| The dependency of small island economies on natural resources coupled with the pubic nature of these resources means that sustainability is a topical issue especially when development projects offer opportunities for "better living" for communities. For a mangrove dependent community of Pangaimotu in Vavau in Tonga tourism development offers better income from employment opportunities. Yet reclaiming mangrove areas for tourism development is likely to impact on fisheries resources that have traditionally been the main form of livelihood for the community. It is argued that for small island communities, whenever development activities ignore the critical role of mangroves on fisheries resources, the wider implications to the community are also overlooked.... |

| This study looked at the dynamics of conditional correlations and hedging strategies in the US main cotton producing regions. A two-step procedure was utilized to model, estimate, and analyze volatility, conditional correlations, and the optimal hedge ratios using spot prices in the Delta, Southeast, Southern Plains, and the Southwest regions and the New York commodity exchanges December futures contracts. The results indicate that volatilities in most of the regions are asymmetric and persistent. The derived conditional correlations and the optimal hedging ratios are dynamic although they do not have unit root. Moreover, the changes in agricultural policies altered the dynamics of correlations and producers' hedging strategies in the Delta, Southeast,... |
