Successful identification and mapping of different cropping patterns under cloudy conditions of a specific crop through remote sensing provides important baseline information for planning and monitoring. In Vietnam, this information is either missing or unavailable; several ongoing projects studying options with radar to avoid earth observation problems caused by the prevailing cloudy conditions have to date produced only partial successes. In this research, optical hyper-temporal Satellite Pour l’Observation de la Terre (SPOT) VEGETATION (SPOT VGT) data (1998–2008) were used to describe and map variability in irrigated rice cropping patterns of the Mekong delta. Divergence statistics were used to evaluate signature separabilities of normalized difference vegetation index (NDVI) classes generated from the iterative self-organizing data analysis technique algorithm (ISODATA) classification of 10-day SPOT NDVI image series. Based on this evaluation, a map with 77 classes was selected. Out of these 77 mapped classes, 26 lasses with prior knowledge that they represent rice were selected to design the sampling scheme for fieldwork and for crop calendar characterization. Using the collected information of 112 farmers’ fields belonging to the 26 selected classes, the map produced provides highly accurate information on rice cropping patterns (94% overall accuracy, 0.93 Kappa coefficient). We found that the spatial distributions of the triple and the double rice cropping systems are highly related to the flooding regime from the Hau and Tien rivers. Areas that are highly vulnerable to flooding in the upper part and those that are saline in the north-western part of the delta mostly have a double rice cropping system, whilst areas in the central and the south-eastern parts mostly have a triple rice cropping system. In turn, the duration of flooding is highly correlated with the decision by farmers to cultivate shorter or longer duration rice varieties. The overall spatial variability mostly coincides with administrative units, indicating that crop pattern choices and water controlmeasures are locally synchronized. Water supply risks, soil acidity and salinity constraints and the anticipated highly fluctuating rice market prices all strongly influence specific farmers’ choices of rice varieties. These choices vary considerably annually, and therefore grown rice varieties are difficult to map. Our study demonstrates the high potential of optical hyper-temporal images, taken on a daily basis, to differentiate and map a high variety of irrigated rice cropping patterns and crop calendars at a high level of accuracy in spite of cloudy conditions.

Variability in water cycles driven by climate change is considered likely to impact rice production in the near future. Rice is the main staple food for the population in the lower Mekong Basin and the demand for food is expected to grow due to increase in population. This paper examines the impact of climate change on rice production in the lower Mekong Basin, evaluates some widely used adaptation options, and analyses their implications for overall food security by 2050. Climate change data used in the study are the future climate projection for two IPCC SRES scenarios, A2 and B2, based on ECHAM4 General Circulation Model downscaled to the Mekong region using the PRECIS (Providing Regional Climates for Impact Studies) system. In general, the results suggest that yield of rainfed rice may increase significantly in the upper part of the basin in Laos and Thailand and may decrease in the lower part of the basin in Cambodia and Vietnam. Irrigated rice may not be affected by climate change if increased irrigation requirements are met. Negative impact on the yield of rainfed rice can be offset and net increase in yield can be achieved by applying widely used adaptation options such as changing planting date, supplementary irrigation and increased fertilizer input. Analysis of the projected production, considering population growth by 2050, suggests that food security of the basin is unlikely to be threatened by the increased population and climate change, excluding extreme events such as sea level rise and cyclones.

There is growing concern about the potential effects of climate change on the natural resources of the Lower Mekong River Basin (LMB). It is therefore no surprise that climate change adaptation has become one of the focal points of current development discussions in the region. Here we examine the impact of climate change on the rice cultivation of the LMB and its consequences for overall food security and possible adaptation options. Rice is the main staple food for the population and the demand for food is expected to grow due to increase in population. Variability in water cycle driven by climate change is considered likely to impact rice production in the near future. Thus, rice cultivation faces greatly increased demands for food on the one hand, and several threats to production due to climate change on the other. Against this background, it is important to examine the adaptation options to reduce the vulnerability of Mekong food security to impact of climate change and population growth.We have assessed the impact on the productivity of rice grown in the basin using a crop simulation model – AquaCrop. In general, the results suggest that productivity of main rainfed rice, predominant crop in the basin, may increase significantly in the upper part of the basin in Laos and Thailand and may decrease in the lower part of the basin in Cambodia and Vietnam. Irrigated rice may not be affected by climate change if increased irrigation requirements are met. We have tested widely used adaptation strategies such as shifting planting date, supplementary irrigation and reduction of fertility stress and found that negative impact on the yield can be offset and net increase in yield can be achieved. Hence food security of the basin is unlikely to be threatened by the increased population or climate change.

