The Richelieu River which starts in the Green Mountains of Vermont and Adirondack Mountains of New York, feeds into Lake Champlain, passes through the province of Quebec and enters the St. Lawrence River about 50 km or so from Montreal. Since early April, the watershed has suffered from severe flooding and there is no let up in sight. Over 3,000 homes are flooded and damaged, and several thousand hectares of prime cropland are under water. The optimum time for seeding of crops is May 23-27, given our very short growing season. It is evident that farmers will be unable to seed their crops or will seed late. Crops will not achieve maturity, and consequently yields will be significantly reduced. I have visited the flood affected lands and am left aghast at how some of the world’s most productive lands and its agriculture are reduced to nothing at this point in time. This situation of flooded cropland is equally devastating for hundreds of farmers in Manitoba, Canada and perhaps several thousand in the Mississippi basin of the US. No amount of money can replace the damage, misery, suffering and personal and emotional loss. As President of ICID, I am acutely aware that many of our member countries are affected in worse ways annually during the monsoons, typhoons and hurricanes. And here I refer not just to India, Pakistan, China, Bangladesh, Indonesia and South East Asia, but also to countries such as Australia last year, and to Colombia at this very moment. I am even more aware that in many of these countries lives and jobs are lost, damage is permanent, families are uprooted, and the vicious cycle of poverty, misery and suffering is further entrenched. It is obvious that the financial means to provide either complete structural or non-structural measures to flood proof villages, towns and watersheds are non- existent. We simply could not do it, even if we wanted. I am reminded of the enormous damage and destruction, and loss of life caused by the recent tsunami in Japan. Our Japanese colleagues and National Committee were deeply appreciative of the support and sympathy of the ICID family worldwide. Flooding has plagued human civilizations for millennia. Floods and the resultant famines left indelible marks on civilizations. We must be concerned that despite our hydrological and technological advances, the question of floods and their impact on lives and property, and local, national and international food supplies remains un- resolved. Perhaps the time has come for the ICID fraternity to share experiences, lessons learned, and best practices from our collective actions and responsibilities of having to manage floods in our respective countries. I would be pleased to receive your comments on this topic, and to see whether a special session ought to be planned either for our Tehran Congress or at an upcoming IEC. I close by thanking our Indian, French and Dutch National Committees for hosting me during their recent local and regional meetings. It was indeed an honour to participate in the deliberations and meet a wide cross section of experts. ICID is stronger because of such events, the breadth of the participants, and the richness of the dialogue. I trust that you are making plans to attend the Tehran IEC and Congress, October 15-23, 2011. Our hosts, the Iranian National Committee are working vigorously to ensure that we have a very successful Congress, and I urge you to attend and support the National Committee. I look forward to seeing you in Tehran. Yours truly, Chandra A. Madramootoo President, ICID

Dear colleagues and friends of ICID,

As I write this message, I am in themidst of analyzing the flooding, rainfall,snowmelt and hydrographic data of amajor agricultural watershed close to myhome in Montreal. The Richelieu Riverwhich starts in the Green Mountains ofVermont and Adirondack Mountains ofNew York, feeds into Lake Champlain,passes through the province of Quebecand enters the St. Lawrence River about50 km or so from Montreal. Since earlyApril, the watershed has suffered fromsevere flooding and there is no let up insight. Over 3,000 homes are flooded anddamaged, and several thousand hectaresof prime cropland are under water. Theoptimum time for seeding of crops isMay 23-27, given our very short growingseason. It is evident that farmers will beunable to seed their crops or will seedlate. Crops will not achieve maturity,and consequently yields will besignificantly reduced. I have visited theflood affected lands and am left aghastat how some of the world’s mostproductive lands and its agriculture arereduced to nothing at this point in time.

This situation of flooded cropland isequally devastating for hundreds offarmers in Manitoba, Canada andperhaps several thousand in theMississippi basin of the US. No amountof money can replace the damage,misery, suffering and personal andemotional loss.

As President of ICID, I am acutely awarethat many of our member countries areaffected in worse ways annually duringthe monsoons, typhoons and hurricanes.And here I refer not just to India,Pakistan, China, Bangladesh, Indonesia

and South East Asia, but also tocountries such as Australia last year, andto Colombia at this very moment. I ameven more aware that in many of thesecountries lives and jobs are lost, damageis permanent, families are uprooted, andthe vicious cycle of poverty, misery andsuffering is further entrenched.

