Download or read book Strategies for Evaluating the Data Quality of the Canadian Census of Agriculture written by Stuart D. Pursey and published by . This book was released on 1993 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper discusses approaches to evaluating the data quality of the Canadian Census of Agriculture (CEAG). Section 1 describes the role that the 1991 data quality evaluation has played in encouraging development of future data quality evaluations. Section 2 discusses approaches to future data quality evaluations: considering the meaning of data quality, the purposes of data quality evaluations, and the framework of a data quality evaluation. A model of an information system provides a useful framework for a data quality evaluation. Section 3 describes one such model that has been developed in the context of an agriculture information system.

Download or read book Precision agriculture 07 written by J.V. Stafford and published by BRILL. This book was released on 2023-08-28 with total page 876 pages. Available in PDF, EPUB and Kindle. Book excerpt: "With ever-increasing pressures on world agriculture in both economic and environmental terms, application of the concept of precision agriculture is one way of enabling farmers and producers to cope. ‘Doing arable agriculture and horticulture more precisely’ means that the use of inputs is optimised, crop yield and quality are maximised and leakage of agro-chemicals and fertilisers to the environment is minimised. This publication contains papers presented at the 6th European Conference on Precision Agriculture. The papers reflect the wide range of disciplines encompassed by precision agriculture, including: soil physics, crop physiology, agronomy, IT, agricultural technology, sensor technology, remote sensing, geostatistics and environmental science. The wide range of research topics reported will be a valuable resource for researchers, advisors, teachers and professionals in agriculture long after the conference has finished. Peer-reviewed papers from the 3rd European Conference on Precision Livestock Farming are presented in a companion proceedings, Precision livestock farming ’07."

Download or read book WaPOR V2 quality assessment written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-12-04 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document presents the results of a validation of the version-2 of the WaPOR database, produced by the FRAME consortium partners, eLEAF and VITO. The report summarises the work done by the validation partner (ITC-UTwente) to assess the quality of the new V2 core data components, currently used to estimate and derive agricultural water productivity for Africa and the Near East. WaPOR represents a comprehensive open access data portal that provides information on biomass productivity (with focus on food and agriculture production) and evapotranspiration (evaporative losses and water use) for Africa and the Near East in near real time covering the period from 1 January 2009 to date. WaPOR offers continuous data on a 10-day average basis across Africa and the Near East at three spatial resolutions. The continental level-1 data (250m) cover entire Africa and the Near East (L1). The national level-2 (100m) data cover 21 countries and four river basins (L2). The third level-3 data (30m) cover eight irrigation areas (L3). The quality assessment focused on the core data of the WaPOR database i.e., the evaporative loss components: plant transpiration (T), soil evaporation (E) and interception (I) combined in ETI, the net primary productivity – NPP, the total (TBP) and above ground biomass productivity (AGBP) and reference evapotranspiration – RET.
Download or read book World Programme for the Census of Agriculture 2020 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-02-04 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: FAO has supported member countries to carry out their national agricultural censuses since 1945, through the development and dissemination of international standards, concepts, definitions and methodologies as well as technical assistance. In 2015, FAO published Volume 1 of the World Programme for the Census of Agriculture 2020 (WCA 2020) “Programme, concepts and definitions”, the tenth decennial programme that provides guidelines for implementation of national agricultural censuses in the 2016-2025 decade. Volume 1 deals with the methodological and conceptual aspects of the census of agriculture. In addition to the use of international standards, the proper conduct of an agricultural census also depends on adequate planning, implementation, use of resources and quality assurance throughout all stages of the census. In light of this, Volume 2 of WCA 2020 “Operational guidelines” has been designed to guide national census practitioners responsible for conducting the agricultural census. It deals with the practical steps involved in actually conducting an agricultural census in the field. Volume 2 is a revised and updated edition of “Conducting Agricultural Censuses and Surveys”, published by FAO in 1996. The revision is opportune not only in view of the recent publication of the new census programme and methodology but also in view of the substantial changes witnessed in the census technological environment over the last two decades. The availability of digital, mobile and more affordable tools for data capture, geo-positioning, remote sensing imaging, digital archiving and online dissemination have provided new cost-effective alternatives to traditional ways of conducting the agricultural census.

This book was released on 2020-01-22 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why model? Agricultural system models enhance and extend field research...to synthesize and examine experiment data and advance our knowledge faster, to extend current research in time to predict best management systems, and to prepare for climate-change effects on agriculture. The relevance of such models depends on their implementation. Methods of Introducing System Models into Agricultural Research is the ultimate handbook for field scientists and other model users in the proper methods of model use. Readers will learn parameter estimation, calibration, validation, and extension of experimental results to other weather conditions, soils, and climates. The proper methods are the key to realizing the great potential benefits of modeling an agricultural system. Experts cover the major models, with the synthesis of knowledge that is the hallmark of the Advances in Agricultural Systems Modeling series.
Download or read book CAADP BR data improvements and challenges A critical analysis of theme 2 in the 3rd BR cycle written by Benin, Samuel and published by Intl Food Policy Res Inst. This book was released on 2022-11-22 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: To improve the quality of data and reporting for the fourth cycle of the Comprehensive Africa Agriculture Development Programme (CAADP) Biennial Review (BR),1 the African Union (AU) conducted a critical analysis of the process, data, and reporting associated with the third BR. Improving the quality of the BR data will increase the reliability of policy implications derived from rigorous analysis of the data, which may in turn encourage policymakers to implement the resulting recommendations to accelerate agricultural transformation and achieve the goals and targets of the Malabo Declaration. This note summarizes the critical analysis conducted by the technical working group for Theme 2 (TWG2) on enhancing investment finance in agriculture.2 The analysis is based on review of the BR technical documents, evaluation of the processes for data collection and management, and a check of data consistency, including analysis of outliers, illogical or implausible values, and discrepancies with other publicly available datasets. Preliminary findings of the analysis were discussed at several meetings with stakeholders interested in the theme. The results and recommendations were presented at a general meeting organized by the AU with all the TWGs and stakeholders on August 1–5, 2022, in Yaoundé, Cameroon. This note will be useful for the AU and its technical partners for developing standards and guidelines for conducting uniform critical analyses across the various BR technical working groups.
