Links between climate change mitigation, adaptation and development in land policy and ecosystem restoration projects: lessons from South Africa
Links between climate change adaptation, mitigation and development co-benefits in land policy and ecosystem restoration projects are hampered by limited understanding of how multi-faceted policy, institutions and projects interact. This paper explores perceptions of co-benefits produced by two community-level projects that pursue ecosystem restoration in South Africa. It develops a new analytical framework to assess the enabling and constraining factors in delivering triple wins for adaptation, mitigation and development. The aim is to investigate the potential for integrating community perspectives into policy and project development and implementation. Data collected through mixed-methods (policy analysis, semi-structured interviews, participatory site visits and focus groups) are analysed using thematic analysis. We find that while the projects investigated have potential to deliver triple wins, siloed approaches presently hinder effective implementation. In particular, project focus on job creation hampers the achievement of longer-term mitigation and adaptation benefits. Operational flexibility, long-term goals, multi-sectoral cooperation and enabling frameworks are imperative to the achievement of triple wins. Findings provide valuable lessons that can be applied across sub-Saharan Africa towards achieving triple wins in climate and development policy and practice, especially those developed with job creation and ecological restoration aims
Unpacking Brazil’s leadership in the global biofuels arena: Brazilian ethanol diplomacy in Africa
Biofuels represent an opportunity for Brazil to exert global leadership by substantially scaling up the production, consumption, and international trade of bioethanol. Africa represents an ideal venue in which to do this, given its suitable agro-climatic conditions and extensive land area. Brazil has consequently sought to establish bilateral partnerships with African countries, as well as North-South-South trilateral partnerships involving the EU and US. However, empirically grounded assessments of how Brazil’s leadership aspirations have unfolded in practice through these partnerships are limited. In this article, we examine Brazil’s potential to exert global political leadership, by analyzing its policy-based, structural, and instrumental qualities in making bilateral and trilateral inroads regarding bioethanol production in Africa. Interviews in Brazil, Africa, and Europe suggest that both the bilateral and trilateral avenues have produced meager results. Lack of domestic strategy and vision, economic recession, and a fragmented alliance network have reduced Brazil’s capacity to achieve its ethanol diplomacy objectives
Delivering Climate-Development Co-Benefits through Multi-Stakeholder Forestry Projects in Madagascar: Opportunities and Challenges
This paper explores multi-stakeholder perspectives on the extent to which forestry projects that pursue ecological restoration and rehabilitation in Madagascar engage with local communities and can co-deliver climate-development benefits. Drawing on mixed methods (policy analysis, semi-structured interviews, participatory site visits and focus groups) in two different forestry contexts, we show that by strengthening access to capital availability, projects can enhance local adaptive capacity and mitigation and deliver local development. We show that active consideration of ecological conservation and action plans early in project design and implementation can co-develop and support monitoring and reporting systems, needed to progress towards integrated climate-compatible development approaches. Climate mitigation benefits remain poorly quantified due to limited interest in, and low capacity to generate, carbon revenues. Monitoring alone does not ensure carbon benefits will materialize, and this research stresses that institutional considerations and strengthened engagement and cooperation between practitioners and communities are key in achieving both climate mitigation and community development impacts. Multiple benefits can be fostered by aligning objectives of multiple landscape actors (i.e., community needs and project developers) and by systematically linking project deliverables, outputs, outcomes and impacts over time, grounded in a theory of change focused on ensuring community buy-in and planning for delivery of tangible benefits

Azathioprine Biotransformation in Young Patients with Inflammatory Bowel Disease: Contribution of Glutathione-S Transferase M1 and A1 Variants
