EurAgEng SIG on Soil and Water Activity
The Valenzano Statement
Conclusions and Recommendations of the International Conference on "Water Management, Salinity and Pollution Control toward Sustainable Irrigation in the Mediterranean Region" , Valenzano (Italy) 22-26 September 1997
The Conference was organised by the Mediterranean Agronomic Institute of Bari, with the help of the World Water Council, Section I of the Italian Society of Agricultural Engineering and the EurAgEng Special Interest Group on Soil and Water.
The Conference attracted 156 participants from 30 countries, 15 of which are of the Mediterranean basin. Several key officials attended the Conference including the Ministers of Agriculture of Albania and Malta, representatives of the European Union (EU), World Bank (WB), International Commission on Irrigation and Drainage (ICID), World Water Council (WWC), International Centre for Agricultural Research in Dry Areas (ICARDA), International Fund for Agricultural Development (IFAD), United Nations Development Programme (UNDP) and United Nations Food and Agriculture Organization (FAO).
A total of 119 papers were presented, 96 in 12 plenary sessions and 23 in the poster sessions. They covered the following topics:
- Water Quality and Pollution Control
- Water Resources and Irrigation Water Management
- Wastewater Re-Use in Irrigated Agriculture
- Capacity Building and Water Quality Management
- Fertilisers and Water Quality.
Several special sessions were also organised parallel to the main themes of the Conference addressing specific topics.
At the Closing Ceremony the following considerations have been pointed out:
Subject 1 - Water Quality and Pollution Control
(With contributions from D. De Wrachien and R. Van Genuchten)
The session noted the alarming rate of increase in water scarcity and water quality deterioration around the world and especially in the Mediterranean region.
In spite of large studies made for better understanding soil, soil-water-plant and pollutants interactions, knowledge is still lacking in many key areas. Better understanding of the unsaturated flow using non-equilibrium thermodynamics and other approaches can be useful.
Models can be useful tools to predict and provide better understanding of the physical, chemical and biological aspects of salt movement in cropped and salt-affected soils.
Crop tolerance to salt and related mechanisms are needed for better design and management of irrigation systems.
The session concluded that:
- Much expertise, both basic and applied, exists on salinity and groundwater pollution issues in the different countries surrounding the Mediterranean, as well as elsewhere. It is imperative that interaction between individual research and extension groups within the Mediterranean and other countries be encouraged as much as possible, perhaps through CIHEAM/IAM-FAO. This interaction should involve co-operative research, education and sharing of computer codes, specific databases or other information or research expertise deemed useful for addressing salinity and water pollution problems.
- There is a wide scope for research and development in the following areas:
- scale dependence of soil physical properties and processes
- upscaling of soil information
- preferred pathway for water and solute flow phenomena
- parameter identification and the optimal use of simulation models for studying the dynamics of degradation of chemicals in soils
- flux measurements in the unsaturated zone
- soil-rhizosphere interactions.
Subject 2 - Water Resources and Irrigation Water Management
(With contributions from R.A. Feddes and A. Hamdy)
This session highlighted the following issues:
- There is not enough fresh water in the world to meet agricultural requirements. It is expected that by the year 2050 2/3 of the world will face an intolerable situation of water shortage if the present rainfall pattern prevails and if no proper actions are taken to save water, minimise water losses and improve water management. Therefore, a number of actions should be considered:
- Reducing wastewater in irrigation systems, better management, developing more drought and salt tolerant crops
- Eradicate salinity and water logging
- Improve drainage and flood control systems
- Broadening the education system so that multidisciplinary systems meet the new and complex challenges
- Enhance the capacity of Research and Development known as R&D
- Broadening the role of stakeholders
- Adopting an integrated water management approach.
- Managing water quality needs:
- Water quality assessment
- Water source protection
- Efficient irrigation water management and salinity management
- Water table management
- Management and disposal of saline water.
- Developing and application of mathematical models.
It is recommended that the use of mathematical models should be encouraged. Models should represent actual processes and account for the heterogeneity of the system. It should also account for temporal and spatial variability. In that respect, steady state drainage criteria are insufficient to describe processes such as aeration, sub-irrigation, leaching and capillary rise. Dynamic simulation models of water flow and solute transport in the saturated and unsaturated zones in combination with carefully selected field experiments are crucial instruments for proper water management, salinity and pollution control towards sustainable irrigation. In addition, the use of dynamic simulation models is more important to assess the consequences of "what if scenarios" in terms of relative impact rather than absolute values.
Subject 3 - Wastewater Re-Use in Irrigated Agriculture
(With contributions from A. Hamdy and R. Ragab)
This session highlighted a number of issues related to irrigation, drainage, crop and soil management, environment protection and health safety. The following recommendations were reported:
- Generally, the use of saline water for irrigation requires a selection of appropriate salt tolerant crops and an improvement in water management and maintenance of soil physical properties to ensure adequate soil permeability to meet leaching requirements.
