  • Vale do Tonosí Irrigation and Training Project

    The Vale do Tonosí Irrigation and Training Project Viability study and Final Drawings cannot be approached as an individual works, but as having the potential to fully develop the whole region in question. In addition to deterring the flooding of the vale, situated in the Los Santos region of Panamá, the studies seek also to promote energy production, implant water collection and sewage systems and to create new rural possibilities thus promoting social development of the population and guaranteeing the future sustainability of the venture.

    As general coordinator of the activities developed we have undertaken both technical and viability studies in order to complete the final phase of the project: around 2,500 ha within the Vale de Tonsí. We elaborated a diagnosis of the current socio-agro-economic situation and the physical aspects of the affected region in addition to a preliminary environmental evaluation. At a later stage the complete development plan will be elaborated together with preliminary drawings of the works.

    Michoacán State Hydro Agriculture

    Odebrecht was hired by the Michoacán State Government in Mexico to provide a solution for the hydric shortage in the Lázaro Cárdenas hydro-agricultural perimeter. We undertook hydrological studies to determine the hydric availability of two rivers in the region. We also conceived and wrote the initial project draft of a dam and a canal to transport water from where it is captured to the irrigated perimeter.

    We are currently developing the executive project and supporting the implementation of the [water transportation] canal works, which is scheduled to be completed in 2010 and which will have an outflow of 12.5 m3/s and an extension of 35.5km. The project presents important engineering challenges given the topographic and geotechnical conditions.

    El Diluvio-Palmar

    In expanding our activities beyond Brazilian boarders we participated in an important irrigation project in a 20,000 ha area in the Maracaibo plain in Venezuela. The El Diluvio-Palmar irrigation system is made up of a dam which supplies a water main connected to a main canal that transports water at an outflow of 11.4m³/s and to a low-pressure water distribution network, which supplies all 240 lots involved in the project.

    The work done involved developing the basic project for new primary, secondary and tertiary mains in addition to undertaking topographic and geotechnical studies of the network. Following this the network and work’s executive project was executed, as was the project to measure control outflow from the dam to the lots.

    Remigio Rojas

    The Remigio Rojas irrigation project covers a 3,200 ha area situated in the Chiriqui province in Panamá, a traditionally rice-producing region. Through this project the Panamanian government intends to development, exploit and export products which have a higher value, such as fruits.

    Our role in this is to train and organise the users in managing the project. This includes operating and maintaining the irrigation infrastructure and managing livestock production in planning and providing agronomic technical support and support for post harvesting and marketing efforts.

    This includes operating and maintaining the irrigation infrastructure and managing livestock production in planning and providing agronomic technical support and support for post harvesting and marketing efforts.

    The project foresees construction of a dam in the river Chico in the Alanje district in Panama. The dam will make it possible to supply water for rice production, which constitutes 70% to 80% of the area located approximately 12 km for the Interamericana highway, close to the border with Costa Rica. With the building of the waterways and distribution canals the intention is to introduce new crops for the purpose of exporting and guaranteeing the region’s sustainability.

    The work is comprised of three distinct phases. The first phase consists of developing and implementing the training programme, as well as transferring technology for operating the irrigation system. Subsequently, there is monitoring and support during the initial operating phase of the system. The final phase of the project is when the marketing and sales strategy is implanted. This will allow participants to develop and manage markets and to implement innovative marketing efforts in addition to setting up a credit fund.

    New Irrigation Model

    The New Irrigation Model study is composed of a series of analyses aimed at establishing the necessary directives to implement the desired changes in the Brazilian Northeastern Irrigation Model. We used a multiple approach method regarding agricultural practice in Brazil and the Northeast with a view to presenting a description of the agricultural sector and statistics related to it. Another aim was to raise issues for discussion on the role of irrigation in agriculture, as well as public and private intervention in irrigation processes.

    As such we conceived the proposal for the new model concept, covering technical, economic, financial, environmental, legal and management viability alternatives. Finally, we applied the directives for the new model to the Salitre project in the Petrolina-Juazeiro cluster.

    Terra Nova

    The Terra Nova venture’s basic commitment was to eliminate the chronic poverty in the São Francisco river basin region and also that in the Northeastern semi-arid region. To do so we adopted an integrated strategy for sustainable development. The project was developed in three stages starting in 1997 and ending in 2006.

    In the initial stage of the project we conducted a physical, environmental and socio-economic diagnosis of the region. We organised the data collected into thematic reports which allowed us to zone and classify the area by its development potential.

    The second stage covered the studies, characterised the different potential and sought to minimize conflicts identified through multiple-use alternatives. All in all, we studies three alternatives for building a canal from the Sobradinho reservoir and other locations along the São Francisco river.

    Concluding the final phase we evaluated the interfaces with the Canal Sertão Pernambucano and the IV Stretch of the São Francisco river transposition. In this phase we also reevaluated previous demand and operational studies, ending with an analysis on environmental impacts and an economic, financial and social evaluation.

    Salitre PPP

    Located in Juazeiro, Bahia, the Salitre project is on a public irrigation system covering an area of 30,000 ha. At the time the study was conducted the first stage was implanted and encompassed an area equivalent to 5,000 ha.

    The study aimed to identify an alternative which would make it possible to provide continuity for the project by way of a concession in a public private partnership. As such, we developed a proposal for the implementation, operation and maintenance of the infrastructure, as well as a model to take advantage of agricultural opportunities that justify the investment and adhere to all environmental requirements.
