Running a risk of an oil shortage in the near term, Egypt's strategic energy policy should shift from oil towards multiple energy sources including natural gas, oil, and alternative energy uses. The approach applied to Egypt's energy resources is based on optimal resource extraction rates (Hartwick's model) whereby dynamic efficient production schedules, conditional on the constraint of sustainable growth rates in consumption, dictate future energy requirements. Detailed strategies for Egypt's energy sector are proposed, accompanied by their expected impacts on the economy: (1) a sustainable production path for oil and natural gas as strategic energy resources until 2025, (2) reduction and ultimate removal of energy subsidies by 2017 with oil subsidy removal by 2010, (3) required investments for energy self-sufficiency estimated at $120 billion over ten years for natural gas and 5.25% annual investment growth for oil through 2020, and (4) timeline adoption of alternative energy sources including solar and nuclear energy to substitute oil with 10% alternative energy use by 2015 and 25% by 2025.","PeriodicalId":101533,"journal":{"name":"ERN: Exploitation of Renewable & Non-Renewables Natural Resources & the Environment (Topic)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131807041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Watershed Development Programme has three important features: Unprecedented devolution of decision-making power backed up by financial allocation directly to the district level and hence to the village organisation level, creation of partnerships between government and non-government organisations, and technical and financial flexibility. The project places special emphasis on improving the economic and social conditions of the poor and the disadvantaged sections of the watershed community. This has to be achieved through equitable distribution of benefits from land and water resources and through greater access to income-generating opportunities. With this background the present paper attempts to evaluate two different watershed development programmes in India under different management regimes. Considering both the project implementing agencies (PIA) and their performances this study summarizes that in few cases (total cultivated area, irrigated area and cropping intensity) the Government agency has resulted better than that of the voluntary organisations. as the PIA. But when we consider the participation of the beneficiaries, the voluntary organisations has yielded better result. The evaluation suggests that the WDA will bring sustainable development and will more successful when both the PIAs (Government & the Voluntary organisations) will work together at the village level.","PeriodicalId":101533,"journal":{"name":"ERN: Exploitation of Renewable & Non-Renewables Natural Resources & the Environment (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125235942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For economies whose development is not exogenously and directly affected by time (i.e., time-autonomous economies), this stationarity condition generalizes Dixit et al.'s (1980 ) \"zero-net-aggregate-investment\" rule of sustain-ability, which in turn generalizes Solow-Hartwick's sustainability rule. For non-autonomous economies, the stationarity condition is not generally fulfilled, and the current-value Hamiltonian under (over) estimates the true welfare level by an amount equal to the discounted value of the net \"pure time effect.\" For the non-autonomous case of a time-dependent utility discount rate, a general condition on the discount rate function (of which the hyperbolic discount rate function is a special case) upholds the results obtained for autonomous cases. The paper concludes with a discussion of policies that promote both optimality and sustainability objectives.

In order to systematically evaluate the international competitiveness of renewable energy products of these countries, the current study has built a new multi-dimensional evaluation index to estimate the international competitive edge of renewable energy products exported from these countries, by abandoning the traditional methods for measuring trade competitiveness and adopting the projection pursuit (PP), TOPSIS model and the improved weighting methodology. The results demonstrate that the overall international competitiveness of renewable energy products from the BRI countries is weak, with dramatic differences in different countries in the evolution trends; the factors influencing the international competitiveness in the BRI countries are significantly different and; China's renewable energy products are competitive, and their competitiveness is growing rapidly in the past decade. Finally, this study has put forward corresponding policy implications.","PeriodicalId":101533,"journal":{"name":"ERN: Exploitation of Renewable & Non-Renewables Natural Resources & the Environment (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128690111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
