Prasad S. Thenkabail 博士是美国地质调查局 (USGS) 的 15 岁研究地理学家，是世界公认的遥感科学专家，在该领域的多项重大贡献已持续 30 多年。他于 1992 年从俄亥俄州立大学获得博士学位，发表了 140 多篇同行评审的科学出版物，其中大部分发表在主要的国际期刊上。 Thenkabail 博士在植被高光谱遥感领域以及全球农田及其用水保障粮食安全领域开展了开创性研究。 在高光谱遥感方面，他进行了前沿研究，在推动遥感科学应用于农业和植被方面具有广泛意义。这些工作导致了十多篇具有高影响力的同行评审研究出版物。例如，截至撰写本文时（2020 年 11 月 19 日），一篇题为“高光谱植被指数及其与农作物特征的关系”的论文已获得 1250 多次引用。另外两篇题为“用于植被分析应用的高光谱波段性能的准确性评估”和“非洲雨林研究中的 Hyperion、IKONOS、ALI 和 ETM+ 传感器”的论文各有 515+ 和 420+ 次引用（（2020 年 11 月 19 日）。许多其他论文、书籍章节和书籍（一些与这项工作相关，我们将在下面了解到）对农业、植被、水、粮食安全以及全球农田的高光谱遥感领域做出了非常重要的贡献此外，还启动了全球农作物高光谱成像光谱库（GHISA）的新探路工作：

Remote Sensing of Global Croplands for Food Security pdf 普拉萨德·滕卡佩尔

Increases in populations have created an increasing demand for food crops while increases in demand for biofuels have created an increase in demand for fuel crops. What has not increased is the amount of croplands and their productivity. These and many other factors such as decreasing water resources in a changing climate have created a crisis like situation in global food security. Decision makers in these situations need accurate information based on science. Remote Sensing of Global Croplands for Food Security provides a comprehensive knowledge base in use of satellite sensor-based maps and statistics that can be used to develop strategies for croplands (irrigated and rainfed) and their water use for food security. Over 50 Multi-disciplinary Global Experts Give Insight and Provide Practical Approaches Emphasizing practical mapping technologies based on advanced remote sensing data and methods, this book provides approaches for estimating irrigated and rainfed cropland areas and their water use on a national, continental, or global basis. Written by 50+ leading experts working at the forefront of this critical area, it offers case studies from a variety of continents highlighting the subtle requirements of each. In a very practical way it demonstrates the experience, utility, and models for determining water resources used and resulting yields of irrigated and rainfed croplands. The authors discuss: (a) innovative methods used for mapping croplands, (b) approaches adopted to collect cropland data in different countries by traditional and non-traditional means, (c) accuracies, uncertainties, and errors involved in producing cropland products, (d) surface energy balance models used to assess crop water use, and (e) extensive results and outcomes pertaining to global croplands and their water use. Develop Strategies for an Enhanced Green Revolution and an Accelerated Blue Revolution Linking croplands to water use and food security, the book provides a global perspective on this sensitive issue. It gives insight into the extent of cropland usage, their spatial distribution, their cropping intensities, and their water use patterns. The editors collect the experience, methods, models, and results that show the way forward and help in decision-making on water resources and food security. All of this is required for developing strategies for an enhanced green revolution and for an accelerated blue revolution.
