  • Political economy or economics is a study of mankind in the ordinary business of life; it examines that part of individual and social action which is most closely connected with the attainment and with the use of the material requisites of wellbeing. Thus it is on the one side a study of wealth; and on the other, and more important side, a part of the study of man. For man's character has been moulded by his every-day work, and the material resources which he thereby procures, more than by any other influence unless it be that of his religious ideals; and the two great forming...

  • Before tracing the beginnings of renewed municipal life in Northern Italy, we must consider the conditions of land and people, which first rendered possible and then fostered the spirit of local independence of which such beginnings were the natural expression. To do this we must commence our researches with the first domination of the Lombards in the country. In detail the story of the conquest of Northern Italy by the Lombards under Alboin, in 568, hardly differs materially from that of the inroads of other barbarian tribes of the north on the fertile plains of Italy.

  • Far over the eastern half of Europe extends a vast and mighty plain, spreading thousands of miles to the north and south, to the east and west, in the north a land of forests, in the south and east a region of treeless levels. Here stretches the Black Land, whose deep dark soil is fit for endless harvests; here are the arable steppes, a vast fertile prairie land, and here again the barren steppes, fit only for wandering herds and the tents of nomad shepherds. Across this great plain, in all directions, flow myriads of meandering streams, many of them swelling into noble rivers, whose...

  • “Be it deep or shallow, red or black, sand or clay, the soil is the link between the rock core of the earth and the living things on its surface. It is the foothold for the plants we grow. Therein lays the main reason for our interest in soils.” --- Roy W. Simonson, USDA Yearbook of Agriculture, 1957. The British naturalist Charles Darwin (1809–1882) was probably the first scientist to examine a soil profile and suggest factors responsible for the structure of the various layers.

  • In addition to ovulation, another critical function occurs during the menstrual cycle. The woman’s body must be prepared in case fertilization occurs. Everything must be ready to nurture the developing embryo. Dur- ing the first two weeks of the cycle, estrogen causes the lining of the uterus to thicken. There is also an increase in the amount of blood that flows to this area. During the second half of the cycle, after ovulation has occurred, the follicle (now without the egg cell) develops into a yellow-colored body, the corpus luteum.

  • • There is need to diversify urban-development activities within the municipality. An outward spread of these development activities and the creation of satellite towns in areas such as Olkaria, Sulmac and Sharlimar would minimise the pressure on the natural environment, land, forests, air and water resources, as well as on the capacities of socio-economic infrastructures such as sewerage and water supply facilities and roads. This will also result in a reduction of land use conflicts, which is a major cause of environmental degradation in any given urban scenario. ...

  • America’s public lands and Federal waters provide resources that are critical to the nation’s energy security. To encourage robust exploration and development of the nation’s resources, the Administration has offered millions of acres of public land and Federal waters for oil and gas leasing over the last two years. Oil production from the Outer Continental Shelf increased more than a third – from 446 million barrels in 2008 to more than 600 million barrels of estimated production in 2010.

  • Almost any land contains enough food for the growing of good crops, but the food elements may be chemically unavailable, or there may be insufficient water to dissolve them. It is too long a story to explain at this place,--the philosophy of tillage and of enriching the land,--and the reader who desires to make excursions into this delightful subject should consult King on "The Soil," Roberts on "The Fertility of the Land," and recent writings of many kinds. The reader must accept my word for it that tilling the land renders it productive. I must call my reader's attention...

  • The Cakchiquels, whose traditions and early history are given in the present work from the pen of one of their own authors, were a nation of somewhat advanced culture, who occupied a portion of the area of the present State of Guatemala. Their territory is a table land about six thousand feet above the sea, seamed with numerous deep ravines, and supporting lofty mountains and active volcanoes. Though but fifteen degrees from the equator, its elevation assures it a temperate climate, while its soil is usually fertile and well watered.

  • The phenomenon of land grabbing is heavily being discussed. First efforts to explain this land rush focused strongly on the government or government-supported activities of water- and fertile-land-scarce Arab and Asian countries. In the course of 2009 and 2010, indications that other actors are at least equally relevant became more and more substantial. Especially the fi- nancial sector seemed to have been overlooked. Then, different sources like the World Bank or the OECD came up with indica- tions of how profound the role of the financial sector is.

  • These last individuals have generally gone beyond the use of acidified chemical nutrients and toxic sprays, yet their means of producing food are often dependent on extracting fertility from one piece of land in order to enrich another, i.e. “robbing Peter to pay Paul.” Meanwhile the overall fertility of the Earth continues to decline.

  • Soil erosion affects a large part of the Earth surface, and it represents one of the most relevant environmental problems worldwide. Intense land degradation processes that destroyed civilizations in the past are still going on at present. Accelerated soil erosion is one of the main soil threats, as the natural balance between soil formation and loss may be seriously compromised, leading to desertification and permanent loss of fertility and protective function. Soil erosion is not only related to agricultural activities and farming practices, but also to land management in general....

  • The use of industrially manufactured nitrogen (N) fertilizers increased rapidly in developed countries between 1960 and 1980. This facilitated a large increase in the production of feed and food grains (maize, wheat, and rice) per unit of cultivated land, but in some regions it also contributed to enrichment of surface and groundwater with various forms of nitrogen. Fertilizer, however, is not the only source of nitrogen that can cause contamination of surface waters.

  • Farm mechanization helps in effective utilization of inputs to increase the productivity of land and labour. Besides it helps in reducing the drudgery in farm operations. The early agricultural mechanization in India was greatly influenced by the technological development in England. Irrigation pumps, tillage equipment, chaff cutters, tractors and threshers were gradually introduced for farm mechanization.

  • Consider my parents. My mother did not know any geomorphology or landscape ecology. Yet she enjoyed her familiar, Southern US rural land- scapes. My father enjoyed the fertility of the soils in the Shenandoah Valley in Virginia; he admired a good field. On visits around, he would take a spade and turn the soil to see whether it might make a good garden. He always knew what watershed he was in, what crops were growing where. He loved a good rain. Both enjoyed the changing seasons, the dogwood and redbud in the hills in the spring, the brilliant and subtle colours...

  • Every year, farm operators apply more than 12 million tons of nitrogen fertilizer and 8 million tons of phos- phorus fertilizer to agricultural land in the U.S. Unless carefully managed, much of it is carried off the fields by runoff or percolates into drainage systems, eventually ending up in streams, rivers, lakes and underground aquifers. Animal manure from livestock is also an important contributor to nutrient pollution, particularly phos- phorus.

  • Mistakes and students go together. Otherwise, pupils would be teachers. English – a language of few infallible rules – is fertile land for blunders and I have been listening to and committing them for years. One day I started to keep a list of the most common slips and ended up with around three hundred. After eliminating the least frequent I listed the remainder, which you’ll find below. Even though I have strived to include the most common errors this list is – as many others – arbitrary.
