RESUMO

This paper examines the impacts of human-wildlife conflict (HWC) in the Kakum Conservation Area (KCA), Ghana. The primary focus is on crop-raiding by elephants. Using ethnographic methodologies, the findings shed light on the broader impacts of HWC in rural communities. These include food insecurity characterized by a notable decline in the quality and quantity of food accessible to individuals and families affected by crop-raiding. The study also underscores the negative impacts on mental and physical wellbeing as residents contend with stress, anxiety and fear due to crop-raiding and encounters with elephants. Furthermore, this research uncovers how coping mechanisms employed by locals in response to these challenges may result in problem drinking. Also, efforts taken to mitigate crop-raiding unintentionally result in health consequences for farmers who face risks of contracting diseases such as malaria and suffer from sleep deprivation due to guarding their fields at night. More importantly, this study provides an in-depth examination of the broader vulnerabilities caused by HWC which are often ignored and underscores the importance of looking beyond the direct impacts in HWC hotspots like KCA.

RESUMO

Scholars and practitioners have been striving to develop straightforward and effective tools to measure protected area management effectiveness (PAME). UNESCO Biosphere Reserves (BR), with their unique functional and zonation schemes are monitored according to their compulsory 10-year Periodic Review (PR), which is useful for UNESCO's evaluation purposes but lacks comprehensiveness and utility for adaptive management. Based on existing PAME methodologies, we develop and propose the first quantitative tool for the evaluation of BR management effectiveness, that would enhance and complement the currently used qualitative PR report, and serve the rapid evaluation needed for BR managers to monitor, evaluate, and adapt their management approach to achieve the three functions of BRs. The tool consists of 65 indicators, embodied within the 6 elements of the World Commission on Protected Areas Framework. We then tested this tool, named Biosphere Reserve Effectiveness of Management index (BREMi) to evaluate management effectiveness across the Arab Man and the Biosphere Reserve network involving 17 BRs spanning 8 countries of the Middle East and North Africa. BREMi scores ranged from 4.43 to 8.65 (on a scale between 0 and 10), with a mean of 6.31 ± 1.040. All indicators were considered valuable measures of progress by our respondents, as well as by independent experts. We discuss our findings in light of available literature concerning the Arab region and through the conceptual frames of adaptive management and resilience. Finally, we discuss where the BREMi tool would be most useful for BR management authorities in the iterative process of evaluation and adaptive management.

RESUMO

The environmental impacts of cannabis cultivation have been an issue of growing concern, with legalization often framed as a means to introduce regulations that hinder damaging practices. However, the concept of frontier expansion presents the possibility that the widespread establishment of this new industry may institute an additional source of habitat encroachment. Here, through geospatial analysis, we employ Colorado as a case study to investigate the distribution of licensed recreational cannabis cultivators, potential habitat infringement of threatened and endangered species, and LULC change. From 2011 to 2016, licensed cannabis cultivation has resulted in over 67 ha of LULC change toward more developed land uses. In addition, nearly 15 km of new fencing was constructed establishing over 38 ha of fenced areas, and nearly 60 ha of vegetation was cleared. Much of this cannabis-driven LULC change is identified within the habitats of threatened and endangered species, as well as areas recognized as containing high biodiversity values with the potential for conservation. Thus, notable cannabis-driven frontier expansion is evident. Cannabis-driven LULC change is found to be primarily produced by outdoor and greenhouse facilities, as well as operations utilizing mixed-cultivation methods in rural areas. Therefore, policy instruments that inter alia encourage indoor cannabis cultivation in urban areas are recommended and discussed.

RESUMO

BACKGROUND: Bear bile is widely believed across much of Asia to have medicinal properties. As a result, great numbers of bears have been poached from the wild and numerous bear farms have been set up to drain the animals' bile on a regular basis. Although most such farms are now illegal, they continue to exist in countries such as Lao PDR. A new bear sanctuary is under construction in Luang Prabang in the northern part of the country with the aim of providing shelter to bears rescued from these farms. Understanding the level and nature of local communities' support for this sanctuary is vital for the long-term success of conservation efforts in the area, including outreach. METHODS: This research, drawing from both ethnozoological and conservation frameworks, comprises a household survey (n = 263) administered in five villages surrounding the sanctuary and in-depth interviews conducted with key community leaders and institutional representatives. The questionnaire assessed local socio-economic status and attitudes towards bears, bear bile use, and bear conservation in general. RESULTS: Respondents have generally positive attitudes towards bears and bear conservation. Age, gender, ethnicity, village, and household size have significant influence on attitudes towards bear bile use, which may also be determined by the expansion of sources for the supply of the traditional medicine market in neighboring China. However, many locals lack knowledge about the current status of wild and captive bears. This may be due to inadequate outreach involving community incentives for positively influencing attitudes. We argue that local communities will need to be integrated into conservation efforts while enhancing knowledge of conservation issues through improved outreach and communication. CONCLUSION: Positive attitudes towards bears appear prevalent in the communities surrounding the new sanctuary. Villagers are familiar with laws regarding wildlife conservation but lack a deeper understanding of the status and plight of wild bears in the country, particularly how bear farming is a threat to the species. Conservation efforts must entail culturally relevant co-educational initiatives to garner further support from local communities.

