These conflicts create real threats both for the survival of wildlife species and of human beings. This study was carried out at the periphery of Loango National Park in Gabon. This area is particular of seeing elephants wandering around villages. Respondents for the study were drawn from a wide range of stakeholders (State administrators, farmers and NGOs). Data was collected through administration of structured questionnaires and interview guide on the;socio-economic activities. Crops produced/destroyed. Animals are involved and economic loss is incurred due to conflicts. Data was analysed using SPSS version 16 and Kobo tool box. For qualitative data chi-square, descriptive statistic and linear regression model were also used. The results of the study showed that the elephants account for (60.1%) of crop destroyed followed by Ungulates (30.4%) and lastly by rodents (0.9%). The economic damage caused by the wildlife to crops valued at 72,084 USD in the zone in 2022. An urgent solution to this conflict is needed because the consequences are visible as well as the illegal repression by communities that have led to poisoning and killing of wildlife in the study area.展开更多

The regional, karst Floridan aquifer system underlies the United States (US) Southeastern Coastal Plain Physiographic Region and exhibits hydrologic interconnections with overlying surficial aquifers and throughout other zones of the aquifer system, as is characteristic of other karst aquifer systems. Anthropogenic groundwater declines in this regional karst aquifer system have been documented in published literature for decades, but the impacts of those declines in this coastal plain region and the embedded ecosystems that provide essential and critical habitat for native, endemic, and federally endangered and threatened species have not been considered previously. Those anthropogenic groundwater declines reduce surfacewater levels and flows due to the capture of both groundwater and overland flow of surfacewater, resulting in induced recharge through semi-confining zones and interbasin flow through fractures and other karst conduits. This case study identifies examples from the Greater Okefenokee Swamp Basin study area and comparison areas of how those declines result in loss of historic base flow to surface waters and other capture of surface waters, ultimately increasing saltwater intrusion. Those results alter and degrade the physical, chemical, and biological integrity of the nation’s waters, in violation of the US Clean Water Act (CWA) of 1972. Historic groundwater declines from mining and other anthropogenic groundwater withdrawals from this regional karst aquifer system already threaten the survival and recovery of federally endangered and threatened species, as well as existing and proposed critical habitat for those species within this regional extent, in violation of the Endangered Species Act (ESA) of 1973. This case study and its companion publication (Part 2) appear to be the first to provide scientific support for this regional karst aquifer system as the unifying factor in habitat responses to irreversible groundwater impacts on aquatic and marine ecosystems. These adverse impacts strongly suggest that the extent of the regional Floridan aquifer system should be designated as the Southeastern Coastal Plain Ecoregion for the purpose of managing natural resources. Mining activities continue to expand in our study area, which is the Greater Okefenokee Swamp Basin. Despite that fact, no comprehensive Areawide Environmental Impact Statement (AEIS), similar to the AEIS required for phosphate mining within the Central Florida Phosphate District (CFPD) approximately a decade ago has been conducted for any of the numerous mining projects that are occurring and are proposed within the Greater Okefenokee Swamp Basin. This case study also provides examples of why a comprehensive AEIS is essential to consider all of the adverse direct, indirect, and cumulative impacts of those mining activities to the CWA, the ESA, and the irreversible losses to local economies, because federal agencies responsible for considering those adverse impacts rely on public comments to identify those adverse impacts. The mining activities authorized throughout the regional Floridan aquifer system under Category 44 Nationwide Permits (NWP) result in the same type of adverse impacts as the mining activities evaluated under Individual Permits in that region. Therefore, those Category 44 NWP mining activities also should be required to obtain Individual Permits and be evaluated under an AEIS in the Greater Okefenokee Swamp Basin. This case study also describes how Florida’s assumption of the CWA Section 404 regulatory authority in 2020 severs four sub-basins within the Greater Okefenokee Swamp Basin study area at the state line between Florida and Georgia.展开更多

Little is known about obesity policy support in Canada, and substantial national variation in obesity policy support prevents direct transferability of these policies among nations. Our study recruited 521 young adults for an online survey through leaflets and flyers. We investigated how respondents’ demographics, health characteristics, political attitudes, beliefs regarding causes of obesity, and national identity affected their support for obesity policy. Results showed that there is high support for many obesity policies among Canadian young adults. Including Canadian national identity in regression models was significant in explaining obesity policy support beyond the combined effect of other predictors. Further exploration of national identity, in Canada and elsewhere, has implications for understanding obesity policy support that might assist policy makers in making more informed decisions in addressing obesity.展开更多

