To determine if the ‘NIMBY’ phenomenon explains the slow progress of wind farm development or do institutional factors need to be taken in to consideration?

The threats posed by climate change are placing governments under increasing pressure to meet electricity demand from low carbon sources. Wind energy has been has been identified as one of the main technologies to help in meeting these demands. The public in general favour wind energy yet proposed targets for generation capacity lag behind proposed goals. The N IM B Y phenomenon has been suggested as one of the reasons why we are behind our wind generation capacity targets. It is a common mistake to take general support for granted and expect the public to support developments when confronted with them in their local area. In many cases it is not unheard of that governing bodies whether social, political, regulatory, environmental, or cultural can overrule general public support and halt developments. Motives to halt developments will vary depending on the institutional body involved. The problem with the term N IM B Y is that it is too basic a term to describe the broad spectrum of complex motives that various institutions including the public may have against a development. This research focuses on a case study where the developer had major problems with the local county council and its wind energy policies when he was erecting a wind turbine despite having gained planning permission. A survey questionnaire was also used as part o f the research to seek the perception a rural community had on wind energy. The research findings and results are discussed with respect to the literature review highlighting a general public support for wind energy and the influence institutional bodies have over the progress of developments.

A nutrient balance model for typical Irish farming systems

The twin objectives of the work described were to construct nutrient balance models (NBM) for a range of Irish animal production systems and to evaluate their potential as a means of estimating the nutrient composition of farm wastes. The NBM has three components. The first is the intake of nutrients in the animal's diet. The second is retention or the nutrients the animal retains for the production of milk, meat or eggs. The third is the balance or the difference between the nutrient intake and retention. Data on the intake levels and their nutrient value for dairy cows, beef cattle, pigs and poultry systems were assembled. Literature searches and interviews with National experts were the primary sources of information. NBMs were then constructed for each production system. Summary tables of the nutrient values for the common diet constituents used in Irish animal production systems, the nutrient composition of the animal products and the NBMs (nutrient intake, retention and excretion) for a range of production systems were assembled. These represent the first comprehensive data set of this type for Irish animal production systems. There was generally good agreement between the derived NBMs values and those published in the literature. The NBMs were validated on a number of farms. Data on animal numbers, fertiliser use, concentrates inputs and production output were recorded on seven farms. Using the data a nutrient input/output balance was constructed for each farm. This was compared with the NBM estimate of the farm nutrient balance. The results showed good agreement between the measured balance and the NBM estimate particularly for the pig and poultry farms. However, the validation emphasised the inherent risks associated with NBMs. The average values used for feed intake and production parameters in the NEMs may result in the under or over estimate of actual nutrient balances on individual farms where these variables are substantially different. On the grassland farms there was a poor correlation between the input/output estimate and the NBM. This possibly results from the omission of the soil's contribution to the nutrient balance. However, the results indicate that the NBMs developed are a potentially useful tool for estimating nutrient balances. They also will serve to highlight the significant fraction of the nutrient inputs into farming systems that are retained on the farm. The potential of the NBM as a means of estimating the nutrient composition of farm wastes was evaluated on two farms. Feed intake and composition, animal production, slurry production was monitored during the indoor winter feeding period. Slurry samples were taken for analysis. The appropriates NBMs were used to estimate the nutrient balance for each farm. The nutrient content of the slurry produced was calculated. There was a good agreement between the NBM estimate and the measured values. This preliminary evaluation suggests that the NBM has a potential to provide the farmer with a simple means of estimating the nutrient value of his slurry.
