On an experimental site in Hsinchu county, Northern Taiwan, a terraced rice field was used to investigate the soil erosion under the regular cultivation of rice in 2005, fallow in 2006, and planting with green manure in 2007. The results show
using rice-planted terraced paddy was more effective than that resulting from other uses. The government should formulate effective measures and maintain sustainable rice planting in the terraced paddies.

. In addition, due to the high irrigation share and reliable and effective irrigation facilities of cultivated land, China’s rice production is less climate-sensitive.
Using a data set with measures of Jiangxi’s climate and rice production, the AA. find the reason that during 1985 and 2004 ENSO’s well correlated with rainfall did not promote Chinese rice production. First, the largest effects of ENSO mostly occur
in the months when there is no rice in the field. Second, there is almost no temperature effect. Finally, the monthly distribution of rainfall is almost the same in ENSO and neutral years because the largest effects are during months when there is the least rain

Introduction of the red swamp crawfish, Procambarus clarkii, into California and its diffusion throughout northern California's rice paddies created the conditions for an incidental aquaculture economy in a landscape devoted to irrigated grain
This paper evaluates the effects of rice-husk ash with different rates of 0%, 10%, 20%, and 30% (v/v) on soil consistency limits (liquid limit, plastic limit) and soil compactibility parameters in Shanghai soils with different textures
A detailed study of a mechanical cultivation scheme for rice in the riverain grasslands of southern Sierra Leone suggests that its failure was due to faults in the technological organization and to the lack of support and understanding from central
Authoritative vignettes on the origin and spread of more than 70 plants that includes many of those common (e.g. wheat, rice, maize, coconut, date palm, apples, etc.) as well as those of lesser importance (e.g. macadamia nut, barbasco, quinoa

Since 1950's the central plains of Thailand, traditionally dubbed as Thailand's rice bowl, with the implication of an agrarian society practising rice monoculture, have seen drastic changes which unlike the politically sensitive northeast
, are little known. The book documents evolution in cropping patterns, new methods of cultivation, landholdings, labour availability and market opportunity. Water ceased to be a free good, became a managed resource which is increasingly scarce and hence subject
The economic efficiency of farmers growing high-yielding, irrigated rice in India
Les fonctions de profit permettent d'évaluer l'efficacité économique des choix technologiques. Elles sont appliquées à un échantillon de cultivateurs de variétés de riz à haut rendement du Tamil Nadu (Inde) et démontrent que petites et grandes
Use of sensitivity analysis to evaluate key factors for improving slash-and-burn cultivation systems on the Eastern Escarpment of Madagascar
The slash-and-burn pluvial ricecultivation that predominates in the agriculture of the Eastern Escarpment of Madagascar is causing ecological degradation and is aggravating poverty. Study uses sensitivity analysis, which uses existing knowledge
to set priorities among key factors associated with a development objective. Key factors in promoting sustainable development were found to be intensification and compact production units of cash crops (fruits and vagetables), irrigated rice

Rice production and related problems in Japan Rice production and the significance of Tohoku and Hokuriku
Malgré la diminution de consommation de riz/h au Japon et la politique de réduction gouvernementale dans l'agriculture japonaise, le riz reste le problème fondamental. Pour les deux régions considérées la surface cultivée représente 35% de la
surface cultivée nationale (pour le riz) et la production en est de 34-39%. Le déficit gouvernemental lié à la politique du riz a fortement augmenté entre 1969 et 1974. Pour l'enrayer il y a peu de solutions: 1) le gouvernement peut laisser le marché
