Primate crop raiding in Uganda: actual and perceived risks around Budongo Forest Reserve

Crop damage by wildlife is a significant threat to global conservation and human development. This interdisciplinary study compared the actual and perceived risk of primate crop raiding around Budongo Forest Reserve, northwest Uganda during 2004/2005. Weekly farm monitoring established that at least seven wild species damage crops. and primates (primarily baboons) are responsible for forty percent of all raids. The creation of risk maps using GIS technology and logistic regression revealed that those cultivating maize close to the forest edge are particularly vulnerable to loss. An elevated level of human presence was found to significantly reduce raids by wild species although it is not considered effective due to the high social cost. Overall the majority of farmers experience little damage by wildlife and many other factors limit agricultural production e.g. insects, weather and domestic livestock; goats raid more frequently than any other animal and their pruning of maize was proven to significantly reduce yield. Despite the low risk of actual loss, semi-structured interviews, focus groups and participant observation revealed that crop raiding by wild species is believed to be the most significant limitation to livelihoods in this area. Damage intensity, fluctuations in social condition and restrictions on traditional crop protection methods all inflate perceptions of risk. Crop damage by wildlife also symbolizes control by external forces; the forest is believed to be 'owned' by the same organizations that impose conservation legislation and restrict access to resources. Raiding species, and primates in particular, are judged alongside human moral values and local people are more tolerant of animals they believe they can control or that have associated benefits i.e. domestic and game species. This thesis emphasises the need to both reduce damage to acceptable levels and increase tolerance toward wild species at this site. Mitigation strategies are suggested that build upon traditional techniques, provide an economic incentive for conserving wildlife and assist farmers to manage the conflict. Ultimately, however, the success of any initiative will depend on the participation of local people

Wasted Food, Wasted Energy: The Embedded Energy in Food Waste in the United States

This work estimates the energy embedded in wasted food annually in the United States. We calculated the energy intensity of food production from agriculture, transportation, processing, food sales, storage, and preparation for 2007 as 8080 ± 760 trillion BTU. In 1995 approximately 27% of edible food was wasted. Synthesizing these food loss figures with our estimate of energy consumption for different food categories and food production steps, while normalizing for different production volumes, shows that 2030 ± 160 trillion BTU of energy were embedded in wasted food in 2007. The energy embedded in wasted food represents approximately 2% of annual energy consumption in the United States, which is substantial when compared to other energy conservation and production proposals. To improve this analysis, nationwide estimates of food waste and an updated estimate for the energy required to produce food for U.S. consumption would be valuable

Using Participatory Risk Mapping (PRM) to identify and understand people's perceptions of crop loss to animals in uganda

Considering how people perceive risks to their livelihoods from local wildlife is central to (i) understanding the impact of crop damage by animals on local people and (ii) recognising how this influences their interactions with, and attitudes towards, wildlife. Participatory risk mapping (PRM) is a simple, analytical tool that can be used to identify and classify risk within communities. Here we use it to explore local people's perceptions of crop damage by wildlife and the animal species involved. Interviews (n = 93, n = 76) and seven focus groups were conducted in four villages around Budongo Forest Reserve, Uganda during 2004 and 2005. Farms (N = 129) were simultaneously monitored for crop loss. Farmers identified damage by wildlife as the most significant risk to their crops; risk maps highlighted its anomalous status compared to other anticipated challenges to agricultural production. PRM was further used to explore farmers' perceptions of animal species causing crop damage and the results of this analysis compared with measured crop losses. Baboons (Papio anubis) were considered the most problematic species locally but measurements of loss indicate this perceived severity was disproportionately high. In contrast goats (Capra hircus) were considered only a moderate risk, yet risk of damage by this species was significant. Surprisingly, for wild pigs (Potamochoerus sp), perceptions of severity were not as high as damage incurred might have predicted, although perceived incidence was greater than recorded frequency of damage events. PRM can assist researchers and practitioners to identify and explore perceptions of the risk of crop damage by wildlife. As this study highlights, simply quantifying crop loss does not determine issues that are important to local people nor the complex relationships between perceived risk factors. Furthermore, as PRM is easily transferable it may contribute to the identification and development of standardised approaches of mitigation across sites of negative human-wildlife interaction. © 2014 Webber, Hill

