National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

How Tariffs Shape Trade‐Embodied Emissions in the European Union: Sectoral Heterogeneity in Final Demand

Sustainable Development, EarlyView.
ABSTRACT This paper examines the environmental implications of tariffs on greenhouse gas emissions embodied in extra‐European Union imports consumed by domestic final demand in the EU. Using a multidimensional country‐sector‐year framework, the study investigates whether tariff changes are associated with variations in trade‐embodied emissions and ...

Facing Truths About Population Management

Zoo Biology, EarlyView.
Populations of wildlife, and domestic animals have large sinks for surplus animals. By contrast, zoos don't. Humans in industrialized societies are socialized with companion animals, i.e. surplus (i.e., typically denied reproduction) originating from unseen breeding cores.

Economic Analysis of Infrastructure Investment and Break‐Even Carbon Prices for Low‐Water, Low‐Emission Farming Techniques in Vietnam

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Excessive water use in rice production is a major source of methane emissions, the dominant greenhouse gas from Vietnam's agricultural sector. Improving water‐use efficiency can enhance water security and reduce emissions, but achieving these gains requires substantial changes in farming practices and significant investment in supporting ...

Forces Behind South Australia's Unusual Structural Changes Since 1840

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT The agricultural sector's share of GDP in growing economies typically declines but, for a century from the early 1850s, Australia's did not. That trend is most evident for the former colony and now State of South Australia (SA). Moreover, that share for SA has been almost flat since 1980 as well, along with the agricultural sector's share of ...
