title: 'swcEcon: Economic Analysis of Soil and Water Conservation Measures in Watersheds'
version: 0.1.0
doi: 10.32614/CRAN.package.swcEcon
abstract: 'Provides functions and benchmark datasets for the economic appraisal of
  soil and water conservation (SWC) measures in watershed development projects. Implements
  benefit-cost ratio (BCR), net present value (NPV), internal rate of return (IRR)
  via the bisection method of Brent (1973, ISBN:9780130223715), modified BCR, marginal
  rate of return using the CIMMYT (1988, ISBN:9686127127) method, payback period,
  soil loss economic valuation via the Universal Soil Loss Equation of Wischmeier
  and Smith (1978, ISBN:0160016258), groundwater recharge valuation, employment generation
  ratio, sensitivity analysis, switching value analysis, and Monte Carlo simulation.
  Six datasets are included: state-wise BCR benchmarks from NABARD (2019) watershed
  evaluations, USLE erodibility parameters for Indian soil orders from NBSS and LUP,
  rainfall erosivity for twenty Indian districts from IMD data, SWC unit cost norms
  from PMKSY-WDC (GoI 2015), and two hypothetical datasets for illustration. Methods
  follow Gittinger (1982, ISBN:9780801825439) and Squire and van der Tak (1975, ISBN:9780801816697).'
