Research on Water Resources Conservation of Mountain River Based on the Concept of Region Partition

Presently concepts and methods related to water resources conservation of mountain rivers are seriously insufficient,and its level is far from being adaptable to the development of a harmonious society.As mountain ecosystems play a key role in water resources conservation of mountain rivers,and the characteristics of mountain ecosystems and hydrologic features of mountain river follow strong temporal and spatial distribution,partition theory can be applied to the water resources conservation of mountain river.This theory observes the following partition principles:regional relativity,spatial continuity,integralcounty,meeting management needs,hierarchical principle,and comparability principle.And it lays equal emphasis on both water resources conservation and environmental protection,on both water quality conservation and water quantity protection,on the combination of water features,water cycle and water pollution.In the partition methods,index method and map superposition method will be applied in region partition.The example of region partition of water resources conservation in the upper reaches of the Yangtze River shows that the partition theory is practicable in water resources conservation of mountain rivers,and it provides a platform for future study in water resources conservation.

Local People＇s Perception of Forest Resources Conservation in Ekiti State, Nigeria

This study examines local people＇s perception of forest resources （FR） conservation around two plantation forest reserves （PFR） and two natural forest reserves （NFR） in Ekiti State in order to determine the factors that can contribute to sustainable FR conservation. Questionnaire and interview were used to collect data from 240 respondents. Data were analyzed using descriptive and inferential statistics. 75.0% and 86.1% of respondents around PFR recognized the importance of conserving the FR for economic benefits and biodiversity respectively, while 66.7% would not want the FR conserved for cultural values. 82.9% of respondents around NFR would want the FR conserved for economic benefits, while 74.3% and 66.7% would not want the forest conserved for cultural values and biodiversity respectively. For efficient conservation, participation in forest management and involvement in decision making with means of 3.45 and 3.52 ranked highest in PFR and NFR respectively. Probit regression analysis showed that in PFR and NFR, age, education and income were positively significant to FR conservation （p 〈 0.05）. Creating an enabling environment that will make local people appreciate historical cultural values of the forest for tourism is essential for efficient FR conservation in the study area.

Saving Resources for Future Demands-The Role of Instruction,Cognitive Load and Metacognition

Two studies test the hypothesis of conserving resources while performing depleting physical tasks and the modifying role of metacognitive self(MCS).A total of 216 undergraduate students performed two types of physical tasks(a body support on forearms―the first experiment;and a cold water test―the second experiment)in anticipation vs.no anticipation of the future task conditions.Among individuals with high-MCS much weaker persistence could be observed than among those with low-MCS.These results support theories of adaptive goal disengagement suggesting that how individuals apply their resources may stem from other reasons than ego depletion.

The Role of Sports Diplomacy in Advancing Environmental Security in Africa: Case of Forest Conservation in Kenya

Environmental security remains a key challenge in the late 19th through to the 21st century,whose solution has attracted a number of initiatives.Sports diplomacy has achieved great strides in achieving international,regional,and local unity.However,the use of sports diplomacy in achieving environmental security has received much less research attention.This research examines the role of sports in diplomacy in achieving environmental security in Kenya.This study was anchored on the soft power theory and Conservation of Resources(COR)theory which offer frameworks for explaining the role of sports diplomacy in advancing environmental security.The study adopted exploratory research design.The target population was diplomats,marathoners,coaches,environmentalists,conservationists and government officials,academia as well as Water Resources Authority(WRA).The primary data were obtained through open and closed structured questionnaire.The collected data were analyzed through the use of frequency distribution,and thematic analysis.The study established that sports diplomacy advanced environmental security in Kenya,which was better for athletics and volleyball.Environmental security was also enhanced through training,sensitization,conservation efforts,and environmental education.Sport events also allowed a contact-platform for interaction between various groups involved in environment and forest conservation.This study recommends that sports diplomacy should be used in most of the regions in Kenya experiencing environmental perturbations and the current strategies should be applied in the sports diplomacy and environmental conservation as well as security.Further,the government is also encouraged to appoint more sports ambassadors with proper environmental knowledge to help in environmental management.The role of academicians in sports diplomacy and environmental security was found to be minimal where academicians should be at the forefront as the 21st century diplomats are incorporated into sports to be local ambassadors.Perceiving the significance of sports diplomacy and environmental security,there is need for coordination between various county governments to coordinate their efforts and in the process they should bring on board even the non sports actors to boost the role of sports in diplomacy and environment.
