Estimation of Gross Domestic Product at Sub-National Scales using Nighttime Satellite Imagery

Abstract: There is a degree of uncertainty in the measurement and/or validation of national and sub-national economic data such as Gross Domestic Product (GDP). In some circumstances it can be very useful to have alternative measures of numbers like GDP to provide evidence for the validation or invalidation of claims of some nations or regions regarding their economic productivity. This research explores the feasibility of developing predictive relationships between observed changes in nighttime satellite images derived from the Defense Meteorological Satellite Program’s Operational Line scan System (DMSP-OLS), and changes in population and Gross Domestic Product (GDP).

Threats to the Sundarbans Mangrove Wetland Ecosystems from Transboundary Water Allocation in the Ganges Basin: A Preliminary Problem Analysis

Abstract: Through their complex network of river channels, the Ganges, Brahmaputra and Meghna Rivers cover an area of about 1.76 million km2, their boundaries extend across different countries such as Bangladesh, Bhutan, China, India, and Nepal. The Sundarbans are found at the coast of the Ganges River and are known as the world’s single largest mangrove forest with 3.5 percent of the world’s mangroves covering an area of 6017 km2. The Sundarbans wetlands act as a natural shield that protects the coastal area from storm surges and cyclones in pre and post monsoon periods. However, due to increased in irrigation of agriculture, industrial activity and the diversion of Ganges water at Farakka Barrage (India) in early 1975, both siltation and salinity have increased in the Sundarbans which is threatening the Sundarbans ecosystems. Consequently the dominant Sundari (Heritiera fomes) and Goran (Ceriops decendra) are affected by top-dying disease which is recognized as a key management concern. The Ganges water sharing is not just a geo-techno-political problem; it is also a humanitarian problem. So, interaction and educational awareness between concerned states are of great significant. The objective of this paper is to make a contribution towards the development and implementation of management plan for mangrove wetlands resources and to ensure that fresh water is supplied to the Sundarbans by the Ganges. Water salinity simulation and modeling would be a proper tool for decision making and allow planners to protect the Sundarbans ecosystems in future.

Impact of Urbanization on Land Use/Land Cover Change Using Remote Sensing and GIS: A Case Study

Abstract: The monitoring of urbanization is very important for the planner, management, governmental and non-governmental organizations and the scientific community, for implementing policies to optimize the use of natural resources and accommodate development whilst minimizing the impact on the environment. The study here aims at analyzing the changes that occurred in Land use/Land cover (LULC) over a time span of 1991 to 2007 using multi-date data of part of Punjab area, India and its relation to urbanization behavior. The digital data consisted of two sets of Landsat Thematic Mapper (TM) data and one set of IRS-1C data. Utilizing hybrid classification technique for interpretation and on-field validation, it has been found that there is increase in urban area by 10564.31 hectare in span of 16 years followed by other attributes. The other indicator parameter for urbanization that is Land consumption ratio (LCR) and Land absorption coefficient (LAC) show a significant change in their value at both spatial and temporal scale, LCR value changes from 0.048 to 0.109, whereas LAC varies from 0.414 to 0.266 in between 1991 to 2007.

Remarks on the calculus of variations on time scales

Abstract: The calculus of variations is a classical subject which has gain throughout the last three hundred years a level of rigor and elegance that only time can give. In this note we show that, contrary to the classical field, available formulations and results on the recent calculus of variations on time scales are still at the heuristic level.

Ecological Economics after the Millennium Assessment

Abstract: The Millennium Ecosystem Assessment has changed the way that we think about the interaction between social and ecological systems. By connecting ecological functioning, ecosystem processes, ecosystem services and the production of marketed goods and services it has identified ecological change as an economic problem. It has also drawn attention to a new dimension of the environmental sustainability of economic development. The Hartwick rule for the reinvestment of Hotelling rents on exhaustible and renewable natural resources provides one basis for evaluating the sustainability of extraction policies. The MA’s focus on the regulating services provides another. The regulating services offered by ecosystems limit the variability of ecosystem functioning, processes and the production of marketed goods and services. They help to conserve the resilience and hence sustainability of ecosystems. This offers both a challenge and an opportunity to ecological economists. The challenge is to understand the linkages between such services and the capacity of economic systems to function over a range of environmental conditions. The opportunity stems from the fact that the field is uniquely placed to meet this challenge.
