Pre-Columbian Agriculture in Mexico Carol J
Pre-Columbian Agriculture in Mexico Carol J. Lange, SCSC 621, International Agricultural Research Centers- Mexico, Study Abroad, Department of Soil and Crop Sciences, Texas A&M University Introduction The term pre-Columbian refers to the cultures of the Americas in the time before significant European influence. While technically referring to the era before Christopher Columbus, in practice the term usually includes indigenous cultures as they continued to develop until they were conquered or significantly influenced by Europeans, even if this happened decades or even centuries after Columbus first landed in 1492. Pre-Columbian is used especially often in discussions of the great indigenous civilizations of the Americas, such as those of Mesoamerica. Pre-Columbian civilizations independently established during this era are characterized by hallmarks which included permanent or urban settlements, agriculture, civic and monumental architecture, and complex societal hierarchies. Many of these civilizations had long ceased to function by the time of the first permanent European arrivals (c. late fifteenth-early sixteenth centuries), and are known only through archaeological evidence. Others were contemporary with this period, and are also known from historical accounts of the time. A few, such as the Maya, had their own written records. However, most Europeans of the time largely viewed such text as heretical and few survived Christian pyres. Only a few hidden documents remain today, leaving us a mere glimpse of ancient culture and knowledge. Agricultural Development Early inhabitants of the Americas developed agriculture, breeding maize (corn) from ears 2-5 cm in length to perhaps 10-15 cm in length. Potatoes, tomatoes, pumpkins, and avocados were among other plants grown by natives. -
The Diffusion of Process Innovation: the Case of Drip Irrigation in California
The Diffusion of Process Innovation: The Case of Drip Irrigation in California Rebecca Taylor; ARE University of California, Berkeley; [email protected] David Zilberman; ARE University of California, Berkeley; [email protected] Selected Paper prepared for presentation at the 2015 Agricultural & Applied Economics Association and Western Agricultural Economics Association Annual Meeting, San Francisco, CA, July 26-28 Copyright 2015 by Rebecca Taylor and David Zilberman.

The Diffusion of Process Innovation: The Case of Drip Irrigation in California Abstract: This article uses drip irrigation to illustrate the evolution of process innovations during their diffusion—undergoing several waves of improvements and coevolution with other production practices in order to move across applications and locations over time. First we integrate multiple data sources to trace the rich history of drip in California. We find that drip’s evolution has been consistent with 1) the threshold model, which emphasizes the tendency to first adopt a technology at locations where it is most valuable and 2) the real option value model, which suggests that crisis situations trigger major transitions. We highlight the role of the private and public sector in adapting process innovations to local needs and show the necessity of historical analysis and perspective in assessing a technology’s impacts. Second, we empirically investigate the productivity impacts of drip irrigation in California, focusing on changes in crop yields and farm income. We estimate a yield effect of drip ranging from 16-48%, depending on the crop and location, and an increase in farm income between 2.6-7.4% annually. -

The Indus Valley: Brief Overview of Harappan Civilization Copyright Bruce Owen 2007
Emergence of Civilizations / Anthro 341: Class 18 The Indus valley: Brief overview of Harappan civilization Copyright Bruce Owen 2007 − Geographic and ecological setting − A huge area compared to Mesopotamia or Egypt − generally hot and little rainfall − agriculture requires being close enough to a river to benefit from natural flooding, or irrigation, which was only done on a small scale − mostly alluvial soils without mineral resources, like Mesopotamia − although some places have outcrops of stone useful for tools, jewelry, etc. − highly unstable Indus river and its tributaries, shift course frequently − many sites are located along abandoned, dry river beds − rivers are mostly navigable -- encouraging communication and exchange − Pakistan floodplain − combines the best features of Sumerian alluvium and the Nile − topographically similar to Sumer − rivers flood and form natural levees − making irrigation easy with little need for large-scale canal systems − but the floods come at a convenient time, like the Nile − Floods June to September − brings both water and rich silt − allows two different crops per year, without large investment in canals or other works − While flood water is high, plant cotton or sesame − keep water in with low banks − harvest as waters recede − after the flood, plant wheat or barley − enough water remains in soil to support the plants without major additional irrigation − harvest in March to April, a few months before the next flood − this is how people traditionally farmed in the region in recent times, apparently -
New Irrigation Technologies
New Irrigation Technologies Isaya V. Sijali and Rose A. Okumu1 Abstract Lack of appropriate and affordable irrigation technologies geared towards poor farmers on small plots is a major constraint to the spread of irrigation in Kenya and elsewhere in sub- Saharan Africa. Most irrigation equipment used in conventional pressurised irrigation systems in Kenya is imported and costly. As equipment suppliers are few, farmers have to pay higher prices for equipment. To address these problems, therefore, appropriate technologies need to be identified and adapted to suit smallholder farmers. These technologies need to be a) appropriate, simple and, if possible, equipment should be made using local materials and skills, and b) affordable and have the potential to earn high returns on investment. Small-scale drip irrigation systems and human-powered pedal pumps emerged in Kenya in the late 1980s. They have continued to gain popularity in the 1990s and are making a significant impact on rural communities. The potential for these systems is still unexploited (only less than 2% has been exploited) because of many factors, including rampant poverty and lack of information, but there is an upward trend in their adoption. There is a need for continued development and adaptation of the technologies and programs to teach farmers how to use them, as has happened in Asia. Introduction In Kenya, as in many parts of sub-Saharan Africa, agriculture is the mainstay of the livelihood of the citizens. The country enjoys a variety of climates and soils but less than 20 percent of the land area is considered arable under rain-fed condition. -
Smart Irrigation Technology Stories
SUSTAINABLE COMMUNITIES Smart Irrigation Technology Stories - Three Communities, Three Experiences Summary A growing number of local agencies irrigate publicly-owned landscaped areas with smart irrigation technology to save water, energy, staff time and money. Smart irrigation technology acts like a thermostat for irrigation systems by responding to weather and moisture content in the soil and thus adjusting the amount of water provided. Estimates suggest that installing smart irrigation systems (also referred to as “controllers”) can reduce water use by 20 percent. Additional benefits may include reducing: • Energy costs related to pumping water. • Vehicle miles traveled by agency staff and related fuel costs. • Staff resources needed to manage Beacon Award: Local Leadership irrigation systems. Towards Solving Climate Change Three California communities, Woodland, The Beacon Award is a program of the Simi Valley, and Santa Clarita, use smart Institute for Local Government and the irrigation technology and shared their Statewide Energy Efficiency experiences and lessons learned. The three Collaborative. More information is cities participate in the sustainability and available at: climate change recognition program, the www.ca-ilg.org/BeaconAward. Beacon Award: Local Leadership toward Solving Climate Change. Understanding Smart Irrigation Systems Traditional irrigation systems typically operate on a timer and do not respond to weather conditions or to the amount of water a plant actually needs. Smart irrigation system technology consists of a computer-based system that interacts with irrigation controllers located at a park or other irrigated site. The centralized computer system1 interacts with field measurements to adjust watering in one of two ways: 1. Weather-based systems use on-site weather data to adjust irrigation to reflect changing weather conditions. -

