“…Crocodiles usually defend these sites, because they are "territorial " or "they are nesting" (Fisherman 7). These findings match the findings of Aranda-Coello et al (2016) and González-Desales et al (2021) who reported that the reproductive season of the crocodiles is the most dangerous period. This zoning indicates danger; nevertheless, it does not imply that fishermen avoid those sites, because they are known as places "where more fish can be found " (Fisherman 9).…”

“…Data generation was carried out through participative workshops (Geilfus, 2002;Gerritsen, 2016) that took place from January to February 2021. The participants were members of the Sociedad Cooperativa de Producción Pesquera Laguna de Alcuzahue and non-associated fisherman from both Alcuzahue and Cuyutlán.…”

“…However, most of them had been fishing for 20-30 years in coastal areas. Twentytwo fishermen attended the four participative workshops that were organized in each community, following the methodology proposed by Geilfus (2002) and Gerritsen (2016). Overall, the workshops sought to understand the fishermen-crocodile relationship.…”

Objective: To analyze the relationship between the fishermen of central western Mexico and the river crocodiles (Crocodylus acutus), emphasizing the resulting conflict. Design/Methodology/Approach: The work was carried out with 22 fishermen from the Cuyutlán and Alcuzahue lagoons in Colima, Mexico. Four participative workshops were organized per community, in order to explore the positive and negative aspects of the relationship, the perception and knowledge about the ecosystem functions of the crocodile, and the management practices and actions associated with this relationship, as well as to determine the natural participants and factors that influence the said relationship. The workshops were recorded and the resulting data was subjected to a narrative analysis and a summary. Results: Harmonious relationships are recorded, including the creation of bonds between humans and crocodiles and recognizing the benefits to fishing and the ecosystem function of the crocodile. The conflictive relationships identified were related to fishing, the reduction of fishing resources, and accidents. The strategies used to prevent conflicts are related to the dangerous zones, the behavior of the crocodiles, and the killing of the animals to reduce their presence. Additionally, compensation schemes, a collective management of fishing resources, and the replacement of fishing by the exploitation and capture of the crocodile were taken into consideration. Study Limitations: Besides the fishermen’s, the point of view of other participants should be determined. Conclusions: The relationship between fishermen and crocodiles is both harmonious and conflictive. On the one hand, both receive benefits; on the other hand, fishermen suffer economic, operative, and life style impacts, which create inauspicious scenarios for the conservation of the reptile.

“…Across their global range, crocodilians are frequently involved in negative interactions with people (Gonzalez-Desales et al, 2021). Such negative interactions appear to be increasing across Africa because of human population growth, which in some areas coincides with a recovery of crocodile populations (Aust, 2009).…”

Interactions between people and wild animals often result in negative impacts, and different views on the management of such interactions can lead to conflicts. Both intentional and unintentional negative human–wildlife interactions are increasing problems in many places where people share space with wild animals. Here we focus on negative interactions between people and Nile crocodiles Crocodylus niloticus in and around Lake Kariba in Zimbabwe. In the study area, crocodile attacks on people occur frequently, leading to people being injured or killed, which in turn prompts retaliatory actions against crocodiles. However, despite the negative impact of such interactions on both people and crocodiles, little is known about the spatio-temporal patterns of crocodile attacks or environmental conditions under which attacks occur. We collected information about crocodile attacks on people that occurred during 2000–2020, including the date, time, season and location of attacks, the age of victims and the activities they were carrying out when attacks occurred, and water conditions during attacks. We analysed these data to discern patterns and trends of crocodile attacks on people. Attacks occurred in clear as well as turbid water, and nearly half of all reported attacks were at night or in the early morning. The locations with the highest number of recorded attacks were Nyanyana and Charara lakeside, and the fewest attacks occurred at Andora harbour. Most victims were 26–40 years old, and most were attacked in the dry-hot season, while they were fishing. Our findings can be used to design area-specific mitigation strategies to reduce negative human–crocodile interactions.

“…In Latin American and Caribbean countries, negative interactions between humans and crocodilians have increased by 39% between 2018 and 2020 (Pooley et al 2021b). This may cause fatal incidents involving humans (as documented in Colombia by Balaguera-Reina and Farfàn-Ardia 2018 and in Mexico by García-Grajales and Buenrostro-Silva 2019), and destruction of natural sites due to greater anthropogenic activity (González-Desales et al 2021). In Brazil, several anthropogenic activities threaten crocodilian populations, such as hydroelectric dams (Campos 2015), roads (Campos et al 2012), illegal hunting Da Silveira and Thorbjarnarson 1999;Mendonça et al 2016;Mourão et al 1996;Muniz et al 2021) and urbanization (Mascarenhas-Júnior et al 2018).…”

Crocodilian-human conflicts, caused especially by urban expansion and habitat destruction, have been considered one of the main threats to the conservation of these species worldwide. In Brazil, such conflicts have been documented with crocodilian species all over the country. This study identified 400 conflict events in on-line journalistic news between humans and caimans within Brazilian cities between 2016 and 2021. Caiman latirostris (57.3%) was the most common species found in large urban centers in the Northeastern and Southeastern regions. Most encounters in which the date was informed were registered in the wet season (64.5%), and the rescues were mainly carried out by the environmental military police and fire brigades. We outlined management protocols to be undertaken by environmental agencies during crocodilian rescues to minimize animal stress and risk of accidents. The increasingly common interaction between humans and caimans in urban environments is an important alert to envisage best conducts for the coexistence between people and caimans in Brazil and shows the need to invest in public policies to mitigate the negative effects of urbanization on wildlife.
