Africa RISING Ghana survey design What has been done thus far by the IFPRI’s M&E

team Challenges faced Detailed (question-by-question) discussion of

draft survey tool proposed for Ghana baseline survey

Introduction

Generate valuable information to inform AR research activities

Baseline indicators to gauge progress Impact assessment (with follow-up data)

What has been done?

D. Search for a local M&E coordinator and a partner to help collect baseline data

Innovations for Poverty Action (IPA) ISSER Interviews with applicants for the M&E position

(ongoing)

What has been done?

Time – fielding in March, 2013 Statistical power of AR research design

Increasing target communities vs. increasing sample farmers per community

Number and intensity of interventions Potential spillover

Getting the right M&E coordinator

… need to move forward fast (and carefully)!12
