We present a new method for ecologically sustainable land use planning within multiple land use schemes. Our aims were (1) to develop a method that can be used to locate important areas based on their ecological values; (2) to evaluate the quality, quantity, availability, and usability of existing ecological data sets; and (3) to demonstrate the use of the method in Eastern Finland, where there are requirements for the simultaneous development of nature conservation, tourism, and recreation. We compiled all available ecological data sets from the study area, complemented the missing data using habitat suitability modeling, calculated the total ecological score (TES) for each 1 ha grid cell in the study area, and finally, demonstrated the use of TES in...

An Econometric Analysis of the Environmental Benefits Provided by the Conservation Reserve Program AgEcon
Fleming, Ronald A..
Over $1.7 billion has been spent on the Conservation Reserve Program (CRP) since 1985. The purpose of this study is to show that these expenditures have aided the environment. Rather than quantify changes in environmental variables, a spatial econometric model is used to test if CRP enrollments are greater in counties with poorer environmental quality. In seven of nine regions, CRP enrollments are higher in counties with an environmental concern. This positive finding justifies past expenditures by the CRP and supports continued funding as an environmental program. The CRP is targeting current environmental concerns that will lead to future improvement.

Armazenamento e recuperação de dados georreferenciados de condutividade elétrica do solo na Rede de Agricultura de Precisão da Embrapa. Infoteca-e
SPERANZA, E. A.; QUEIROS, L. R.; RABELLO, L. M.; GREGO, C. R.; BRANDÃO, Z. N..
Resumo: Este trabalho descreve a implantação de uma ferramenta para armazenamento em uma base de dados espacial de informações georreferenciadas de condutividade elétrica do solo obtidas em campo. A partir dos dados coletados, mapas são gerados para suporte à tomada de decisão em agricultura de precisão. Este trabalho utilizou coletas de dados realizadas em uma área de plantio de cana-de-açúcar em Mogi Mirim, SP no âmbito do projeto da Rede de Agricultura de Precisão da Embrapa (Rede AP).
Tipo: Capítulo em livro técnico (INFOTECA-E) Palavras-chave: Dados georreferenciados; Condutividade elétrica do solo; Base de dados geoespacial; Georreferenciamento; Agricultura de Precisão; Spatial data; Georeferencing; Precision agriculture.

Estimating fishing effort in small-scale fisheries using GPS tracking data and random forests ArchiMer
Behivoke, Faustinato; Etienne, Marie-pierre; Guitton, Jérôme; Randriatsara, Roddy Michel; Ranaivoson, Eulalie; Léopold, Marc.
During the last decade spatial patterns of industrial fisheries have been increasingly characterized using tracking technologies and machine learning analytical algorithms. In contrast, for small-scale fisheries, fishers’ behaviour for estimating and mapping fishing effort has only been anecdotally explored. Following a comparative approach, we conducted a boat tracking survey in a small-scale reef fishery in Madagascar and investigated the performance of a learning random forest algorithm and a speed threshold for estimating and mapping fishing effort. We monitored the movements of a sample of 31 traditional sailing fishing boats at around 45 s time interval using small GPS trackers. A total of 306 daily tracks were recorded among five gear types (beach...

Geo em cápsulas: aplicações de geoserviços e composição de mapas com QGIS. Infoteca-e
COUTINHO, E. A. T.; WEBBER, D. C.; GODOY, D.; DART, R. de O.; VASQUES, G. de M.; CRUZ, P. V..
Neste tutorial serão descritos três diferentes geoserviços disponíveis na plataforma GeoNode, a saber, WMS (Web Map Service), WFS (Web Feature Service) e WCS (Web Coverage Service), e como utilizá-los para consumir dados disponíveis no GeoInfo utilizando o software livre QGIS (utilizou-se a versão 3.18, porém é possível utilizar qualquer versão). Adicionalmente, é apresentado um passo a passo para elaborar layout de mapas com as camadas do GeoInfo consumidas pelos geoserviços.
Tipo: Documentos (INFOTECA-E) Palavras-chave: Geoprocessamento; Dados espaciais; Sistema de Informação Geográfica; Base de Dados; Análise de Dados; Databases; Geographic information systems; Computer software; Spatial data.

NASYP: Online expert tool on the control of major-accident hazards involving dangerous substances AgEcon
Kahuda, Daniel; Vach, Marek; Cerba, Otakar; Krivanek, Zbynek; Jezek, Jan; Charvat, Karel; Vohnout, Premysl; Dvorak, V..
NASYP is an online Geoportal tool being developed in cooperation with state and regional authorities to improve insufficient practices based on implementation of Directive nr. 2003/105/ES on the control of major-accident hazards involving dangerous substances. The tool is applicable for managing the permits, reporting and regular monitoring issues. Furthermore, it’s applicable for a risk assessment and a rapid management of disasters in the initial phase. There’re simple modeling tools included to simulate early stages of the contamination caused by disasters occurred to be used for decision making and effective use of emergency services. In this manner, there’re low atmospheric and surface water pollutions taken into account. For the study area, Liberec...

Network approaches for understanding rainwater management from a social-ecological systems perspective Ecology and Society
Prager, Steven D.; International Center for Tropical Agriculture (CIAT); s.prager@cgiar.org; Pfeifer, Catherine; International Livestock Research Institute (ILRI); c.pfeifer@cgiar.org.
The premise of this research is to better understand how approaches to implementing rainwater management practices can be informed by understanding how the people living and working in agroecosystems are connected to one another. Because these connections are via both social interactions and functional characteristics of the landscape, a social-ecological network emerges. Using social-ecological network theory, we ask how understanding the structure of interactions can lead to improved rainwater management interventions. Using a case study situated within a small sub-basin in the Fogera area of the Blue Nile Basin of Ethiopia, we build networks of smallholders based both on the biophysical and social-institutional landscapes present in the study site, with...

Spatial Considerations in Air- and Water-Quality Tradeoffs for Animal Agriculture AgEcon
Gollehon, Noel R.; Aillery, Marcel P..
Total and average per ton costs of land-applying manure demonstrate the importance of spatial factors on the potential effect of policy limits for water and air emissions. Per ton costs vary with the need to transport greater distances for land application, reflecting the spatial distribution of cropland and animal production. Costs are estimated with a regional modeling framework, applied to the Chesapeake Bay watershed that integrates GIS-based spatial data within an optimization framework.
Tipo: Conference Paper or Presentation Palavras-chave: Regional optimization; Geographic information systems; Spatial data; Manure management; Confined animals; Nutrient policies; Water quality; Air quality; Chesapeake Bay; Environmental Economics and Policy; Livestock Production/Industries.
