Law in social work education: reviewing the evidence on teaching, learning and assessment

This paper presents the findings from a systemic review of knowledge relating to current practice in the teaching, learning and assessment of law in social work education. The research comprised an internationally conducted systematic review of the literature, together with a survey of current education practice in the four countries of the UK. Two consultation events sought the views of a range of stakeholders, including the perspectives of service users and carers. Set in the context of debates about the relationship between law and social work practice, this paper identifies the common themes emerging from the review and offers an analysis of key findings, together with priorities for future directions in education practice

Interactions between canopy structure and herbaceous biomass along environmental gradients in moist forest and dry miombo woodland of Tanzania

We have limited understanding of how tropical canopy foliage varies along environmental gradients, and how this may in turn affect forest processes and functions. Here, we analyse the relationships between canopy leaf area index (LAI) and above ground herbaceous biomass (AGBH) along environmental gradients in a moist forest and miombo woodland in Tanzania. We recorded canopy structure and herbaceous biomass in 100 permanent vegetation plots (20 m × 40 m), stratified by elevation. We quantified tree species richness, evenness, Shannon diversity and predominant height as measures of structural variability, and disturbance (tree stumps), soil nutrients and elevation as indicators of environmental variability. Moist forest and miombo woodland differed substantially with respect to nearly all variables tested. Both structural and environmental variables were found to affect LAI and AGBH, the latter being additionally dependent on LAI in moist forest but not in miombo, where other factors are limiting. Combining structural and environmental predictors yielded the most powerful models. In moist forest, they explained 76% and 25% of deviance in LAI and AGBH, respectively. In miombo woodland, they explained 82% and 45% of deviance in LAI and AGBH. In moist forest, LAI increased non-linearly with predominant height and linearly with tree richness, and decreased with soil nitrogen except under high disturbance. Miombo woodland LAI increased linearly with stem density, soil phosphorous and nitrogen, and decreased linearly with tree species evenness. AGBH in moist forest decreased with LAI at lower elevations whilst increasing slightly at higher elevations. AGBH in miombo woodland increased linearly with soil nitrogen and soil pH. Overall, moist forest plots had denser canopies and lower AGBH compared with miombo plots. Further field studies are encouraged, to disentangle the direct influence of LAI on AGBH from complex interrelationships between stand structure, environmental gradients and disturbance in African forests and woodlands

Long-Term Vegetation Change in Central Africa: The Need for an Integrated Management Framework for Forests and Savannas

peer reviewedTropical forests and savannas are the main biomes in sub-Saharan Africa, covering most of the continent. Collectively they offer important habitat for biodiversity and provide multiple ecosystem services. Considering their global importance and the multiple sustainability challenges they face in the era of the Anthropocene, this chapter undertakes a comprehensive analysis of the past, present, and future vegetation patterns in central African forests and savannas. Past changes in climate, vegetation, land use, and human activity have affected the distribution of forests and savannas across central Africa. Currently, forests form a continuous block across the wet and moist areas of central Africa, and are characterized by high tree cover (>90% tree cover). Savannas and woodlands have lower tree cover (<40% tree cover), are found in drier sites in the north and south of the region, and are maintained by frequent fires. Recent tree cover loss (2000–2015) has been more important for forests than for savannas, which, however, reportedly experienced woody encroachment. Future cropland expansion is expected to have a strong impact on savannas, while the extent of climatic impacts depends on the actual scenario. We finally identify some of the policy implications for restoring ecosystems, expanding protected areas, and designing sustainable ecosystem management approaches in the region

Social and economical aspects of Miombo woodland management in Southern Africa: options and opportunities for research

Five themes are identified for social, economic and policy research relating to miombo woodland management in southern Africa. They are: (1) patterns of local institutional change; (2) household use of woodland products; (3) markets for woodland products; (4) longer term dimensions to woodland use and exploitation and (5) policy and legislation. These themes are by no means definitive or exhaustive, but are described here as a means of focusing on the scope of future research, and as a basis for identifying priorities

Managing the Miombo woodlands of Southern Africa: policies, incentives and options for the rural poor

Miombo woodlands cover vast areas of southern Africa. Of comparatively little interest for export-oriented commercial logging, they are part of a complex system of rural land use that integrates woodland management with crops and livestock. There is also evidence that woodland resources are extensively used for household consumption, greatly reducing the risk of households falling deeper into poverty as a result of environmental or economic stress. New opportunities for improving the management of miombo woodlands, with poverty mitigation in mind, suggest four policy options. First, communities are becoming more active in managing local natural resources, a result of decentralization and land reforms, which suggests that there may be good scope for strengthening related policy and legal frameworks and the measures to implement them. Second, new and integrated conservation-development approaches are emerging, which suggests possible scope for providing payments for environmental services to increase the value of managed woodlands. Third, markets throughout the region are developing and expanding, which suggests great scope for enhancing forest- based markets by removing restrictive legislation and by supporting local producers and forest enterprises. Fourth, all these opportunities suggest that public forest institutions can be revitalized by strengthening their service delivery orientations, with poverty mitigation as a main objective
