Australian Centre for International Agricultural Research ACIAR Spatial Data and Analysis in Support of Improved Policy and Planning – An ACIAR example using Africa Christopher Auricht chris@auricht.com ACFID Canberra 21 August 2012
Current status of spatial data and applications • Applications now matured to point where such systems: • Can and are being used in various capacities. For example - • Humanitarian scenarios (especially as they relate to malnutrition, morbidity and mortality) • Economic scenarios with and without interventions at differing stages i.e. decision support systems e.g. pre-emptive, resilience building / risk management interventions v’s emergency response triggered by high mortality or threat i.e. once a crisis has eventuated • Have ability to look at multiple scales( local, national, regional) and longitudinally (forwards and backwards) See for example – FAO FIVIMS http://www.fivims.org/ and World Bank sites http://data.worldbank.org/indicator?display=map

Talk outline – Sub-Saharan Africa Example • Context and Background • Need for a strategic approach • Issues and status of spatial data • Methodology used in developing an updated farming systems dataset and analysis for Sub-Saharan Africa • Food Security and Nutrition AIFSC
Stitch in time saves nine • Spatial data and systems can help inform where the stitch is needed and the type of stitch required
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 (often 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
Scale of Rural Hunger Trends in maize shortage in Zambia Percentage of farm households with maize shortage • Nearly one billion people experience debilitation, health-threatening hunger each year • 4 out of 5 of these people are rural farmers The Hunger Period
Background • ‘Business-as-usual’ investments in agriculture unlikely to deliver sustainable solutions in many countries • Numerous obstacles to progress e.g. inefficiencies in program delivery, political uncertainty etc. These are not the only problem! • Existing systems (often under stress) have been/ are expected to continue to accommodate large increases in population, increasing urbanisation, rising demand for animal products, plus competition for land and water • Forecasts suggest 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
The current ACIAR SSA Farming Systems project www.fao.org/farmingsystems/ • Builds on the work of Dixon et al 2001
2001 Farming Systems and Poverty • Widely accepted as pioneering body of work – looked at things as a ‘surface’ across landscape not confined by country borders – often problems are regional • Largely driven by LGP/AEZ and market access, supplemented by expert opinion • Extensively used to guide investment at the program level and frame analysis in numerous global studies • 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
Sub-Saharan Update • Is there a demand for this information? Farming systems website in FAO still one of the most visited sites within the organisation – up to 4,000 hits per month (Site > 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. climate, population, urbanisation, market access, economics etc. • Many updated and new datasets available
Challenge • Capture and use data and information in an manner that informs decisions in a simple fashion • Maintain rigour and transparency • Establishing an enduring infrastructure/framework to enable changes to be monitored over time • Ability to support numerous policy initiatives – Principle: collect it once – use it many
Current Situation • 2012 – Large quantity of potential datasets – approx. 300 alone in the Harvest Choice database temporal and some predictive data now available • GAEZ 3.0 - 1,000’s of datasets representing 100’s of thematic layers • Question - which ones to use and how • Strategic approach • Access and collation • Assess (fit-for-purpose) and Prioritise (currency, coverage, scale etc) • Process Products • Disseminate
Methodology Delineate new Farming System Boundaries – Iterative process based on concept of central tendency • Work in collaborative fashion with authors and other large data providers e.g. IFPRI – Harvest Choice, UN-FAO, ILRI, ICRAF, IIASA, CGIAR others . • Characterise and describe systems Spatial and Tabular Data Statistics and Analysis
Approach • Integration of new datasets – • LGP and Market access • Supporting Datasets • Population (rural, urban, total) • Livestock – cattle, sheep, goats, poultry, LU and TLU • Crop areas and production • Yield gaps • Protected areas • Poverty $2.00 and $1.25 /day • Nutrition

Big questions for management and policy • What is it? • Where is it? • What are its characteristics and how does it operate ? • What are the risks/threats ? • What are the opportunities (Research / Extension) ? • How are these issues changing with time ? • Evaluation and Performance
Spatial data • Tool to support process • Understand • Analyse • Develop interventions • Monitor • Not the answer in itself • has limitations • Fit for purpose • Complement with expert knowledge
Spatial data and ACIAR Activities • Update of Farming Systems for Sub-Saharan Africa • Informing development of policy and program development as part of the ACIAR ‘Australian International Food Security Centre (AIFSC)’ • Announced by Prime Minister Gillard October 2011- International focus, recognising the significance of food security to developing countries. • Providing a bridge between agriculture (technologies, policies and practices) and their adoption by smallholder farmers (including livestock keepers). Increase adoption increase productivity and diversity and generate additional income
AIFSC • Research gaps in terms of food security, agriculture and nutrition in line with the AIFSC strategy and African priorities • Support in determining how AIFSC could best complement work being undertaken by partners in target countries and where we should invest • Nutrition indicators – under-nutrition, child nutrition, maternal under-nutrition, micronutrient deficiencies • Nutrition interventions , regional analysis, country snapshots
