Deforestation in Bangladesh, has reached an alarming rate in recent years. The forest coverage of Bangladesh is one of the lowest and the deforestation rate is the highest of any country in the world. Coupled with the process of deforestation, flawed afforestration programmes have seriously exposed Bangladesh to environmental vulnerability. Considering this situation various strategies should be taken at different levels. The main objective of this paper is to suggest the possible steps that Bangladesh could halt and reverse the trend of deforestation. An extensive literature review and structured interviews of key informants have been used to collect relevant information to understand the reasons and consequences of forest degradation in the country. Based on the information gathered, this paper suggests some positive steps where the Government could be the main mitigating actor by implementing integrated programmes, which will also ensure mass awareness and wider impact.展开更多

In terms of an intrinsic mechanism, an appropriate measure of leverage ratio should be the liability/asset ratio. In their business operations, it is inevitable for real-economy enterprises to incur liabilities arising from business and financial transactions. Therefore, the significance of deleveraging operations is to reduce the leverage ratio below a certain threshold to effectively prevent risks arising from an excessive leverage ratio, rather than to reduce the liability ratio of real-economy enterprises to zero. For real-economy enterprises, a key question is how to adjust their debt structure by reducing current liabilities and increasing mid-and long-term liabilities. The debt structure of real-economy enterprises is primarily determined by their financial structure. Hence, it is essential to adjust the financial structure in order to improve the debt structure of real-economy enterprises and increase the share of direct finance. Various risks exist in the combination of shares and bonds within the banking system, investment-lending linkage and market-based debt-to-equity operations, which are options in reducing the leverage ratio for real-economy enterprises. From the standpoint of giving play to capital market functions, it is advisable to increase the issuance of midand long-term corporate bonds and preferred stock, restrict non-financial listed companies from engaging in financial operations and the shareholders of listed companies from selling shares, encourage equity investment institutions to enhance equity investment in realeconomy enterprises, and further develop the financing function of the stock market.展开更多

The results show that increase in demand for feedstock to produce bio-ethanol will lead to large increase in the prices of agricultural products. The increase in prices will trigger a significant rise in the production of feedstock at the cost of lower rice and wheat production. The study also reveals that the impacts of bio-ethanol on farmers" incomes vary largely among regions and farmer groups. Given the expected expansion of bio-ethanol production in the future, and the limited land resources for feedstock production in China, the viability of different crops as feedstock for bio-ethanol requires careful analysis before a large-scale expansion of China's bio-ethanol program. Bio-ethanol production in China should be relying more on the second generation of bio-ethanol technologies (i.e. using celluloses to produce bio-ethanol), and China's government should increase research investment in this field.展开更多

IntroductionThere have been numerous studies on free capital mobility, its management and impact on developing countries’ economy during the past decades. International capital flows create opportunities for portfolio diversification and risk sharing. In classical cases, capital mobility permits a more efficient global allocation of savings and directs resources toward their most productive uses (Fischer, 1998, etc.). However,展开更多

Chinas rapid economic expansion hasaffected the quality of its growth, with rising material and energy consumption and imbalancedeconomic structure as the main manifestations. Regarding macroeconomic policy options in2004, decision-makers should shift the policy focus from control of deflation to preventionof inflation; the pace of economic growth should be properly set; a balance betweenconsumption and investment should be strengthened by controlling excessive expansion ofinvestment, and industrial restructuring should be conducted in a coordinated manner onthe basis of properly controlling the overly rapid industrial growth; policies should becontinued to boost exports and sustainable growth of foreign investment; and more effortsshould be made to accelerate the change in the mode of economic growth.展开更多
