World Census of Agriculture

Much like its role as a discoverer of new knowledge and as a large consumer in the energy sector, education communities have a significant role in food security research and as a consumer in its school lunch programs, dormitory, athletic facility and healthcare enterprises.  Accordingly — in much the same way we follow the US Census Bureau’s monthly construction activity report — we follow a data point provided by the US Department of Agriculture (USDA) as one of our stars to steer by.

The World Agricultural Supply and Demand Estimates  is a monthly report published by the USDA that provides comprehensive forecast of supply and demand for major crops (global and United States) and livestock (U.S. only). The report provides an analysis of the fundamental condition of the agricultural commodity markets for the use of farmers, governments and other market participants.

Steeplechase Water Jump

The steeplechase event requires a combination of speed, endurance, and jumping ability, as athletes must clear the barriers while maintaining their pace and negotiating the water jump. The rules and specifications for the steeplechase event are set by the International Association of Athletics Federations the governing body for the sport of athletics (track and field) worldwide; with minor adaptations by the NCAA for intercollegiate competition.

Emma Coburn | University of Colorado Boulder

The steeplechase is a distance race with barriers and a water pit that athletes must clear during the race.  According to the NCAA Track and Field and Cross Country rulebook, the standards for the steeplechase water jump are as follows:

  1. Length: The water pit must be at least 3.66 meters (12 feet) long.
  2. Width: The water pit must be at least 3.66 meters (12 feet) wide.
  3. Depth: The water pit must have a minimum depth of 0.7 meters (2 feet 4 inches) and a maximum depth of 0.9 meters (2 feet 11 inches).
  4. Slope: The slope of the water pit must not exceed 1:5, meaning that for every 5 meters in length, the water pit can rise by no more than 1 meter in height.
  5. Barrier: The water pit must be preceded by a solid barrier that is 91.4 cm (3 feet) high. Athletes are required to clear this barrier before landing in the water pit.

These standards may be subject to change and may vary depending on the specific NCAA division (Division I, Division II, or Division III) and other factors such as venue requirements. Therefore, it’s always best to refer to the official NCAA rules and regulations for the most up-to-date and accurate information on the steeplechase water jump standards in NCAA competitions.

Land Measurement

In the United States, land surveying is regulated by various professional organizations and government agencies, and there are several technical standards that must be followed to ensure accuracy and consistency in land surveying.

The best practice for land surveying is set by the “Manual of Surveying Instructions” published by an administrative division of the United States Department of the Interior responsible for managing public lands in the United States. The manual provides detailed guidance on the procedures and techniques for conducting various types of land surveys, including public land surveys, mineral surveys, and cadastral surveys.

Manual of Surveying Instructions

Another important set of model standards for land surveying is the Minimum Standards for Property Boundary Surveys* published by the National Society of Professional Surveyors. These standards provide guidance on the procedures and techniques for conducting property boundary surveys, including the use of appropriate surveying equipment, the preparation of surveying maps and plats, and the documentation of surveying results.   Land surveyors in the United States are also required to adhere to state and local laws and regulations governing land surveying, as well as ethical standards established by professional organizations such as the American Society of Civil Engineers.

The Morrill Land-Grant Act of 1862 granted each state 30,000 acres of federal land for each member of Congress from that state to establish colleges that would teach agriculture, engineering, and military tactics. This legislation led to the establishment of many public universities, including the Texas A&M University, the University of Wisconsin and Michigan State University.

Municipalities usually have specific land use or zoning considerations to accommodate the unique needs and characteristics of college towns:

  1. Mixed-Use Zoning: Cities with colleges and universities often employ mixed-use zoning strategies to encourage a vibrant and diverse urban environment. This zoning approach allows for a combination of residential, commercial, and institutional uses within the same area, fostering a sense of community and facilitating interactions between students, faculty, and residents.
  2. Height and Density Restrictions: Due to the presence of educational institutions, cities may have specific regulations on building height and density to ensure compatibility with the surrounding neighborhoods and maintain the character of the area. These restrictions help balance the need for development with the preservation of the existing urban fabric.
  3. Student Housing: Cities with colleges and universities may have regulations or guidelines for student housing to ensure an adequate supply of affordable and safe accommodations for students. This can
    include requirements for minimum bedroom sizes, occupancy limits, and proximity to campus.
  4. Parking and Transportation: Given the concentration of students, faculty, and staff, parking and transportation considerations are crucial. Cities may require educational institutions to provide parking facilities or implement transportation demand management strategies, such as promoting public transit use, cycling infrastructure, and pedestrian-friendly designs.
  5. Community Engagement: Some cities encourage colleges and universities to engage with the local community through formalized agreements or community benefit plans. These may include commitments to support local businesses, contribute to neighborhood improvement projects, or provide educational and cultural resources to residents.

Comment on FERC Action

The Federal Energy Regulatory Commission is an independent agency within the U.S. federal government that regulates interstate transmission of electricity, natural gas, and oil. It oversees wholesale energy markets, pipeline infrastructure, and hydroelectric projects, ensuring fair rates and reliability. While independent, FERC operates under the Department of Energy’s umbrella but does not take direct orders from the executive branch.

