Requirement for a GIS to support Forecasting

DSS facilitates incorporation and integration of a variety of information, relevant for modeling of locust population on spatial and temporal context on a common platform. It maximizes the opportunities for early intervention and management of locust swarms. Characteristically it is ergonomic with user interface to facilitate both data capture and analysis through a series of menus for accessing separate information management tools with data display on spatial context. It is desirable to bring together all the information sources used by forecasting and field staff to aid in decision making process. The characteristic features of the DSS are expected to be as follows (Healey et al, 1996).

i. Access to historical records of locust sightings and associated environmental conditions, with ability to cross-reference related events.

ii. Structured access to reference material for new and existing locust case studies the later being derived from sources such as the published Desert Locust Forecasting Manual (Pedgley, 1981).

iii. Rapid input and storage of accurately located sightings.

iv. Facilities to display and analyze locust events in the context of both current and antecedent environment conditions, both meteorological and vegetation-related.

v. Ability to compare the present spatio-temporal configuration of locust events, together with prior dynamics, to past analogue spatio-temporal sequences from previous plagues and recession periods.

vi. Interfacing between GIS and other analytical tools for modeling of locust development and migration.

vii. Capacity of handling historical locust data for analysis of past locust events and analogue development from previous upsurge based on similarity / matching index.

viii. Capability of handling raster, vector and descriptive data as well as comparison of multiple raster and vector maps for analysis of the relationships between locust events and bio-climate.

ix. Analysis of daily weather data for bio-climatic modeling for breeding, upsurge and duration of life stage.

x. Organisational requirements to meet in-house procurement standards for hardware and software.
