Última Agricultural Technology Adoption and Land Productivity: Evidence from the Rice-Prawn Gher Farming System in Bangladesh AgEcon Barmon, Basanta Kumar; Kondo, Takumi; Osanami, Fumio. Rice-prawn gher (RPG) farming system is an indigenous agricultural technology solely developed by farmers since mid 1980s. The present study aims to estimate the land productivity of modern varieties (MV) paddy production under RPG and (year-round modern varieties) YRMV paddy farming systems in the southwest Bangladesh. The RPG farming system has significant impacts on inputs used in MV boro paddy production. The findings of the study indicate that more chemical fertilizers were used in per ha MV boro paddy production under YRMV paddy farming in comparison with RPG farming. Similarly, per ha cost of irrigation, pesticides and land preparation were also higher in MV boro paddy production under YRMV paddy farming system compared to RPG farming system. The...

Ano: 2018 URL: http://www.infoteca.cnptia.embrapa.br/infoteca/handle/doc/1101880 El índice CONEAT como medida de productividad y valor de la tierra. AgEcon Lanfranco, Bruno A.; Sapriza, Gonzalo. El objetivo de la presente investigación es cuantificar el impacto del índice de productividad CONEAT sobre los precios pagados por los inmuebles rurales en el Uruguay. El índice CONEAT intenta expresar la relación entre la capacidad de producción de un predio, medida en términos de carne y lana, y las unidades de suelo que lo componen. La ventaja de su uso radica en su fácil comprensión por parte de los agentes. La principal crítica es que utiliza exclusivamente parámetros de producción ganadera que hacen cuestionable su uso cuando se comparan inmuebles con otras aptitudes productivas. Sin embargo, aun se lo utiliza frecuentemente para tasar inmuebles rurales o comparar productividad entre inmuebles. Para estimar el valor monetario implícito que los...

González U,Jorge ; Velasco H,Roberto . Climatic change will affect crop yields and management. By the year 2050, the mean temperature could increase by 1.5 ºC; and by the year 2100 between 1.0 to 3.5 ºC. There are few studies on this subject in Chile. At the international level, estimated climatic changes in temperate and tropical zones could negatively affect wheat (Triticum vulgare L.) and corn (Zea mays L.) production, as examples. The objective of this study was to determine the relationship between agricultural systems and climatic change by using the Ricardian Method. Specific objectives were to evaluate and quantify the relationship of climatic variables (precipitation and temperature) with economic variables under several realities of farms, to simulate the impact of scenarios of...

AgEcon Almeida, Eduardo Simões de; Perobelli, Fernando Salgueiro; Ferreira, Pedro Guilherme Costa. This work analyzes the convergence of land productivity for Brazilian regions from 1991 to 2003. It evaluates if there is or not convergence of the agricultural productivity, controlling explicitly for spatial effects. To do so, an exploratory spatial data analysis was previously implemented and the presence of spatial autocorrelation for the land productivity was detected. In addition, spatial econometric models were developed for the convergence analysis.

This working paper is the outcome of a data collection process initiated under the advice of Dr. Shigeo Yashima of the International Irrigation Management Institute (IIMI). The objective of this data collection process was to make a preliminary assessment of irrigation performance in Sri Lanka using irrigation systems with different backgrounds to identify areas for further research.

Ano: 2011 URL: http://purl.umn.edu/117482 Land-saving technologies 2021. Infoteca-e TELHADO, S. F. P. e; CAPDEVILLE, G. de. The adoption of a considerable number of technologies on various fronts of the production process has allowed the production of high volumes, with high quality, in a sustainable manner in all aspects, in addition, it has allowed the protection of Brazilian forests both in agricultural properties as well as in native areas. The technological capacity to carry out territorial management, integrated pest and disease management, the use of integrated production systems that extend the life of soils, among other aspects, are the factors that guarantee the success of Brazilian agriculture. Therefore, with the information contained in this document, it is evident that, due to the adoption of technologies developed by Embrapa and partners, agriculture is...

This study analyzes how market imperfections affect land productivity in a degraded low-potential cereal- livestock economy in the Ethiopian highlands. A wide array of variables is used to control for land quality in the analysis. Results of three different selection models were compared with least squares models using the HC3 heteroskedasticity-consistent covariance matrix estimator. Market imperfections in labor and land markets were found to affect land productivity. Land productivity was positively correlated with household male and female labor force per unit of land. Female-headed households achieved much lower land productivity than male- headed households. Old age of household heads was also correlated with lower land productivity. Imperfections in...

Ano: 2001 URL: http://purl.umn.edu/16066 The paradox of household resource endowment and land productivity in Uganda AgEcon Ainembabazi, John Herbert; Angelsen, Arild. The paper investigates the conflicting findings in empirical studies linking land productivity to plot size, livestock ownership, investment in farm assets, and land improvement practices. The conflicting impacts found are partly as a result of different model specifications, the type of data used – panel or cross sectional data – and possibly due to imperfections in rural markets. We control for these problems using household and plot level panel data from rural farmers in Uganda. We find that ownership of cattle has a negative and significant impact on land productivity. Investment in farm related assets, land improvements and other small livestock, however, significantly increases productivity. The conflicting impacts are a result of measurement error....