- Better techniques to determine optimum leaching requirements for dynamic situations are needed. There is a gap in present knowledge on how plants respond to salinity stress that varies with time and space. Most of the present knowledge on water and solute flow is for deep groundwater table conditions. The specific effect of various salt constituents on crops is not well understood. Periodic information on salinity is required, i.e. inventories, data base systems.
- More information and dynamic models are needed to show how crops respond to time and space varying osmotic and matrix stresses as a function of irrigation management, soil water retention characteristics and atmospheric stresses.
- Integrated approaches are needed to facilitate the use of saline water for irrigation, to minimise drainage disposal problems and to maximise the beneficial use of multiple water sources.
- More investigation is needed on the long-term effect of irrigation with saline water on soil and vegetation (trees). This can only be achieved by conducting long-term experiments. More investigation is also needed on the long and short-term effects of irrigation with wastewater on soil and vegetation and human health.
- The safe disposal of highly saline drainage water requires a good balance between environmental protection and the economy factor.
Subject 4 - Capacity Building for Water Quality Management
(With contributions from A. Hamdy and A. Shady)
Capacity building has become a critical requirement for improving water management practices in the future. The current attempts to enhance capacity are a useful beginning, but they suffer from numerous conceptual and operational constraints. Unless these constraints are objectively identified, and the entire process is carefully planned to overcome these problems promptly and cost-efficiently, benefits that are likely to occur from such efforts would be at best incremental.
However, if planned and implemented properly, capacity building has the potential to contribute to a quantum leap in water management during the early part of the 21st century.
Capacity building is analogous to capital, the more it is properly spent, the more output is yielded.
There is mounting evidence that, in the near future, the major constraint to water resources development and protection will be the limited capacity of the institutions in many countries to absorb financial resources and convert them into worthwhile and sustainable development.
Capacity building has been identified as the missing link in water resources development and management. Many failures in water resources management are the result of lack of trained staff and weak institutions.
Capacity building and its successful implementation by local-level management institutions still require answers to the following related questions:
- What are the factors producing successful institutional functions at local level?
- How can farm-level institutions be integrated into the irrigation institutions operating at regional and national levels?
- What are the legal and institutional arrangements needed to promote more effective farmers’ organisations?
- What are the functions best carried out by local groups, and how can they be reinforced?
- What are the incentives needed to promote active member participation in water user’s groups?
Subject 5 - Fertilisers and Water Quality
(With contributions from A. Hamdy and I. Papadopoulos)
The session highlighted the usefulness of the Agri-Screen Decision Support System to predict probable range of off-site pollution from agricultural fertilisation. Modelling techniques can be useful in predicting fertiliser movement in soil and water. These techniques would show the critical impact on groundwater quality and the extent of its vulnerability.
In this respect, proper irrigation techniques are expected to minimise off-site effects of fertilisers.
A number of issues have been raised:
- There is a need to define new management practices to improve fertiliser use efficiency, minimising leaching into groundwater both in humid and dried regions. This issue includes selection of optimum:
- fertilisation (rate, type, form and time of application)
- irrigation and drainage
- surface cover / residues
- plant species
- waste disposal.
- Developing Integrated Plant System (IPS) of nutrient management is crucial to enhance nutrient use efficiency. Systems with low nutrient use efficiency have most drastic adverse effects on water quality. Not only should the nutrient losses by runoff / erosion and leaching be decreased, but nutrient use efficiency should also be improved. Attention should be paid to soil and crop management systems that can be adopted to decrease losses. Best management practices (BMP’s) must be determined for integrated management of nutrient to enhance efficiency and restore losses.
- Micro-irrigation combined with fertigation technology present an alternative to the use of agro-chemicals under intensive farming conditions with minimum pollution hazards. Such system should be well designed, operated and maintained. There is a need to train extension workers and farmers for the successful use of such technologies. However, there is a need to device ways and means to leach and safely dispose the accumulated salts and chemicals even if they are in relatively small quantities to make such system sustainable.
