The evolving structure of a scientific citation network and its political effects 1 Introduction Existing literature describes academic citation networks and the structure of knowledge fields: However, little has been written to describe the specific structural changes over time of citation networks.

These threats have enormous human, social, and economic costs that are growing, cumulative, and unequally distributed.
These issues are all related to food—what we eat and how it is produced. The US industrial food system provides plentiful, relatively inexpensive food, but much of it is unhealthy, and the system is not sustainable. Although most US food consumption occurs within this industrial system, healthier and more sustainable alternatives are increasingly available.
Moving toward a healthier and more sustainable food Unionizing revision essay will involve tackling longstanding challenges and addressing new and evolving demands. This position paper reviews the scientific basis for understanding the US food system and sustainability, identifies specific issues of concern, discusses key related policies and action opportunities, and outlines APHA goals.
By uniting multiple food system themes in a single statement, it aims to provide clarity, new emphases, and solid direction, encouraging the APHA to increase its activities and leadership to promote a more sustainable, healthier, and more equitable food system.
Background Overview of the US Food System A systems approach 1 to food enables consideration of the many intricately related factors involved in getting food from farm to consumer, as well as their implications for health. Food systems include inputs, mechanisms, and structures for food production, processing, distribution, acquisition, preparation, consumption, and metabolism.
Food systems are deeply entwined with many social issues. Overlapping food systems serve local, regional, national, and global levels; herein, the term refers to the national level, unless noted. APHA defines a sustainable food system as one that provides healthy food to meet current food needs while maintaining healthy ecosystems that can also provide food for generations to come with minimal negative impact to the environment.
A sustainable food system also encourages local production and distribution infrastructures and makes nutritious food available, accessible, and affordable to all.
Further, it is humane and just, protecting farmers and other workers, consumers, and communities. The Human Right to Food The right to food is a fundamental human right.
The four pillars of food security are availability, stability of supply, access and utilization. The United States has eroded the pillars of food security.
APHA can provide an important stimulus to help restore the pillars and ensure that our food system is sustainable.
Several recent APHA policies have extensively addressed obesity and diet-related disease issues. Fertilizers and pesticides contaminate soils, groundwater, and streams.
For instance, runoff into the Mississippi River has led to a Gulf of Mexico dead zone that in some recent years has been as large as the state of New Jersey. Contamination with animal waste produced within the industrial system is a concern for human and ecosystem health because the waste often contains pathogens, including antibiotic-resistant bacteria, dust, arsenic, dioxin and other persistent organic pollutants, antibiotics, and complex mixtures of hundreds of volatile organic compounds.
Energy Use Industrialized agriculture methods are fossil fuel intensive; the US food system accounts for an estimated Corn and soy are particularly heavy users among plants. Industrial meat production, especially beef, requires the most water—much of it to irrigate feed crops.
For example, by one estimate it takes more than L of water to produce grain and hay for each kilogram of industrially produced beef. The health and ecosystem threats are magnified when the modified genes in plant species are also used for food such as corn, rice, and soybeans and when these altered crops are grown outdoors.PC.
