Stable isotopic compositions and elemental contents of the H, C, N, and O in 163 rice samples were analyzed. The samples were taken from three different farming countries; Japan (n = 103), United States of America (n = 30), and Australia (n = 21), in addition of Asian rice samples from Thailand (n = 2), Vietnam (n = 1), and China (n = 6) as comparison. They were mostly short grain samples known...

Modern bioenergy is seen as a promising option to curb greenhouse gas emissions. There is, however, a potential competition for land and water between bioenergy and food crops. Another question is whether biomass for energy use can be produced in a sustainable manner given the current conventional agricultural production practices. Other than the land and water competition, this question is oft...

In developing regions with high levels of poverty and a dependence on climate sensitive agriculture, studies focusing on climate change adaptation, planning, and policy processes, have gained relative importance over the years. This study assesses the impact of farmer perceptions regarding climate change on the use of sustainable agricultural practices as an adaptation strategy in the Chinyanja...

Sustainability is de®ned as the ability of a system to `continue'. In view of this de®nition, several aspects of the crop protection activity in organic farming are reviewed according to their ability to `continue'. As no absolute measure of sustainability is available, this analysis takes the form of a comparison between organic and conventional crop protection methods. Two elements of crop pr...

Shrimp farming has great potential to diversify and secure income in rural Sri Lanka, but production has significantly declined in recent years due to civil conflicts, some unsustainable practices and devastating outbreaks of disease. We examined management practices affecting disease prevention and control in the Puttalam district to identify extension services outputs that could support susta...

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, ...

The International Rice Research Institute (IRRI) has published the Rice Bibliography (RB) since 1963. IRRI had the Japan Library Office, which compiled the 1990-2000 Bibliography of Japanese Rice Research (BJRR) with the aims to provide more efficient information retrieval and bibliometrics in a specific-subject bibliographic database. We investigated the characteristics of Japanese rice resear...

Abstract Future food production is expected to meet the capacity in providing for 9.7 billion people world by 2050. As population rises, demand rice cropping areas Indonesia will double approximately 16.5 million ha 2040. Deploying arable land intensification alone would hardly fill gap. In Indonesia, around 140,000 – 187,000 hectares of agriculture have been lost due residential or industrial ...

The growing demanding from consumers for healthier foods, produced using environmentally friendly farming practices has resulted in the rapid expansion of organic farming. There are numerous studies about the importance of organic farming but the majority of the results are sometimes contradictory, inconsistent and show no clear link between organic farming practices and enhancement of the nutr...

Farming practices are known to exert strong control over the soils’ function to act as sources or sinks for greenhouse gases (GHG). A recent meta-analysis based on the evaluation of 74 published long-term system comparisons provides a comprehensive data base regarding soil organic matter development (SOM) and C sequestration potential of organic systems (Gattinger et al., 2012). Furthermore, th...