FERC enforces energy laws, approves infrastructure projects, and regulates market competition. FERC plays a crucial role in balancing economic, environmental, and energy security concerns, aiming to maintain a stable and efficient energy system across the United States.  Since the U.S. shares interconnected electricity grids with Canada and Mexico, FERC’s decisions on transmission rules and pricing affect energy flows and grid reliability in both countries.

Our interest lies in closing a technical gap that exists upstream from the building service point and downstream from the utility supply point. Some, not all of it, can be accomplished with titles in the IEEE catalog.

Given the dominance of vertical incumbents in the electric power domain, we have submitted a tranche of reliability concepts into the ASHRAE, NFPA and ICC catalogs — not so much with the expectation that they will be gratefully received — but that our proposals will unleash competitive energies among developers of voluntary consensus standards.

One of our proposals was heard at the April-May meetings of the International Code Council.  We are happy to discuss the outcome of that proposal any day at the usual hour.

Readings / The Administrative State

In power system engineering, availability and reliability are two important concepts, but they refer to different aspects of the system’s performance.

Reliability:

  • Reliability refers to the ability of a power system to perform its intended function without failure for a specified period under given operating conditions. It is essentially a measure of how dependable the system is.
  • Reliability metrics often include indices such as the frequency and duration of outages, failure rates, mean time between failures (MTBF), and similar measures.
  • Reliability analysis focuses on identifying potential failure modes, predicting failure probabilities, and implementing measures to mitigate risks and improve system resilience.Availability:
  • Availability, on the other hand, refers to the proportion of time that a power system is operational and able to deliver power when needed, considering both scheduled and unscheduled downtime.
  • Availability is influenced by factors such as maintenance schedules, repair times, and system design redundancies.
  • Availability is typically expressed as a percentage and can be calculated using the ratio of the uptime to the total time (uptime plus downtime).
  • Availability analysis aims to maximize the operational readiness of the system by minimizing downtime and optimizing maintenance strategies.

Reliability focuses on the likelihood of failure and the ability of the system to sustain operations over time, while availability concerns the actual uptime and downtime of the system, reflecting its readiness to deliver power when required. Both concepts are crucial for assessing and improving the performance of power systems, but they address different aspects of system behavior.

 UPDATED POLICIES ON U.S. DECARBONIZATION AND TECHNOLOGY TRANSITIONS


June 15:FERC Finalizes Plans to Boost Grid Reliability in Extreme Weather Conditions

On Monday June 13th, Federal Energy Regulatory Commission commissioners informed the House Committee on Energy and Commerce that the “environmental justice” agenda prohibits reliable dispatchable electric power needed for national power security. One megawatt of natural gas generation does not equal one megawatt of renewable generation. The minority party on the committee — the oldest standing legislative committee in the House of Representatives (established 1795) — appears indifferent to the reliability consequences of its policy.

Joint Federal-State Task Force on Electric Transmission

“Our nation’s continued energy transition requires the efficient development of new transmission infrastructure. Federal and state regulators must address numerous transmission-related issues, including how to plan and pay for new transmission infrastructure and how to navigate shared federal-state regulatory authority and processes. As a result, the time is ripe for greater federal-state coordination and cooperation.”

Goat farming is an important source of livelihood for many small-scale farmers in developing countries, particularly in regions such as sub-Saharan Africa and South Asia. The FAO estimates that more than 90% of the world’s goats are raised in developing countries, where they provide a critical source of food and income for rural communities.

Overall, the global goat farming industry continues to grow, driven by increasing demand for goat meat and milk products, as well as the potential for sustainable agriculture practices.

Advantages:

Low start-up costs: Goat farming requires relatively low start-up costs compared to other types of agriculture. Goats are small animals that do not require much space, and they can be raised in a variety of environments, from small backyard farms to large commercial operations.

High productivity: Goats are known for their high reproductive rate, which allows farmers to increase their herd size quickly. They are also efficient at converting food into milk and meat, making them a profitable investment for farmers.

Multiple uses: Goats can be raised for meat, milk, and fiber, making them a versatile livestock option. Additionally, their manure can be used as fertilizer, and they can be used for weed control on farms and other properties.

Sustainable farming: Goat farming can be a sustainable agricultural practice, as goats do not require large amounts of feed or water, and they can be raised on marginal lands that are unsuitable for other types of agriculture.

Disadvantages:

Predation: Goats are vulnerable to predation by coyotes, dogs, and other predators, which can be a significant problem for farmers, especially in rural areas.

Disease susceptibility: Goats are susceptible to a variety of diseases, some of which can be difficult to diagnose and treat. Additionally, some diseases can be transmitted to humans, making it important for farmers to take precautions when handling their animals.

Market volatility: The demand for goat products can be volatile, and prices can fluctuate significantly based on supply and demand. This can make it challenging for farmers to predict their income and manage their finances.

Labor intensive: Goat farming can be labor-intensive, especially during kidding and milking seasons. This can make it difficult for farmers to manage their workload, especially if they have a large herd.