It is obvious that the financial meansto provide either complete structural ornon-structural measures to flood proofvillages, towns and watersheds are non-existent. We simply could not do it,even if we wanted. I am reminded ofthe enormous damage and destruction,and loss of life caused by the recenttsunami in Japan. Our Japanesecolleagues and National Committee weredeeply appreciative of the support andsympathy of the ICID family worldwide.

Flooding has plagued human civilizationsfor millennia. Floods and the resultantfamines left indelible marks oncivilizations. We must be concerned

that despite our hydrological andtechnological advances, the question offloods and their impact on lives andproperty, and local, national andinternational food supplies remains un-resolved.

Perhaps the time has come for the ICIDfraternity to share experiences, lessonslearned, and best practices from ourcollective actions and responsibilitiesof having to manage floods in ourrespective countries. I would be pleasedto receive your comments on this topic,and to see whether a special sessionought to be planned either for ourTehran Congress or at an upcoming IEC.

I close by thanking our Indian, Frenchand Dutch National Committees forhosting me during their recent localand regional meetings. It was indeed anhonour to participate in the deliberationsand meet a wide cross section ofexperts. ICID is stronger because of suchevents, the breadth of the participants,and the richness of the dialogue.

I trust that you are making plans toattend the Tehran IEC and Congress,October 15-23, 2011. Our hosts, theIranian National Committee are workingvigorously to ensure that we have avery successful Congress, and I urgeyou to attend and support the NationalCommittee.

General forum focus of the WWF6 ison “Time for Solutions.” The forum is

organized along with 3 Strategic Directions,12 Priorities for Action, and 3 Conditionsfor Success. The 3 Strategic Directionsviz., (i) Ensure everyone’s wellbeing, (ii)contribute to economic development, and(iii) Keep the planet blue, are in line withthe 3 pillars of sustainable development.The 12 Priorities for Action are groupedunder 3 Strategic Directions. For eachPriority for Action a specific Goal hasbeen formulated providing additionalguidance for the implementation of targetsand solutions. Solutions are the concreteactions required to achieve the targets.This goal and its related targets is intendedto become an important contribution tothe global water agenda and in particularto the Rio+20 Summit to be organizedby the UN.

The focus of WWF6 is on targets andsolutions. In order to achieve this in thepast there have been various meetings anddiscussions leading to draft documents thatwill be further elaborated and improved inthe coming period up to WWF6. There isa thematic process, a regionalprocess and a political process.A schematic representation ofthe process involved in thedevelopment of ‘solutions’ forWWF6 is shown in the figure.

During mid April, theInternational Forum Committeepublished its decisions on theTargets, the Core Groupsand the Target and SolutionGroups. All details can befound on the Forum website:www.worldwaterforum6.org.

For Thematic Priority 2.2 the coordinatorof the Core Group is FAO - PasqualeSteduto - and co-coordinator ICID – BartSchultz. For thematic Priority 2.1, AFEID -Francois Brelle - is the coordinator. WithinThematic Priority 2.2 there will be eightTargets as follows:

(i) By 2020, sustainably increase byxx percent - as compared to 2005 -2007 baseline - land and waterproductivity (yield per ha and per m3)of rainfed agriculture (for specific cropcategories);

(ii) By 2020, sustainably increase byX percent - as compared to 2005 -2007 baseline - water productivityper unit land and per year (yield perm3 per ha and per year) of irrigatedagriculture (for specific cropcategories);

(iii) Increase productivity and lower costsof irrigated agriculture (yield per ha,per m3 of water and per $$ ofproduction cost) in such a way thatby year 20yy there is food securityat affordable prices for all;

(iv) By year 20yy, increase by x percent -as compared to 2005 - 2007 baseline- the safe use of non-conventionalwaters, either (treated) wastewater orother low-quality water, in agriculture;

(v) By year 20yy increase by xx percentthe capacity of water storages insupport of irrigated agriculture(either supplementary, deficit, or fullirrigation) - within the framework ofan environmentally sufficient andsocially sound management;

(vi) By 20yy, develop and adopt two“regional” (e.g. West Africa; Europe /Euro-Med) visions for food securityand water, and 200 local sustainableagriculture plans;

(vii) By 20yy, develop national strategicaction programmes for key ‘hotspot’aquifers exploited by intensive agricul-tural use (percent aquifer depletion,percent pollution), including a localdefinition of maximum admissibledrawdown (MAD) and local definitionof maximum admissible pollutionlevels (MAP) for agricultural uses; and

(viii) By 2015, define water-relatedcomponents of a strategy that willimprove food supply chain efficiencyby 50 percent and promotesustainable diets, including steps forits implementation by 2025.

