Beyond conservation: Assessing broader development outcomes of protected areas in Nepal

Protected Areas (PAs) are set aside for biodiversity conservation but at the same time they are recognized for their role in supporting development goals. However, the benefits provided by PAs also come with costs to local people. Integrated Conservation and Development Projects (ICDPs) are a PA management approach that aim to maximize local benefits through enhancing conservation and development outcomes, while also reducing costs. We implemented a household level survey in two PAs in Nepal managed using an ICDP approach to assess local people's perceived benefits and costs and determine if this approach was achieving its intended outcomes. Since both PAs are popular nature-based tourism (NBT) destinations, respondents were asked questions specific to this activity and others more general to the PA. The coded qualitative responses revealed ten categories of benefits and twelve categories of costs. Most respondents perceived extraction benefits from PAs, and when asked to reflect specifically on NBT, they mostly identified economic benefits. Crop and livestock loss was the main perceived costs from PAs, whereas sociocultural costs were the main costs from NBT. Chi square tests showed that proximity to the PA office and residency status had the most significant differences in perceptions of benefits and costs from both PAs and NBT. People perceived very few benefits related to participation, cost mitigation, and conservation, which does not match the intended outcomes of ICDPs. Although there may be practical implications for engaging distant communities in management, this may help to enhance conservation and development outcomes from PAs

Social capital plays a central role in transitions to sportfishing tourism in small-scale fishing communities in Papua New Guinea

Growing concerns about pressures of global change on small-scale fishing communities have resulted in a proliferation of livelihood diversification initiatives linked to tourism. Where the focus is often on the role of financial, physical, and human capital in influencing the uptake of new opportunities, we argue for more consideration of the role of social capital. We implemented 157 household-level surveys in small-scale fishing communities in Papua New Guinea and modelled the influence of social and other capital assets on people’s perceptions of how easy it would be to become involved in sportfishing tourism. Social capital had a stronger influence relative to other forms of capital, with perceptions of reciprocity and satisfaction with leadership being the most influential aspects. Based on these results, we stress the importance of developing strategies aimed at understanding, building, and maintaining social capital and related social dynamics when implementing livelihood diversification initiatives

Limits of tilapia aquaculture for rural livelihoods in the Solomon Islands

Increasing pressure on coastal fisheries poses serious threats to local livelihoods and the food security of Pacific Islanders. In response, governments and development agencies have explored tilapia pond aquaculture as an alternative fish production source. Yet, evidence to date on the impact of tilapia aquaculture on rural livelihoods has been inconclusive. Drawing on the sustainable livelihood framework, we analysed the contribution of Mozambique tilapia (Oreochromis mossambicus) aquaculture to the livelihood assets and outcomes of 40 rural farmers in Solomon Islands. First, results showed that 53% of tilapia farmers were satisfied with tilapia aquaculture’s contribution to their human and social assets, while only 28% and 13% were satisfied with its contribution to their physical and financial assets, respectively. Tilapia aquaculture’s contribution to farmers’ natural assets was also limited. Second, and most importantly, there was an insignificant contribution of tilapia aquaculture to food and income security. Our results demonstrate that tilapia farmers rarely consumed tilapia, with only two of the 40 households having consumed tilapia in the seven days prior the interview. Moreover, only eight tilapia farmers sold their tilapia, which contributed 0.002–0.5% of their total weekly revenue. We argue the limited contribution of tilapia aquaculture to food and income stems from the low productivity of the available tilapia species and the low local demand for tilapia at rural markets. Given the current context of declining coastal fisheries and food insecurity concerns in rural Pacific Islands, it is unlikely that the current form of Mozambique tilapia aquaculture will be able to achieve its objective of addressing food and income security as a complement to coastal fisheries

Recreational boaters support the use of mooring buoys to reduce anchor damage to Posidonia oceanica (L.) Delile meadows

