Management Responses to Seasonal Climate Forecasts In Cropping Systems of South Asia's Semi-Arid Tropics
In addition to the aforementioned APN funding, additional support came from the International START Secretariat. The Department of Primary Industries, Queensland, Australia (DPI), the International Research Institute for Climate Prediction (IRI, USA), Tamil Nadu Agricultural University (India), the Indian Institute of Science, the Indian Institute of Tropical Meteorology and the Pakistan Agricultural Research Council all provided substantial in-kind contributions of scientific staff time and training materials. The project is also known as a 'CLIMAG demonstration project'. The project is designed as a scoping study and constitutes a stepping-stone towards a well-integrated research and delivery program that will address more comprehensively those aspects of climate risk that currently impede agricultural production in developing countries. Using locations in Southern Asia as case studies, this project demonstrates the utility and feasibility of combining seasonal climate forecasting with a structured, agricultural systems research approach based on simulation modelling. The project provides the means to assess the potential value of seasonal climate forecasting to agricultural producers in the Asia-Pacific region. The specific objectives of the project are:
In addition to a range of publications currently either in press (eg. H. Meinke, W. Baethgen, P.S. Carberry, M. Donatelli, G.L. Hammer, R. Selvaraju, and C. Stockle, 2001. Increasing profits and reducing risks in crop production using participatory systems simulation approaches. Ag Systems) or in preparation, the following outcomes resulted directly from project activities: 1) Visits by Drs Meinke and Hansen to project sites in India and Pakistan Pakistan The purpose of this meeting was to bring Dr. Aslam up-to-date on project objectives, approaches and the tasks required to achieve the objectives of the project. A PhD student is conducting research on wheat/mungbean rotations (Ms. Raazia Durrani). Ms. Durrani has been collecting field data that appears to be well suited to test simulation model performance under Pakistan conditions. It was agreed that Dr. Aslam would participate at the workshop in Toowoomba (6 to 17 November 2000). In preparation for this workshop we agreed to conduct an analysis of cropping options along a transect through a higher rainfall cropping region of Pakistan (Peschawar, Islamabad, Lahore); conduct climatic analysis of the long term rainfall data along this transect; obtain the necessary missing climate data for the 3 locations and prepare them in APSIM ready format; and develop a clear and concise outline of current cropping systems, including key management decisions and possible management intervention based on climate information. India At the progress review meeting (attended by Drs Gadgil, Selvaraju, Hansen, Meinke, K.N. Rao and Mr. P.R.S. Rao) a detailed work plan was developed. This was followed by field visits to collect the necessary background information and data needed for the systems analysis (Toowoomba workshop). A study area was selected about 150km north of Bangalore on the border between Karnataka and Andhra Pradesh. It stretches for about 50km and covers dry land and irrigated production as well as a range of soil types (marginal to fertile). Peanuts grown in the kharif season dominate the cropping system. With the help of Mr. P.R.S. Rao, meetings and field walks were conducted with two different farmer groups ('marginal farmers' and 'progressive farmers'). During these meetings a clear picture emerged about possible applications of seasonal forecasting under these conditions. Details have been recorded and will form the basis for the systems analyses that will be conducted during the Toowoomba workshop. This was followed by meetings at Tamil Nadu Agricultural University (TNAU), Coimbatore. Dr. Selvaraju organised several field trips that provided a wealth of information suitable for the scenario analyses. Based on the information gathered and the contacts made with local farmers, the project team selected 2 sites (villages) that differ in climate patterns, cropping systems and infrastructure development, namely Tiruchengodu and Naduvacheri. Important decision points such as crop choice in relation to duration and severity of dry spell between seasons were identified for analysis at the workshop. 2) Toowoomba workshop (6 - 17 November 2000) In addition to many Australian scientist who were invited as guest lectures,
the project sponsored participants were R. Selvaraju, Suluchana Gadgil,
K.N. Rao,
Based on the information collected at the project sites, simulation analyses were conducted that demonstrate the value of using seasonal forecasts for decision-making. Issues addressed ranged from the value of soil conversation practices to conserve soil moisture in Pakistan to the quantification of management responses of the peanut based cropping system to ENSO-derived climatic variability (including the economic value of the forecast based management practices over the traditional practices). The work is currently being collided and several manuscripts are in preparation. 3) Participation at the Training Institute on Climate Variability and Society in the Asia-Pacific Region (third week) This activity took place in mid February. It was an opportunity to showcase the results from this project and to discuss and decide on the future direction of the initiated work. Dr. Eileen L. Shea (sheae@ewc.hawaii.edu) is the leader of this APN funded sister project. This portion of the Training Institute will provide an opportunity to develop a collaborative regional research project, involving national case studies and a common protocol, dealing with climate forecasts, their transmission and use in the context of different farming systems and cultural settings.
