Gender Intensification Hypothesis

AB - In 1990, Andrew Bakun proposed that increasing greenhouse gas concentrations would force intensification of upwelling-favorable winds in eastern boundary current systems that contribute substantial services to society. Because there is considerable disagreement about whether contemporary wind trends support Bakun's hypothesis, we performed a meta-analysis of the literature on upwelling-favorable wind intensification. The preponderance of published analyses suggests that winds have intensified in the California, Benguela, and Humboldt upwelling systems and weakened in the Iberian system over time scales ranging up to 60 years; wind change is equivocal in the Canary system. Stronger intensification signals are observed at higher latitudes, consistent with the warming pattern associated with climate change. Overall, reported changes in coastal winds, although subtle and spatially variable, support Bakun's hypothesis of upwelling intensification in eastern boundary current systems.

The Boserup-Ruthenberg framework has long been used to explain and understand the determinants of agricultural growth, the nature of the intensification of farming systems, investment, and technology adoption. The literature has produced an extensive body of evidence that summarizes or tests the hypothesis in Africa and often found it confirmed. However, in the past two decades, rapid population growth has put African farming systems under stress. At the same time, there has been a sharp increase in urbanization and economic growth that is providing new market opportunities for farmers. It is therefore necessary to investigate whether this has resulted in rapid intensification of farming systems, permitting rapid agricultural growth and maintenance or increase in the incomes of the farming population. This paper describes the status of intensification in six African countries using the first round of data from the Living Standards Measurement Study-Integrated Surveys on Agriculture. In addition, the paper (i) develops internationally comparable measures of overall agro-ecological crop potential and urban gravity in the farmers' location and (ii) estimates the causal impact of agro-ecological potential and urban gravity on population density, infrastructure, and market access and on a range of agricultural intensification variables. The paper shows that the new measures have relevant explanatory power. The descriptive analysis shows that the patterns of intensification observed across countries suggest several inconsistencies with Boserup-Ruthenberg. The paper also finds that urban gravity, except for its impact on crop intensities, has little impact on other intensification indicators.

Intensification trends in the low-density area, an expected extension of the cultivated area, in accordance with the demographic trend, was not detected on the aerial photographs taken from 1950 to 1969. This stability may be explained by one of two hypotheses:

The gender-intensification hypothesis states that psychological and behavioral differences between boys and girls become greater during early adolescence because of increased pressures to conform to traditional masucline and feminine gender roles (Galambos, 2004; Hill & Lynch, 1983).

The goal of the Tropical Cyclone Intensity (TCI) initiative is to improve the prediction of tropical cyclone (TC) intensity and structure change. The specific focus is an improved understanding of TC upper-level outflow layer processes and dynamics. This will be investigated in a comprehensive manner using the observations obtained during the TCI field phase in 2015 and high-resolution tropical cyclone models. Our ultimate goal is to improve the prediction of tropical cyclone intensity change, especially rapid intensification (RI) and rapid decay (RD) as well as TC structural changes that are hypothesized to occur through synergistic interactions with outflow.

A comparison between the two areas, whose present densities differ by a factor of 4, provides an opportunity to test the hypothesis that population density is a predictor of agricultural intensification. Such an investigation is, however, complicated by ecological and historical differences—no two areas can be strictly comparable. The high-and low-density areas represent different points on the rainfall gradient, have different soils and topography, and are differently located with respect to precolonial political and commercial centers.
