An incident information management framework based on data integration, data mining, and multi-criteria decision making

An effective incident information management system needs to deal with several challenges. It must support heterogeneous distributed incident data, allow decision makers (DMs) to detect anomalies and extract useful knowledge, assist DMs in evaluating the risks and selecting an appropriate alternative during an incident, and provide differentiated services to satisfy the requirements of different incident management phases. To address these challenges, this paper proposes an incident information management framework that consists of three major components. The first component is a high-level data integration module in which heterogeneous data sources are integrated and presented in a uniform format. The second component is a data mining module that uses data mining methods to identify useful patterns and presents a process to provide differentiated services for pre-incident and post-incident information management. The third component is a multi-criteria decision-making (MCDM) module that utilizes MCDM methods to assess the current situation, find the satisfactory solutions, and take appropriate responses in a timely manner. To validate the proposed framework, this paper conducts a case study on agrometeorological disasters that occurred in China between 1997 and 2001. The case study demonstrates that the combination of data mining and MCDM methods can provide objective and comprehensive assessments of incident risks.

Risk assessment of drought disaster in the maize-growing region of Songliao Plain, China

This study presents a methodology for risk analysis and assessment of drought disaster to agricultural production in the maize-growing area of Songliao Plain of China based on Geographical Information Systems (GIS) from the viewpoints of climatology, geography, disaster science, and environmental science and so on. Crop yield–climate analysis and regression analysis were employed to analyze and quantify relationships between the fluctuation of maize yield and agro-meteorological disasters, and to evaluate the consequences of drought disaster based on historical climate, crop yield, crop sown area, crop damaged area and crop loss data from 41 maize-producing districts of Songliao Plain (1949–1990). The model of risk assessment of drought disaster combined the occurrence frequency, duration and intensity of drought, spatial extent of damage caused by drought and regional production level of maize were developed using a method of quantitative risk analysis. It is shown that drought was the greatest agro-meteorological disaster. Among all agro-meteorological disasters, drought occurs with the highest frequency, covers the largest area, and causes the greatest loss to agricultural production and economy in the region. From 1949 to 1990, the negative value years of the fluctuation of maize yield due to agro-meteorological disasters accounted for 55%, of which 60% was caused by drought. A significant positive relationship between the negative values of fluctuation of maize yield and drought affected area was found, which indicates that the adverse impacts of drought on maize production are similar to the damage extent of drought disaster. According to the risk extent of drought disaster to maize, the Songliao Plain was divided into four sub-regions: high risk zone, medium risk zone, low risk area and slight risk zone by using fuzzy cluster analysis. It showed the risk degree of drought disaster in the Songliao Plain increases gradually from south to north and from east to west. The information obtained from interviewing the district official committees in relation to result compiled was statistically evaluated. The results obtained in this study can provide the basis for developing strategies to mitigate drought and reducing the losses, and to ensure agricultural sustainable development.

Some Aspects of Agro-meteorological Disaster in China

Aspects of disaster-formative factors and environments, disaster-genetic regularity and their effects on agriculture, the characteristics of the occurrence of agro-meteorological disasters and their impact are assessed in this paper. The high risk level and high vulnerability of these disasters are pointed out. In China, meteorological disasters, which account for 80 percent of all natural disasters, are characterized by their high frequencies, broad range and increasing tendency. The annual average area of disaster-affected fields nationwide amounts to 30.7 million hectares, 62 percent of which comes from droughts, 24 percent from floods, 8 percent from hail d violent winds, 6 percent from freezing injuries. These disasters lead to more than 10 billion kilograms of losses of grain yield. Among all these direct economic losses arising from natural disasters, 60-70 percent results from droughts and floods. The occurrence of agro-meteorological disaster has peculiarities of quasi period and simultaneity, and disaster effects may be worsen by artificial environmental deterioration.

A Study on the Relationship between the Fluctuation of Maize Yield and Meteorological Disasters in Lishu County of Jili Province, China

Lishu county is one of the main maize-producing areas on the well-known Maize Belt of the Songliao Plain in China. Although the natural conditions are advantageous to maize growth, agrometeorological disasters frequently occur and maize yield fluctuates over the years due to the effects of an unstable monsoon climate. In the paper, firstly, characteristics of fluctuation of maize yield are made quantitatively and assessed using the method of Crop yield-climate analysis. Secondly, the cycles of fluctuation of maize yield and meteorological disasters are analysed with using the method of Deviation, Spectrum analysis. Finally, for making father research on the dangerous extents to maize yield, meteorological disaster years are divided into different types through the method of Fuzzy mathematics. Based on the study, probabilities of disasters occurrence and degrees of reduction in maize yield are calculated, and correlation analysis on relationships among fluctuation of maize yield, disaster area and causing disaster area is carried out.

On the Agrometeorological Disasters (AgMDs) in Henan Province, China and their Prevention

Based on an analysis of natural disasters which occur in some major damage regions in Henan Province, China, including frequency of disasters, their objects and characteristics, this paper emphasizes the fact that many AgMDs are disastrous consequences resulting from Man's own doing. Considerable agricultural yield reduction over a vast extent of fields has always resulted from AgMDs, especially from droughts and floods occurring in areas of Henan Province.These disasters are characterized using the concepts of synchronizing, overlapping, alternating, succesive occuring etc.. The new point of view of “natural disaster masses (or chains)”, “entropy addition” and the “systems analysis method” should be applied in analysing, understanding and preventing AgMDs.In the last part of this article, some measures and proposals for preventing and fighting disasters are presented.

A survey of agrometeorological disasters in South China

The paper discusses climatic features of tropical and sub-tropical provinces of China. Warmth and abundant rainfall allow for intensive agricultural development. However, the region does suffer weather situations that are devastating to crops. A number of these, such as drought, flooding, typhoons, cold waves and hail are discussed, and their climatology presented. The definitions are given of drought, flood-waterlogging, cold-wave and cold-dews wind as these are used in China. The latter phenomenon is a fall season condition with low temperature and either dry and windy, or cloudy and drizzly which is very destructive of late season rice. Information on the occurrences of these adverse situations are presented together with their distribution in South China.
