one of the most important aspects of sustainable development is sustainable agriculture. therefore, nowadays, achieving a sustainable agricultural system is an important policy in agriculture department of countries. the main objective of this study is identifying factors affecting stability of rice cultivation in the city of shirvan and chardavol in ilam province. this study was a survey and i...

Theoretically we understand the dimensions of both generic and specific adaptive capacity, however, there are few studies which document actual observed adaptive capacity. This study aims to address this gap by documenting the adaptive capacity of Indian rice production systems, an agrosocio-ecological system. We explore how Indian rice production systems have responded to historical climate sh...

A study was carried out at Mwea Rice Irrigation Scheme, Kenya, to assess the impact of rice husbandry on mosquito breeding and identify indigenous biocontrol agents with potential for controlling mosquito breeding in the scheme. The study established a close relationship between the schedule of the farming practices (particularly the flooding phase) and mosquito breeding. Two groups of agents, ...

This paper innovates as it tests two different hypotheses regarding climate impacts on agricultural markets in Brazil: farmers only observe the average climate conditions of their region when deciding the type and amount of crop/animal to grow/raise; and weather diversions from normal climate conditions deviate farmers from their optimal profits. Both hypotheses are not rejected by the data. Th...

Baligang is a Neolithic site on a northern tributary of the middle Yangtze and provides a long archaeobotanical sequence from the Seventh Millennium BC upto the First Millennium BC. It provides evidence for developments in rice and millet agriculture influenced by shifting cultural affiliation with the north (Yangshao and Longshan) and south (Qujialing and Shijiahe) between 4300 and 1800 BC. Th...

‘Golden Rice’ is a variety of rice engineered to produce bcarotene (pro-vitamin A) to help combat vitamin A deficiency1, and it has been predicted that its contribution to alleviating vitamin A deficiency would be substantially improved through even higher b-carotene content2. We hypothesized that the daffodil gene encoding phytoene synthase (psy), one of the two genes used to develop Golden Ri...
