The purpose of the plowprint is to track annual grassland conversion to cropland across the Mississippi River Basin and Great Plains region, and to provide a way to measure the loss of this important habitat type, against which annual changes can be compared. This report tracks changes at the sub-regional scale, as well as in the context of the broader geography, and highlights key elements of change each year. The focus of this report is on changes in grassland conversion from 2014-2015, based on data from the USDA National Agricultural Statistics Service Cropland Data Layer and the Agriculture and Agri-Food Canada Annual Crop Inventory. For this analysis, cropland is defined as any annually planted agricultural...

El estado de Chihuahua es el más extenso de la República Mexicana, representa el 12.6% del territorio del país (INEGI, 2001) y posee una amplia gama de recursos naturales de los que se desprenden diversas actividades económicas (INEGI, 2003), por lo anterior resulta indispensable la disponibilidad de información eficiente de los recursos naturales que permita el manejo adecuado de los mismos. La ley forestal de nuestro país, señala que la evaluación de los recursos naturales debe integrar “información estadística y cartográfica”, que permita conocer la dinámica del cambio de vegetación forestal, para poder evaluar las tasas de deforestación y sus principales causas (CONAFOR, 2010). Actualmente la cartografía...

ANTECEDENTES La Ley de Aguas Nacionales, que entró en vigor el 2 de diciembre de 1992, refuerza el marco institucional para la administración del recurso y consolida a la Comisión Nacional del Agua (CONAGUA) como autoridad federal única en materia de cantidad y calidad del recurso hidráulico nacional, superficial y subterráneo. Dentro de este Marco Institucional es que en 1992 se propone el desarrollo de un Sistema de Información Geográfica del Agua (SIGA) que se constituyera en una herramienta que permitiera integrar, consultar, analizar y desplegar la información georreferenciada para que las unidades de la CONAGUA realizaran con mayor eficiencia las labores de planeación y administración del agua. OBJETIVOS...

Metadata: synthmap08.zip, 69,967kB, 11 March 2008. Feature type: ArcGRID. Completeness of data: 100% of Nevada plus edges of adjacent states. Currency of data: various, up to winter 2007/08; updates are expected in the future. Scale at which data are believed to meet National Map Accuracy Standards: 1:100,000 in most areas. Key attributes: International Vegetation Classification (IVC) types at ecological system, alliance, and association levels, with additional fields indicating the IVC level, IVC code, and origin of the data. See the accompanying documentation on our Library page. An ArcGIS layer file is included for convenient display symbology. The data table is included as an Excel file as well.

The National Land Cover Database (NLCD) serves as the definitive Landsat-based, 30-meter resolution, land cover database for the Nation. NLCD provides spatial reference and descriptive data for characteristics of the land surface such as thematic class (for example, urban, agriculture, and forest), percent impervious surface, and percent tree canopy cover. NLCD supports a wide variety of Federal, State, local, and nongovernmental applications that seek to assess ecosystem status and health, understand the spatial patterns of biodiversity, predict effects of climate change, and develop land management policy. NLCD products are created by the Multi-Resolution Land Characteristics (MRLC) Consortium, a partnership of...

How well are we protecting common plants and animals? Gap Analysis is the science of answering this question. Developing the data and tools to support that science is the mission of the USGS Gap Analysis Program (GAP). GAP works to ensure that common species – those that are not officially endangered – remain common by identifying those species and plant communities that are not adequately represented in existing conservation lands. Learn more about Gap Analysis >> We work with a wide range of government, academic, non-profit and private partners, providing them with essential data and analyses that they can use to protect the habitats on which the survival of common species depends.

Currently in Mexican arid regions, high pressure is applied to natural resources for their utilization, principally in the form of: uncontrolled grazing omnipresent in every corner accessible to cattle, opening high risk lands up for crop production, overexploitation of aquifers, discharge of contaminated waters, riparian areas drying up, exploration and uncontrolled exploitation of natural goods: flora, fauna, oil, gas, etc., without promotion of participatory activities for resource conservation and improvement among users, which results in a poor understanding of the precarious condition of the grassland environment. Se ejerce actualmente en México, una elevada presión de uso de los recursos naturales de estas...

These map products of the North American Land Change Monitoring System (NALCMS) are a collaborative initiative between Canada, Mexico, and the United States to monitor land cover - the observed physical cover on the surface of the Earth - and its change over time. These maps represents land cover in 2005, 2010, and land cover change from 2005-2010 based on Moderate Resolution Imaging Spectroradiometer (MODIS) satellite imagery monthly composites at 250 m spatial resolution. Nineteen land cover classes were defined using the Land Cover Classification System (LCCS) standard developed by the Food and Agriculture Organization (FAO) of United Nations. The NALCMS was developed to depict information about land cover and...
