2 OUTLINE Mapping, GIS and Spatial Analysis for Targeting
Political and Agroecological Units New Information for Targeting and Priority-setting Some directions for the Future

3 Mapping, GIS and Spatial Analysis for Targeting

4 Thematic Mapping of “Necesidades Basicas Insatisfechas”
at different scales in Honduras

5 Village-level mapping based on
multivariate statistical analysis in the Central Peruvian Amazon

6 Boolean Analysis Preliminary overlay of areas of high population density [shown in lavender, > 25 people/km2] and low rice yields [shown in yellow < 1.5 tons/ha ] Purple colors show areas meeting both conditions

7 Spatial Clustering Methods based on
village-level census data in Honduras

8 Fungicide Applications Model based on data

9 Political and Agroecological Units
Most interventions are carried out in countries, departments, municipios, villages Biological, soil and climate processes occur in agroecological zones Priority setting exercises should analyze conditions according to both political and agroecological units Significant improvements can be made by using information at higher spatial resolution (e.g. TAC priority setting exercises)

10 As a general principal, geographical targeting
Most interventions occur according to political units 10,400 units most are municipios Municipio (canton) level Parroquia level As a general principal, geographical targeting improves with greater spatial resolution (e.g. leakage)

Classification based on length of growing season

13 Modifiable Areal Unit Problem Population from Census
Improving socioeconomic data for further analysis Modifiable Areal Unit Problem - estimation techniques improve spatial resolution Accessibility Model of Population

14 Sum of errors when modeled population is compared to
Modeled population counts compared to actual census data for Peru Modeled estimates reduced overall error by one half in Peru Sum of errors when modeled population is compared to actual census data PERU

15 Population and Vegetation Types in Honduras
- with better resolution maps, we can more easily estimate population in vegetation zones CCAD Vegetation Map

16 Potential Agricultural Productivity
Population summed by zones Note: Areas en black are cities. Zones in Purple are higher rural population densities. Zones in green are low rural population densities. Raster Population Surface (digital map)

17 Agricultural potential in calories/ha/yr From a spatial overlay, we can estimate the number of rural people living in different classes of agricultural potential.

32 Some directions for the Future
Computational Geography Better data, and power to analyze it Combining Census and Survey Methods LSMS DHS Better Integration between the Social, Economic, Biological and Geographical

33 A relatively small investment in improved geographical targeting could yield large gains in poverty reduction
