In the previous article [Ammann, K. (2008) Feature: integrated farming: why organic farmers should use transgenic crops. New Biotechnol. 25, 101-107], in a plea for the introduction of transgenic crops into organic and integrated farming, it was announced that the complementary topic, namely that high tech farmers should integrate elements of organic agriculture, will be a follow up. Some selec...
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...
BACKGROUND Grassland degradation caused by overgrazing poses a threat to both animal husbandry and environmental sustainability in most semi-arid areas especially north China. Although the Chinese Government has made huge efforts to restore degraded grasslands, a considerable attempt has unfortunately failed due to an inadequate consideration of economic benefits to local communities. METHODO...
How to effectively promote the large-scale and market-oriented farmland leasing process in China is one of most important practical issues concerning current academic circle decision makers. However, restricted by situation rural social development, farmers’ spontaneous informal still widespread. Exploring long-term evolution characteristics at village scale great significance for optimizing le...
Simulation modelling is a methodology that appears highly suitable for use in farming systems innovation. However, if the aim is to improve farming systems by supporting farmer behaviour change, model-based approaches seem to have delivered surprisingly little observable benefit to date. This paper identifies the problems underlying this apparent lack of impact, and proposes better approaches t...
52 INTRODUCTION In the context of satellite communications (SATCOM), the term narrowband (NB) generally refers to the ultra-high-frequency (UHF)-, L-, and S-bands, where available bandwidth is limited compared to the higher-frequency bands. These lower-frequency bands in the 300-MHz to 4-GHz range are attractive to the DoD because of their better penetration into buildings and through foliage a...
Farming imposes unenthusiastic externalities upon society. It effects by differ‐ ent sources such as loss of biodiversity, land erosion, nutrient overflow, more water usage and pesticides. Optimistic externalities include respect of nature, independence, free enterprise, and the quality of air. Natural methods decrease some of these costs. It has been proposed that organic farming can reduce th...
The objective of this review was to present an update of the currently managed studies on the characterization physical, chemical, and sensory analysis of several tomato cultivars. This review has indicated the importance of farming system and genotype on sensory and biochemical characteristics. It is necessary to use selected genotypes responding positively to organic farming in terms of senso...
Farming households with close kinship ties in northeast Thailand have long been practising joint utilization of farmland. They used this multihousehold farming method even more actively to cope with the macroeconomic development beginning in the 1960s. A 1989 survey of a village by the author found more than one-third of farmland under such communal use. However, the share decreased drastically...
This paper addresses the problem of determining the sale price and the production quantity under supply uncertainty. The problem is commonly observed in the agricultural industry. We consider a firm that initially leases farm space in order to grow fruit. The realized amount of fruit supply fluctuates due to weather conditions, diseases, etc. At the end of the growing season, the firm makes two...
