Eight years after releasing its first report on land grabbing, which put the issue on the international agenda, GRAIN publishes a new dataset documenting nearly cases of land grabbing around the world. It exposed how a new wave of land grabbing was sweeping the planet in the name of addressing the global food and financial crises. On the other hand, food corporations and private investors, hungry for profits in the midst of the deepening financial crisis, see investment in foreign farmland as an important new source of revenue.
By far the greater part of Asia remains uncultivated, primarily because climatic and soil conditions are unfavourable. Conversely, in the best growing areas an extraordinarily intensive agriculture is practiced, made possible by irrigating the alluvial soils of the great river deltas and valleys. Of the principal crops cultivatedrice, sugarcane, and, in Central Asiasugar beets require the most water.
Humans are transforming the Earth through our carbon emissions. Arctic sea ice is shrinking, seas are rising, and the past four years have been the hottest since record-keeping began. Environmental scientist Erle Ellis has studied the impact of humanity on the Earth for decades, with a recent focus on categorizing and mapping how humans use the land—not just now, but in the past.
Australia is a major agricultural producer and exporter, with overemployed in agriculture, forestry and fishing as of February Australia leads the world with 35 million hectares certified organic, which is 8. There are three main zones: the high rainfall zone of Tasmania and a narrow coastal zone used principally for dairying and beef production ; wheat, sheep zone cropping principally winter cropsand the grazing of sheep for woollamb and mutton plus beef cattle and the pastoral zone characterised by low rainfall, less fertile soilsand large scale pastoral activities involving the grazing of beef cattle and sheep for wool and mutton. Australia produces a large variety of primary products for export and domestic consumption.
According to the RAS, tens of millions of acres of land traditionally used for small-scale or subsistence farming are being completely neglected with even their ownership under question. Although the state-owned disputes the RAS figures, even it puts the amount of unused farmland at 40m hectares, indicating that despite the efforts of successive post-Soviet governments to tackle land reform, deep-rooted issues still remain. Federal government landholdings—belonging to ministries, the presidential administration, the armed forces and security services—are vast, largely secret and frequently exploited for the private convenience and profit of officials.
Humans have been cultivating crops for thousands of years becoming experts at producing more yield over time. Agriculture is vital to feeding the world population and is a key component to the economy in many countries. The British Agricultural Revolution led to the mechanization of farming, the 20th century brought the gas-powered tractor and around the same time, the development of factory farms or concentrated animal feeding operations.
January 25, — The rapid expansion of Asian and African cities, fueled by rural to urban migration will have a significant impact on croplands and yields by states a new study appearing in the Proceedings of the National Academy of Sciences of the United States. The loss represents as much as 2. Cities will encroach on farmland that is twice as productive as the average farm.
Our future crops will face threats not only from climate change, but also from the massive expansion of cities, a new study warns. This may not appear to be a huge figure at first glance, but on the regional scale the picture changes. Across countries and different crops, the effects of this loss vary and become more intense.
A farm is an area of land that is devoted primarily to agricultural processes with the primary objective of producing food and other crops ; it is the basic facility in food production. It includes ranchesfeedlotsorchardsplantations and estates, smallholdings and hobby farms, and includes the farmhouse and agricultural buildings as well as the land. In modern times the term has been extended so as to include such industrial operations as wind farms and fish farmsboth of which can operate on land or sea.
In the charts below, we see the average agricultural yield of particular crops over the long-term in the United Kingdom, from onwards. In the first chart, we have plotted cereal crops wheat, barley and oats. Overall, we see that improvements in cereal yields from the 19th century into the first half of the 20th century were relatively slow— by the s, yields were typically in the range of Productivity gains between the s and s was rapid, growing fold over this period.
