An Assessment of the Economic, Environmental and Social Impacts of the Ricecheck Program AgEcon
Singh, Rajinder Pal; Brennan, John P.; Lacy, John; Steel, Felicity.
Ricecheck, a best management practices extension program for rice production in Australia, was developed by the NSW Department of Primary Industries advisory staff, Finley, in 1986. The program is based on eight best management practice recommendations called ‘Key Checks’ that are considered essential for achieving high yields. Economic analysis of the program reveals that there are significant financial, social and environment benefits from the adoption of the program. The results further reveal that the funds invested since 1986 by both NSW Department of Primary Industries and the Rural Industries Research and Development Corporation have been sound investments.

Farming Systems in the Pastoral Zone of NSW: An Economic Analysis AgEcon
Khairo, Salahadin A.; Mullen, John D.; Hacker, Ronald B.; Patton, Dean A..
A ‘broad brush’ picture of farming in the pastoral zone of NSW is presented in this report. The pastoral zone of NSW is characterised by wide variations in climatic conditions, soil type and vegetation species. Hence representative faming system analysis was conducted for three sub-regions - the Upper Darling, the Murray-Darling and Far West. The regions were defined and described in terms of their resources, climate and the nature of agriculture. The main enterprises that farmers choose between were described and whole farm budgets and statements of assets and liabilities for the representative farms were developed. The representative farm models were used to compare traditional Merino based sheep enterprises with alternative sheep enterprises where meat...

Sheep CRC Renewal Proposal: Economic Evaluation of the Proposed Scientific Themes AgEcon
Griffith, Garry R.; Vere, David T.; Jones, Randall E..
The Australian sheep industry and its associated research and development agencies have developed a proposal for the CRC for Sheep Industry Innovation. “Top-down” and “bottomup” procedures were used to assess the expected economic benefits from this proposal. Formal “with-CRC” and “without-CRC” scenarios were defined for each product and each research theme. Relevant costs were similarly defined. The requested investment by the Commonwealth and the Australian sheep industry in the CRC is assessed relative to a scenario where an alternative, lower cost research program into this industry is implemented. These extra resources have a discounted value of about $34 million over the 25-year period of this evaluation. These resources are sufficient to allow some...

LIVESTOCK PRODUCTIVITY IN CHINA: DATA REVISION AND TOTAL FACTOR PRODUCTIVITY DECOMPOSITION AgEcon
Ma, Hengyun; Rae, Allan N.; Huang, Jikun.
Studies of total factor productivity in livestock production are rare, but when available provide useful information especially in the context of developing countries such as China where livestock is becoming more important in the domestic agricultural economy. We estimate total factor productivity (TFP) for four major livestock products in China and by employing the random coefficient frontier approach, decompose productivity growth into its technical efficiency and technical progress components. Efforts were made to adjust and augment the available livestock statistics. The results show that growth in TFP and its components varied between the 1980s and the 1990s as well as over production structures. While there is evidence of considerable technical...

The Impact of Agricultural Technology Adoption on Poverty: The case of NERICA rice varieties in Benin AgEcon
Adekambi, Souleimane Adeyemi; Diagne, Aliou; Simtowe, Franklin; Biaou, Gauthier.
This study examines the relationship between agricultural technology adoption and poverty with a focus on New Rice varieties for Africa (NERICA). The NERICAs are a group of rice varieties developed by the Africa Rice Centre during the 1990s, resulting from the inter-specific crosses between the Oryza sativa high yielding rice species from Asia and the locally adapted and multiple-stress resistant Oryza glaberrima African rice species. They are believed to provide great hope for African agriculture. Introduced in Benin in 1998, there has been no published analysis on the impact of their adoption by farmers. The paper uses the counterfactual outcomes framework of modern evaluation theory to estimate the Local Average Treatment Effect (LATE) of NERICA...

Trends in Pulse and Oilseed Crops in Winter Cereal Rotations in NSW AgEcon
Brennan, John P.; Sykes, John D.; Scott, J. Fiona.
The key aims in this study are to assess the current level of importance of pulse and oilseed (broadleaf) crops in winter cereal rotations in NSW, and to identify recent trends. The production of broadleaf crops has increased in each region of NSW, but different crops have been favoured. Canola has played a key role in southern regions, and chickpea in the northern regions. In many areas, pulse crops have been grown more because of rotational benefits than their direct gross margins. If recent trends continue, the role of broadleaf crops will increase to 25% of the area sown to field crops in NSW by 2020. However, that will only be achieved with a focussed effort in both research and extension activities.

Induced Innovations and Foreign Workers in U.S. Agriculture AgEcon
Napasintuwong, Orachos; Emerson, Robert D..
A cost function approach of induced innovation is used to measure the biases in U.S. agricultural technology between 1948-1994. The results show significant labor-saving, capital-using technical change. Focusing on the impact of migration policy on labor-saving technology, a simulaton of different rates of labor-saving technical change is conducted. The simulation shows decreases in elasticity of labor demand and demand quantity, and an increase in wage rate as technology becomes more labor-saving.

