  1. Agro-MAPS A global spatial database on sub national agricultural land-use statistics

  2. Land use (LU) “..human activities which are directly related to land, making use of its resources or having an impact on it ...”FAO, 1995 • Socio-economic purpose of the activities (functional definition) • Usually multiple purposes • Manipulation of natural ecosystems in order to obtain benefits • Material benefits/ products (e.g. cereals, livestock) • Immaterial benefits/ services (e.g. erosion prevention) • Often some unwanted impacts!! Outputs Management Inputs What is the land used for? production vs. extractive process

  3. Why we need LU information • Land resources are finite & usually scarce! • Competition among various land uses (e.g. urban expansion into agricultural areas) • Different land uses affect the natural equilibrium of ecosystems differently - dissimilar impacts on the sustainable flow of goods & services • Thus, knowledge of current LU (& land resources) is needed for formulating changes leading to sustainable use of the resources LU – Key input for planning & policy formulation • national regional/global scales

  4. Local development issues • Zambia • Cited in NEAP: • Land degradation • Deforestation (Zambia 2.4%/yr – FRA 2000) • Air pollution & acid rain in mining areas • Water pollution & inadequate sanitation • Wildlife (game & fish) depletion • Most recent country wide LU information – 1975 • Focus of ILUA (integrated land use assessment) initiative Source: 2nd Zambian National report to UNCCD

  5. Environmental conventions • The Convention on Wetlands (Ramsar Convention), 1971 • Programs to conserve and use wisely all wetlands; 137 Parties; • Convention on International Trade in Endangered Species of Wild Fauna and Flora, CITES 1975 • To safeguard species from over exploitation; 164 parties; Appropriate wildlife management & trade policies • Convention on Biological Diversity, CBD 1992 • 187 Parties; biodiversity conservation • UN Framework Convention on Climate Change, 1992 • Kyoto Protocol (joint implementation, CDM, emissions trading) • UN Convention to Combat Desertification, UNCCD, 1994 • Programs to reduce degradation of land in arid, semi-arid and dry sub-humid areas; 166 Parties;

  6. LU information requirements

  7. Status of available data - 1 Regional/ global data • Crops FAOSTAT; IFPRI • ForestsFAO (FRA) • Water AQUASTAT, U. Kassel • Cultivation intensity NASA • Eco systems USGS • Protected areas UNEP-WCMC • Land cover/use FAO(Africover); USGS; IFPRI; SAGE; LUCC; MA; GLC2000; Global Mapping; Shortcomings: ± limited coverage / number of classes; non-standard definitions; insufficient information on management aspects; insufficient detail; modelled data

  8. Food security & poverty Land degradation Climate change Policy formulation Land use planning Investments in sustainable agriculture .. Status of available data - 2 Insufficient agricultural land use information needed to examine national, regional & global issues TOPICAL ISSUES

  9. Agricultural land use How? Management: inputs, technologies How much? Quantities: areas, products, .. What? Objectives:Products, services When? Timing of operations Where? Location & spatial extent Why? eg. reasons (biophysical, socio-economic,.) Major characteristics of agricultural land use Versus Land cover... the observed (bio)physical cover on the earth’s surface (LCCS, 2000)

  10. Agro-MAPS database contents How much? Quantities: areas, products, .. • Statistics aggregated by sub-national administrative districts. • crop production • area harvested • crop yields What? Objectives:Products,services Where? Location & spatial extent Major contents of the Agro-MAPS database

  11. FAO Contributors to Agro-MAPS SAGE Map source: CGIAR IFPRI • Global data base; subnational; geo-referenced; • Pooled contributions (FAO, IFPRI, SAGE, CIAT, ..)

  12. Compilation - tabular statistics FAO codes area harvested barley production Spelling; name changesredistricting Boundary file codes;SALB Missing; not available; zero; validation vs FAOSTAT • Data from diverse sources; IPR issues • Harmonization; accuracy!!

  13. Compilation of boundaries MALAWI FAO IFPRI • Differences in 2nd level boundaries from different secondary sources • Boundary disputes • Coding scheme

  14. Matching statistics to boundaries Challenge: Find the right map!

  19. Food security & poverty Land degradation Climate change Policy formulation Land use planning Investments in sustainable agriculture .. Potential for expansion of agricultural areas ratio of cultivated to cultivable land Potential for intensification Ratio of harvested to cropland areas Ratio of cultivated land to fallow land agricultural land under irrigation Sustainability arable and permanent cropland area (the cropland area used for food production) (UNCSD indicator) Applications of Agro-MAPS data Indicator analysis – (e.g. monitoring progress - MDG Goals) Goal 1: Eradicate extreme poverty & hunger Goal 7: Ensure environmental sustainability SELECTED INDICATORS from Agro-MAPS TOPICAL ISSUES

  20. Reponses Driving forces Pressures Impacts State Land degradation assessment Macro-economic policiesLand tenure policies Conservation/ rehabilitationEarly warning systemsInvestments Macro-economic policies Growth in population, incomeLand use Land tenure Poverty Natural disasters LADA project Ecosystem Approach Relationships: DPSIRDecision making tool Agro-MAPS data • Poverty & migrationReduction in products & services • Carbon sequestration • Water quality; biodiversity • Habitat destruction • Rising demands • Agriculture sector: products / inputs - over grazing - nutrient mining • Waste disposal

  21. Indicators: pressure • Percentage of agricultural land under exploitation • % of agricultural land used for crops (annual/ permanent) • Agricultural area per crop (cereal, oil crops, forage, woodlands) • Number of hectares of agricultural land per farmer; arable land per capita • Size of agricultural land under irrigation • Ratio of cultivated to cultivable land • Ratio of cultivated land to fallow land • Increase in cropping intensity (harvested areas/total cropland) • Agricultural area (intensely farmed, semi-intensely farmed, and uncultivated) • Increase in percentage irrigated area to cropland area • Percentage of cultivation on open access land, common property and private property • Land use (e.g. cultivated areas) in areas of high erosion potential

  22. Indicators: State • Ratio between actual and estimated crop yields • Land productivity adjusted for input use. • Net nutrient extraction in cropland, pastures, and forests • Number of crops under cultivation (>100ha) (bio-diversity) • Number of rare/minor crops under cultivation (>100ha) (biodiversity) • Area of each crop (biodiversity) • Number of cultivars per crop (biodiversity) • Area of each cultivar in a given year or period (biodiversity) • Crops (livestock) grown as a percentage of number 30 years beforehand • Number of key crop varieties (domestic, non-domestic) • Value of Production (VoP) per hectare of cropland

  23. Indicators - Response • Decentralized local-level NRM involving key stakeholders • Environmental impact statement requirement • Government spending in rural infrastructure (e.g. wells) • Subsidies to agricultural production • NGOs’ programs and actions plans • Number of land titles given • Increased access to non-traditional sources of energy • Percentage of protected areas of different ecosystems • Percentage of rural population having access to extension services • Farmers served by soil conservation programs • Use of techniques for soil improvement/ conservation • Changes in input use/ management practices (fertiliser, irrigation, genetic improvements, conservation agriculture,..); • Increase in access to credit for switching to better management practices • Environmental protection expenditures

  24. Zones at risk to degradation Comparison: • Soil suitability - Results of agro-ecologic studies • Agro-MAPS data on actual land use Agro-MAPS GAEZ Cultivation potential for rain-fed grain maize production (intermediate input level) Améliorer: Répartition selon les zones des cultures au lieu des unités administratives
