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) 2 See for example – FAO FIVIMS http://www.fivims.org/ and World Bank sites http://data.worldbank.org/indicator?display=maphttp://www.fivims.org/http://data.worldbank.org/indicator?display=map

Stitch in time saves nine Spatial data and systems can help inform where the stitch is needed and the type of stitch required 6

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) 7 Solution ? Develop sustainable farming systems that improve efficiency gains to produce increased food production
8
One Billion People Suffer Chronic Hunger and Poverty 8
9
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 9 Trends in maize shortage in Zambia Percentage of farm households with maize shortage The Hunger Period

11
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. 11

Needs Requires a strategic approach, an appreciation of scale, and an understanding of the interactions between and within systems 13

The current ACIAR SSA Farming Systems project Builds on the work of Dixon et al 2001 14 www.fao.org/farmingsystems/
15
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 15

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 18
19
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 19 Challenge
20
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 20
21
Methodology Work in collaborative fashion with authors and other large data providers e.g. IFPRI – Harvest Choice, UN-FAO, ILRI, ICRAF, IIASA, CGIAR others 21 Delineate new Farming System Boundaries – Iterative process based on concept of central tendency Statistics and Analysis Characterise and describe systems
22
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 22

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 26

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 27

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 28
29
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 29
