Lake Chapala, Mexico: Integrating Sub-basins as an Integrated Lake Basin Management (ILBM) strategy Annual Review Meeting of the ILBM-Governance Project for FY2009 February, 23-25 2010 Ms. Cs. Alejandro Juárez-Aguilar MEXICO Location of Lerma-Chapala-Santiago Basin (Mexico) USA MEXICO Santiago River Basin Lerma-Chapala Basin I. Introduction: Lake Chapala and its basin. Lake Chapala is the largest natural lake in Mexico. Maximum storage volume: 7.897 Km³ Km³ Average surface: 1140 Km² Km² Media deep: 8 meters. Located in the middle of the Lerma RiverRiver-Lake ChapalaChapala-Santiago River basin (the most important and exploited in Mexico) Lake Chapala provides water to Mexico City and Guadalajara City (biggest Mexican cities, external users). 3 The Lerma-Chapala Basin Guadalajara City Mexico City •53591.3 km² •19 sub-basins Lerma-Chapala Basin Features Papelillo (Bursera spp.) Rural people Iguana (Ctenosaura pectinata) Corn (Zea maiz) Tropical dry forest Nopal (Opuntia ficus) VERTEBRATES BIODIVERSITY Source: INE, 2007. BASIN PROBLEMS • 552 dams in the basin (medium and large, one per 97 km2). •51% of dams are used for irrigation • Eutrophication and pollution (wastewater, agrochemicals, heavy metals). •Rivers’ water flow severed in long sections: riparian ecosystems strongly affected. LERMA-CHAPALA BASIN PROBLEMS Strong lake level fluctuations linked to hydric deficit of the basin (lake was reduced to 14.41% of maximum storage in 20012001-2002). 2002). Irrigation, stockbreeding and urban uses with low efficiency rates. Stockbreeding, industrial and urban uses produce high amount of pollutants. Agriculture generates N, P and runrun-off. Strong deforestation process (land use change). Highly spread erosion processes. SingleSingle-crop farming, minimum monetary gain for farmers, high ecological impact. Quarrels for water use: irrigation vs. urban users, conservation vs. Productive uses. Soil Degradation Dramatic dessication 1998-2002 Reduced to 14% of total volume in 2002 II.

The Sub-basin approach Priority sub-basins (all with working groups) November 2008 Workshop aspects: speakers 30 Workshop aspects 31 General Commitment to generate and operate a task network to maintain an exchange of data, share experiences and contribute knowledge in a rapid and effective manner. For the Santiago River watershed: Produce a guide of responsibilities and attributions of the institutions…in order to orient stakeholders on how to request information, facilitate decision-making and reduce conflicts. Support and encourage strengthening of CSOs internal structures. Draw up a list of research topics to avoid duplicity and overlapping… and assuring the practical application of research findings. For the Lerma-Chapala Basin: Create specific alliances to involve the different stakeholders in structuring and applying an action plan for the direct Lake Chapala sub-basin. Promote the creation of an Environmental Education Center in the Chapala-Jocotepec corridor and a center for documentary research. Organize an annual general meeting. Integrate a descriptive case study of Lake Chapala. ILEC assumes a commitment to promote the case of the Lerma-Chapala watershed as an ILBM focal point for Latin America. 32 ILBM Lerma-Chapala Basin Planning Workshop 2009 Morelia, City, December 3-4, 2009 •To follow-up national and international commitments to foster ILBM in Lerma-Chapala Basin. •To strengthen cooperative processes of institutions applying conservation, restoration and management projects in LermaChapala basin. •To foster analysis capabilities of federal, state and municipal government agencies, universities, research centers and civil society groups to develop and apply integrated management projects. •To create a common ground for applying ILBM in the LermaChapala sub-basins. 34 PARTICIPATING SUB-BASINS December, 2009 Workshop attendants 74 participants 37 institutions represented: 6 universities 5 federal agencies 12 state agencies 4 civil society organizations 3 multistakeholders groups 4 research centers 2 private groups 1 funding agency A) Overview on ILBM Finance Information Technology Policies Participation Institutions ILBM A Global Review of Lake Basin Management B) ILBM Process in Lerma-Chapala-Santiago Basin •A functional task network was created using ILBM as guidance. ILEC and INE worked as strong supporting institutions. •In the Lerma-Chapala level contacts with other sub-basins were established through INE’s workshop. •For Santiago River basin, CEDHJ integrated a macrorecommendation directed to 17 government agencies with very particular comments, asking answers by law about their projects and responsibilities for the river sanitation and ecological restoration. This recommendation was presented on February, 2009 being answered by 15 institutions which are complimenting their roles in different degree. •Lake Chapala Management Program is on-going process, within the Mexican Ramsar Sites program. It’s scheduled to be finished in March, 2010. It is being integrated by The Environmental Rights Institute (IDEA) and Corazon de la Tierra, with monitoring from SEMADES. 39 B) ILBM Process in Lerma-Chapala Basin (II) •A Center of Environmental Culture was opened in Chapala City in November, 2009, through a collaboration agreement between Corazon de la Tierra and the Water Commission of Jalisco State (CEA). One activity already organized was the Migratory Birds Festival for Lake Chapala, as part of a biggest initiative conducted by University of Guadalajara and SEMADES. •FIDERCO created the Water Information System for Central-Western Mexico, which includes both research papers available on internet and a researcher directory. It’s access free, directly in the webpage www.siarco.gob.mx •The Lake Chapala Brief is in preparation process, it will be feed with information from the Lake Management Program. •ILEC selected Lerma-Chapala watershed case as ILBM focal point for Latin America, which has been presented in the ILBM-Governance Meetings held in March, 2009 in Kusatsu, Japan; and in November, 2009 in Wuhan, China. •Finally, organizing this workshop fulfilled one of the commitment points.

Which would be the key factors to foster ILBM in your sub-basin? What common points can be identified between the analyzed sub-basins? Common conclusions Challenges: cooperative difficulties, nonnonintegrative approaches, lack of reliable information and funding; stakeholders’ stakeholders’ conflicts and lax regulations. Key factors: research (directed mainly to core topics and linked to decisiondecision-making process), monitoring, environmental education processes, access to information, creation and/or strengthening of management groups, structuring of tool boxes, manuals and guides; creation of finance mechanisms. Group Commitments Create an internet portal to have all case presentations and conclusions easily available. This was especially important given the huge amount of information received in short time. Time defined was February 2010 (first week). Open a virtual forum to discuss how workshop conclusions could be used to define a common working program linking the subsub-basins. Time for this goal was end of February, 2010. Group Commitments (II) Apply this working program in the particular sub-basins during the period March-October, 2010. Organize next workshop in Guanajuato State, having as core points to continue sub-basins strengthening and promote ILBM with other institutions.
