Economics of Land Degradation (ELD) – Riparian Systems Central Asia


Titre : Economics of Land Degradation (ELD) – Riparian Systems Central Asia

Pays : Kazakhstan

Durée : 01/2016 - 12/2016

Contexte  : This particular ELD study was a spin-off of the project Ecosystem conservation and sustainable land use in the Ili-Delta, Balkhash Lake, Kazakhstan, under decreasing water resources. That project was implemented from 2014 to 2016 by University of Greifswald, ICRAF, and Kazakh National University.

Livestock herders from the upstream part of the delta reported during the interview campaign in 2015 that they already suffer from land degradation so that part of the livestock was moved to the downstream villages Jideli, Karoi, and Kuigan, while part of the herders already considered to give up herding. Along with decreasing water inflow from upstream into the Ili Delta, the following changes in the ecosystem services included into this study can be expected : * Provisioning of fodder will be compromised, because the area from which fodder is provided most likely will shrink. Furthermore, the productivity of the ecosystems that provide fodder will decrease. The monetary value at stake was 6.6 million USD per year. * The ecosystem service provisioning of fish (valued 2.7 million USD per year) will decrease, because the spawning space and space for fish to grow up will shrink. * Provisioning of biomass will be compromised, too, because the area of submerged reed will be reduced. The potential of biomass utilization as feedstock for a number of value chains (like fodder or cellulose based materials) was estimated 1.1 to 9.8 million USD annually, depending on investments. * Tourism will be impacted to a minor extent (annual value of 5.8 million USD). The large and expensive tourist bases are located at the major water bodies, which will carry water even if the inflow drops. Smaller tourist bases at the margin of the delta will lose customers when the nearby water bodies fall dry.
