Focusing on the dynamics of species populations, this book explores the interactions between these populations and their environments within the field of population ecology. It traces the history of the Society of Population Ecology, highlighting its inaugural journal published in 1952. The text delves into foundational concepts, including Thomas Malthus' exponential law of population growth, which posits that populations will grow or decline exponentially under constant environmental conditions. This work serves as a comprehensive introduction to the principles governing population dynamics.

Focusing on agricultural drainage systems, this book explores how controlling soil water levels can significantly boost crop production. It highlights research demonstrating that improved drainage reduces variability in yields, ultimately lowering risks in producing high-quality, affordable food. Additionally, it discusses the multifaceted benefits of irrigation, such as frost protection and weed suppression, while contrasting it with rain-fed farming methods. Tailored for Indian students, the book offers current insights into effective agricultural practices.

Floods cannot be prevented but accurate information about them can reduce its severity to large extent. Remote sensing technology in general and SAR images in particular are known to be efficient and cost-effective when large areas affected by floods are to be mapped and analyzed. The main objective of the present work was to make a comparative analysis of different classification techniques for flooded area extraction on RADARSAT images. Assessment of accuracy and validation by appropriate method along with role of ancillary data for comparison of results were other issues discussed.
