title: Tree Shelterbelts as an Element to Improve Water Resource Management in Central Asia

description: This dataset was moved to: https://doi.org/10.34725/DVN/0KKJ09In Central Asia, agriculture, notably irrigated agriculture, is the largest water consumer. Currently, flood and furrow irrigation are the dominant irrigation methods in Central Asia, in particular in the post-Soviet countries. Against the background of current and increasing competition for water—e.g., through reduced river runoffs in the course of climate change—water consumption of agriculture needs to be reduced. On the field plot level, improved irrigation technologies, like dripi rrigation or plastic mulch, can reduce water consumption substantially. Alternatively, tree lines as wind breaks (shelterbelts) also can reduce crop water consumption, as shown by research from many drylands around the world. As previous research has concentrated on crop water consumption and not on tree water consumption, this paper brings the two together, in order to approach a more holistic picture, in how far shelterbelt systems, including the trees, may have the potential to save water or not. Crop water consumption was assessed through the Penman–Monteith approach for corn, wheat, potato, barley, and pear under open field conditions and under an assumed influence of a tree shelterbelt. Tree water consumption was investigated through sap flow measurements. Crop water consumption was reduced by 10–12% under influence of a shelterbelt compared to open field conditions. When water consumption of shelterbelts was added, a slight reduction of water consumption of the whole crop-shelterbelt system was found for corn, potato, and pear under the assumption 25 ha (500 × 500 m) field sizes. Under anassumption of 4 ha (200 × 200 m) field size, water consumption of the crop-shelterbelt systemwas higher for all crops investigated except for pear. The results suggest that shelterbelts may play a role in improving water resource management in Central Asia in the context of water demanding crops, like corn or cotton. In further research, other effects of shelterbelts, like increased crop yields and additional income from trees, need to be investigated.

title: Replication Data for: Determinants of livelihood vulnerability in farming communities in two sites in the Asian Highlands

description: This dataset was moved to: https://doi.org/10.34725/DVN/0YTDW7To identify the indicators of adaptive capacity that determine vulnerability of households, an intensive investigation was conducted in farming communities at two locations in the Asian highlands. Livelihood vulnerability was assessed, classified to four categories and regressed against current adaptive capacity using logistic regression. Household head’s education, irrigated land, non-agricultural income, and technologies used were associated with adaptive capacity. The strengthening of human, natural and financial capital is identified as the best means of managing risk in farming communities in this mountainous region.

title: The cover uncovered: bark control over wood decomposition

description: This dataset was moved to: https://doi.org/10.34725/DVN/5PQSTAWoody debris (WD) represents a globally significant carbon stock and its decomposition returns nutrients to the soil while providing habitat to microbes, plants and animals. Understanding what drives WD decomposition is therefore important. 2. WD decomposition rates differ greatly among species. However, the role of bark in the process remains poorly known. 3. We ask how, and how much, interspecific variation in bark functional traits related to growth and protection have afterlife effects on the decomposition of wood, partly mediated by animals. We examine the roles of bark cover and bark traits throughout the wood decomposition process. 4. Synthesis. We find that: (i) bark effects on WD decomposition are species- and wood size-specific, (ii) bark can enhance coarser WD decomposition but slows twig decomposition in some species, and (iii) bark acts as an environmental filter to faunal assemblages in the early stage of wood decomposition. We highlight the need to account for bark effects on WD decomposition and offer an important complementary contribution to including woody species identity effects in biogeochemical and climate-change models via species bark traits.

title: Rubber tree allometry, biomass partitioning and carbon stocks in mountainous landscapes of sub-tropical China

description: This dataset was moved to: https://doi.org/10.34725/DVN/5RNWFSExpansion of rubber plantations into sub-optimal environments has been a dominating land conversion in continental South-East Asia in the last decade. Regional evaluation of the carbon sequestration potential of rubber trees depends largely on the selection of suitable allometric equations and the biomass-to-carbon conversion factor. Most equations are age-, elevation-, or clone-specific, and their application therefore gives uncertain results at the landscape level with varying age groups, elevation ranges, and clone types. Currently, for rubber-based systems, none of the allometric equations takes environmental factors (e.g. climate, topographic condition, soil properties, and management scheme) into consideration to allow pan-tropical usage. Against this background, 30 rubber trees with a root profile of up to 2 m were destructively harvested and 882 rubber trees were measured non-destructively in 27 plots, covering rotation lengths of 4–35 years, elevation gradients of 621–1127 m, and locally used clone types (GT1, PRIM600, Yunyan77-4) in mountainous South Western China. Allometric equations for aboveground biomass (AGB) estimations considering diameter at breast height (DBH), tree height (H), and wood density were evaluated. We also tested goodness of fit for the recently proposed pan-tropical forest model, which includes a bioclimatic factor E, combining indices of temperature and precipitation variability and drought intensity.

