INTERSTATE AND INTERNATIONAL AQUIFERS1

Many important groundwater aquifers cross state and national boundaries. The flow of water in these aquifers is not influenced by the boundaries but may be materially influenced by mans activities on one or both sides of a boundary. Interstate and international problems may develop because of excessive groundwater lowering on one side of a boundary affecting water users on the opposite side of the line. Similarly, intensive groundwater development along a surface stream may influence the amount of surface water that flows across a boundary. A third type of problem may develop when pumping on one side of the boundary induces poor quality water into an aquifer on the other side of the boundary. Several specific interstate and international aquifer problems are briefly described.

HYDROELECTRIC POWER AND SCENIC PROVISIONS OF THE 1950 NIAGARA TREATY1

ABSTRACT: An important international Niagara River management issue concerns allocation of the average 202,000 cubic feet per second river discharge for hydroelectric power and scenic purposes. Major water diversions from Niagara Falls are necessary for power production. Flow is allocated by the 1950 Niagara Treaty which is intended to maximize power benefits and preserve and enhance the scenic fals spectacle. This paper examines the extent to which the Treaty objectives have been achieved. Based on analyses of government documents, engineering data, and falls-viewing patterns, it is concluded that the 1950 Treaty led to enhancement of the falls spectacle and increased power generation. But significant additional power diversions probably are attainable without adverse effect upon the existing falls spectacle. Reducing daytime summer Horseshoe Falls flow and scheduling spring and autumn flow according to viewing patterns are possible means of increasing power diversions. Existing generating facilities could use considerably more water and the value of additional Niagara hydroelectricity is very high in terms of generation-cost savings over alternative power sources. Because of the cultural importance of the falls, Treaty modifications to permit increased power diversions are not recommended without prior public opinion sampling and on-site viewing experiments. These findings highlight the need for more careful study before long-term international agreements are concluded and illustrate the need for more flexible treaty arrangements to permit periodic adjustments for changing conditions.

Two solitudes: post‐tsunami and post‐conflict Aceh

In August 2005, after the devastating tsunami in the Indian Ocean Basin, a Memorandum of Understanding (MoU) for the cessation of hostilities was signed by Aceh's longstanding adversaries—the Government of Indonesia and the Free Aceh Movement (GAM). The tsunami was a major catalyst for ‘disaster diplomacy’—international political pressure, which, this paper argues, was an important ingredient in creating conditions for the MoU, although the situation within Aceh also shaped the peace process. Based on interviews conducted in 2006 and 2007 with government officials, GAM representatives and fighters, and non‐governmental organization staff in Aceh, this paper finds that assistance for tsunami survivors far exceeds that available for conflict survivors and ex‐combatants. The formation of these two solitudes—the tsunami‐affected and the conflict‐affected—compounds challenges for sustaining peace in Aceh. This research points to an enduring lack of livelihoods for former fighters and conflict victims that may threaten a sustainable peace.     

Emerging market patterns in the recycled paper trade

The international recovered paper trade serves two important functions: increasing raw material availability in the paper and board industry and providing economic incentives to recycle. The purpose of this paper is to shed further light on emerging patterns in this trade by empirically analysing the changes in the bilateral trade flows of recycled paper between 1992 and 2008. According to our estimations, two important changes occurred in the 1990s and 2000s. First, the growing importance of developing economies in global recycled paper trade plays a significant role in import demand as a determinant of trade flows. Second, the changes in global trade patterns necessitate investigating the transportation cost measures used in applied research.     

International trade,carbon leakage,and CO2 emissions of manufacturing industry

Foreign trade drives China’s growth,but as the trade scale continues to expand,the carbon emissions also increase quickly.Based on the industry panel data from 1996 to 2010,this paper calculates carbon emissions of 27manufacturing industries.According to the intensity of carbon emissions,this paper divides the manufacturing sectors into low carbon and high carbon manufacturing industry and then analyzes the carbon emission trends.Next,the paper uses the feasible generalized least square regression to verify the existence of environmental Kuznets curve（EKC）of the manufacturing industry’s carbon.In order to investigate the carbon leakage problem,the regression also includes the interaction term between trade and industrial value added.Our findings are as follows:the carbon emissions of the whole manufacturing industry and low carbon manufacturing industry accord with the EKC curve,but have a linear relationship with the high carbon manufacturing industry;trade reduces the carbon emissions of the whole manufacturing industry and low carbon manufacturing industry,but it increases those of the high carbon manufacturing industry;for the whole manufacturing industry and low carbon manufacturing industry,there is no carbon leakage,but it exists in the high carbon manufacturing industry.On the whole,pollution haven hypothesis does not hold up in China,and China does not need to limit industry foreign trade to reduce the emission of CO₂.But the manufacturing industry will still be the main engine of the economic growth,and therefore our country should make an effective low-carbon policy,introduce advanced technology,increase R&D investment into lowcarbon technologies,and upgrade and transform the original equipment to change the backward mode of production.

国际粮食贸易影响下东北黑土地生产压力变化与保护策略

黑土地是重要的农产品生产基地之一,承担着保障国家粮食安全和维护农业生态安全的重要责任,保护好黑土地对促进我国农业可持续发展至关重要。测算与分析2000—2020年东北黑土地粮食生产耕地压力的变化情况,研究国际贸易对东北黑土地粮食生产的耕地压力的影响,利用国际市场占有率指数和贸易竞争优势指数分析东北黑土地农产品在国内及国际两个市场的竞争优势。结果表明：近20年来东北黑土地粮食生产的耕地压力基本处于安全压力区并呈逐步下降的趋势,玉米、大豆、稻谷三种主要作物生产的耕地压力分别从2000年的1.94、1.09和0.63下降至2020年的0.69、0.26和0.54。国际粮食贸易对黑土地粮食生产耕地压力减缓的作用显著且呈现出逐年上升的趋势,2020年对黑土地粮食生产耕地压力减缓的贡献率达26.22%,其中对大豆生产的耕地压力减缓的贡献率达511.48%。农产品贸易优势度分析结果显示,东北黑土地农产品在国内市场具有明显的贸易竞争优势,但在国际贸易中的竞争优势不明显。为此,提出了国际贸易粮食贸易变化背景下黑土地保护的若干建议,为东北黑土地保护及其粮食产能保障相关决策提供参考。
