World Relief Staff were trained by Dr. Darcy Boellstorff and Zaine Venter during the June trip in how to use GIS. The training manuals led participants through the process of using their survey data to answer questions about the location of special demographic groups (i.e. women-headed households with orphans) and to answer questions about spatial relationships between natural and man-made features of interest (i.e. road buffers, proximity to irrigation water, proximity to storage facilities, etc.). After completion of the three-day course, participants were given a certificate of completion.
A HOBO relative humidity/temperature and a precipitation gauge were added to the World Relief Office weather station.

During the June trip, Dr. Darcy Boellstorff, Zaine Venter and WR team met with potential collaborators including:
· Mr. P. Chikapa, the Assistant District Agriculture Development Officer in Mzimba
· Mr. Mkinda, the Mbawa Extension Planning Area (EPA) Team Leader
· Dr. Benesi, Government Plant Breeder at the Chitedze Agricultural Research Station in Lilongwe
· The technical assistants of Dr. Chipungu at the Bvumbwe Agricultural Research Station in Bvumbwe
· Melody McNeil – Agricultural Officer at USAID Malawi Mission
· Faculty from Bunda College of Agriculture
A training manual for using Quantum GIS and the survey database was developed for training World Relief staff in June. The manual exercises are geared to both introduce the user to GIS and to help understand the relationship and utility of the survey data in planning. Each exercise culminated in a finished-product map that were exported to a pdf format.
The exercises include:
The exercises include:
- Adding Vector/Raster Layers
- Map Composition Using Malawi Districts, Roads, Water Bodies/Rivers
- Compare Image Resolutions – New Shp, Digitizing And Editing Layers
- Find Widowed-Female-Headed Households That Have Dependents
- Find Female-Headed Households That Earn 50,000 Mwk Or Less Per Year
- Find Women-Headed Households That Earn Less Than 50,000 Mkw, That Are Not Within A 20 Minute Walk Of A Storage Facility
- Farm Area - Rainfed Land
- Root Growing Rainfed Farms Near River Irrigation Source

The data from the farmer surveys were coded and organized into 13 relational tables which can be joined to their spatial location using a common item called “Survey_ID”. The tables were stored as Excel files and also as .dbf files for joining in Quantum GIS. Metadata attribute tables were written that allow users to look up attribute definition and value codes.
