Desertification crisis affecting 168 countries worldwide, and studies show it? Were considered a global problem because of their economic, social and environmental, especially on developing countries dramatically, because they live in the ecosystems of dry lands most vulnerable to land degradation and desertification - those areas. On the economic front, land dry the population suffer from the poorest economic conditions because of desertification affects food productivity and reduces the potential regional and universality, as well as the food deficit in the threatened areas (arid and semi-arid), and a decrease of agricultural land and a shortage of water resources and poor quality and do not forget that the livelihoods of many farmers deteriorate? That desertification leads to the destruction of life as well as vegetable extinction of some groups of animals is one of the biggest reasons for the loss of biological diversity in which dramatically reduces the chances of food production. And from the social level, desertification in all continents happens except Antarctica affects the lives of millions of people ways, the impact of this desertification and drought on a large proportion of the poor in this land, and caused a decrease in the level of welfare of the individual dramatically, particularly education, health, utilities and services due to slow growth infrastructure and the varied levels of these causes of altered rates of
This report provides information about water logging and its adverse effects. The report finds that water logging has worst effects on productivity. It is agreed that one of the greatest problem in our agriculture land is “water logging”. This paper highlights the production loss or many different negative effects of water logging and highlights the economic loss due to the problem of water logging which threaten the sustainability of agriculture production. Water logging refers to the saturation of soil with water, usually through irrigation, resulting in a condition under which most crop plants cannot grow.
Weeds present in crop fields that compete with crop plants for light moisture and others essential nutrients. Resulting reduce quality and yields of crop and increase the coast of production (Samad et al., 2008). Weeds cause damage to both (khariph and rabi ) crops. What is weed? The recognition of plant as weeds is perhaps as old as agriculture itself.
This can have detrimental effects on us and ecosystems. What are the ecological consequences of pesticides? Super pests are emerging that are harder to eradicate. We’ve also seen emergence of new plant disease, one example is SDS (Sudden Death Syndrome). Pesticides can
Another negative effect would be the needed conditions for efficient farming, such as: adequate farm buildings, road access, transport facilities for marketing, drainage of wetlands, and sources of finance for farmers (Sidney 1). Some of the obstacles many farmers had to face were weather related crop failures, and high railroad freight charges throughout the rural regions (Hillstrom 58). Mechanized farming also disrupted age-old agricultural patterns, and the abolition of serfdom released the peasant from his bondage to the land (Burchell 73). The Industrial Revolution had more painful and immediate consequences than slowing the rate of economic growth (Ashton 3). “Various government schemes to finance the war debt led to monetary instability and uncertainty” (Ashton 3).
1.0 Introduction Tropical forest known as one of the greatest bastions of biodiversity in this planet receives a major threat poses by rapid deforestation. Biodiversity face the greatest global threat due to the intensification and expansion of agriculture (Tilman, 2001; Donald, 2004 & Green, 2005). The process of breaking up large patches of forest into smaller part is called forest fragmentation (Brown & Jacobson, 2005). Small fragments of forest typically exist after deforestation, urbanization, or other modified lands that are totally unsuitable for most species that occupied in the forest whether by nature or design. These phenomena may reduce biodiversity by making it more difficult for some species to either breed or find food (Wade, 2003).
It is a treacherous threat in every perspective. It may lead to consequences such as, genetic pollution, negative ecological impacts, economic costs, agricultural damage, lots of tourism, and had even threatened global biodiversity. According to GISP, “The impacts of invasive species are often immense, insidious and often irreversible (GISP, 2014).” Invasive species had been a difficulty in several countries and Japan is one of them. Especially after the dreadful experience of the invasion of the Redback Spiders and Apple Snails, we are informed about the danger and consequences of invasive species. As the MOE of Japan I assure that a solution should be soon addressed, established and conducted.
Introduction: The fantastic pace of development, all of the types of color revolutions, the explosion in transfer sector, the expansion of places and booming and mushrooming brand-new cities and haphazard operations of natural information have adversely affected ecology and the pure equilibrium. Environmental pollution in India provides increased manifold and is among the greatest problems confronting the present day civilization, which virtually means degrading the all-natural habitat and environment. Polluting of the environment, water pollution, land pollution, noise pollution are various other types of pollution. Near about 175 million hectares of property (35% of India’s total land area) is at the mercy of significant environmental degradation. A meagre 10.12 per cent of the total land spot of the national nation is usually under the tree go over.
In India, water erosion is the biggest reason of land degradation. Because of the over-population, the demand for food, energy, and housing have considerably altered land-use practices and severely degraded India’s environment. The growing population put immense pressure on land intensification at cost of forests and grazing lands because the demand of food could not increase substantially to population. Thus, horizontal extension of land has fewer scopes and relies mostly on vertical improvement that is supported by technical development in the field of agriculture i.e. HYV seeds, Fertilizers, Pesticides, Herbicides, and agricultural implements.
