Climate change policy distortions in the wood and food market

The widespread shift of Australia’s wood products industry away from native forests to an agricultural regime–wood plantations–has enhanced forestry industry competitiveness. Wood now competes against food for agricultural land, water and other resources (including government support). New plantings have increased substantially since the mid 1990s via plantation managed investment schemes (MIS), arousing protest in the traditional agricultural sector and claims of unfair government policy treatment. This claim is investigated in an analysis that integrates the taxation treatment of plantation MIS with economics and forestry industry knowledge. Three methods are developed, and applied, to estimate the plantation MIS tax-based subsidy. Preliminary estimates indicate a tax-based subsidy to forestry through plantation MIS of between $0.9-1.2 billion over the five years ending 2008. The estimated subsidy is then incorporated in the Productivity Commission’s calculations of the effective rate of assistance (ERA) to industry groups from tariff, budget outlay and tax-based government policy. The ERA to Forestry & logging in 2008 was estimated to be 41.8 per cent: government assistance is equivalent to 42 per cent of Forestry & logging’s unassisted value added. The estimated plantation MIS tax based subsidy accounted for 77 per cent of the assistance. Assistance to Forestry & logging exceeds substantially the assistance (including drought related payments) to food growers: 7.2 per cent to Grain, sheep & beef and 17.3 per cent to Dairy cattle farming (a significant proportion was assistance that ceased in April 2008). A detailed examination of Australia’s proposed climate change policy concerning the land use sector indicates that agricultural resource use distortions created through plantation MIS arrangements are lightly to intensify.Environmental Economics and Policy,

Synthesis and Spectroscopic Study of Naphtholic and Phenolic Azo Dyes

Azo dyes are extremely important in variety of industries for variety of technical purposes. Hence, a series of naphtholic azo dyes 1-9 were synthesized via diazotization of substituted aniline derivatives followed by azo coupling with 2-naphthol. In similar manner, diazotization followed by azo coupling with phenol afforded phenolic azo dyes 10-17 in excellent yields. The chemical structures of all synthesized compounds were confirmed using analytical data and spectroscopic technique which include Uv-visible, IR, Mass spectra, 1H- and 13C-NMR

Evaluation of antibacterial activity of Pisidium guajava and Gongronema Latifolium

Pisidium guajava and Gongronema latifolium are local plants used traditionally in south-eastern Nigeria to treat ailments such as cough, loss of appetite, malaria and stomach disorders. In this study, aqueous and ethanolic leaf extracts of P. guajava and G. latifolium were screened for antibacterial activity against two clinically isolated organisms of the gastrointestinal tract, Escherichia coli and Staphylococcus aureus. Results obtained show that leaf extracts of both plants possess significant antibacterial activities against the two isolates. Ethanolic extracts showed more inhibitory effect compared to the aqueous extracts. Extracts of P. guajava exhibited higher inhibitory effect than that of G. latifolium. The diameter of zones of inhibition by the leaf extracts of P. guajava was 8 - 16 mm and 14 - 21 mm respectively for the aqueous and ethanolic extracts. The minimum inhibitory concentrations (MICs) were 5.0 and 0.625 mg ml-1 respectively for the aqueous and ethanolic extracts of P. guajava. For the extracts of G. latifolium, the diameter of zones of inhibition was between 6 and 10 mm while MICs were 10.0 and 2.5 mg ml-1 respectively for the aqueous and ethanolic extract
