Linkage of Drought Group Activities with Demonstration Projects

Current Status

• Developing a DATA bank
• Collection of Meteorological & Hydrological parameters
• Routine soil moisture observations (filling the data

gaps)

• Planning to move forward with practical approach
• Making efforts to show the system adaptable in

member countries

Scientific Supporting Team

• To advise on choice of RS Data sets for retrieval of soil moisture and

develop algorithms

• To integrate in-situ and RS soil Moisture data and meteorological

data

• To analyse data sets for drought in relation to demonstration projects
• To incorporate results in adaptive activities of Dem Projects
• To prepare drought monitoring indices and demonstrate software
• To make use of numerical products and GCM output
• To present a trial early warning system

Data Situation

A.Soil Moisture/Soil Temperature

Bangladesh: 9 soil moisture stations, weekly data for 5 layers China: Shanxi Province, 108 stations, Met and ST data 6hour, SM per 10 days, 3 layers Mangolia: 3 stations at Mandalgobi, Deren, Bayantsaagan since 2001, A half hourly and/or hourly automatic measurement Pakistan: 4 stations (Rawalpindi, Faisalabad, Tandojam and Quetta), SM per 10 days, for 10 layers at 10cm interval upto 1m depth. Veitnam: Only one Soil Temp station (Phan Thiet), 4 times/day ; no soil moisture

(10°34'13"N - 11°37'30"N,107°23'30" E- 108°52'30"E)

3 Surface Stations (Phan Thiet: 11°56' N- 108°06‘E,

Phú Quý: 10°36‘N - 108°56‘E, La Gi: 10°40‘N – 107°46‘E); P, T, R, RH, 4 times/day ;

China, Mongolia and Pakistan have also started reporting

meteorological data

Remo mote Sensing Data Sensing Data

Microwave: AMSR-E (Dr. Kaihitsu and Dr. Wen), AMSR-E

SM products from JAXA and NASA are used

Optical: MODIS (Dr. Orn-uma Polpanich, Dr. Ghulam

Rasul)

Data duration needed for retrieval and validation

Jan 2006-Dec 2007

Supplementary Data

Information of soil physical parameters including

Soil texture, Soil type, Porosity, Saturated hydraulic conductivity, Bulk density, etc.

Retrieval of Soil Moisture Data

Choose the two typical areas (getting the algorism) in Asia: Dry climate

condition: Mongolia, Pakistan; wet climate condition: Bangladesh, Vietnam and Thailand

Besides the AMSR-E data used by Prof. Kaihotsu and Prof. Wen,

MODIS data is used by AIT group.

Retrieval of SM data in two typical areas (Mongolia and Bangladesh) After the retrieval of SM data in Mongolia and Bangladesh, SM

products will be extended to Shanxi province of china and Pakistan

• Dr. Ailikun and Jie WEI are trying to get drought indices by using AMSR-

E soil moisture products

Addressing W Addressing Wat ater r Quality Issue Quality Issue

Increase in temperature, in addition to other effects,

will cause sea level to rise.

Intrusion of sea water inland will deteriorate the

quality of surface and ground water

Also the increased occurrence of intense rains, will

generate heavy loads of eroded soil

Water quality for drinking water supply may be

compromised due to high cost of filtration.
