This document represents the views of the experts of the Sino-Australia Joint Science and Technology Committee (JSTC) project group in the area of Environmental monitoring using remote sensing techniques and reports on the progress of the projects to the 3rd JSTC, and establishes an agreement to proceed on the Project areas listed.

BACKGROUND TO CURRENT MEETING

In April 1995, In order to start the 2nd round of the Sino-Australia cooperative project Monitoring Environment Using Remote Sensing Technique, according to the decisions of the 2nd JSTC, an Australian remote sensing technology delegation lead by Dr. B.J. Embleton, Head of CSIRO-OSSA, visited China. After a series of discussions and scientific investigations, Dr. B. J. Embleton and Prof Zheng Lizhong, the Deputy Director-General of National Remote Sensing Centre of China, signed the bilateral agreement on Monitoring the Environment Using Remote Sensing Techniques. This was pursued in four areas: Monitoring Soil Moisture and Drought Using Remote Sensing, Soil Erosion Mapping Using Remote Sensing, Mapping Water Quality Using Remote Sensing, Crop Yield Estimation Using Remote Sensing. At the joint meeting, cooperative exchanges and research programs were agreed to be carried out.

In November 1995, Prof Zheng Lizhong, the Deputy Director-General of National Remote Sensing Center of China, headed a Chinese Remote Sensing Science & Technology delegation to visit Australia. Through these means of attending academic conferences; holding bilateral talks; visiting research units and bilateral exchanges with scientists etc., in four fields above mentioned, the initial academic exchanges were carried out, and at the same time, the concrete cooperative interchange plans were worked out.

PROJECT REPORTS

Monitoring Soil Moisture and Drought Using Remote Sensing

The project Monitoring Soil Moisture and Drought Using Remote Sensing has achieved considerable success. This cooperative project is a continuation of the project Monitoring Soil Moisture and Drought Using Remote Sensing Technique of the 1st JSTC. In the cooperative research of the 1st JSTC project being carried (between 1995-1997), the Sino-Australia scientists performed experiments using models for monitoring soil moisture and drought using remote sensing technique which were developed by bilateral scientists in each counties experimental areas, and then, the advanced models were refined to be applied in experimental areas and the outstanding research results have been achieved.

This project was then supported by the 2nd JSTC, its objective to be brought into the new cooperative round is that based on the bilateral achieved results, the models will be implemented and seek applications, and then, the system of monitoring soil moisture and drought using remote sensing technique will be established in both counties and will be used to monitor the large area. After the three years' hard work between1995-1997, the bilateral scientists have significantly accomplished these ambitious and conscientiously anticipated project objectives. As this area involves public benefit-being aimed to improve the output of whole regions of the countries farm areas-the applications transfer have been to government agencies.

According to the project's objective, the scientists of Institute of remote sensing application, CAS, undertaking this project as being Chinese side, and the scientists of CSIRO, undertaking this project as being Australia side, worked out the plans to be carried out, discussed the division of work, interchange visit and academic exchange, participated the research work together, the achieved results following :

1. On the basis of energy balance theory, developed an infra-red remote sensing data model, and established the NDTI and CWSI to monitor soil moisture and drought.

2. Provided the method of area NDVI and monthly vegetation index and the method of soil moisture estimating using radar technique has been studied.

3. Sino-Australia both sides established the system of monitoring soil moisture and drought, these two systems are the integrated systems of RS; GIS and meteorological data analysis. This system includes background database; monitoring model; meteorological data analysis; NOAA AVHRR image processing; NDTI/CWSI mapping and results outputting etc.

4. Drought was monitored with the developed model and established system in China and Australia. China selected the Huang Huai Hai (or North China) plain as the monitored area, Australia selected the Murray-Darling river basin as the monitored area, drought history and current state was monitored using NOAA AVHRR data; CWSI and NDTI models and good results were achieved.

5. The project has significantly approached the anticipated objectives, and the project summary final report has finished, the two sides has written two main Technical Reports together, and are currently publishing three or four papers from the Technical Reports.

