This research analyses the Nile Fan wave energy forcasted from numerical modeling for 2020 of the Copernicus Marine Environment Monitoring Service (CMEMS) database, hourly sampled at 0.042° as the finest remotely-sensed data available. Wave power spatial distribution is analyzed using data from 259 points proposed as Wave Energy Converters (WECs). Spectral analyses techniques were appraised for disclosing the frequency and power return periods of the significant wave height and peak periods and to understand the similarity among selected WECs of varied conditions. K-means clustering was used to distinguish energy classes with large inter-class variances. The obtained wave power resources ( av . 5.32 kW/m; maximum of 112.9 kW/m; annual mean of 46.96 MW/m) are among the largest found in the Mediterranean Sea. More than 98 % of the wave power variance is controlled, in decreasing order of influence, by the depth, distance to shore, significant wave height, wave peak period, and the wave principal direction. Deepest water and near shore classes attained the largest wave power. Detailed environmental factors induced the wave shape and power is concluded.","PeriodicalId":320822,"journal":{"name":"Development Economics: Agriculture","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115420213","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}

Henan faces greater challenges in electricity revolution than other provinces. Currently, there are two development modes for generating low-carbon electricity in Henan: the ‘‘large-scale and long-distance transmission” (LSLDT) mode and the “local development and consumption” (LDC) mode. To make a better choice on development mode, following works have been done. Firstly, the rooftop PV installation potential is evaluated and two development scenes for wind and PV power generation are set to fit the development trend of Henan in the near future. Secondly, a bi-level generation planning model based on the total social cost is established. Finally, generation planning schemes are made and the power supply cost per kWh electricity is evaluated. It is found that there is a significant cost advantage when wind and PV electricity are generated with the LDC mode in both scenes. What’s more, the existence of reliability cost, wheeling cost and grid-loss cost makes the LSLDT mode difficult to cut down the wind and PV power supply cost. Wind and PV power generation of the LDC mode should be focused on in Henan.","PeriodicalId":320822,"journal":{"name":"Development Economics: Agriculture","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122987255","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}

Ryan","doi":"10.2139/ssrn.3861350","DOIUrl":"https://doi.org/10.2139/ssrn.3861350","url":null,"abstract":"We challenge the narrative that climate change transition risk is not being priced into sovereign bond markets. As measured by carbon dioxide emissions, natural resources rents and renewable energy consumption, climate change transition risk is factored into sovereign bond yields (and spreads) by investors. Using a sample of data from 23 advanced and 16 developing markets from 2000-2019, we show that countries with lower carbon emissions incur a lower risk premium on sovereign borrowing costs. Moreover, advanced countries willing to reduce their earnings from natural resources rents and, to some extent, increase renewable energy consumption are associated with lower sovereign borrowing costs. In contrast, developing countries with a strong dependence on natural resources or restricted renewable energy consumption incur lower sovereign borrowing costs. Thus, advanced economies that perform poorly in managing their climate transition may encounter increased sovereign borrowing costs, liquidity constraints, reduced capacity to effectively manage climate transition and the inability to finance economic recovery from severe climate shocks or natural disasters. The necessity to support developing countries to meet climate change targets also emerges. Given the threat climate change poses to the global economy and the fact that transition risk is materialized much faster than physical risk, we advocate an increase in the significance of climate transition risk factors as determinants of sovereign bond markets.","PeriodicalId":320822,"journal":{"name":"Development Economics: Agriculture","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121410888","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}

This study used a descriptive-quantitative correlation design. A total of 3 key informants and 90 farm families head composed of the respondents. A survey questionnaire was prepared as an instrument in gathering the required information. The mean of 51.69 years old signifies that most of the respondents' ages were at the prime working age. A majority (95.70%) of the households were headed by male farmers and have no other source of income other than farming. Concrete roads were constructed as early as 2013 and 2018 in the area of study. Only a few jobs were created that are related to roads constructions The adoption of technology for rice production does not change after the development of infrastructure. The same goes with the adoption of technology for vegetable production which yielded ‘often’ responses in all items in the first and second cropping. After the development of the infrastructure, farm inputs investment decreases in comparison with first and second cropping. A noticeable increase in net income was noticed from first to second cropping. After the development of infrastructure, those who opted to plant Inbred/Hybrid variety decreases. On the other hand, the majority of the respondents opted not to plant vegetables. The development of the infrastructure has no effects on the cropping pattern of the respondents. In terms of the production level, there was an increase in the yield of the respondents before and after the development of the infrastructure.","PeriodicalId":320822,"journal":{"name":"Development Economics: Agriculture","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115522528","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}
