One grain, one nation: rice genetics and the corporate state in early Francoist Spain (1939­1952.

This paper aims to show the links between rice genetics and the corporatist political economy of early Francoism. After investigating the transition from prewar rice producers' associations to a new federation embedded in a vertical union, I identify three main novelties of the new organization: its national scope, its need to address lack of supply rather than overproduction, and its hierarchical functioning. I then focus on the one state-owned agricultural station devoted to rice research, showing how its agricultural scientists shaped, and relied on, the state-controlled unions, both for producing and distributing new varieties of rice and for controlling the seeds farmers used. Finally, I explore how this relationship made it possible for the scientists to test, multiply, and distribute throughout the Spanish landscape the seeds they produced at the laboratory, thus putting hierarchical unity and autarky to work and demonstrating the role of scientists as active agents of state formation and landscape transformation within a corporatist political economy.

Institutional, policy and farmer responses to drought: El Niño events and rice in the Philippines.

Droughts are common recurring natural hazards in Asia, and El Niño events are particularly severe in the Philippines. This paper explores responses by farm households, irrigation system managers, and macro policymakers in the Philippines to El Niño. In response to the large 1997-98 El Niño, farmers in one major irrigation system significantly diversified their economic activities, hut the drought was so acute that many of these activities were not successful. Communication between meteorologists and irrigation system managers is strong, and irrigation system managers are aware of El Niño events in advance. Communication between irrigation system managers and farmer irrigation associations is also strong, and together they have developed response options that attempt to augment supplies of and more efficiently allocate scarce water. Water pricing is not used, however, and lack of cooperation among farmers results in sub-optimal outcomes. Macro-level policy responses in terms of rice imports and buffer stock management to protect poor consumers have improved substantially over time.

Estimating the benefits of pollution reduction on agricultural yields: Taiwan's air pollution emission fees program.

Taiwan's implementation of the 1997 Air Pollution Emissions Fees Program will conceivably lead to long-term reductions in pollution emissions. The purpose of this paper is to estimate the benefits to Taiwan from the expected reduction in crop losses as a direct result of such a decrease in air pollution. We employ a demand-supply framework for rice production to estimate the change in social welfare resulting from changes in the concentration of certain pollutants in the atmosphere. Our empirical results show that, in the year 1997, social welfare increments resulting from the decline in sulfur dioxide concentrations in the atmosphere ranged between US dollars 946200 and US dollars 2435800. Meanwhile, during the same period, the increase in social welfare due to the decline in the ozone concentration in the atmosphere ranged between US dollars 838100 and US dollars 1927000. The average benefit from the reduction in both sulfur dioxide and ozone concentrations is calculated to be between US dollars 2.67 and US dollars 6.86 per acre (for sulfur dioxide), and from US dollars 2.36 to US dollars 5.43 per acre (for ozone).

Energy intake during economic crisis depends on initial wealth and access to rice fields: the case of pregnant Indonesian women.

Starting in August 1997, Indonesia experienced a radical and rapid deterioration in its economy. Between 1996 and 1998, dietary intake during the second trimester was measured in 450 pregnant women in Purworejo, Central Java, Indonesia. Using six 24 h recalls we describe the consequences of the economic crisis on the energy intake of pregnant Indonesian women. Depending on the date of data collection, women were grouped into 'before crisis', 'transition' and 'during crisis'. Mean energy intake among groups was compared using ANOVA and Student's t-test. All groups of pregnant women already had a mean energy intake before the emerging crisis that was lower than the Indonesian recommended dietary allowances (RDA). Nevertheless, energy intake differed significantly among women with different education levels (P = 0.00) and from different socio-economic groups (P = 0.00). 'During transition', a significant decrease in energy intake was experienced by urban poor women (P = 0.01). Poor women with access to rice fields had a higher rice consumption than other groups throughout the period. Our results most likely reflect the effect of higher rice price on income and welfare. 'During crisis', energy intake improved among vulnerable groups, perhaps reflecting government intervention.

Glycaemic indices of different varieties of rice grown in Sri Lanka.