Crop Yield Estimation Using Remote Sensing Technology

Besides the Project of Monitoring Soil Moisture and Drought using Remote Sensing Technology, Crop Yield Estimation Using Remote Sensing Technology has also attracted a lot of interest among Chinese and Australian experts who have developed a substantial cooperation.

Chinese scientists have more than 10 years of research experience in large area crop monitoring by remote sensing. Relatively high yield estimation precision has been achieved. Nevertheless, some research areas in yield prediction, such as new type sensor and in-depth application of GIS, still need to be studied further. Australian scientists have done a lot of experiments in crop yield estimation by meteorological satellite and Landsat satellite data as well. They have also explored the use of radar remote sensing and GIS to prompt precision and expand estimation area. Therefore, the bilateral cooperation is mutually complementary. According to the time of fund allocation, the technical system and route defined by two sides will be realised in 1999. It can be applied in two different kinds of agricultural regions respecting to rough and intensive cultivation. So, it has value for technology transfer.

Considering the project objectives, Chinese scientists from the Institute of Remote Sensing Applications, CAS and Australian scientists from the Department of Geography, the University of New South Wales have conducted two periods of academic exchange during 1995 and 1996. The formal cooperation began in April 1997. The accomplishment of two times of workshop and field survey is as follow:

(1) Review and estimation are made to currently bilateral remote sensing methods of wheat yield prediction in order to lay the groundwork of defining technical route.

(2) An integrated research scheme is proposed to define the aim and contents, choose the common study areas, as well as determine division of labour of two sides and research time table during 1997 and 1999.

(3) Bilateral units in charge invite respectively the experts from Department of Agriculture of New South Wales State, Nanjing Institute of Geography and Natural Resources Survey Committee of CAS as well as National Meteorological Satellite Center of China. It plays an positive role in promoting understanding and improving research for the scientists of two countries.

Soil Erosion Using Remote Sensing

In the aspect of Research of Soil Erosion Using Remote Sensing Technique, academic exchange, which promote bilateral understanding, has been made between Australian Nuclear Science and Technology Organisation (ANSTO) and Department of Water Conservancy of China as well as Chengdu Institute of Mountainous Region of CAS. An fruitful exchange has been developed in the research of application of caesium 137 isotope technology in soil erosion study. This project is now completed.

Inland Water Quality Using Remote Sensing

As for Research of Inland Water Quality Using Remote Sensing Technique, the units in charge are CSIRO Earth Observation Centre and Remote Sensing Center of Chinese Department of Water Conservancy. They share identical understanding in high spectral remote sensing research and applications and sought to extend and develop the cooperation by including visits and exchanges as a pilot study in coastal and ocean water quality. As a result of the studies made, a re-assignment of priorities has taken place to the ocean and coastal resources and the emergence of the Ocean Colour Validation project listed below for the new round of the JSTC. The development of priorities and activities was achieved by visits to Australia by Mr Tang Junwu of the Institute of Ocean Technology (IOT) to review ocean and coastal optical water quality research in Australia and a visit to the IOT by Dr David Jupp to introduce Australian work in Optical Water Quality and coastal and marine optical techniques. Mr Tang's report was tabled at the 3rd JSTC Meeting. The Australian side interaction was coordinated through a newly formed Australian Ocean Colour Working Group which has allowed the Australian side to include a wide range of institutes.

Summary

In summary, three years of collaboration and exchange have been highly effective. We are inspired by the achievement of the scientists of the two sides. To the next stage of cooperation, bilateral remote sensing organisations and experts have made suggestions as follow:

PROJECTS CONSIDERED IN THE CURRENT JSTC MEETING

The experts group has met and considered reports from the 2nd round of the JSTC and new project proposals from both countries. The SSTC discussions for the new round were lead on the China side by Prof Zheng Lizhong, the Deputy Director General of National Remote Sensing Center of China and the Australia side by Dr David L B Jupp of CSIRO Earth Observation Centre. The Projects discussed in the current JSTC Meeting have been grouped into three areas of application: Sustainable Agriculture, Ocean & Coastal Remote Sensing and Land Use & Land Cover Change.

