To better promote forest resource management and strengthen the development of forest carbon sink marketization, this paper studied the accounting of forest carbon sinks from 2003 to 2008 based on a system of national accounts (SNA) and data from the latest forest resources inventory in China. The study calculated the value of forest carbon stocks at a total of RMB 817.13 × 10^9 yuan in 2003 and RMB 839.93×10^9 yuan in 2008, with an average annual increase of 0.55 % from an increase in physical carbon sinks. The total value of forest carbon sinks in 2003 and 2008 was RMB 26.73×10^9 yuan and RMB 29.77×10^9 yuan, respectively, with an average annual growth of 2.18 %. From 2003 to 2008, both stock and flow value of forest carbon sinks increased, but the total net flow value of carbon sinks decreased. The growth rate for the environmentally adjusted Gross Domestic Product (eaGDP) for China's forest carbon sinks was 17.23 %, outstripping the average growth rate of 9.5 % for the GDP during the same period. The study alsoindicates that China's forest carbon sinks affects the GDP in the range of 0.25-0.26 %, and its economic potential is not relatively huge. 展开更多

Links between institutional sectors and economic activities with National Accounting System of Mexico are studied used accounting multipliers. Key sectors had changed to strategic or leading as oil and gas extraction and dairy product manufacturing, i.e., Mexico went from a producer of goods to a service provider country, losing value added in their production chains. The mixed income is leading/independent economic activity for woman whose income is between 1 and 5 minimum wages. This is really important in the domestic economy through its impact on solidarity activities: providing care and support and providing food. Moreover, non-financial corporations and households of 10 or more minimum wages for income investing in strategic sectors such as retail trade and wholesale and manufacturing products derived from oil and coal. This is evidence of two Mexicos: the traditional and industrialized. 展开更多

With common borders of the population, total area, and GDP (PPP-based) of Economic Cooperation Organization (ECO) member states are estimated as 416 million persons, 7.9 million m2, and US$2.7 trillion respectively (2010 data). Although heterogeneous in the extent, there is economic development, overall, with serious energy and transport-transit relations among countries that is reflected in growing trade turnover year-by-year. However, there are still rather unused resources and capacity in such areas of cooperation among countries as exchange of energy, transport services, agricultural and industrial goods, use of opportunities for tourism, promoting investment and innovation processes and other areas. Certainly, maximum and optimal use of these resources calls for availability of analytical means capable of accounting for relations both within member states and among them. The implementation of computable general equilibrium (CGE) modeling in each member state would thus be of great significance in resolution of these problems both in terms of accounting for input-output linkages within the countries as well as enabling impact of main trading partners and goods and services among countries. The analysis carried out indicates that there are a number of problems in application of CGE model in most of the member states. As such, input-output tables are not compiled in some countries, while in others despite the fact that these tables are compiled, there are no attempts to build the model, yet in other countries, even if the CGE model is implemented, there are difficulties in taking into account the real results in the face of serious problems related to improving national accounts system database. Summarizing these problems, it is possible to conclude that to ensure the application of a CGE model,there is a great need to work out procedures of compilation of a social accounts matrix (SAM) that lies on the basis of this model, for which the relevant statistics of a member state must be improved. Considering the above-mentioned, the presented research, makes procedures and proposals on compilation of SAM, improves statistical data for researching the extent of application of CGE Model in ECO member states, and identifies the degree of availability and organization of relevant data to develop input-output tables and respective SAM. 展开更多

There is a broad acceptance to depicting the relationship between ecosystems and human well-being using the concept of ecosystem services,emanating in large from the findings and research published in the Millennium Ecosystem Assessment in 2005.While the generic concept of ecosystem services provides an excellent platform for discussion,the ongoing lack of clarity surrounding the definition,clas sification and measurement of ecosystem services,is emerging as a barrier to more extensive collaboration across disciplines.This paper applies the principles of national accounting to bring additional rigor and consistency to the discussion on ecosystem services.In this paper we revisit four fundamental aspects of the System of National Accounts(SNA)that underpin the measurement of the economy,namely,the definition of economic units;the definition of production;the recording of transactions and the recording assets.By considering each of these aspects in the context of the United Nations'System of Environmental-Economic Accounting,the paper presents a framework to describe the relationship between ecosystems and human aativity that can then be used to consistently define,classify,measure and account for ecosystem services. 展开更多

The creation of China's National Parks and Protected Areas System is at a critical stage,and it is imperative to discuss the long-term target for China's protected areas coverage.In other words,how much of the national land area should be dedicated to or used for nature conservation,can it truly protect species and their habitats,and can it provide essential ecosystem services for the sustainable development of China's economy and society?1 Why Study the Long-term Target of Protected Area Coverage in China?The biodiversity crisis has become one of the biggest challenges faced by all countries in the world.China's rate of species extinction and ecosystem degradation are also a cause for concern.One of the most effective measures to deal with these crises is to establish an efficient and effective protected area network[1-4]. 展开更多

