Targeting deforestation rates in climate change policy: a "Preservation Pathway" approach
We present a new methodological approach to incorporating deforestation within the international climate change negotiating regime. The approach, called "Preservation Pathway" combines the desire for forest preservation with the need to reduce emissions associated with forest loss by focusing on the relative rate of change of forest cover as the criteria by which countries gain access to trading preserved forest carbon stocks. This approach avoids the technically challenging task of quantifying historical or future deforestation emission baselines. Rather, it places emphasis on improving quantification of contemporary stocks and the relative decline in deforestation rates necessary to preserve those stocks. This approach places emphasis on the complete emissions trajectory necessary to attain an agreed-upon preserved forest and as such, meets both forest conservation and climate goals simultaneously
Phenotypic Plasticity of Leaf Shape along a Temperature Gradient in Acer rubrum
Both phenotypic plasticity and genetic determination can be important for understanding how plants respond to environmental change. However, little is known about the plastic response of leaf teeth and leaf dissection to temperature. This gap is critical because these leaf traits are commonly used to reconstruct paleoclimate from fossils, and such studies tacitly assume that traits measured from fossils reflect the environment at the time of their deposition, even during periods of rapid climate change. We measured leaf size and shape in Acer rubrum derived from four seed sources with a broad temperature range and grown for two years in two gardens with contrasting climates (Rhode Island and Florida). Leaves in the Rhode Island garden have more teeth and are more highly dissected than leaves in Florida from the same seed source. Plasticity in these variables accounts for at least 6–19 % of the total variance, while genetic differences among ecotypes probably account for at most 69–87 %. This study highlights the role of phenotypic plasticity in leaf-climate relationships. We suggest that variables related to tooth count and leaf dissection in A. rubrum can respond quickly to climate change, which increases confidence in paleoclimate methods that use these variables
Wealthy and healthy? New evidence on the relationship between wealth and HIV vulnerability in Tanzania
Using AIS/DHS data for Tanzania in 2003-4, 2007-8 and 2011-12 and borrowing from the methodology used in Parkhurst (2010) we analyse the changing relationship between wealth and HIV prevalence in Tanzania. Findings are tabulated, graphed and discussed.
We find the relationship is multifaceted and dynamic: women are disproportionately affected in all wealth quintiles and experience a stronger ‘wealth effect’; some groups experience an increase in prevalence even as population prevalence declines. Relative wealth and poverty are associated with increased prevalence, suggesting that structural drivers create a variety of risk situations – as well as protective factors – affecting different groups.
We also consider data on testing refusals: wealthier men were consistently more likely to decline testing. Continuing to unpack this complex and shifting relationship is necessary in order to fully understand the structural drivers of HIV transmission and access of testing services, enabling the formulation of appropriate policy responses
