The main slogan for the Year of rice is Rice is life. The initiative involves all the rice civilisations, both in Italy and in the rest of the world. The article also deals with other slogans such as Save rice save life, that means to increase
the production of rice in order to save the lives of million of people ; Rice with rice, which is related to rice and to the grawth of developing countries ; Beyond the rice, that means going beyond the cultivation of rice to achieve an ecologically sustainable
Rice self-sufficiency and rice research priorities in Ghana
Ghana's quest for self-sufficiency in rice is examined. Two issues are addressed. First, the social profitability of a policy of import substitution for rice in Ghana is examined from a national viewpoint. Second, the perspective gained is used
to draw implications for rice research in Ghana and more generally in West Africa. - (l'A.).
A practical method for rice acreage estimation with remote sensing
AVHRR ; Agriculture ; China ; Data processing ; Geographical information system ; NOAA ; Remote sensing ; Rice ; Statistics ; Thematic Mapper
This paper focuses on the operational method for rice planting area estimation, in which TM data is used to extract base rice area in a given year of 1992. The NOAA AVHRR data is used to predict the changing tendency of the rice planting area
. The method has been successfully used in extracting early rice area in Hubei Province in 1994 and acceptable result was obtained.
Rice re-cultivation in southern China : An option for enhanced climate change resilience in rice production
Adaptation ; Agricultural production ; Agroclimatology ; China ; Climatic change ; Drought ; Resilience ; Rice ; Southern China ; Spatial analysis ; Spatial distribution ; Water resources
Focusing on the spatial distribution of seasonal drought with rice and the practices to adapt to it, and based on an analysis of balanced water supply for and demand by rice at a growing season scale during 1981–2030, this paper assesses
the changing seasonal drought in the process of rice production under the changing climate in the future, and identifies general rice re-cultivation options for climate change adaptation. It is indicated that due to climate change, seasonal drought in major
rice producing areas tends to alleviate in general, late season rice in particular. Future climate change brings about a significant impact on the spatial/temporal distribution of water resources in rice producing areas in China. Based on pre-designed
adaptation actions for rice-re-cultivation, the rice cultivation pattern undergoes a significant alteration between 1981–2000 and 2001–2030.
A study on the possible impacts of climate warming on rice production in China
Agricultural practice ; Agricultural productivity ; Agroclimatology ; China ; Climatic variation ; Climatic warming ; Model ; Rice ; Simulation
Based on climate change scenarios, this study evaluates possible impacts of climate warming on rice production in China using numerical simulation experiments. The analyses include the changes of agroclimatic conditions for rice production
and changes in rice yield under two kinds of adaptation schemes.
The probability of the adoption of modern rice varieties (MVs) in Lowland Bangladesh. Case study in a backswamp located in the south eastern part of the country. In a large part of the lowland the MVs will be able to replace local mixed-sown tall
varieties only when the material cost of irrigation is reduced to a reasonable level. In the lower part of the area floating rice cultivation will remain. - (SGA)
This article briefly summarises the botanical results and data from archaeological excavations in China, India, and Thailand. There is no recent information on the origins of glutinous rice but botanical evidence points to a West African origin.
Coping with hunger : hazard and experiment in an African rice-farming system.
A case study of a Mende village in Sierra Leone based on field work undertaken in 1981-3 and 1985 indicates that the rice farmers are themselves innovators and their expertise is often more valuable than that of scientific advisors. - (EMS)
A model-based assessment of impacts of climate change on boro rice yield in Bangladesh
Agricultural productivity ; Agroclimatology ; Bangladesh ; Climatic variation ; Global change ; Model ; Rice ; Seasonal variation ; Temperature
In this study, the climatic crop productivity model YIELD has been applied to calculate rice productivity for the boro rice growing season (December/January-May) in Bangladesh under changing climatic conditions. The model estimates climatic
influences on various rice plant-growth parameters. The model was run using long-term average climate data of 12 meteorological stations located in the major rice-growing regions in Bangladesh to establish baseline estimates of yield. For the climate change
Technological innovation and agrarian change in the Philippines, with special reference to rice farming in the 1970s
The basic components of current technological innovation seeds, inputs, and credits failed to encourage the growth of domestic agro-industries. They brought the country to self-sufficiency in rice but created a new dependance on the foreign capital
Effect of fire on soil, rice, weeds and forest regrowth in a rain forest zone (Côte d'Ivoire)
