Sustainable bioenergy production strategies for rural India

The paper aims to assess the potential of decentralized bioenergy technologies in meeting rural energy needs and reducing carbon dioxide (CO2) emissions. Decentralized energy planning is carried out for the year 2005 and 2020. Decentralized energy planning model using goal programming technique is applied for different decentralized scales (village to a district) for obtaining the optimal mix of energy resources and technologies. Results show that it is possible to meet the energy requirements of all the services that are necessary to promote development and improve the quality of life in rural areas from village to district scale, by utilizing the locally available energy resources such as cattle dung, leaf litter and woody biomass feedstock from bioenergy plantation on wastelands. The decentralized energy planning model shows that biomass feedstock required at village to district level can even be obtained from biomass conserved by shifting to biogas for cooking. Under sustainable development scenario, the decentralized energy planning model shows that there is negligible emission of CO2, oxide of Sulphur (SOx) and oxide of nitrogen (NOx), even while meeting all the energy needs.

Dynamics of rural energy access in India: An assessment

India's rural energy challenges are formidable with the presence of majority energy poor. In 2005, out of a rural population of 809 million, 364 million lacked access to electricity and 726 million to modern cooking fuels. This indicates low effectiveness of government policies and programs of the past, and need for a more effective approach to bridge this gap. However, before the government can address this challenge, it is essential that it gain a deeper insight into prevailing status of energy access and reasons for such outcomes. Toward this, we perform a critical analysis of the dynamics of energy access status with respect to time, income and regions, and present the results as possible indicators of effectiveness of policies/programmes. Results indicate that energy deprivations are highest for poorest households with 93% depending on biomass for cooking and 62% lacking access to electricity. The annual growth rates in expansion in energy access are gradually declining from double digit growth rates experienced 10 years back to just around 4% in recent years. Regional variations indicate, on an average, cooking access levels were 5.3 times higher in top five states compared to bottom five states whereas this ratio was 3.4 for electricity access.

Modern energy access to all in rural India: An integrated implementation strategy

Expanding energy access to the rural population of India presents a critical challenge for its government. The presence of 364 million people without access to electricity and 726 million who rely on biomass for cooking indicate both the failure of past policies and programs, and the need for a radical redesign of the current system. We propose an integrated implementation framework with recommendations for adopting business principles with innovative institutional, regulatory, financing and delivery mechanisms. The framework entails establishment of rural energy access authorities and energy access funds, both at the national and regional levels, to be empowered with enabling regulatory policies, capital resources and the support of multi-stakeholder partnership. These institutions are expected to design, lead, manage and monitor the rural energy interventions. At the other end, trained entrepreneurs would be expected to establish bioenergy-based micro-enterprises that will produce and distribute energy carriers to rural households at an affordable cost. The ESCOs will function as intermediaries between these enterprises and the international carbon market both in aggregating carbon credits and in trading them under CDM. If implemented, such a program could address the challenges of rural energy empowerment by creating access to modern energy carriers and climate change mitigation. (C) 2011 Elsevier Ltd.

Achieving universal rural energy access in india: A low carbon pathway

India's energy challenges are three pronged: presence of majority energy poor lacking access to modern energy; need for expanding energy system to bridge this access gap as well as to meet the requirements of fast-growing economy; and the desire to partner with global economies in mitigating the threat of climate change. The presence of 364 million people without access to electricity and 726 million relying on biomass for cooking out of a total rural population of 809 million indicate the seriousness of challenge. In this paper, we discuss an innovative approach to address this challenge, which intends to take advantage of recent global developments and untapped capabilities possessed by India. Intention is to use climate change mitigation imperative as a stimulus and adopt a public-private-partnership-driven ‘business model' with innovative institutional, regulatory, financing, and delivery mechanisms. Some of the innovations are: creation of rural energy access authorities within the government system as leadership institutions; establishment of energy access funds to enable transitions from the regime of "investment/fuel subsidies" to "incentive-linked" delivery of energy services; integration of business principles to facilitate affordable and equitable energy sales and carbon trade; and treatment of entrepreneurs as implementation targets. This proposal targets 100% access to modern energy carriers by 2030 through a judicious mix of conventional and biomass energy systems with an investment of US$35 billion over 20 years. The estimated annual cost of universal energy access is about US$9 billion for a GHG mitigation potential of 213Tg CO2e at an abatement cost of US$41/tCO2e. It is a win-win situation for all stakeholders. Households benefit from modern energy carriers at affordable cost; entrepreneurs run profitable energy enterprises; carbon markets have access to CERs; the government has the satisfaction of securing energy access to rural people; and globally, there is a benefit of climate change mitigation.

