“…Total annual R s levels in our study (113e129 g C m À2 year À1 for NAT and 87e112 g C m À2 year À1 for AFF) were low compared to the range observed by Perez-Quezada et al (2010) in four different land-use types in the Kazakh steppe (288e431 g C m À2 year À1 ). Even higher annual R s were found in a Sitka spruce chronosequence (564e991 g C m À2 year À1 ), being the highest value from the youngest stand (10 years old) and the lowest from the oldest (47 years old) (Saiz et al, 2006).…”

“…Average R 10 values for NAT (0.15e0.53 mmol CO 2 m À2 s À1 ) and AFF (0.12e0.60 mmol CO 2 m À2 s À1 ) (Table 1) were low compared to the values obtained by Perez-Quezada et al (2010) in four land-use types in northern Kazakhstan (1.08e3.64 mmol CO 2 m À2 s À1 ), and by Li et al (2008), who reported values of R 10 of 1.27e2.9 mmol CO 2 m À2 s À1 for three shrubland sites in a mountain area in China. Fitted values of E 0 (K À1 ) showed broad ranges in NAT (67.2e264.6 K À1 ) and AFF (35.8e232.4 K À1 ) ( Table 1) which are similar to the range obtained by Perez-Quezada et al (2010) (58.2e208.9 K À1 ).…”

“…Because deforestation, degradation, and land use change can have direct implications for carbon sequestration and atmospheric carbon dynamics (Perez‐Quezada et al. , Pütz et al. ), the present study is designed to gather reliable information on present trends of carbon release and storage in a SSA old‐growth rainforest ecosystem.…”

“…Perez-Quezada et al 27 provided estimates of 330-360 mm for ET of the grassland steppes, for the growing period from May to October. In a recent review on the role of transpiration (T) in the global hydrological cycle, Schlesinger et al 28 estimated T to comprise 51 AE 15% of total ET for the semi-arid ecosystems thus implying the lesser role of vegetation, in its contribution to ET, in these regions comparative to tropics.…”

The changing water cycle: Burabay National Nature Park, Northern Kazakhstan

et al. 2017

Water resources in Central Asia are scarce, so complicated issues arise from this. Kazakhstan is a Central Asian landlocked country, which has mostly closed drainage basins, characterized by endorheic lakes that do not drain to the oceans. These endorheic lakes are very sensitive to climate change and anthropogenic influences. Very few studies have been conducted on the hydrological cycle of the small endorheic lakes. This work reviews the endorheic lakes within Burabay National Nature Park (BNNP), Northern Kazakhstan. BNNP is a small ecozone consisting of terminal lakes watersheds covered by mixed forests and grasslands. These endorheic lakes have been drying out during the last one hundred years or so with the water level decrease accelerated in the past few decades. According to historical observations , on the one hand precipitation amounts did not significantly change, while on the other hand, air temperature steadily increased. The lake level decrease is most probably caused by a water budget deficit, with evaporation exceeding the precipitation inputs in the long term. The direct anthropogenic impact (water abstraction) plays a minor role in the deterioration of water levels, with most significant impacts through localized land-use changes such as road and building construction in the catchments. The future of the park's sensitive ecosystems in a changing climate is uncertain; therefore, BNNP requires modern ecohydrological monitoring methods and analysis tools to improve our understanding of its hydrological cycle variability, and to enable us to develop adequate adaptation and mitigation measures.
