<p>Global food trade entails virtual flows of agricultural resources and pollution across countries. Here we performed a global-scale assessment of impacts of international food trade on blue water use, total water use, and nitrogen (N) inputs and on N losses in maize, rice, and wheat production. We simulated baseline conditions for the year 2000 and explored the impacts of an agricultural intensification scenario, in which low-input countries increase N and irrigation inputs to a greater extent than high-input countries. We combined a crop model with the Global Trade Analysis Project model. Results show that food exports generally occurred from regions with lower water and N use intensities, defined here as water and N uses in relation to crop yields, to regions with higher resources use intensities. Globally, food trade thus conserved a large amount of water resources and N applications, and also substantially reduced N losses. The trade-related conservation in blue water use reached 85 km<sup>3</sup> y<sup>−1</sup>, accounting for more than half of total blue water use for producing the three crops. Food exported from the USA contributed the largest proportion of global water and N conservation as well as N loss reduction, but also led to substantial export-associated N losses in the country itself. Under the intensification scenario, the converging water and N use intensities across countries result in a more balanced world; crop trade will generally decrease, and global water resources conservation and N pollution reduction associated with the trade will reduce accordingly. The study provides useful information to understand the implications of agricultural intensification for international crop trade, crop water use and N pollution patterns in the world.</p>

This study aims to: (1) determine the conservation of water resources willingness to pay (WTP) of the community, (2) determine the determinants that significantly affect the value of PAPs for additional benefits due to increase management of water resources conservation, and (3) determine whether reforestation environment is a type of conservation that community desires. Respondents from this study are Surakarta citizens, precisely in the southern region of Surakarta, Laweyan District, Central Java. They are customers of Surakarta Municipal Water Supply Company, especially the water distribution of the Cokro Tulung spring. This study uses linear analysis and Contingent Valuation Method (CVM). The interviews result with 106 respondents revealed that: (1) the average value of WTP in R2 is Rp 1,872,-, the average value of WTP in R3 is Rp 3,238,-, the average value of WTP in R4 is Rp 2,769,-, and the average value of WTP in trade group 1 is Rp 3,846,-, (2) education variables and perception variables on the importance of conservation have a significant effect on WTP of conservation of water resources, and (3) survey results show that there are 73.6% of respondents intend to do greening around Cokro Tulung spring.

Conservation Cost

Ecological compensation is being applied to deal with transboundary external effects caused by water resources conservation or exploitation in China. A concept of water resources co-conservation and sharing was applied to burden the upstream conservation cost and to share the benefit in the whole river basin. Xin’an River Basin, related to two provinces in East China, was taken as the study area. The current territorial scales of the co-conservation area and the benefit sharing area were determined. The total actual water conservation cost for Xin’an River Basin was estimated to be about 488 million CNY in 2006. By analyzing the transformation of protection costs and benefits between different districts and sections, benefits brought by water to different beneficiaries were also estimated. The conservation cost was distributed to the water users or governments in the whole sharing area according to the proportion of shared benefits.
