• Wheat farmers see infrared

Infrared sensors help better target fertilizer for wheat on large commercial farms in northern Mexico, cutting production costs and reducing nitrogen run-off into coastal areas. CIMMYT July 2007 newsletter.

• Farmers discuss nitrogen sensor technology

This spring the Asociacion de Organismos Agricolas del Sur de Sonora (AOASS), the umbrella institution for farmers unions, organized a meeting to discuss the results of this season's trials of nitrogen sensor technology. CIMMYT June 2006 report.

• Of Wheat and Weather
  

October 2005 CIMMYT newsletter reports on a new study from the Carnegie Institute of Washington, Stanford University, and CIMMYT that shows wheat yield gains in northern Mexico could be due mostly to the weather. The study was published in Field Crops Research.

• Wheat and Water win
  

CIMMYT, under the direction of Yaqui Principal Investigator IvanOrtiz-Monasterio, shows technology to enhance farmer income and reduce ocean pollution in May 2005 CIMMYT report.

• Ocean ecosystems plagued by agricultural runoff
  

March 10, 2005 article in the Stanford Report reports that Yaqui Valley researchers from CESP used satellite imagery to demonstrate how agricultural runoff fuels algal blooms in vulnerable areas of the ocean.

• Field Laboratory Identifies Ways to Reduce Environmental Impacts of Intensive Agriculture

CIMMYT report released May 2004 from Yaqui Principal Investigator, Ivan Ortiz-Monasterio looks at how remote sensing is being used to make thousands of observations across the Valley to determine how different sowing dates affect wheat yields. Remote sensing is also being used for tracking nitrogen derivatives that are released into the atmosphere or leached into the soil with irrigation water.

• Drought enters ninth year in birthplace of the Green Revolution

Article appearing in Spring 2004 edition of Encina Columns unveils the crisis facing farmers in the Yaqui Valley.

• 2004 Nitrogen management study by Yaqui researchers Lobell, Ortiz-Monasterio, and Asner released in Field Crops Research

Increased efficiency of nitrogen (N) fertilizer use may be achieved with management practices that account for spatial variability in soil properties and temporal variability in climate, says authors of journal article.

• Yaqui researchers David Lobell and Gregory Asner publish in June 2003 issue of IEEE Transactions on Geoscience and Remote Sensing

The paper entitled, 'Comparison of Earth Observing-1 ALI and Landsat ETM+ for Crop Identification and Yield Prediction in Mexico' presents a comparison of Earth Observing 1 (EO-1) Advanced Land Imager (ALI) and Landsat-7 Enhanced Thematic Mapper Plus (ETM+) images collected over the Yaqui Valley, Sonora, Mexico.

• Proceedings of the National Academy of Sciences (PNAS) publishes two papers by Yaqui Valley Principal Investigator Pamela Matson

Dr. Pamela Matson contributes to the publication of two articles, 'A framework for vulnerability analysis in sustainability science' and 'Illustrating the coupled human-environment system for vulnerability analysis: Three case studies' in the July 8, 2003 issue of PNAS.

• Yaqui Researchers Publish in Science

Stanford Yaqui researchers, David Lobell and Gregory Asner, recently published the paper 'Climate and Management Contributions to Recent Trends in U.S. Agricultural Yields' in the February 14, 2003 issue of Science magazine. Lobell and Asner are currently working in the Yaqui Valley on integrating the remote estimates of NPP with a biogeochemical model (Terraflux) to simulate regional carbon fluxes. They are continuing to work on management applications of the remote sensing wheat yield estimates through management decision models and surveys.

• Yaqui Valley Conference, Sonora, Mexico - October 16-18, 2002

Twenty-five Stanford Universtiy and Mexican researchers gathered in Sonora, Mexico for the fourth annual Yaqui Valley Conference held October 16-18, 2002 to discuss the past present and future conditions of agriculture and aquaculture development in the Yaqui Valley

• Saving Ecosystems Through Satellite Imagery

  CIMMYT, with the assistance of Stanford Yaqui collaborators, are using satellite images to help researchers understand the ecology of intensive farming systems in Mexico. Their findings could have implications for similar systems in South Asia. Click here for further information
