The first Water Accounting summer course reflects the increased need to have independent and open access data to support water resources management. During this week we presented the Water Accounting Plus framework (WA+), which is strongly based on Remote Sensing, to 31 participants coming from 19 different countries. Academic UNESCO-IHE students and external participants from national and international, public and private sectors (ADB, WB, ACIWRM, DGIS and Jain irrigation) joined together to learn more about WA+.
The journey started from understanding the needs from a political and institutional point of view. The UNESCO-IHE rector Dr. Fritz Holzwarth gave an inspiring lecture stating how WA+ could support international water policy negotiations. Our global water accounting professor, Dr. Wim Bastiaanssen, explained all the fundamental concepts behind the WA+ framework, shared his long experience in water studies and in the use of the latest technology for agriculture and water management. The pool of teachers included: Dr. Elga Salvadore (course coordinator, theory and exercises on WA+), Dr. Gonzalo Espinoza (open access databases for WA+ and exercises with spatial data), MSc Tim Hessels (exercises with spatial data), Dr. Jonna van Opstal (Water Productivity theory and exercises), Dr. Cai Xueliang (link between WA+ and SDGs). Many technical aspects were also addressed with practical exercises, among others: how to download essential data from open access databases, GIS and Remote Sensing data analysis and computer programming for WA+ computations. Water productivity was one of the pillars of the past week and we would like to thank Dr. Kleijn from the Dutch Ministry of External Affairs for sharing with the participant the government perspective on this relevant topic. Finally, the WA+ framework represents a step forward in promoting Water Democracy and we are sure this summer course is just the beginning!

Dr. Pasquale Steduto from the Near East and North Africa (NENA) region of the FAO organized an important conference on "Water Consumption, Water Productivity and Drought Management in Agriculture” in Cairo during 27 to 29 October (2015). The workshop has been attended by more than 100 participants under the auspice of the Egyptian Minister of Water Resources and Irrigation, and considered a land mark meeting bringing together countries and partners in developing relevant and concrete work plan and results for the coming years. The workshop has also received a significant media coverage with more than 60 articles across the region, including 15 in top tier sources.
The presentations can be accessed here.
The WaterAccounting.org group advocated the need to cap the volume of water consumed in agriculture, both green and blue water resources. This is a pre-requisite for achieving sustainable and economically profitable agriculture in arid zones. Investments will stay away if the total water picture is absent.

NASA and the Worldbank organized a joint workshop to evaluate the state-of-art on the mapping of evapotranspiration from remote sensing techniques. This was a unique gathering between the suppliers of the raw data, the scientists and the user community. Prof. Dr. Wim Bastiaanssen provided a lecture on the international experiences, and pleaded for a global ensemble ET product. It is clear that water accounting cannot be accomplished without NASA satellites, although ESA together with China have constructive progress on future earth observation missions. First presentations of on-line ET processing on the Earth Engine were provided (http://eeflux-level1.appspot.com/). It is interesting to note that this EEFlux algorithm (source: Rick Allen and Ayse Kilic) is based on SEBAL, and that many of the original functions on hot and cold pixel selection are unchanged since 1995. All presentations will come on-line soon.

Wateraccounting.org has co-organized a workshop at the 2015 Stockholm water week dealing with crop water productivity. It was emphasized that although water productivity is formally recognized under SDG goal 6.4, it should under all circumstances be implemented in a sustainable manner. This implies that crop water productivity should be associated with rainfed and irrigation related water consumption, and be balanced with other water users in a river basin context.

The water accounting team welcomes Tim Hessels (M.Sc), who replaces Gert Mulder (M.Sc) as the major hydrological programmer at UNESCO‑IHE. Tim graduated from Delft University of Technology in Water Resources Management and Remote Sensing on a thesis entitled ”Comparison and Validation of Several Open Access Remotely Sensed Rainfall Products for the Nile Basin” during February 2015. Tim will continue to develop Python based tools that are used to collect data from internet and integrate them to generate the various standardized maps, tables and sheet of WA (see section Formulation on this website). With this software, it will become feasible to generate water accounts automatically. IWMI has selected Mansoor Delali Kwasi Leh (Ph.D.) from Ghana / USA to assist the WA team with the quantification of ecosystem services. Mansoor holds a Ph.D. from the University of Arkansas (2001) and he is an experienced SWAT modeller and GIS expert. Welcome to the team Mansoor and Tim!

