Agroenvironmental modeling and the digital transformation of agriculture. Introduction. The evolution of agroenvironmental modelling. Agroenvironmental modeling products to support decision-making. Databases for agricultural and environmental research: Agritempo, Conprees.... ... Repository: BDPA Publication year: 2023
Modelling conditional measures of efficiency to assess the influence of covariates on agricultural production in Brazil. ABSTRACT: Brazilian agriculture is productive, efficient, and profitable for a few farmers. However, due to the restricted access to technology, the major part of the rural producers are marginalized... ... Repository: BDPA Publication year: 2022
Computing confidence intervals for output oriented DEA models: an application to agricultural research in Brazil. We define and model the research production at Embrapa, the major Brazilian institution responsable for applied agricultural research. The main theoretical framework is Data Envelopment Analysis - DEA... ... Repository: BDPA Publication year: 2009
Probabilistic measures of efficiency and the influence of contextual variables in nonparametric production models: an application to agricultural research in Brazil. In a research institution it is important to identify which management practices have influence on production efficiency. In this paper we assess the statistical significance of contextual variables t... ... Repository: BDPA Publication year: 2010
Modeling of pesticide emissions for life cycle assessment of agricultural products. Abstract: Brazil is the fourth largest food producer in the world. The agricultural sector contributes significantly to the Bralizian economy, representing 23% of GDP in 2016. Government and private i... ... Repository: BDPA Publication year: 2018
Computational modeling for irrigated agriculture planning. Part II: risk analysis. Techniques of evaluation of risks coming from inherent uncertainties to the agricultural activity should accompany planning studies. The risk analysis should be carried out by risk simulation using te... ... Repository: BDPA Publication year: 2008
Hydrological modeling of the Ribeirão das Posses: an assessment based on the Agricultural Ecosystem Services (AgES) watershed model. Abstract: Southeastern Brazil has recently experienced drought conditions that have impacted watershed conservation and the management of water quality and quantity for agricultural and urban demands.... ... Repository: BDPA Publication year: 2017
The Agricultural Ecosystems Services (AgES) watershed model is used to estimate the spatial complexity of soil hydraulic properties in a field-scale agricultural watershed, Colorado, USA. Soil hydraulic properties that control water storage flow rates can vary markedly in space, and surface layers may vary temporally due to management events, reconsolidation and biological activity. Fi... ... Repository: BDPA Publication year: 2018
Assessing agriculture-water links at the basin scale: hydrologic and economic models of the São Francisco River Basin, Brazil. This article uses a basin-wide hydrologic model to assess the hydrologic and economic effects of expanding agriculture in the São Francisco River Basin, Brazil. Repository: BDPA Publication year: 2009
A spatially distributed hydroeconomic model to assess the effects of drought on land use, farm profits, and agricultural employment. In this paper a high-resolution linked hydroeconomic model is demonstrated for drought conditions in a Brazilian river basin. The economic model of agriculture includes 13 decision variables that can... ... Repository: BDPA Publication year: 2009