While Bangladesh has gained a degree of prominence in the world for its successful social forestry programs, the concept of collaborative pro- tected area management is rather new in the country, initiated in 2004 by the Bangladesh Forest Department in five PAs with financial assistance from USAID. Based on empirical evidence from three of the pilot PAs, we examined the achievements and associated challenges and prospects for co-management. Our fieldwork revealed a number of challenges faced by co-management institutions: (1) institutions were dominated by the elite group, overshadowing the voice of the community people; (2) mutual trust and collective performance are key to good governance but had not taken root in the PAs; (3) encroachment onto forest land and subsequent conversion to agriculture remained a serious problem that discouraged forest-dependent people from participating actively in co-management initiatives; (4) legal provisions (including acts, rules and policies) were not clearly and adequately disseminated and understood at the community level; (5) there remained a degree of ambiguity regarding the roles and responsibilities of forest department (FD) and co-management committees (CMC) in field operations, and this was not enhancing transparency and accountability of the overall initiative; (6) the long-term sustainability of co-management institutions was another major concern, as the local intuitional structure was still in a nascent stage, and provisioning of resources (either internally or externally) remained somewhat uncertain. We offer recommendations for improve- ment.展开更多

The results showed that arable land had been continuously decreased from 1996 to 2008, with a loss of 65.85× 10^3 hm2 and an average decrement of 5.49×10^3 hm^2 per year, and the loss in northern areas was larger; garden land and woodland were gradually centralized to the predominance area with an increment of 25.73×10^3 hm2 and 22.37×10^3 hm2, respectively; residential and industrial land increased year after year, and the transportation land showed the equalized developing spatial pattern; the increment of construction land and encroachment on arable land in the area were deeply influenced by the national macroscopic land-use policies, the rapid advance of urbanization and the development level of the regional economy. Through this case study, it is suggested that differential land- use policies should be adopted to create good environmental conditions to guarantee food security and to promote the economic development.展开更多

[Method]A total of 171 specimens of sinipercine were collected from Jinjiang River and its branches,identified and statistically counted.[Result]There were three species of wild sinipercine,including Siniperca scherzeri,Coreoperca whiteheadi and Siniperca kneri,with occurrence frequencies of100%,66. 7% and 50%,respectively. They were common species in the river,and S. scherzeri was dominant. The total allowable catch(TAC) of the three species was not big,and the individuals captured were generally small,and with rare mature individuals. [Conclusion]The resources of sinipercine had a preliminary recovery in the region after the foundation of the national resources protection area for aquatic resources in Jinjiang River in 2009.展开更多

文摘Russia’s invasion of Ukraine has significantly altered the pattern of alliances and geopolitical balances on the European continent to such an extent that countries like Finland and Sweden that have traditionally remained neutral are now applying to join the North Atlantic Treaty Organization(NATO).These two countries fear that Russia,which is currently trying to reposition itself,could try in the near future to invade these two Nordic countries to prevent the West(European Union,United Kingdom,and United States)from increasing its military presence and its military force in the Scandinavian peninsula and in the Baltic Sea.The enlargement that the European Union(EU)has carried out since the 1990s,and that has also meant the expansion of NATO,has been viewed with great concern by the government of Vladimir Putin,who considers that the United States and the European Union did not fulfill their commitment to former Russian President Mikhail Gorbachev to respect the sphere of influence of the former Union of Soviet Socialist Republics(USSR).Within the framework of this geopolitical confrontation,Helsinki and Stockholm do not want to run the risk of being invaded by the Russian army,which is why they seek to take advantage of the principle of collective security that NATO membership would grant them.

文摘National parks as protected areas have been on the spotlight because they are essential in achieving ecological civilization in China.Despite the profound achievements of national parks to conserve nature,the benefits of national parks for local residents remain lacking.Under the theory of harmonious coexistence between human and nature,this study focused on the development of local people’s livelihood in Qinghai’s national parks.We systematically explored the establishment of the national parks in Qinghai Province,analyzed the current prob-lems,and provided the main measures for developing people’s livelihood in protected areas in Qinghai.This study put forward the viewpoint that national parks should set a long-term goal,and gradually advance based on the environmental conditions and appropriately prioritize the improvement of local people’s wellbeing in the future.
文摘Interventions in Canada to address obesity have largely been limited to individual-level change through education rather than a population-level public policy approach. Little is known about obesity policy support in Canada, and substantial national variation in obesity policy support prevents direct transferability of these policies among nations. Our study recruited 521 young adults for an online survey through leaflets and flyers. We investigated how respondents’ demographics, health characteristics, political attitudes, beliefs regarding causes of obesity, and national identity affected their support for obesity policy. Results showed that there is high support for many obesity policies among Canadian young adults. Including Canadian national identity in regression models was significant in explaining obesity policy support beyond the combined effect of other predictors. Further exploration of national identity, in Canada and elsewhere, has implications for understanding obesity policy support that might assist policy makers in making more informed decisions in addressing obesity.
文摘Establishment of Protected Areas (PAs), in the face of rapid deforestation, forest degradation and climate change has been one of the key efforts in conservation of biodiversity worldwide in recent times. While Bangladesh has gained a degree of prominence in the world for its successful social forestry programs, the concept of collaborative pro- tected area management is rather new in the country, initiated in 2004 by the Bangladesh Forest Department in five PAs with financial assistance from USAID. Based on empirical evidence from three of the pilot PAs, we examined the achievements and associated challenges and prospects for co-management. Our fieldwork revealed a number of challenges faced by co-management institutions: (1) institutions were dominated by the elite group, overshadowing the voice of the community people; (2) mutual trust and collective performance are key to good governance but had not taken root in the PAs; (3) encroachment onto forest land and subsequent conversion to agriculture remained a serious problem that discouraged forest-dependent people from participating actively in co-management initiatives; (4) legal provisions (including acts, rules and policies) were not clearly and adequately disseminated and understood at the community level; (5) there remained a degree of ambiguity regarding the roles and responsibilities of forest department (FD) and co-management committees (CMC) in field operations, and this was not enhancing transparency and accountability of the overall initiative; (6) the long-term sustainability of co-management institutions was another major concern, as the local intuitional structure was still in a nascent stage, and provisioning of resources (either internally or externally) remained somewhat uncertain. We offer recommendations for improve- ment.
文摘Baiyangdian Technology Town initiated in 2015 is the pre -form of Xiong' an New Ar-ea which is both a national new area and a national special economic zone. Xiong' an New Areacan be regarded as an exploration of alternative mechanism of metropolitan space which fits the ruleof urban development. Xiong' an New Area is a national new area of the highest rank approved inthe process of National New Urbanization Plan. Therefore, the strategic positioning is supposed tobe fit in the new urbanization strategy and to have major leading and prototype functions in solvingthe problems of old style urbanization. Xiong' an New Area is to undertake great preas in preventingthe over gathering, which is a major task and principle of the planning.

