“…Devendra, 1992; Reddy and Elanchezhian, 2008). Moreover, establishing such a feed source on marginalized croplands, which have become abundant in the irrigated areas of Central Asia (PFU, 2008), could benefit both, rural livelihood and the environment (Lamers et al., 2008; Khamzina et al., 2009).…”

Feed shortages hamper livestock rearing and thus impede the development of rural livelihoods in Central Asia. The production and in vitro quality of foliage from Ulmus pumila, Elaeagnus angustifolia and Populus euphratica on degraded cropland were examined to determine the potential of these species to supplement diary cattle diets. Leaf dry matter (DM) production of the species, respectively, averaged 6, 8 and 17 t DM/ha, 4 years after planting. Over seasons and years, crude protein concentrations (g/kg DM) ranged within 151-257 for E. angustifolia, 70-241 for U. pumila and 92-187 for P. euphratica. The metabolizable energy concentrations (MJ/kg DM) were the highest in U. pumila and ranged within 9-10, followed by 7-10 of E. angustifolia and 7-9 of P. euphratica. The organic matter digestibility (%) ranged within 58-70, 54-66, and 51-66, respectively, for these species. These indicators combined denoted a medium-to-good feed quality of E. angustifolia and U. pumila leaves as a cheap protein supplement to roughages. The foliage of P. euphratica was the least suitable. The seasonal profile of in vitro indicators revealed the highest feed quality in spring but early fall seems most appropriate for forage collection given the peak leaf production and an adequate quality.

“…In Khorezm, due to a lack of pastures, livestock feeding is based mainly on nutrient-rich but expensive crop byproducts. Tree foliage is not marketed, therefore, as suggested by Lamers et al (2008), the prices of the leaves of the selected tree species were calculated based on the foliar crude protein content compared to that of marketed dry alfalfa hay. The derived price was 53.3 USD/t for E. angustifolia, 32.7 USD/t for P. euphratica and 38.8 USD/t for U. pumila leaves.…”

“…Afforestation as an alternative use of degraded croplands in the irrigated areas of Uzbekistan can increase the productive capacity of the land via the provisioning of tree products for income generation Lamers et al, 2008). For instance, the rural population has a high interest in fuelwood as a means to reduce their reliance on gas, which is presently the main source of energy.…”

This study analyzed the financial attractiveness of Clean Development Mechanism Afforestation and Reforestation (CDM A/R) in irrigated agricultural settings. The Net Present Value (NPV) and Internal Rate of Return (IRR) of CDM A/R were estimated by analyzing the case of Khorezm region in Uzbekistan, where a mixedspecies tree plantation was established on marginal cropland. The dual purposes of carbon sequestration and production of fruits, leaves as fodder, and fuelwood were studied over a seven-year rotation period. We compared the opportunity costs of land in marginal agricultural areas between this short-rotation plantation forestry and the annual cultivation of the major crops in the region, i.e., cotton, winter wheat, rice, and maize. The analyses were performed considering different levels of irrigation water availability, from 0 to 30,000 m 3 /ha, to reflect the reality of a high variability of water supply in the region. The NPV of CDM A/R ranged between 724 and 5794 USD/ha over seven years, depending on the tree species. Among the latter, Elaeagnus angustifolia L. had the highest profits due to the annually recurring cash flows generated from fruit production. Temporary Certified Emission Reductions (tCER) ranged within 399-702 USD/ha after the assumed 7-year crediting period and would not suffice to cover initial investments and management costs of tree plantations. IRR peaked at 65% with E. angustifolia under the conventional afforestation and measured −10% and 61% when considering only the tCER and the CDM A/R, respectively. In contrast, other species had higher IRRs in case of the CDM A/R. The total profits from tree plantations exceeded those of both cotton and winter wheat, even with the assumption that there was an optimal irrigation supply for these crops. Rice production was overall the most profitable land use option but required water input of 26,500 m 3 /ha/year, which is not consistently available for marginal croplands. We argue that the current global average price of 4.76 USD/tCER is insufficient to initiate forestrybased CDM projects but, in the absence of other incentives, can still motivate forestation of degraded croplands for land rehabilitation and the provisioning of non-timber products. Given the low irrigation needs of trees, 3-30% of the crop water demand, a conversion of degraded cropland to forested areas could save up to 15,300 m 3 /ha/year at the current tCER price. Combining the monetary value of water and carbon would enlarge the scope for CDM A/R in irrigated drylands, thus enhancing the investments in marginal land rehabilitation and strengthening the resilience of rural populations to the repercussions of climate change.

“…Small-scale, multipurpose tree plantations are a recognized means to convert degraded, salt-affected croplands in arid Uzbekistan, Central Asia, into productive areas (Khamzina et al, 2006Lamers et al, 2005Lamers et al, , 2008 ). Such a land use change towards increased productivity also has the potential to reduce total greenhouse gas emissions of N 2 O and CH 4 since fluxes from perennial systems are substantially lower than from annual cropping systems such as cotton, wheat, and rice (Scheer et al, 2008).…”
