Chapter
Increased concerns about food security in the context of increasing climate variability and globalized trade in agricultural commodities have led to a realization that scalable and technology-enabled methods of learning are necessary to help farmers access new science-based information. We have proposed an innovative Mobile Learning System based on...

Climate change is perhaps the most serious issue that affects food security of a very large number of human beings and animals. Impacts of climate change will be particularly significant in South Asia where most of food production comes from smallholder farms. Vulnerability in this region is twofold: production of important food crop varieties may...
Article
This paper presents spatio-temporal meteorological drought analysis of Pedda Vagu and Ookacheti Vagu watersheds of Mahabubnagar and Ranga Reddy Districts of Telangana state, South Central India. Rainfall anomaly index (RAI) and run analysis have been leveraged to assess drought characteristics at different stations in the basin. The study also pres...

In recent years, the Open Educational Resources (OER) movement has achieved considerable success within the academic community with respect to advocacy of the concept. As a result, many organisations such as the Commonwealth of Learning (COL), UNESCO and the International Development Research Centre (IDRC), in partnership with academic institutions...

In India, the phenomenon of open educational resources (OER) is made possible by the widespread use of information and communication technologies (ICT) and open source technologies. Over the last decade, national institutions have embraced the concept of collaborative teaching and learning practices. The idea of shared resources has been successful...
Article
Drought occurs due to a deficiency of precipitation over an extended period of time, usually for a season or more, affecting virtually all climate regimes. This deficiency results in water shortage for some activities, group or environmental sector, causing economic losses and significant damage to human lives. Furthermore, water demand for growin...

The Open Educational Resources (OER) movement has gained momentum in the past few years. With this new drive towards making knowledge open and accessible, a large number of OER repositories have been established and made available online throughout the globe. However, despite the fact that these repositories hold a large number of high quality mate...

Abstract — Agriculture in India, or “gambling with monsoons,” as it’s often called, is dependent on such weather. A monsoon failure leads to droughts and the rural Indian farmers are the worst affected, making drought identification, monitoring and characterization at the village level crucial for drought proofing in rural areas. The Mahabubnagar r...
Chapter
The linkages between agriculture and climate are pronounced and often complex. Agricultural systems are most sensitive to extreme climatic events such as droughts, floods and hailstorms, and to seasonal variability and changing rainfall patterns. The role of inadequate institutional support is frequently cited in the literature as a hindrance to ad...
Article
The National Agricultural Innovation Project (NATP) of The Indian Council of Agricultural Research (ICAR), New Delhi supported a Consortium project on the use of ICTs in developing a multimedia data base of Best Management Practices (BMPs) for few important crops and provide solutions to production problems faced by farmers across the country. Thro...
Chapter

Insufficient scientific inputs in terms of research and development are responsible for low productivity of rainfed systems in the semi-arid tropics (SAT), in addition to biophysical and social constraints such as poor infrastructure, inherent low soil fertility, frequent occurrence of drought, severe degradation of natural resource base, and poor...

Welcome to the Open Education Resources survey which aims to identify the current state of play in the Asian Region with respect to OER practice. This survey mainly concentrates on, but not limited to, the current situation in Malaysia, Vietnam, Indonesia, India, Philippines, Japan, China and Hong Kong. The main objective of this study is to establ...
Conference Paper
Keyword assignment is an important step towards semantic enablement of the web. In this paper we describe a taxonomy called Agrotags which is designed for tagging agriculture documents. Agrotags is a subset of Agrovoc and is much smaller: about 2100 as against 40,000. Agrotags is manually created by carefully examining each of the Agrovoc terms for...
Article
Women have a key role in the organization of agricultural production. Their participation in agri-related projects is not only to make food available for the households; they participate to satisfy practical and strategic needs, where the latter are essential for self-worth. Women are one of the most vulnerable groups to bear the consequences of cl...
Conference Paper
The Consultative Group on International Agricultural Research (CGIAR) is engaged in research for development and plays an important role in mobilizing science to benefit the poor through its multiple centers and thematic programs. Additionally, the CGIAR centers are engaged in knowledge management and offer training for capacity building. The Learn...
Article
Full-text available
Agricultural information management needs to be responsive to the needs of varied stakeholders, and content repurposing to suit multiple audiences is a key requirement. A framework that combines the semantic web techniques of Topic Maps (TM) and a global agricultural thesaurus, the FAO AGROVOC, has been developed on a pilot basis for five crops. Th...
Article
Full-text available
There has been significant interest in applying the practices of semantic web to build an online repository of agricultural information (example: FAO-India efforts in AGROPEDIA). We will describe the results from a preliminary investigation into the use of a semantic tool for Mediawiki with content from the agricultural domain as the substrate. The...

Full-text available
Drought affects hundreds of millions of people in the developing world and causes serious disruption of social and economic activities. Preparedness is better than relief and information is the backbone of drought preparedness. In this paper we report the results from a study in the use of GIS-derived products to assess micro-level drought vulnerab...
Conference Paper
Climate variability creates risk in rainfed farming. Risk in turn discourages investment by farmers, governments and development agencies. For instance, in dry regions recurrent droughts debilitate and destabilize poor, agricultural-based societies, and contribute to land degradation by reducing vegetative cover and water supplies. Drought triggers...

Indian agriculture is characterized by an economic symbiosis of crop and livestock husbandry. Within the livestock sector, dairying provides the greatest opportunity for creation of employment and income generation. Landless, small-scale and marginal farmers form the majority of the dairy farming community and dairy farming constitutes an important...
Conference Paper
The details about the Aqua choupal Model of the Indian Tobacco Company (ITC) are presented in this paper. The case study explains how ITC is using information and communication technologies (ICTs) to identify solutions to export oriented problems of the Indian shrimps, by keeping track of the entire supply chain including quality and origins of the...

The need for improved agricultural extension throughout the developing world has never been greater. Agricultural and rural development and hence rural extension continue to be in a phase of transition in this part of the world. The vulnerability of farming in the developing world to climate change, to changes in natural resources quality (includin...
Article
With natural calamities such as drought becoming a recurrent phenomenon, Science-based interventions using GIS-based tools to predict the severity of drought in an area can potentially contribute to mitigation efforts.

Conference Paper
Recurrent droughts affect vast areas of South Asia, and are increasingly becoming a cause for concern. Information is the backbone of drought preparedness. In order to mitigate the ill effects of drought, there is an urgent need for sustained information, education and social mobilization efforts to reach vulnerable rural communities. ICT mediated...
