1 REVIEW OF CURRENT AGROMETEOROLOGICAL APPLICATIONS AND FUTURE POTENTIAL IN URUGUAY AND FUTURE POTENTIAL IN URUGUAY (MSc) Mario Bidegain Dirección Nacional de Meteorología Uruguay Regional Technical Meeting on CLIPS and Agrometeorological Applications for the Mercosur Countries July 2005, Campinas – Sao Paulo - BRAZIL

2 Country background Uruguay is located in the south-eastern part of South America, located between 30° to 35° South and 53° to 58° West. It is bordered on the west by Argentina, on the north and north-east by Brazil, on the south by the Río de la Plata, and on the east by the Atlantic Ocean, covering 176,000 km2. Montevideo, the capital city, and most of Uruguay’s population are located on the coast of the Río de la Plata.

3 Topography The country consists mostly (75%) of gently rolling plateau, interrupted at two points by low hilly ridges (maximum heigth 500 mts). The remainder of the country is fertile coastal lowlands, including a narrow coastal plain and the somewhat broader littorals of the Río de la Plata and Río Uruguay.

4 Cultures and productions Red: agriculture (maize, soybean, wheat and barley) Green: grassland and meat production Grey: Dairy production Purple: Fruits and vegetables Blue: Rice Yellow: Citrics Brown: Forest

5 National meteorological network

6 Agrometeorological products produced by D.N.M. (Dirección Nacional de Meteorología) (http://www.meteorologia.com.uy) Daily rainfall bulletin (web page) Decade, monthly and annual climate statistics. Climate maps (rainfall, mean and extreme temperatures, rainfall days, anomalies, etc.) (web page) Users tailored reports Water balance and soil moisture monitoring. Diagnosis of climate anomalies Forecasting of seasonal climate (web page) Routinely weather forecasting (web page)

7 Agrometeorological products produced by I.N.I.A. (National Institute for Agriculture Research) Climate monthly maps of accumulated rainfall, and anomalies. (web page) Water balance and soil moisture monitoring. (web page) NDVI monthly vegetation monitoring (web page)

8 Regional and National research related to agrometeorology 1.Projects funded by the Inter-American Institute for Global Change (IAI) ISP II 1997 – 2000 Climate Variability and Agriculture in Argentina and Uruguay: Assessment of ENSO Effects and Perspectives for the use of Climate Forecast. Countries: Argentina – Uruguay – USA CRN Development of a Collaborative Research Network for the Study of Regional Climate Variability, Changes and Prediction in the MERCOSUR Area. Countries: Argentina – Brazil - Paraguay - Uruguay – USA SAAC: An International Consortium for the Study of Global and Climate Changes in the western south Atlantic. Countries: Argentina – Brazil - Uruguay – USA 1.Project funded by INIA (Uruguayan Government and Private Sector) FPTA Applications of Climate Forecast in the agricultural Sector 3. Project funded by MVOTMA (Climate Change Unit) Developed of Climate Change scenarios at regional and national scales

12 IAI CRN N°055 “Development of a Collaborative Research Network for the Study of Regional Climate Variability, Changes and Prediction in the MERCOSUR Area” Higher maximum extremes (above 35° C) values during cold ENSO phase, produce a increase probability of temperatures over threshold, and higher chance of warm spells during summer. Lower maximum extremes (above 35° C) values during warm ENSO phase, reduce the probability of of warm spells during summer. Lower minimum extremes (below 0° C) values during cold ENSO phase, produce a increase probability of temperatures below zero (frost), and shorter frost free period and higher chance of an later frost in the year. Higher minimum extremes during the warm ENSO phase produce lower amount of days with frost, longer frost-free period and lower probability of early and later frosts.

13 IAI CRN N°055 “Development of a Collaborative Research Network for the Study of Regional Climate Variability, Changes and Prediction in the MERCOSUR Area” Numerical Weather Prediction with WRF mesoscale model

14 Project UNDP “Development of climate change scenarios at regional and national scale” Changes in Precipitation 2050 (%) Changes in temperature 2050 (° C) Changes in Precipitation 2050 (%) Changes in temperature 2050 (° C)

15 Future potential use of agrometeorology information Operational rainfall estimation (satellite and observed) at higher scales (4 x 4 km) Improved climate seasonal forecasting (better climate models and “ensemble” techniques) as input for yields models. Improved weather forecasting at meso and local scale (< 15 km) Improved grain production models (ex. DSSAT) for simulate yields Use of grassland models (ex. SPUR) for milk and meat production Improved satellite images for use in vegetation monitoring and flood areas (ex. MODIS) New improved climate change scenarios at mesoscale (ex. PRECIS)
