Hazard analysis and critical control points, or HACCP (/ ˈ h æ s ʌ p / [1]), is a systematic preventive approach to food safety from biological, chemical, and physical hazards in production processes that can cause the finished product to be unsafe and designs measures to reduce these risks to a safe level.
Energy security has been defined as "access to clean, reliable and affordable energy services for cooking and heating, lighting, communications and productive uses" (United Nations), [13] and as "uninterrupted physical availability [of energy] at a price which is affordable, while respecting environment concerns". Food security is defined by ...
Based on literature of the last 40 years, 5 + 1 stages in the evolution of food safety risk communication can be identified: [7] Pre-risk communication era, Deficit model, Dialogue model, Partnership model, and Behavioural insight model. Expected future trends are summarised as a 6th stage, called Controlled risk environment model.
In hazard identification, sources of data on the risks associated with prospective hazards are identified. For instance, if a site is known to be contaminated with a variety of industrial pollutants , hazard identification will determine which of these chemicals could result in adverse human health effects, and what effects they could cause.
The Millennium Project assessed definitions of environmental security and created a synthesis definition: Environmental security is environmental viability for life support, with three sub-elements: preventing or repairing military damage to the environment, preventing or responding to environmentally caused conflicts, and
When evaluating environmental impact, experts use two types of indicators: "means-based", which is based on the farmer's production methods, and "effect-based", which is the impact that farming methods have on the farming system or on emissions to the environment. An example of a means-based indicator would be the quality of groundwater, which ...
Food vs fuel is the debate regarding the risk of diverting farmland or crops for biofuels production in detriment of the food supply on a global scale. Essentially the debate refers to the possibility that by farmers increasing their production of these crops, often through government subsidy incentives, their time and land is shifted away from other types of non-biofuel crops driving up the ...
