In this paper, we provide models for analyzing the impact of the interdependencies between a core electricity market and its neighboring markets on key long-run decisions. This we do both for zonal and nodal pricing schemes. The identification of welfare optimal investments in transmission lines and renewable capacity within a core electricity market requires a spatially restricted objective function, which also accounts for benefits from cross-border electricity trading. This leads to mixed-integer nonlinear multilevel optimization problems with bilinear nonconvexities for which we adapt a Benders-like decomposition approach from the literature. In a case study, we use a stylized six-node network to disentangle different effects of optimal regional (as compared to supra-regional) investment planning. Regional planning alters investment in transmission and renewable capacity in the core region, which affects private investment in generation capacity also in adjacent regions and increases welfare in the core region at the cost of system welfare. Depending on the congestion-pricing scheme, the regulator of the core region follows different strategies to increase welfare causing distributional effects among stakeholders.","PeriodicalId":101533,"journal":{"name":"ERN: Exploitation of Renewable & Non-Renewables Natural Resources & the Environment (Topic)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128243519","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}

We evaluate the direct effect of resources on developmental outcomes vis-a-vis their indirect effect through the weakening of political institutions using a 3SLS instrumental variable setup that simultaneously estimates development outcomes and institutions. We find that resource abundance and resource dependence affect development outcomes through different channels. While resource abundance generally has a direct positive effect on developmental outcomes, resource dependence has a stronger negative indirect effect that operates through its negative impact on institutional quality. The results also depend on the type of development outcome considered, with more consistent positive direct effects found for physical capital measures and stronger negative indirect effects for human capital development. The use of a simultaneous framework and dual measures of resources reconciles seemingly contradictory findings in earlier work.","PeriodicalId":101533,"journal":{"name":"ERN: Exploitation of Renewable & Non-Renewables Natural Resources & the Environment (Topic)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116805246","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 need for subsidy is fading as the cost of electricity from renewables converges with that from fossil fuels, but the withdrawal of support schemes will also remove the revenue stability offered by auction schemes and contracts for differences. Exposure to market risk (fluctuating wholesale electricity prices) raises the cost of capital for merchant renewable generators. Here we quantify the extent to which increased volatility in future power prices affects revenues by combining electricity market and stochastic discounted cash flow models. Renewable projects relying purely on merchant pricing may see cost of capital rise by two percentage points (e.g. from 7% to 9%). Unless new private or government actors provide hedging solutions, fewer developers will undertake new renewable energy projects, slowing the energy transition and increasing its cost to society.","PeriodicalId":101533,"journal":{"name":"ERN: Exploitation of Renewable & Non-Renewables Natural Resources & the Environment (Topic)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117138961","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}

Its special focus is to investigate the impact of Global Memorandum of Understandings (GMOUs) on rural young people involved in non-timber forest products (NTFPs) for sustainable livelihood in Niger Delta, Nigeria.\u0000\u0000\u0000Design/methodology/approach\u0000Data for this study were collected from primary sources, using participatory rural appraisal technique of semi-structured interview questionnaire. The use of participatory research techniques in collecting CSR impact data especially as it concerns the rural young people is because it involves the people being studied, and their views on all the issues are paramount. Both descriptive and inferential statistics were used to analyse the data. Inferential statistical tool – estimation of logit model was used to test the two research hypothesis.\u0000\u0000\u0000Findings\u0000The results indicate that GMoUs have not given adequate attention to young people as a special target sub-group who live in rural areas and depend mostly on NTFPs. Results also show that a number of factors hindering rural young people from the use and development of NTFPs include a policy vacuum, non-destructive harvesting, and destruction of natural habitats, bushfires, population growths and high demands.\u0000\u0000\u0000Research limitations/implications\u0000The semi-structured interview questionnaire was directly administered by the researchers with the help of research assistants. The use of local research assistants was because of the inability of the researchers to speak the different local languages and dialects of the many ethnic groups of Ijaws, Ogonis, Ikweres, Etches, Ekpeyes, Ogbas, Engennes, Obolos, Isokos, Nembes, Okirikas, Kalabaris, Urhobos, Iteskiris, Igbos, Ika-Igbos, Ndonis, Orons, Ibenos, Yorubas, Ibibios, Anangs, Efiks, Bekwarras, Binis, Eshans, Etsakos, Owans, Itigidis, Epies, Akokoedos, Yakkurs, etc., in the sampled rural communities.\u0000\u0000\u0000Practical implications\u0000An appropriate GMoU-intervention framework for sustainable promotion of NTFPs, domestication of NFTPs, improving harvesting and processing techniques are necessary to facilitate good security, reduction of poverty and improved livelihoods, particularly for the economically-marginalized and forest-dependent rural young people is imperative.\u0000\u0000\u0000Social implications\u0000Sustainable livelihoods of the forest-dependent rural young people in sub-Saharan Africa would require some focussed CSR interventions on the NTFPs for sustainable livelihood. Facilities pertaining to storage, grading, processing and value addition through the convergence of existing schemes and programmes should be promoted and created. MOCs are in a position to empower the rural young people with information about the market, policy and products to enable the rural people strategizing and accessing returns from NTFPs in sub-Saharan Africa.\u0000\u0000\u0000Originality/value\u0000This research adds t","PeriodicalId":101533,"journal":{"name":"ERN: Exploitation of Renewable & Non-Renewables Natural Resources & the Environment (Topic)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121327140","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}

