Providing global food security for an ever-growing population, predicted to reach nine billion by 2050, and reducing poverty are challenging tasks. Growing per capita income in the emerging giant economies such as Brazil, Russia, India, China and South Africa (BRICS) means increased pressure on global food production due to changing food habits. This increased food production has to be met using finite water and land resources. The quantity of available water and land has not increased since 1950, but the availability of water and land per capita has declined significantly due to an increased global human population. For example, in India, per capita water availability has decreased from 5177 m3 in 1951 to 1625 m3 in 2011 due to the population increasing from 361 million in 1951 to 1.15 billion in 2011, which is expected to rise to 1.39 billion by 2025 and 1.64 billion by 2050, with an associated decrease in per capita water availability of 1345 m3 in 2025 and 1140 m3 by 2050 (Wani et al., 2012). The distribution of water and land resources varies in different countries and regions of the world, and the current population is expected to increase rapidly. In this chapter, we analyse the current status of agricultural water use in tropical rain-fed areas, assess the potential and propose a new paradigm to manage agricultural water efficiently by adopting various land, water, nutrient and crop management technologies.
为不断增长的人口(预计到2050年将达到90亿)提供全球粮食安全以及减少贫困是具有挑战性的任务。巴西、俄罗斯、印度、中国和南非(金砖国家)等新兴经济体的人均收入不断增长，这意味着由于饮食习惯的改变，全球粮食生产面临的压力越来越大。增加的粮食产量必须利用有限的水资源和土地资源来满足。自1950年以来，可用的水和土地数量没有增加，但由于全球人口的增加，人均可用的水和土地数量显著下降。例如，在印度，由于人口从1951年的3.61亿增加到2011年的11.5亿，人均可用水量从1951年的5177立方米减少到2011年的1625立方米，预计到2025年将增加到13.9亿，到2050年将增加到16.4亿，人均可用水量相应减少到2025年的1345立方米和2050年的1140立方米(Wani et al.， 2012)。世界不同国家和地区的水资源和土地资源分布各不相同，目前的人口预计将迅速增加。在本章中，我们分析了热带雨养地区农业用水的现状，评估了潜力，并提出了一种新的范例，通过采用各种土地、水、养分和作物管理技术来有效地管理农业用水。

In this chapter, we argue that an integrated approach for estimating crop water requirements is required to account for atmospheric conditions, plant water status and soil properties. The chapter first reviews the concepts, principles, limits and advantages of the soil–plant–atmosphere–based methods to estimate crop water requirements at field level. The usefulness and complementarity of the integrated approach is then demonstrated through a case study to determine water requirements of an apple orchard in South Africa. Finally, the applicability of different methods, directions for future research and additional information for specific conditions are provided.
