Local communities, for instance, had their local coping strategies that enabled them to stay in their communities even amid these ordeals, and climate change disaster threats. This work strives to understand flood impacts and the local peoples’ adaptation or coping strategies along the River Gambia basin. A community-based cross-sectional research study of 422 research participants of which 294 are males (69.7%) and females 128 (30.3%), and a focus group discussion of 10 groups which comprised 5 female groups and 5 male groups respectively found that 98.6% of the households experienced floods in their community, and 70.6% experienced flood in their houses, 2.1% have impending flood information and 88.4% do not know evacuation centres. The majority of the households had some local coping strategies, but they acknowledged their insufficient effectiveness. The result also shows that the impact of floods on farmlands, roads, buildings, and livestock was greatly felt. Coping strategies such as sandbags, raised elevations, contour bonds, dikes, and buildings on highlands were all found to be common mechanisms the local people used. The study opines that floods affect communities, but the effects vary depending on individual assets.展开更多

This collaboration promotes community-based welfare and inspires a sense of responsibility, thus promoting more benefits than conflicts. A survey administered to residents surrounding Nyungwe National Park was used to evaluate the relationship between Nyungwe National Park management and local communities. The residents acknowledged a positive attitude towards participating in conservation organizations where there was involvement, while a negative response revealed weak community mobilization. The community’s opinions about protection and tourism progression noted weak conflict resolution, but a positive attitude towards tourism activities in the area since they believed employment was likely as a result. In addition, the residents asked for support from government investments and stakeholders to develop the local private sector, and asked to be involved during the planning process. Approaches including the design of coordination mechanisms and integrated conservation and developments projects are suggested to promote a management structure leading to community involvement in conservation and tourism activities. This will increase visitor numbers and contribute to economic development not only in the region but also in the whole country. Empirical studies along with the factors shaping tourism and conservation activities should be considered as the basis for sustainable decision and policy making for sustainable management, and will contribute to government, stakeholders and park manager collaborations at Nyungwe national park.展开更多

Thus their conservation policies are mainly shaped according to this Western perspective. After the spread of international doctrines in conservation of cultural heritage to other parts of the world, it was realized that some archaeological sites were more than group building remains. They were pilgrim sites for the local communities continuously for centuries onwards. Even in some cases, they have traditional management systems to take care for the site. This has raised the awareness about the gaps in modern heritage conservation approaches. International organizations have mentioned about the involvement of local groups in heritage management systems considering their traditional and cultural association with the cultural site. This has provided shifting of conservation approaches from conventional approaches towards living heritage approach in such delicate cultural heritage sites. The purpose of this paper is to discuss the historic generation of policies towards local communities living on archaeological sites in Turkey comparing the policies between living （on） archaeological sites and living archaeological sites approach.展开更多

To reveal the understanding of the local people regarding the potential health risks of bushmeat consumption and handling of wildlife products, we used a semi-structured questionnaire to survey 261 households in eight villages located adjacent to the western part of Nyerere National Park. Also, we interviewed eight key informants, including conservation personnel and veterinary officers, in the study area. The proportion of local people who were unaware that handling of wildlife products and bushmeat consumption were risky behaviours towards acquiring zoonotic diseases was slightly higher (57%) than the proportion of respondents who were aware of the likely risks of zoonotic diseases from the practices. After all, the majority (83%) of local people admitted having come into contact with wildlife products, while over 70% reported having consumed bushmeat. We found that local communities living closer to the park boundaries (<15 km) have a higher likelihood of contacting wildlife products, and that community members who have lived in the area for more than ten years have experienced more contact with wildlife products than immigrants. Moreover, the age of inhabitants and length of stay were found to be the most significant factors in determining the likelihood of bushmeat consumption. Most people seemed to prefer bushmeat to domestic meat, arguing that bushmeat is far more flavorful, tender, not tainted with chemicals, and has less fat, making it safer. Our study demonstrated that local communities participate in risky practices without contemplating the health consequences that could emerge should a zoonotic disease outbreak occur. Among other strategies, we recommended conservation and public health institutions to increase awareness campaigns on the possible health risks of zoonotic diseases associated with wildlife.展开更多

