Elephants capture the affection of people but also inspire animosity and fear at the same time. This is because there are conflicts with people over space, critical resources, costs of damages and general insecurity to people. This paper examined field evidence and interviewed expert key informants on current intensity and frequency of human-elephants in Amboseli Ecosystem. According to them, generally, the most prevalent (score of 1 lowest to 10 highest) threats to elephants were competition for critical resources (6.32 ± 0.44) followed by blocking of migration (6.24 ± 0.46), harassment of elephants (4.83 ± 0.75), poaching (4.57 ± 0.37), and retaliatory killings (3.78 ± 0.31). For threats that elephants pose to people, the most prevalent one was crop raiding (6.95 ± 0.26) followed by environmental degradation (6.71 ± 0.46), general insecurity to people (5.76 ± 0.65), property destruction (5.16 ± 0.41), injury and death to livestock (3.78 ± 0.37), and injury and death to people (2.71 ± 0.27). For the severity of the threats, the highest score was given to crop raiding whose average score was 7.90 ± 0.24 followed by environmental destruction and degradation (6.89 ± 0.43), injury and death to people (6.72 ± 0.44), injury and death to livestock (6.36 ± 0.50), property destruction (5.78 ± 0.49), general insecurity to people (5.62 ± 0.64). Severity levels followed the same trend or varied slightly. These drivers of human-elephant conflicts need to be addressed decisively to protect both people and elephants. There is a need to ensure local people’s benefit from elephants through ecotourism investments such as wildlife sanctuaries, leasing critical space for elephants’ dispersal on acceptable terms, through appropriate compensation schemes for elephant costs, and supporting local community wildlife rangers to prevent conflicts.展开更多

Most carnivores involved in such conflicts are: lion, hyena, leopard and cheetah. Three strategies are normally used in Kenya to mitigate such conflicts;consolation for lost livestock and human life to increase tolerance to them, use of predator proof homesteads especially among pastoralists, use flicking lights at night to discourage approach of carnivores near homesteads, and awareness creation among communities on the ecological role of carnivores. This study examined human-carnivore interactions in privately owned conservancies near Amboseli National Park, Kenya. The conservancies were found to have almost similar human and livestock demography. However, homesteads in Elerai had more fence broken parts and relatively higher levels of livestock predation by lion and hyena. The higher the number of each livestock type was, the higher the specific predation to that livestock type was, implying density dependent effects of predation by carnivores on livestock. It seemed that the fence structure and level of maintenance (including carnivore strategies on specializing on specific livestock size and age consistent with optimizing their foraging strategies) influenced predation incidences. However, the presence of adult males and Maasai warriors (morans) in bomas did not seem to be related with the number of livestock killed by carnivores, implying that they didn’t add vigilance as an additional strategy to prevent livestock depredation. It is recommended that attention be paid on maintenance of homestead and livestock fences as well as vigilance to deter predation. We further recommend strategies to prevent livestock predation such as, installation of chain link predator proof fences or carnivore lighting deterrents at night because woody plants fences are ineffective and deteriorate easily with time, and also lead to depletion of plant resources critical to households.展开更多

There are only a few swamps outside Amboseli National Park available to the Maasai, livestock and wildlife. Such swamps may disappear in the near future because of conversion to cultivation. This study established the current size and threats to Kimana and Ilchalai near Amboseli National Park. Swamps were regularly used by over 15 large mammal species among them elephants, buffalo, wildebeest, zebra, gazelles and hippopoatums. However, only 15.7% of Kimana Swamp and 36.1% of Ilchalai Swamp remained unconverted to cultivation, with the rest of the remaining swamp area converted to agriculture. Cultivation was mainly done by non–Maasai land leasers, and for mainly commercial purposes. Swamps were converted because of adequate and free water, cheap lease fee, and their fertile soils. Although concerned with swamp conversion, most cultivators were ready to expand cultivation in other swamps. These findings demonstrate how unsustainable resource use and swamp conversion can seriously threaten critical resources for local livelihoods and wildlife conservation.展开更多

Burning biomass is one of the major contributors to carbon dioxide (CO2) emission—a principle gas in global warming and climate change. One way of cutting down the CO2 emissions is adaptation of efficient and clean energy technologies. This study examined the efficiency of the energy saving stoves in Amboseli ecosystem by comparing the cooking time, energy use, wood fuel and carbon emissions to the traditional three stone open fire set ups. The result indicates a statistical difference in the time spent cooking on energy stoves and three stone open fire (t = 5.3055;n = 60;p = 0.00117). Energy saving stoves saved 12.7% - 33.3% of wood fuel compared to the traditional three stones set ups. Water boiling tests to determine the energy savings, revealed that energy saving stoves saved between 25.74% and 26.16% energy/joule per session in-house and outdoor settings respectively. Based on the two meals prepared per day by each household, the total Carbon Emission Savings for the 1000 local beneficiaries of energy saving stoves varied from 102,200 kg CO2 (indoor cooking) to 357,700 kg CO2 (outdoor cooking) per year. It is therefore concluded that energy saving stoves saves time, fuel wood and energy, and reduces carbon emissions. The study findings refute the claims that open fire when carefully operated can be fuel efficient and clean burning to rival energy saving stoves. To improve the performance of the energy saving stoves, it is recommended that a design modification be done to include a chimney to emit excess smoke during indoor cooking;and the stove should be fixed to the floor with mortar to minimise heat loss and breakages.展开更多