RESUMO

Driven by the underperformance of many protected areas (PAs), protected area management effectiveness (PAME) evaluations are increasingly being conducted to assess PAs in meeting specified objectives. A number of PAME tools have been developed, many of which are based on the IUCN-WCPA framework constituting six evaluative elements (context, planning, input, process, output, and outcomes). In a quest for a more universal tool and using this framework, Leverington et al. (Environ Manag 46(5):685-698, 2010) developed a common scale and list of 33 headline indicators, purported to be representative across a wide range of management effectiveness evaluation tools. The usefulness of such composite tools and the relative weighting of indicators are still being debated. Here, we utilize these headline indicators as a benchmark to assess PAME in 37 PAs of four types in Krasnoyarsk Kray, Russia, and compare these with global results. Moreover, we review the usefulness of these indicators in the Krasnoyarsk context based on the opinions of local PA management teams. Overall, uncorrected management scores for studied PAs were slightly better (mean = 5.66 ± 0.875) than the global average, with output and outcome elements being strongest, and planning and process scores lower. Score variability is influenced by PA size, location, and type. When scores were corrected based on indicator importance, the mean score significantly increased to 5.75 ± 0.858. We emphasize idiosyncrasies of Russian PA management, including the relative absence of formal management plans and limited efforts toward local community beneficiation, and how such contextual differences may confound PAME scores when indicator weights are treated equal.

RESUMO

Worldwide efforts have concentrated on developing monitoring methods that would enhance the assessment of progress toward achieving the 2010 conservation objectives of the Convention on Biological Diversity. Threat reduction assessment is one such method. It provides an indirect measure of the effects of a conservation project by evaluating changes in human-induced direct threats to protected areas. We applied modified threat reduction assessments and the 2008 International Union for Conservation of Nature standardized lexicon for classification of threats to Horsh Ehden and Al-Shouf Cedar nature reserves in Lebanon. Our goal was in part to test the suitability of this tool for improving monitoring and management effectiveness of protected forests in Lebanon. In Horsh Ehden, composite threats decreased by 24% from 1997 to 2002, and then increased from 2002 to 2009 by 78% in the core area of the reserve and by 118% in the reserve's buffer zone (surrounds core area, conservation and recreational activities allowed). In Al-Shouf Cedar reserve threats decreased by 51% from 2006 to 2009. Management teams from both reserves have integrated the use of this method to prioritize actions for new management plans. We believe that in Lebanon and other countries with limited resources and weak monitoring programs or that are experiencing political instability threat reduction assessments could be used to improve the effectiveness of protected areas management.

RESUMO

The importance of biodiversity as natural capital for economic development and sustaining human welfare is well documented. Nevertheless, resource degradation rates and persistent deterioration of human welfare in developing countries is increasingly worrisome. Developing effective monitoring and evaluation schemes and measuring biodiversity loss continue to pose unique challenges, particularly when there is a paucity of historical data. Threat reduction assessment (TRA) has been proposed as a method to measure conservation success and as a proxy measurement of conservation impact, monitoring threats to resources rather than changes to biological parameters themselves. This tool is considered a quick, practical alternative to more cost- and time-intensive approaches, but has inherent weaknesses. I conducted TRAs to evaluate the effectiveness of Kruger National Park (KNP) and Limpopo Province, South Africa, in mitigating threats to biodiversity from 1994 to 2004 in 4 geographical areas. I calculated TRA index values in these TRAs by using the original scoring developed by Margoluis and Salafsky (2001)and a modified scoring system that assigned negative mitigation values to incorporate new or worsening threats. Threats were standardized to allow comparisons across the sites. Modified TRA index values were significantly lower than values derived from the original scoring exercise. Five of the 11 standardized threats were present in all 4 assessment areas, 2 were restricted to KNP, 2 to Limpopo Province, and 2 only to Malamulele municipality. These results indicate, first, the need to integrate negative mitigation values into TRA scoring. By including negative values, investigators will be afforded a more accurate picture of biodiversity threats and of temporal and spatial trends across sites. Where the original TRA scoring was used to measure conservation success, reevaluation of these cases with the modified scoring is recommended. Second, practitioners must carefully consider the need and consequences of generalizing threats into generic categories for comparative assessments. Finally, continued refinement of the methodology and its extension to facilitate the transfer of successful conservation strategies is needed.