Sustainable Agriculture:

Sustainable agriculture is vital to the food security and income protection of both countries. In both countries water is limited resource and yield must be achieved in a sustainable but maximal way. The efficient and maximal use of water resources in production of crop yield is a key issue for both countries.

Sub-Project 1: Crop Yield Estimation Using Remote Sensing Technique between UNSW in Australia and NRSCC in China, which just complete the first year's cooperation and exchange content, still need two years to continue. We recommend it be listed into the forward projects of this JSTC and get support from two governments as before.

Sub-Project 2: Monitoring Soil Moisture and Drought Using Remote Sensing Technique between CSIRO Division of Water Resources and Institute of Remote Sensing Applications CAS has executed for six years and obtained very good results. The proposed evaluation of the methods using the accumulated data resources of the projects is recommended to occur as a continuing Program.

Sub-Project 3: Workshop on Remote Sensing for Sustainable Crop Yield and Water Use Between Australia CSIRO, China NRSCC and CAS. At the conclusion of the evaluation we plan to hold a workshop in Australia to conclude its fruits. Because this project area is still an important study area relative to the agricultural development for China and Australia, we suggest to go on listing it (Sub-Project 2) and the Workshop to the projects of the 3rd JSTC to continually get progress.

Ocean & Coastal Remote Sensing

A topic of special concern to both countries is surveying ocean environment and resources by remote sensing technology. The interests are based on the importance of its resources development and environment protection. In China the 863 Program is evidence of the importance and in Australia and China ocean resources are vital sources of income and food. We can develop a broad cooperation in this area. Projects listed are:

Sub-Project 1: Ocean Colour & Fisheries. We have defined a project on ocean colour and fisheries by remote sensing groups of institutes in China and Australia. In China, the Institutes involved are the NRSCC as lead agency, the Institute of Ocean Technology, the South China Sea Institute of Oceanology and the Shanghai Institute of Fisheries. In Australia, members of the Australian Ocean Colour Working Group (AOCWG) especially CSIRO Marine Laboratories, AIMS and Curtin University are identified. This project can be listed into the projects of current JSTC due to its level of bilateral development in the Optical Water Quality work of the last JSTC.

Sub-Project2:RemoteSensing Technology Development for Ocean Monitoring This is listed as a major developing project area which will seek through meetings and a workshop/study visits in China and in Australia respectively on Ocean Instrument Measurement Technology to be established in the future. Visits by a selected group of experts from a range of institutes in the two countries will occur with existing funds leading to future projects and interaction. The detailed arrangement of this mutual exchange is that, for discussions and workshop/study visit, Chinese group will visit Australia in Australian Autumn of 1998 and an Australian group visit China in the Chinese Autumn. Discussions will be based on suggestions made to the current JSTC and include instrumentation development, information systems and altimeter data analysis and assimilation.

Land Use and Land Cover Change

As China and Australia are both big countries, it is significantly important to do contrast research of large scale environment change between two countries by dynamic mapping using remote sensing technology.

Sub-Project 1: Environmental monitoring using Synthetic Aperture Radar (SAR) to estimate forest and woodland biomass. This project has identified partners in China (Chinese Academy of Forest Sciences) and Australia (UNSW) and it is recommended that it seek to develop a work plan and sources of funds as part of this round of the JSTC.

Sub-Project2: Study on Land Cover Change using Remote Sensing Technology. This study has been proposed to coincide with transects which focus on the IGBP/HDP (Human Dimension Program). It may involve Australian groups from Griffith University (Prof Larry Crissman) and China CAS but will need further Australian collaborators to be complete. It is highly recommended to be developed and seek funds for future consideration by the JSTC.

SUMMARY FOR 3RD JSTC

In summary we recommend that ongoing and accepted projects with sufficient funding in China and Australia to proceed (but with further enabling and infrastructure funding in Australia to be sought) are Sustainable Agriculture Sub-Projects 1, 2 and 3.
