Farming systems analysis and modelling in the Livestock Systems and Environment group of ILRI

Download to read offline

Poster prepared by Mark van Wijk, Sabine Douxchamps, Randall Ritzema and Romain Frelat for the ILRI@40 Workshop, Addis Ababa, 7 November 2014

We deal with questions like: Can we identify robust interventions that cut across systems and socio-economic scenarios? Can we upscale strategies to quantify investment needs in interventions?

Farming systems analysis and modelling in the Livestock Systems and Environment group of ILRI

  1. 1. For detailed assessment of climate change and intensifica3on op3ons more detailed analyses at farm household level are performed. Here examples of a maize yield risk analysis (in kg/ ha; le@) and a trade off analysis in the use of crop residues (5 alloca3on strategies at 3 levels of manure use efficiency for a system in central Zimbabwe.

Current analyses focus on the quan3fica3on of (components of) food security across a wide range of systems in the developing world We have developed an extensive toolkit: -­‐ Comprehensive and mini surveys to collect panel data -­‐ A range of household models -­‐ A data base of household panel data (SSA, CA and SEA -­‐ Standardized tools for food security analyses Some key recent references S.

Here an example of analysis results we have now for more than 12k households across SSA In a wide range of systems livelihood typologies have been developed and key indicators for these types have been quan3fied. Above an example from West Africa, with market orienta3on and food security as key indicators for the 4 types. These four types are then related to adop3on rates of climate smart prac3ces. In collabora3on with partners at Wageningen U., Lund U., CSIRO, IITA, ICRAF, CIMMYT and others we have built a database of more than 25k farm household level panel data (the sites analysed (12k) are shown here) We assess the poten3al of different interven3ons to make a difference in the livelihoods of smallholder farmers. Here an example of the limited effects of even a 50% yield increase on the livelihoods of the poorest farmers (le@; FS (food security) ra3o group between 0 and 0.5), showing that for them transforma3onal change is needed (right, a scenario with an opportunity for a yearly $200 off farm income) This document is licensed for use under a Crea3ve Commons AVribu3on – Non commercial-­‐Share Alike 3.0 Unported License November 2014 We deal with ques3ons like: -­‐ Can we iden3fy robust interven3ons that cut across systems and socio-­‐ economic scenarios? -­‐ Can we upscale strategies to quan3fy investment needs in interven3ons?