OBJECTIVE: Varieties of red raw rice are widely believed to have a better nutritional quality. The physiological effects of consuming different varieties of rice may not be so. The glycaemic index has been developed as an indicator of the physiological effect of foods. It is the glycaemic response of a 50 g carbohydrate portion of food expressed as a percentage of that of a standard. The objective of this study was to determine the glycaemic indices of different varieties of rice grown in Sri Lanka. DESIGN: Digestible carbohydrate content of 11 varieties of rice flour and bread were determined. Fasting blood samples followed by half-hourly samples for two hours were drawn after giving portions of either cooked rice or bread containing 50 g carbohydrate each. SETTING: Fibre mill in Gampaha district. SUBJECTS: Twenty-two fibre mill workers aged between 25 and 50 years. MEASUREMENTS: The area under the blood glucose curve (AUC) for varieties of rice for a subject was calculated. Average AUC of 3 values for bread were calculated. Glycaemic index of each variety of rice was determined from the above variables. RESULTS: Glycaemic indices of varieties of rice differ. The glycaemic indices of varieties of red raw rice varied between 56 and 73 and the variety Bg 350 had the lowest glycaemic index. There was no significant difference between mean glycaemic index of varieties of white raw and some varieties of red raw rice (p = 0.2). Parboiled varieties of red raw rice had a significantly lower glycaemic index than white raw rice (p = 0.04) and some of the red raw rice (p = 0.005). CONCLUSIONS: The glycaemic index cannot be predicted from the colour of the rice grain. Red parboiled varieties of rice and Bg 350 can be recommended for patients with diabetes.

Calidad de pastas suplementadas con salvado de arroz / Quality of supplemented with rice bran

En esta investigación se planteó como objetivo investigar el uso potencial del salvado de arroz (SA) en la elaboración de pastas largas tipo espagueti, dos de ellas fueron elaboradas con semolina de trigo durum (SD) suplementada con 10 y 20 por ciento SA previamente estabilizado y desgrasado; las otras dos pastas fueron elaboradas con harina granular (HG) igualmente suplementada 10 y 20 por ciento de SA. Se evaluó la composición proximal de las materias primas empleadas, se prepararon las mezclas en las proporciones establecidas y se elaboraron las pastas en un pastificio local. se les determinó su composición proximal, color, textura y calidad sensorial. Los contenidos de proteínas (13,2-15,0 por ciento), cenizas (1,47-3,09 por ciento) y fibra dietética (6,71-8,4 por ciento) de las pastas obtenidas variaron en relación directa al porcentaje de suplementación. Las pastas más duras y amarillas fueron las elaboradas con SD y 10 por ciento de SA. Las de mejor calidad sensorial fueron las de 10 por ciento SA para ambos tipos de sémolas. Se logró demostrar que se elaboraron pastas hasta con un 20 por ciento de suplementación con SA resultando productos con un mayor contenido de proteínas, cenizas y fibra dietética. Las pastas resultaron más resistentes a la fractura y con algunas características indeseables que le confiere el salvado de arroz tales como: puntos blancos regosidades y cambios de color

Wheat products as acceptable substitutes for rice.

The objective of the study was to compare the acceptability to semi-trained US American and Asian palatability panelist, of four wheat products processed to be possible replacers of rice in human diets. Products evaluated using rice as the control standard of excellence were steamed whole wheat, couscous (steamed, extracted wheat flour semolina), rosamarina (rice shaped, extracted wheat flour pasta), and bulgar (steamed, pre-cooked partly debranned, cracked wheat). Using a ten point hedonic rating scale, both groups of panelists gave rosamarina closely followed by couscous, most favorable ratings although these ratings were somewhat lower than that of the positive control, steamed polished rice. Bulgar wheat was given the lowest evaluation and was, in general, found to be an unacceptable replacement for rice by both American and Asian judges because of its dark, 'greasy' color and distinctive flavor. In their personal dietaries, judges included rice from 0.25 to 18 times per week with the Asian judges consuming rice significantly more times per week than did the American judges (10.8 +/- 4.71 vs 1.75 +/- 1.65, p < 0.01). However, rice consumption patterns, nationality, race, or sex of the judges was not demonstrated to affect scoring of the wheat products as rice replacers.

The nutritional significance of root and tuber crop development as staples in the Caribbean community.

The competition between cereals and root crops as CARICOM staples is described. The move to substitute locally grown food for imported wheat is shown to favor root crop development in the region. Against this background, traditional nutrition-prompted objections to wheat substitution by root crops are examined. Evidence is cited to show the essential adequacy of protein in root crops, except plantain and cassava and for all humans except perhaps some infants. The low protein in cassava and plantain, it is proposed, can be easily overcome in the process of local root crop development. Finally, it is argued that there exists the potential to obtain cheap calories from root crops. This and the generation of economic activity among small farmers, concomitant with root crop development, are seen as possible indicators of good nutrition for the region in the future.
