Digital technology helps to visualize the natural potentiality of the landscapes that exist on the earthly surface. Indeed, information is more significant with fieldwork. The interpretation of the images through the application of the image segmentation function, available in the SPRING 5.5.5 software, granted the understanding of natural landscapes in the Pacoti River Watershed, precisely in the Baturité Residual Massif. Thus, geoprocessing may act as a mitigating tool in nature conservation since this tool reveals the diversity in nature and its uses.

The Relationship

Com o objetivo de ponderar conexões entre quadros naturais e a ocupação humana pré-colonial, caracterizou-se os artefatos e a contextualização geomorfológica e ambiental de quatro sítios líticos vinculados a antigos registros de grupos caçadores-coletores do sul e sudeste do Brasil, associados a três distintas indústrias líticas. Elencou-se associação dos sítios com terrenos de baixos declives e altimetrias em seus respectivos contextos (terrenos mais estáveis para fixação humana), adjacentes a córregos e próximos de faixas do terreno que registram maiores inclinações e desníveis verticais, mais propensas a apresentarem afloramentos rochosos (fontes potenciais de matérias-primas para a confecção de ferramentas lascadas). Elencou-se fontes de matérias-primas nos entornos de cada sítio e as matérias-primas associadas aos artefatos, e ponderou-se a correlação entre os dois conjuntos de dados. Analisou-se a relação dos padrões tecnológicos de artefatos líticos com a caracterização petrográfica das matérias-primas, verificando-se quais silcretes semelhantes foram usadas para produção de artefatos distintos. Ainda, verificou-se que alguns dos produtos líticos de um dos sítios analisados mostram padrões tecnológicos semelhantes, mesmo quando obtidos a partir de silcretes distintos. Caracterizou-se ausência de variação significativa dos atributos tecnológicos dos artefatos registrados em diferentes posicionamentos verticais nos perfis das unidades de escavação nas quais foram registrados, mesmo quando mostram-se associados a registros paleoambientais distintos (alternâncias entre climas mais secos que os atuais e condições caracterizadas por incrementos de umidade no intervalo de 11 a 7 mil anos atrás).Palavras chave: sítios arqueológicos líticos; Holoceno Inicial, paleoclimas, ameríndios, geoarqueologia The ancient human occupation (11-7 thousand years ago) of the Southern Brazilian Plateau: geomorphological, geological, paleoenvironmental and technological characterization of archaeological sites related to three distinct lithic industries A B S T R A C T In order to discuss connections between the natural landscapes and pre-colonial human occupation, were characterized the artifacts and the geomorphological and environmental contextualization of four lithic sites linked to ancient records of hunter-gatherer groups from the south and southeast of Brazil, associated with three distinct lithic industries. The association of sites with low slopes and altimetry in their respective contexts (more stable terrains for human settlement), adjacent to rivers and close to terrains that register greater inclinations and vertical unevenness, more likely to present rocky outcrops (potential sources of raw materials for making chipped tools) was listed. Were characterized sources of raw materials in the surroundings of each site, the raw materials associated with the artifacts, and the correlation between the two data sets was considered. The relationship between the technological standards of lithic artifacts and the petrographic characterization of the raw materials was analyzed, verifying which similar raw materials were used to produce different artifacts. Also, it was found that some of the lithic products from one of the analyzed sites show similar technological patterns, even when obtained from different raw materials. There was a lack of significant variation in the technological attributes of the artifacts recorded in different vertical positions in the profiles of the excavation units in which they were recorded, even when they are associated with different paleoenvironmental records (alternations between drier climates than current and others characterized by increments in the moisture between 11 to 7 thousand years ago).Keywords: lithic archaeological sites; Initial Holocene, paleoclimates, amerindians, geoarchaeology

On Farm

The study of nutritional properties in landrace products and the general context of its cultivation site are crucial to designing a sustainable on-farm strategy for landrace conservation. The present study describes the main nutritional aspects of two Brassica rapa subspecies rapa landraces collected in Puglia, Italy along with agroecological and socioeconomical traits where they are cultivated. The two B. rapa landraces (‘Cima di rapa dalla testa’ and ‘Cima di rapa antica’) are only found in sites at 700–800 m asl and in two landscape units (the Southern Daunian Mountains (SDM) and the Umbra Forest (UF), respectively) of the Foggia province. These rare landraces were selected by farmers to produce turnip greens/tops from ancient root turnip crops. They are named and consumed by local people in the same way as turnip tops of Brassica rapa subspecies sylvestris (‘Cima di rapa’), which are widely cultivated in Puglia. Compared to the most common ‘Cima di rapa’, the two highlighted landraces have a better nutritional profile linked to an improved content in antioxidant compounds—i.e., vitamin C (458 mg kg−1 FW), total phenols (347 mg ac. gallic equivalent kg−1 FW)—in glucosinolate (741 µmol kg FW−1, in ‘Cima di rapa antica’) and in minerals, such as K. Both landraces are deemed as having a high risk of erosion. Few exemplars are cultivated in marginal lands and urban/peri-urban areas (SDM), or in isolated sites within the UF, which is a special protection zone within Gargano National Park. However, natural, cultural, and recreational tourism are the main economic activities in both landscape units.

Geomorphological Analysis

In the present study, an attempt has been made to study the quantitative geomorphological analysis and hydrological characterization of 95 micro-watersheds (MWS) of Baira river watershed in Himachal Pradesh, India with an area of 425.25 Km2. First time in the world, total 173 morphometric parameters have been generated in a single watershed using satellite remote sensing data (i.e. IRS-P6 ResourceSAT-1 LISS-III, LandSAT-7 ETM+, and LandSAT-8 PAN & OLI merge data), digital elevation models (i.e. IRS-P5 CartoSAT-1 DEM, ASTER DEM data), and soI topographical maps of 1: 50,000 scale. The ninety-five micro-watersheds (MWS) of Baira river watershed have been prioritized through the morphometric analysis of different morphometric parameters (i.e. drainage network, basin geometry, drainage texture analysis, and relief characterizes ). The study has concurrently established the importance of geomorphometry as well as the utility of remote sensing and GIS technology for hydrological characterization of the watershed and there for better resource and environmental managements.

Reasons to travel and to visit concrete destinations in the Czech Republic are especially the nature and cultural/historical sightseeing. The presented paper specializes on the first reason and it studies the specific landscape features together with the primary tourism potentials. It focuses on the protected landscape area of Kokořínsko, which is divided into 6 landscape units according to their landscape character. In these landscape units, the authors study the primary tourism potential and the elements of natural, cultural-historical and aesthetical characterization of landscape. The relation between the tourism potential and the landscape features is measured by the Spearman´s coefficient. Moreover, the expert's evaluation of landscape characteristics is confronted with the the landscape perception of tourists which were questioned in the PLA Kokořínsko.
