Pastures of plenty?: Land rights and community-based agriculture in Peddie,a former homeland town in South Africa

The post-apartheid South African government has emphasized land reallocation in key national policy documents as a means to address apartheid-era legacies of poverty and inequality in the former homelands (black reserves). In this paper, a case study of the Masizame Community Garden Project in Peddie, a small former homeland town, explores the issue of group ownership rights of commonage for poverty alleviation purposes. Poor communication, commitment to gender empowerment and limited transparency of land application processes at different levels of government emerged as key issues that continue to frustrate attempts by local people to secure ownership rights of vacant municipal commonage to earn a livelihood.     

Urban Pulse—The Struggle for Water,Life, and Dignity In South African Cities: The Case of Johannesburg

The struggle for water is a key feature of life in Johannesburg, as it is in all South African cities. This article describes a court action that was brought against the City of Johannesburg by the people of one neighborhood, Phiri, in an effort to secure an adequate supply of water. It is shown how the people of Phiri argued for the removal of discriminatory technology in the form of prepayment meters and for an increase in the quantity of water. Furthermore, it will show how race, class, and geography are articulated in the post-apartheid city.     

Africa’s middle class: building houses and constructing identities in the small town of Buea,Cameroon

Across Africa households are commissioning new domestic buildings for their own use or to rent out rather than waiting for governments to supply urban shelter. We conceptualize this as two interwoven processes: building houses for a new middle class and the building of a new middle class identity. We draw particular attention to the impact of international migration on these processes. The paper uses quantitative data from building permits and qualitative data from 29 interviews and walk-round tours with homeowners and government officials in Buea, Cameroon. Despite some significant caveats (related to housing the urban poor, regulating building standards, and lost local government revenue), we argue that these individually initiated building projects do a reasonable job of meeting local demand for shelter. However, from the perspective of identity-building these buildings are less successful. Whilst homeowners take considerable pride in their building projects, the statements that these structures make about their identities are not always “read” by their neighbours in the way owners hope. New housing is the lens through which Buea’s residents interpret growing levels of inequality and its associated social tensions.     

Directed dispersal of Opuntia species in the Karoo, South Africa: are crows the responsible agents?

The densities of self-established non-indigenous prickly pears (Opuntia ficus-indica) in rangelands of the Karoo recorded on 3434 km of road transects, were on average 800 times greater below telegraph and transmission poles than away from poles, and 200 times greater next to wire fences along roads than in open rangelands. We suggest that this uneven establishment pattern is mainly due to the dispersal of Opuntia ficus-indica seeds by crows and other vertebrates (chiefly primates). Cape (Corvus capensis) and pied crows (C. albus) feed on fruits of Opuntia ficus-indica in the Karoo, and regurgitate pellets containing viable seeds of these plants below nest sites, roosts and occasional perch sites. Crows use man-made structures such as wire fences, telegraph and transmission poles and windmills for perching, roosting and nesting. Crow pellets, containing regurgitated bones and viable seeds of Opuntia spp., and other alien and indigenous plants, are most common around such perch sites. Crows are frequently associated with roads in the Karoo because they scavenge on road kills in the Karoo as well as feeding on fruits, insects and reptiles in road verges. We suggest that dispersal of seeds by crows is important for range extension and establishment of new Opuntia populations.     

Change and continuity of income divide in the American Southeast: A metropolitan scale analyses, 2000–2014

Changing racial/ethnic diversity along with economic growth have also drawn renewed public attention to growing income inequality and lack of economic well-being in the American society. This paper investigates one element of contemporary inequality – the income divide between the richest and the poorest population groups in the metropolises of the U.S. Southeast. This paper examines income divide across southern U.S. metropolises in 2000 and 2014, their change during 2000–2014, their variation across major races/ethnicities, and their relationships with important metropolitan characteristics such as diversity, intermixing, socio-economic status and built-environment attributes. Cartographic, ranking/matrix, and correlations analyses suggest that the largest, most diverse, most segregated, and those with a greater presence of better educated are the most income divided metropolises, whereas the small-to-mid-sized metropolises, with lesser educated population are less divided. The income divide has increased during 2000–2014 in a majority of these metropolises, and for all races/ethnicities, even though Whites and Asians are relatively better-off compared to overall population whereas Blacks and Hispanics lag behind.     

From rags to riches? Migration and intergenerational change in London's housing market, 1971–91

Summary In 1971 under half of London's young people, then living with their parents, lived in households that owned their homes, while well over half lived in rented housing. By 1991, now no longer living with their parents, less than a quarter of these young people were tenants. This paper identifies the components of that intergenerational tenure mobility, distinguishing between home ownership in more, and less, 'desirable' wards, and quantifies the role of migration in mediating the overall changes in Londoner's housing market status between 1971 and 1991. It analyses the moderating factors contributing to housing status mobility, such as labour market mobility and household type, and assesses the differential impact of these processes on men and women. ONS Longitudinal Study data for the period 1971–91 are analysed. Findings are that the aggregate changes concealed a range of housing careers. In particular, in-migrants fared less well in the London housing market than in its labour market.     

