Adoption and Impacts of Zero-Tillage in the Rice-Wheat Zone of Irrigated Punjab, Pakistan AgEcon
Farooq, Umar; Sharif, Muhammad; Erenstein, Olaf.
This study documents the adoption and impacts of zero-tillage (ZT) wheat in the ricewheat systems of Pakistan’s Punjab province primarily drawing on a detailed empirical survey of 458 rice-wheat farmers. Our random stratified sample revealed 19% to be ZT wheat adopters and a similar share of the wheat area in the surveyed communities to be under ZT. The study suggests that diffusion has stagnated and also flags the issue of disadoption (14%). ZT adopters, non-adopters, and disadopters differ significantly in terms of their resource bases, with adopters typically showing the most favorable values. ZT drastically reduces tractor operations in farmers’ ZT wheat fields from an average of 8 passes to a single pass, implying a saving of 7 tractor hours and 35...

Is the Green Revolution Vanishing? Empirical Evidence from TFP Analysis for Rice AgEcon
Adlas, J.; Achoth, Lalith.
A serious concern has been raised recently on the long run sustainability of the productivity effects of Green Revolution technologies in the light of decelerating trend in the yield growth of rice since the mid 1980s under irrigated ecosystem. However, the changes in physical yield are not true measures of productivity from efficiency perspective. Total factor productivity (TFP) is a true measure of economic efficiency of any technology impact. The paper addresses the crucial issue of "is green revolution vanishing" empirically by analyzing TFP for rice in India. Results suggest that various modern technologies (such as modern cultivars) adopted by the farmers over the period have continued to make considerable impact on rice productivity growth-as...

Partial Reform of World Rice Trade: Implications for the U.S. Rice Sector AgEcon
Haley, Stephen L..
This paper analyzes the consequences for the United States of a partial reform of world rice trade. It is argued that likely trade reform would occur in the japonica rice producing countries of Japan, South Korea, Taiwan, and the European Community. Multilateral rice trade liberalization would have strong effects for medium grain rice in the United States. The strength of these effects might not be felt for a couple of years after the liberalization has begun because of minimal Japanese imports in the first couple of years of liberalization. U.S. rice millers will likely benefit more than producers. California producers would be the major beneficiaries of more open world rice markets.

Assessing Korean Consumers’ Valuation for Domestic and Imported Rice: Importance of Country of Origin and Food Miles Information AgEcon
Han, Doo Bong; Nayga, Rodolfo M., Jr.; Lee, Ji Yong; Yoon, Jong Min.
The aim of this paper is to determine Korean consumers’ valuation for domestic rice and imported rice from China and the US. Using revealed preference data from random nth price auction mechanism, our results generally suggest that consumers’ willingness to pay (WTP) for domestic rice is higher than the WTP for imported rice. Results also suggest that while country of origin and food miles information positively influences consumers’ WTP for domestic rice, country of origin information provides higher valuation for domestic rice than food miles information. Country of origin and food miles information has no statistically significant effect on WTP for the imported Chinese rice product but food miles information has a negative effect on WTP for the imported...

Updated Arkansas Global Rice Model AgEcon
Wailes, Eric J.; Chavez, Eddie C..
The Arkansas Global Rice Model is based on a multi-country statistical simulation and econometric framework. The model consists of six sub regions. These regions are the U.S., South Asia, North Asia and the Middle East, the Americas, Africa and Europe. Each region comprises of several countries and each country model has a supply sector, a demand sector, a trade, stocks and price linkage equations. All equations used in this model were estimated using econometric procedures or identities. Estimates are based upon a set of explanatory variables including exogenous macroeconomic factors such as income, population, inflation rate, technology development, and especially, government determined policy variables which reflect the various mechanisms by which...

Analyzing Market Price Transmission, Government Intervention and Weather Shocks for Rice Market in the Philippines AgEcon
Jolejole-Foreman, Maria Christina; Mallory, Mindy L..
In the Philippines, where rice is considered the most important food crop, attempts to influence rice prices have been prevalent. The government, through National Food Authority (NFA) has sought to establish stocks and control imports to stabilize prices since its establishment in 1972 to support farm gate prices and reduce retail price of rice. But data shows divergence in retail prices and farm prices since mid 1960s. In this paper, we use vector autoregression (VAR) to analyze the movement of Philippine rice margins with government stocks and weather supply shocks to able to determine government effectiveness in actual times of market stress. Comparing VARs across regions, we are able to identify the regions in which price margins are significantly...

