nt matter & 2007 IAgrE. emseng.2007.03.037 hor. : [email protected] Research on the incidence and effectiveness of natural crusting on slurry storage as a means of ammonia emission abatement was undertaken in studies at farm-scale, pilotscale and on a small-scale. At the farm-scale, slurry crusting was found to be commonplace across a large proportion (ca 80%) of slurry storage facilities, d...
Climate change impact studies on whole-farm systems require a holistic approach due to the complexities of biophysical processes, management and inter-relationships of land use within a single farm. This paper details the process of utilising a multiple-objective, strategic land use planning tool to conduct multi-factorial analyses on the impacts of climate change at the farm scale. Two example...
introduction: in this study, total factor productivity growth components in rough rice production are assisting by econometric approach and stochastic frontier function during 2005-2013 for several provinces (mazandaran province, guilan province, golestan province, fars province, khoozestan province). according to food and agriculture organization statics, iran is the 3rd importer and 20th expo...
This paper studies the effects of external economies of scale on households’ involvement in the non-farm sector. The focus of the paper is on the type of knowledge spill-overs that occur at the level of individuals; these relate to learning processes and non-market interactions. Nationally representative data on 8,100 households surveyed in 2006 and 2009 are used and unobserved heterogeneity an...
Increased prices for nonrenewable heating fuels (such as propane, heating oil, and natural gas) have residential and farm consumers seeking more sustainable solutions to their heating needs. Price increases among these fuels will remain a trend as a combination of decreased reserves and increased demand continues to limit supply (EIA, 2012). Pellets produced from abundant biomass sources—such a...
In the country, livestock is firmly integrated into the economic structure of farm and village life. Livestock raising is being recognized as a key element which contributes to rural income and to the efficient use of the available resources in the rural sector. The raising of farm animals is still on a small scale basis since it is intimately tied-in with farmers' activities and way of life. C...
Draft animal power (DAP) has been identified as an environmentally friendly technology that is based on renewable energy and encompasses integration of livestock and crop production systems. Draft animal technology provides farmers with a possibility to cheaply access and use manure from the draft animals and farm power needed to apply renewable practices for land intensification. Compared to m...
The wind industry in China has experienced a rapid expansion of capacity after 2009, especially in northwestern China, where the China’s first 10 GW-level wind power project is located. Based on the analysis from Moderate Resolution Imaging Spectroradiometer (MODIS) land surface temperature (LST) data for period of 2005–2012, the potential LST impacts from the large-scale wind farms in northwes...
While tissue culture (TC) technology for vegetative plant propagation is gradually gaining in importance in Africa, rigorous ex post assessments of welfare effects for smallholder farm households is lacking. Using recent survey data and accounting for self-selection in technology adoption, we analyze the impacts of TC banana technology on household income and food security in Kenya. To assess f...
Wind turbines generate electricity without directly emitting air pollutants that are known to affect the climate and human health. Wind turbines, however, do not operate in a vacuum. They are integrated into the larger electrical grid that includes coal and nuclear plants, natural gas turbines, hydroelectric dams, solar panels and other technologies. The interactions between these electricity s...
