Livestock are part of an economic system therefore the evaluation of the burden of animal disease must be placed in an economic context that captures livelihood and wider economy impacts as well as externalities related to the environment and human health.
The complexity of this endeavour requires it to be broken into themes which are linked and highlighted below. GBADs will assess the location and importance of the livestock Populations and Production Systems, collecting and collating information on the input and output relationships of livestock production. This information will be the basis for estimating the health loss envelope for different species and production systems (Production Loss and Expenditure) due to the presence of disease and other health or nutritional problems.
The health loss envelope will be attributed to specific causes of disease, based on existing knowledge and new studies, adjusted for co-morbidities and other health problems through careful Animal Health Ontology and Attribution. The health loss envelope will include information on production loss and expenditure at farm-level and will be used as a parameter to determine the wider societal impacts of the disease through modelling work (Wider Economic Impacts and Trade). Additional information on the direct and indirect impacts on Human Health will also feature. The data and information generated will be held in a secure Informatics system which will enable modelling for Disease Prioritization as well as tools for the effective communication of results. Each theme will be supported by Engagement with countries, Private Sector and NGOs through the collection of animal production and health data and information sharing for animal health decision making. Alongside each theme will be a process of institutionalizing the GBADs methods through an education programme (Education and Communication); this will result in a global knowledge framework to assess the impact of animal disease and health problems in livestock. These education programmes will be supported by the development of a code of practice for using biological, disease and economic data for assessing animal disease impacts and a guide on livestock population estimations and their classification by species and production system (Policy and Institutional Environment).
GBADs will build on existing data collection systems such as OIE-WAHIS and FAOSTAT, Bill & Melinda Gates Foundation’s investments in data collection analysis such as SEBI and GALVmed, plus private sector databases and combine the data with other relevant datasets and sources. GBADs will work with international organisations, international finance organisations and associated development banks, regional actors, national governments, NGOs and private companies to ensure continued stakeholder engagement.