For each of the Targets, a Target andSolutions Group has been formed. ICID isthe coordinator of the Target and SolutionsGroups III – Jacques Plantey and BartSchultz, and for the Group V - Pres.Chandra Madramootoo. A BackgroundNote has been made that was recentlyupdated, based on the latest decisions.There are draft descriptions of the Targetsand a Metaplan showing the provisionalcomposition of the Core Group and thedifferent Target and Solution Groups. Therevised Background Note and the Metaplancan be viewed at <http://www.icid.org/wwf6/wwf6_bg_note.pdf>.

During the coming period, the Target andSolution Groups are expected to makeaction plans and to compile an overviewof interesting solutions. In addition, basedon the Background Note and the other

documents, a report on theThematic Priority as well as aprogramme for the sessionswill be prepared. The sessionswill be based on the Targets.All relevant documents will beposted on the ICID websiteas well.

Within ICID, the Task ForceWWF6 is coordinating thedifferent activities in closecooperation with Central Office.During the meetings inYogyakarta, Indonesia, Orleans,

France and Groningen, the Netherlandsspecial sessions have been held on WWF6.During the Congress in Tehran there willalso be a Special Session on WWF6.

We hope that in this way we can present astrong case on the optimal use of water forfood security. Any additional input from allwill be most welcome.

In 2009, Tehri Dam received an ICOLDAward as an International Rockfill Dam

Milestone Dam. An earth and rockfillstructure, Tehri Dam is 260.5 meters highand is located on the Bhagirathi River inthe Himalayan Mountains northeast ofNew Delhi, India. Construction began in1978 and was completed in 2006. Theconstruction cost was about US$1 billion.Tehri Dam Project is a joint venture of theGovernment of India and the state of UttarPradesh. The Central Water Commission(CWC) in New Delhi was the Project CivilWorks Design Consultants.

The reservoir created by Tehri Dam has alive capacity of more than 2.6 billion cubicmeters (3.54 billion cubic meters as gross).The multi-purpose project includes peakinghydropower, water for irrigation and watersupply for several rural and urban area,including India’s capital city of New Delhi,and flood control. In addition to thestabilization of 604,000 hectares ofexisting irrigable areas, about 270,000hectares will receive water for additionalirrigation; 270 million gallons per day ofdrinking water will be provided for bothrural and urban needs.

The Tehri Dam powerplant currently has1,000 MW capacity, and in the Stage IIPumped Storage Plan, an additional 1,000MW of capacity will be installed. With therecent completion of the downstreamKoteshwar Dam, the Tehri HydropowerComplex will add an additional 400 MWof capacity to the grid. Last January, I hadan opportunity to visit Tehri Dam andPowerplant and Koteshwar Dam, accom-panied by Engineer M. Gopalakrishnan,the Secretary General of the International

Commission on Irrigation and Drainage.Gopalakrishnan was a design engineer withthe CWC and was directly involved withdesign of Tehri Dam features. He provedto be an excellent guide, showing me anumber of features of the dam includingsome novel concepts, like galleries throughthe core of the embankment dam, and twoshaft spillways, 12 meters in diameter andnearly 200 meters deep, each handlingflows of about 1,900 m3/sec. The shaftspillways augment the chute spillwaywhich can handle about 5,500m3/sec. Wevisited the Tehri Dam Powerplant, whichwas constructed in the hill side on the leftabutment of the dam, since there was notenough room in the canyon below thedam to include the Powerplant. I was quite

impressed with Tehri Dam and powerplant,noting especially the high level ofmaintenance. We also visited the underconstruction Koteshwar Dam. We watchedas the diversion tunnel gates were beingclosed, an unique opportunity to see thenewly completed upstream dam face —project engineers told us that the re-regulating reservoir, just downstream fromTehri Dam, would fill within three days.The highlight of the Tehri Dam trip wasthe opportunity to visit the office of R.S.T.Sai, Chairman and Managing Director ofTehri Hydro Development Corporation Ltd.He was obviously proud of the Project andthe ICOLD recognition. The award isprominently displayed in his office.

