In order to solve the problem that the performance of web application can't meet users' expectation when many users access dynamic data through the application, a data farming optimizing technique for web application is proposed. In the proposed technique, the web application is based on XML and the data are converted into XML format before being presented through XSL. To reduce page response t...

The benefits of organic farming to biodiversity in agricultural landscapes continue to be hotly debated, emphasizing the importance of precisely quantifying the effect of organic vs. conventional farming. We conducted an updated hierarchical meta-analysis of studies that compared biodiversity under organic and conventional farming methods, measured as species richness. We calculated effect size...

Organic farming practices have been promoted as, inter alia, reducing the environmental impacts of agriculture. This meta-analysis systematically analyses published studies that compare environmental impacts of organic and conventional farming in Europe. The results show that organic farming practices generally have positive impacts on the environment per unit of area, but not necessarily per p...

Seung Yong Han Introduction The purpose of this study is to assess the effect of out-migration at the household level on the decision to transition from farming to non-farming in the context of the socioeconomically changing agricultural region, Chitwan, Nepal, over 10 years between 1996 and 2006. In the face of social and economic changes in a region where agriculture is the main business, out...

Organic poultry production in the Netherlands is developing. Although consumers assume organic products to be safer and healthier, there are aspects of organic animal husbandry, like access to an outdoor run, that can result in increased risks of food safety problems. The aim of this study was to compare housing and management of organic and conventional broiler farms in the Netherlands and to ...

The Creole goat is a local meat breed well adapted to the tropical environment of Guadeloupe, a French island in the Caribbean. A survey of 47 goat farmers was conducted in May 2008 to describe the Guadeloupean goat farming systems. It was the preliminary step for the implementation of a breeding programme for Creole goats. Farmers had 31 does on average. A small number (4%) kept only Creole go...

Soil microorganisms play a crucial role in the biogeochemical cycling of nutrient elements and maintaining soil health. We aimed to investigate the response of bacteria communities to organic farming over different crops (rice, tea and vegetable) along the middle and lower reaches of the Yangtze River of China. Compared with conventional farming, organic farming significantly increased soil nut...

The salmon farming production chain is structured in four consecutive phases: freshwater, seawater, plant processing, and distribution and marketing. The phases interact in a pull manner, freshwater stocks fish to meet seawater’s demand, seawater produces to meet plant processing biomass demand, and the processing plant produces to satisfy consumers’ demand. Freshwater planning decisions are in...

Context & Rationale Despite a probable net reduction in the overall population since independence, there has been a small increase in the number of Armenia’s farming households. Many of these are relatively new and inexperienced farmers with very limited access to capital and farm inputs. Agriculture is the primary employer and accounts for about 28% of the GDP. Yet with few exceptions i.e. som...

Livestock farming systems encompass (i) grazing, (ii) mixed, and (iii) land-less systems. These systems convert crop protein into animal protein with an efficiency ranging from 5% to 45%, depending on animal type, system and management. The nitrogen (N) in the remaining fraction (55– 95%) is in urine and dung, and is conducive to N losses. This paper reviews N input–output budgets and N losses ...
