Water management is a major concern across the world. From northern China to the Middle East to Africa to the United States, growing populations can stress local water resources as they demand more water for both direct consumption and agriculture. Irrigation based agriculture draws especially heavily on these resources and usually cannot survive without them; however, irrigation systems must b...
We examine the robustness of critical infrastructure networks in the face of terrorist attack, using a simulation experiment that incorporates link capacity; and an extension of data farming which we call network farming. Our results show that symmetrical designed networks generally outperform randomly generated networks, although ring-like structures are very vulnerable. Under targeted attacks...

Studying the sustainability of farming systems entails the integrated assessment of the strong interdependence between their environmental, economic and social attributes. Optimum allocation of water resources in a farming system improves the conservation and sustainability status of resources in addition to reducing the socio-economical damages. In order to analyze and assess the different asp...
The characteristic features of Japanese agriculture are rice production and its highly mechanized small scale farming system due to the limited land space. Agricultural production system in mechanization has been currently changed from mass production system to flexible manufacturing system, which became already much popular in industrial production one. This can be explained that the target cr...
Organic farming, a low intensity system, may offer benefits for a range of taxa, but what affects the extent of those benefits is imperfectly understood. We explored the effects of organic farming and landscape on the activity density and species density of spiders and carabid beetles, using a large sample of paired organic and conventional farms in the UK. Spider activity density and species d...
This study examines the impact of contract farming with Farmer Organizations on farmers’ income. Contract farming with farmer organizations is a smallholder farmer-inclusive contract farming system. Field surveys were conducted in August 2010 with 75 farmers (including 39 contract farmers) in Kampong Thom province, Cambodia. The analysis—i.e., using a treatment effects model—indicates that cont...
