Costa Rica

Summary: 

Costa Rica is a small country in Central America of about 4.5.million people. It is located in the tropical area and has a hot climate, but cooler along the coasts and in the mountains up to 2000m altitude. Or (up to 2000m high)? Climate change will bring more hot days, changing rain patterns and possibly more violent weather events. The specific projections for this country are shown here. Costa Rica is part of V20, the Climate Vulnerable Forum.

Current and Future Heat Stress in Nicaraguan Work Places under a Changing Climate

Publication Date: 
2013

While climate change continues to increase ambient temperatures, the resulting heat stress exposure to workers in non-climate controlled settings is not well characterized, particularly in low and middle income countries. This preliminary report describes current heat stress in Nica-raguan work places and estimates occupational heat stress in 2050. From over 400 measurements of heat exposure using wet bulb globe temperature, more than 10% of all measurements exceeded the safety threshold for the combination of light work and rest at the ratio of 25:75.

A feature of climate impacts on occupational health and safety are physiological limits to carrying out physical work at high heat exposure. Heat stress reduces a workers work capacity, leading to lower hourly labour productivity and economic output. We used existing weather sta-tion data and climate modeling grid cell data to describe heat conditions (calculated as Wet Bulb Globe Temperature, WBGT) in South-East Asia.

The WBGT heat stress index has been well tested under a variety of climatic conditions and quantitative links have been established between WBGT and the work-rest cycles needed to prevent heat stress effects at the workplace. While there are more specific methods based on indi-vidual physiological measurements to determine heat strain in an individual worker, the WBGT index is used in international and national standards to specify workplace heat stress risks.

The 'Hothaps' programme for assessing climate change impacts on occupational health and productivity: an invitation to carry out field studies

Publication Date: 
2009

The ‘high occupational temperature health and productivity suppression’ programme (Hothaps) is a multicentre health research and prevention programme aimed at quantifying the extent to which working people are affected by, or adapt to, heat exposure while working, and how global heating during climate change may increase such effects. The programme will produce essential new evidence for local, national and global assessment of negative impacts of climate change that have largely been overlooked.

Workplace heat stress, health and productivity – an increasing challenge for low and middle income countries during climate change.

Publication Date: 
2009

Background: Global climate change is already increasing the average temperature and direct heat exposure in many places around the world. Objectives: To assess the potential impact on occupational health and work capacity for people exposed at work to increasing heat due to climate change. Design: A brief review of basic thermal physiology mechanisms, occupational heat exposure guidelines and heat exposure changes in selected cities.

Regional maps of occupational heat exposure: past, present and potential future

Publication Authors: 
Publication Date: 
2010

Background: An important feature of climate change is increasing human heat exposure in workplaces without cooling systems in tropical and subtropical countries. Detailed gridded heat exposure maps will provide essential information for public health authorities. Objectives: To develop and test methods for calculating occupational heat exposures and present results in easily interpreted maps.
