Abstract: The shortage of water resource severely affect the sustainability of the agricultural systems in the arid regions of China. Enhancing water use efficiency of irrigated agriculture is a high priority for agricultural improvement in China. Alternate Partial Root-zone Furrow irrigation (AFI) has been proved to be an effective water-saving irrigation method in the oasis field of northwest China, whereas the responses of soil temperature to AFI was seldomly studied. In this study, the field experiment was carried out in 2007 at Xuebai Experimental Station of Minqin Agricultural Extension Center of Gansu to study the changes of soil temperature as well as physiological responses of cotton to different irrigation regimes, i.e. alternate partial root-zone furrow irrigation (AFI, neighboring two furrows alternatively watered) and conventional furrow irrigation (CFI, all furrows watered) under plastic film mulching with the same irrigation level (24 mm for each irrigation). Results indicated that the differences of soil temperature of two neighboring furrows in AFI were significant (P<0.05), the values of the drying furrow always being higher than those of the irrigated ones. The data also showed that when approaching the next irrigation cycle, both the two furrows in AFI had similar soil temperature at the depth of 0-25cm. Soil temperature difference between the irrigated and the drying furrows reached as high as 4°C after irrigation, and decreased to almost 0°C at the end of the irrigation cycle. The difference of daily average soil temperature of ridge between AFI and CFI during the growing season was not apparent in the first and second irrigation cycle, whereas in the third and fourth irrigation cycle (approximately after the budding stage), the differences between them become significant(P<0.05); there were significant positive linear relationships between Tn/Ts (the ratio of average soil temperature of north furrows and south furrows) and SWCw/SWCd (the ratio of average SWC of irrigated furrows and the drying ones) (R2=0.703, P<0.01); The WUE-A/WUE-C(the ratios of WUE of AFI and CFI) were more than 1.0 in the first few days after irrigation, whereas at the end of the irrigation cycle, the value declined to be the lowest (0.75); There was no significant difference for the seed cotton yield of AFI and CFI, whereas the percentages of pre-frost seed cotton of AFI was significant higher than that of CFI (P<0.05). This study could provide valuable data for the implement of AFI in the oasis field of northwest China.

Abstract: Experimental results revealed that solution pH was one of the most important factor which effected not only phosphorus recovery percentage but also phosphorus recovery rate during the struvite forming process. Introduction of seed materials increased the phosphorus recovery percentage to an extent and optimum seed particle range and adding amount were 70-140 mesh and 0.5g (solution pH=8.5). The one-stage seed addition worked better than multi-stage addition and phosphorus recovery percentage rose with increasing initial seed dosing. Seed addition speeded the phosphorus recovery rate to some extent on the whole.

Abstract: The study intended to establish potentials of forests in adaptation to climate change with references to North Nguu Mountain block communities. The major questions to be answered were as follows: 1. How do forests in the north Nguu Mountain blocks buffer local people to the impacts of climate change? 2. What resources are taped from the forests as a way to adapt to climate variability and change in the study area?To collect data, a questionnaire was administered to a sample population. Also focus groups discussions were conducted in the study villages and finally in-depth interviews with key informants were also usedto collect data. Content analysis was used to analyze collected data. Findings show that people living adjacent to the North Nguu Forests uses forests goods and services as buffers to the impacts of climate change. Resources that are taped from the forests are those that enable communities diversify and broaden their livelihood horizons; these include arable land, timber as well as the non-timber forest productssuch as wild fruits, berries, nuts and vegetables, honey, medicinal plants, grazing fields, game and game products, mining as well as water sources. Local people also benefit from conducive weather conditions i.e. sufficient and timely rainfall events accompanied with moderate temperatures. The study concludes that forests play a significant role in adaptation to climate change in the study area. However, the study also concludes that although most people use forests products and services to improve income and hence the general well being, they poorly conceive the relationship between forests and climate change. This has negative implications on sustainable forest resources use where over utilization and the general forests degradation are likely. The study therefore suggests that policy intervention is urgently required to promote sustainable resources utilization which in turnwill lead to increase of resources taped from the forests for adaptation to climate variability and change.

Abstract: Across the globe and for several decades, conflicts have enormously damaged the environment leading to severe ecological degradation. In this paper, we look at ecological degradation in conflict and post-conflict societies and analyze how these could be managed. To attain this goal, we carry out a review of published literature and survey the vast resources sourced from various civil society organizations. We observed that the environment is rarely viewed as an important aspect during conflicts or after conflicts despite being in a context of ravaged infrastructure, lost livelihoods and disrupted institutions. Moreso, these conflicts do extraordinary damage to the ecological component as people struggle for clean water, sanitation, food and fuel. We surmise that, in periods of conflicts and post-conflicts, severe environmental challenges emerge which necessitate the establishment of environmental governance especially of the natural resource base, creation of administrative capacity and seeking sustainable trajectories for environmental recovery as well as reconstruction.

Abstract: Guilin is trying to be an international tourist destination. Climate resources development and utilization can play a catalytic role in the sustainable development of tourism. By analyzing the climatic resources of tourism in Guilin, the climate conditions, meteorological disasters and climatic comfort of 13 stations in Guilin were studied. The city has clear four seasons, with short winter cold and summer heat, and the accumulated temperature conditions, rainfall, sunlight, wind is proper for tour; all of these bring a high human comfort. Guilin’s climate is very beneficial to the ecological environment, biological species and picturesque scenery, which is very suitable for living and tourism. While, meteorological disasters also occur from time to time, so in the tourism project development we need to pay great attention for it.
