The Impact

In spite of hydrology and geology disciplines` are relatively well known in Iraqi management strategy, unlike soil and its distribution system. Thus, describing strong indicator for evaluating water pathways, minerals, and materials in different soils is necessary to reduce the associated risks. However, the aim of this research is identified the change in soil behavior by observation, and interpretation the facts for effective indication mode. This mode is evaluated some features and properties in (soil- water) horizons from a focus on land use change in (e.g built up and rural) areas compared with riparian sites in middle region of Iraq. The evaluation is included field sampling by using `Drill auger` instrument and laboratory tests for analysis. The results areinterpreted as onset of soil impairment indices under changing in human activities, agricultural practices, climate change and effect of water movement. The elements are considerably bound with silt and clay particles which ultimately minimize leaching ability to lower layers in each horizon. The free access of water and air allows rapid oxidation of elements and caused materials corrosion and the output of leaches which can contaminate ground water and surface water. Besides, some elements are negatively correlated with concentrations of calcium carbonate. The content of sulfur compound in assorted land uses is uneven and increased with increase water content or agitating time. Also, the sulfur oxidation even if small proportion in fill material lead to the output of polluted drainage water and attack construction material when structural backfill and for bulk fill. Thus, its significant to consider these features for ameliorative engineering behavior.

Abstract The influence of incentives on landowner’s decision-making regarding land-use change is an intriguing consideration when developing sustainable agricultural land policies. Owners of agricultural land in rural areas with varying characteristics and varying agricultural yields each year have varying views on changing or maintaining their land. The purpose of this study was to determine the effect of incentives on people’s attitudes toward maintaining or selling land (land-use change from agricultural land to non-agricultural land). This study employed a descriptive analysis to calculate the impact of incentives from the government on the decision to change or keep the land. The responses of 500 respondents were categorized as follows: 20-46.67 in favor of land change, 46.67-73.33 neutral, and 73.4-100 in favor of maintaining land. The analysis revealed that additional factors influence the decision to sell or maintain the land. However, some villages seek to preserve land through government incentives.

Currently, in the context of climate change, droughts, salinity intrusion, sea level rise etc. and through the reality, it can be seen that the structure of land use (land use) in Tra Vinh province has been impacted quite strongly. The salinity intrusion, flooding and drought have increased in recent years, requiring appropriately comprehensive and proactive solutions. First and foremost, it’s a solution to change the structure of land use in combination with the change of seed structure and crop production structure to ensure efficient and sustainable development. For an overview of these changes as well as predictions for later years, the assessment of the impact of sea level rise on the average scenario (2030) affects the structure of land use by 2030 compared to the land use data in Tra Vinh in 2016, the results show that the areas flooded under the scenario of climate change and sea level rise RCP6.0  in 2030 are at risk of land use change.[TT1]  The land area has the risk of land use change in the whole province is nearly 24,235 ha. In which the most affected land area is specializing in rice land occupies 71%, area aquaculture (11%), paddy land remaining (8%), especially 4% of residential land in rural areas will be affected, this will directly affect the lives of people in the shallow village. [TT1]Need to revise

AbstractChanges in land use and climate are the main drivers of change in soil organic matter contents. We investigated the impact of the largest policy-induced land conversion to arable land, the Virgin Lands Campaign (VLC), from 1954 to 1963, of the massive cropland abandonment after 1990 and of climate change on soil organic carbon (SOC) stocks in steppes of Russia and Kazakhstan. We simulated carbon budgets from the pre-VLC period (1900) until 2100 using a dynamic vegetation model to assess the impacts of observed land-use change as well as future climate and land-use change scenarios. The simulations suggest for the entire VLC region (266 million hectares) that the historic cropland expansion resulted in emissions of 1.6⋅ 1015 g (= 1.6 Pg) carbon between 1950 and 1965 compared to 0.6 Pg in a scenario without the expansion. From 1990 to 2100, climate change alone is projected to cause emissions of about 1.8 (± 1.1) Pg carbon. Hypothetical recultivation of the cropland that has been abandoned after the fall of the Soviet Union until 2050 may cause emissions of 3.5 (± 0.9) Pg carbon until 2100, whereas the abandonment of all cropland until 2050 would lead to sequestration of 1.8 (± 1.2) Pg carbon. For the climate scenarios based on SRES (Special Report on Emission Scenarios) emission pathways, SOC declined only moderately for constant land use but substantially with further cropland expansion. The variation of SOC in response to the climate scenarios was smaller than that in response to the land-use scenarios. This suggests that the effects of land-use change on SOC dynamics may become as relevant as those of future climate change in the Eurasian steppes.

The Impact

Soil properties are strongly influenced by the composition of the surrounding vegetation. We investigated soil properties of three ecosystems; a coniferous forest, a deciduous forest and an agricultural grassland, to determine the impact of land use change on soil properties. Disturbances such as deforestation followed by cultivation can severely alter soil properties, including losses of soil carbon. We collected nine 40 cm cores from three ecosystem types on the Roebuck Farm, north of Perth Village, Ontario, Canada. Dominant species in each ecosystem included hemlock and white pine in the coniferous forest; sugar maple, birch and beech in the deciduous forest; grasses, legumes and herbs in the grassland. Soil pH varied little between the three ecosystems and over depth. Soils under grassland vegetation had the highest bulk density, especially near the surface. The forest sites showed higher cation exchange capacity and soil moisture than the grassland; these differences largely resulted from higher organic matter levels in the surface forest soils. Vertical distribution of organic matter varied greatly amongst the three ecosystems. In the forest, more of the organic matter was located near the surface, while in the grassland organic matter concentrations varied little with depth. The results suggest that changes in land cover and land use alters litter inputs and nutrient cycling rates, modifying soil physical and chemical properties. Our results further suggest that conversion of forest into agricultural land in this area can lead to a decline in soil carbon storage.
