Impact of environmental production conditions on productivity and efficiency: A case study of wheat farmers in Bangladesh

Environmental conditions significantly affect production, but are often ignored in studies analysing productivity and efficiency leading to biased results. In this study, we examine the influence of selected environmental factors on productivity and efficiency in wheat farming in Bangladesh. Results reveal that environmental production conditions significantly affect the parameters of the production function and technical.. Read More

Progress and challenge towards reducing wheat spot blotch threat in the Eastern Gangetic Plains of South Asia: Is climate change already taking its toll?

Spot blotch, caused by Cochliobolus sativus, is a serious constraint to wheat production (Triticum aestivum L.) in the warmer plains of South Asia. Fourteen genotypes were tested in Bangladesh, India and Nepal during 6 years (2000–2005) to determine disease severity and resistance stability over these years. We analyzed the area under the disease progress curve.. Read More

Climate Change, Weak States and the “War on Terrorism” in South and Southeast Asia

Climate change is emerging as one of the key security challenges of the 21st century, a challenge that will increasingly have effects in the realm of counter-terrorism. Since January 2002, the United States Government has grounded its counter-terrorism policies within an international diplomatic framework of well-governed states that have the capacity and willingness to cooperate..

Spatial assessment of water quality in peripheral rivers of Dhaka city for optimal relocation of water intake point

In order to meet the ever increasing demand of drinking water, Dhaka Water Supply Authority (DWASA) of Bangladesh has installed a number of deep tube wells that tap the upper aquifers. However, in most parts of the city, the current groundwater abstraction exceeds the recharge rate, causing the groundwater to be mined systematically and be.. Read More

Salt marsh and seagrass communities of Bakkhali Estuary, Cox’s Bazar, Bangladesh

The species identification, distribution pattern, density and biomass of salt marsh and seagrass plants with some of the ecological parameters were studied in the Bakkhali river estuary, Cox’s Bazar, Bangladesh during the first half of 2006. Two salt marsh species (Spartina sp. and Imperata cylindrica) and one seagrass species (Halophila beccarii) were identified during this.. Read More

The imposition of participation? The case of participatory water management in coastal Bangladesh

Community-based Natural Resources Management (CBNRM) has been promoted as part of the development discourse on sustainable natural resources management since the mid-1980s. It has influenced recent water policy in Bangladesh through the Guidelines for Participatory Water Management (GPWM) where community-based organisations are to participate in the management of water resources. This paper reviews the extent.. Read More

Coping with riverbank erosion induced displacement

Each year, tens of thousands of people in Bangladesh are internally displaced as a consequence of riverbank erosion. Yet, such erosion does not draw the attention of policy makers in the same way that other natural disasters do and as a result, a number of coping mechanisms are employed by those affected, with the burden..

Development based climate change adaptation and mitigation: conceptual issues and lessons learned in studies in developing countries

This paper discusses the conceptual basis for linking development policies and climate change adaptation and mitigation and suggests an analytical approach that can be applied to studies in developing countries. The approach is centred on a broad set of policy evaluation criteria that merge traditional economic and sectoral goals and broader social issues related to.. Read More

Historical trends and future predictions of climate variability in the Brahmaputra basin

An innovative approach is developed and presented to assess historical climate variations and to quantify future climate change for the entire Brahmaputra basin. Historical trends in temperature and precipitation are analysed from 1900 to 2002 for the Tibetan plateau (TP), the Himalayan belt and the floodplains (FP) using a global 100 year monthly high resolution..

Effects of Black Carbon Aerosols on the Indian Monsoon

A six-member ensemble of twentieth-century simulations with changes to only time-evolving global distributions of black carbon aerosols in a global coupled climate model is analyzed to study the effects of black carbon (BC) aerosols on the Indian monsoon. The BC aerosols act to increase lower-tropospheric heating over South Asia and reduce the amount of solar.. Read More