Study protocol:the effectiveness and cost effectiveness of a brief behavioural intervention to promote regular self-weighing to prevent weight regain after weight loss: randomised controlled trial (The LIMIT Study)

BACKGROUND: Although obesity causes many adverse health consequences, modest weight loss reduces the incidence. There are effective interventions that help people to lose weight but weight regain is common and long term maintenance remains a critical challenge. As a high proportion of the population of most high and middle income countries are overweight, there are many people who would benefit from weight loss and its maintenance. Therefore, we need to find effective low cost scalable interventions to help people achieve this. One such intervention that has shown promise is regular self-weighing, to check progress against a target, however there is no trial that has tested this using a randomised controlled design (RCT). The aim of this RCT is to evaluate the effectiveness and cost effectiveness of a brief behavioural intervention delivered by non-specialist staff to promote regular self-weighing to prevent weight regain after intentional weight loss. METHODS: A randomised trial of 560 adults who have lost ≥5 % of their initial body weight through a 12 week weight loss programme. The comparator group receive a weight maintenance leaflet, a diagram representing healthy diet composition, and a list of websites for weight control. The intervention group receive the same plus minimally trained telephonists will ask participants to set a weight target and encourage them to weigh themselves daily, and provide support materials such as a weight record card. The primary outcome is the difference between groups in weight change from baseline to 12 months. DISCUSSION: If effective, this study will provide public health agencies with a simple, low cost maintenance intervention that could be implemented immediately.

The ebb and flow of adaptive co-management: a longitudinal evaluation of a conservation conflict

Adaptive co-management (ACM) is an emerging approach to the governance of social-ecological systems, but there are few long-term assessments of its efficacy. This is especially true in conservation conflicts, where ACM can mitigate disputes between polarised stakeholders. We evaluated ACM that emerged in 2005 to address conflict between seal conservation and fisheries interests in the Moray Firth, Scotland. We interviewed 20 stakeholders in 2015, repeating a survey carried out in 2011 which applied an indicator framework to measure outcomes and pre-conditions for ACM to continue. In 2015, all but one of the 12 outcome indicators were positive, the exception being the conservation status of salmon. However, pre-conditions for ACM’s continuation had weakened, with declines between 2005, 2011 and 2015. These were most marked for three indicators: leaders prepared to champion the process, presence of a bridging organisation or individual, and participation of all impacted stakeholders. The results show that ACM in this conservation conflict is dynamic. Perceived declines in salmon abundance and increases in seal numbers have renewed tensions amongst stakeholders, triggering a ‘revival’ phase of ACM initiated by fishery interests. Our study provides empirical evidence of ACM’s fluid nature, and how resource crises can reignite ACM. We suggest that participatory evaluation is a potentially important early-warning mechanism that can identify remedial action and galvanise stakeholders to respond to the re-emergence of conflict

Lemurs in Cacao: Presence and Abundance within the Shade Plantations of Northern Madagascar

© 2019 S. Karger AG, Basel. The recognition that much biodiversity exists outside protected areas is driving research to understand how animals survive in anthropogenic landscapes. In Madagascar, cacao (Theobroma cacao) is grown under a mix of native and exotic shade trees, and this study sought to understand whether lemurs were present in these agroecosystems. Between November 2016 and March 2017, discussions with farmers, nocturnal reconnaissance surveys and camera traps were used to confirm the presence of lemurs in the Cokafa and Mangabe plantations near Ambanja, north-west Madagascar. Four species of lemur were encountered in nocturnal surveys: Mirza zaza, Phaner parienti, Microcebussp. and Cheirogaleussp. with encounter rates of 1.2, 0.4, 0.4 and 0.3 individuals/km, respectively. The presence of Lepilemur dorsalis was confirmed by camera trap. This is the first time lemurs have been studied in cacao plantations, and understanding how these threatened animals use anthropogenic landscapes is vital for their conservation

Protecting great apes from disease: Compliance with measures to reduce anthroponotic disease transmission

