    Abstract:

    As the most important factor in the world, palm oil is a crucial element that contributed to economic growth of a country. Besides as a role of the important vegetables oil, palm oil also gives a negative effect on environment through expanding the palm oil plantation. Therefore, this study aims to investigate the effect of global crude palm oil (CPO) price, marketing margins, and palm oil plantations on Environmental Destruction in the short-term and long-term. For examining the short-term and long-term effect, this study used Johansen Cointegration approach involving the bivariate causality with the Pirwise Granger Causality test and multivariate causality relationships with the Wald test. Also, we analyzed the responds of independent variables to dependent variable using impulse response (IRF) and variance decomposition (VD). This study used a monthly secondary data starting on 2008 to 2017 i.e. Environmental Quality Index, Global CPO price, Marketing margins and palm oil plantations. The data collected from 5 sources i.e. Central Bureau of Statistic (BPS), Food and Agriculture Organization (FAO), World Trade Organization, Central Bank of Indonesia (BI) and the Central Bank of Malaysia (BNM). The results of analysis shows that there is long-term relationship of global CPO price, marketing margins, and palm oil plantations on Environmental quality index. For short run, this study found that global CPO price has a significant positive effect on Environmental quality index. Meanwhile, the size of palm oil plantation and marketing margins have a significant negative effect on Environmental quality index in Indonesia. Also, using the bivariate test, this study proves that there is one way causality relationship between the global CPO prices, marketing margins and size of oil palm area on Environmental quality index. In addition, the global CPO prices and marketing margins fluctuations causing shock in Environmental quality index.

  • Successful small-scale irrigation or Environmental Destruction? The political ecology of competing claims on water in the Uluguru Mountains, Tanzania
    Journal of Political Ecology, 2017
    Co-Authors: Elizabeth Harrison, Anna Mdee
    Abstract:

    In the Uluguru Mountains of Tanzania, an expansion in informal hosepipe irrigation by small-scale farmers has enabled the development of horticulture and resulted in improvements in farmers’ livelihoods. This has taken place largely independently of external support and can be seen as an example of the ‘private’ irrigation that is increasingly viewed as important for sub-Saharan Africa. However, these activities are seen by both representatives of government and some donors, as the cause of both Environmental degradation and water shortages downstream, especially in the nearby city of Morogoro. As a result, there have been attempts to evict the farmers from the mountain. Negative narratives persist and the farmers on the mountainside are portrayed as a problem to be ‘solved’. This article explores these tensions, contributing to debates about the formalisation of water management arrangements and the place of the state in regulating and adjudicating rights to access water. We argue that a focus on legality and formalisation serves to obscure the political nature of competing claims on resources that the case illustrates.

  • the impact of human induced Environmental Destruction on destination image perception and travel behaviour the case of australia s great barrier reef
    Journal of Vacation Marketing, 2017
    Co-Authors: Javier Salvatierra, Gabrielle Walters
    Abstract:

    The study presented in this article provides a valuable insight into the impact of human-induced Environmental Destruction on the travel market’s image perceptions of a World Heritage-listed tourism icon: the Great Barrier Reef (GBR). The study employs a pre-/post-experimental design to explore how tourists are likely to respond to the media hype surrounding the construction of a port terminal, known as the Abbot Point Project, which will inevitably have some perceived Environmental consequence for the ecological sustainability of a section of the GBR. We measured the change in respondents’ image perceptions and travel intentions as a result of their exposure to information about the Abbott Point Project and explored how existing knowledge, past experience and demographic background may influence this change. The findings reveal a significant change in tourists’ perceptions concerning Australia’s conservation efforts towards the GBR, and consequently a change is noted in terms of the time frame in which tourists intend to visit the icon. The results of this study provide valuable information for destination managers responsible for marketing the GBR and other destinations subject to human-induced, and often controversial, Environmental Destruction.