Global Issues for Water Management
The Conference, during the Closing Ceremony, stressed that there is not enough fresh water in the world to meet agricultural requirements. Moreover, it is expected that by the year 2050 2/3 of the world will face an unbearable situation of water shortage if the present rainfall pattern prevails and the Mediterranean region will likely be one of the most affected areas in the world. With reference to this problem, care should be paid to the following:
- Sustainability of irrigated agriculture depends on better drainage for salinity control
- Water ethics should incorporate the obligations to protect the environment
- Management of natural water resources is to be based on holistic approach of comprehensive water resources management at the river basin level
- A multidisciplinary approach to studying water issues is more compatible with the complexity and diversity of the problem and the need to seek a comprehensive solution based on integrated water resources management
- Solidarity of the world is sought between the east and the west, and the south and the north in exchanging experience, transfer of knowledge and technologies on R&D, financing, peace and security
- There is much disappointment from the results of achievement of developing world water since Mar del Plata (Argentine) 1977. In spite of several UN sponsored meetings, a great deal of population has no access to adequate drinking water, sanitation, and millions suffer each year from floods and drought
- The world is facing a global crisis that requires a drastic change of attitude. New and creative solutions must be developed and implemented without delay
- Climatic changes in terms of rainfall, temperature and CO2 would drastically affect water resources and hence water distribution strategies
- Strategies for water management must consider how to safeguard water to meet basic human needs for different uses, minimise water losses, allocate scarce water for desired socio-economic objectives, protect the environment from degradation and loss of productive capacity
- Salinity is a major threat to sustainability of irrigated agriculture. Better management strategies and practices are to include adequate measures for leaching excess salts, reuse of drainage water, waterlogging control, proper disposal of drainage water, continuous monitoring of soil and water quality
- Saline water can be used for irrigation provided that an adequate drainage system is in place. In addition, leaching and disposal of salts should be considered
- Intermittent irrigation with fresh water is needed to maintain a healthy salt balance. Proper choice of irrigation application method is an important factor in a good management system. Moreover, scheduling, frequency of irrigation and selection of salt tolerant crops are essential elements.
Specific Recommendations for Future Actions
At the conclusion, it was recommended that consideration should be given to the following:
- The need to have a brainstorming session to unify the nomenclature related to the subject of "sustainability" and "pollution".
- To define common goals for future research and development, and establish priorities.
- As a follow-up to this Conference, another Conference or Workshop should be planned to present, discuss, and find solutions for case studies in the field of sustainable water resources and pollution prevention that are common in the Mediterranean countries.
- Formation of a MEDI-NET to exchange data, and promote co-operation among scientists from the Mediterranean countries.
- To establish a programme to improve the performance and increase the awareness of the end users in every sector of potential pollutant sector.

30th Session of the FAO European Commission on Agriculture
The 30th Session of the FAO European Commission on Agriculture (ECA) was held in Nitra, Slovakia from 8-11 October 1997.
At the beginning of the Session the situation in the agricultural and rural sector of Slovakia in a period of reforms and structural adjustment was introduced by the State Secretary of the Slovakian Ministry of Agriculture. He underlined the on-going changes involved in the process of reforming the private farm sector and resulting agrarian structures.
The current and future FAO activities in the European Region were supplemented by a number of room documents provided by the Secretariat of the ECA. The ECA was informed of the status of cooperation with the UN Economic Commission for Europe. The ECA took note of the fact that ECA remains the sole FAO technical body in agriculture of the region with pan-European membership. The activities of the Working Party on Women and the Agricultural Family in Rural Development, an ECA statutory body, were reviewed in detail. The ECA also reviewed the activities of the European System of Cooperative Research Networks in Agriculture (ESCORENA) on the basis of documents provided by the Secretariat, including a report of the European Research Network Advisory Committee (ERNAC). The ECA recommended that ESCORENA should take into consideration in the future also activities of global interest. New initiatives such as the Organic Farming Workshop (Rome, September 1997) and Biological Farming Research in Europe could be possible as future cooperation options. The FAO World Agricultural Information centre (WAICENT) was presented to the ECA. The ECA expressed interest and encouraged FAO to continue activities and services in this field.
The ECA was informed of the activities of the International Commission on Irrigation and Drainage (ICID) and of the activities of the Meteorological Organisation (WMO) related to European agriculture.
The main thematic paper ’Re-emergence of Pandemic Livestock Diseases in the European Region: an Assessment of Potential Impact’ was introduced by the FAO consultant. The paper outlined the present situation in which nine major epidemic diseases in livestock had occurred in the Region in recent years giving rise to economic losses of several billion dollars.
In the next thematic paper the issue of sustainable agriculture and research priorities was introduced. The debate centred around : 1) Institutional circumstances and barriers to agricultural growth and efficient research and extension, 2) the contribution of the European Region to easing problems of global food insecurity and 3) linkages between research and future growth of agricultural output and increased productivity. A strong recommendation was made for FAO to include research on organic and ecologically friendly farming in its programme. All academic and research communities face budget constraints and dilemmas of applied versus basic research. Advantages and dangers of private and public funding of research activities were discussed. In this regard the role of public research institutions also as controlling instrument was emphasised. The ECA recommended that FAO should follow up this new development.
The Secretariat provided the ECA with information and documents related to the World Food Summit (WFS) follow up with focus on activities of importance in the European Region.
The Secretariat also provided the Session with information on potential savings which could be achieved through the reduction of the number of working languages of the ECA.
At the end of the Session the ECA elected the new Executive Committee and the Permanent Representative of Georgia to FAO, on behalf of his government, invited the ECA to hold its
31st Session in Georgia. The Session requested the Chairman of the ECA and the Secretariat to convey this invitation to the FAO Director General for his consideration.
