A brief discussion on energy use and greenhouse gas emmision in organic farming
Authors
Abstract:
Organic farming has become increasingly popular in the world. This is mostly attributed toescalating consumer concerns over the impacts of pesticides and chemical fertilizers on humanhealth as well as growing concerns over environmental pollution derived from modernagricultural practices, such as rising greenhouse gas emissions and water contaminations. Butdoes organic farming actually displace the environmental impacts commonly associated withconventional agriculture? In this article, we analysed the recent results of environmental impactsfrom organic farming. The aim was to fill the gap in assessing organic farming’s relationship toclimate change and evaluating sustainability of this system with a minimal energy andenvironmental damage over time. Despite the efforts of recent years, there is still considerableroom for the environmental optimisation of organic farming systems. The lower, similar orhigher impacts of organic farming, depended on crop types, site effects and differences inmanagement intensity. The conclusions here are exploratory and act as a call to action to naturalscientists to further explore how organic farming functions. Feeding the growing worldpopulation under conditions of restricted land for agricultural cultivation, restricted naturalresources and changing climate demands new and innovative solutions. These solutions requirethe agricultural community, to address agricultural systems from a perspective of increasing theproductivity per area with lower external inputs and enhancing resource use efficiency withoutnegative effects on crop yield and system sustainability.

Tillage effects on energy use and greenhouse gas emission in wheat-cotton rotation
Crop production process utilizes input energy and produces some biomass energy as output. During this process, greenhouse gases (GHGs) are also emitted which can make environmental risks. In this study, input and output energies, energy indices, and GHG emissions arising from inputs were estimated for wheat-cotton rotation under different tillage practices in Fars province. The study was condu...

In this research, the energy flow and production energy indices of canola cultivation in Trakya province of Turkey, Golestan and Mazandaran provinces of Iran were compared. Diesel fuel and chemical fertilizer inputs were the highest consumer of energy in the production of canola in these three regions. The results indicated that despite the higher energy use of machinery in Trakya province of T...

WRJAS Greenhouse gas emissions from dairy farming in Bangladesh
Livestock is a vital source of methane and nitrous oxide gas which are considered as hazardous greenhouse gas (GHG) causing global warming. This study was conducted to assess GHG emissions from different livestock categories of different (small, medium, large) dairy farming in Bangladesh by using IPCC guideline 2006 and CIGR 2002. The emission rate of CH4, N2O (mainly emits from manure) is incr...
