Science and technology have played a vital role in keeping agricultural production a step ahead of rapid global population growth during the past four decades. However, Green Revolution technologies did not benefit the vast rainfed and other marginal areas with high concentrations of hunger and poverty. The new farming technologies were also not friendly to the environment, often resulting in degradation of land, water and biodiversity.

This issue of the journal includes three papers that touch on relations among socioeconomic status (SES), health, and air quality. Jerrett et al considered whether SES differentials in Hamilton, Ontario, modify the temporal relations between daily mortality and either coefficient of haze (COH) or SO2. Martins et al did a similar analysis with respect to PM10 in Sao Paulo, Brazil. The third paper, by Gouveia et al, also involved Sao Paulo but examined cross sectional relations between several pollutants and infant birth weight.
Poor households in Bangladesh depend heavily on wood, dung and other biomass fuels for cooking. This paper provides a detailed analysis of the implications for indoor air pollution, drawing on new monitoring data for respirable airborne particulates (PM10) in a large number of Bangladeshi households.

This is partly due to a perception in the ARI professional community that little progress has been made in understanding this complicated set of issues.