La legítima sucesoria y la atomización de la propiedad rural en la Argentina

Resumen: La propiedad rural en la Argentina ha sufrido un proceso de pulverización ocasionado fundamentalmente por dos fenómenos: la venta de tierras y la división forzosa hereditaria. La excesiva subdivisión de la propiedad generada por las leyes sucesorias modernas ha sido no solo constatada por estudios recientes sino también, más atrás en el tiempo, por el propio autor de esas disposiciones legales, es decir, por Vélez Sársfield. Acercándonos a los ciento cuenta años de la vigencia del Código Civil argentino, se observa en la realidad que la aplicación del sistema sucesorio inalterado por este gran lapso ha conducido a una paulatina desaparición de la mediana propiedad rural y, como contrapartida, a la marcada aparición del minifundio y del latifundio. El autor menciona algunas reformas al Código Civil y algunos institutos creados con posterioridad a su sanción, como la unidad económica, que desafortunadamente no han detenido el proceso de atomización de la propiedad agraria y propone, en cambio, otros que podrían mejorar la situación presente, entre ellos, el aumento de la porción disponible por testamento cuya tendencia se advierte en el derecho comparado. La familia agropecuaria requiere de una propiedad estable con dimensiones suficientes para su sustento y para continuar poblando nuestro inmenso territorio.

Turismo rural como estrategia de diversificación: factores determinantes y resultados en Galicia

[ES] Los determinantes y los resultados de la estrategia de diversificación se han abordado frecuentemente en la literatura. Son sin embargo pocos los estudios que analizan la diversificación en sectores concretos donde el impulso para diversificar no es estrictamente económico, sino político o social. La diversificación de la actividad agrícola hacia el turismo en Galicia es un claro ejemplo de este fenómeno. El objetivo de este trabajo es determinar cuales son los factores que motivan a titulares de explotaciones agrarias gallegas a iniciar una estrategia de diversificación hacia el turismo, así como las dimensiones de los resultados empresariales relevantes para dichos propietarios. Los resultados del análisis sobre una muestra representativa de los establecimientos de turismo rural de Galicia indican la multidimensionalidad y heterogeneidad de los constructos analizados. Las motivaciones sociales adquieren gran protagonismo, del mismo modo que las medidas subjetivas de resultado empresarial relacionadas con la mejora del entorno y la orientación al cliente.

Ultimately, the project is aimed at increasing the productivity of fishermen/fish farmers and hastening the development of rural communities

Estudar à noite e trabalhar de dia: desafios de quem deseja prosseguir com os estudos no Instituto Multidisciplinar da Universidade Federal Rural do Rio de Janeiro em Nova Iguaçu.

É urgente a necessidade da maior inclusão social dos estudantes que articulam a rotina de trabalho diurno e a educação formal noturna, objetivando melhorar as condições de vida através de aumentar oportunidades no mercado de trabalho. Por ser tema de extrema relevância social, a presente pesquisa busca compreender os desafios de alunos matriculados em cursos de Ensino Superior noturno no Instituto Multidisciplinar da Universidade Federal Rural do Rio de Janeiro, destacando o processo de democratização do acesso e a permanência de jovens de camadas populares em quatro cursos de graduação. Descrevemos políticas públicas de acesso e de permanência dos estudantes nos cursos superiores noturnos de Pedagogia, História, Matemática e Administração, tendo em vista contribuir com a discussão da real efetividade destes cursos para a democratização da educação superior. O procedimento metodológico é a investigação qualitativa em estudo de caso. Nesta pesquisa, foram contatadas pessoas chave da universidade, aplicados 361 questionários e entrevistados 39 alunos de quatro cursos escolhidos. Os resultados relacionados aos fatores sociais que impõem o caráter compulsório do trabalho ao estudante universitário confirmaram que o jovem, dos cursos noturnos estudados deste Instituto Multidisciplinar, em geral, tem dificuldades de gerenciar sua vida para contemplar as diversas demandas, isto é, as sociais, familiares, educacionais e laborais. O jovem estudado costuma ter um perfil de vulnerabilidade socioeconômica. Os resultados também mostram em alguns discursos dos entrevistados alguns desafios de conciliar o curso noturno com a vida de trabalho. Assim, os resultados também revelam a necessidade de que mais recursos sejam destinados a programas com alunos com o perfil de vulnerabilidade socioeconômica. Apesar do perfil heterogêneo dos alunos desta pesquisa, os resultados apontam também que muitos aproveitam a oportunidade de continuidade de escolarização conciliando o trabalho diurno com a educação noturna. A opção destes por cursos de licenciaturas, como os de Matemática, História e Pedagogia, é atrativa pela maior facilidade de acesso devido a serem carreiras menos disputadas no ingresso à universidade pública. Embora a profissão docente em nossa sociedade não ofereça elevado prestígio social, ter a formação e o diploma de Ensino Superior ainda é para muitos jovens, uma possível trajetória que pode levar a mobilidade social. Assim, as políticas públicas precisam melhor atender os jovens deste segmento populacional que deseja estudar e trabalhar com educação.

