Firewood fetching activity requires 9.67% of total human energy expenditure per year.
Furthermore, Haisman and Goldman [70] stated that the human energy expenditure while walking on difficult terrains and thick bushes may overwhelm human physiological limits in comparison to walking on the smooth surfaces.
The Lejeune et al. [69] study shows that walking on loose-soil surfaces such as sand requires 2.1 2.7 times more human energy expenditure than walking on solid ground at the same speed.
To modeling the human energy expenditure amount, the participants were asked to virtually walk from their origin to the destination so as to earn the highest number of points possible.
Increasing human energy expenditure through hBAT by cold-exposure (Cypess et al., 2009; Aherne and Hull, 1966) and exercise (Lee et al., 2013; Hondares et al., 2014) however, would require drastic changes in life style.
The mean values for human energy expenditure were 10·02, 12·11 and 13·15 kJ min−1 during rotatilling, 11·69, 14·62 and 17·96 kJ min−1 during rotapuddling and 11·28, 13·15 and 15·66 kJ min−1 during walking alone on puddled field at the forward speeds of 0·30, 0·47 and 0·63 m s−1, respectively.
Therefore BAT might contribute substantially to human energy expenditure.
Human resource expenditure included basic salaries, allowances, bonuses, social insurance, housing accumulation funds, purchasing subsidies, living subsidies, and medical expenses.
Not surprising, the empirical evidence on the impact of remittances on human capital expenditures is mixed.
