Land use change is an important driving force factor affecting the river water environment and directly affecting water quality. To analyze the impact of land use change on water quality change, this study first analyzed the land use change index of the study area. Then, the study area was divided into three subzones based on surface runoff. The relationship between the characteristics of land use change and the water quality grade was obtained by grey correlation analysis. The results showed that the land use types changed significantly in the study area since 2000, and water body and forest land were the two land types with the most significant changes. The transfer rate is cultivated field > forest land > construction land > grassland > unused land > water body. The entropy value of land use information is represented as Area I > Area III > Area II. The shift range of gravity center is forest land > grassland > water body > unused land > construction land > cultivated field. There is a strong correlation between land use change index and water quality, which can be improved and managed by changing the land use type. It is necessary to establish ecological protection areas or functional areas in Area I, artificial lawns or plantations shall be built in the river around the water body to intercept pollutants from non-point source pollution in Area II, and scientific and rational farming in the lower reaches of rivers can reduce non-point source pollution caused by farming.

The conversion of natural forest to agroforestry plantations and annual cropping systems alters the soil habitat and food resources for biota, including earthworms. Native earthworm species may disappear whereas exotic species with greater tolerance of disturbance and less niche specialisation may thrive. The objective of the study was to compare the earthworm diversity in managed forest and agroforestry systems, which were cultivated for mixed plantation and annual crop production on Mount Gede, Indonesia. All the habitats in the study area were impacted by humans. The forest habitat was a managed forest, with a permanent tree cover, whereas mixed plantation had a partial shrub cover. Meanwhile, homogenous plantation was cultivated with annual crops. Among 3787 individuals collected during July–October 2012, five Oriental earthworm species were identified in the soil communities of Mount Gede: Drawida nepalensis, Notoscolex javanica, Pheretima pura-group, Polypheretima moelleri, and Polypheretima sempolensis. Also, 18 species were found that are reported to be non-Oriental in origin. Anthropogenic disturbance of forests on Mount Gede, due to conversion into plantations, alters the earthworm environment by increasing soil water content, temperature and total phosphorous content, while decreasing organic carbon. N. javanica was the only native species to survive this deforestation, while the exotic Ocnerodrilus occidentalis and Pontoscolex corethrurus thrived, becoming the eudominant species. From the forest area to the mixed and homogenous plantations, the predicted decreasing diversity is evidenced by the lowering trend of Shannon’s diversity index. In conclusion, the land-use change into mixed plantations and annual croplands has reduced earthworm diversity in this region of Mount Gede, Indonesia.

Abstrak. Sub Sub DAS Cikujang merupakan salah satu bagian dari Sub DAS Cimanuk hulu yang dapat menyumbang sedimen ke waduk Jatigede yang berasal dari erosi sebagai akibat perubahan penggunaan lahan yang tidak sesuai dengan kondisi fisik lahan. Hasil kajian memperlihatkan  pola perubahan penggunaan lahan di Sub Sub DAS Cikujang periode 1994-2009, terjadi perubahan penggunaan lahan dari kawasan lindung menjadi kawasan budidaya seluas 742,20 ha. Kawasan lindung pada tahun 1994 seluas 3.213,03 ha menurun menjadi 2.470,83 ha pada tahun 2009 dan kawasan budidaya pada tahun 1994 seluas 9.532,41 ha meningkat menjadi 10.274,61 ha pada tahun 2009 dengan laju perubahan 185,55 ha/tahun. Laju penurunan luasan hutan primer mencapai 54,45 ha/tahun, dan pada tahun 2009 tidak terdapat lagi lahan dengan fungsi sebagai hutan primer. Laju penurunan luasan hutan sekunder mencapai 135,90 ha/tahun dari 2.995,25 ha pada tahun 1994 menjadi 2.451,65 ha pada tahun 2009. Pola perubahan penggunaan lahan di Sub Sub DAS Cikujang sebagian besar dipengaruhi dengan pola perubahan hutan primer dan hutan sekunder pada kawasan lindung. Sedangkan pola perubahan penggunaan lahan pada kawasan budidaya dipengaruhi pola perubahan lahan kebun campuran, tegalan/ladang, perkebunan, dan sawah Land-Use Change Pattern in Cikujang Catchment Area Abstract. Cikujang catchment area is one part of the subzone Cimanuk that can contribute sediment upstream reservoirs to Jatigede derived from erosion as a result of changes in land use that is not in accordance with the physical condition of the land. Based on analysis result of land-use change pattern in Cikujang catchment area in 1994 – 2009 period, land-use had changed 742,20ha from protected areas to cultivated areas, where protected area had decreased from 3.213,03ha in 1994 to 2.470,83ha in 2009 and cultivated area had increased from 10.274,61 ha in 1994 to10.274,61 ha in 2009 with changing rate ha/year. The rate of decreasing primary forest area was 54.45ha/year, as a result there was no land function as primary forest in 2009.  The rate of decreasing secondary forest area was 135,90ha/year ranging from 2.995,25ha in 1994 to 2.451,65ha in 2009. Land-use change pattern in Cikujang catchment area dominantly was influenced by changing pattern of protected forest and secondary forest in protected area, but in cultivated area land-use change pattern was influenced by changing pattern of farm, grassland, and rice field.

Researchers and federal and state agency officials have long been interested in evaluating location-specific impact of bioenergy energy crops on water quality for developing policy interventions. This modeling study examines long-term impact of giant miscanthus and switchgrass on water quality in the Cache River Watershed (CRW) in Arkansas, United States. The bioenergy crops were simulated on marginal lands using two variants of a Soil and Watershed Assessment Tool (SWAT) model. The first SWAT variant was developed using a static (single) land-use layer (regular-SWAT) and for the second, a dynamic land-use change feature was used with multiple land use layers (location-SWAT). Results indicated that the regular-SWAT predicted larger losses for sediment, total phosphorus and total nitrogen when compared to location-SWAT at the watershed outlet. The lower predicted losses from location-SWAT were attributed to its ability to vary marginal land area between 3% and 11% during the 20-year modeling period as opposed to the regular-SWAT that used a fixed percentage of marginal land area (8%) throughout the same period. Overall, this study demonstrates that environmental impacts of bioenergy crops were better assessed using the dynamic land-use representation approach, which would eliminate any unintended prediction bias in the model due to the use of a single land use layer.
