Assessing the Effect of Modifying Milking Routines on Dairy Farm Economic and Environmental Performance

The objective of this paper was to quantify the economic and environmental effects of changing a dairy farm’s milking start times. Changing morning and evening milking start times could reduce both electricity costs and farm electricity related CO2 emissions. However, this may also involve altering farmer routines which are based on practical considerations. Hence, these changes need to be quantified both in terms of profit/emissions and in terms of how far these milking start times deviate from normal operations. The method presented in this paper optimized the combination of dairy farm infrastructure setup and morning and evening milking start times, based on a weighting variable (α) which assigned relative importance to labor utilization, farm net profit and farm electricity related CO2 emissions. Multi-objective optimization was utilized to assess trade-offs between labor utilization and net profit, as well as labor utilization and electricity related CO2 emissions. For a case study involving a 195 cow Irish dairy farm, when the relative importance of maximizing farm net profit or minimizing farm electricity related CO2 emissions was high, the least common milking start times (06:00 and 20:00) were selected. When the relative importance of labor utilization was high, the most common milking start times (07:00 and 17:00) were selected. The 195 cow farm saved €137 per annum when milking start times were changed from the most common to the least common. Reductions in electricity related CO2 emissions were also seen when the milking start times were changed from most common to least common. However, this reduction in emissions was primarily due to the addition of efficient and renewable technology to the farm. It was deduced that the monetary and environmental benefits of altering farmer milking routines were unlikely to change normal farm operating procedures.

How does the Renewal of Trading Partners Affect the Economic Activity of Enterprises?

The article dwells upon the following issues connected with the behavior of enterprises in relation to their trading partners: what are the main characteristics of the process of renewal of trading partners? What is the share of enterprises actively changing their counterparts? Did the process of changing partners fade or gain momentum in the period from 1992 to 2000? Are there differences in the indicators of economic activity (prices, capacity and labor utilization rates, orders, stocks, investments, financial situation) between those who actively changed partners and those whose trading partner’s structure was more or less stable? What happens in times of crisis: do enterprises tend to preserve their business relationships or, conversely, do they have to revise them more actively? The unique REB surveys data makes it possible to get answers to these and other questions.

15 Climate Change and the Evolving Fulani Pastoralists Cattle Production System in Nigeria: A Need to Retool Extension and Innovation Services

The Fulani pastoralists of Nigeria, as in other parts of West Africa, are traditionally semi- sedentary or nomadic herders, and are often described as the largest nomadic group in the world. The combined effects of climate change and instability due to terrorist activities have led to massive displacement of many Nigerian Fulani households to Southwestern Nigeria in search of refuge, pasture and water for their cattle. The objective of this project was to examine the current Fulani cattle production system. In addition to obtaining data via focus groups and direct observation, a survey was administered to members of 600 Fulani pastoralist households to determine cattle production techniques and herding strategies adopted. The observation period occurred over a 24 month period in three Southwestern Nigeria states (Ogun, Kwara and Oyo). Herding activities were mapped by using hand-held Global Positioning System (GPS) to obtain the coordinates of grazing routes and settlements. The results showed that the Fulani operate a system of male social contract and kinship networks in labor utilization and movement of herds. Among semi-sedentary and sedentary groups, the grazing orbit was usually within 5km to 10km radius of the settlement, depending on the season. Of the households observed, very few had access to tap or treated water (0.9% in Oyo, 1.4% in Ogun and 0.2% in Kwara). In Ogun, rivers and streams provided water for the largest number of households, while in Kwara, hand-dug wells were the largest providers. In Oyo, streams and rivers provided water for a large percentage of the Fulani households. In addition to a lack of basic water infrastructure, the results further revealed low productivity of cattle due to poor management and the utilization of cattle breeds with low genetic potential. It is recommended that micro-ranches, enhanced by extension services that provide training on cattle management, be implemented for this population.

Dynamic scheduling model for the construction industry

Purpose Basic project control through traditional methods is not sufficient to manage the majority of real-time events in most construction projects. The purpose of this paper is to propose a Dynamic Scheduling (DS) model that utilizes multi-objective optimization of cost, time, resources and cash flow, throughout project construction. Design/methodology/approach Upon reviewing the topic of DS, a worldwide internet survey with 364 respondents was conducted to define end-user requirements. The model was formulated and solution algorithms discussed. Verification was reported using predefined problem sets and a real-life case. Validation was performed via feedback from industry experts. Findings The need for multi-objective dynamic software optimization of construction schedules and the ability to choose among a set of optimal alternatives were highlighted. Model verification through well-known test cases and a real-life project case study showed that the model successfully achieved the required dynamic functionality whether under the small solved example or under the complex case study. The model was validated for practicality, optimization of various DS schedule quality gates, ease of use and software integration with contemporary project management practices. Practical implications Optimized real-time scheduling can provide better resources management including labor utilization and cost efficiency. Furthermore, DS contributes to optimum materials procurement, thus minimizing waste. Social implications Optimized real-time scheduling can provide better resources management including labor utilization and cost efficiency.