文摘Based on land-use database updated with the survey of 1996, 2000, 2004 and 2008, this paper analyzed the land-use changes in the typical transect area along National Highway 106 with the aid of GIS technology and quantitative models. The results showed that arable land had been continuously decreased from 1996 to 2008, with a loss of 65.85× 10^3 hm2 and an average decrement of 5.49×10^3 hm^2 per year, and the loss in northern areas was larger; garden land and woodland were gradually centralized to the predominance area with an increment of 25.73×10^3 hm2 and 22.37×10^3 hm2, respectively; residential and industrial land increased year after year, and the transportation land showed the equalized developing spatial pattern; the increment of construction land and encroachment on arable land in the area were deeply influenced by the national macroscopic land-use policies, the rapid advance of urbanization and the development level of the regional economy. Through this case study, it is suggested that differential land- use policies should be adopted to create good environmental conditions to guarantee food security and to promote the economic development.

文摘[Objective]The paper was to provide a scientific basis for protection and utilization of sinipercine fish resources in Jinjiang River,the national resources protection area. [Method]A total of 171 specimens of sinipercine were collected from Jinjiang River and its branches,identified and statistically counted.[Result]There were three species of wild sinipercine,including Siniperca scherzeri,Coreoperca whiteheadi and Siniperca kneri,with occurrence frequencies of100%,66. 7% and 50%,respectively. They were common species in the river,and S. scherzeri was dominant. The total allowable catch(TAC) of the three species was not big,and the individuals captured were generally small,and with rare mature individuals. [Conclusion]The resources of sinipercine had a preliminary recovery in the region after the foundation of the national resources protection area for aquatic resources in Jinjiang River in 2009.
文摘China is a multi-ethnic country.From the wuzu gonghe ( Five nationalities under one u n io n ) in the early R epublic of China to the current union of 56 ethnic groups, the participation of ethnic m inorities in p o litica l affairs has always been a vita l and important factor for the development of China?s democratic politics. On one hand, the Nanjing National Government was dedicated to the model of a “ civil iden tificatio n ” and weakening ethnic characteristics.

文摘Land tenure security is pertinent to achieving the sustainable development agenda in cities where land is needed and useful for development purposes.Sufficient empirical research has been done to prove the importance of tenure security for investment,resilience,conservation,food security,as well as health and well-being,but it has not been clarified if and how land tenure security could adequately influence place loyalty and satisfaction with the residential environment,as it is clear that place loyalty and satisfaction are pertinent to inclusive development.Using the case of Ibadan City,the study examined how different dimensions of tenure security could determine residents’place loyalty and satisfaction.The study employed a survey cross-sectional research design to distribute 514 structured questionnaires to household heads across 4 sampled peri-urban local government areas while 452 were retrieved for analysis.Hierarchical regression analysis model was employed to understand the association between tenure security dimensions and satisfaction(as model I)and loyalty(as model II).For model I,F=8.640,P=0.000,R=0.555,and R^(2)=0.308 were obtained;while for model II,F=9.157,P=0.001,R=0.415,and R^(2)=0.173 were acquired.This thus means that residents’place loyalty and satisfaction can partly be explained by tenure security.In particular,respondents with no eviction experience,recognized property rights,and invulnerable to eviction have higher odds of being satisfied and loyal.Therefore,we recommend protection,improvement,and upgrading of land tenure security as one of the means to promote place loyalty and satisfaction,which is essential to achieving inclusive and sustainable development.
