Chilli-briquettes modify the temporal behaviour of elephants, but not their numbers

Crop loss to foraging elephants is one of the most significant causes of conflict between people and elephants in areas where wild elephants share resources with people. Effective solutions to reduce the effects of human-elephant conflict on local livelihoods are thus essential to foster coexistence between elephants and people. We assessed the effectiveness of chilli-briquettes (bricks made of dry chilli, elephant dung and water) in altering elephants use of space in the eastern Okavango Panhandle, Botswana. We burned > 600 briquettes during the night over a 2-month period to test five treatments: frequent burning of (1) chilli and (2) chilli-free briquettes, occasional burning of (3) chilli and (4) chilli-free briquettes, and (5) a control treatment. Using camera traps and footprint surveys we assessed the number of elephants that used experimental sites, and the times at which they did so. We found elephants changed their movement behaviour from predominantly nocturnal to diurnal in areas where chilli-briquettes were burned throughout the night; however, there was no difference in the mean numbers of individuals between treatments with and without chillies. In other words, chilli-briquettes had a repellent but not a deterrent effect on elephants, keeping them away only at times when chilli-briquettes were smouldering. Based on these findings we recommend the use of chilli-briquettes as a method to deter elephants in the short term. In the long term, chilli-briquettes should be applied in combination with other larger-scale mitigation approaches, such as land management and cooperative community-based tools

Determining baselines for human-elephant conflict: A matter of time

Elephant crop raiding is one of the most relevant forms of human-elephant conflict (HEC) in Africa. Northern Botswana holds the largest population of African elephants in the world, and in the eastern Okavango Panhandle, 16,000 people share and compete for resources with more than 11,000 elephants. Hence, it is not surprising this area represents a HEC ‘hotspot’ in the region. Crop-raiding impacts lead to negative perceptions of elephants by local communities, which can strongly undermine conservation efforts. Therefore, assessing trends in conflict levels is essential to developing successful management strategies. In this context, we investigated the trend in the number of reported raiding incidents as one of the indicators of the level of HEC, and assessed its relationship to trends in human and elephant population size, as well as land-use in the study area. For each of these factors, we considered data spanning historical (since the 1970s) and contemporary (2008–2015) time frames, with the aim of comparing subsequent inferences on the drivers of crop raiding and predictions for the future. We find that the level of reported crop raiding by elephants in the eastern Panhandle appears to have decreased since 2008, which seems to be related to the reduction in agricultural land allocated to people in recent years, more than with human and elephant population size. We show that inferences regarding the drivers of HEC and predictions for the future are dependent on the time span of the data used. Although our study represents a first step in developing a HEC baseline in the eastern Panhandle, it highlights the need for additional multi-scale analyses that consider progress in conservation conflict to better understand and predict drivers of HEC in the region

Human-Elephant Conflict and Coexistence in Botswana

In an area of Botswana known as the eastern Okavango Panhandle, roughly 15,000 elephants compete with 15,000 people for access to water, food, and land. The elephants are not confined to any park, reserve, or nation. They roam freely, often in places where people are planting fields, herding livestock, and walking their children home from school

Temporal Partitioning and Overlapping Use of a Shared Natural Resource by People and Elephants

In social-ecological systems around the world, human-wildlife interactions are on the rise, often with negative consequences. This problem is particularly salient in areas where populations of humans and wildlife are increasing and share limited space and resources. However, few studies look at how both people and wildlife navigate shared spaces. To better examine people and wildlife within the same environment, we used methods from social science and spatial ecology to investigate how humans and elephants in Botswana utilize trees, a shared natural resource. Trees provide an opportunity to study shared resource use because they are important for people as firewood and for elephants as food and habitat. We compared tree species gathered on 49 firewood collections with the species damaged by elephants in 83 vegetation plots. We found that many tree species were damaged by elephants in ways that would generate firewood. There was also a strong overlap in the tree species that people collected and the species that elephants browsed and/or damaged. We compared spatially-explicit firewood collection locations and movement data from elephant GPS collars to model resource selection by people and elephants. Proximity to settlements was a strong driving factor for people in firewood collection, while various factors including vegetation characteristics played a role in predicting elephant movement. We found that areas where people collect firewood were negatively correlated with daytime elephant movement and positively correlated with nighttime elephant movement. We further compared the times that people collected firewood with the times when elephants were near the villages and found that people collected firewood during daylight hours when elephants were not nearby, providing further evidence of temporal partitioning. People and elephants utilized the same species of trees, and also had correlated spatial patterns of resource selection. Therefore, elephant foraging of trees provides a previously unrecognized utility to people in the form of firewood creation, and temporal partitioning allows this to occur without direct human-elephant interaction

Integrating social science into conservation planning

A growing body of literature has highlighted the value of social science for conservation, yet the diverse approaches of the social sciences are still inconsistently incorporated in conservation initiatives. Building greater capacity for social science integration in conservation requires frameworks and case studies that provide concrete guidance and specific examples. To address this need, we have developed a framework aimed at expanding the role for social science in formal conservation planning processes. Our framework illustrates multiple ways in which social science research can contribute to four stages of such processes: 1) defining the problem and project team; 2) defining goals; 3) identifying impact pathways and designing interventions; and 4) developing and evaluating indicators of success (or failure). We then present a timely case study of wolf reintroduction in Colorado, U.S.A., to demonstrate the opportunities, challenges, and complexities of applying our framework in practice

Good Practices in the Co-Production of Knowledge: Working Well Together in Environmental Change Research