Karst aquifers occur worldwide and exhibit groundwater flow responses that differ considerably from aquifers lacking fractures, bedding planes, and other karst conduits where significant and rapid groundwater flow can occur. The regional, karst Floridan aquifer system underlies the United States (US) Southeastern Coastal Plain Physiographic Region and exhibits hydrologic interconnections with overlying surficial aquifers and throughout other zones of the aquifer system, as is characteristic of other karst aquifer systems. Anthropogenic groundwater declines in this regional karst aquifer system have been documented in published literature for decades, but the impacts of those declines in this coastal plain region and the embedded ecosystems that provide essential and critical habitat for native, endemic, and federally endangered and threatened species have not been considered previously. Those anthropogenic groundwater declines reduce surfacewater levels and flows due to the capture of both groundwater and overland flow of surfacewater, resulting in induced recharge through semi-confining zones and interbasin flow through fractures and other karst conduits. This case study identifies examples from the Greater Okefenokee Swamp Basin study area and comparison areas of how those declines result in loss of historic base flow to surface waters and other capture of surface waters, ultimately increasing saltwater intrusion. Those results alter and degrade the physical, chemical, and biological integrity of the nation’s waters, in violation of the US Clean Water Act (CWA) of 1972. Historic groundwater declines from mining and other anthropogenic groundwater withdrawals from this regional karst aquifer system already threaten the survival and recovery of federally endangered and threatened species, as well as existing and proposed critical habitat for those species within this regional extent, in violation of the Endangered Species Act (ESA) of 1973. This case study and its companion publication (Part 2) appear to be the first to provide scientific support for this regional karst aquifer system as the unifying factor in habitat responses to irreversible groundwater impacts on aquatic and marine ecosystems. These adverse impacts strongly suggest that the extent of the regional Floridan aquifer system should be designated as the Southeastern Coastal Plain Ecoregion for the purpose of managing natural resources. Mining activities continue to expand in our study area, which is the Greater Okefenokee Swamp Basin. Despite that fact, no comprehensive Areawide Environmental Impact Statement (AEIS), similar to the AEIS required for phosphate mining within the Central Florida Phosphate District (CFPD) approximately a decade ago has been conducted for any of the numerous mining projects that are occurring and are proposed within the Greater Okefenokee Swamp Basin. This case study also provides examples of why a comprehensive AEIS is essential to consider all of the adverse direct, indirect, and cumulative impacts of those mining activities to the CWA, the ESA, and the irreversible losses to local economies, because federal agencies responsible for considering those adverse impacts rely on public comments to identify those adverse impacts. The mining activities authorized throughout the regional Floridan aquifer system under Category 44 Nationwide Permits (NWP) result in the same type of adverse impacts as the mining activities evaluated under Individual Permits in that region. Therefore, those Category 44 NWP mining activities also should be required to obtain Individual Permits and be evaluated under an AEIS in the Greater Okefenokee Swamp Basin. This case study also describes how Florida’s assumption of the CWA Section 404 regulatory authority in 2020 severs four sub-basins within the Greater Okefenokee Swamp Basin study area at the state line between Florida and Georgia. 展开更多

As China has embarked on a new journey to comprehensively build a modern socialist country and marches toward the Second Centenary Goal,improving the protection of human rights in environmental protection has become a key task to meet people's growing demand for a better life.The international community has reached a consensus on the human rights attribute of environmental rights,and China has also recognized it in its National Human Rights Action Plan of China(2021-2025).Early claims for environmental human rights gave birth to modern environmental law at the international level,while the global consensus on sustainable development promoted the new development of environmental human rights.In China,the construction of a"beautiful China"has become the national goal confirmed by the Constitution.The confirmation of environmental rights in the planned environmental code can further clarify the connotation of the value system of the code and help clarify the institutional structure and attribution logic of the code.Based on the subjective right and objective value of environmental rights,the specific scheme for the"codification"of environment rights is to construct the system from three levels of ontological provision,guarantee provision and reliefprovision. 展开更多

The major statistical difference between the Chinese and U.S.savings rates is that the United States adopts the conceptof a net savings rate, while China adopts the concept of gross savings rate in which savings include asset depreciation.Despite the different statistical calculations, we can come to the following conclusions: i) the savings rate in China hasbeen rising and that of the United States has been falling; ii) the savings rate in China is high and that of the UnitedStates is low; and iii) the household savings rate in China is high and the personal savings rate of the United States islow.The gap between China and the United States’ savings levels reflects residents’ loss of a sense of security, an absenceof enterprises’ social obligations and the enhancement of the government’s power over the whole economy during theprocess of institutional reform in China.Hence, while firmly promoting social-security system reform and advancingnational income allocation system reform, it is of significance in the long term for China to restrain enterprises’ andgovernment’s allocation behaviors and prevent public department interests from being solidified. 展开更多
