This is the part of food which is being discarded or lost uneaten. This part of waste has a credible share in the municipal waste which is not common only for the developed countries but also familiar for countries like Bangladesh. Management of this extensive amount of waste has become unavoidable as this problem is affecting the city areas specially the capital city Dhaka in a comprehensive manner. Thereupon more attention is being sought to manage this issue by the policy makers, industrialists and consumers to avoid its economic, environmental and social impacts. This Study has focused predominantly on the current restaurant situation is holding on in Dhanmondi area. Structured questionnaire was designed which queried regarding the waste management practice, encouraging policy for reducing waste and their future contemplation in waste management. The study used a mixed-method approach, relying on document analysis and interviews with relevant persons in the restaurant industry. The study begins by exploring issues in the restaurant food system that result in the current levels of food waste. It then identified the current context of restaurants in Dhanmondi area. This study found that substantial regulatory changes are required to achieve substantial reductions in restaurant food waste. Along with the management practices few questions were related to the average number of attendants, the amount of produced waste, the type of waste, the expenditure part for the management practice. Besides questioning there was an attempt taken to prepare compost from the restaurant waste. To do that waste was being carried towards a barrel compost. After waiting for two months the compost fertilizer was ready to use and the amount of compost fertilizer that came out from 3.9 Kg restaurants waste was 326 g. After separating non-biodegradable material like bone, oily tissue and bottle caps, the amount of compost reduced to 180 g. The overall cost was within 3000 BDT (35 US dollar) for preparing the composting barrel.

for climate change adaptation owing to sustainable agricultural intensification in the
northwest region of Bangladesh. In this study, successive depletion of groundwater level
(GWL) with expansion of GW irrigation in Barind Tract has been discussed in the
background of Mohadebpur Upazila of Naogaon District and is conducted to assess the
nature of hydrograph which reflects the history of the behaviors of the parameters of the
shallow aquifers on the basis of lithology and other parameters concerning GWL depletion. It
has been observed that GW development, sources of recharge and properties of upper finer
materials influence the GWL depletion phenomenon. Hydrograph analysis, GWL mapping,
GW depletion rate calculation are done from GWL observation well data of Bangladesh
Water Development Board (BWDB). For scaling adjustment both groundwater table (GWT)
and lithology are plotted from the ground surface throughout the study and analysed for the
understanding of the geology surrounding the observation wells. From our analysis it has
been found that out of seven observation wells in the study area some of them show the
declining trend of GWL and excessive withdrawal of GW exceeds the potential recharge for
most of the observation wells. Crop diversification, artificial recharging, increasing
dependency on surface water, increasing irrigation efficiency, rainwater harvesting etc. can
be option for the area. Based on the simulation and GWL fluctuation analysis, availability of
GW resource has been assessed for the design year. In selecting design year, most weight has

been considered for 80% dependable of annual rainfall, because this is considered most
generally significant for domestic requirement considerations. The design year (2008 in this
study) is selected based on the return period analysis of rainfall from the precipitation
records for a period of 30 years spanning over 1980 to 2009 obtained from 18 rain gauge
stations located in and around the model area. However, development of numerical GW
modelling as well as simulation of GW flow has been performed in an integrated MIKE-11
and MIKE-SHE platform. From this assessment it is found that potential recharge for the
study area is 444 mm

Water quality index (WQI) is a valuable and unique rating to depict the overall water quality status in a single term that is helpful for the selection of appropriate treatment technique to meet the concerned issues. In this study, three different methods were used to evaluate the WQI named as; Weighted Arithmetic Index Method, Canadian Council of Ministers of the Environment Water Quality Index Method and National Sanitation Foundation Method. Essential parameters i.e. pH, total dissolved solids, dissolves oxygen, biochemical oxygen demand, electrical conductivity, chloride, turbidity, color, Silica, Iron, Phosphate were considered for calculating the WQI. According to Weighted Arithmetic Index Method the WQI value varied from 80 to 286 for the last five years. From the National Sanitation Foundation Method the WQI value was found within 36 to 56 for the study duration. The WQI value was varied from 3 to 16 according to Canadian Council of Ministers of the Environment Water Quality Index Method. Based on WQI values, the Shitalakhya river water was being classified as poor water for the above mentioned different years. Furthermore,the water quality were poor for different seasons as well.Among the different parameters, mostly turbidity, electrical conductivity, TSS, Iron were the parameters which caused the situation worst.Moreover, it was found there were no significant differences among the various methods for assessing WQI.