Recreational boating is an important economic activity in the Mediterranean Sea that often leads to disturbance by anchoring of Posidonia oceanica meadows, an endemic seagrass that is a critical component of shallow coastal ecosystems. A selfadministered survey of recreational boaters that anchor in a popular mooring site (Cala Blava) in the coast of Mallorca (Balearic Islands, Western Mediterranean) was carried out during the summer season of 2011 to assess their preferences regarding the number of boats anchoring at the cove and the distance between them, their willingness to pay for the use of mooring buoys and their perception of the negative effects that recreational boating may have on the marine environment. Four hundred and twenty five surveys were obtained over a period of 23 days (11 weekend days, 14 week days) with a response rate of 95 %. The number of boats anchored was higher during weekends (30 ± 13 boats) than during the rest of the week (15 ± 5 boats). Most of the respondents considered that both the number of anchored boats and distance between them were adequate, and they were satisfied with their visit to Cala Blava. Anchor damage was identified as the main impact caused in the marine environment by recreational boating. Support for the use of mooring buoys was high (72 %) and 58 % of boaters were willing to pay a fee for buoy use. The most widely accepted fee was 5 Euros per day of use. These results suggest that the public is well aware of the damage caused by anchoring on P. oceanica meadows and that environmental regulation that would reduce this harm through the use of mooring buoys would have wide support from the main users, who would be even willing to pay for the service. This is a bright prospect for the conservation of this valuable and fragile coastal ecosystem

Perceptions of cyclone preparedness: assessing the role of individual adaptive capacity and social capital in the Wet Tropics, Australia

Given projections of future climate-related disasters, understanding the conditions that facilitate disaster preparedness is critical to achieving sustainable development. Here, we studied communities within the Wet Tropics bioregion, Australia to explore whether people’s perceived preparedness for a future cyclone relates to their: (1) perceived individual adaptive capacity (in terms of flexibility and capacity to plan and learn); and (2) structural and cognitive social capital. We found that people's perceived cyclone preparedness was only related to their perceived individual flexibility in the face of change. Given that people's perceived cyclone preparedness was related to individualistic factors, it is plausible that individualism-collectivism orientations influence people's perceptions at an individual level. These results suggest that in the Wet Tropics region, enhancing people’s psychological flexibility may be an important step when preparing for future cyclones. Our study highlights the need to tailor disaster preparedness initiatives to the region in question, and thus our results may inform disaster risk management and sustainable development policies

Marine Mammal Interactions With Fisheries: Review of Research and Management Trends Across Commercial and Small-Scale Fisheries

Marine mammal interactions with fisheries, such as bycatch and depredation, are a common occurrence across commercial and small-scale fisheries. We conducted a systematic review to assess the management responses to marine mammal interactions with fisheries. We analyzed literature between 1995 and 2021 to measure research trends in studies on direct and indirect interactions for: (i) high and low to middle-income countries, (ii) fishery operations (commercial and small-scale), and (iii) taxonomic groups. Management responses were categorized using the framework described previously in peer-reviewed studies. Marine mammal bycatch remains a major conservation concern, followed by marine mammal depredation of fishing gear. A high proportion of studies concentrated on commercial fisheries in high-income countries, with an increase in small-scale fisheries in low to middle-income countries between 1999 and 2020. The insufficient understanding of the social dimensions of interactions and the inevitable uncertainties concerning animal and human behaviors are major challenges to effective management. Despite the key role of human behavior and socioeconomics, we found only eight articles that incorporate human dimensions in the management context. Integrating social dimensions of marine mammal interactions with fisheries could help in setting pragmatic conservation priorities based on enhanced understanding of critical knowledge gaps. An area-specific adaptive management framework could be an effective tool in reducing the risk to marine mammals from fisheries by coupling technical solutions with socio-economic and political interventions. We conclude that despite the vast body of literature on this subject, a “silver bullet” management solution to marine mammal interactions with fisheries does not yet exist

Exploring motives for participation in a perpetual easement program: Going beyond financial incentives

Private land conservation has become an important element of the global conservation portfolio. Often, landowners are encouraged to participate in private land conservation with financial incentives. However, there is a concern that financial incentives may be limited given the ephemeral nature of funding. Financial incentives also have the potential to crowd-out participation from landowners motivated by altruistic factors rather than financial ones. These concerns underscore the importance of understanding drivers of participation in conservation programs. While there is a plethora of studies examining motivations for participation in term-limited conservation programs, there are far fewer that look at landowners' reasons for participating in perpetual programs. We examined landowners' non-financial motivations for participation in a United States Fish and Wildlife perpetual easement program using several analytical approaches. We first looked at correlations between the likelihood of participation in the easement program and survey respondent's beliefs, values, norms, and perceived behavioral control using a Bayesian regression analysis. Next, using a cluster analysis we segmented our landowner sample into two groups, tested for differences between the group theoretical constructs, and looked for patterns in geographic distributions of the clusters. Our results suggested that individuals who accepted responsibility for habitat protection and recognized habitat threats were more likely to have participated in the easement program. We did not find significant demographic patterns in our cluster analysis but did see differences across the tested theoretical constructs of theory of planned behavior and value-belief norm theory. Further exploration of variation revealed potential for conservation opportunities and allowed us to make recommendations for future policy actions

