- Description: Local perceptions of environmental and climate change, as well as associated adaptations made by local populations, are fundamental for designing comprehensive and inclusive mitigation and adaptation plans both locally and nationally. In this paper, we analyze people’s perceptions of environmental and climate-related transformations in communities across the Western Solomon Islands through ethnographic and geospatial methods. Specifically, we documented people’s observed changes over the past decades across various environmental domains, and for each change, we asked respondents to identify the causes, timing, and people’s adaptive responses. We also incorporated this information into a geographical information system database to produce broad-scale base maps of local perceptions of environmental change. Results suggest that people detected changes that tended to be acute (e.g., water clarity, logging intensity, and agricultural diseases). We inferred from these results that most local observations of and adaptations to change were related to parts of environment/ecosystem that are most directly or indirectly related to harvesting strategies. On the other hand, people were less aware of slower insidious/chronic changes identified by scientific studies. For the Solomon Islands and similar contexts in the insular tropics, a broader anticipatory adaptation planning strategy to climate change should include a mix of local scientific studies and local observations of ongoing ecological changes.

- Description: In this article, we focus on patriarchy, women, land and livelihoods on A1 farms in Zimbabwe which arose from the fast track land reform programme. There is now significant literature on A1 farms in Zimbabwe. These studies include a number of ethnographic and comparative studies but this literature does not give sustained attention to patriarchy and women. In addition, though, a small number of works have appeared based upon a more focused gender analysis. We draw upon this more focused literature and offer fresh fieldwork evidence based on recent studies undertaken by two of the authors, in Goromonzi and Mazowe districts. At times, radical socio-spatial reorganisation such as fast track may destabilise systems of patriarchy. In the case of fast track, there has been a reconfiguration of relations between men and women yet this is uneven and contradictory and remains within the confines of patriarchal structures, practices and discourses. At the same time, women have manoeuvred and negotiated at local levels to enhance their lives and livelihoods.

- Description: Publisher version , Traditional approaches to monitoring aquatic systems are often limited by the need for data collection which often is time-consuming, expensive and non-continuous. The aim of the study was to map the spatio-temporal chlorophyll-a concentration changes in Malilangwe Reservoir, Zimbabwe as an indicator of phytoplankton biomass and trophic state when the reservoir was full (year 2000) and at its lowest capacity (year 2011), using readily available Landsat multispectral images. Medium-spatial resolution (30 m) Landsat multispectral Thematic Mapper TM 5 and ETM+ images for May to December 1999–2000 and 2010–2011 were used to derive chlorophyll-a concentrations. In situ measured chlorophyll-a and total suspended solids (TSS) concentrations for 2011 were employed to validate the Landsat chlorophyll-a and TSS estimates. The study results indicate that Landsat-derived chlorophyll-a and TSS estimates were comparable with field measurements. There was a considerable wet vs. dry season differences in total chlorophyll-a concentration, Secchi disc depth, TSS and turbidity within the reservoir. Using Permutational multivariate analyses of variance (PERMANOVA) analysis, there were significant differences (p < 0.0001) for chlorophyll-a concentration among sites, months and years whereas TSS was significant during the study months (p < 0.05). A strong positive significant correlation among both predicted TSS vs. chlorophyll-a and measured vs. predicted chlorophyll-a and TSS concentrations as well as an inverse relationship between reservoir chlorophyll-a concentrations and water level were found (p < 0.001 in all cases). In conclusion, total chlorophyll-a concentration in Malilangwe Reservoir was successfully derived from Landsat remote sensing data suggesting that the Landsat sensor is suitable for real-time monitoring over relatively short timescales and for small reservoirs. Satellite data can allow for surveying of chlorophyll-a concentration in aquatic ecosystems, thus, providing invaluable data in data scarce (limited on site ground measurements) environments.

In particular, it discusses challenges relating to teaching a field as contested as African Studies, looking at whether teaching African alternatives to mainstream African politics is helpful and at whether and how one can teach Africa in a way that encourages and develops critical thinking. The article also explores how the racial politics of the context in which one teaches African Studies inevitably affects the way in which students engage with the content of the course. While the article discusses these issues in relation to the South African higher education context in particular, implications for other contexts are also highlighted.

- Description: People who are voluntarily childless, or ‘‘childfree,’’ face considerable stigma. Researchers have begun to explore how these individuals respond to stigma, usually focusing on interpersonal stigma management strategies. We explored participants’ responses to stigma in a way that is cognisant of broader social norms and gender power relations. Using a feminist discursive psychology framework, we analysed women’s and men’s computer-assisted communication about their childfree status. Our analysis draws attention to ‘‘identity work’’ in the context of stigma. We show how the strategic use of ‘‘choice’’ rhetoric allowed participants to avoid stigmatised identities and was used in two contradictory ways. On the one hand, participants drew on a ‘‘childfree-by-choice script,’’ which enabled them to hold a positive identity of themselves as autonomous, rational, and responsible decision makers. On the other hand, they mobilised a ‘‘disavowal of choice script’’ that allowed a person who is unable to choose childlessness (for various reasons) to hold a blameless identity regarding deviation from the norm of parenthood. We demonstrate how choice rhetoric allowed participants to resist stigma and challenge pronatalism to some extent; we discuss the political potential of these scripts for reproductive freedom.

- Description: In this paper I focus on building a conceptual framework for an understanding of the changing dynamics of labour and workers’ sources of power. I begin by identifying worker action that draws on traditional sources of structural and associational power. I then show how the emergence of new forms of labour action is drawing on both old and new sources of power. New global forms of worker power are examined, and I conclude by suggesting that the missing dimension in the three sources of power identified – structural, associational and societal – is institutional power. If these new initiatives are to be sustainable they will need to include one of labour’s traditional sources of power, institutional power. These four-fold sources of power provide the basis for a strategy of union renewal in the age of globalisation.
