  • 1. Optical and Microwave Remote Sensing for Crop Monitoring in Mexico J. Soria-Ruiz. National Institute of Forestry Agriculture and Livestock Research. Y. Fernández-Ordóñez Colegio de Postgraduados. H. McNairn Agri-Food Canada Beyond Diagnostics: Insights and Recommendations from Remote Sensing Workshop CIMMyT. Mexico, D.F. Diciembre 14-15 de 2013
  • 2. Optical and microwave remote sensing for crop monitoring in Mexico. Outline  RS in everyday life  Some applications realized by INIFAP  Extreme events: Flooding with SAR; Hurricane damage using SPOT5; Frost damage with MODIS.  Avocado Sunblotch Viroid (ASBVd) detection in Michoacan, Mexico using QuickBird.  Land Use/Cover in central Mexico using LANDSAT and SAR (Radarsat 1).  Crop monitoring, condition and crop yield using SPOT 5 and Radarsat 2. 2
  • 3. Remote Sensing in everyday life The human visual system is an example of a remote sensing system in the general sense. Currently, RS has become important with the advancement of space technology, with new elements of data gathering and analysis that contribute to solve many problems of today's society. 3
  • 4. Some applications realized by INIFAP Extreme events Natural phenomena become natural disasters when they surpass a normal threshold. Severe effects occur when planning and security measures are deficient. Mexico’s southeastern region is characterized by the economic potential of its natural resources. However, this region faces frequent cyclic problems due to natural disasters. 4
  • 5. Some applications realized by INIFAP Extreme events: Flooding Flooding in the state of Tabasco in October 2007 was considered the worst in 50 years. Excessive rainfall in the state of Chiapas and the rise of water levels in the Usumacinta and Grijalva rivers result in severe flooding in urban and flat areas. DEM - Tabasco 89% of its surface shows a flat topography with high flooding susceptibility 5
  • 6. Some applications realized by INIFAP Extreme events: Flooding Objectives To quantify the agricultural surface affected by flooding, for annual and perennial crops, with a Radarsat 1 image. Image Technical Specifications: • C-Band wavelength (5.6cm) • HH polarization (Horizontally transmitted and received) • Resolution: 12.5 m • Incidence Angles: 39º • Scene: 6 Nov 2007 ERDAS and Arc/Gis Software 6
  • 7. Results Affected agricultural areas
  • 8. Some applications realized by INIFAP Extreme events: Flooding 8
  • 9. Some applications realized by INIFAP Extreme events: Hurricanes Hurricane- a cyclonic low pressure system formed over the oceans and caused by water evaporation rising from the sea and becoming a storm. An increase in cyclonic activity has been observed in the equatorial zone of the globe; events are above the mean value of 9 cyclones per year. Objective Assess and quantify the agricultural surface affected by hurricane Dean in the three states of the Yucatan Peninsula. 9
  • 10. Some applications realized by INIFAP Extreme events: Hurricanes SPOT 5 mosaic used to assess damage in agriculture due to hurricane Dean in 2007. Affected areas of maize, sugar cane and agriculture plantations in Quintana Roo. 10
  • 11. Some applications realized by INIFAP Extreme events: Hurricanes Affected areas of maize crop - Yucatan Affected areas of maize crop - Campeche 11
  • 12. Some applications realized by INIFAP Extreme events: Frost MODIS Serious frost in Sinaloa, Northwestern Mexico, in late January 2011 caused a total loss of garden produce, vegetables and annual crops of the AutumnWinter agricultural cycle. (Assessment work carried out jointly by SIAP and INIFAP.) Before frost After frost 12

  • 15. Some applications realized by INIFAP Avocado Sunblotch Viroid (ASBVd) detection in the state of Michoacan QuickBird Avocado Sunblotch Viroid (ASBVd), a disease with economic consequences affects Avocado (Persea americana Mill.) Plantations affected with ASBVd exhibit yield reductions and lesser quality produce of up to 52.7 %. 15

  • 18. Quickbird Image Spatial resolution: 0.60 m
  • 19. Sampling and georeferencing of ASBVd infected trees
  • 20. Infected individuals resulting from the digital classification were validated via fitopatology lab tests. Precision: 87 %
  • 21. Some applications realized by INIFAP Land Use/Cover in central Mexico: Landsat ETM and Radarsat 1 the objective of this study was to assess the advantages of combining synthetic aperture radar (SAR) and optical remote sensing in producing more accurate maps. Landsat ETM 25 m 30/July/2001 Methodology SAR R1 Fine beam mode HH polarization C band (6.25 m) 16/Aug/2001 Incidence angle: 42.03 21
  • 22. Some applications realized by INIFAP Land Use/Cover in central Mexico: Landsat ETM and Radarsat 1 22
  • 23. Some applications realized by INIFAP Crop monitoring, condition and crop yield using SPOT 5 and Radarsat 2. In Mexico over two agricultural cycles (Spring-Summer and Autumn-Winter) 28.5 million tons are harvested. These crops require continuous monitoring in order to correct management deficiencies. Production systems for this crop are varied In the center and southern regions of the country production systems are characterized by small plot sizes, irregular forms and most of them on sloped terrain. 23
  • 24. Some applications realized by INIFAP Crop monitoring, condition and crop yield using SPOT 6 and Radarsat 2. Objectives 1. Study the utility of multi-polarized C-band radar data for crop type and crops condition in Mexico. 2. Establish the benefit of combining RADAR and OPTICAL data in increasing accuracy of crop condition. 3. Use quad polarization (QP) mode to increase detection of crop type and crop condition of corn, and ultra fine spatial resolution for crop yield from Radarsat 2. 4. For crop yield, assess the linear cross- polarization data (HV and VH) using contrast information and different incidence angles to establish areas of high and low productivity. 24
  • 25. Some applications realized by INIFAP Crop monitoring, condition and crop yield using SPOT 6 and Radarsat 2. Radarsat 2 C band 4.8 – 7.5 cm wavelength 8.0 - 5.0 GHz frequency RADARSAT-2 is a fully polarimetric sensor, thus it is able to send and receive radar waves in all possible polarization combinations: Horizontal (H) and Vertical (V). Thus the following polarizations are available: co-polarized radar signals (HH y VV) and quad-polarized signals: Selective Polarization: (HH and HV) or (VH and VV) Single Polarization: (HH) Quad-Polarization: (HH, VV, HV, VH) Selective Single Polarization: (HH) or (HV) or (VH) or (VV) 25
