Abstract

Purpose

Deepor Beel is one of the Ramsar Site and a wetland of great biodiversity, situated in the south-western part of Guwahati, Assam. With urban development at its forefront city of Guwahati, Deepor Beel is under constant threat. The study aims to calculate the lake water volume from the water surface area and the underwater terrain data using a triangulated irregular network (TIN) volume model.

Design/methodology/approach

The lake water surface boundaries for each year were combined with field-observed water level data to generate a description of the underwater terrain. Time series LANDSAT images of 2001, 2011 and 2019 were used to extract the modified normalized difference water index (MNDWI) in GIS domain.

Findings

The MNDWI was 0.462 in 2001 which reduced to 0.240 in 2019. This shows that the lake water storage capacity shrank in the last 2 decades. This leads to a major problem, i.e. the storage capacity of the lake has been declining gradually from 20.95 million m3 in 2001 to 16.73 million m3 in 2011 and further declined to 15.35 million m3 in 2019. The fast decline in lake water volume is a serious concern in the age of rapid urbanization of big cities like Guwahati.

Originality/value

None of the studies have been done previously to analyze the decline in the volume of Deepor Beel lake. Therefore, this study will provide useful insights in the water resource management and the conservation of Deepor Beel lake.

Abstract

General presidential elections are the achievements of the democratic forces and always arouse a multitude of social excitement. The presidential campaigns in years 1990; 1995; 2000; 2005; 2010; and present in 2015 became more and more professional. The role of planning and effective campaigns also increased. After more than 25 years of independence and after successfully carrying out the transformation of a new generation of voters born, raised, and educated in a democratic country whose political decisions are not conditioned in comparison to situation, Communist Poland has grown up and voted in 2015. The expectations of this generation are attributable to a good job, the ability to travel, and actively shaping their own lives. The existing political and party system no longer reflects the new social divisions which are becoming increasingly visible in the country.

Abstract

Interest in the field of entrepreneurship has significantly increased among academics, practitioners and government officials in the past decade both in the USA and in Europe. The increased interest is reflected in the increased number of courses, majors and minors at colleges and universities throughout the world; the increased number of endowed chairs; the increased number of journals in the field; the increased coverage of the field by the media; and the increased interest in the provision of government support. In light of this significant increased interest, it is important to understand the state of research in the field in Europe in the last few years, the focus of this article.