My India visit included a very positivemeeting with the Indian Committee onLarge Dams. We discussed the USSD bidto host the 2013 ICOLD Annual Meetingand INCOLD’s plans to bid for the 2014Meeting. I reviewed USSD preparatoryactivities and showed the video wepresented during the 2010 ICOLD Meetingin Hanoi. The INCOLD officials were quitesupportive of our plans to host in 2013;they suggested that INCOLD and USSDmake plans for a MoU to further technicalexchanges between the two NationalCommittees.

Globally, 80% (1.25 billion ha) ofarable land is rainfed with varying

importance with the region (95% in sub-Saharan Africa, and 60% in South Asia)and produces most food for poorcommunities. These areas are the hot-spotsof poverty, malnutrition, severe waterscarcity, prone to severe land degradation,and have poor infrastructure.

Agriculture is the world’s second largestconsumer of the water after the forestry,and is also a cause of depleting soilquality. Growing need to produce morefood, feed as well as biofuel for energymeans increasing pressure on scarce waterand land resources. Simultaneously, the percapita availability of land and freshwaterhas been declining since 1950 due toincreased human population These inter-linked and multiple challenges can’t besolved with business as usual approach,without enhancing the efficiency of water,land and other natural resource use,without crossing the safe operating spacefor the humankind.

The current global population that has bluewater stress is estimated to be 3.17 billionand expected to reach 6.5 billion in 2050.If both green and blue water are consi-dered, the population currently experien-cing absolute water stress is only a fractionof projected (0.27 billion), and will onlymarginally exceed today’s’ blue waterstressed in 2050. Large parts of China,India, and sub-Saharan Africa areconventionally water scarce, but still havesufficient green and blue water to meet thewater demand for food production.

Large yield gaps with farmers’ yieldsbeing about 2 to 4 times lower than theachievable yields for major rainfed cropsare observed in Asia, Africa and CWANA(Central and West Asia and North Africa)regions. There is an urgent need todevelop a new paradigm for upgradingrainfed agriculture and the business asusual approach can no longer achieve thegoal of food security. Vast scope exists tounlock the potential of rainfed agriculturethrough sustainable management of naturalresources through integrated watershedmanagement (IWM) approach. The IWMapproach provides a framework for

unlocking the potential of rainfedagriculture to improve livelihoods throughknowledge-based and participatory methodfor sustainable intensification withincreased efficiency of natural resource use.

The ICRISAT-led consortium developedan innovative farmers’ participatory IWMconsortium model that espouses theintegrated genetic and natural resourcemanagement (IGNRM) approach where

For the greater part of the world, water stress is primarily a blue water issue, and large opportunities exist in the management ofrainfed areas, i.e., the green water resources in the landscape. Dr. Suhas P. Wani, Principal Scientist (Watersheds) and ProjectCoordinator (IWMPs), Resilient Dryland Systems, International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Indiaexplains as how an integrated watershed development approach can increase the crop yields 2 - 4 times in rainfed areas.

activities are implemented at thelandscape level. The entire process revolvesaround the four E’s (empowerment, equity,efficiency and environment), which areaddressed by adopting specific strategiesprescribed by the four C’s (consortium,convergence, collective action andcapacity building).

The IWM consortium model has producedmultiple benefits such as increasing cropproduction by 2 to 4 folds, doubling of thefamily incomes, increasing groundwateravailability, reducing runoff to less thanhalf and soil loss by 1/7th, conservingbelowground and above-ground bio-diversity, building social and institutionalcapital in the benchmark watersheds inIndia, Thailand, Vietnam, China andPhilippines. The Integrated WatershedManagement approach in Kothapally isrevolutionalizing agricultural productivityand incomes. The crops yields haveincreased by two to four folds as comparedto the best land crop yields and havebridged the yield gap substantially.

The scaling-up of the IWM is taken upby the Government of India and othercountries in Asia. Through South-Southcollaboration, the IWM approach is beingevaluated in southern and eastern Africathrough ASARECA (Association forStrengthening Agricultural research inEastern and Central Africa).

Dr. Suhas Wani can be contacted at<[email protected]>.

Important components of theICRISAT’s New Model

• Collective action by farmers and theirparticipation from the beginning throughcooperative and collegiate mode in placeof contractual mode. Participatory researchand development (PR&D) approach.

• Principle of “users pay”, no free rides inthe program.

• Demand-driven approach, and no supplydriven technologies.

• Integrated water resource management andholistic approach for improving livelihoods.

