Historical Land Use

Agriculture on the Indian sub-continent dates back to the fourth and third millennia BC, but only in more recent times did its intensity escalate in a major way. During the colonial era, the British established that the hilly areas of Sri Lanka were suitable for the rearing of coffee (Coffea arabica), for which much of the arable land of the island was extensively cultivated. Later, however, resulting from the severe impact of “Coffee Rust,” caused by the fungus Hemileia vastatrix, the coffee industry of Sri Lanka declined dramatically. Former coffee plantations were abandoned, but are still distinguishable as damaged areas. The truncation of coffee growing on the island created vacant room for another cash-crop.

Past Land Use

The evaluation of the impacts of land-use change on the water resources has been, many times, limited by the knowledge of past land use conditions. Most publications on this field present only a vague description of the past land use, which is usually insufficient for more comprehensive studies. This study presents the first reconstruction of the historical land use patterns in Amazonia, that includes both croplands and pasturelands, for the period 1940-1995. During this period, Amazonia experienced the fastest rates of land use change in the world, growing 4-fold from 193,269 km2 in 1940 to 724,899 km2 in 1995. This reconstruction is based on a merging of satellite imagery and census data, and provides a 5'x5' yearly dataset of land use in three different categories (cropland, natural pastureland and planted pastureland) for Amazonia. This dataset will be an important step towards understanding the impacts of changes in land use on the water resources in Amazonia.

A survey was carried out to investigate the acidification due to acid changes of different land use patterns. The results showed that soil acidification happened in the arable land and forest land in topsoil of 0~10 cm depth, 0.42 and 0.24 pH unit-1 lower than that of in 80~100 cm depth. The lowest cation exchange capacity (CEC) (11.99 cmol·kg-1) was got in the topsoil of paddy soil, while the highest one was in the topsoil of grassland with 19.26 cmol·kg-1. A catastrophe point of cation exchange capacity of soils was found between 20~30 cm except for orchard soil. Organic matter in forest soil decreased sharply by 2.21% in 0~10 cm as compared with that of in 80~100 cm and little decrease about 0.97% was found in the orchard soil. The pH and magnetic susceptibility showed similar variation trend. Multiple linear regression analysis showed that there was a negative relationship between pH and low magnetic susceptibility. Our results also showed that the free iron, low magnetic susceptibility and amorphous ferric oxide were the main factors on the changes of pH in the arable land and forest soil, grassland and paddy soil, and the orchard soil, respectively.

Planning Policies

This paper considers the impact of existing land use patterns on housing supply price elasticities in local areas of England, under existing planning policies. The paper demonstrates that, despite common national planning policies, local supply responses to market pressures vary considerably, because of differences in historical land uses. The study area covers the Thames Gateway and Thames Valley, which lie to the east and west of London respectively. However, whereas the latter is one of the wealthiest areas of England, the former includes some of the highest pockets of deprivation and was a government priority area for increasing housing supply. Due to differences in historical land use and geography, the price elasticity in the least constrained area is approximately six times higher than the most constrained.

Stream Systems

Land use influences the biodiversity of stream systems by changing the chemical composition of the water and the physical structure of the habitat. The present study evaluated the influence of these processes on the diversity metrics of Odonata at regional and local scales, testing the hypothesis that the two odonate suborders Anisoptera and Zygoptera will respond differently to habitat and landscape variables. The study focused on 13 sites in the municipality of Barcarena, Pará, Brazil. We found no significant impact from regional factors, although anisopterans were more affected by water temperature and Habitat Integrity Index (HII). The HII indicated that the local forest was stable, but anisopteran richness was negatively correlated with HII. It was indicating that these species favoured open areas with less riparian cover. Even though zygopterans did not exhibit a similar systematic pattern, the reduced abundance of Chalcopteryx rutilans, a species associated with better-preserved habitats, may indicate that some sites lack the habitat integrity necessary to establish populations of this species. These findings highlight the importance of preserving the riparian forest to maintain the health of the stream systems. We recommend more studies that focus on the broader geographic and temporal scales to account for factors such as the anthropogenic gradient and historical land use patterns.
