Sub Saharan farming systems are poorly resourced, highly diverse and aground by poverty traps making them rather impervious to change. As a consequence interventions usually result in benefits but also trade-offs and constraints to adoption.

Here we propose that R4D investments require careful ex-ante evaluation so that trade-offs are managed and likelihood of adoption increased. In this study we combined results from a large household survey across Eastern and Western Kenya (n=613), and developed a whole
farm simulation model (APSFarm-LivSim) to quantify the benefits and trade-offs from alternative Use of crop residues in Kenya. This work adds value to a wealth of publications on the topic, while its originality resides in the fact that we have moved from the conventional modelling of single case study farms, to simulate all the households surveyed across two contrasting agro-ecologies in Western and Eastern Kenya. Results show that benefits and trade-offs from “mulching or munching” differed across agro-ecologies and within agroecologies
across household typologies. Our analysis clearly shows the magnitude of the diversity of responses and trade-offs present, and supports the argument for the need of more integrative systems analyses that provide situation-specific information on practices and interventions that best fit the array of biophysical, socio-economic and market constraints.


About the Speaker:

Associate Professor Daniel Rodriguez is internationally recognised for his work on the design of more productive and resilient farming systems in Australia, and small-holder farms in the developing world. He has a background in crop eco-physiology and systems modelling.

Dr Rodriguez presently leads large projects on the sustainable intensification of agriculture in Australia and Africa and is Chief-Editor of Agricultural Systems.
