In this poster we present an approach to responding to complex questions in the agriculture domain, from specifications given by experts. We present in particular a semantic annotation procedure that would allow us to define accurate and domain dedicated forms of lexical semantics inference, in order to be able to match non factoid questions (i.e. questions whose response is a significant text ...

We assessed the interplay of artificial and natural selection in rice adaptation in low-input farming systems in West Africa. Using 20 morphological traits and 176 molecular markers, 182 farmer varieties of rice (Oryza spp.) from 6 West African countries were characterized. Principal component analysis showed that the four botanical groups (Oryza sativa ssp. indica, O. sativa ssp. japonica, O. ...

Abstract The exponential increase in population and economic activities has led to the intensification of agriculture aquaculture developing countries. Green Revolution 1960s Blue 1980s were giant steps this direction meet food demand burgeoning population. It resulted increased use modern technology for India. However, coping with ever-increasing adversely impacted our environment. Hence, it i...

AbstractIt is critically important to intensify farming systems in sub-Saharan Africa by disseminating improved agronomic practices and increasing the application of modern inputs (Chaps. 1 2 this volume). One region’s challenges that proper land preparation difficult due scarcity draft animals underdevelopment tractor rental market (Chap. 7). Our analysis rice production Cote d’Ivoire reveals ...

Sustainable farming is a popular concept, although very difficult to define (Viglizzo 1996). We believe that farming in the Argentine pampas has been sustainable in the broad sense. Over a span of three generations, productivity has increased, living standards have improved, and the farming sector has been the principal contributor to national development and the major earner of foreign exchang...

Global climatic change induced by emissions of greenhouse gases from human activities is an issue of increasing international environmental concerns, and agricultural practices and managements are the important contributors for such emissions. This study investigated dynamic emission of methane (CH4) from a paddy field in a rice-duck farming ecosystem. Three different cultivation treatments, na...

After a remarkable 86% increase in cereal production from 1980 to 2005, recent crop yield growth in China has been slow. County level crop production data between 1980 and 2010 from eastern and middle China were used to analyze spatial and temporal patterns of rice, wheat and maize yield in five major farming systems that include around 90% of China's cereal production. Site-specific yield tren...

in recent years sustainable development has been one of the concerns of man. to address this concern farming sustainable development will be one of the most important issues which must be dealt with. it seems that one of the necessary elements to further this goal is to have a serious look at indigenous knowledge of farming and particularly women’s knowledge. women and above all nomad women hav...

Rice paddies are artificial wetlands that supply people with food and provide wildlife with habitats, breeding areas, shelters, feeding grounds and other services, and rice paddies play an important part in agricultural ecological systems. However, modern agricultural practices with large-scale intensive farming have significantly accelerated the homogenization of the paddy field ecosystem. Mod...
