Climate Change issues: Challenges for Natural Resource Management in Bangladesh- a way forward

This study aimed to understand the climate change issues in Bangladesh by focusing on the specific operational guidance to Natural Resource Management (NRM) over time. The specific justification is used to figure out the factors that are responsible. To have an effective plan and guideline, this study has emphasised on some direct required actions and alternative options for long-run measures. Moreover, this study discussed the national lacking, limitation, required action and possible course of alternative option and a way forward to overcome the problems by the subject to current research effort and value. Finally, following on the raised issues, this study has introduced enhanced framework of strategies and guidelines to the concerned body and policy-makers in Bangladesh.

Climate change mitigation projections for ASEAN

ABSTRACT This article analyses climate mitigation impact once the Association of Southeast Asian Nations (ASEAN) introduce their respective Intended Nationally Determined Contribution (INDC) using dynamic non-linear computable general equilibrium modelling and 2010 input-output tables. The results indicate that atmospheric concentration of carbon and temperatures under the business as usual (BAU) scenario will fall from 390 PPM and 0.80°C respectively in 2010 to 351PPM and 0.79°C respectively, whereas under the optimal scenario it will fall to 329PPM and 0.71°C respectively in 2060. Cumulative climate damage under BAU and optimal scenarios will remain the same at MYR8.0 Billion, MYR14.3 Billion and MYR 24.8 Billion respectively in 2010, 2015 and 2020 but it will rise after that to MYR579 Billion under the former compared to MYR513 Billion under the latter in 2060. The reduction in carbon emissions shall also be achieved without a tangible fall in GDP per capita.

Agriculture and food security challenge of climate change: a dynamic analysis for policy selection

This study presents an empirical examination of climate change related to vulnerability impacts on food security and remedial adaptation options as a suitable strategy by prioritizing needs over a 50-year period. An Empirical Dynamic Commutable General Equilibrium Model for Climate and the Economy (EDCGECE) is applied using future strategies for Malaysia against a baseline scenario of existing conditions, following the top-down options. The model takes into account various climatic variables, including climatic damage, carbon cycle, temperature and rainfall fluctuation, carbon emissions, vulnerability and carbon concentrations, which were adapted from national observational predictions of climatic changes caused by global warming from 2015 to 2065. The results prioritize climate change mitigation for the future. Specifically, this study estimates Malaysia’s food sustainability prospects without adaptation actions and with 5 % to 20 % adaptation actions overtime in different adaptation scenarios, as contrasted with the baseline. The results indicate that food sustainability cost in the baseline in 2015 is 859.3 million US Dollar (USD), which is about a 30-35 % shortage compared with the national targets, and that the shortage will rise over time to USD 987.3 million in 2065. However, the cost of applying different levels of adaptation for food sustainability over time is rising considerably. However, the residual damage also decreases with all adaptation actions in the different scenarios. Thus, adaptation shows a positive sign for Malaysia’s agricultural sectors. As growth values are positive and show rising trends, therefore the projected adaptation policy can be effective for food sustainability for sustainable future strategies in Malaysia.

A science framework (SF) for agricultural sustainability

The significance of Science Framework (SF) to date is receiving more acceptances all over the world to address agricultural sustainability. The professional views, however, advocate that the SF known as Mega Science Framework (MSF) in the transitional economies is not converging effectively in many ways for the agricultural sustainability. Specially, MSF in transitional economies is mostly incapable to identify barriers in agricultural research, inadequate to frame policy gaps with the goal of strategizing the desired sustainability in agricultural technology and innovation, inconsistent in finding to identify the inequities, and incompleteness to rebuild decisions. Therefore, this study critically evaluates the components of MSF in transitional economies and appraises the significance, dispute and illegitimate issue to achieve successful sustainable development. A sound and an effective MSF can be developed when there is an inter-linkage within principal components such as of (a) national priorities, (b) specific research on agricultural sustainability, (c) adequate agricultural research and innovation, and (d) alternative policy alteration. This maiden piece of research which is first its kind has been conducted in order to outline the policy direction to have an effective science framework for agricultural sustainability.

Experiment of a Flat Plate Solar Water Heater Collector with Modified Design and Thermal Performance Analysis

An investigation is reported of the thermal performance of a flat plate solar water heater with a circulating absorber pipe surface. The thermal performance of the 2-side parallel serpentine flow solar water heater depends significantly on the heat transfer rate between the absorber surface and the water, and on the amount of solar radiation incident on the absorber surface. The modified pipe arrangement has a higher characteristic length for convective heat transfer from the absorber to the water, in addition to having more surface area exposed to solar radiation. It means during the operation of water heater, more solar energy is converted into useful heat. However, this modification has reduced the efficiency of the system marginally.