The global water resources are stressed due to high population pressure, demand for more and better food, over-exploitation of the surface and groundwater resources, urgent need to make provisions for the environmental services, and meet the expanding demands of non-food sectors. As a consequence, pollution is increasing and rivers are drying up because of greater agricultural production and water consumption; land and water resources are being stressed through erosion, salinization, nutrient depletion and the intrusion of seawater; and groundwater levels are declining rapidly in densely populated areas of North Africa, North China, India, and Mexico because of overexploitation. Increasing water withdrawals and water depletion for irrigation under such stressed conditions further aggravates the severity of the already stressed environments. Unfortunately, in most developing countries, water infrastructure and management institutions have been slow to build or improve capacity and adapt to new issues and conditions. Additionally, the world is facing the new challenges of climate change affecting temperature and precipitation patterns hitting the poor and the rainfed farmers more severely; urbanisation increases demand for water and generates more wastewater; higher energy prices increase the cost of pumping water; and more attention is being given to ecosystem services of water.

Assessment on impact of climate change on major crops in ecologically sensitive areas, viz. the Western Ghats (WG), coastal districts and northeastern (NE) states of India, using InfoCrop simulation model, projected varying impacts depending on location, climate, projected climate scenario, type of crop and its management. Irrigated rice and potato in the NE region, rice in the eastern coastal region and coconut in the WG are likely to gain. Irrigated maize, wheat and mustard in the NE and coastal regions, and rice, sorghum and maize in the WG may lose. Adaptation strategies such as change in variety and altered agronomy can, however, offset the impacts of climate change.

Rice production in Cambodia, essential to food security and exports, is largely limited to the wet season. The vast majority (96%) of land planted with rice during the wet season remains fallow during the dry season. This is in large part due to lack of irrigation capacity, increases in which would entail significant consequences for Cambodia and Vietnam, located downstream on the Mekong River. Here we quantify the extent of the dry season ‘‘deficit” area in the Cambodian Mekong River catchment, using a recent agricultural survey and our analysis of MODIS satellite data. Irrigation of this land for rice production would require a volume of water up to 31% of dry season Mekong River flow to Vietnam. However, the two countries share an aquifer system in the Mekong Delta, where irrigation demand is increasingly met by groundwater. We estimate expansion rates of groundwater-irrigated land to be >10% per year in the Cambodian Delta using LANDSAT satellite data and simulate the effects of future expansion on groundwater levels over a 25-year period. If groundwater irrigation continues to expand at current rates, the water table will drop below the lift limit of suction pump wells, used for domestic supply by >1.5 million people, throughout much of the area within 15 years. Extensive groundwater irrigation jeopardizes access for shallow domestic water supply wells, raises the costs of pumping for all groundwater users, and may exacerbate arsenic contamination and land subsidence that are already widespread hazards in the region.

Soil nutrient supply capacity, nutrient use efficiency and fertilizer requirement for the consecutive rice cropping in irrigated system were investigated using a randomized complete block design with different fertilization treatments, including control (no fertilizer application), PK, NK, NP and NPK fertilization with four replications at Myanmar Rice Research Center (MRRC). Short duration rice varieties, Pale Thwe-1 (hybrid) and Yadanar Toc (HYV) were used to determine the soil indigenous nutrient supply capacity, to evaluate the omission plots for estimating fertilizer use efficiencies and to estimate the indigenous nutrients (N, P and K) as an requirement for working out a site specific fertilizer recommendation. The results of five treatments in four seasons indicated that the indigenous nutrient supply capacity of N, P and K (INS, IPS and IKS) ranged from (30.1 to 87.7) kg N ha-1, (8.9 to 53.7) kg P ha-1 and (43.7 to 165.3) kg K ha-1 . The nutrient use efficiencies (NUE, PUE and KUE) ranged between (2.1 to 27.8 kg kg-1 N applied), (12.8 to 63.5 kg kg-1 P applied) and (4.5 to 28.3 kg kg-1 K applied) in two rice varieties. It was also observed that rice crop could use nutrient more efficiently in dry season than in wet season. The four season's rice-rice monoculture also showed that balanced application of N, P and K promoted not only grain yield but also nutrient uptake. The yield increases of Pale Thwe-1 and Yadanar Toe over control treatment were 86, 52 % in NPK, 55, 44 % in NK and 65, and 37 % in NP a treatments, respectively. Nitrogen was the first nutrient limiting factor for yield, followed by P and then K. The greater N fertilizer requirement of Pale Thwe-1 variety was based on the greater yield target. The average amount of four season's fertilizer requirements were 160 kg N ha-1, 45 kg P ha-1 and 75 (kg K ha-1 for hybrid. Fertilizers were applied at a rate of 100 kg N ha-1, 30 kg P ha-1 and 70 kg K ha-1 for HYV. The importance of balanced fertilization in maintaining soil fertility for sustainable yield production is highly evident. The present study was conducted for only four consecutive rice cropping seasons at MRRC and the work needs further investigation.