Analysis of the Impact of CIMMYT Research on the Australian Wheat Industry AgEcon
Brennan, John P.; Quade, Kathryn J..
Wheat genetic materials developed from research at the International Maize and Wheat Improvement Center (CIMMYT) in Mexico for developing countries have provided spillover benefits to Australia. Varieties developed from those genetic materials have resulted in yield increases in Australia. CIMMYT’s success in developing countries has also reduced the world price for wheat. While the lower prices affect returns in Australia, the increased yields in Australia from the CIMMYT spillovers have provided benefits to Australia averaging A$30 million per year since 1973. If these benefits are to continue in the future, Australia must continue its close relationship with CIMMYT.

The Economic, Environmental and Social Benefits to NSW from Investment in the CRC for Beef Genetics Technologies AgEcon
Griffith, Garry R.; Parnell, Peter F.; McKiernan, William A..
The Australian cattle and beef industry and the associated RD&E community recently developed a successful proposal for the CRC for Beef Genetic Technologies. The expected benefits from the proposed scientific programs of the renewed CRC were estimated using the DREAM economic modelling framework. A “top-down” assessment philosophy was used that included explicit “with-CRC” and “without-CRC” scenarios. The benefit from the extra investment and consequent research effort due to funding the CRC is estimated to be worth over $1.4b in present value terms. Every $1 of these extra resources brought into the Australian beef industry through funding the new Beef CRC is expected to return around $35 to the industry. The marginal returns to the NSW beef industry...

An Evaluation of the Economic, Environmental and Social Impacts of NSW DPI Investments in IPM Research in Lettuce AgEcon
Orr, Leanne M.; McDougall, Sandra; Mullen, John D..
Research into IPM technologies has been conducted by NSW DPI for over 20 years. Evaluating the returns from investment in specific research and development projects is an important component of the NSW DPI science and research program. An economic evaluation has been conducted of IPM in managing invertebrate pests in lettuce in NSW. We found that there has been widespread adoption of IPM practices amongst NSW lettuce growers leading to a flow of economic benefits to the lettuce industry and the community. Important environmental and human health benefits were also identified. A benefit-cost ratio of 2 was calculated for the return to NSW DPI investment in lettuce IPM research which while satisfactory, is lower than returns calculated for other agricultural...

Australian Sheep Industry CRC: Economic Evaluations of Scientific Research Programs AgEcon
Vere, David T.; Griffith, Garry R.; Silvester, Luke T..
By the end of its seven-year term in 2007-08, the Australian Sheep Industry CRC (Sheep CRC) will have received total funds of about $90 million, that comprises Commonwealth and industry funding of $30 million, and in-kind contributions valued at $60 million. This level of public and private funding emphasises the need for the Sheep CRC to demonstrate that its research programs will generate sound economic returns to all stakeholders. This paper reports an evaluation of the potential economic value of the achievements of the Sheep CRC at the midpoint of its term of operations at which it has some completed research and a large volume of research in progress. The main question that has been addressed in this evaluation concerns the nature and likely...

An Equilibrium Displacement Model of the Australian Sheep and Wool Industries AgEcon
Mounter, Stuart W.; Griffith, Garry R.; Piggott, Roley R.; Fleming, Euan M.; Zhao, Xueyan.
This report documents the specification of an equilibrium displacement model (EDM) of the Australian sheep and wool industries. The model is capable of estimating and comparing the potential benefits from R&D and generic promotion investments, and other policy changes, in the different sectors and markets of the Australian sheep and wool industries. Inclusive in the model are the multiple components of the Australian sheep and wool industries to account for cross-product interactions not considered in most previous studies. A high degree of industry disaggregation within the model enables estimation of the distribution of the potential benefits among the various industry sectors and across different regional environments. A number of hypothetical...

An Economic Evaluation of a Pest Management Control Program: "Outfox the Fox" AgEcon
Jones, Randall E.; Saunders, Glen; Balogh, Suzy.
Foxes are regarded as a serious pest of environmental and grazing systems in Australia. The fox is a recognised predator of native wildlife and has been a significant contributor to the population decline of many native mammal, bird and reptile species. There are also claims that foxes may account for up to 30% of lamb mortalities in some areas, while mortality due to predation of 2 to 5% is more likely in most regions. The ‘Outfox the Fox’ program was established by NSW Agriculture in conjunction with a number of Rural Land Protection Boards to achieve a more strategic and coordinated fox baiting program. This program relies on a community driven and integrated management approach to the problem. The main features are to synchronise baiting across...

Labor Substitutability in Labor Intensive Agriculture and Technological Change in the Presence of Foreign Labor AgEcon
Napasintuwong, Orachos; Emerson, Robert D..
The Morishima elasticity of substitution (MES) is estimated to address factor substitutability in Florida agriculture during 1960-1999. By adopting a profit maximization model of induced innovation theory, the MES's between hired and self-employed labor and the MES's between labor and capital provide implications for future immigration policies.