The contribution of candidate genetic variants involved in azathioprine biotransformation on azathioprine efficacy and pharmacokinetics in 111 young patients with inflammatory bowel disease was evaluated. Azathioprine doses, metabolites thioguanine-nucleotides (TGN) and methylmercaptopurine-nucleotides (MMPN) and clinical effects were assessed after at least 3 months of therapy. Clinical efficacy was defined as disease activity score below 10. Candidate genetic variants (TPMT rs1142345, rs1800460, rs1800462, GSTA1 rs3957357, GSTM1, and GSTT1 deletion) were determined by polymerase chain reaction (PCR) assays and pyrosequencing. Statistical analysis was performed using linear mixed effects models for the association between the candidate variants and the pharmacological variables (azathioprine doses and metabolites). Azathioprine metabolites were measured in 257 samples (median 2 per patient, inter-quartile range IQR 1-3). Clinical efficacy at the first evaluation available resulted better in ulcerative colitis than in Crohn's disease patients (88.0% versus 52.5% responders, p = 0.0003, linear mixed effect model, LME). TGN concentration and the ratio TGN/dose at the first evaluation were significantly higher in responder. TPMT rs1142345 variant (4.8% of patients) was associated with increased TGN (LME p = 0.0042), TGN/dose ratio (LME p < 0.0001), decreased azathioprine dose (LME p = 0.0087), and MMPN (LME p = 0.0011). GSTM1 deletion (58.1% of patients) was associated with a 18.5% decrease in TGN/dose ratio and 30% decrease in clinical efficacy. GSTA1 variant (12.8% of patients) showed a trend (p = 0.049, LME) for an association with decreased clinical efficacy; however, no significant effect on azathioprine pharmacokinetics could be detected. In conclusion, GSTs variants are associated with azathioprine efficacy and pharmacokinetics
Collaboration and Multi-Stakeholder Engagement in Landscape Governance and Management in Africa: Lessons from Practice
The severity of interconnected socio-economic and environmental impacts on landscapes and people across Africa are exacerbated as a result of land degradation, conflict, poor governance, competition for land and inequality, and exacerbated by climate change. In pursuing pathways towards a more resilient future, collaborative and multi-stakeholder governance and management of landscapes have been promoted by government agencies, NGOs and conservation organisations as a possible solution. However, there is no single way to achieve effective collaboration, and different landscape projects have experimented with different entry points and engagement processes. Grounded in partnerships amongst researchers, practitioners and development partners with expertise in landscape governance and management in Africa, this book describes and collates key lessons from practice for supporting more resilient and equitable landscapes
Land use, rangeland degradation and ecological changes in the southern Kalahari, Botswana
Dual-scale analyses assessing farm-scale patterns of ecological change and landscape-scale patterns of change in vegetation cover and animal distribution are presented from ecological transect studies away from waterpoints, regional remotely sensed analysis of vegetation cover and animal numbers across the southern Kalahari, Botswana. Bush encroachment is prevalent in semi-arid sites where Acacia mellifera Benth. is widespread in communal areas and private ranches, showing that land tenure changes over the last 40 years have not avoided rangeland degradation. Herbaceous cover is dominated in intensively grazed areas by the annual grass Schmidtia kalahariensis Stent and in moderately grazed areas by the perennial grass Eragrostis lehmanniana Nees. Nutritious perennial grass species including Eragrostis pallens Hack. Ex Schinz remain prevalent in Wildlife Management Areas. Other ecological changes include the invasion of the exotic Prosopis glandulosa Torr. and dense stands of Rhigozum trichotomum Kuntze. in the arid southwest. Regional patterns of wildlife species show that the expansion of cattleposts and fenced ranches has led to large areas of low wildlife conservation value even in areas where cattle production is not practiced. Findings show the need for integrated landscape-scale planning of land use if the ecological value and biodiversity of the southern Kalahari is to be retained
Multi-Criteria Decision Analysis to identify dryland ecosystem service trade-offs under different rangeland land uses
Land degradation undermines ecosystem service provision, limiting economic returns from semi-arid rangelands. We apply a Multi-Criteria Decision Analysis (MCDA) to assess the value of ecosystem services, using monetary and non-monetary techniques in semi-arid rangelands in Kgalagadi District, southern Botswana. In doing so, we provide an empirical understanding of the linkages between policy, land use and the provision of ecosystem services based on the perspectives of local stakeholders identified through interviews and a workshop consultation. Findings suggest communal grazing provides the widest range of monetary and non-monetary values linked to ecosystem service delivery. Current economic incentives and policy initiatives supporting the livestock sector, linked to fencing and borehole drilling, create perverse incentives that over-emphasise commercial food production at the expense of other services. We identify a need for policy reforms to support livelihood diversification through the provision of a wider range of ecosystem services, and for further research to explore market opportunities for veld products and carbon trading. We show that MCDA offers a useful holistic assessment framework that could be applied more widely to semi-arid rangelands globally
