Acquired immunodeficiency syndrome (AIDS)	is a term which applies to the most advanced stages of HIV infection. It is defined by the occurrence of any of more than 20 opportunistic infections or HIV-related cancers.
barangay	is the basic political unit mandated under Section 38 of the Local Government Code of 1991 (RA 7160), “as the primary planning and implementing unit of government policies, plans, programs, projects and activities in the community and as a form wherein the collective views of the people may be expressed, crystallized and considered.”
Barangay Development Plan (BDP)	is a medium-term plan prepared by the barangay which contains the specific programs, projects and activities with corresponding project costs including the necessary fund flows to approximate the reasonable timing in the release of funds.
capacity	The combination of all the strengths, attributes and resources available within an organization, community or society to manage and reduce disaster risks and strengthen resilience.
children	refers to persons below eighteen (18) years of age or those over but are unable to fully take care of themselves or protect themselves from abuse, neglect, cruelty, exploitation or discrimination because of a physical or mental disability/condition. (RA 7610)
climate	Climate is the statistics of weather over long periods of time. It is measured by assessing the patterns of variation in temperature, humidity, atmospheric pressure, wind, precipitation, atmospheric particle count and other meteorological variables in a given region over long periods of time.
climate change	a change in global or regional climate patterns, in particular, a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
climate change adaptation	Climate change adaptation is a response to global warming, that seeks to reduce the vulnerability of social and biological systems to relatively sudden change and thus offset the effects of global warming.
Climate Change Mitigation	consists of actions to limit the magnitude or rate of long-term climate change. Climate change mitigation generally involves reductions in human emissions of greenhouse gases.
community development	a process where community members come together to take collective action and generate solutions to common problems.
disaster	A serious disruption of the functioning of a community or a society at any scale due to hazardous events interacting with conditions of exposure, vulnerability and capacity, leading to one or more of the following: human, material, economic and environmental losses and impacts.
disaster mitigation
disaster risk	The potential loss of life, injury, or destroyed or damaged assets which could occur to a system, society or a community in a specific period of time, determined probabilistically as a function of hazard, exposure, vulnerability and capacity.
Disaster Risk Reduction	is aimed at preventing new and reducing existing disaster risk and managing residual risk, all of which contribute to strengthening resilience and therefore to the achievement of sustainable development.
early warning systems	An integrated system of hazard monitoring, forecasting and prediction, disaster risk assessment, communication and preparedness activities systems and processes that enable individuals, communities, governments, businesses and others to take timely action to reduce disaster risks in advance of hazardous events.
earthquake	a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth’s crust or volcanic action.
earthquake intensity	is a number (written as a Roman numeral) describing the severity of an earthquake in terms of its effects on the earth’s surface and on humans and their structures.
earthquake magnitude	is a number that characterizes the relative size of an earthquake. Magnitude is based on measurement of the maximum motion recorded by a seismograph.
exposure	The situation of people, infrastructure, housing, production capacities and other tangible human assets located in hazard-prone areas.
flood	an overflowing of a large amount of water beyond its normal confines, especially over what is normally dry land.
Focus Group Discussions (FGD)
Geographic Information System (GIS)	is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data.
Global Positioning System (GPS)	A system of satellites, computers, and receivers that is able to determine the latitude and longitude of a receiver on Earth by calculating the time difference for signals from different satellites to reach the receiver.
global warming	a gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.
hazard	A process, phenomenon or human activity that may cause loss of life, injury or other health impacts, property damage, social and economic disruption or environmental degradation.
HIV
infant	A child who is under one year of age (PSA)
landslides	is defined as the movement of a mass of rock, debris, or earth down a slope. Landslides are a type of “mass wasting,” which denotes any down-slope movement of soil and rock under the direct influence of gravity.

Province
purok	also known as zone, is a political subdivision of a barangay. It is the smallest unit of governance in the Philippines led by a barangay councilor appointed to lead the purok.
Region
residential land use
resilience	The ability of a system, community or society exposed to hazards to resist, absorb, accommodate, adapt to, transform and recover from the effects of a hazard in a timely and efficient manner, including through the preservation and restoration of its essential basic structures and functions through risk management.

seasonal calendar

sitio	is a territorial enclave that forms part of a barangay. Typically rural, a sitio’s location is usually far from the center of the barangay itself and could be its own barangay if its population were high enough.
soil liquefaction	occurs when a saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress such as shaking during an earthquake or other sudden change in stress condition, in which material that is ordinarily a solid behaves like a liquid.
stakeholders
storm surge	A storm surge, storm flood or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, the severity of which is affected by the shallowness and orientation of the water body relative to storm path, as well as the timing of tides.
tsunami	are giant waves caused by earthquakes or volcanic eruptions under the sea.
typhoon	a violent wind that has a circular movement, found in the West Pacific Ocean
venn diagram
vulnerability	The conditions determined by physical, social, economic and environmental factors or processes which increase the susceptibility of an individual, a community, assets or systems to the impacts of hazards.
weather	the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc.