To analyze the perception and attitudes of local communities, the Participatory Rural Appraisal (PRA) was used in the investigation of 423 interviewees from 22 villages in Xishuangbanna from July 2009 to February 2010. The results indicated that local communities had their views on the elephant-related problems. In field survey, we found that 66.5% of interviewees were willing to support, participate in, and assist in the conservation of wild elephants;33.5% of interviewees were opposed or indifferent to such conservation, because their livelihoods and even their lives were endangered by wild elephants. These views and attitudes were influenced by local communities′perception of HEC, education level, gender and self-interest. Therefore, it is necessary to analyze the diverse views among local communities and balance profits and costs in addressing HEC.展开更多

It is a plausible way of involving local communities in the planning and management of the available resources for their sustainability. This study examined the socio-economic characteristics of the households in Murchison Falls Conservation Area to understand how they influence their participation in tourism and eventually enhance household welfare. Using household survey and key informant interviews, data were collected on demographic and socio-economic characteristics of the respondents and analyzed using Binomial Logit Regression in order to show the factors that influence participation of households in tourism. It was found that the households＇ characteristics significantly influenced their participation. In particular, level of education （r = 0.824）, engagement in farm labor （r = 0.651）, provision of services to the tourists （r = 0.841）, income （r = 0.83） and landholding （r = 0.689） significantly influenced households＇ participation in tourism. On the other hand, age （r = 0.59） and period of residence （r = 0.430） did not significantly influence the households＇ participation in tourism. These results suggest that a clear understanding of the households＇ socio-economic characteristics is a vital step in engaging them meaningfully in tourism activities meant to enhance their livelihoods. Equally important is the need for tourism managers and local government leaders to consider these characteristics when designing policies and strategies to enhance community involvement and management of tourism at a conservation area level.展开更多

These include changes in the function of settlements, population size, location of residence, and the movement of local culture. This study aims to examine the spatial changes that occur in local neighborhoods with a focus on the Bantik tribal community in Malalayang. Data were obtained from a series of field observations, questionnaires and structured interviews. This study conducted a series of analyses on spatial patterns, sociocultural factors and urban policy. The results show that the dynamic changes are natural and hard to avoid, since they are related to the community＇s needs and development of the city. In order to face the changes, adjustments in the values of the local community towards the settlement terms and conditions are necessary. In addition, an increase in internal resources for those local communities is needed.展开更多

This species is protected in Democratic Republic of Congo (DRC) and worldwide, unfortunately it is threatened by numerous human actions. The purpose of this study was to determine the profiles of actors using pangolins, the reasons for pangolin exploitation and its products and their use within the local community in and surrounding the reserve. We carried out surveys in the households of hunters, farmers and people practicing other professions in 12 villages, located within the Tayna Nature Reserve (RNT) and surroundings areas. Two interview techniques were used: the individual interview and the participatory diagnostic technique. During one month of data collection, 175 respondents were interviewed. Respondents had diverse profiles according to sex, age, education level and ethnicity. Men were more represented as actors in pangolin exploitation (71.70%) than women (28.30%);the most represented age interval was 20 - 30 years. The education level is distinct amongst respondents: illiterate (37%), primary school (32.4%) and graduate from university (2.9%). An average number of respondents are motivated to consume pangolin as meat obtained by hunting at 50%. The main reason for its consumption is preference (44%) and habit (33%). The scales are pangolin derivatives most recognized by local people and widely used in the pharmacopoeia. Consequently, pangolin protection needs some rigorous measures to reinforce the current law implementation.展开更多

文摘The problem of wild elephants, or human-elephant conflict (HEC), influences the daily life of local communities and hinders the conservation of wild elephants.The perception and attitudes of local communities who inhabited the frontiers between human activities and wild elephant movement are important to the mitigation of the HEC and conservation of wild elephants. To analyze the perception and attitudes of local communities, the Participatory Rural Appraisal (PRA) was used in the investigation of 423 interviewees from 22 villages in Xishuangbanna from July 2009 to February 2010. The results indicated that local communities had their views on the elephant-related problems. In field survey, we found that 66.5% of interviewees were willing to support, participate in, and assist in the conservation of wild elephants;33.5% of interviewees were opposed or indifferent to such conservation, because their livelihoods and even their lives were endangered by wild elephants. These views and attitudes were influenced by local communities′perception of HEC, education level, gender and self-interest. Therefore, it is necessary to analyze the diverse views among local communities and balance profits and costs in addressing HEC.

