While there is a large body of literature on the negative health effects of air pollution, there is much less written about its effects on cognitive performance for the whole population. This paper studies the effects of contemporaneous and cumulative exposure to air pollution on cognitive performance based on a nationally representative survey in China. By merging a longitudinal sample at the individual level with local air-quality data according to the exact dates and counties of interviews, we find that contemporaneous and cumulative exposure to air pollution impedes both verbal and math scores of survey subjects. Interestingly, the negative effect is stronger for men than for women. Specifically, the gender difference is more salient among the old and less educated in both verbal and math tests.

After decades of near silence on the matter, sex is being talked about in China. But what is being said? Who is allowed to speak? And whose purposes are being served? This ground-breaking book takes a critical look at how sex in China is thought and talked about. Drawing on the work of the country’s foremost sex experts, and years of research in the field, it gives an overview of the sexual landscape in China today. Including new material on transsexuals, fetishism, sex aids and pornography, the book shows that the dominant ways of thinking about sex are neither innocent nor inconsequential, and that amid catalogues of prescriptions linking self-management to the collective good, people are making decisions about how to live their sexual lives. The most lively and accessible critique of sexual discourse, this book will be essential reading for scholars in Chinese studies, cultural studies and sexuality and gender studies.

The focus in this paper is on two relatively large maize-based contract farming (CF) schemes with fixed input packages (Masara and Akate) and a number of smaller and more flexible CF schemes in a remote region in Ghana (Upper West). Results show that these schemes led to improved technology adoption and yield increases. In addition, a subset of maize farmers with high yield improvements due to CF participation had high gross margins. However, on average, yields were not high enough to compensate for higher input requirements and cost of capital. On average, households harvest 29–30 bags (100 kg each), or 2.9–3.0 metric tons, of maize per hectare, and the required repayment for fertilizer, seed, herbicide, and materials provided under the average CF scheme is 21–25 bags (50 kg each) per acre, or 2.6–3.0 tons per hectare, which leaves almost none for home consumption or for sale. Despite higher yields, the costs to produce 1 ton of maize under CF schemes remain high on average—higher than on maize farms without CF schemes, more than twice that of several countries in Africa, and more than seven times higher than that of major maize-exporting countries (the United States, Brazil, and Argentina). Sustainability of these CF schemes will depend on, from the firms’ perspective, minimizing the costs to run and monitor them, and from the farmers’ perspective, developing and promoting much-improved varieties and technologies that may lead to a jump in yields and gross margins to compensate for the high cost of credit.

At a time when donors and governments are increasing efforts to mainstream gender in agriculture, it is critical to revisit long-standing wisdom about gender inequalities in agriculture to be able to more efficiently design and evaluate policy interventions. Many stylized facts about women in agriculture have been repeated for decades. Did nothing really change? Is some of this conventional wisdom simply maintained over time, or has it always been inaccurate? We use longitudinal data from Ghana to assess some of the facts and to evaluate whether gender patterns have changed over time. We focus on five main themes: land, cropping patterns, market participation, agricultural inputs, and employment. We add to the literature by showing new facts and evidence from more than 20 years. Results are varied and highlight the difficulty of making general statements about gender in agriculture.

This paper assesses whether fertilizer subsidy programs can be better targeted to resource-poor farmers using the case of Ghana and proxy means test approaches. Past fertilizer subsidy programs in the country have not been particularly targeted to the poor, even as targeting poor and smallholder farmers has become key in the program implementation guidelines. As a result, many poor farmers have not benefited from past programs. Our results show that targeting approaches based on proxy means tests that use the correlates of poverty to select beneficiary farmers can potentially improve the poverty outreach and costeffectiveness of Ghana’s fertilizer subsidy programs. Therefore, we propose that the proxy means test approach should be considered for implementing Ghana’s fertilizer subsidy programs, first in a pilot project involving a few communities, and later, if found successful, in a full-scale program.
