Seismic Micro-zoning in landslide-prone Urban Areas: A GIS Based Instability Assessment at Castelfranci City (Italy) | Chapter 1 | Research Advances in Environment, Geography and Earth Science Vol. 2

The present study focuses on a Gis-based strategy to draw Seismic Micro-zoning instability maps in landslide-prone urban areas. As concerns landslide prevention and mitigation policies at the urban scale, the ability of Geographical Information Systems (GIS) to combine multi-layered information with high precision enables technicians and researchers to devote efforts to managing multiple hazards, such as seismically induced instability in urbanized areas. Gis-based Newmark's method is traditionally used for measuring the permanent displacements caused by seismic activity on natural slopes at regional and municipal scales.  Hereinafter, the case study of Castelfranci city (Campania, southern Italy) has been studied. This small town, hosting two thousand inhabitants, suffers from the seasonal reactivation of landslides in clayey soil deposits due to rainfall but it is exposed to a high seismic hazard. This study investigates possible seismically induced hazard scenarios within the Castelfranci municipal territory aimed at estimating the slope permanent displacements triggered by the strongest historical seismic event that hit this area: the 1980 Irpinia earthquake. Two simplified relationships relating peak ground acceleration and Arias intensity to permanent displacements have been used and compared. Both equations gave similar permanent displacement values: the two analyses pointed out that multiple portions of both active and quiescent landslide bodies within the Castelfranci urban area can be moved by tens of centimeters generating a high-risk scenario for structures and persons.

Information Technology in Indian Agriculture: An Approach towards Developments and Perspectives | Chapter 10 | Current Topics in Agricultural Sciences Vol. 6

 In Indian agriculture, information technology (IT) plays a significant role. Information technology (IT) can be described as the use of data to enable or improve products or processes. This chapter looks at a variety of information technology uses in agriculture and speculates on their future prospects. Precision farming is a farm management approach that uses precise amounts of crop inputs such as fertilisers, herbicides, and irrigation water to increase crop output and quality while reducing pollution. Support and information systems can be established to investigate efficient cropping patterns in order to maximise productivity per acre and reduce waste, for example, by not applying more nutrients than the crops require. Applications for climatic and flood forecasting can be created to help farmers deal with disasters. Weather forecast information that is accessible at the proper moment can be extremely useful in assessing disaster risks and developing a risk management strategy. The use of Information and Communication Technology (ICT) to boost India's food output and productivity is a possibility (ICT). Several mobile-based projects have been created to give farmers with 24/7 access to information and knowledge. Farmers and cooperative groups have benefited from the use of satellite-based remote sensing data, which is provided by many government and public institutions. In the extension component of agriculture, e-Learning plays a critical role in imparting training on new IT breakthroughs. To address conflicts via the Internet, online dialogues using chat capabilities may be encouraged. Using techniques like video conferencing, critical choices about policy issues can be made in real time. The goal of this paper is to describe major IT advances in the context of Indian agriculture and to suggest a course of action.
