How does government policy affect land?

When private incentives differ from societal incentives, the influence of government policies and regulations can have a major impact on managing the natural resources. In the United States, 25% of arable land is regulated with the beneficial effects for soil conservation. Conservation tillage in the United States was part of the 1985 Food Security Act (FSA), which encouraged farmers to take erosion-control measures by providing farm subsidy payments. The US Food, Agriculture, Conservation, and Trade Act of 1990 (amendment to FSA) established financial penalties and ineligibility for most farmer program subsidies to farmers who produced agricultural crops on wetlands that were converted after enactment. This act also established the Conservation Reserve Program, providing an opportunity for the farmers to take highly erodible lands out of production by receiving annual rental payments from their 10-year contracts with the Department of Agriculture. The Federal Agriculture Improvement and Reform Act of 1996 introduced “planting” flexibility, giving farmers entering commodity programs freedom to choose crops on the contracted acreage. Under the same act, soil erosion control and wetland restoration regulations were improved. These few examples illustrate that government policies can slow land degradation.


How does mulching help vineyards?

The use of organic and inorganic mulches in vineyards conserves soil moisture by minimizing evaporation and improving soil infiltration ( Pinamonti, 1998; Chan et al., 2010; Medrano et al., 2015b ). In addition, organic mulches increase soil organic matter and improve soil structure and soil water-holding capacity ( Proffitt, 2013 ). The use of mulches also has a regulatory effect on T s ( Figs. 10.2 and 10.3 ). Such an effect depends on the type of material used and its color ( Pinamonti, 1998; Fourie and Freitag, 2010; Chan et al., 2010 ). In the case of dry grass mulching, our results show that it dampened T s over time and avoided T s extremes contrary to a bare cultivated soil situation ( Fig. 10.2 ). Contrary to the use of mulches, a clean tilled soil surface promotes evaporation on top layers and does not conserve soil moisture effectively, especially when done after rain ( Van Huyssteen and Weber, 1980 ). In turn, in the case of a bare soil with chemical weed control, the dry vegetation surface layer can have a mulch effect but soil cracking may occur (mainly in clay soils), which favors evaporation from deeper soil layers.


What are some examples of land degradation?

The westward Euro-American settlement of the US is replete with examples of land degradation and soil eros ion. Dabney et al. (2012) described water-driven soil erosion problems extending from the US southeastern coastal plain that began with clearing land of virgin timber for agriculture during the 1830s and, for an example, resulted in what was later described in 1910 as the badlands of Mississippi. The native range of the North American bison that includes the southern Great Plains, previously labeled the ‘Great American Desert’ by explorer Stephen Long in 1820 ( Price and Rathjen, 1986 ), similarly entered agricultural production at the beginning of the 1900s with the encouragement of railroads and land speculators ( Egan, 2006; Campbell, 1907 ). Fueling this migration to the Great Plains was an early claim of anthropogenical climate change that ‘rain follows the plow’ as professed with certainty by Cyrus Thomas who served as agriculturalist and naturalist for the 1871 Hayden expedition ( Bartlett, 1980 ). The ensuing cultivation implemented the widely adopted farming practices from Campbell’s ‘A Complete Guide to Scientific Agriculture as Adapted to the Semiarid Regions’ (1907) that promoted frequent residue-burying tillage using implements intended for maximum pulverizing of soil. That soil condition was intended to increase rain infiltration plus provide an evaporation-limiting dust mulch and an ‘ideal seedbed.’ However, some 16 million hectares of potentially erodible soil were exposed and eventually became the Dust Bowl of the 1930s.


Why is organic matter limiting in Andean agroecosystems?

Biomass production: Organic matter has become highly limiting in Andean agroecosystems (particularly in the Altiplano) due to competing uses of fuel, fodder, and soil fertility amendments, thus indicating a need for greater farm level biomass production.


What was the Bureau of Soils Bulletin 55?

The 1909 Bureau of Soils Bulletin 55 provided an impressively extensive survey of the US soil resource prefaced by recent investigations containing the notable claim that the soil was an ‘indestructible, immutable asset’ ( Whitney, 1909 ).


How does agriculture affect the environment?

