The traditional environmental Kuznets curve (EKC) hypothesis postulates that environmental degradation follows an inverted U-shaped relationship with gross domestic product (GDP) per capita. We tested the EKC hypothesis with bird populations in 5 different habitats as environmental quality indicators. Because birds are considered environmental goods, for them the EKC hypothesis ...

Concerns about sustainability in agricultural systems centre on the need to develop technologies and practices that do not have adverse effects on environmental goods and services, are accessible to and effective for farmers, and lead to improvements in food productivity. Despite great progress in agricultural productivity in the past half-century, ...

As a result of agricultural intensification, more food is produced today than needed to feed the entire world population and at prices that have never been so low. Yet despite this success and the impact of globalization and increasing world trade in agriculture, there remain large, persistent and, in some ...

90% of the world's rice is grown and consumed in Asia, with each hectare of rice-producing land providing food for 27 people. By 2050, because of population growth and increasing urbanisation, each remaining hectare will have to feed at least 43 people. This means that yields must be increased by ...

The transition from foraging to farming allowed humans to produce several foods in abundance that were previously scarce. However, early farmers had to adapt to benefit fully from this energy-rich but initially detrimental food supply. Perry et al. recently showed that natural selection has increased the copy number of a ...
Dornburg, V.
The increased use and potential growth of biomass for energy has triggered a heated debate on the sustainability of those developments as biomass production is now also associated with increased competition with food and feed production, loss of forest cover and the like. Besides such competition, also the net reduction ...

Vegetarian foodways are relatively universal – identifiable in different parts of the world and in different local contexts. However, owing to the particularities of these local contexts, vegetarian foodways are also culturally specific. I use the empirical example of vegetarianism in Japan on the one hand in order to both ...

Epizootics (nonhuman animal disease epidemics) can have detrimental impacts on livelihoods through a complex interaction of demographic trends, food production, and animal disease. Differences in the rate of demographic shifts, including rates of population growth, economic growth, urbanization, environmental sustainability, and role of women in society, are strong driving forces ...