文摘Community＇s participation is fundamental in understanding the factors that influence their access to and utilization of tourism resources. It is a plausible way of involving local communities in the planning and management of the available resources for their sustainability. This study examined the socio-economic characteristics of the households in Murchison Falls Conservation Area to understand how they influence their participation in tourism and eventually enhance household welfare. Using household survey and key informant interviews, data were collected on demographic and socio-economic characteristics of the respondents and analyzed using Binomial Logit Regression in order to show the factors that influence participation of households in tourism. It was found that the households＇ characteristics significantly influenced their participation. In particular, level of education （r = 0.824）, engagement in farm labor （r = 0.651）, provision of services to the tourists （r = 0.841）, income （r = 0.83） and landholding （r = 0.689） significantly influenced households＇ participation in tourism. On the other hand, age （r = 0.59） and period of residence （r = 0.430） did not significantly influence the households＇ participation in tourism. These results suggest that a clear understanding of the households＇ socio-economic characteristics is a vital step in engaging them meaningfully in tourism activities meant to enhance their livelihoods. Equally important is the need for tourism managers and local government leaders to consider these characteristics when designing policies and strategies to enhance community involvement and management of tourism at a conservation area level.

文摘In recent years,local community detection algorithms have developed rapidly because of their nearly linear computing time and the convenience of obtaining the local information of real-world networks.However,there are still some issues that need to be further studied.First,there is no local community detection algorithm dedicated to detecting a seed-oriented local community,that is,the local community with the seed as the core.The second and third issues are that the quality of local communities detected by the previous local community detection algorithms are largely dependent on the position of the seed and predefined parameters,respectively.To solve the existing problems,we propose a seed-oriented local community detection algorithm,named SOLCD,that is based on influence spreading.First,we propose a novel measure of node influence named k-core centrality that is based on the k-core value of adjacent nodes.Second,we obtain the seed-oriented local community,which is composed of the may-members and the must-member chain of the seed,by detecting the influence scope of the seed.The may-members and the must-members of the seed are determined by judging the influence relationship between the node and the seed.Five state-of-art algorithms are compared to SOLCD on six real-world networks and three groups of artificial networks.The experimental results show that SOLCD can achieve a high-quality seed-oriented local community for various real-world networks and artificial networks with different parameters.In addition,when taking nodes with different influence as seeds,SOLCD can stably obtain high-quality seed-oriented local communities.
文摘The Proximity between the central business district and the settlement has led to many changes in the local Bantik community. These include changes in the function of settlements, population size, location of residence, and the movement of local culture. This study aims to examine the spatial changes that occur in local neighborhoods with a focus on the Bantik tribal community in Malalayang. Data were obtained from a series of field observations, questionnaires and structured interviews. This study conducted a series of analyses on spatial patterns, sociocultural factors and urban policy. The results show that the dynamic changes are natural and hard to avoid, since they are related to the community＇s needs and development of the city. In order to face the changes, adjustments in the values of the local community towards the settlement terms and conditions are necessary. In addition, an increase in internal resources for those local communities is needed.

