Natural resource management in agriculture: methods for assessing economic and environmental impacts.

Book cover for Natural resource management in agriculture: methods for assessing economic and environmental impacts.


This book examines methodological difficulties and presents practical methods that can be used in the assessment of the economic and environmental impacts of natural resource management (NRM) in agriculture. Following an introduction, part II (chapters 2-5) examines the valuation of ecosystem services and the measurement of biophysical indicators of NRM impacts. Part III (chapters 6-8) introduces ...


Chapter 9 (Page no: 199)

Valuing soil fertility change: selected methods and case studies.

This chapter examines the significant challenges in assessing, i.e. quantifying and valuing, the impacts of soil fertility and nutrient depletion. After briefly reviewing the main economic approaches that are used to value soil nutrient change, four case studies are presented. These illustrate the use and limitations of the two valuation approaches most commonly applied in developing country analysis: the replacement cost approach (RCA) and the change in productivity approach (PCA). The first case study from Ghana assesses the private costs, experienced by farmers, of soil nutrient depletion in two different farming systems. Focusing on nutrient gains from wastewater irrigation in Mexico, the second case demonstrates the divergence of perspectives between local farmers and regional communities on the value of additional nutrient supply. The third case highlights the economic cost of nutrient depletion in sub-Saharan Africa. While the first three cases use the RCA to assess soil fertility change, the final case, from India, uses the PCA to examine erosion as a nutrient depleting process.