Decoupled Payments and Agricultural Policy Reform in Korea AgEcon
Lim, Song-Soo.
Abolishing a nearly 50-year-old policy for rice price support, Korea adopted a new direct payment program in 2005. Making the transition to decoupled income payments has been governed by the need for operative and effective income safety nets and the WTO disciplines on domestic support. The program aims to deal with over-supply of rice while guarding against the threat of income insecurity. Integrated into a target price mechanism, the fixed and variable payments compensate part of farm income loss arising from adverse market conditions. Besides, the government launched a public stockholding measure to ensure food security. A review of previous studies highlights the fixed payment has no or at most minimal effects on production while the variable payment...

Analysis of Participation in Multifunctional Agriculture: U.S. Rice Farms AgEcon
Tur Cardona, Juan; Wailes, Eric J.; Dixon, Bruce L.; Danforth, Diana M..
Multifunctional agriculture is particularly fundamental to some working lands conservation policies and programs, such as the Environmental Quality Incentive Program (EQIP), Conservation Security Program (CSP) and Wildlife Habitat Incentive Program (WHIP). Farmers can also be engaged in providing recreational and agri-tourism services such as hunting, fishing, bird-watching, farm tours, petting zoos and hospitality services. Using the Agricultural Resource Management Survey (ARMS) we analyze factors associated with participation in conservation, recreation and agri-tourism activities as a function of farm structure, farm financial measures, production practices, and socio-demographic characteristics of the farm operator. To estimate the functional...

COMPARATIVE ANALYSIS OF THE IMPACT OF LABOR OUT MIGRATION AND REMITTANCES ON INCOME AND RICE PRODUCTIVITY IN THE PHILIPPINES, THAILAND AND VIETNAM AgEcon
Paris, Thelma R.; Rola-Rubzen, Maria Fay; Luis, Joyce; Thi Ngoc Chi, Truong; Wongsanum, Chaicharn; Villanueva, Donald.
Out migration from rural areas is increasingly becoming a strategy to get out of poverty. While rice–based agriculture remains to be the backbone in Southeast Asia, majority of the farming households particularly those who produce rice under rainfed conditions remain poor and insecure. This paper examines the relationship between migration and other socio-economic factors on household income using data from 1,874 rice sample farming households in Vietnam (north and south), Thailand (northeast) and Philippines (Luzon island). In the Philippines, remittances contribute about 60 per cent of household income of recipient families. In Thailand and Vietnam, these constitute about 40 per cent of total household income. International migration is most prevalent in...

Adoption of New Seed Varieties Under Production Risk: An Application to Rice in Iran AgEcon
Bakhshoodeh, Mohamad; Shajari, S..
This paper focuses on linkage between new rice seed varieties and production risk and also factors affecting adoption of these varieties in Iran. Farm-level data were collected from a sample of 154 rice farms located in two major districts of Fars province in Southern Iran for 2001-02. The risk-premium associated with the use of seed is estimated following by analyzing a moment-based production risk approach. The results show that the risk premium increases with new seed varieties in the lack of appropriate production conditions implying that new seed varieties is a riskincreasing input and involves a higher cost of risk. However, under suitable production conditions, the cultivation of new rice varieties on average ensures greater yield and at the same...

Adoption and impacts of zero tillage as a resource conserving technology in the irrigated plains of South Asia AgEcon
Erenstein, Olaf; Farooq, Umar; Malik, R.K.; Sharif, Muhammad.
The recent stagnation of productivity growth in the irrigated areas of the Indo-Gangetic Plains of South Asia has led to a quest for resource-conserving technologies that can save water, reduce production costs and improve production. The present synthesis of two detailed country studies confirmed widespread adoption of zero tillage (ZT) wheat in the rice-wheat systems of India’s Haryana State (34.5% of surveyed households) and Pakistan’s Punjab province (19%). The combination of a significant “yield effect” and “cost-saving effect” makes adoption worthwhile and is the main driver behind the rapid spread and widespread acceptance of ZT in Haryana, India. In Punjab, Pakistan, adoption is driven by the significant ZT-induced cost savings for wheat...

