Land use change affects the biodiversity of terrestrial landscapes as well as of the freshwater systems they surround, and thereby numerous ecosystem services that are essential for human well-being. Previous research suggests that freshwater systems show delayed responses to abrupt disturbances such as deforestation, however less is known about whether there is a legacy effect of landscape history on freshwater communities under a long history of land use change. We addressed this research gap here by first quantifying the historical complexity of landscapes, including natural and agricultural formations, in terms of their composition and configuration in 26 tropical catchment areas surrounding 101 streams over a 30-year period. We identified clear evidence for a memory effect of past events, whereby historical landscape complexity, measured as the information entropy of landscape composition, positively affected freshwater biodiversity. Finally, using a causal discovery approach, we showed that species richness was causally related to landscape complexity only when historical values were incorporated. Our results corroborate previous work on the positive effect of landscape complexity on biodiversity, and also confirm the role of historical contingencies in predicting future ecological outcomes.

The article explores methods of estimating discount rate for investment projects financed with budgetary funds and aimed at creating social benefits. Social benefits often do not have a direct monetary value, so the methods for determining the discount rate for such projects differ from market ones. Spending budget funds on investment projects means that society gives up consumption at the current moment in time for the sake of future return on investment. The discount rate should reflect public preferences regarding the distribution of consumption between the current and future periods. The method for estimating these preferences is called the social rate of time preferences. Another approach to determine the discount rate allows one to consider the alternative possibility of implementing a project in the private sector (social opportunity cost of capital). The article describes the development of methods for evaluating the social discount rate and discusses the possibilities of their application for Russia. The value of the social rate of time preferences, equal to 2.5%, and the value of the social opportunity cost of capital, equal to 4.4—5%, are substantiated for short-and medium-term public investment projects in Russia. Rates are given in real terms.