Copyright © 2012 Occidental Arts and Ecology Center’s WATER Institute 1 INTRODUCTION Stormwater is water flowing on land surfaces during or within 24 hours of a precipitation event that is not infiltrated into the soil. Historically it has been viewed as a problem primarily of urban areas to be solved by the outmoded engineering practice of "pave it and pipe it." This method fails to properly manage stormwater in the uplands, leading to disastrous consequences: large, powerful volumes of water moving too fast, resulting in severe erosion and flooding in low-lying areas. -
Importance of Neolithic Civilization Stages of Agriculture Development 12000 to 9500 Years Ago • Hunters and Food-Gathers Stage Existed
Stages of agriculture development - Era of civilization- Importance of Neolithic civilization Stages of agriculture development 12000 to 9500 years ago • Hunters and food-gathers stage existed. • Stone implements (microliths) were seen throughout the Indian subcontinent. • Domestication of dog occurred in Iraq. • Earliest agriculture was by vegetative propagation (e.g., bananas, sugarcane, yam, sago, palms, and ginger). 9500 to 7500 years ago • Wild ancestors of wheat and barley, goat, sheep, pig, and cattle were found. 7500 to 5000years ago • Significant features were invention of plough, irrigated farming, use of wheel, and metallurgy and in Egypt, seed dibbling said to be practiced. 5000to 4000years ago • Harappan culture is characterized by cultivation of wheat, barley and cotton; plough agriculture and bullocks for drought. Indus Valley is the home of cotton. • Wheeled carts were commonly used in the Indus valley. • Harappans not only grew cotton but also devised methods for ginning / spinning / weaving. 4000 to 2000years ago • In North Arcot, bone / stone tools were found. • In Nevasa (Maharastra), copper and polished stone axes were used. First evidence of the presence of silk was found at this location. • At Navdatoli on Narmada river (Nemar, Madhya Pradesh), sickles set with stone teeth were used for cutting crop stalks. Crops grown were wheat, linseed, lentil, urd (black gram), mung bean, and khesari. • In Eastern India, rice, bananas, and sugarcane were cultivated. 2000-1500 years ago • Tank irrigation was developed and practiced widely. • Greek and Romans had trade with South India; pepper, cloth, and sandal wood were imported by Romans. • Chola King Karikala (190 AD) defeated Cheras and Pandyas, invaded Srilanka, captured 12000 men and used them as slaves to construct an embankment along the Cauvery, 160km along, to protect land from floods. -
Nature and Nurture Farm Design and Management Plan
NATURE AND NURTURE FARM DESIGN AND MANAGEMENT PLAN Jared Aslakson Yihan Li Michael Lordon Alexandria Peters A project submitted in partial fulfillment of the requirements for the degrees of Master of Science and Master of Landscape Architecture University of Michigan School of Natural Resources and Environment April 2017 Faculty Advisors: Jennifer Blesh Stanton Jones ABSTRACT This master’s project intends to explore the design process and management of restoration agriculture in Southeast Michigan. Our client, Nature and Nurture LLC. is a multi-faceted business owned and operated by Mike Levine and Erica Kempter. Between the two of them, they provide organic landscaping services, teach classes, sell organic, locally-adapted seeds, fruits, vegetables, and mushrooms to restaurants and stores throughout Southeast Michigan. The Levine and Kempter extended family has recently acquired 120 acres of property in Scio Township, near Dexter, Michigan. Much of the property has been conventionally farmed for 50 or more years, while other portions of the property are high- quality woodland and wetland. Ultimately, our clients would like to derive their income primarily from the farm. Moreover, they are committed to ecologically responsible farming and are interested in using organic practices, restoration agriculture, and agroecological techniques throughout the property. To that end, our role was to create a site plan that: does not damage the existing high-quality ecosystems on the site, is able to increase the quality of the soils in the conventionally farmed areas (metrics for quality include but are not limited to: soil organic matter, amount of organic nitrogen, phosphorous, and potassium), and is able to increase the site’s overall habitat quality.
