between the city and the neighbor rural-side. As such, stronger rural–urban linkages could also play a crucial role in fulfill rural areas demand in developing countries.

Abstract. The rural–urban interface (RUI), known as the area where structures and other human developments meet or intermingle with wildland and rural area, is at present a central focus of wildfire policy and its mapping is crucial for wildfire management. In the Mediterranean Basin, humans cause the vast majority of fires and fire risk is particularly high in the proximity of infrastructure and of rural/wildland areas. RUI's extension changes under the pressure of environmental and anthropogenic factors, such as urban growth, fragmentation of rural areas, deforestation and, more in general, land use/land cover change (LULCC). As with other Mediterranean countries, Portugal has experienced significant LULCC in the last decades in response to migration, rural abandonment, ageing of population and trends associated with the high socioeconomic development. In the present study, we analyzed the LULCC occurring in this country in the 1990–2012 period with the main objective of investigating how these changes affected RUI's evolution. Moreover, we performed a qualitative and quantitative characterization of burnt areas within the RUI in relation to the observed changes. Obtained results disclose important LULCC and reveal their spatial distribution, which is far from uniform within the territory. A significant increase in artificial surfaces was registered near the main metropolitan communities of the northwest, littoral-central and southern regions, whilst the abandonment of agricultural land near the inland urban areas led to an increase in uncultivated semi-natural and forest areas. Within agricultural areas, heterogeneous patches suffered the greatest changes and were the main contributors to the increase in urban areas; moreover, this land cover class, together with forests, was highly affected by wildfires in terms of burnt area. Finally, from this analysis and during the investigated period, it appears that RUI increased in Portugal by more than two-thirds, while the total burnt area decreased by one-third; nevertheless, burnt area within RUI doubled, which emphasizes the significance of RUI monitoring for land and fire managers.

This article explores two contrasting perspectives on the role of informal settlements in urban labour markets. One proposes that they help to lift households out of rural poverty and onto a path to prosperity through affordable access to urban opportunities. The other suggests that the debilitating conditions confine residents to enduring hardship and insecurity. South Africa is an important test case because of the extent of social and spatial inequalities, and the policy ambivalence towards shack settlements. Preliminary evidence indicates that employment rates are much closer to formal urban areas than to rural areas, but conditions of employment are noticeably worse. Other forms of data are required to assess the magnitude and timescale of economic progression for households.