文摘Climate change affects both men and women which,in turn,shapes their varied and contrasting perceptions of climate variability and change.This paper examined the gendered perceptions of climate variability and change among local communities in Queen Elizabeth National Park in Uganda.The objectives are threefold:-identify climatic shocks faced by the local communities;examine the perceptions of men and women of climate variability and change;and to compare their perceptions with empirical meteorological data.This study employed both qualitative and quantitative methods,with data collected from 215 respondents using survey,interviews and focused group discussions.From the findings,indicators of climate variability and change included reduced flooding events,occurrence of human diseases,increasing crop pests and diseases,dry spells and intensity of rains.There was increasing significant temperatures while rainfall was declining.Both male and female significantly associated with increasing temperatures and reduced flooding events.While climatic shocks affected both males and females,the impact was more pronounced depending on distinct livelihood activities and roles and responsibilities undertaken.The study concluded that people’s perceptions of climate change should be taken on by the government and integrated in the national climate programs that support people’s livelihoods and survival mechanisms.

文摘Pangolin exploitation has recently increased in diverse forms such as bushmeat consumption;species or parts trade, medical use. This species is protected in Democratic Republic of Congo (DRC) and worldwide, unfortunately it is threatened by numerous human actions. The purpose of this study was to determine the profiles of actors using pangolins, the reasons for pangolin exploitation and its products and their use within the local community in and surrounding the reserve. We carried out surveys in the households of hunters, farmers and people practicing other professions in 12 villages, located within the Tayna Nature Reserve (RNT) and surroundings areas. Two interview techniques were used: the individual interview and the participatory diagnostic technique. During one month of data collection, 175 respondents were interviewed. Respondents had diverse profiles according to sex, age, education level and ethnicity. Men were more represented as actors in pangolin exploitation (71.70%) than women (28.30%);the most represented age interval was 20 - 30 years. The education level is distinct amongst respondents: illiterate (37%), primary school (32.4%) and graduate from university (2.9%). An average number of respondents are motivated to consume pangolin as meat obtained by hunting at 50%. The main reason for its consumption is preference (44%) and habit (33%). The scales are pangolin derivatives most recognized by local people and widely used in the pharmacopoeia. Consequently, pangolin protection needs some rigorous measures to reinforce the current law implementation.

文摘Encouraging citizens to invest in small-scale renewable resources is crucial for transitioning towards a sustainable and clean energy system.Local energy communities(LECs)are expected to play a vital role in this context.However,energy scheduling in LECs presents various challenges,including the preservation of customer privacy,adherence to distribution network constraints,and the management of computational burdens.This paper introduces a novel approach for energy scheduling in renewable-based LECs using a decentralized optimization method.The proposed approach uses the Limitedmemory Broyden–Fletcher–Goldfarb–Shanno(L-BFGS)method,significantly reducing the computational effort required for solving the mixed integer programming(MIP)problem.It incorporates network constraints,evaluates energy losses,and enables community participants to provide ancillary services like a regulation reserve to the grid utility.To assess its robustness and efficiency,the proposed approach is tested on an 84-bus radial distribution network.Results indicate that the proposed distributed approach not only matches the accuracy of the corresponding centralized model but also exhibits scalability and preserves participant privacy.
文摘The Safe Schools Declaration of 2015 is an inter-governmental political agreement signed by several countries designed to protect the schooling of the school-aged population during armed conflicts.Yet,in countries where civil war erupted,schools were demolished.Several school-aged children were either forcibly recruited by governments or coerced by rebel groups to serve in armed fights.As a result,several children were deprived of their education and have remained suffering from deep psychological scars.The central question of the study is:What kind of sustainability-driven school buildings can be initiated in countries that are now enduring peace so that the learning environments are more comfortable and improve the well-being of the war-impacted children and school employees?After reviewing the literature,a strategic conceptual framework that incorporated the synergistic relationship between economic,social,and environmental aspects of sustainability was initiated to map out sustainable school buildings.In short,the conceptual framework proposed to construct school buildings in some of the war-affected developing countries includes assembling cost-efficiency and eco-effectiveness inputs,using renewable energy sources powered by natural sunlight,collecting rainwater in mud cisterns,reducing emissions of carbon oxides,and empowering the local community to be the main actors to design sustainable buildings during the preconstruction,construction,and post-construction stages to serve as learning spaces for the war-affected occupants and their neighborhoods.
