“…This shows that carnivore predation information collected through LEK and the standard protocols used by DWNP were complementary. Similar results have been observed with other species such as tortoise distribution in south-eastern Spain (Anadón et al 2009), fish and fisheries management in the Beaufort Sea, Canada (Hartwig 2009b), southern Mexico (Espinoza-Tenorio et al 2013), south-eastern Brazil (Teixeira et al 2013) and wild mammals in northern Gonarezhou National Park, Zimbabwe (Gandiwa 2012). The results further show that both LEK and PAC data were in agreement over the fact that lion predation decreases with increasing distance from protected areas ( Figure 3a) and leopard incidents were evenly distributed throughout the study area (Figure 3b).…”

Botswana is one of the countries in Southern Africa that pay compensation for human properties damaged by wildlife. Before compensation is paid, a thorough investigation on determining wildlife species that have caused the damage is mandatory. Because of insufficient resources by the Department of Wildlife and National Parks, the initial investigation is carried out by herders. Three basic indicators are used to determine carnivore predation; sighting the carnivore at the kill, tracks of the predator and examining the carcasses. In this study, we tested herders’ knowledge on the above three indicators. The study was conducted in a communal area around Makgadikgadi and Nxai national parks, Botswana, where the main activities practiced by the local communities is pastoral farming. In general, there was a significant association between reported and perceived incidents of predation for all carnivores at all distances from protected areas. Herders were able to identify the large carnivores visually. But they had difficulties in identifying carnivore tracks and kill characteristics. The results demonstrate the importance of involvement of local communities in human–wildlife conflict management. However, more education regarding identification of carnivore tracks and kill behaviour is needed for herders in the study area.Conservation implications: Based on the results of this study, this calls for a change in the management of human–wildlife conflict (HWC) and administration of the compensation scheme. Decentralising HWC to local communities using existing government structures that exist at local level will not only supplement the inadequate resources by the Department of Wildlife and National Parks (DWNP) to effectively mitigate the problem, but also empower local communities’ participation in wildlife management.

“…This classification was especially evident for the middle and outer portions, where several valleys dissecting the shelf were observed. In south Espírito Santo, based on surveys by [7], the accommodation system also dominates this portion of the shelf, which comprises low terrigenous mud and sand contents, while carbonate gravel and rhodolith dominate the shelf.

Seabed Morphology and Sedimentary Regimes defining Fishing Grounds along the Eastern Brazilian Shelf

et al. 2018

Shelf morphology and sedimentary regimes are influenced by processes operating at different temporal and spatial scales and are important records of sea level changes and sediment supply and/or carbonate production. The northern continental shelf of Espírito Santo (Brazil) contains evidence of different sedimentary regimes that distribute diverse and complex marine habitats. Herein, seabed morphology, acoustic images of the seafloor (side scan sonar and sub-bottom profiler), and sediment samples were used to investigate the influence of sedimentary regimes on physical marine habitat distribution. Seabed mapping is also integrated with available data on fisheries to understand the influence of shelf morphology and sedimentology in the usage of distinct fishing gears. The results indicate five morpho-sedimentary facies: terrigenous mud, terrigenous sand, rhodolith beds, carbonate gravel with rhodoliths, and hardground. Through an integrated analysis of the geomorphology and sedimentary distribution, two morpho-sedimentary domains were identified: a sediment-fed shelf adjacent to the Doce River associated with a major mud depocenter and a delta front morphology characterized by gentle slopes and low terrain ruggedness, and a sediment-starved shelf dominated by carbonate sedimentation showing an irregular morphology associated with higher slopes and terrain ruggedness. These contrasting morpho-sedimentary domains are a result of sedimentary responses to sea level fluctuation during Late Quaternary, specially, during the deglaciation processes after the Last Glacial Maximum. The morphological and sedimentary contrasts along the area define the physical habitat distribution. The sediment supply regime area is associated with a terrigenous fine/muddy sedimentation bed, which control the local morphology and favors coastal and delta front progradation. This physical habitat is a well-known shrimp-fishing ground where intense trawling takes place, as well as gillnet fisheries targeting weakfish and croakers. The accommodation regime or low sediment influx area is characterized by carbonate sedimentation associated with hardgrounds and rhodolith beds. In contrast, this physical habitat with scarce sediment supply, facilitates extensive benthic colonization by crustose coralline algae (CCA), which is primarily associated to line fisheries, longlines, and spearfishing. Rhodoliths show a high diversity of CCA and the occurrence of an endemic kelp species. Long-term processes such as relative sea level fluctuations and sediment supply are a legacy for the distribution of benthic

“…WCED 1987;Mebratu 1998;Fernandez-Gimenez et al 2016), scientists and ecological practitioners started to revaluate TEK held by communities that are strongly engaged in traditional subsistence systems (Menzies 2006;Martin et al 2010). Scientists have tried to better integrate TEK with modern approaches of natural resources management and conservation strategies in different domains of human-environment interactions, such as inland and marine fisheries in Brazil (Schafer and Reis 2008;Teixeira et al 2013), forestry and traditional rice-farming in Japan (Indrawan et al 2014), as well as small mammals' conservation in the Dominican Republic (Turvey et al 2014), and positive effects of the approach were reported.…”

The relevance of herders’ local ecological knowledge on coping with livestock losses during harsh winters in western Mongolia

In many regions of the world, traditional and local ecological knowledge is still important today for coping with environmental challenges. This study explored the relevance of such knowledge for predicting and coping with harsh winter conditions (dzud) in a remote area of western Mongolia, where government support to disasteraffected herders is restricted by weak infrastructure. Structured face-to-face interviews were held in 50 households (HHs), addressing aspects of livestock possession and management as well as disaster prediction and mitigation. The responses disclosed that livestock losses during the 2009/10 dzud averaged 112.4 animals per HH, equaling nearly 80% of the interviewees' total livestock possession in summer 2013. To reduce such high losses in the future, herders planned to improve their hay-making efforts and winter pen preparation. However, they also stated that the earliest signs for a dzud occur in September, when it is already too late for substantial hay-making. Therefore, some herders underlined the necessity of maintaining livestock productivity through segregated summer grazing of specific animal groups, controlled mating and early sale of weak livestock. Animals are then entering a harsh winter in good body condition. National and international organizations wishing to support livestock keepers in this and similar regions should therefore highlight the relevance of local strategies for disaster prevention and support community-based approaches that can compensate for the prevalent lack of family labour.
