“…A pesar de las carencias antes mencionadas, los resultados obtenidos por el análisis del contenido de la narrativa de este trabajo demuestran algunos aspectos generales relacionados con los conflictos, mismos que se concentran en tres temas (Figura 2): los ataques a humanos y al ganado, así como los impactos a la pesca, temas comunes también en otras investigaciones distintas a las encontradas en la búsqueda sistemática, por ejemplo: Caldicott et al, 2005;Chakanyuka & Utete, 2022;Uluwaduge et al, 2018;Whitaker & Srinivasan, 2020. Los ataques a mascotas fueron tratados en menor medida, pero de igual manera que los temas antes mencionados, el contenido narrativo presenta similitudes con estudios no incluidos en esta investigación debido a su metodología o a ser literatura gris.…”

“…recolección de leña o bañarse en el río) o situaciones laborales (ej. producción de hortalizas), todas realizadas cerca del agua, esta cercanía ha sido asociada por otras investigaciones también como generadora de accidentes (Caldicott et al, 2005;Uluwaduge et al, 2018), pero no explica totalmente los accidentes. Así, se suman a las explicaciones acciones o cualidades de las personas, o el tipo de infraestructura disponible donde se sufrió el accidente, como ejemplo de esto tenemos conceptos como "entrometerse en el hábitat", lo cual hace referencia a un territorio donde el humano es ajeno, también se mencionaron comportamientos inadecuados, como son ignorar el comportamiento de estos reptiles, condicionarlos con alimento (directa o indirectamente), lo que genera "demasiado contacto" entre ambos (Keul, 2013), es decir, un contacto que genera condiciones propicias para el accidente, sin embargo, Caldicott et al, (2005) en su revisión bibliográfica donde analiza accidentes con cocodrilos sostiene que esto no siempre fomenta los ataques.…”

El resultado de la interacción entre humanos y fauna produce escenarios donde la conservación y el desarrollo local sustentable se comprometen. Aunque es un tema relevante por sus implicaciones, no existen estudios que hayan sistematizado el conocimiento generado con respecto a las especies involucradas y las características del conflicto. Esta investigación, a través de una revisión sistemática de bases de datos y un análisis narrativo de contenido, identifica y analiza el conflicto humano-cocodrilo a nivel mundial en 28 artículos, con base en el origen y tendencia de las investigaciones, especies involucradas y tipo de interacción. La relación conflictiva es explicada a través de aspecto biológicos como la reproducción o dieta del saurio, así como de su crecimiento poblacional o demográfico, pero también de factores ambientales como el nivel de agua o temperatura, se identificaron las repercusiones económicas y para la conservación de las especies asociadas a este conflicto. Dominan los estudios centrados en ataques a humanos, en el continente americano y para la especie Crocodylus acutus. Los efectos del cocodrilo fueron directos (ataque a humanos) e indirectos (daños a la pesca, agricultura, ganadería, mascotas). El conflicto de intereses entre grupos sociales, así como los aspectos ligados a cultura, percepción, religión u otras cualidades sociales, fueron poco abordados por los artículos analizados.

“…After identifying such spots, 'Crocodile Excluding Enclosures' could be constructed using indigenous material for safety of people who share the habitat with the reptile. Such approach has been effectively tried in Sri Lanka (Uluwaduge et al 2018). Poverty alleviation and community development initiatives could help lessen the dependence of locals on this river and consequently move them away from conflict.…”

In this paper, we report monitoring of a resident population of Mugger Crocodile Crocodylus palustris (Lesson, 1831) along a stretch of 3.5 km of the river Savitri on the outskirts of Mahad town of Raigad District in Maharashtra, on monthly basis from 2014 to 2021. This river is increasingly becoming a sink of anthropogenic wastes emerging from adjacent settlements impacting its habitat value, and puts the reptile side by side with humans and human-wastes that could be a cause of rising incidents of crocodile mortality in the recent times here, as also reported from elsewhere. Savitri River has been a fishing ground for local indigenous communities, who also use the river bank for washing clothes and utensils, and for swimming. Such proximity between people and crocodiles creates a potential for negative interaction. This long term study monitored the Mugger population trends for the last eight years at four transect stretches along the river. Counts are suggestive of a healthy viable population of Mugger in this river currently, but a future conflict situation cannot be ruled out. Being generalist feeders, Muggers can sustain themselves on fish, and scavenge on dumped carrion and other anthropogenic organic wastes. With the exception of a few sporadic incidents of aggression by the Muggers at this location, no human casualties have been reported thus far, however, this does not rule out fatal reciprocal interactions in future and hence a few practical mitigation measures have been suggested.

“…For example, resurgent Nile crocodile ( Crocodylus niloticus ) populations in Namibia have increasingly come into conflict with humans in areas now used for cattle ranching (Aust et al, 2009 ), and estuarine crocodiles ( Crocodylus porosus ) in Malaysian Borneo are becoming common residents of oil palm plantations (Evans et al, 2016 ). While there have been a few studies of crocodilian populations in human‐dominated areas, most have aimed only to investigate population distribution and habitat use (e.g., Beal & Rosenblatt, 2020 ; Eversole et al, 2018 ; Skupien & Andrews, 2017 ), rates of human–crocodile conflict (e.g., Garcıa‐Grajales & Buenrostro‐Silva, 2019 ; Uluwaduge et al, 2018 ; Wallace et al, 2011 ), or population management techniques (Kidd‐Weaver et al, 2022 ). As a result, it remains unclear how crocodilian ecology, and especially feeding patterns, might shift in areas that have undergone land use change.…”

Human‐driven land use change can fundamentally alter ecological communities, especially the diversity and abundance of large‐bodied predators. Yet, despite the important roles large‐bodied predators play in structuring communities through feeding, there have been only a few investigations of how the feeding patterns of large‐bodied predators change in human‐dominated landscapes. One group of large‐bodied predators that has been largely overlooked in the context of land use change is the crocodilians. To help fill these gaps, we studied the feeding patterns of juvenile American alligators (Alligator mississippiensis) on neighboring barrier islands on the southeast coast of Georgia, USA. Jekyll Island has multiple golf courses and substantial amounts of human activity, while Sapelo Island does not have any golf courses and a much smaller amount of human activity. We found that juvenile alligator populations on both islands ate the same types of prey but in vastly different quantities. Sapelo Island alligators primarily consumed crustaceans while alligators that lived on Jekyll Island's golf courses ate mostly insects/arachnids. Furthermore, the Jekyll Island alligators exhibited a much more generalist feeding pattern (individuals mostly ate the same types of prey in the same quantities) than the more specialized Sapelo Island alligators (diets were more varied across individuals). The most likely explanation for our results is that alligators living on golf courses have different habitat use patterns and have access to different prey communities relative to alligators in more natural habitats. Thus, land use change can strongly alter the feeding patterns of large‐bodied predators and, as a result, may affect their body condition, exposure to human‐made chemicals, and role within ecological communities.
