Initiative used in a variety of disaster and emergency contexts. Is based on the provision of cash, paid in the local currency, in exchange for work completed on public works projects.

A check drawn by a bank on its own funds and signed by the cashier. Performance securities are often required in this form.

In water wells it is a steel or PVC pipe that is installed in the borehole to keep the borehole from collapsing and to protect drilled aquifers from contamination.

Casual workers are workers who have an explicit or implicit contract of employment, which is not expected to continue for more than a short period and whose duration is to be determined by national circumstances. These workers may be classified as being employees or own-account workers according to the specific characteristics of the employment contract.

A person killed or injured as a result of an accident, excluding attempted suicide.

Computer tomography scanners (CT or CAT scanner) is an x-ray machine which combines many x-ray images with the aid of a computer to generate cross-sectional views and, if needed, three-dimensional images of the internal organs and structures of the body.

Ship consisting of two hulls connected with a deck

The volume changes recorded as catastrophic losses in the other changes in the volume of assets account are the result of large scale, discrete and recognizable events that may destroy a significantly large number of assets within any of the asset categories.

It collects data according to the operational characteristics of each fishing method and in sufficient detail to facilitate effective stock assessment and assess impacts on VMEs. Such data should include catch by species (both target and non-target, retained and discarded), gear and vessel type, effort statistics appropriate to each fishing method, fishing location, depth of fishing, fishing date and time.

A document accompanying an exported consignment that is validated by a competent authority and includes relevant information concerning catch and trade of the product covered by the catch certificate.; An official document accompanying a consignment and validated by the competent authority, allowing accurate and verifiable information concerning fish passing through the supply chain.

Catch reports for regulated resources must include the quantities held on board when a Community fishing vessel enters the Regulatory Area, weekly catches, the quantities held on board when it leaves the Regulatory Area and the quantities loaded and unloaded for each transshipment of fish during the vessel's stay in the Regulatory Area. Each Member State is required to forward catch reports to the NEAFC Secretariat.

A system that tracks and traces fish from the point of capture through unloading and throughout the supply chain. A CDS records and certifies information that identifies the origin of fish caught and ensures they were harvested in a manner consistent with relevant national, regional and international conservation and management measures.; A system with the primary purpose of helping determine throughout the supply chain whether fish originate from catches taken consistent with applicable national, regional and international conservation and management measures, established in accordance with relevant international obligations.

The amount of catch that is taken per unit of fishing gear, e.g. number of fish per longline hook-months is one way to express CPUE.

Comparing observed catch compositions against unobserved reported catch compositions as a mechanism to detect likely discarding.

The fraction of a fish stock which is caught by a defined unit of the fishing effort. When the unit is small enough that it catches only a small part of the stock -- 0.01 or less -- it can be used as an instantaneous rate in computing population change. Also called: catchability coefficient, *force of fishing mortality.
