|Description=In the GISMO model, the impacts of global environmental change on human development are modelled by considering impacts on human health – either directly, for example, via the impact of climate change on malaria, or indirectly, such as by the impact of climate change on food availability. In addition to environmental factors, human health is also driven by socioeconomic factors, including income levels and educational attainment. To take account of these different factors and their interrelation, the GISMO model consists of three modules that address human health, poverty and education (Figure 7.6.1). The modules are linked through a cohort component population model, including endogenous fertility and mortality (for details see [[Hilderink, 2000]]). Fertility levels are modelled using a convergence level that is determined by female educational levels, and a speed of convergence, determined by the human development index (HDI) (see below). Mortality rates are determined by the health module, which is discussed in further detail in the remainder of this section. Future trends in migration, including urbanisation, are put exogenously into the model (for details see [[Hilderink, 2000]]) | |Description=In the GISMO model, the impacts of global environmental change on human development are modelled by considering impacts on human health – either directly, for example, via the impact of climate change on malaria, or indirectly, such as by the impact of climate change on food availability.

(ii) Access to food, water and energy. GISMO relates incidence and case fatality rates of major communicable (infectious) diseases to access to food, water and energy (see Table), with access defined by per-capita food availability, access to safe drinking water and improved sanitation, and access to modern energy sources for cooking and heating. The per-capita food availability (Kcal/cap/day) is obtained from the IMAGE model (Section 4.2). The levels of access to safe drinking water and improved sanitation are modelled separately by applying linear regression. The explanatory variables include GDP per capita, urbanisation rate and population density. Developments in water supply are assumed to be implemented ahead of sanitation. As such, developments in access follow a pathway from no sustainable access to safe drinking water and basic sanitation, to improved water supply only, improved water supply and sanitation, household connection for water supply only, and to a household connection for watersupply and sanitation. The level of access to modern energy sources for cooking and heating distinguishes between the use of 1) traditional biomass and coal on traditional stoves; 2) traditional biomass and coal on improved stoves; and 3) the use of modern energy carriers (electricity, natural gas, LPG, kerosene, modern biofuels and decentralised renewable sources). Trends in access to modern energy sources are taken from the TIMER residential model (Section 4.1.1). | (ii) Access to food, water and energy.

Child underweight and prevalence of undernourishment. For children under the age of five, undernourishment is expressed as underweight (measured as weight-for-age), whereas for older ages prevalence of undernourishment is used. The direct effect of undernourishment is protein deficiency, which for children mortality rates is scaled to their underweight status; for older age groups, mortality rates are scaled to levels of undernourishment. Indirectly, undernourishment increases the incidence of diarrhoea and pneumonia, and the case fatality of malaria, diarrhoea and pneumonia. These indirect effects are only modelled for children under the age of five. | Child underweight and prevalence of undernourishment.
