“…Higher runoff volumes were observed on slope B (Figure 3), where the first growth stages of sugarcane coincided with the rainy season (Figure 4 -Supplemental material). According to Silva et al (2016), during these initial growth stages, the leaf area index (LAI) is still low (< 1 m 2 m -2 ), increasing to 3 m 2 m -2 in the third growth stage. On the other hand, the LAI of the riparian forest (4 to 5 m 2 m -2 ) was constant during the entire year (Silva et al, 2016).…”

Soil erosion leads to land degradation and translocation of soil particles together with associated particulate organic carbon (POC) and nutrients, thereby influencing the global carbon cycle. In the present study, we estimated the contribution of POC delivered to a first-order stream from upslope sugarcane fields and a riparian forest in southeast Brazil. The results show that the amount of surface runoff and soil erosion generated in the riparian forest is significantly lower than in the upslope sugarcane field. However, the contribution of the forest to the total stream bed POC was above 70%, even though most sediments delivered to the stream originated from the upland sugarcane fields. The discrepancy between sediment and POC delivery from 2 both land uses is a consequence of the presence of preferential runoff pathways from the agricultural fields, through the buffer strips, to the stream. This disconnection between the main sources of sediment and POC to the first-order stream is a potentially important mechanism influencing the transfer of POC from upslope areas to waterways. This mechanism should be considered in order to more reliably assess fluxes of OC from upslope areas to first-order streams in landscapes where arable land is separated from streams by a semi-natural buffer zone with permanent vegetation.

“…Selain dari kondisi iklim lokal dan jenis tanaman tebu, hasil tebu sangat dipengaruhi oleh kondisi hidrologi lahan pertanamanan (Osorio et al, 2014). Ketersediaan air tanaman yang digunakan untuk fase pertumbuhan dan perkembangan tanaman tebu, tidak hanya dipengaruhi oleh jumlah curah hujan yang terjadi, tetapi juga kondisi kanopi tanaman dalam kemampuannya untuk menahan air hujan (Fernandes et al, 2017;Silva et al, 2016). Berdasarkan diagram forrester neraca air tanaman (Handoko, 2005) yang disajikan pada Gambar 1, indeks kanopi tanaman (LAI) akan mempengaruhi nilai intersepsi air hujan (Ic), dan transpirasi aktual (Ta).…”

Sugarcane productivity is naturally affected by climate variables and limited by the water availability. This study simulated a water balance model to estimate sugarcane water requirement and to estimate the best planting time as well based on its optimum productivity in Kediri Regency. Water requirement was estimated by water loss of evapotranspiration following FAO No. 24, while the productivity was based on mid-maturing sugarcane growth and development. Sugarcane rainfed area in Kediri Regency needs approximately 26-128 mm water per month based on its loss by evapotranspiration. The value varied due to the growth phase. More than 60% water was used in vegetative phase for developing buds and stem elongation of about 3-9 months after planting. The highest sugarcane productivity was obtained in July-September as the best planting time shown by simulation. Moreover, water deficiency during mid-season of sugarcane growth could decrease productivity by a significant amount. The work presented here could be used as a tool to help decision makers for irrigation management and select the best planting date.

“…Removal of dense tropical forests for the implementation of agriculture may lead to deep modifications in the dominant hydrological processes (Bruijnzeel et al, 2005). Some of the most notable direct impacts are changes in interception rates (e.g., Fernandes et al, 2017;Salemi et al, 2013;Silva et al, 2016) and decreases in evapotranspiration rates, which generally lead to increases in average streamflow (Bruijnzeel, 2004). Other impacts frequently cited are increases in groundwater recharge, base flow, and low flow conditions (Andréassian, 2004).…”

The replacement of natural forests with agriculture is generally associated with modifications in the hydrological behavior of a basin. This is particularly notable in the tropics and subtropics. Southern Brazil is a region with extensive agricultural production, forest conservation, and a vast unexplored streamflow data despite substantial rainfall trends observed in recent decades. In this work, we explore trends in the streamflow regime in the majority of the monitored basins in Southern Brazil. Additionally, we evaluate if pristine forested basins and agricultural nonforested basins have significantly different streamflow responses to changes in rainfall. We analyzed annual averages, maxima, minima, and seasonality of a 36‐year data set (1975–2010) of 675 rainfall and 140 streamflow gauges. Results reveal that large trends are widespread in Southern Brazil, especially in basins with areas smaller than 10,000 km2. Changes in the rainfall regime did not directly translate into changes in the streamflow regime. Changes in the annual maximum flow of forested basins were not statistically significant even when the annual average and maximum rainfall increased significantly. Correlations between changes in rainfall and streamflow for two indices, namely, duration of low‐magnitude events and seasonality, were statistically significant (p < 0.05) only for agricultural basins. The results indicate a higher propagation of hydrological changes through anthropogenically modified systems, providing evidence that agricultural basins are more sensitive to changes in the rainfall regime.
