Ecologia de cultivos: caracterização dos aspectos ecológicos dos diferentes cultivos no município de Cristais Paulistas-SP

Planning is an essential instrument for the agricultural occupation of the lands, because it supports the activities of food production and raw materials. It must be driven by techniques that provide the sustainability of these activities, so that also ensures the environmental balance of agroecosystems. Lands misuse can be considered as one of the causes of frustration of agricultural activities. Thus, the occurrence of discrepancies between the effective use (real use) of the land and its agricultural aptitude can compete, in many cases, to the decrease of productivity, as well as for soil degradation. In this way, this research intends to study the relationship between the temporary cultivations, halfperennial cultures, perennial and its developmental environment, determining the edaphoclimatic characteristics of landscapes. From then on, a letter shall be subject to the use and occupation of the soil for agriculture in the municipality of Cristais Paulista-SP, aiming to describe the spatial organization of land use and vegetation cover, and emphasizing management and conservative practices. For that, climatic factors were characterized, fundamentally humidity, temperature and luminosity; edaphics, including parental material, chemical and physical properties, fertility, soil temperature and climatic zoning; biotic, referring to the suitability of different cultures or to be implanted; physical, such as geomorphology, slope, geology, hypsometry and hydrology; socioeconomic, in particular production and marketing seasons; and the way they all, together, affect the adaptation, distribution and production of crops. Using this information, the zoning of the area of study was done based on the 21 nominated groups obtained, in addition to recommendations and suggestions for handling each type of cultivation...

Mapeamento geológico-geomorfológico na região de Quirinópolis-GO

Geological and geomorphological mapping is an important tool for the characterization of physical environment, thus enabling the planning and use of areas more efficiently. This work represents a geological- geomorphologic mapping on the scale of 1:20.000 in the rural area of Quirinópolis – GO town, where outcrop rocks of Paraná Sedimentary Basin, specifically the Bauru Group. Through the methodology of analysis of integrated elements of the physical environment, it was possible to delineate geological- geomorphological five units, which were characterized as lithology, topography, soil conditions, and operating processes, and the development of weathering profiles bring of great importance for planning of land use as occupation thus avoiding further degradation of the physical environment

O clima urbano em Alfredo Marcondes/SP: uma análise dos indicadores geoambientais

There are obvious changes that occur within the cities, experienced in synthesis for the degradation of the environment and especially the worsening quality of life. Even small cities, began to exhibit characteristics typical of an atmospheric climate. Thus, it becomes natural to analyze the characteristics of these spaces, unlike the medium and large cities, provide a detailed analysis of the peculiarities of intra-urban space in order to highlight what factors enhance or soften the formations of a typical urban climate distinct patterns of land use. The aim of this research from a geoenvironmental mapping of attributes (uses and land cover, vegetation and tree characteristics of buildings) while representing the dynamic City entertainment. Thus, we seek to inter-relate these indicators to analysis climate urban-rural and intra-urban applied to the city of Alfredo Marcondes / SP, a small town in order to identify a potential compromise climate conditions point to generate a specific climate. From this detailed analysis, we intend to give suggestions with the government to improve the comfort of that environment. For the data collection was organized a specific methodology for its collection, organization and representation and for the record of climatic data (temperature, wind speed and direction and cloud cover) were used mini-shelters weather with temperature sensors in fixed locations, and a temperature sensor attached on the side of a vehicle, 1.5 meters in height from the floor for 42 points perpassando selected in different intra-urban spaces...

Desempenho e uso eficiente da terra de modalidades de consorciação com milho e forrageiras

This study was developed with the aim of evaluating the performance and land use efficiency of different arrangements of intercropping with maize and forage. The field experiment was conducted in Tangar da Serra/MT. The experimental design was a randomized block in factorial scheme 3x2 + 1, were as three arrangements of intercropping, two species of forage and an additional treatment with maize monoculture in four replication. In maize monoculture and intercropping were evaluated: plant height and ear insertion height, plant population, weight of 100 grains, productivity, number of grain rows and number of grain per row. In forages intercropping with maize were evaluated plant population and dry matter accumulation. The arrangements with Maize + Forage sown in the line and Maize + Forage sown in two rows between rows with the species Urochloa hybrid promoted best corn yields. The modality and species affect both the productivity of maize as forages species. Grain yield of maize is higher in monoculture. The higher dry matter accumulation of Urochloa hybrid occurs in the Maize + Forage sown in one row between rows, while, for the Urochloa brizantha the arrangements studied do not affect their yields. The arrangement with best land use efficiency is Maize + Forage sown in two rows between rows for both study forage species.

