Urban that they want. Here is a list

Urban agriculturecan help contribute to decreasing the net release of CO2 emissions, one of thegas that contributes to global warming, from activities in cities. If citiesare producing more food within their borders, bringing places of production andmarkets closer to each other, the transport of products can be reduced; this willcontribute to reducing carbon emissions and other pollutant gases.

Urbanagriculture is also a way to reducing the net discharge of CO2, because plantsand trees capture CO2. The captive capacity is at its highest in the developmentperiod of vegetation. Through agricultural activities in cities, urbanecosystems are kept persistently in their “primary production phase”; whichmeans that much more CO2 per surface area is captured than in natural systemslike tropical forests.

In cities, however, much of the carbon stored invegetation is likely to be quickly released through decomposition of organicmatter and there may be little lasting benefit. ·      Reducecarbon emission Thereason why urban farming in and on the buildings is gaining popularity isbecause they can have all the advantages of urban conditions. It providesenough sunlight, irrigation and privacy that the urban farmers need, and allthe facilities of an urban lifestyle that they want.

Here is a list ofbeneficial urban farming that can contribute to communities’ area: Theidea of growing food indoors in buildings, high rise buildings or rooftop in the cities isbecoming very popular around the world because of the rapid urbanization andlimited farming space, and so,  urban farming is also becoming very popular. Urban farming in and on the building or well-knownas zero-acreage farming could be one of theeasiest ways of growing our own food if we live in a high rise building. We could easily feed our friends and family as well as make some extra money. It’s possible togrow food indoors in containers, on your patio, balcony, rooftops, andvirtually anywhere, where they have some extraspace.1.3           Beneficial urban farming in and on the building Ina few urban communities, urban agriculture already has an important role inimproving food security and expanding the accessibility of dietary food for theurban poor.

They continuously to play a role in food security, however, theencroachment of urban sprawl onto farm land must be avoided they say. There is greatpotential for urban agriculture to play a greater role in food security if pollutionis reduced, sustainable farming practices are introduced and bans on urbanfarming is withdrawn, but these challenges may be difficult to overcome indeveloping countries due to the lack of the necessary infrastructure. This article alsoexplains about the planners tend to think that urban food growing is a messybusiness, and have little understanding of peoples need to grow food in cities.But others perception based a few article related for hundreds of millions ofurban people, it is a vital component of their livelihoods and during hardtimes it is an important survival strategy, and city dwellers are increasinglytrying to persuade planners to give them space for growing crops. This is true butnot only in developing countries, but also increasingly in the developedcountries, particularly in cities where unemployment is endemic.

In addition,many people like to take the chance to invest some portion of their energygrowing things as a leisure pursuit in the cities. Nowadays,the situation of urban agriculture varies enormously amongst created andcreating nations. In cities in developed countries, urban agriculture is dominatinglya recreational movement, instead of a dependable source of food.

The cost ofurban farming is too great to provide in a variable alternative to thesupermarket. In developed cities food security is highly demanding, there islittle incentive for widespread adoption of urban farming. The productivity ofurban agriculture in developed countries will rely upon mechanical technologiesand relative food production costs. If food becomes costlier and supplies isless secure, the advantages of urban agriculture may become more apparent.   As cities are grow, dietary are different. Mostof people who live in urban area are very demanding a more diversified diet,including fruits, vegetables, dairy, and meat, and are increasingly consumingprocessed foods. Going with these movements is the change of supply chains,affecting farmers, small- and medium-sized enterprises, and consumers.

Aprocedure has started, , which will continue for decades, that is transformingthe food systems from farm to fork.(Säumelet al., 2012) The major mission of urban agriculture based onthe author article is to feed the urban populations necessarily hinges onestimations of how much food can be grown within a city area.

The cities areexploding by human growth in this worlds. Today, the more people are living inurban areas than rural areas. More than 66 percent of the world’s people areexpected to live in cities by 2050, they very demanding for food for livingpurposes. Especially in low- and middle-income countries like Asia, Africa, andLatin America, to feeding urban populations has become an important and crucialchallenge.

Despite their populations density, cities do have more potential forfood growing in that area. 1.2           Farming in the cities There are other benefits to building integratedagriculture. Placing greenery on otherwise hard rooftops, for instance, canalleviate urban heat island effect (Yu, et al., 2008; Chen, et al., 2005).

Bringing production closer to consumption can reduce food miles, i.e. thedistance food travels in getting to the consumer’s plate (Severson, 2006),which decreases carbon emissions due to transport. Land outside cities need notbe set aside for intensive commercial farming, which of itself has manyhealth-related, social and environmental consequences. -Urban agriculture can be defined as co-locatingcrop cultivation within the city boundaries and this is one of potentialstrategy to those issues. By integrating of food production in and on thebuildings offers an avenue that does not impinge on the city`s many make usesfor available land -on author article stated that there are severalcrucial issues on that paper article will be several highlighted. First indepth of conventional commercial farming techniques have brought onirreversible damage to the land (Hillel, 1991); millions of hectares ofgrasslands, wetlands and forest were degraded and the cost of affection most ofecosystems have been damaged with significant loss of biodiversity (Wilson,1992).

The clearing of land for farming activities also effects of long-termperiod carbon sequestration by other permanent wood plantations (Wiliams,2003). Second, as the world population increases from the present 6.4 billionto 8 billion by 2025 (salim, 2004), there`ll no longer be enough arablefarmland (United States Census Bureau, 2003). This raises the spectre of foodcrises. The situation is aggravated by rampant urbanization because of moreland, previously used for agriculture, set aside to cope with growing cities.The prediction that the proportion of the world’s population that lives in thecities will increase from 47 percent in 2000 to 60 per cent by 2030 (UnitedNations, 2001) -A few developing countries in this world, theyare already concern about environmental issues especially in Hong Kong, thepromotion of sustainable environment especially on green roof have attracted alot of attention in recent years (Hui, 2009; Urbis Limited, 2007). They alreadybelieved that green roofs can help mitigate the unfavourable outcomes of UHI inthe city and bring the nature back to the urban area.

They not only can help tolower the urban temperatures, but enhance aesthetics and urban psychology, aswell as lessen pollutant concentrations and noise (Hui, 2006)  -Nowadays, many cities especially in urban areaare dealing with problems of urban heat island (UHI) and lack of greeneryspace. Some cities are seeking to improve sustainability by enhancing urbangreenery and promoting urban agriculture or farming (Mougeot, 2006; Smit Rattaand (Nasr, 1996). By preparing a few technologies by installing green roof withurban farming, its far feasible to obtain environmental, social and economicsustainability for residents especially in urban cities due to fact it is ableto contribute to mitigation of environmental problems, enhancement of communityfunction and improve of city food systems (Bay Localize, 2007; Canadian CEDNetwork, 2007; Kisner, 2008; Kortright, 2001; Lim and Kishnani, 2010).1.1           Introduction
