NAT.B08 Soil Health
About the data
Over 40% of living organisms in terrestrial ecosystems associate directly with soils during their life cycle, making soils among the most important reservoirs of biodiversity (UNEP, BRS Conventions and Minamata Convention, 2021). However, current unsustainable agricultural practices and other business activities have led to the degradation of around one-third of the world’s soil, resulting in significant negative impacts on biodiversity and soil health (TEEB, 2018). This indicator focuses on practices that reduce soil degradation and encourage regeneration in the system by improving soil health and agrobiodiversity.These include helping to tackle climate change, improving air and water quality and reducing the cost of accessing goods and services.
A note on the scoring system
Wikirate uses a standardized 10-point scoring system to enable comparison of company scores across different benchmarks. In the Nature Benchmark, companies can earn 1 point per indicator, which are then added together and calculated as a percentage of the total score for a measurement area (MA) to determine the final score for the MA. The overall Wikirate score is calculated by combining these scores with the appropriate weightings, and converting them to a 10-point scale. For instance, if a company achieves a final score of 50, the corresponding WikiRating will be 5.
Formula
score = (x) -> if x == "Yes" 10 else 0 redistributed_weights = (weights, values) -> num_of_weighted_values = weights.length for value, index in values if value == "Not Applicable" num_of_weighted_values -= 1 redistributed_weight_value = weights[index] for weight, i in weights if weight == 0 continue weights[i] = weight + redistributed_weight_value/num_of_weighted_values weights[index] = 0 weights weights = [0.2, 0.2, 0.2, 0.2, 0.2] soil_health = [increasing_agrobiodiversity_evidence, agrobiodiversity_evidence, soil_health_targers_reporting, agrobiodiversity_impact, agrobiodiversity_targets_reporting] redistributed_weights(weights, soil_health) weights.reduce((weighted_sum, weight, index) -> weighted_sum + weight*score(soil_health[index]) , 0)
