How are Organic Farming Inputs Evaluated?

The origin and hazard of inputs to crop protection in organic farming systems: are they sustainable?$

Sustainability is de®ned as the ability of a system to `continue'. In view of this de®nition, several aspects of the crop protection activity in organic farming are reviewed according to their ability to `continue'. As no absolute measure of sustainability is available, this analysis takes the form of a comparison between organic and conventional crop protection methods. Two elements of crop pr...

On Maximum Weight Clique Algorithms, and How They Are Evaluated

Maximum weight clique and maximum weight independent set solvers are often benchmarked using maximum clique problem instances, with weights allocated to vertices by taking the vertex number mod 200 plus 1. For constraint programming approaches, this rule has clear implications, favouring weight-based rather than degree-based heuristics. We show that similar implications hold for dedicated algor...

Acknowledgement We at the NAVDANYA wish to acknowledge the farmers contributions who for centuries have grown and conserved diversity in their fields. In particular, we want to thank all those farmers who, through their participation in our conservation efforts are in effect co-authors of this work and are changing India's farm destiny to one of hope and health. Publication of this volume has b...
