I develop a two-period stochastic dynamic programming model to explain the interaction between fertilizer use and off-farm labor supply. I use a well-known sample of farmers in the semi-arid tropics of India to test the model. I find that fertilizer use responds strongly to wages in the village labor market and that irrigation raises fertilizer use, while larger farmers use less fertilizer than...

In the process of "tatami" mat production, from cultivating to weaving, rush farmers are exposed to "sendo" (dyer's earth) dust using it to prevent fading of the "tatami" mat color. It has been found that the workers tend to develop a relatively early stage of pneumoconiosis after about 20 years of this work. In 1980, 51 male (58.6 years old) and 37 female (54.4 years old) rush farmers, some of...

BACKGROUND Although women occupy a central position in agriculture in many developing countries, they face numerous constraints to achieving their full potential including unequal access to assets and limited decision-making authority. We explore the intersection of agricultural livelihoods, food and economic security, and women's sexual and reproductive health in Iringa Region, Tanzania. Our g...

BACKGROUND Ordinary screening of transfusion-transmissible infections (TTIs) among blood donors is essential for blood transfusion. Although there is several TTIs studies focus on human immunodeficiency virus, hepatitis B and C viruses, and Treponema pallidum infections in China, it is no data to illustrate any firm conclusion from Shiyan City, Central China. It aims to verify the seroprevalenc...

AIM Coccidiosis is an important enteric parasitic disease of poultry associated with significant economic losses to poultry farmers worldwide. This survey was conducted from June 2014 through July 2015 with the main goal of investigating the prevalence and associated risk factors of coccidiosis among village and exotic breeds of chickens in Maiduguri, Northeastern Nigeria. MATERIALS AND METHO...

Recent increases have been reported in industrial countries for several sites of cancer. The causes of these increases remain unknown. Efforts should proceed to identify those occupational groups with increases in the same sites, as these may indicate relevant exposures. Two analyses were undertaken: trends in cancer mortality in industrial countries were reviewed to identify recently increasin...

BACKGROUND Globalization-related measures to liberalize trade and stimulate export production were applied in Uganda in the late 1980s, including in the coffee production sector, to revitalize agricultural production, increase incomes to farmers and improve rural food security. OBJECTIVE To explore the different effects of such measures on the health and dietary outcomes of female coffee and ...

Production by smallholders in rural Kenya is limited institutional, technical and investment constraints. Female farmers are the majority among have significant roles agriculture; nonetheless, they face constraints accessing resources. Recent primary data of 347 (proportional random sampling) was used to examine: (a) factors affecting women’s participation (b) influencing female farmers’ decisi...

1. The energy balance and activity allocation of eight male and eight female Indian farmers were measured for 4 d during 10 months in both the dry and wet seasons of 1983. 2. All food prepared and eaten was weighed and nutrient values were calculated from food composition tables. 3. Average energy costs per unit mass for fifteen tasks were estimated from data obtained using a Kofranyi-Michaelis...
