Improved understandings of the agricultural and range ecologies of semi-arid Africa require better information on the spatiotemporal distribution of domestic livestock across agropastoral landscapes. An empirical GIS-based approach was developed for estimating distributions of herded livestock across three agropastoral territories (around 100 km2 each) over a two-year period.

To support the introduction of operational radar forest monitoring systems in Indonesian a demonstration is executed at the Tropenbos study area in East-Kalimantan. Interest focuses on fulfilling information needs relating to land cover change, fire risk and fire damage monitoring, with main emphasis on early detection.

The world is witnessing a period in its history when the increasing socio-political upheavals are taking the lives of thousands, and destroying the natural wealth of our planet. Poverty and food insecurity are two key forces driving this destruction. These ongoing problems compound those already being posed by an increasing shortage of water, scarcity of productive land, an expanding population, and the threat of global warming.

Proceedings of a workshop held in Embilipitiya, Sri Lanka, 29th March 2001. Presents preliminary findings on malaria patterns and possible risk factors and describes the progress of IWMI research towards developing a risk map for Sri Lanka. It also contains presentations by Regional Malaria Officers, and other officials involved in malaria control, on areas of high malaria risk within their districts.

This working paper contains the proceedings of the workshop on ?Malaria risk mapping in Sri Lanka?implications for its use in control? that was held on May 25, 2001 at IWMI Headquarters in Colombo, which was a follow up to the workshop conducted on March 29, 2001 in Embilipitiya (Klinkenberg 2001). The workshop in Embilipitiya was organized at the local level to discuss the results of the malaria risk mapping work carried out by IWMI in the Uda Walawe region of Sri Lanka.

CIAT programmed this simple and flexible GIS tool to automate the creation of accessibility surfaces. Previously, these surfaces were laboriously created, step-by-step, using ArcINFO software from the Environmental Systems Research Institute (ESRI). You can install the Accessibility Analyst if you have the ESRI ArcView 3 software and its ArcView Spatial Analyst. From this page, you can download the extension and documentation, see case studies of the extension at work, and follow up links with other people working in the same field.
