Facts According to CGIAR analysis
One billion of the worlds poor within Africa and Asia (those living on less than $1 per day) are fed primarily by: hundreds of millions of small-holder farmers (most
with less than 2 ha of land, several crops, and a cow or two), or
Herders (most with fewer than five large animals)
Solution ? Develop sustainable farming systems that
improve efficiency gains to produce increased food production without using more land, water or other inputs

One Billion People Suffer Chronic Hunger and Poverty

Scale of Rural Hunger Nearly one billion people experience debilitation,
health-threatening hunger each year 4 out of 5 of these people are rural farmers

Background Business as usual investments in agriculture unlikely
to deliver sustainable solutions in many countries Numerous issues often identified as barriers to
progress e.g. inefficiencies in program delivery, political uncertainty etc. These are not the only problem!
Existing systems (often under stress) have been, and are expected to continue to accommodate large increases in population, increasing urbanisation, rising demand for animal products and competition for land and water
Forecasts suggesting that current practices will not stay abreast with population growth, environmental change and increasing demand for animal products.

Needs Requires a strategic approach, an appreciation of
scale, and an understanding of the interactions between and within systems

2001 Farming Systems and Poverty Global study – part of the World Bank Rural Sector
Review Widely accepted as pioneering body of work Been extensively used to guide investment at the
program level. Approach focused on high level farming systems
within six developing regions Involved use of various thematic data layers to
underpin the delineation, characterisation / description and subsequent analysis of systems
Supplemented by expert opinion
![Page 11: Spatial Data and Analysis in Support of Improved Policy and Planning](https://reader035.vdocument.in/reader035/viewer/2022062810/56815c66550346895dca74ed/html5/thumbnails/11.jpg)

Sub-Saharan Update Farming systems website in FAO still one of
the most visited sites within the organisation
Previous study 10 years old Consistent seamless datasets somewhat
limited in original work In need of updating as spatial extent of
systems and frame conditions changed e.g. population, urbanisation etc.
Many updated and new datasets available
![Page 12: Spatial Data and Analysis in Support of Improved Policy and Planning](https://reader035.vdocument.in/reader035/viewer/2022062810/56815c66550346895dca74ed/html5/thumbnails/12.jpg)

Current Situation 2012 – Large quantity of potential datasets – approx. 300
alone in the Harvest Choice database longitudinal and some predictive data now available
GAEZ 3.0 - 1,000’s of thematic datasets representing 100’s of layers
Challenge – which ones to use and how Strategic approach