SERVIR Mekong is one of four SERVIR hubs currently operating across the developing world. SERVIR connects USAID’s development network in data‑poor environments with NASA’s science, technology and extensive satellite data. It will help governments and other key decision‑makers in Burma, Cambodia, Laos, Thailand and Vietnam take advantage of publicly available satellite imagery, geospatial data and maps to make more informed decisions on issues such as water management, land use planning, disaster risk reduction, infrastructure development and natural resource management (read more).
The University of San Francisco (Dr. David Saah) and University of Colorado (Dr. Austin Troy) have requested UNESCO‑IHE to co‑develop an ”Ecosystem Service Value Baseline”. According to Mark Fenn from the Winrock Vietnam Forest and Delta project, this endeavour will help to assess ”the status of Natural Capital, something similar to GDP” by a push on the button.

The Asian Development Bank has signed a top‑up agreement with UNESCO‑IHE on several activities. One activity relates to the preparation of the water accounts of all 16 major river basins of Vietnam. IWMI‑Laos is a sub‑contractor in this project for providing Asian ownership. The project partners in Vietnam will be NAWAPI and IWRP, and the kick‑off workshop is planned for early August. ADB provides technical assistance to Vietnam on the preparation of the ”Country Water Assessment Vietnam”, and feels that a standard data collection system with a systematic reporting on various relevant water management issues is necessary to raise the plan to a higher level. WA is a suitable tool for that, and Vietnam will be a test case. In the case of positive evaluation, WA could also be considered as an input into the Asian Water Development Outlook, one of the most comprehensive water reviews of all 49 countries in Asia (www.adb.org/publications/asian-water-development-outlook-2013).

Mrs Marlies Barendrecht (M.Sc.) successfully defended her Master Thesis entitled ”Bridging the Information Gap between Scientists and Decision Makers in the Eastern Nile” at Delft University of Technology. She interviewed 35 water professionals in Egypt, Sudan and Ethiopia up to Minister level. The major recommendation is that WA should reach out to the scientific advisors of Ministers. The respondents conclude that WA is (i) a useful concept and (ii) that it provides basic understanding of water resources in a river basin. More attention needs, however, to be given to (i) validation, (ii) compilation of short messages that can be understood by policy makers and (iii) preparation of water accounts at country level (rather than at basin level). We congratulate Marlies with her interesting piece of work at the downstream end of water accounting.

Mr. Ha Thanh Lan from the Institute of Water Resources Planning (MARD) and Ms. Na Nguyen from the Department of National Remote Sensing (MONRE) in Vietnam have decided to both embark on a Ph.D. study related to water accounting and ecosystem services (see news March 2015). Mr. Lan will focus on the integration of remote sensing and hydrological models for determining various water regulation related ecosystem services. Ms. Nguyen will concentrate her work on remote sensing and the carbon balance of forests, with an emphasis on carbon sequestration and reduction of greenhouse gas emissions. She will study the link between rainfall, soil moisture and carbon pools in forested areas of the Ca basin. Spatial modelling of carbon fluxes could replace the outdated look-up tables between land use and carbon stocks as fixed numbers. These talented young professionals are considered to become the future leaders of water accounting in Vietnam.

As part of the MK27 healthy Red River project, a dedicated workshop was organized by IWMI in Vientiane to discuss elementary ecosystem services that could become a standard component of WA . It was found by the participants that the consumptive use of green and blue water should be related to ecosystem services in general, and not to agricultural services only. This is basically a plea for an expanded view on the water productivity concept. A list of 27 ecosystem service indicators has been formulated that can potentially be quantified by means of remote sensing and hydrological models. This can be considered as the blueprint for the research agenda on water accounting and ecosystem services (see April 2015). A first assessment to describe sustainable river basins has been made, and time series of key (state) variables will form the basis to quantify resilience, vulnerability and reliability processes. This sustainability related information should form the basis of WA sheet 8.

The FAO division for Land and Water has executed a WA study in the Helmand basin, Afghanistan. The work has been mainly executed by Livia Peiser and Jippe Hoogeveen from FAO based out of Rome.
Both experts were involved earlier in the water accounting studies of Okavango and Awash basins. Wim Bastiaanssen provided limited back up support. The study is a confirmation that earth observation data is a proper methodology for basins and countries where data is scant and field measurement programs and visits are difficult to organize. The final report is available on this website.