Studies on the performance of Ovatide on breeding of Indian major carps

The paper deals with the experimental studies on breeding of Indian Major Carps - Catla catla (Valenciennes), Labeo rohita (Hamilton), Cirrhinus mrigala (Hamilton), & Labeo calbasu (Hamilton) with the help of 'Ovatide' which is being used as an alternative inducing agent for commercial seed production. This study has been conducted for six consecutive months (April - September, 2000) in a stone-pitched breeding channels of a farm located at Midnapore District, West Bengal. The doses of 'Ovatide' (0.5 ml/kg of fish weight) remained same for each female species during the entire study period and males were released without any dose. The physicochemical parameters of water during different months were estimated. The latency period and fertilization percentage varied in different months and species. The results confirmed that 'Ovatide' can be used successfully in a much more cost-effective way for induced breeding of carps, even in rural fish farms with morrum-pitched breeding channels.

Water budgeting studies on the hatchery and nursery rearing practices for the common carp, Cyprinus carpio (Linnaeus, 1758)

Aquaculture systems are an integral element of rural development and therefore should be environment friendly as well as socially and economically designed. From the economic standpoint, one of the major constraints for the development of sustainable aquaculture includes externalities generated by competition in access to a limited resource. This study was conducted as an investigation into the water requirement for the hatchery and nursery production phases of common carp, Cyprinus carpio (Linnaeus, 1758) at the Maharashtra State Fish Seed Farm at Khopoli in Raigad Dist. of Maharashtra during the winter months from November to February. The water budgeting study involves the quantification of water used in every stage of production in hatchery and nursery systems and aimed at becoming a foundation for the minimization of water during production without affecting the yield; thereby conserving water and upholding the theme of sustainable aquaculture. The total water used in a single operation cycle was estimated to be 11,25,040 L [sic]. Out of the total water consumed, 4.74% water was used in the pre-operational management steps, 4.48% was consumed during breeding, 62.72% was consumed in the hatching phase, 21.50% was used for hatchery rearing and 6.56% was consumed during conditioning. In the nursery ponds, the water gain was primarily the regulated inflow coming through the irrigation channel. The total quantum of water used in the nursery rearing was 31,60,800 L [sic]. The initial filling and regulated inflow formed 42.60% and 57.40% respectively of water gain, while evaporation, seepage and discharge contributed 20.71%, 36.46% and 42.82% respectively to the water loss. The total water expended for the entire operation was 1,21,61,120 L [sic]. Water expense occurred to produce a single spawn in the hatchery system was calculated and found to be 0.56 L while the water expended to produce one fry was calculated as 4.86 L. The study fulfills the hydrological equation described by Winter (1981) and Boyd (1985). It also validates the water budget simulation model that can be used for forecasting water requirements for aquaculture ponds (Nath and Bolte, 1998).

The role for low carbon electrification technologies in poverty reduction and climate change strategies: A focus on renewable energy mini-grids with case studies in Nepal, Peru and Kenya

As a potential poverty reduction and climate change strategy, this paper considers the advantages and disadvantages of using renewable energy technologies for rural electrification in developing countries. Although each case must be considered independently, given a reliable fuel source, renewable energy mini-grids powered by biomass gasifiers or micro-hydro plants appear to be the favoured option due to their lower levelised costs, provision of AC power, potential to provide a 24. h service and ability to host larger capacity systems that can power a wide range of electricity uses. Sustainability indicators are applied to three case studies in order to explore the extent to which sustainable welfare benefits can be created by renewable energy mini-grids. Policy work should focus on raising awareness about renewable energy mini-grids, improving institutional, technical and regulatory frameworks and developing innovative financing mechanisms to encourage private sector investments. Establishing joint technology and community engagement training centres should also be encouraged. © 2011 Elsevier Ltd.
