Does climate change stimulate household vulnerability and income diversity? Evidence from southern coastal region of Bangladesh.

Bangladesh is one of the most climate-vulnerable countries globally, where the livelihood of agro-based dependent people became vulnerable due to different natural hazards, especially in the southern coastal part. This study investigates the influence of climate change on household vulnerability and income diversity, data collected from the climate-vulnerable coastal areas of Bangladesh. Both panel data regression and structural equation model were employed to examine the vulnerability status, whereas income diversity was measured through diversity index and "Type-66" livelihood strategy.

Assessment of alternative disposal methods to reduce greenhouse gas emissions from municipal solid waste in India.

Open dumping, the most commonly practiced method of solid waste disposal in Indian cities, creates serious environment and economic challenges, and also contributes significantly to greenhouse gas emissions. The present article attempts to analyse and identify economically effective ways to reduce greenhouse gas emissions from municipal solid waste. The article looks at the selection of appropriate methods for the control of methane emissions.

Development of a methodology for electronic waste estimation: A material flow analysis-based SYE-Waste Model.

Improved living standards and the share of services sector to the economy in Asia, and the use of electronic equipment is on the rise and results in increased electronic waste generation. A peculiarity of electronic waste is that it has a 'significant' value even after its life time, and to add complication, even after its extended life in its 'dump' stage. Thus, in Indian situations, after its life time is over, the e-material changes hands more than once and finally ends up either in the hands of informal recyclers or in the store rooms of urban dwellings.

Adsorption of hexa-valent chromium using treated wood charcoal--elucidation of rate-limiting process.

In the present study, locally available wood charcoal was used as an adsorbent to remove Cr (VI) from water. It was found to be giving poor removal efficiency whereby only 19% of Cr (VI) was removed. Considering the fact that wood charcoal possesses a honeycomb structure, an acid treatment was tried with HCl, H2SO4 and HNO3.

Replication of urban innovations - prioritization of strategies for the replication of Dhaka's community-based decentralized composting model.

Dhaka's community-based decentralized composting (DCDC) is a successful demonstration of solid waste management by adopting low-cost technology, local resources community participation and partnerships among the various actors involved. This paper attempts to understand the model, necessary conditions, strategies and their priorities to replicate DCDC in the other developing cities of Asia. Thirteen strategies required for its replication are identified and assessed based on various criteria, namely transferability, longevity, economic viability, adaptation and also overall replication.

Development of a purpose built landfill system for the control of methane emissions from municipal solid waste.

In the present paper, a new system of purpose built landfill (PBLF) has been proposed for the control of methane emissions from municipal solid waste (MSW), by considering all favourable conditions for improved methane generation in tropical climates. Based on certain theoretical considerations multivariate functional models (MFMs) are developed to estimate methane mitigation and energy generating potential of the proposed system. Comparison was made between the existing waste management system and proposed PBLF system.