This living document proposes good relational practices to support climate change researchers in and beyond the Columbia University Climate School in their efforts to pursue and practice knowledge co-production in their climate-related scholarship, research, and practice. For the purpose of this document, climate researchers are anyone from any background who contributes, in any form, to enhancing our shared understanding, strategies, and responses to climate change. Although this document is focused on research, it also importantly provides communities (Indigenous and non-Indigenous alike), private sector organizations, and others who are carrying out and connected to climate-related work a window into how climate researchers might interact with them, how they can further advocate on their own behalf through the language and aspirations of co-production, and how they can anticipate interacting with researchers through co-production relational way. The document starts with a brief introduction and description of what it does and does not intend to communicate. It then transitions into a framework for good relational practices in knowledge co-production generated through an extensive review of co-production literature in the climate sciences, one-on-one conversations with 9 Columbia University affiliated researchers and practitioners, and a 2.5 day convening with 36 contributors, including Columbia researchers, Indigenous leaders, government representatives, the private sector, and external academics. The framework brings together 28 relational principles and 22 recommended good relational practices, which are summarized under the framework section. The principles and practices are then filtered into 30 reflexive questions, or points of reflection, climate researchers can ask themselves to help use and learn from the good relational practices. The principles, good practices and points of reflection are categorized into 6 interrelated pillars of co-production: The people theme brings attention to the ways in which individual and group identities shape the direction of knowledge co-production efforts. The purpose theme represents the meanings and motivations associated with knowledge co-production. The power theme refers to how power and power relations are understood and enacted through and around efforts to co-produce knowledge. The politics theme centers on the effects of policies and politics on knowledge co-production work at different scales. The pathways theme focuses on tools, approaches, and strategies used to co-produce knowledge in relevant, rigorous, and meaningful ways. The progress theme embodies the broad aspiration that knowledge co-production will catalyze transformative change, whether societal, scientific, cultural, or otherwise. The guidelines are followed with two sections about the motivations for this document and a condensed overview of the history and development of co-production within the environmental and climate sciences. The last section, Steps towards ‘good relational practices’, details how information was gathered and summarized for this document. Drawing from this information, climate researchers are encouraged to use, learn from, and reflect on the information in this document to consider why and how knowledge co-production may or may not be appropriate for their climate-related research

Negotiating identity: experiences of 'visiting home' among Chinese Americans

'Roots tourism' is loosely defined as a type of tourism in which ethnic minorities visit their ancestral lands to discover ethnic roots and culture. Despite the recent popularity of this type of tourism, many gaps remain in the study of roots tourism, particularly about its influence on the tourists’ identity. This exploratory study investigates the ways in which second and subsequent generations of Chinese Americans discuss their identity and feelings of belonging after visiting China. Face-to-face, in-depth interviews with Chinese Americans revealed that, contrary to the idea that roots tourism experiences provide individuals with strong feelings of belonging to one’s ancestral land, interviewees did not return from their visit with a feeling of connection to China. Rather, they reported a need to negotiate and redefine who they were and where they belonged. This study highlights how physical markers of Chinese identity added complexity to the negotiation of one’s identity. Because the interviewees “looked” Chinese, in a variety of situations they were automatically assumed to be Chinese while their American identity was ignored. Although Chinese Americans occasionally took advantage of such ascribed identity as Chinese, they often felt frustration, anger, and ambiguity about how they defined themselves and how others defined them. As a result of visiting China, although Chinese American tourists developed a certain sense of affinity to their ancestral land, they also affirmed that their true home was in the US. This study suggests a complexity and limitation to fostering a sense of belonging to their ancestral land through roots tourism

Commons management and ecotourism: Ethnographic evidence from the Amazon

TThe paper evaluates the relationship between ecotourism and commons management. Social and economic impacts of ecotourism in an indigenous village in the Peruvian Amazon are considered in relation to opportunities for collective action to manage common pool resources, including wildlife, forests, and river habitats. Longitudinal, ethnographic data gathered over 12 years about a joint venture ecotourism project between a private company and a local community show three outcomes that support commons management and three outcomes that challenge it. The outcomes in favor of commons management include: direct economic returns that act as conservation incentives, strengthened organization resulting from participatory management of ecotourism, and expanded networks of support from outside actors. Outcomes that are challenging the potential for collective action include: direct economic returns that enable expanded individual production and extraction, a new spirit of individual entrepreneurship that threatens to debilitate traditional social relations and institutions, and a conservation ethic that fosters dualistic thinking about people and nature and the zoning of places where resources are used vs. where they are preserved

Ecotourism and sea turtle harvesting in a fishing village of Bahia, Brazil

Many environmentalists believe ecotourism has the potential to generate net benefits for people and nature. For more than two decades, the Brazilian Sea Turtle Conservation Program (TAMAR) has provided jobs and income through ecotourism in Praia do Forte, Brazil, in exchange for reduced harvesting of sea turtles. In this article we evaluate the relationships between ecotourism at TAMAR and local support for sea turtle conservation. Nine months of ethnographic research (2006-2008) suggest that ecotourism-related employment and income have been somewhat stable and reliable. The average income of respondents who worked with TAMAR was lower than that reported by people not working with TAMAR. Workers noted other non-economic benefits. Though the majority supported sea turtle conservation, it is unclear how feelings will waver with new mass tourism developments in the region. As the cost of living increases, residents may increasingly be inclined to look for work outside TAMAR. Development also attracts new immigrants, making it difficult for locals to control sea turtle harvesting. These trends challenge the notion that economic incentives for locals alone will ensure conservation. Further research is needed to understand the conditions under which ecotourism may foster long-term conservation in the face of larger developments surrounding community ecotourism projects
