The impacts of tourism on two communities adjacent to the Kruger National Park, South Africa
No full textThis paper explores the socioeconomic impacts of tourism associated with the Kruger National Park, South Africa's flagship national park, on the neighbouring villages of Cork and Belfast. Case study research, where the study area was characterised as a social-ecological system, was used to investigate the impacts of Park tourism on these communities. The findings offer a micro-scale, local community perspective of these impacts and indicate that the enclave nature of Park tourism keeps local communities separate from the Park and makes it hard for them to benefit from it. The paper concludes with reflections on this perceived separation, and suggests the need to make the Park boundaries more 'permeable' so as to improve relationships with adjacent communities, while also pragmatically managing community expectation

The role of acid in the formation of hydrogen-bonded networks featuring 4,4'-dicarboxy-2,2'-bipyridine (H2dcbp): Synthesis, structural and magnetic characterisation of {[Cu(H2dcbp)Cl2].H2O}2 and [Cu(H2dcbp)(NO3)2(H2O)]
No full textReported herein are the synthesis, structural and magnetic characterisation of two hydrogen-bonded networks featuring the 4,4?-dicarboxy-2,2?-bipyridine (H2dcbp) ligand: {[Cu(H2dcbp)(Cl)2]·H2O}2 1 and [Cu(H2dcbp)(NO3)2(H2O)] 2. Compounds 1 and 2 result from the reaction of CuCl2 and Cu(NO3)2, respectively, with H2dcbp under hydrothermal conditions in the presence of either HCl or HNO3. The acid ensures that H2dcbp remains protonated and provides the anions required for charge balance irrespective of Cu(II) precursor. Within 1 and 2 the H2dcbp ligand performs a dual role of Cu(II) coordination, via the 2,2?-bipyridine moiety, and propagates the formation of chains through hydrogen-bonding involving the peripheral 4,4?-dicarboxylic acid functionalities. Additional hydrogen bonding between the 4,4?-dicarboxylic acid groups, metal bound chloride and nitrate anions, in 1 and 2 respectively, and water molecules generate 3D networks. Variable temperature magnetic susceptibility measurements reveal very weak antiferromagnetic coupling between the Cu(II) centres across the chloride bridges in 1 (J = ?3.02 cm?1)
The EU Emissions Trading Directive: Opportunities and Potential Pitfalls
No full textThe European Union is on the verge of establishing an emissions trading program ten times the size of the Acid Rain trading program in the United States. Its design takes advantage of many lessons from existing experience with trading programs, as well as economic theory, and innovates in important ways. While we view this as an impressive development, concerns about equity, enforcement, and efficiency remain. Specifically, a lack of data and weaker environmental institutions in some EU Member States raises questions about both allowance allocations and compliance and enforcement. Although much attention has focused on whether prices will be “too low” in the first phase of the program, a greater risk is that uncertainty about program elements, technology and behavioral response, and external events could create volatile markets and costly compliance in the second phase. Regardless of outcome, the EU trading system will be influential in future international efforts to reduce greenhouse gases.European Union, climate change, emissions trading

From SO2 to Greenhouse Gases: Trends and Events Shaping Future Emissions Trading Programs in the United States
No full textCap-and-trade programs have become widely accepted for the control of conventional air pollution in the United States. However, there is still no political consensus to use these programs to address greenhouse gases. Meanwhile, in the wake of the success of the U.S. SO2 and NOx trading programs, private companies, state governments, and the European Union are developing new trading programs or other initiatives that may set precedents for a future national U.S. greenhouse gas trading scheme. This paper summarizes the literature on the “lessons learned” from the SO2 trading program for greenhouse gas trading, including lessons about the potential differences in design that may be necessary because of the different sources, science, mitigation options, and economics inherent in greenhouse gases. The paper discusses how the programs and initiatives mentioned above have been shaped by lessons from past trading programs and whether they are making changes to the SO2 model to address greenhouse gases. Finally, the paper concludes with an assessment of the implications of these initiatives for a future U.S. national greenhouse gas trading program.climate change, emissions trading, European Union, U.S. states, corporate environmentalism
Are giraffes pollinators or flower predators of Acacia nigrescens in Kruger National Park, South Africa?
No full textWe examined the relationship between giraffes (Giraffa camelopardalis) and Acacia nigrescens in Kruger National Park, South Africa, to determine whether these tall ungulates may be providing a pollination service for the trees, or are simply flower predators. We quantified florivory and subsequent fruit set in the presence and absence of giraffes. Acacia nigrescens flowers are clearly a substantial dietary component for giraffes. Although A. nigrescens flowers contain almost three times as much condensed tannin as leaves, giraffes consume large quantities of flowers (∼85% of flowers within reach), resulting in distinct browse lines on the trees. This substantial florivory is detrimental to the overall fecundity of A. nigrescens, with significantly reduced fruit set at heights on trees that are accessible to giraffes. Fruit set increased above the reach of giraffes, suggesting successful pollination by insects. Giraffes were effectively flower predators of A. nigrescens in the season we examined