title: Utilizing the Nutritional Potential and Secondary Plant Compounds of Neglected Fruit Trees and Other Plant Species of the Walnut-Fruit Forests in Kyrgyzstan

description: This dataset was moved to: https://doi.org/10.34725/DVN/FMW4ZXForests make significant contributions to safeguarding agricultural production, food security, and nutrition of rural and urban populations. The walnut-fruit forests in Kyrgyzstan constitute a unique resource in this regard and are of global importance as a biodiversity hotspot. However, current patterns of forest management are unsustainable, vast parts of the forests are overaged, and derived benefits are unequally distributed among local populations. Walnut (Juglans regia L.) kernels have traditionally been used for human diets and constitute an economically important product of these forests. Although the walnut value chain in Kyrgyzstan is of significant economic importance, the level of domestic processing is weak and locally manufactured outputs are of low quality. The SUSWALFOOD project (BMBF, funding code 01DK17016) aims at contributing to the development of nutritious food from neglected and underutilized plant species of the Kyrgyz walnut-fruit forests, thereby improving local food security, promoting sustainable forest management, and increasing local incomes. Initial analyses have investigated timber growth of walnut trees and quality parameters of respective nuts from various parts of the forests. Regarding quality parameters, nut dimensions and weight, kernel weight, and rupture force were determined to result in a classification of the investigated trees. Results show that most trees are old and may, therefore, be anticipated to display declining walnut yields, underlining the need for forest rejuvenation. Timber and nut quality varied considerably across the study area. These results will facilitate the selection of superior trees for forest regeneration. Further work in this project aims to (a) analyze the nutritional composition and secondary plant compounds of other selected plant species of the walnut-fruit forests and their potential use in new food products; (b) further investigate the morphology, diversity, and plant-soil interaction of these species to determine their biological productivity and to support sustainable management and conservation efforts; and (c) examine pecific impacts of traditional and contemporary utilizationincluding market chains and cost-benefit assessments at the household level.

title: Trading Natural Riparian Forests for Urban Shelterbelt Plantations—A Sustainability Assessment of the Kökyar Protection Forest in NW China

description: This dataset was moved to: https://doi.org/10.34725/DVN/IVMLZICities at the fringe of the Taklimakan desert in NW China are prone to dust and sand storms with serious consequences for human well-being. The Kökyar Protection Forest was established in the 1980s as an ecological engineering project with the intent of protecting the city of Aksu, NW China, from these impacts. It is designed as a combination of poplar shelterbelts and orchards, irrigated by river water from the Aksu River, the main tributary of the Tarim River. Prevalent literature describes it as an afforestation project for combatting desertification with manifold positive effects for the economic, social, and environmental dimension of sustainable development. This paper sets out to challenge these claims by a sustainability assessment in which the plantation is examined from a broader perspective, embedding it to the wider context of social and environmental problems in South Xinjiang. Methods comprise evapotranspiration calculations, interviews, a socioeconomic household survey, stakeholder dialogues, and literature research. Results affirm its economic sustainability, but see a mixed record for the social sphere. From the nature conservation point of view, it has to be classified as unsustainable because its high irrigation water consumption results in the downstream desiccation and desertification of natural riparian forests along the Tarim River, causing a forest loss in the downstream area twice the size of the forest gain in the upstream area. There is a trade-off between artificial shelterbelt plantations for urban ecosystem services on the one hand side, and natural riparian forests and their biodiversity on the other hand side. The paper recommends restricting agricultural extension, and using locally adapted less water consuming agroforestry schemes to protect urban dwellers from dust stress.