We consider trade specialisation in natural resources, high and low tech manufacturing and business services, before and after the financial crisis. The aimed contribution of this paper is to shed light on the effects of trade specialisation as measured in domestic value added embodied in exports rather than gross exports. We add to the literature on GVCs by: (i) studying the role of the domestic productive structure in countries’ trade specialisation and performance, (ii) accounting for the rate of changes in trade specialisation as affecting GVC performance. We employ Balassa indexes based on value added flows in a GMM dynamic panel framework. We find that trade specialisation in low-tech manufacturing and natural resources have a negative impact on value added exported by countries. High-tech manufacturing and knowledge intensive services exhibit a positive effect during the crisis period. We discuss these findings in relation to the recent debates on the role of manufacturing and premature de-industrialisation in developing countries.","PeriodicalId":101533,"journal":{"name":"ERN: Exploitation of Renewable & Non-Renewables Natural Resources & the Environment (Topic)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115166232","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}

In 2000, Brazilian pixels were 30 percent more likely to be deforested, and between 2001 and 2005 annual Brazilian deforestation was more than 3 times the rate observed across the border. In 2006, just after Brazil introduces policies to reduce illegal deforestation, these differences disappear.

Controlling deforestation is difficult, especially because there are 484 million of hectares of forest that are community owned.

We study the effect of communal titling on deforestation in Colombia, using a difference-in-differences strategy at the border. We find that deforestation decreased only in small communal titles, even when the control area are national parks. This suggests that communal titling can be effective on reducing deforestation if inhabitants can monitor the area titled.","PeriodicalId":101533,"journal":{"name":"ERN: Exploitation of Renewable & Non-Renewables Natural Resources & the Environment (Topic)","volume":"222 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114586531","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}

Los objetivos principales de un Plan de Seguridad del Agua (PSA) son: la minimización de la contaminación de las fuentes de agua, la reducción o eliminación de la contaminación a través de procesos de tratamiento adecuados, y la prevención de la contaminación durante el procesamiento, distribución y almacenamiento. En este sentido, se presenta el diseño del Plan de Seguridad del Agua (PSA) para el sistema de abastecimiento de agua potable del municipio de Tocaima, ubicado en el departamento de Cundinamarca. El PSA para la empresa INGEAGUA S.A.S. E.S.P., se evalúa con criterios puntuales basados en el Manual para el Desarrollo de Planes de Seguridad del Agua de la Organización Mundial de la Salud; después de dicho estudio se presentan las medidas de control a tomar ante los riesgos y peligros encontrados y posteriormente se define cómo podría reaccionar al implementar tales medidas. En el análisis efectuado se identificaron riesgos significativos hacia la calidad, cantidad y continuidad en el servicio. En primer lugar, la fuente de abastecimiento está afectada por actividad agrícola y vertimientos de aguas residuales. La captación está ubicada en una zona de fácil acceso a turistas y la rejilla no cumple con su función, pues en las épocas más secas, el caudal es mínimo y la captación se hace por debajo del mínimo necesario. En cuanto a tratamiento la planta está diseñada para trabajar con tres floculadores mecánicos de paleta pero sólo uno de ellos funciona correctamente; otro está fuera de servicio y el tercero fue retirado. La desinfección no se realiza correctamente pues el cloro ingresa directamente al tanque sin pasar por un proceso de mezcla que garantice que el porcentaje de cloro residual es el indicado. La metodología empleada es la propuesta por la Organización Mundial de la Salud (OMS), la cual entrega una serie de parámetros a seguir a la hora de elaborar y ejecutar un plan de seguridad del agua (PSA). Está compuesto de 5 fases de preparación, evaluación del sistema, monitoreo operativo, gestión y comunicación, retroalimentación y mejora del sistema, que a su vez, están divididos en 11 módulos.
