The Global Centre for Risk and Innovation (GCRI)
Topics at Food Nexus: the pages in this section are listed below, each with its own scope and status.
The Food Nexus topics are the eight subject dossiers of its field, among them agricultural production, food security and access, and soil and land. Each dossier sets out how the risk develops, what is measured and in which units, the public sources and their licences, the methods, who decides and the limits of the evidence.
GCRI is a research, development and policy institution. It is not a regulator, and it does not certify, license or approve; its findings carry their methods and uncertainty.
The topics follow the chain from production through storage, trade and markets to access. Soil and land and agritech sit at the production end; food, water and energy and food system shocks are where the chain is tested.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Crop yield | The quantity of a crop harvested per unit of harvested area, usually in tonnes per hectare. |
| Prevalence of undernourishment | The share of a population whose habitual food consumption is insufficient for the dietary energy needed for a normal, active and healthy life; SDG indicator 2.1.1. |
| Land degradation neutrality | A state in which the amount and quality of land resources stay stable or increase within a given time and area, the target of SDG 15.3 under the UNCCD. |
| Crop water productivity | The crop output obtained per unit of water consumed, measured from fields or estimated from satellites by FAO WaPOR. |
| Post-harvest loss | The measurable quantity and quality of food lost between harvest and consumption, from handling, storage, pests and spoilage. |