Abstract: The emergence of infectious diseases, such as COVID‐19, impacts livelihood strategies and conservation tools reliant on human‐wildlife interactions, such as wildlife‐based tourism and research. This is particularly relevant to great ape conservation, as humans and great apes are susceptible to being infected by similar pathogens. Evidence‐based strategies are required to prevent infectious disease transmission to great apes and people involved in, or living close to, tourism sites. The development of disease‐safe recommendations and their effective operationalisation require an understanding of what affects visitor compliance. Based on an international sample of past (N = 420) and potential future visitors (N = 569) to wild great ape tourism sites in Africa, we used an online questionnaire to characterise visitors' practices, assess expectations (e.g. about proximity to great apes) and identify key factors related to potential compliance with disease mitigation measures. This was implemented adapting a framework from health literature (the Health Belief Model; HBM), particularly focused on reducing COVID‐19 transmission at an early stage of the pandemic. Visitors expressed less willingness to being vaccinated against COVID‐19 (which, at the time our survey was conducted, had only just started being administered to very high‐risk groups), wearing a facemask during trekking (although willing when viewing the apes) and quarantine after international travel before visiting great apes. Region of nationality, expectations about the visitor experience and perceived effectiveness of specific measures were important factors explaining variation in potential compliance across multiple behaviours. By gaining a better understanding of what fosters compliance with disease mitigation measures, we obtained insights that are essential for assessing feasibility, facilitating effective communication, and guiding implementation at great ape tourism sites with importance not only for COVID‐19 but also for other infectious diseases more broadly, particularly at early stages of future pandemics. While requiring adaptive management as situations evolve (e.g. vaccination becoming more widely accessible), these will contribute towards a more sustainable visitor experience that can effectively deliver positive outcomes for people and biodiversity.

Quantity does not always mean quality: the importance of qualitative social science in conservation research

Qualitative methods are important in gaining a deep understanding of complex problems and poorly researched areas. They can be particularly useful to help explain underlying conservation problems, as in Rust et al. (2016). However, the significance in choosing and justifying appropriate methodological frameworks in conservation studies should be given more attention to ensure data are collected and analysed appropriately. We thank Potgieter et al. (2017) for their critical analysis of Rust et al. (2016), but they appear unaware of when, why and how such methods should be used. We clarify the methods described in Rust et al. (2016) and explain sampling strategies in qualitative studies. To improve familiarity with qualitative methods among natural scientists we recommend expanded training in social sciences and collaborating with social scientists. Given the scale of human impacts on the environment, this type of nuanced analytical skill is critical for moving conservation forward

Genetic polymorphisms located in genes related to immune and inflammatory processes are associated with end-stage renal disease: a preliminary study

Background Chronic kidney disease progression has been linked to pro-inflammatory cytokines and markers of inflammation. These markers are also elevated in end-stage renal disease (ESRD), which constitutes a serious public health problem. Objective To investigate whether single nucleotide polymorphisms (SNPs) located in genes related to immune and inflammatory processes, could be associated with ESRD development. Design and methods A retrospective case-control study was carried out on 276 patients with ESRD and 288 control subjects. Forty-eight SNPs were genotyped via SNPlex platform. Logistic regression was used to assess the relationship between each sigle polymorphism and the development of ESRD. Results Four polymorphisms showed association with ESRD: rs1801275 in the interleukin 4 receptor (IL4R) gene (OR: 0.66 (95%CI=0.46-0.95); p=0.025; overdominant model), rs4586 in chemokine (C-C motif) ligand 2 (CCL2) gene (OR: 0.70 (95%CI=0.54-0.90); p=0.005; additive model), rs301640 located in an intergenic binding site for signal transducer and activator of transcription 4 (STAT4) (OR: 1.82 (95%CI=1.17-2.83); p=0.006; additive model) and rs7830 in the nitric oxide synthase 3 (NOS3) gene (OR: 1.31 (95%CI=1.01-1.71); p=0.043; additive model). After adjusting for multiple testing, results lost significance. Conclusion Our preliminary data suggest that four genetic polymorphisms located in genes related to inflammation and immune processes could help to predict the risk of developing ESRD.This work was supported by grants from Instituto de Salud Carlos III (Ref: PI08/0738 and PI11/00245) to SR and Junta de Castilla y Leon (Ref: GRS 234/A/08) to ET.

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy
