Abstract: Xiamen Park Expo Garden, full name is Xiamen international expo garden, is located in Jimei Zhongzhou Island, Xinglin Bay Xiamen, the hometown of Mr. Chen Jiageng, the vast Xinglin Bay water area is the background. The planning area covers a total area of 10.82 square kilometers, including 5.55 square kilometers of land area and 5.27 square kilometers of water area. It is composed of 9 islands and 2 peninsulas. Since its construction in 2007, Xiamen Park Expo Garden has greatly promoted the development of tourism, ecological services and real estate in Jimei District of Xiamen City, and also greatly promoted the development of the surrounding economy. Using the method of ecological economics and mathematics analysis, such as carbon tax law, afforestation cost method, market value method, industrial oxygen production method, expense method, shadow engineering method, conditional value method and achievement reference method etc, some ecological services of Xiamen Park Expo Garden are valued, such as fixed carbon dioxide, release oxygen, air purification, water storage, tourism and leisure, education and scientific research, the real estate value. The total value is about 484 million, of which the value of tourism and leisure is the largest, it is 375.9766 million yuan, and occupies the proportion of 77.71%. By analyzing the total value of the marginal effect of main components, some suggestions are proposed for the construction and development of Xiamen Park Expo Garden.

Abstract: Brick kilns have been the backbone of the construction industry in Bangladesh due to non-availability of stones in enough quantity. Brick kilns in the country use age-old technologies, which are inefficient with high emissions. In addition, the industry uses low quality of coal as fuel, with high ash and sulfur content; there by contributing to the worsening of air quality. This paper discusses the developments in brick making during the past 30 years in search of higher energy efficiency and lower pollution. It is seen that the progress in pollution abatement and energy efficiency improvement have been slow; resulting in considerable health burden for the population and other economic losses for a long time. In recent years, some affordable designs of low polluting and more energy efficient kilns have been introduced by the Department of Environment (DOE) through a number of programs; including World Bank financed Clean Air and Sustainable Environment (CASE) Project. These efforts have led to considerable pollution reduction i.e., by more than 70% for PM (Particulate Matter) and coal consumption reduction by around 30% at individual brick kiln level. Large low emission industrial kilns with imported technology are also being established. However, the rollout of these energy efficient and low emission technologies in substantial numbers is yet to be achieved. Some moves are also afoot to increase the use of non-fired bricks. In order to achieve quick all-round gains, both push as pull factors for the change in current situation need to be mobilized. What is needed is a well-articulated time bound ‘Theory of Change (ToC)’ for green and clean brick industry in the country. Success in this endeavor will substantially reduce the air pollution levels bringing health benefits to local population. Concurrently, it will also reduce the land-use footprint, top soil use, loss of agricultural productivity and Green House Gas (GHG) emission from the brick kilns. In addition, this will also improve employment and working conditions for labor employed in the brick sector. A simplified ToC for a cleaner and greener brick sector for a ten years’ period is outlined in this work.