Who has long commutes to low-wage jobs? Gender,race, and access to work in the New York region

Geographies of home and work have changed as public investment has favored central and distant suburban locations and as income inequality has increased. These changes result in shifting geographies of advantage that (dis)benefit gender and racial/ethnic groups unevenly. We examine commuting differentials by gender and race/ethnicity based on combinations of wages and commute times using data for the New York region.We find that Black, Asian, and Hispanic women and men are concentrated in jobs that have long commutes and low-wages, and Black and Hispanic workers’ concentrations increased from 2000–2010.Although Asian men and women remain overrepresented in that category, their share decreased in the 2000's.The urban core has become a region of heightened advantage, as White men, and an increasing share of White women, commute short times to well-paid jobs. Disadvantage has expanded for Black and Latina women whose long commutes are not compensated by well-paid employment.     

Competing Place Meanings in Complex Landscapes: A Social–Ecological Approach to Unpacking Community Conservation Outcomes on the Wild Coast,South Africa

Despite a general awareness of the social–ecological complexities within which conservation interventions are embedded, approaches to understanding a diversity of local perspectives of heterogeneous landscapes and how they matter for the outcomes of these interventions are seldom demonstrated. We apply a social–ecological approach to exploring the multiple place meanings related to key landscape elements around a proposed community conservation intervention on the Wild Coast, South Africa, by identifying and analyzing three narratives about this impending change. These narratives mobilize competing meanings of the landscape to argue for or against the conservation project. By linking place meanings to locally defined landscape units (ecotopes), we engage multiple interpretations of the heterogeneous and changing landscape to gain a holistic and more inclusive picture of social–ecological landscape processes such as increasing woodlands and field abandonment. The obstruction of this particular intervention indicates the importance of engaging with multiple cultural values of nature.     

Immigration,Polarization, or Gentrification? Accounting for Changing House Prices and Dwelling Values in Gateway Cities

Past research has identified immigration, social polarization, and gentrification as factors with significant impacts upon price movements and other housing characteristics in gateway cities. This study attempts to compare the effects of these three factors in Toronto and Vancouver, Canada's primary gateway cities, over the period from 1971 to 1996. The paper describes house price changes from Multiple Listing Service rolls and changes of dwelling values in census tracts, and interprets visual evidence for the effects of the three factors. The observed centralization of price gains is then sharpened in a univariate and multivariate analysis of changes in dwelling values for census tracts in each metropolitan area. While there is consistency in the spatial patterns of changes in housing prices and dwelling values between the two cities, there are differences in the importance of the three processes at different times and places. Moreover, strong effects at the metropolitan scale become much more blurred with spatial disaggregation.     

Are There Differences in the Response of Natural Stand and Plantation Biomass to Changes in Temperature and Precipitation? A Case for Two-needled Pines in Eurasia

A comparative discussion of the advantages and disadvantages of natural stands and plantations, including in terms of their productivity and stability, began from the moment of the first forest plantings and continues to this day. In the context of the progressive replacement of natural forests by plantations due to deforestation, the question of how will change the carbon storage capacity of forest cover when replacing natural forests with artificial ones in a changing climate becomes extremely relevant. This article presents the first attempt to answer this question at the transcontinental level on a special case for two-needled pine trees (subgenus Pinus L.). The research was carried out using the database compiled by the authors on the single-tree biomass structure of forest-forming species of Eurasia, in particular, data of 1880 and 1967 of natural and plantation trees, respectively. Multi-factor regression models are calculated after combining the matrix of initial data on the structure of tree biomass with the mean January temperature and mean annual precipitation, and their adequacy indices allow us to consider them reproducible. It is found that the aboveground and stem biomass of equal-sized and equal-aged natural and plantation trees increases as the January temperature and precipitation rise. This pattern is only partially valid for the branches biomass, and it has a specific character for the foliage one. The biomass of all components of plantation trees is higher than that of natural trees, but the percent of this excess varies among different components and depends on the level of January temperatures, but does not depend at all on the level of annual precipitation. A number of uncertainties that arose during the modeling process, as well as the preliminary nature of the obtained regularities, are noted.     

