Agricultural use of wetlands: opportunities and limitations

wet farming definition

The main conservation benefit these systems have against storms and is the ability to reduce the speed and height of waves and floodwaters. Moisture can be conserved by eliminating weeds and leaving crop residue to shade the soil. It is of vital importance that agronomists, environmental scientists and local stakeholder groups cooperate to strive for the best combinations of land uses and other measures and for their actual implementation. In contrast, high water during lake marsh phase causes turnover in plant populations and creates greater interspersion of element cover and open water, but lowers overall productivity. Many river-dwelling fish species spawn in aquatic vegetation on floodplains and the fish larvae feed on the floodplains, so that fisheries can be strongly enhanced by water management allowing regular river flooding. Village and Household Economies in India's Semi-arid Tropics, Johns Hopkins University Press, Baltimore. Definition: An agricultural system practiced in the Mediterranean style climates of Western Europe, California, and portions of Chile and Australia, in which diverse specialty crops such as grapes, avocados, olives, and a host of nuts, fruits, and vegetables comprise profitable agricultural operations.

1. AGRICULTURAL AND FARM SYSTEMS

wet farming definition

This can bedone any number of ways, such as by using the water faucet at asink, shower or bathtub, or by swimming in a pool, river or ocean. From the early beginning of agricultural activities, such riverine wetlands have been recognized as valuable land areas for food and fodder production, because they have fertile soils as a result of regular sediment deposition during flood events. What such systems at this sub-divisional level have in common is that each is artificial: each is based upon or draws elements from higher-level natural and social systems; and each also contains elements which are purposefully created by some human agency in order to meet its needs. It also addresses a number of recent developments which will lead to pressure to reclaim and destroy natural wetlands, i. Wetlands have unique characteristics: they are generally distinguished from other or based on their and on the types of that live within them. · Abstract or concrete depending on whether or not they are conceptual or physical in nature.

Hydrochemistry within wetlands is determined by the , , nutrients, , soil composition, , and the sources of water. Order Level 2 systems can be viewed as aggregations often interactive of constituent Order Level 1 systems. Wet Rice Agriculture Asia for Educators Columbia University Wet Rice Agriculture In wet rice agriculture, seeds are sown in small seedbeds; the seedlings are then transplanted one by one to prepared paddy fields. This might be their sole purpose; e. Dordrecht: Kluwer Academic Publishers; 1992. This practice has become especially popular in Asia and the South Pacific. If, over time, the farm system is not biologically and economically sustainable or causes resource degradation, as discussed in Sections 6.

Intensive Wet Rice Farming

wet farming definition

This is of particular concern in temperate coastal systems. These sediments move towards larger and more sizable waterways through a natural process that moves water towards oceans. Most nutrients, such as , , , and are found within the soil of wetlands. Each such sub system may then be further disaggregated into commodity-based industry systems of Order Level 14 such as for coconuts, rubber, wheat, coffee, fish etc. To replace these wetland , enormous amounts of money would need to be spent on plants, dams, levees, and other hard infrastructure, and many of the services are impossible to replace.

Once the system begins operating, certain components of it the resource-generating activities and by-products of the enterprises will replenish the pool. Other examples are offered by the semi-nomadic livestock farmers of West Asia who sometimes operate as individual households and sometimes as members of a collective. Successful dryland farming is possible with as little as 230 millimetres 9 in of precipitation a year; higher rainfall increases the variety of crops. Because the rice stays dry throughout and does not undergo any pre-cooking or contact with water there is a minimal risk of contamination with pathogenic microbes. Strictly speaking, resources should be shown as flowing directly only to processes, since this is the level subsystems of Order Levels 1 and 2 at which they are actually used.

Wet Rice Agriculture

Element 6, resource-generating activities: In the example of Figure 1. Fens and bogs in the Netherlands: vegetation, history, nutrient dynamics and conservation. Research is needed to explore which combinations of land use and water management are optimal for supporting local communities in a sustainable way. However, the assessment also showed that this major accomplishment has been realized at the expense of major losses in biodiversity, disruption of global element cycles, problematic eutrophication and toxification of our freshwater resources, and loss of regulating ecosystem functions. Obviously these goals vary widely with culture, tradition and the degree of commercialisation and external influences to which the household is exposed.

Farmable Wetlands Program

Rice hulls with their high silica content have been used in a wide variety of situations including the manufacture of pressed insulation board, cement tiles and cement breeze blocks, in the glass industry and for road surfacing. That does not imply, however, that low-intensity agricultural activities in a large wetland area could not go together with a high biodiversity and other ecosystem services. The nutrients contained in the wastewater sustain fish farms and agriculture. . They have been classified in various ways as reviewed by Fresco and Westphal 1988 who also present an ecologically-based classification and typology of farm systems.