The effects of land cultivation and soil erosion expand beyond the border of an agricultural field, state, or even country. Separate agricultural ecosystems are connected via a network of groundwater, streams, and rivers. Silt, sediments, nutrients, and other agricultural pollutants that are transported to streams, rivers, and ultimately marine systems can restrict the possibilities for navigation, irrigation, food production, and fisheries, and can affect water and air quality. Thus, the local ecological impacts of agricultural practices have been recognized globally. This has resulted in national and international policy frameworks including organizations such as: the Food and Agriculture Organization (FAO), the International Geosphere and Biosphere Program – Global Change in Terrestrial Ecosystems (IGBP – GCTE), the International Union of Soil Science (IUSS), Global Assessment of Soil Degradation (GLASOD), and Inter-Government Panel on Climate Change (IPCC), Global Soil Week (GSW), and Inter-Government Technical Panel on Soil (ITPS), all of which have been active in either research, communication, or assistance to countries requiring immediate soil conservation measures and agricultural improvement.


Why is it important to manage organic residues?

Improved management of organic residues would help to improve nutrient-use efficiency, while contributing to soil biological functioning and SOM storage. Further, the strategic application of inorganic fertilizers with organic resources offers a particularly useful tool for controlling nutrient release from a variety of organic materials and rapidly correcting nutrient imbalances, thus allowing farmers to maximize the potential of locally available organic resources.


What makes soil so important?

Soils help meet societal needs, providing food, energy, and nutrients. They also help minimize the impact of climate change and promote healthy ecosystems. Below are three reasons why soil is so important:


Why is soil important for life?

Soil provides the nutrients essential for plant growth, animal life, and millions of microorganisms. However, if soil becomes unhealthy, unstable, or polluted, the life cycle stops. Soil conservation focuses on keeping soils healthy through a combination of practices and techniques. Individuals committed to soil conservation help ensure that soil is fertile and productive, and protect it from erosion and deterioration.


What are the threats to soil conservation?

Threats to soil conservation. The primary threats to soil conservation are climate change and traditional farming practices, according to the United Nations. Traditional farming practices include the overuse of harmful pesticides that contaminate soils, slash-and-burn methods, and land overuse. Soil conservation aims to mitigate these threats.


How do pesticides affect the environment?

The use of pesticides can contaminate the soil, as well as nearby vegetation and water sources, with harmful chemicals . In addition to contamination, chemicals used on crops can be toxic to important beneficial insects, such as bees, as well as fish and bird populations.


How does overuse affect soil?

Land overuse. Overuse of land can limit soil’s ability to play its part in the global climate cycle. For example, overcutting forests and woodlands for timber and overgrazing pastures can far outpace the natural regrowth of vegetation, subjecting soil to increased exposure to erosion.


Why is no till farming important?

No-till farming protects the soil from moisture loss due to high temperatures because cover crop residue remains on the surface of the soil.


What is the role of soil in the environment?

Soil is home to many living things. Soil organisms ensure sustainable food systems and mitigate climate change. Plants and animals rely on soils for food, shelter, and more. Soil is also home to fungi, algae, and unicellular and multicellular organisms that are invisible to the naked eye, such as bacteria and protozoa.


What is Dutch agriculture?

Dutch agriculture is characterized by the growth of plants and crops in greenhouses. In greenhouses all aspects of growth can be artificially controlled, including the artificial imposition of climatic conditions and artificial growth patterns (i.e. hydroponics) and even the mechanical automation of farming.


What is the difference between selective breeding and genetic engineering?

Both genetic engineering and selective breeding aim to develop crops with desirable traits, but with selective breeding only traits that are natively found in the genome of the species can be isolated and expressed.


Why is it important to flood rice fields?

Therefore, flooding rice fields reduces the growth of these less robust pests without negatively affecting the rice crop. Flooding the fields also deters many kinds of vermin that would otherwise live in the soil and harm the rice plants because they cannot breathe underwater.


How does flooding rice fields reduce the need for herbicides and pesticides in rice farming?

Explain how flooding rice fields reduces the need for herbicides and pesticides in rice farming. Rice has a submerged growth state while most weeds do not. Therefore, flooding rice fields reduces the growth of these less robust pests without negatively affecting the rice crop.


Why are tropical plantations important?

Tropical plantations provide a unique source of income for locals in many countries because they produce crops, such as cocoa, rubber and tea, desired around the world that can only be grown in tropical climates.


Do tropical plantations produce raw materials?

However, the produce of these tropical plantations also tend to be simple raw materials that are mere ly the first step in a production process that yields more profitable products. While the communities do benefit from the production of the raw materials, there is greater profit in the production of finished goods.