title: Spatial and seasonal variation in soil respiration 1 along a slope in a rubber plantation and a natural forest in Xishuangbanna, SW China

description: This dataset was moved to: https://doi.org/10.34725/DVN/QARZHYSoil respiration is a key component of the global carbon cycle, and even small changes in soil respiration rates could result in significant changes in atmospheric CO2 levels. The conversion of tropical forests to rubber plantations in SE Asia is increasingly common, and there is a need to understand the impacts of this land-use change on soil respiration in order to revise CO2 budget calculations. This study focused on the spatial variability of soil respiration along a slope in a natural tropical rainforest and a terraced rubber plantation in Xishuangbanna, SW China. In each land-use type, we inserted 105 collars for soil respiration measurements. Research was conducted over one year in Xishuangbanna during May, June, July and October 2015 (wet season) and January and March 2016 (dry season). The mean annual soil respiration rate was 30% higher in natural forest than in rubber plantation and mean fluxes in the wet and dry season were 15.1 and 9.5 Mg C ha-1 yr-1 in natural forest and 11.7 and 5.7 Mg C ha-1 yr-1 in rubber plantation. Using a linear mixed effects model to assess the effect of changes in soil temperature and moisture on soil respiration, we found that soil temperature was the main driver of variation in soil respiration, explaining 48% of its seasonal variation in rubber plantation and 30% in natural forest. After including soil moisture, the model explained 70% of the variation in soil respiration in natural forest and 76% in rubber plantation. In the natural forest slope position had a significant effect on soil respiration, and soil temperature and soil moisture gradients only partly explained this correlation. In contrast, soil respiration in rubber plantation was not affected by slope position, which may be due to the terrace structure that resulted in more homogeneous environmental conditions along the slope. Further research is needed to determine whether or not these findings hold true at a landscape level.

title: Soil respiration in sloping rubber plantations and tropical natural forests in Xishuangbanna, China

description: This dataset was moved to: https://doi.org/10.34725/DVN/SQA0DUSoil respiration (SR) plays an important role in the global carbon cycle. The widespread and continued conversion of tropical forests to plantations is expected to drastically alter CO2 production in soil, with significant consequences for atmospheric concentrations of this crucial greenhouse gas. In Southeast Asia, rubber plantations are among the most widespread monoculture tree plantations. However, knowledge of how SR differs in rubber plantations compared to natural forests is scarce. In this study, surface CO2 fluxes and soil CO2 concentrations (at 5 cm, 10 cm, 30 cm and 70 cm depths) were measured at regular intervals over a one-year period along slopes at three sites in paired natural tropical forests and mature rubber plantations. Annual surface soil CO2 fluxes were 15% lower in the rubber plantations than in natural forest. This difference was due to substantially lower SR during the dry season in rubber plantations compared to natural forest. During the wet season, SR did not differ significantly between rubber plantations and natural forests. In rubber plantations, soil moisture increased from lower and middle to upper slope positions, but this did not significantly impact SR. Throughout the year, net CO2 production per unit volume in the topsoil (2.5–7.5 cm) exceeded by 2–3 orders of magnitude net CO2 production in the subsoil (7.5–50 cm). However, CO2 originating from 5 cm depth and below in both land cover types could only explain up to 30% of the aboveground measured CO2 flux, indicating that&gt;70% of the total CO2 respired and emitted to the atmosphere originated from the uppermost few cm of the soil. Net CO2 production at different soil depths did not differ significantly between rubber plantations and natural forests. Our results indicate that SR characteristics in mature rubber plantation and natural forest were broadly similar, although dry season soil surface CO2 fluxes were lower in rubber plantations. However, further information on the drivers of CO2 production in the uppermost topsoil layers which are responsible for most CO2 emissions is needed to understand the extent to which these results are generalisable.

title: Replication Data for: Farmers' Perceptions of and Adaptations to Changing Climate in the Melamchi Valley of Nepal

description: This dataset was moved to: https://doi.org/10.34725/DVN/ZEPGD7Knowledge of farmers’ perceptions of and adaptations to climate change is important to inform policies addressing the risk of climate change to farmers. This case study explored those issues in the Melamchi Valley of Nepal through a survey of 365 households and focus group discussions in 6 communities using a Community-Based Risk Screening Tool–Adaptation and Livelihoods (CRiSTAL). Analysis of climate trends in the study area for 1979–2009 showed that mean annual temperatures rose by 1.02uC and the frequency of drought increased measurably after 2003. Farmers reported increases in crop pests, hailstorms, landslides, floods, thunderstorms, and erratic precipitation as climate-related hazards affecting agriculture. They responded in a variety of ways including changing farming practices, selling livestock, milk, and eggs, and engaging in daily wage labor and seasonal labor migration. With more efficient support and planning, some of these measures could be adjusted to better meet current and future risks from climate change.