• A consortium of institutions for technicalbackstopping.

• Knowledge-based entry point to buildrapport with community and enhancedparticipation.

• Tangible economic benefits to individualsthrough on-farm interventions enhancingthe efficiency of conserved soil and waterresources and targeted income generatingactivities for women and vulnerable groups.

• For equitable benefits to small farmers, low-cost and environment-friendly soil and waterconservation measures throughout the topo-sequence.

Of the 300 million ha of irrigated landin the world, some 113 million ha

presently depend on groundwateraccounting some 25% of the total irrigationwater withdrawals. The overall groundwaterextraction has gone up from 100 millionkm3 in 1950 to about 1000 km3 in 2000.Of which 70-75% extraction goes foragriculture. It is estimated thatgroundwater-based systems generate$210–230 billion of revenue and areeconomically and socially more efficientthan surface water systems. The low costsof installing and operating tubewells alongwith the resulting groundwater revolutionhave been the main reasons for this rapidgrowth. Groundwater irrigation covers themajor irrigated area in France; half of theirrigated areas in South-Asia and is crucialin North-Africa. But, unlike surface water,groundwater is not easily measurable andmanageable. In most cases it is used bya large number of independent users,including farmers, who have direct accessto water. The same goes for diffusepollutions. The complexity of aquifersfunctioning on large time and space scaleshampers collective action as well as theperception of the impacts on theenvironment.

Despite these challenges, ICID so far hasnot focused enough on issues related togroundwater. The Conference hosted byAFEID is therefore of significance. TheBeauce region is an important region forgrain production in France. Here farmershave tested an innovative volumetricmanagement system to manage thegroundwater. A return from experienceby stakeholders and users of the Beaucegroundwater was presented and discussed.

President Madramootoo in his keynoteaddress spoke on global trends in theusage of the groundwater reserves andresulting pressures from overexploitation.Dr Margat, a world-renowned hydro-geologist presented key data on the usageof the groundwater for irrigation, noting itsrapid development during the past 50 yearsand the difficulties in managing acollective resource for which thousands ofindividuals have liberal access. Pr Ghislainde Marsily, an eminent hydrologist andmember of the French Academy ofScience, presented a case study on aquifermanagement in the French region of

Marais-Poitevin whichcalls into question thenecessity for extensiveknowledge of waterresources for its manage-ment. Dr. Marcel Kuper,on behalf of Dr. T Shah,senior fellow at IWMIdescribed howcommunities in Indiahave responded toaquifer development andoverexploitation, notingtwo distinct responsesbased on the abundanceand accessibility of waterresources. Pr B Barraqué,political scientist andeconomist with theFrench CentreInternational deRecherches sur l’Environnement et leDéveloppement, described the evolution ofwater management in Europe, as the statusof groundwater resources move from athing that is privately owned to a commonresource under Public Trust.

• Irrigation withdrawals are causing theimbalance of groundwater in theMediterranean region. The groundwaterquality has deteriorated due to veryhigh nitrate concentrations (sometimeshigher than 400 mg/l).

• While conjunctive use of groundwaterin irrigated schemes is desirable, it canalso be the source of new inequitiesbetween those who can invest in aborehole and other farmers. It wouldtherefore be important to know if acollective appropriation of groundwaterand its management is appropriatethrough allowance policy, collectivedrillings.

• There are a few cases of successfulgroundwater management implemen-tation and also a few cases ofuncontrolled “tragedies of thecommons.’’

• The Water Framework Directive 2000/60/CE (WFD) requires Member Statesto protect, enhance and restore waterswith the ultimate objective of achieving“good status” for both surface andgroundwater bodies. While “good

quantitative status” is clearly defined inthe WFD, this is not the case for thecomplex “good chemical status.” So thelessons learned in the last 10 yearswere presented.

• Economic approaches of groundwatermanagement discussed were (i)dynamics of, economic activities andgroundwater resources, (ii) assessingand comparing the economic cost and/or benefits of different groundwatermanagement options, and (iii) designingand testing groundwater regulationinstruments such as prices, (abstraction/pollution) charges or taxes and marketsof water rights.

• Groundwater pollution is not only theresponsibility of agriculture with ahighly variable ratio betweenagricultural/non-agricultural pollutionsources, but also other users. It is thusnecessary to involve all the parties tofind solutions at the local scale. Thetypes of action (preventive like localarrangements between water suppliersand groups of farmers or curative likewater treatment or alternative resource)should be analysed in context totechnical and economic criteria.