Potential use of polyacrylamide for soil erosion control in Brazil

Since soil erosion is currently a worldwide threat, its control has become a necessity. The performance and effectiveness of synthetic organic polymers such polyacrylamide (PAM), have been intensively studied, especially for erosion control in temperate climate conditions. In tropical regions, however, where climatic conditions are usually severe, very little research has been conducted. The Brazilian region is a good example, where few papers on this subject exist. In addition to the severe climatic conditions, careless land use has been prevalent for many years. The use of PAM for erosion control in Brazilian soils may be a good option to minimize the impacts of the soil degradation process, but more research is required to optimize its application.

Geoprocessamento aplicado na determinação das áreas de preservação permanente e áreas de conflito com cultivo agrícola no município de Lençóis Paulista/SP

The city of Lençóis Paulista has a great part of its agricultural land cultivated by sugar cane and reforestation of eucalyptus and pine trees. In the county there are industries that exploit energy extracted from energy cogeneration. The city of Lençóis Paulista, in recent years, has been demonstrating considerable levels of economic and social growth with the industries that are working with sugarcane and eucalyptus mainly responsible. However, the expansion of agricultural land in many cases does not take into consideration the permanent preservation areas that are protected by the law. The APP's are of fundamental importance in the management and conservation of the environment preserving the natural plants and wildlife, and also preventing erosion and the silting of drainage networks. This objective of this study was to diagnose land use, analyze if Permanent Preservation Areas are regulated to the Brazilian Forestry Code (1965) and also diagnose areas of conflict. In relation to the use and occupation of land, the research has shown how the land is divided (agricultural crops and urban zones), and highlighted areas of conflict with the Permanent Preservation Areas. All of the information is contained in maps using Geographic Information Systems. However, it has become clear that environmental laws are not respected as much in urban areas as they are in rural areas. The PPA's are virtually nonexistent, thus creating damage to the environment and local population.

Ocupação do solo em nove sub-bacias incluídas na bacia hidrográfica do Ribeirão do Faxinal - Botucatu (SP)

Expansion of agricultural practice, cattle raising and forestry, in a disorderly way and no limits of land use, generates the degradation of natural resources such as soil, water and vegetation. That fact brings consequences, impacts the environment and the rural landscape. This study aimed to identify and quantify the land use in nine watersheds included in the watershed of Faxinal creek, located in western Botucatu, São Paulo State, Brazil, at 22º 51’ 35” and 22º 57’ 02” – Latitude S and 48º 39’ 42” and 48º 38’ 01” – Longitude W. The basin was subdivided into 9 subunits, being eight from second and one from third-order branch. The diagnosis of the subunits was carried out with geospatial technologies, in order to gather data on the use and occupation of the soil. Based on the obtained results, was concluded that the sub watersheds are occupied by the sum of areas of Citrus, horticulture, coffee plantation and small other occupations (25,81%), followed by reforestation (24,80%), as an isolated occupation element, has occupied the largest area.

Áreas de preservação permanente (APP) na sub-bacia hidrográfica do córrego do Marimbondo, Jales (SP): um estudo das condições ambientais

This work aimed to carry out a study of the environmental conditions of the Permanent Preservation Areas (PPAs) in the sub-basin of Marimbondo Stream in the city of Jales (SP), through remote sensing techniques and taking as the basis Brazilian environmental legislation, the Forest Code Federal Law Nº 12,651/2012. Permanent Preservation Areas are inserted intrinsically improved conditions in the quantity and quality of water in the areas of springs and along water bodies in rural properties. Therefore, we also carried out studies on the new Forest Code compared to the old Federal Law Order no. 4771/1965 and the observation of its application in the area of sub-basin as well as carrying out the simulation. The results of this research allowed toverify the need for direct implementation of the monitoring measures with the Forest Code, and this water management tool in Brazil, which will ensure sustainable management practices of land use and land cover, with direct benefits to water production, mainly for public supply. Also there was a greater need for involvement by the public actors, the Basin Committee of the São José dos Dourados and the municipal government of Jales, in order to truly act aimed at the protection and maintenance of the water body Stream Wasp
