“…Moreover, lower soil moisture was observed as distance from the center of F. albida trunk decreased in the AE land use system, possibly because of negative effects of Eucalyptus on moisture availability for crops growing close to the tree (Sanginga and Swift 1992). Other studies in Ethiopia indicated decreasing crop output because of the negative hydrological impacts of Eucalyptus trees growing close to crops (Malik and Sharma 1990;Saxena 1991;Calder et al 1993). Apparently, our choice of systems, with F. albida and E. camaldulensis growing in mixed stands dampened negative effects of pure E.…”

Implications of changes in traditional Faidherbia albida based land use systems on productivity were investigated in Tigray, northern Ethiopia. The relation between F. albida based-land use systems and crop productivity was explored in 77 fields and 81 farms at field and regional scales, respectively. Barley yield and soil fertility increased when field locations were closer to a F. albida trunk in the F. albida alone (AA) and F. albida + livestock (AL) land use systems. However, the F. albida + Eucalyptus camaldulensis (AE) land use system showed a decreasing trend in barley yield and soil fertility as distance from a F. albida trunk decreased. At regional scales, higher F. albida tree density per farm and sparsely cultivated land use types were associated with increased potential ecosystem services (barley yield). This study suggests that local biodiversity components (e.g. F. albida trees) can increase crop yield and soil fertility significantly when grown within and around farm lands. This study contributes to the knowledge on agricultural productivity enhancement by developing an approach to scaling up from farm to regional level.

“…Field surveys within the TG Halli catchment indicate a significant increase in eucalyptus plantation area in the past 40 years. Several studies have documented that eucalyptus plantations create unsaturated conditions over a deep root zone and can thus reduce subsurface contributions to streamflow (Calder et al, 1993;Farley et al, 2005). …”

“…First, the plantations could not themselves have led to groundwater mining (as has been claimed in other parts of Karnataka (Calder et al, 1993)), because shallow groundwater in the region had largely disappeared by time eucalyptus plantations were promoted under the social forestry programme in the early 1980s. Second, we assumed that eucalyptus transpires at a rate of 830 mm yr −1 (the annual average rainfall).…”

Abstract. Water planning decisions are only as good as our ability to explain historical trends and make reasonable predictions of future water availability. But predicting water availability can be a challenge in rapidly growing regions, where human modifications of land and waterscapes are changing the hydrologic system. Yet, many regions of the world lack the long-term hydrologic monitoring records needed to understand past changes and predict future trends.We investigated this "predictions under change" problem in the data-scarce Thippagondanahalli (TG Halli) catchment of the Arkavathy sub-basin in southern India. Inflows into TG Halli reservoir have declined sharply since the 1970s. The causes of the drying are poorly understood, resulting in misdirected or counter-productive management responses.Five plausible hypotheses that could explain the decline were tested using data from field surveys and secondary sources: (1) changes in rainfall amount, seasonality and intensity; (2) increases in temperature; (3) groundwater extraction; (4) expansion of eucalyptus plantations; and (5) fragmentation of the river channel. Our results suggest that groundwater pumping, expansion of eucalyptus plantations and, to a lesser extent, channel fragmentation are much more likely to have caused the decline in surface flows in the TG Halli catchment than changing climate.The multiple-hypothesis approach presents a systematic way to quantify the relative contributions of proximate anthropogenic and climate drivers to hydrological change. The approach not only makes a meaningful contribution to the policy debate but also helps prioritize and design future research. The approach is a first step to conducting use-inspired socio-hydrologic research in a watershed.

These studies have generally shown that afforestation of grasslands have reduced streamflows due to increased evaporation of rainfall intercepted by the forest canopy.…”

Abstract:Uruguay has encouraged the development of the forestry sector since 1989. As a member of the Montreal Process, the country has followed a set of criteria and indicators for the Sustainable Forest Management. The aim of this paper is to describe the studies carried out in a large basin of 2097 km 2 , located in an area of humid subtropical climate and 1300 mm of long-term mean annual rainfall, where the conversion of natural grasslands to forests increased up to 540 km 2 during the last 15 years. Using data from daily rainfall and streamflow, the study analyses the effects of afforestation on the runoff and water loss. The analysis comprises hydrographs resulting from comparable rainfall events and annual and seasonal streamflow and water loss behaviour, both before afforestation (1975)(1976)(1977)(1978)(1979)(1980)(1981)(1982)(1983)(1984)(1985)(1986)(1987)(1988)(1989)(1990)(1991)(1992)(1993) and during the afforestation period (1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008). A statistically significant reduction of runoff volumes (33-43%) and peak flows (59-65%) were identified on storm hydrographs. The annual and seasonal streamflow also showed diminishing tendencies due to the forestry development, whereas the water loss increases. The annual streamflow decreased between 8Ð2 and 36Ð5% depending on the annual rainfall totals. The streamflow reduction was higher during spring and summer (25Ð2-38Ð4%) and smaller during autumn and winter (15-20Ð3%). The water loss is expected to increase by 98 mm for the long-term mean annual rainfall. The resulting information is a valuable input for the Integrated Water Resources Management of the Negro river basin located downstream, where hydroelectric power, rice irrigation and forestry development are supported.
