SIMLEZA Site Characterization for Eastern Province of Zambia

Zhe Guo, Carlo Azzarri, Beliyou Haile

SIMLEZA - Africa RISING Meeting 28-29 May 2013, Lilongwe, Malawi


Objectives

  • Understand the spatial pattern and heterogeneity

  • Choose appropriate data layers for stratification

  • Thus help

    • Better target interventions

    • Identify representative or otherwise appropriate action and control sites

    • Guide scaling-up/scaling-out efforts within, across, and beyond


Data Source: Naomi Kamanga and Walter Mupangwa (N=225)

Lundazi

Chipata

Katete

Includes farmers in innovation networks?


Review of Spatial Biophysical and Socio-economic Data Layers

; Afripop

  • Candidate data layers mapped to visualize their spatial distribution

  • Final layers aggregated by classes

  • Results will need refining


Little within spatial heterogeneity (based on Land scan but result is the same based on Afripop)


Spatial heterogeneity


Little within spatial heterogeneity


Little within spatial heterogeneity


Little within spatial heterogeneity


Spatial heterogeneity


Spatial heterogeneity


  • Spatial heterogeneity in rainfall and elevation

  • Correlation b/n spatial distribution of temperature elevation

  • Two data layers (9 classes) to stratify SIMLEZA districts


Final Layer 1. Rainfall

772 -850mm

851-950mm

951-1050mm

1051-1241mm


Final Layer 2. Elevation

369-700 m

701-900m

901-1100m

1101-2237m

Excluded area - No farmers in this range based on available farmer location


Final Classification


Conclusion and Caveats

  • Candidate layers – population, market access, temperature, LGP, slope, elevation and rainfall

  • Maps based on GIS location of 225 farmers from 7 camps in 3 districts

  • Final layers for stratification - elevation and rainfall; 9 classes

  • Site/Camp stratification:

    • Ludanzi (Hoya and Vuu): Low R - High E

    • Chipata (Kapara, Mtaya, and Chanje ): Low R and Medium E; Medium R and Medium E; Medium R and Low E

    • Katete (Kawalala and Kafumbwe): High R and Medium E

  • Coarse resolution metadata more suitable to global analysis


Next Steps

  • Update maps based on

    • Feedback from Zambia team

    • Higher-resolution/better data layers from Zambia team

    • Data for all farmers (e.g., could there more than 1 class in Ludanzi: low-low), including from Mesekra

  • Identification of target and control sites

  • Data collection efforts

    • Review of existing data

    • SIMLEZA baseline survey tool
