“…This method uses modelling based on the province-scale socio-economic data to account for cases when crop losses were high during relatively minor meteorological droughts versus cases when crop losses were minimal during relatively large meteorological droughts. Mechanisms leading to this observation include, for example, the use of farm labour to minimize the impact of poor irrigation systems [32]. Following [20], a vulnerability index (VI) was defined as the ratio of a crop failure index to a drought index.…”

Tools for projecting crop productivity under a range of conditions, and assessing adaptation options, are an important part of the endeavour to prioritize investment in adaptation. We present ensemble projections of crop productivity that account for biophysical processes, inherent uncertainty and adaptation, using spring wheat in Northeast China as a case study. A parallel 'vulnerability index' approach uses quantitative socio-economic data to account for autonomous farmer adaptation.The simulations show crop failure rates increasing under climate change, due to increasing extremes of both heat and water stress. Crop failure rates increase with mean temperature, with increases in maximum failure rates being greater than those in median failure rates. The results suggest that significant adaptation is possible through either socio-economic measures such as greater investment, or biophysical measures such as drought or heat tolerance in crops. The results also show that adaptation becomes increasingly necessitated as mean temperature and the associated number of extremes rise. The results, and the limitations of this study, also suggest directions for research for linking climate and crop models, socio-economic analyses and crop variety trial data in order to prioritize options such as capacity building, plant breeding and biotechnology.

“…Physical or management improvements are needed at all levels before substantial improvements in performance can be taken. Deng et al [7] added that mechanization and technology application are keys to increase production. In addition, non-technical factors other than being described above such as pests and plant diseases, rodents and fertilizer also affected the yield of the crop farmers.…”

This research is aimed to study the production cost for determining feasibility and return of investment (ROI) of farming and farmer income based on the crop yield in the Pante Lhong technical irrigation system. These system performances were evaluated using measured/rewarded/collected internal and external indicators that covered different aspect of evaluation. The Rapid Appraisal Process (RAP) is a visual assessment tool was used to evaluate the external indicators performance. The external indicators were crop yield and production cost. The data of crop yield and production cost were collected from the farmers in the three regions which were upstream, middle stream and downstream. Data were collected through field observation and face to face interviews with the irrigation staff and the farmers. The production cost data were calculated based on the land preparation cost, growth stage cost and harvesting cost. In the crop yield indicator, the average maximum productivity was 3.91 ton/ha and the income generated was Rp.11.730 million rupiahs/ha (US$ 1289/ha). The total production cost of the Pante Lhong technical irrigation system was Rp. 4.126 million rupiahs/ha (US$ 453.50/ha) and hence in term of return of investment (ROI), it is still profitable and feasible to be developed for the farmers.

“…On the other hand, because groundwater levels depend on the extent of seepage of irrigation water [4], the groundwater resources decrease if seepage is prevented. Moreover, exhaustion of groundwater resources by widespread pumping has been recorded by Xinan Deng et al [5] and others. To summarize, sustainable and effective utilization of groundwater is not a simple matter.…”

Irrigation is indispensable in guaranteeing agricultural production in arid regions, such as the Tarim Basin. In this region, administrations and farmers have reclaimed wild land, and have attempted agricultural development by securing the water resources. However, this area faces problems with an extremely irrational plan between land reclamation and water resource development, which has resulted in an acute shortage of water in this region. The situation has also caused ecological damage. This paper discusses this region's problems with agricultural water use and farmer's activities. It is shown that water supply volume per unit of farmland is tending to decrease. It is also clear that the water supply from the river has decreased greatly in the region where water-saving irrigation by groundwater pumping was introduced earlier. Water-saving irrigation is being introduced to resolve the water shortage and create new water resources. Although it seems to be effective for saving water resources, improper management hinders effective irrigation in this region. In particular, considering that water management is different among landowners and farmers, it has become clear that there are several problems -lack of an adequate management system and training system for facilities maintenance, etc.that need to be resolved for water-saving irrigation in the region.