Socio-economic drivers of adoption of small-scale aquaculutre in Indonesia

Aquaculture has a critical role in achieving the UN’s Sustainable Development Goals of increasing benefits that low-income and least-developed countries derive from marine resources. Its capacity to deliver these outcomes is challenging, particularly for marginalized groups. This is especially true if the introduction of novel technologies is applied with incomplete understanding of socio-economic and bio-physical contexts. We examined what socio-economic factors affect people’s perceptions of adoption of lobster aquaculture in rural households in Indonesia. We used multiple linear regression with model averaging to test the influence of five capital assets (human, social, natural, physical, and financial), including agency, equity, and household sensitivity, on people’s perceived ability to adopt lobster aquaculture. Agency and sensitivity had the greatest influence on the dependent variable. We then used correlation analysis to develop a heuristic model of potential indirect causal mechanisms affecting people’s perceptions of adoption. Our results point to the existence of a ‘sensitivity trap’, where more sensitive or marginalized households are less likely to engage in new economic opportunities. We emphasize the value of multifaceted programs for improving livelihoods, particularly for poorer, more vulnerable households as one way to support the UN’s commitment to using aquaculture as a pathway to achieving sustainable development

Scientific response to a cluster of shark bites

1. Shark bites are of high public concern globally. Information on shark occurrence and behaviour, and of the effects of human behaviours, can help understand the drivers of shark-human interactions. In Australia, a number of shark bite clusters occurred over the last decade. One of these took place in Cid Harbour the Whitsundays, Queensland, a region for which little was known about the shark community. Here, we describe and evaluate the research in response to that shark bite cluster. 2. Fishing methods, acoustic and satellite tracking, and baited remote underwater video cameras (BRUVs) were used to identify the shark species using Cid Harbour, estimate relative abundance, and describe habitat use and residency. Side-scan sonar and BRUVs were also used to assess prey availability. Recreational users were surveyed to understand human behaviour and their awareness and perceptions of ‘Shark Smart’ behaviours. This allowed shark occurrence and behaviour to be interpreted in the context of human behaviours in the Harbour. 3. Eleven shark species were identified. Relative abundance was not unusually high, and residency in Cid Harbour was typically low. For example, 79% of acoustically tagged sharks visited the harbour on <10% days at liberty. Shark prey was available year-round. Notably, anchored boats regularly conduct activities that can attract sharks (dumping food scraps, provisioning and cleaning fish). 4. Alone, the methods used in this study had variable success, but combined they provided a large amount of complementary information. Including a social science component in the research response to the shark bite incidents allowed for a more holistic understanding of the Cid Harbour bite incidents. 5. This study did not identify anything unusual about the shark community that could have contributed to the Cid Harbour shark bite cluster. However, the three incidents involved people bitten almost instantly after entering the water, which is unusual and suggests that feeding/attracting sharks to boats could have been a contributor and also that any species capable of biting humans could have been responsible. 6. The eradication of activities that attract sharks to areas where people enter the water may reduce shark bite risk

Are we killing them with kindness? Evaluation of sustainable marine wildlife tourism

The increasing popularity of marine wildlife tourism (MWT) worldwide calls for assessment of its conservation outcomes and the development of appropriate management frameworks to ensure the conservation of the species and habitats involved as well as the long-term sustainability of this industry. While many studies have examined the positive and/or negative implications of particular forms of MWT, few have attempted to identify factors of concern shared across different types of marine tourism, or examine their implications for sustainability in a broader perspective. We reviewed the existing literature to highlight common impacts on animal behaviour, health and ecology, and to identify successful cases based on minimal negative affects and/or lack of chronic/ irreversible impacts on target species or habitats. To ensure the achievement of both economic and ecologic objectives, the following steps should be integrated in MWT management: 1) Increase of research on the biology and ecology of target species/habitat and application of relevant information for the development of suitable policies, frameworks and management strategies; 2) Structured enforcement of existing policies and enhancement of ecological awareness of visitors through active education; 3) Application of an adaptive management framework to continuously improve the codes of conduct employed; 4) Involvement of different stakeholders and local communities in the development and improvement of the MWT activity. Combining these strategies with the extrapolation of frameworks and policies from cases where adverse ecological impacts have been addressed and successfully resolved can further contribute in ensuring the long-term health and conservation of the species/ habitats involved in MWT activities
