Water
Paragraphs

As water becomes scarcer in northern China, designing policies that can induce water users to save water has become one of the most important tasks facing China's leader. Past water policies may not be a solution for the water scarcity problem in the long run. This paper looks at a new water policy: increasing water prices so as to provide water users with direct incentives to save water. Using a methodology that allows us to incorporate the resource constraints, we are able to recover the true price of water with a set of plot level data. Our results show that farmers are quite responsive if the correct price signal is used, unlike estimates of price elasticities that are based on traditional methods. Our estimation results show that water is severely under priced in our sample areas in China. As a result, water users are not likely to respond to increases in water prices. Thus as the first step to establishing an effective water pricing policy, policy makers must increase water price to the level of VMP so that water price reflects the true value of water, the correct price signal. Increases in water prices once they are set at the level of VMP, however, can lead to significant water savings. However, our analysis also shows that higher water prices also affect other aspects of the rural sector. Higher irrigation costs will lower the production of all crops, in general, and that of grain crops, in particular. Furthermore, when facing higher irrigation costs, households suffer income losses. Crop income distribution also worsens with increases in water prices.

In summary, our paper provides both good news and bad news to policy makers. On the one hand, water pricing policies obviously have great potential for curbing demand and helping policy makers address the emerging water crisis. On the other hand, dealing with the negative production and income impacts of higher irrigation cost will pose a number of challenges to policy makers. In other words, if China's leaders plan to increase water prices to address the nation's water crisis, an integrated package of policies will be needed to achieve water savings without hurting rural incomes or national food security.

This project involves political scientists, economists, and medical researchers to address the question of whether hunger, poverty, disease and agricultural resource constraints foster civil conflict and international terrorism. Economists have elucidated the links between agricultural stagnation, poverty, and food insecurity, and political scientists have empirically analyzed the role of poverty in facilitating civil conflict.

Paragraphs

Water scarcity is one of the key problems that affect northern China, an area that covers 40 percent of the nation's cultivated area and houses almost half of the population. The water availability per capita in North China is only around 300 m3 per capita, which is less than one seventh of the national average. At the same time, expanding irrigated cultivated area, the rapidly growing industrial sector and an increasingly wealthy urban population demand rising volumes of water. As a result, groundwater resources are diminishing in large areas of northern China. For example, between 1958 and 1998, groundwater levels in the Hai River Basin fell by up to 50 meters in some shallow aquifers and by more than 95 meters in some deep aquifers.

Past water policies have not been effective in solving water scarcity problems. China's leaders have put priorities on increasing water supply through developing more canal networks or building more reservoirs. In 2001, the State Council started the South-to-North Water Transfer Project. However, these supply-side approaches cannot meet the increasing demand for water from all of the different sectors and cannot solve water scarcity problems in the long run.

Paragraphs

In a book assessing the development of China during the People's Republic era, it is of interest to know how well agriculture has performed and the role that it has played in the development process. Has China produced food and other commodities that have contributed to China's growth? Has it been successful supplying labor to the off farm sector? How has agriculture contributed to the rise in rural incomes and growth, in general? In short, one of the overall goals of this chapter is to document the performance of the agricultural sector and use the criteria of Johnston and Mellor to assess how well the agricultural sector has done.

This chapter, however, seeks to go further than describing the achievements and shortfalls of China's agricultural economy; we also aim to identify the factors, both domestic policies and economic events as well as foreign initiatives, that have induced the performance that we observe. To create an agricultural economy that can feed the population, supply industry with labor and raw materials, earn foreign exchange and produce income for those the live and work in the sector and allow them to be a part of the nation's structural transformation requires a combination of massive investments and well-managed policy effort. The process can only proceed smoothly if an environment is created within which producers can generate output efficiently and earn a profit that can contribute to household income. Policies are required to facilitate the development of markets or other effective institutions of exchange. Although the sector is expected to contribute to the nation's development and allow for substantial extractions of labor and other resources, large volumes of investment also are needed. Investment in education, training, health and social services are needed to increase the productivity of the labor force when they arrive in the factories. Investment is needed in agriculture to improve productivity to keep food prices low, allow farmers to adopt new technologies and farming practice as markets change, and to raise incomes of those that are still in farming. Investment is needed in technology, land, water and other key inputs that are in short supply. In this chapter we seek to point out both policies that have facilitated the performance of the agricultural sector and those that have constrained it.

Soybean production has become a significant force for economic development in Brazil, but has come at the cost of expansion into non-protected forests in the Amazon and native savanna in the Cerrado. Over the past fifty years, production has increased from 26 million to 260 million tons. Area planted to soybeans has increased from roughly 1 million hectares in 1970 to more than 23 million hectares in 2010, second only to the United States.

Paragraphs

Public services provision in the developing world, including China, is crucial for rural development and poverty reduction. Although there has been much effort focused on public goods investment in China in recent years, there are still great differences among villages in the level of public goods investment. This study seeks to explain these differences by focusing on the effect of community governance on public goods provision at the village level, including investment into roads, water control and schools. During the recent past several years, village governance in rural China has undergone a series of fundamental reforms. Arguably, the advent of direct elections for village leaders and the rural Tax for Fee Reforms are two of the most important shifts in the ways that communities manage themselves. Using a nearly nationally representative sample of communities from survey data that includes information from more than 2400 villages in rural China, we find that the direct election of a villages leader leads to increased public goods investment in the village. The paper also demonstrates that the rural Tax for Fee Reforms, ceteris paribus, has a negative effect on public goods, especially on investment by the village itself.

Climate shocks leading to floods and droughts present high levels of uncertainty and difficulties in decision making for water district managers, agricultural producers, and policymakers throughout the world. This project focuses on the impacts of El Nino-Southern Oscillation (ENSO) events on precipitation and temperature variability, and in turn on water management and crop production, in one of China's major rice bowls, Jiangxi Province. Jiangxi is also one of China's poorest provinces, where swings in crop production and prices can jeopardize rural incomes and food security.

Paragraphs

The overall goal of the paper is to better understand the development of groundwater markets in northern China. In particular, this paper focuses on the factors that determine the development of groundwater markets in the attempt to explain their "breadth" (the share of villages in which there are groundwater market activity) and "depth" (the share of water which the average tubewell owner sells to others on a market basis). Based on a survey of 24 randomly sampled villages and 50 randomly sampled tubewells in two provinces (Hebei and Henan Province) in 2001 and a field survey of 68 randomly sampled villages in 4 provinces (Hebei, Henan, Shanxi, and Shaanxi) of northern China in 2004, research results show that groundwater markets in northern China have emerged and are developing rapidly. Groundwater markets in northern China also are shown to be informal and localized and developing in a number of ways that make them appear somewhat similar to markets that are found in South Asia. However, groundwater markets in northern China also differ from those in South Asia in other ways, water sales in China are almost all impersonal and they almost always work on a spot-market, cash bases (that is, there is no price discrimination and there are no share or labor sharing arrangements as are sometimes found in South Asia). Econometric results show that the privatization of tubewells is one of the most important driving factors that encourage the development of groundwater markets. Increasing water and land scarcity and policy interventions also are important determinants that induce the development of groundwater markets.