Improving understanding of the spatial dimensions of biophysical change in atoll island countries and implications for island communities: A Marshall Islands’ case study

Using coarse-scale approaches, existing national assessments of vulnerability and adaptation highlight physical land instability as a major threat to atoll island nationhood. However, such evaluations are bereft of detailed, ground-truthed analyses of the physical impacts of climatic change on reef islands, treating islands as homogenous in both biophysical and social characteristics. The distinct geomorphic context of two proximate reef islands (Jeh and Jabat) in the Marshall Islands was examined through conventional land survey techniques. A template documenting the nuances in island topography was used to evaluate simple inundation scenarios, reflecting current and future sea-level changes under storm surge conditions. The variations in local scale community exposure to inundation were discernible. The study highlights the importance of treating coarse-scale assessments with caution and underscores the need for continued commitment to resolving variations in community experiences to environmental change. Notions of risk and exposure are complex and embedded in both the biophysical and social contexts of each island community. Despite a number of targeted urban vulnerability studies in the Pacific there remains a need for efforts to document localised differences in experience to better inform contemporary adaptation efforts.     

Are teachers and students ready for the new middle school geography syllabus in Sweden? Traditions in geography teaching,current teacher practices,and student achievement

The article examines the relationship between selective traditions in geographical education, what middle school teachers choose to emphasise in geographical education, and student achievement. The study, conducted in Sweden, is based on observations made by students in teacher training programmes, interviews with teachers, and analyses of a test administered to middle school students. It shows that selective traditions in geographical education are strong, resulting in a focus on country-related knowledge and map-reading skills. Both teachers and students seem unclear about what other subject-specific skills geography teaching provides. Furthermore, students have difficulty achieving a high level of geographic reasoning. The authors argue that a subject-specific language in geography is important in both teaching and assessment. They stress that students need more practice in geographic reasoning, since this is required by the new curriculum and in the national test in geography for Year 6 (i.e. pupils in the age range 12–13 years). The study adds to earlier research by highlighting Swedish middle school teaching, which is a neglected field within curriculum studies, and by using a combination of methods to analyse the impact of selective traditions.     

Are fossil assemblages in a single sediment core from a small lake representative of total deposition of mite, chironomid, and plant macrofossil remains?

How representative of the whole-lake fossil assemblage are analyses from a single sediment core taken in the centre of a small lake? This question was addressed in five shallow Norwegian lakes that ranged in location from low-altitude, boreal-deciduous forest to mid-alpine environments. Surface-sediment samples were taken from the deepest part of each lake and in two transects running from the lake centre to shore, and analysed for mites, chironomids, and plant remains. Ordination techniques summarised patterns of variation between and within lakes. Correlations between whole-lake assemblages and water depth and sediment organic content (loss-on-ignition) were investigated. Representativeness of each sample of the whole-lake assemblage was determined by comparing Principal Components Analysis scores of the original data with those of Monte Carlo-simulated data sets, using the actual data as constraints in the simulations. The majority of samples are representative of the whole-lake assemblages. Littoral samples, however, are most frequently unrepresentative or poorly representative samples. Water depth is an important controlling variable. A sediment core from the lake centre has the highest probability of representing the whole-lake assemblage. It may, however, also yield the lowest concentrations of terrestrial remains. A sediment core from the slope is slightly more likely to be unrepresentative of the total plant macrofossil assemblage, but generally has higher concentrations of terrestrial remains. These site differences should be considered when choosing a core location. Overall, the three fossil types are deposited in similar patterns. Therefore they can be satisfactorily analysed using a single core.     

What are the transitions of woodlands at the landscape level? Change trajectories of forest,non-forest and reclamation woody vegetation elements in a mining landscape in North-western Czech Republic

