The role of values in climate-related decision-making is a prominent theme of climate communication research. The present study examines whether forest professionals are more driven by values than scientists are, and if this results in value polarization. A questionnaire was designed to elicit and assess the values assigned to expected effects of climate change by forest professionals and scientists working on forests and climate change in Europe. The countries involved covered a north-to-south and west-to-east gradient across Europe, representing a wide range of bio-climatic conditions and a mix of economic–social–political structures. We show that European forest professionals and scientists do not exhibit polarized expectations about the values of specific impacts of climate change on forests in their countries. In fact, few differences between forest professionals and scientists were found. However, there are interesting differences in the expected values of forest professionals with regard to climate change impacts across European countries. In Northern European countries, the aggregated values of the expected effects are more neutral than they are in Southern Europe, where they are more negative. Expectations about impacts on timber production, economic returns, and regulatory ecosystem services are mostly negative, while expectations about biodiversity and energy production are mostly positive.

Benefit Cost

Increasing demand for maize in Nigeria has resulted in high use of inorganic fertilizers and these fertilizers are expensive for peasant farmers who dominate farming in the country. The use of inorganic fertilizers also results in hidden cost borne by man and the ecosystem. In a search for a cost-effective and safer alternative, six maize varieties were evaluated using moringa, banana-peel, maize-stalk fertilizer (MBM) both in solid and foliar forms. Gross benefit, net benefit and benefit-cost ratio (BCR) were used to determine enterprises with the highest economic returns. The results showed that maize varieties treated with 90 kg/ha of NPK had the highest grain yield which was significantly comparable with MBM. The application of 120N+50P+40K rate of MBM to single cross hybrid, SCH LY1312-1, resulted in the highest benefit-cost ratio (15.16). MBM is economically more viable than NPK Fertilizer and its application in the solid (powdered) form before planting produced double economic returns compared to foliar application. Single cross hybrids gave better economic returns when the fertilizer was applied in solid form.

Stocking Rates

A grazing trial conducted in subtropical Queensland examined the effect of four stocking rates (high, medium, low, very low) on beef production, economic returns and pasture stability. Liveweight gains of steers were recorded in legume sown pastures, over a five year period in which severe drought conditions prevailed. Although high stocking rates generated the highest levels of beef production per hectare, moderate rates generated the highest economic returns. The status of the dominant perennial tussock grass (Heteropogon contortus) was used as an indicator of pasture condition. While H, contortus declined in all treatments during the drought, populations were most persistent at the low stocking rate. The results provide clear evidence of a trade-off between ecologically optimal stocking rates and animal production. The highest net profit was derived from the medium stocking rate, which was more than 50% higher than the next most profitable stocking rate. However, at this stocking rate there was evidence of a decline in the dominant grass, H. contortus, which suggests that the medium stocking rate may not be sustainable over the long-term. The highest stocking rate paddocks all required supplementary feeding of stock and were poor both in economic return and ecological condition. The low stocking rate plots had the highest rates of liveweight gain per animal and had low ecological risk, but had low to negative returns on equity and were not sustainable economically. Key words: - stocking rates, black speargrass pastures, economics, range condition, drought.
