“…The most common heat-related health outcome assessed was HRI (n = 57; 62%). Twenty-seven out of 57 of these studies relied on selfreported HRI symptoms (25,27,30,(40)(41)(42), while 21 measured various physiological parameters such as core body temperature, skin temperature, heart rate, blood pressure, changes in body weight, or urine specific gravity (61,68,(70)(71)(72)(73)(74)(75)(76)(77)(78)(79)(80)(81)(82)(83)(84)(85)(86)(87)(88). Another commonly assessed heat-related health outcome was kidney disease (n = 28; 30%).…”

“…Heat-related Illnesses (HRI) are the most common health effects experienced by agricultural workers as a result of their prolonged exposure to high temperatures (30,(40)(41)(42). HRI are a continuum of diseases, ranging from mild symptoms such as heavy sweating, dizziness, fatigue, vomiting, headaches, and muscle cramps to more severe conditions such as lifethreatening heat strokes (12).…”

Due to the continuous rise of global temperatures and heatwaves worldwide as a result of climate change, concerns for the health and safety of working populations have increased. Workers in the food production chain, particularly farmworkers, are especially vulnerable to heat stress due to the strenuous nature of their work, which is performed primarily outdoors under poor working conditions. At the cross-section of climate change and farmworkers' health, a scoping review was undertaken to summarize the existing knowledge regarding the health impacts associated with climate change and heat stress, guide future research toward better understanding current and future climate change risks, and inform policies to protect the health and safety of agricultural workers. A systematic search of 5 electronic databases and gray literature websites was conducted to identify relevant literature published up until December 2021. A total of 9045 records were retrieved from the searches, of which 92 articles were included in the final review. The majority of the reviewed articles focused on heat-related illnesses (n = 57) and kidney diseases (n = 28). The risk factors identified in the reviewed studies included gender, dehydration, heat strain, wearing inappropriate clothing, workload, piece-rate payment, job decision latitude, and hot environmental conditions. On the other hand, various protective and preventive factors were identified including drinking water, changing work hours and schedule of activities, wearing appropriate clothing, reducing soda consumption, taking breaks in shaded or air-conditioned areas, and increasing electrolyte consumption in addition to improving access to medical care. This review also identified various factors that are unique to vulnerable agricultural populations, including migrant and child farmworkers. Our findings call for an urgent need to expand future research on vulnerable agricultural communities including migrant workers so as to develop effective policies and interventions that can protect these communities from the effects of heat stress.

“…They also recognized that, even though there were adaptation strategies for coping with heat stress in Baku East in Northern Ghana, these strategies were ineffective. In their study of the impact of heat on health and productivity among maize farmers in the Gombe province of Nigeria, Sadiq, Hashim [65] found that farmers were frequently exposed to heat stress-a condition that was contributing to heat exhaustion and productivity decreases among small-holder producers.…”

Agricultural production in sub-Saharan Africa remains dependent on high inputs of human labor, a situation associated with direct exposure to daylight heat during critical periods of the agricultural calendar. We ask the question: how is the Wet-Bulb Globe Temperature (WBGT) going to be distributed in the future, and how will this affect the ability of smallholder farmers to perform agricultural activities? Data from general circulation models are used to estimate the distribution of WBGT in 2000, 2050 and 2100, and for high activity periods in the agricultural calendar. The distribution of WBGT is divided into recommended maximum WBGT exposure levels (°C) at different work intensities, and rest/work ratios for an average acclimatized worker wearing light clothing (ISO, 18). High WBGTs are observed during the two periods of the East African. In February to March, eastern and coastal regions of Kenya and Tanzania witness high WBGT values—some necessitating up to 75% rest/hour work intensities in 2050 and 2100. In August to September, eastern and northern Kenya and north and central Uganda are vulnerable to high WBGT values. Designing policies to address this key challenge is a critical element in adaptation methods to address the impact of climate change.

“…Due to intensified global warming in recent years, extreme summer heat events tend to be frequent across the country. When the WBGT temperature exceeds 30°C, work ability will be reduced and serious health problems, such as heat stroke, muscle cramps, and even death, may occur (Sadiq et al, 2019). Moderate or very hot conditions may cause a 3%-12% reduction in work time of indoor workers (Xia et al, 2018).…”

Examining the impact of long-term temperature rise on wages is not only beneficial for gaining insight into the economic consequences of climate change, but also of great reference value to reduce income disparity and alleviate relative poverty. Based on the panel data of 30 provincial capitals from 1996-2018, the Wet Bulb Globe Temperature (WBGT) is adopted in this paper to conduct an empirical analysis of temperature rises’ impact on wage in various industries. It is found that, firstly, temperature rise will significantly reduce the growth of wage and show heterogeneity. Among them, the growth of wage in the manufacturing industry is most prominently affected by rising annual average temperatures. Second, in terms of seasonal differences, the negative impact of temperature rise on wage growth is mainly in summer. Different temperature swings and different vulnerability producers demonstrate lead to largely dissimilar marginal impacts of temperature rise in different regions. Wages in relatively vulnerable regions and regions with relatively sharp temperature fluctuations are more significantly affected by the increase in average summer temperatures. Thirdly, in the long run, the negative impact of annual average temperature increases on the wages of agriculture industries shows a notable cumulative effect, which mainly comes from the irreversible impact of temperature increase on labor productivity, and will further widen the income gap between regions. Based on the above findings, this paper proposes targeted strategies from two dimensions, “mitigation” and “adaptation”, in order to narrow the regional income gap and achieve balanced development, and to provide theoretical references for subsequent policies responding to climate change.
