Most poor rural communities especially in third world countries are traditionally oriented towards agriculture. This makes biomass resources easily accessible in such areas although food can sometimes be a problem.
Food should be priority. A system must be designed so that waste products not only from cooking but after digestion be converted to fuels and/or compost. There have been successful efforts to convert cow dung wastes into gas but realize that methane is often the product and the carbon footprint is not altered as a result.
We should focus on byproducts (agricultural residue) obtained during crop production. Also, most of the agricultural based countries face problem related to crop residue disposal like South-East Asian countries where farmers burn the crop residue like Wheat straw and pigeon pea stalk in the farm land itself due to meer economic value which can be utilized for energy generation using scientific methods leading to lesser environmental issues.
Food is a basic necessity and should be prioritised whenever there is a food-fuel conflict. Biomass is broader than only food crops, hence non-food crop feedstock such as switchgrass and jatropha can be be promoted for energy production. Furthermore, biowaste (human waste, green waste, brown waste, food waste and animal waste) can all be used for the purposes of energy production. Crop residues have huge potential as feedstock for energy production.
Sin duda alguna la alimentación es una prioridad al momento de las selecciones racionales sobre el uso de la tierra para la producción. No obstante, la energía es crucial para el mejoramiento de la calidad de vida de la población, y en este siglo más. Por lo tanto, la planificación y la organización colectiva del territorio debe considerar proyectos comunes para el aprovechamiento de los residuos de la agricultura y los espacios de menor fertilidad, con el objetivo de buscar una proporción adecuada entre la seguridad alimentaria y la producción de energía.
