Tallo Urban Village which is one of the villages in Tallo District with a high population density, Tallo Urban Village has conditions that are categorized as slums on water based on Makassar Mayor Decree No.050.05 / 1341 / KEP / IX / 2014. There are 6 Subdistricts in Makassar City that are designated as slums especially Tallo Urban Village so that the problem in this study can be formulated regarding various factors that led to the development of slums in Tallo Urban District of Makassar. The purpose of this study is to identify the cause of the development of slums in Tallo Urban Village, Makassar City. In this study, the slums are characterized by physical areas (building management, water supply, wastewater management, drainage facilities, and environmental roads), non-physical areas (ownership of land rights, population density). The research variables we use in this study are Slums; Population density; Width of the Road Environment; Drainage Conditions; Waste Water Management; Clean water supply; Building Layout; and Building Status. In this study, the data collection techniques used were Multi-Stage Sampling, namely: area sampling technique; proportional sampling technique; and simple random sampling. The analytical approach used in this research is to use a quantitative approach, using the Chi-Square method. The results of this study found that the cause of the development of slums in the Tallo District of Makassar City was population growth that continued to increase each year. This shows that the allotment of land functions in Tallo Kelurahan, besides functioning as a settlement function, many also function as warehousing, so that Tallo Kelurahan is classified as moderate density, with population growth increasing every year

Organic Fruit

Worldwide research goals and concerns are to soil conservation and improve. This conception is mostly actual in horticulture where the numbers of high-density plantings are continuously increasing. High-density orchards cause more intensive nutrient and water uptake. So that the preservation of soil moisture and nutrient level are key factors in qualified fruit growing. On the other hand due to the climatic changes the water supply of trees will be satisfied among worse conditions than some decades ago. Appearance of water supply problems and water stress is increased in organic growing, where the number of corrections is limited anyway. Furthermore, floor management is a successful tool in weed management which causes many problems for organic growers due to the prohibition of synthetic herbicides. This paper will mainly focus on the nutritional aspects of methods of orchard floor management for growers adopting organic fruit management to make their production profitable.

<p>Since the beginning of humanity, geomorphological diversity and relief features some territories, have influenced human settlement and population density. Certainly, the more comfortable conditions of the relief caused the increasing population of the some territory. Thus, there was more intensive settlement on fluvial or marine forms of relief, while on karst, aeolian relief, landslides and areas of escarpment, human settlement was less or completely absent. The only exception is the times of wars, occupations or other disasters, when people settled in unfavorable relief areas (karst, deserts, etc.). The following elements of the relief influenced the construction of residential buildings as well as the industrial activity: the slope of the hillside, surface sunshine, surface geodynamics, water supply, horizontal and vertical terrain distribution, hypsometric features, relief energy. In the paper, the evaluation of individual elements will be presented on examples from the Republic of Serbia and the Republic of Montenegro.</p>

We evaluated the hypothesis that the modified population density of Aquilegia formosa Fisch. ex DC. (Ranunculaceae) resulting from the introduction of Sitka black-tailed deer ( Odocoileus hemionus sitkensis ) in the Haida Gwaii archipelago affects the pollination and reproductive performance of this herbaceous species. We compared the population density, pollination, and reproductive success of A. formosa among three small islands colonized by deer and three deer-free islands. Islands with deer had a substantially lower absolute density and a greater relative density of A. formosa than deer-free islands. The presence of deer was associated with higher pollen deposition, which probably resulted from the greater relative density of A. formosa on islands with deer. However, the presence of deer had no significant effect on individual reproductive success. The latter result is likely a consequence of the lack of pollen limitation in this species, as well as of the conflicting relationship between the absolute and relative densities of A. formosa and the presence of deer.
