Traditional food security strategies are reviewed and generally found to have a weak impact on lowering child malnutrition. Unless these programs are properly targeted and linked to employment and micro-credit opportunities for women, they are unlikely to be effective or sustainable. The links between food policy and nutrition security require greater attention to dietary quality through agricu...

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...

This paper presents a low power ZigBee sensor network characterized by bidirectional communication and control of inter-node data pack reception designed for use in agricultural fields. The network consists of end devices with sensors, routers that propagate the network over larger distances, and a coordinator that communicates with the computer, which in turns illustrates the data and controls...

BACKGROUND Several authors, most prominently Jared Diamond (1997, Guns, Germs and Steel), have investigated biogeographic determinants of human history and civilization. The timing of the transition to an agricultural lifestyle, associated with steep population growth and consequent societal change, has been suggested to be affected by the availability of suitable organisms for domestication. T...

The increasing of crude oil prices recently in the world, the need for an alternative source of fuel in the Indonesia is urgently required. In addition, growing concern about climate change is driving the need for “low-carbon” fuels. One highly potential form of renewable and low-carbon fuel is biogas from anaerobic digestion of organic wastes. Anaerobic digestion is a naturally occurring proce...

Between 1920 and 1939 a nearly six-fold increase occurred in the number of tractors on American farms, from 246,000 tractors in 1920 to 1,445,000 tractors in 1939 [5].

The squirrel-cage Induction motors (SCIMs) are approximately 80% of the overall electricity use in industrialized countries. In the agricultural and commercial sectors also, power consumption by high power SCIMs are quite substantial. On an average, the energy consumed by a motor during its life cycle is 40-80 times the initial cost of the motors. Therefore efficiency and power factor (PF) of t...
