“…The studies availability on economic and financial profitability has been strongly concentrated in Middle East, South Africa and India: 10 focused on Tanzania, 5 in Kenya, 3 in Mozambique and 6 in India (18). Wishkerke et al (23) calculated the NPV of different production systems of Piñón, giving a profitability figures between -10.000 a 9.500 USD$ ha -1 in Tanzania, Wang et al (24) estimated around 2.000 USD$ ha -1 in China, while Basili y Fontini (25) found 56.000 -dos M$ ha -1 (using different interest rates). The assumptions of these studies fluctuate to such a degree that is not possible to make a direct comparison with the results of this research.…”

Objetivo. Evaluar la viabilidad económica y financiera de los sistemas silvopastoriles tradicionales para la producción de Biocombustibles como aporte a la sostenibilidad del proyecto “Piñón para Galápagos”. Materiales y Métodos. Se llevaron a cabo encuestas a 450 pequeños productores ganaderos de 10 cantones de la provincia de Manabí con la finalidad de colectar información agronómica, manejo, costos implicados en establecimiento y producción de los sistemas silvopastoriles vigentes de Piñón (Jatropha curcas L.)/Saboya (Megathyrsus maximus). Para recopilar datos de producción del Piñón establecido en cercas vivas de Piñón INIAP CP041 e igualmente se registró la producción de sistemas en 10 sitios, desde el año 2009. Con estos datos se calcularon los siguientes indicadores financieros radio beneficio/costo (B/C), valor actual neto (VAN), tasa interna de retorno (TIR) y valor de expectativa de la tierra (VET). Resultados. El estudio mostró una disminución de la producción del Piñón con el transcurso del tiempo. El sistema silvopastoril mejorado con Piñón INIAP CP041 mostró B/C 1.07, VAN de USD$ 404.11, VET USD$ 970.23 y TIR de 18%. Seguido del sistema silvopastoril con Piñón local con un B/C 1.06, VAN de USD$ 363.66, VET USD$ 873.10 y TIR de 17% y finalmente sistema silvopastoril sin cosecha del Piñón con un B/C 1.05, VAN de USD$ 285.72, VET USD$ 685.99 y TIR de 15%. Conclusiones. La alternativa de producción de biocombustibles con sistemas silvopastoriles Piñón (INIAP CP041)/Saboya en Manabí es el sistema de mayor rentabilidad y no competiría por superficies de cultivo para la producción de alimentos, sin afectar a la seguridad alimentaria.

“…Woodlot plantations were often not well adapted to the local situation and failures emanated from the use of inappropriate tree species or the selection of inappropriate sites [11]. Even when woodlot plantations were productive, the costs for land, labor and transport were not compensated for by the revenues from fuelwood sales and the plantations were unprofitable [141].…”

Increasing the sustainability of household cooking in developing countries: Policy implications

Although 40% of the global population relies on traditional biomass use, mainly firewood and charcoal, for cooking, traditional biomass has received very little attention in the current biomass debate, because of its considered primitive and unsustainable nature. In this review, we discuss how the sustainability of household cooking in developing countries can be improved.Indoor air pollution due to incomplete combustion of traditional biomass causes the death of 1.45 million people every year, mainly of women and children, who also carry the heavy burden of fuelwood collection. In addition, charcoal production and combustion is responsible for very high greenhouse gas emissions per unit of energy. On the other hand, fuelwood production and trade is of vital importance for local economies and serves as safety net for the poorest people. Moreover, fuelwood collection is not a driver of deforestation and global fuelwood shortage will not occur, despite local problems of fuelwood provision.There are two distinct policy alternatives to increase the sustainability of cooking in developing countries. The first option is to climb the energy ladder and to switch from solid fuels to fossil fuels (LPG or kerosene), biogas or electricity. As this largely avoids the severe health damages of traditional biomass use, this option is considered the most desirable by numerous countries and by international organizations. However, as most developing countries are far away from meeting the necessary requirements, related to infrastructure, economics and local culture, expecting a large-scale switch to liquid fuels or electricity is unrealistic.In that case, the second policy option, increasing the sustainability of the current traditional biomass system, must be considered. This can be realized by an integrated approach, in which national and regional fuelwood policies are adapted, improved systems for charcoal production are implied and improved stoves, in combination with chimneys, are distributed.

Summary Levelized cost of energy (LCOE) method is a frequently used approach to determine the economics of an energy project. However, the approach have faced a lot of criticism due to the lack of transparency in costing along with some additional drawbacks. Although the refinement of the LCOE method has led to its improvement, but there are still some concerns in the form of considerable benefits that may produce unreliable results. In order to provide the solution of drawbacks associated with LCOE method, this research work focuses on presenting an alternative costing approach. The adoption of benefit‐to‐cost ratio analysis (BCRA) method for the decision‐making of energy systems is proposed in this work. A comprehensive assessment between LCOE and BCRA methods was carried out with a purpose to observe their influence in determining the success or failure rate of an energy project by considering the associated benefits. For this purpose, two case studies were considered; Chena Geothermal Power Plant (Alaska, United States) and Quaid‐e‐Azam Solar Power Project (Bahawalpur, Pakistan). The assessment was carried out on the basis of different scenarios, which were developed according to the obtainable benefits from a particular project. The results show that, compared with the LCOE method, the BCRA method is more feasible and practical in energy project decision‐making process. Moreover, it was noticed that the BCRA method can provide better and useful insights to help maximize the economic benefits of the project.
