Over time, roads have become an important study object. Several studies were carried out to understand the importance of roads on the hydrogeomorphological dynamics on hillslopes and watershed. Nonetheless, new gaps and new research methods emerged as research progressed on this subject. Therefore, to understand the evolution and new challenges of research on roads, a bibliographic review was prepared based on 300 articles searched in the Scopus platform considering the last two decades (2001–2010 and 2011–2020). We use keywords that refer to roads in the search field, e.g., soil erosion on roads, delivery rate, bank, rails, highways, abandoned roads, and road rehabilitation. The data were tabulated and separated according to the following themes: data collection method, study purposes, road types, and geographic location. Our main conclusions were a) in the 2000s, around 60% of surveys were carried out on unpaved roads and rural roads, mainly in roadbed features; b) In the 2010, occurred a decentralization on the research on rural roads from mainstream countries as US and Australia to Latin American countries e.g., Brazil and Middle East e.g., Iran; c) the studies in emerging countries, mostly tested known research methods in different landscapes of tropical climate; d) a new research perspective in recent decades have emerged, focusing on the influence of roads on the landscape’s dynamics. Finally, roads are recognized as a humanmade landscape signature and studies about nature and biodiversity conservation, particularly at watershed scale, must considered this anthropogenic feature.

No abstract

Este trabalho consiste em avaliar as alterações na paisagem sob os diferentes sistemas de cultivo do tabaco, Sistema de Plantio em Cultivo Mínimo (SPCM), e Sistema de Plantio Convencional (SPC), em uma área localizada na bacia do rio Cachoeira, Rebouças - PR, com ênfase nas dinâmicas e fases de cultivo, manejo e exposição do solo. Quanto à problemática trata-se de uma pesquisa qualitativa, vista que envolve a avaliação de diferentes paisagens, através de uma proposta de análise descritiva, abordando diretamente a paisagem nas diferentes formas de cultivo. Para a consecução da proposta foi realizado pesquisa de campo com avaliação dos componentes da paisagem, durante três fases do calendário agrícola. Os resultados mostram que as diferentes formas de manejo vinculadas a ação antrópica exercida durante o ciclo de cultivo, propiciam na paisagem alterações e posições únicas mediante a cada fase analisada. Desta maneira conclui-se que as dinâmicas de cultivo do tabaco, atribuída às características morfopedológicas, fisicas, econômicas e antrópicas, definem e determinam as relações com o espaço geográfico, atribuindo a paisagem funções e estruturas diferenciadas devido às características produtivas deste tipo de cultivo.ABSTRACTThis work consists of evaluating the changes in the landscape under the different tobacco cultivation systems, Minimum Planting System (SPCM), and Conventional Planting System (SPC), in the area located in the waterfall river basin, Rbouças- PR, with emphasis on the dynamics and phases of cultivation, management and soil exposure. As for the problem, this is a qualitative research, which involves the evaluation of diferente landscapes in the diferente forms of cultivation. To achieve the proposal, field research was carried out with evaluation of landscape componentes during three phases of the calendar. The results obtained consist in presenting that the diferente forms of management linked to the cultivation cycle, allow the landscape changes andu nique positions though each analytical phase. In this way it is concluded that the dynamics of tobacco cultivation, attributed phisical, economic and anthropic characteristics, define and determine the relatons with the geographic space, assigning to the landscape diferente functions and structures due to the characteristics.Keywords: Fumiculture; Landscape; Forms of Cultivation.