This study answers the following research questions: 1) What are the change trajectories of woody vegetation elements at the landscape level? 2) What are the differences in change trajectories amongst the various categories of forest, non-forest and reclamation woody vegetation? 3) How do the change trajectories differ in mining and non-mining landscapes? The study area, measuring 209.6 km², is located in the north-western part of the Czech Republic and may be broken down into 76.8 km² of mining landscape and 132.8 km² of non-mining landscape. Brown coal mining began in this region during the second half of the 18th century and led to the radical transformation of the landscape, including woodlands, during the second half of the 20th century. The source data for this study was obtained from the original stable cadastre maps (1842) and the landscape field mapping performed in 2010. The various woody vegetation elements (forest, non-forest, and reclamation woody plants) and land use/cover (LULC) categories were identified. The GIS symmetrical difference tool was subsequently used to perform an overlay analysis for the individual woody vegetation elements in order to study the change trajectories and to obtain information about the woodlands that have remained unchanged (continuous), the ones that have disappeared (extinct), and the ones that have newly appeared in the landscape (recent). In the case of the non-mining landscape, the total proportion of woodlands has increased (from 17 to 32%), but there has been a decline in the overall volume of forest woody plants found in these areas (from 93 to 74%). As far as the mining landscape is concerned, there has also been an increase in the area covered by woodlands (from 10 to 20%), however, the proportion of forest woody plants has decreased to a much greater extent (from 90 to 31%). From the perspective of extinct woody vegetation, 23.3% of all types of woodlands in the mining landscape may be classified as such, as compared to 10.8% in the non-mining landscape. The primary causes of this decline are mining activities and newly built-up areas. More continuous woody vegetation may be found in the non-mining landscape (42.1%) as compared to the mining landscape (15.4%). Recent woody vegetation, which has primarily replaced grasslands and partially arable land, prevails in both the mining (61.3%) as well as the non-mining (47.1%) landscapes. Different categories of woodlands (forest, non-forest, and reclamation woody vegetation elements) exhibit various change dynamics due to their different structure and the functions they serve. At the most basic level, there has been an overall increase in the occurrence of woodlands in the studied areas. However, once GIS spatial analysis is applied it is possible to see more complex processes in the development of woodland areas as characterised by gains and losses, and it is possible to identify mining and agricultural extensification as the two most significant factors behind the historical changes. Mining leads to a direct decrease in the area of woodlands; conversely, the spontaneous succession of vegetation resulting from agricultural extensification and forest reclamation facilitates woodland recovery. Forest reclamation and reforestation are essential on order to ensure the time continuity of woodlands in both types of landscape, i.e. mining and non-mining. The study presented in this paper proves that it is relevant to analyse the changes occurring in different woodland categories separately. The same methodology may be applied when studying the change dynamics of other important landscape elements, such as wood pastures and wetlands.     

Elemental (C,N, H and P) and stable isotope (δ<Superscript>15</Superscript>N and δ<Superscript>13</Superscript>C) signatures in sediments from Zeekoevlei,South Africa: a record of human intervention in the lake

We used elemental carbon, nitrogen, phosphorus and hydrogen ratios (C/N, N/P and H/C) with total organic carbon (TOC) and total phosphorus (TP) as well as stable carbon and nitrogen isotopes (δ¹³C and δ¹⁵N) to investigate the source and depositional conditions of organic matter in sediments from Zeekoevlei, the largest freshwater lake in South Africa. Typical C/N (10–12), H/C ratios (≥1.7) and δ¹³C_organic values (−22 to −19‰) together with the increase in TOC concentration indicate elevated primary productivity in lower middle (18–22 cm) and top (0–8 cm) sections of the sediment cores. Seepage of nutrients from a nearby waste water treatment plant, rapid urbanization and heavily fertilized farming in the catchments are responsible for the increased productivity. Consistent with this, measured δ¹⁵N_organic values (∼11‰) indicate increased raw sewage input towards the top-section of the core. Although cyanobacterial blooms are evident from the low δ¹⁵N values (∼3‰) in mid-section of the core, they did not outnumber the phytoplankton population. Low N/P ratio (∼0) and high TP (100–2,200 mg l⁻¹) support cyanobacterial growth under N limited condition, and insignificant input of macrophytes towards the organic matter pool. Dredging in 1983, caused sub-aerial exposure of the suspended and surface sediments, and affected organic matter preservation in the upper mid-section (12–14 cm) of the core.     

A Review of “Villages,Women and the Success of Dairy Cooperatives in India: Making Place for Rural Development”

Conceptual advances for understanding the organization of family farms have not yet initiated parallel debates about how they might be aligned with the methods used to understand them. Customization of a novel research approach—farm life history—for an investigation of the socioeconomic organization of forty Australian farms responds to this literature gap. Individual farm life histories were initiated using farm tours (truck journeys) in which changes to the composition of land parcels prompted research conversations. The researcher and participants benefited from using motorized transport and traveling while talking, but the benefits were experienced unevenly across research encounters.     

Research Note—A New Method for Mapping Population and Understanding the Spatial Dynamics of Disease in Urban Areas: Asthma in the Bronx,New York

Determining an accurate depiction of population distribution for urban areas in order to develop an improved "denominator" is important for the calculation of higher-precision rates in GIS analyses, particularly when exploring the spatial dynamics of disease. Rather than using data aggregated by arbitrary administrative boundaries such as census tracts, we developed the Cadastral-Based Expert Dasymetric System (CEDS), an interpolation method using ancillary information to delineate areas of homogeneous values. This method uses cadastral data, land-use filters, modeling by expert system routines, and validation against various census enumeration units and other data. The CEDS method is presented through a case study of asthma hospitalizations in the borough of the Bronx in New York City, in relation to proximity buffers constructed around major sources of air pollution. The analysis using CEDS shows that asthma hospitalization risk due to proximity to pollution sources is greater than previously calculated using traditional disaggregation methods.