What Does Efficient Irrigation Really Mean?What Does Efficient Irrigation Really Mean?What Does Efficient Irrigation Really Mean?What Does Efficient Irrigation Really Mean?What Does Efficient Irrigation Really Mean?The South African National Committee hosted the 2010 SANCID Symposium in Upington in the Northern Cape. The theme forthe symposium was “Efficient water use for food production.” A total of 26 papers were presented on sub-themes of irrigationscheduling, soil nutrient management, irrigation strategies, water management at catchment scale, irrigation efficiency, waterproductivity and modelling water use. Dr Richard Stirzaker, Principal Research Scientist, CSIRO, Canberra was the keynotespeaker and gave a very interesting presentation on the perception of efficient irrigation. He conveyed the following message tothe delegates:

Depending on how you look at things,the task of feeding the world in 2050

can seem hopeless. Population increases at200,000 individuals per day, water suppliesare diminishing, land is degrading, food isdiverted to biofuels and diets are changingto consume more water per person. Canwe really double food production whenthe macro indicators are all going in thewrong direction?

But if you look at the business of turningwater into food step by step from the smallscale upwards, things might not look quiteso bleak. Let’s start with 100 liters of waterin the dam, which we want to turn intofood on a farm. When the water isdelivered to the farm through open unlinedchannels, 20% of the water can easily belost through evaporation and channelleakage before reaching the farm gate. Onreaching the farm, the water may be storedin a small dam before being moved aroundthe farm in earthen canals. Evaporationfrom the dam and leakage from the farmcanals means only 70% of the remainingwater reaches the edge of the field.

Then we apply this water to the crop byflooding the field. Sometimes water runsoff the far end of the field and it iscommon for more water to infiltrate intothe top end of the field and drain belowthe roots. We may only get 60% of theavailable water into the root zone, ofwhich 50% evaporates from the soilsurface. Do the calculations - (0.8% x0.7% x 0.6% x 0.5%) and we see only17 liters of our original 100 liters aretranspired by the plant.

There are several points here where wecan intervene. Let’s suppose we can get95% of the water to the farm gate andpipe the remaining 95 liters of wateraround the farm to each field, again at95% efficiency. Five more liters are lostsomewhere on the farm and the remaining90 liters reaches the sprinklers in the field.We manage to get 85% of the 90 litersstored in the root zone, leaving 77 litersavailable for the crop to use of which 65%of the water was transpired and 35 %evaporated. The amount of water used bythe plant is now 65% of 77 liters, or 50liters (0.95% x 0.95% x 0.85% x 0.65%)

of the 100 liters that left the dam. Movingfrom a poor system to a better one cangive us three times the amount of usefulwater – from 17 to 50 liters. There is acaveat here because not all theinefficiencies result in a net loss of water.Water draining below the root zone ofcrops reaches the ground water and mayfind its way back to the river, or bepumped up and reused by anotherirrigator.

A well grown crop can produce 1 kg ofgrain from a thousand liters of water,whereas a poorly grown crop would beunlikely to be one third as productive. Wehave seen above that we can increase thewater transpired three times (from 17 to 50liters) and with the right kind of investmentin farmer training and support we couldincrease the crop productivity of waterthreefold as well. Putting the engineeringand the biological sides together gives us3x3 or a nine fold improvement. This isnot to say that the ninefold increase iseasily attainable – just that it is withinreach and is in fact being achieved in bitsand pieces all over the world. The questionis ‘why do we not learn much faster?’

In order to achieve higher water useefficiency, new technologies must becoupled with the development of new

institutions that are capable of managingwater effectively. It is necessary to useadaptive management to deal with thecomplexity by involving professionals frommany disciplines and through the processof ‘learning by doing.’ Which in turn shallbe based on simple monitoring programsthat include observation, evaluation, andrevision of decisions and projections tosustain continuous improvement of wateruse efficiency in agricultural systems.

When we look again at the big picture,the need for new institutions and a trans-disciplinary approach to managing water atappropriate scales is clear. But at the otherend of the spectrum, many small bygains can be made through systematicapplication of adaptive learning, based onthe use of simple tools. Some examples ofthis in practice can be seen at http://www.thescientistsgarden.com and at http://www.youtube.com/watch?v=Cyj6BzdUllI.To double food production by 2050, wewill have to double our efforts at bothends of the water management spectrum.

