“…The requirements for (and economics of) water distribution are much studied. Saving and recycling water for ecological purposes (Chen 1995;Baird and Wilby 1999;Cheng 2002aCheng , 2002b, water technology (Loschel 2002), water-related macro-and microeconomics (Roger et al 1993;Wang et al 2000), ecological protection with least economic cost (Yang et al 2003) and policy games (Slobadan and Hussan 1999;Hamilton et al 2002), have all been investigated in recent years. Although pricing and marketing are currently the main focus in water distribution, an efficient economic system can result from pricing policy only when there is sufficient free competition.…”

Areas of water shortage comprise many smaller sub-areas into which water is transported from external sources. Fairness and efficiency of distribution are overriding principles. Each local area requires adequate water for community and ecological purposes as well as a supply sufficient to maximise economic growth. Within arid and semi-arid areas, there are conflicts between the sub-areas and between these three types of water use, which can erupt into violent confrontations between different user groups. This study has developed a dynamic model for equitable distribution of water in water-shortage areas and aims to optimally satisfy the requirements of each locality, given limited supplies, and to maximise the total economic benefit of the entire area. The Heihe River Basin in northwest China was chosen as the area for the pilot study.

“…In the last decade, an increasing number of studies have contributed to the knowledge of allocating the limited water resources among different ecosystems in river basins to balance the economic development and environmental sustainability . However, most of these studies were carried out within a short time range, either to identify the rationality of water allocation scheme reform (Cheng, 2002;Yang et al, 2003) or to test the effectiveness of ecological restoration projects (Thevs et al, 2015). Long-term change study in vegetation systems in response to significant alterations in climate, hydrology, and social-economic conditions is lacking in the current literature (Sivapalan et al, 2012).…”

Abstract. The response of vegetation systems to the longterm changes in climate, hydrology, and social-economic conditions in river basins is critical for sustainable river basin management. This study aims to investigate the evolution of natural and crop vegetation systems in the Heihe River basin (HRB) over the past 2000 years. Archived Landsat images, historical land use maps and hydrological records were introduced to derive the long-term spatial distribution of natural and crop vegetation and the corresponding biomass levels. The major findings are that (1) both natural and crop vegetation experienced three development stages: a pre-development stage (before the Republic of China), a rapid development stage (Republic of China -2000), and a post-development stage (after 2000). Climate and hydrological conditions did not show significant impacts over crop vegetation, while streamflow presented synchronous changes with natural vegetation in the first stage. For the second stage, warmer temperature and increasing streamflow were found to be important factors for the increase in both natural and crop vegetation in the middle reaches of the HRB. For the third stage, positive climate and hydrological conditions, together with policy interventions, supported the overall vegetation increase in both the middle and lower HRB; (2) there was a significantly faster increase in crop biomass than that of native vegetation since 1949, which could be explained by the technological development; and (3) the ratio of natural vegetation to crop vegetation decreased from 16 during the Yuan Dynasty to about 2.2 since 2005. This ratio reflects the reaction of land and water development to a changing climate and altering social-economic conditions at the river basin level; therefore, it could be used as an indicator of water and land management at river basins.

“…The framework determines a costeffective land retirement pattern to reduce off-site sediment loadings from fields in the United States, where the retirement of cropland is one of measures against the agricultural nonpoint pollution. Yang et al (2003) developed an integrated economic, environmental, and GIS modeling framework as an extension of the study by Khanna et al (2003) and applied it to compare cost, acreage, location, and land parcel differences between a non-uniform and uniform standard across 12 sub-watersheds in the Illinois River Basin in the United States. Moxey and White (1994) evaluated several nitrate abatement policy instruments from a cost-effectiveness standpoint using an aggregate linear programming model to approximate producers' choice of land covers and management practices.…”

“…Moxey and White (1994) evaluated several nitrate abatement policy instruments from a cost-effectiveness standpoint using an aggregate linear programming model to approximate producers' choice of land covers and management practices. Although studies by Khanna et al (2003) and Yang et al (2003) treat both economic and environmental issues in optimization considering physical pollutant transport in a large area, they are not applicable to a decision-making on crop diversification in paddy fields that are consolidated in relatively small low-land areas in Japan.…”

An optimization model for cropping-plan placement on field plots is presented for supporting decision-making on agricultural management by a farming organization. The mixed 0-1 programming technique is employed to select the next planting crop at each field plot in a holistic manner. Reduction of total nitrogen discharged from field plots to the downstream end of the drainage canals is expressed as an objective function of the model to balance an achievement of economic goal and environmental conservation. Some Japanese governmental policies on regulating rice cropping areas and on promoting production of particular upland field crops can be formulated in the model. A computational example of cropping-plan placement on field plots managed under integrated policies is given by operating the optimization model with various weights associated with the objectives. The procured tradeoff curve and corresponding patterns of cropping-plan could be useful in the decision-making by the farming organization.