Indian Wheat and Rice Sector Policies and the Implications of Reform AgEcon
Landes, Maurice R.; Jha, Shikha; Srinivasan, P.V..
During 1998-2002, India experienced record public surpluses of wheat and rice, sharply higher government grain subsidy outlays, and declining per capita consumption of wheat and rice. By 2006, despite continued high subsidies and sluggish domestic consumption, India developed a large wheat deficit because of reduced price incentives, weak yield growth, and rising subsidized consumption. The pronounced market cycles and declining per capita consumption for India’s major food staples are creating pressure for Indian policymakers to adjust longstanding policies. While there has been no political consensus on more fundamental reform, recent policy changes have moved toward better targeting of food subsidies to low-income consumers, decentralization of...

INTERNATIONAL AND INSTITUTIONAL R&D SPILLOVERS: ATTRIBUTION OF BENEFITS AMONG SOURCES FOR BRAZIL'S NEW CROP VARIETIES AgEcon
Alston, Julian M.; Pardey, Philip G.; Chan-Kang, Connie; Magalhaes, Eduardo Castelo; Vosti, Stephen A..
In general, reported rates of return to agricultural R&D are high, but questions have been raised about upward biases in the evidence. Among the reasons for this bias, insufficient attention to attribution aspects-matching of research benefits and costs-is a pervasive problem, the magnitude of which is illustrated here with new evidence for Brazil. Over the period 1981 to 2003, varietal improvements in upland rice, edible beans, and soybeans yielded benefits attributable to research of $14.8 billion in present value (1999 prices) terms; 6.1 percent of the corresponding value of crop output. If all of those benefits were attributed to Embrapa, a public research corporation accounting for more than half Brazil's agricultural R&D spending, the...

Global Market Shocks and Poverty in Vietnam: The Case of Rice AgEcon
Coxhead, Ian A.; Linh, Vu Hoang; Tam, Le Dong.
World food prices have experienced dramatic increases in recent years. These “shocks” affect food importers and exporters alike. Vietnam is a major exporter of rice, and rice is also a key item in domestic production, employment and consumption. Accordingly, rice price shocks from the world market have general equilibrium impacts and as such, their implications for household welfare are not known ex ante. In this paper we first present a simple framework for understanding the direct and indirect welfare effects of a global market shock of this kind. Second, we quantify the transmission of the price shock from global indicator prices to domestic markets. Third, we then we use an applied general equilibrium (AGE) model to simulate the effects of domestic...

INCREASES IN DEMAND FOR FOOD IN CHINA AND IMPLICATIONS FOR WORLD AGRICULTURAL TRADE AgEcon
Koo, Won W.; Lou, Jianqiang; Johnson, Roger G..
China is experiencing rapid economic growth, resulting in increased demand for food. Estimates are made of Chinese production and consumption of rice, wheat, corn, and soybeans to the year 2005. Results indicate that China will become a large net importer especially of wheat, corn, and soybeans. China's grain shipping and handling industries will need to be expanded to handle the increased imports. Note: Figures are not included in the machine readable copy--contact the authors for more information.

Agro-well and pump diffusion in the dry zone of Sri Lanka: Past trends, present status and future prospects AgEcon
Kikuchi, Masao; Weligamage, Parakrama; Barker, Randolph; Samad, Madar; Kono, Hiroichi; Somaratne, H.M..
The use of shallow wells, equipped with small pumps, to lift groundwater has spread rapidly in many agricultural regions of tropical monsoonal Asia. In Sri Lanka, the rapid and pervasive invasion of agro-wells and pumps drew the attention of policymakers and researchers, but many questions were left unanswered due to lack of research in the area. This study aims to fill this gap in knowledge, based on observations and data obtained in field surveys conducted in major and minor irrigation schemes in the dry zone of Sri Lanka. This report gives the key findings of this study into the pattern, extent and causes of the spread and use of agro-wells and pumps in traditional villages and irrigated settlement schemes. It investigates farmer investments in...