Globally, 80% (1.25 billion ha) ofarable land is rainfed with varying

importance with the region (95% in sub-Saharan Africa, and 60% in South Asia)and produces most food for poorcommunities. These areas are the hot-spotsof poverty, malnutrition, severe waterscarcity, prone to severe land degradation,and have poor infrastructure.

Agriculture is the world’s second largestconsumer of the water after the forestry,and is also a cause of depleting soilquality. Growing need to produce morefood, feed as well as biofuel for energymeans increasing pressure on scarce waterand land resources. Simultaneously, the percapita availability of land and freshwaterhas been declining since 1950 due toincreased human population These inter-linked and multiple challenges can’t besolved with business as usual approach,without enhancing the efficiency of water,land and other natural resource use,without crossing the safe operating spacefor the humankind.

The current global population that has bluewater stress is estimated to be 3.17 billionand expected to reach 6.5 billion in 2050.If both green and blue water are consi-dered, the population currently experien-cing absolute water stress is only a fractionof projected (0.27 billion), and will onlymarginally exceed today’s’ blue waterstressed in 2050. Large parts of China,India, and sub-Saharan Africa areconventionally water scarce, but still havesufficient green and blue water to meet thewater demand for food production.

Large yield gaps with farmers’ yieldsbeing about 2 to 4 times lower than theachievable yields for major rainfed cropsare observed in Asia, Africa and CWANA(Central and West Asia and North Africa)regions. There is an urgent need todevelop a new paradigm for upgradingrainfed agriculture and the business asusual approach can no longer achieve thegoal of food security. Vast scope exists tounlock the potential of rainfed agriculturethrough sustainable management of naturalresources through integrated watershedmanagement (IWM) approach. The IWMapproach provides a framework for

unlocking the potential of rainfedagriculture to improve livelihoods throughknowledge-based and participatory methodfor sustainable intensification withincreased efficiency of natural resource use.

The ICRISAT-led consortium developedan innovative farmers’ participatory IWMconsortium model that espouses theintegrated genetic and natural resourcemanagement (IGNRM) approach where

For the greater part of the world, water stress is primarily a blue water issue, and large opportunities exist in the management ofrainfed areas, i.e., the green water resources in the landscape. Dr. Suhas P. Wani, Principal Scientist (Watersheds) and ProjectCoordinator (IWMPs), Resilient Dryland Systems, International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Indiaexplains as how an integrated watershed development approach can increase the crop yields 2 - 4 times in rainfed areas.

activities are implemented at thelandscape level. The entire process revolvesaround the four E’s (empowerment, equity,efficiency and environment), which areaddressed by adopting specific strategiesprescribed by the four C’s (consortium,convergence, collective action andcapacity building).

The IWM consortium model has producedmultiple benefits such as increasing cropproduction by 2 to 4 folds, doubling of thefamily incomes, increasing groundwateravailability, reducing runoff to less thanhalf and soil loss by 1/7th, conservingbelowground and above-ground bio-diversity, building social and institutionalcapital in the benchmark watersheds inIndia, Thailand, Vietnam, China andPhilippines. The Integrated WatershedManagement approach in Kothapally isrevolutionalizing agricultural productivityand incomes. The crops yields haveincreased by two to four folds as comparedto the best land crop yields and havebridged the yield gap substantially.

The scaling-up of the IWM is taken upby the Government of India and othercountries in Asia. Through South-Southcollaboration, the IWM approach is beingevaluated in southern and eastern Africathrough ASARECA (Association forStrengthening Agricultural research inEastern and Central Africa).

Important components of theICRISAT’s New Model

• Collective action by farmers and theirparticipation from the beginning throughcooperative and collegiate mode in placeof contractual mode. Participatory researchand development (PR&D) approach.

• Principle of “users pay”, no free rides inthe program.

• Demand-driven approach, and no supplydriven technologies.

• Integrated water resource management andholistic approach for improving livelihoods.

• A consortium of institutions for technicalbackstopping.

• Knowledge-based entry point to buildrapport with community and enhancedparticipation.

• Tangible economic benefits to individualsthrough on-farm interventions enhancingthe efficiency of conserved soil and waterresources and targeted income generatingactivities for women and vulnerable groups.

• For equitable benefits to small farmers, low-cost and environment-friendly soil and waterconservation measures throughout the topo-sequence.
