1 Making Conservation Public in Mexico: creating a National Public Lands Trust from scratch Paulo Quadri Barba PhD Candidate Environmental Studies Department UC Santa Cruz

2 Outline What is this about? Brief history and institutional context of land ownership in Mexico. Why create a National Public Lands Trust for Conservation. Using GIS for systematic conservation planning: Data Cartographic models Next Steps

3 About the project Initiative presented to the Ministry of the Environment (SEMARNAT) and the National Commission of Protected Areas (CONANP) in Objective Creation of a National Public Lands Trust in Mexico 1 st phase of project completed in 2015: technical and theoretical justifications and viability studies. Part of my doctoral dissertation project Today I will cover some aspects of how are we planning to use GIS for systematic conservation planning.

8 Why buy land for conservation? Only ~ 18% of Mexico s protected areas (PA) exist under public land ownership. The portfolio of conservation instruments is limited, relying mostly on stewardship agreements with landowners. Every year is more difficult to negotiate PA decrees. The supply of conservation as a public good is almost entirely dominated by private entities and thus is suboptimal. PAs does not seem to be providing poverty reduction benefits. Lack of Access to the majority of Mexican citizens and internationals.

9 Why create a National Conservation Land Trust? Economic, Demographic, and Forest Transitions

10 Why create a National Conservation Land Trust? 2 nd Land Reform Can t sell Ejido land 1992 Land Market Ejido Structure

11 How? Funding Carbon Tax + Private and International Donors Volume Tax per liter (MXN) Revenue (millones de pesos) Annual 45,700 liters ,743.6 Consumption of Gasoline a Annual 22,900 liters ,883.1 Consumption of Diesel b Total 68,600 liters 7,626.7 ~ $450,000,000 USD / yr

12 How Systematic Conservation Planning What is ecologically important? Biodiversity Approach What is socioeconomically important? Ecosystem Services Approach

13 Resources optimization approach Land value Willingness to sell Feasible to manage and protect (avoid open access conditions) Low conflict areas High local and national support (high public utility)

14 Relevant data available in Mexico Biophysical Data Socioeconomic Data Institutional Data Priority Attention Sites (CONABIO) Areas of Biological Priority Conservation status Distance to PA Deforestation Risk Topography and Soils (INEGI) Digital Elevation Models Edaphology Poverty and marginality (CONEVAL) Demographic Data (CONAPO) Land Tenure Data (RAN - PROCEDE) Land Production Value (INEGI) Payment for Environmental Services (CONAFOR) Agricultural Subsidies (PROCAMPO) Ranching Subsidies (PROGAN)

22 How much is society willing to pay for conservation? PES = Revealed willingness to pay of society for conservation ~ $1,000 MXN / ha / yr Using δ = 0.03 NPV = $33,300 MXN / ha ($1760 USD / ha) Alternative Use Annual Production per hectare Market Value per Unit (MXN) Total Annual Value per hectare (MXN) Net Revenue (total value costs of production) PROCAMPO o PROGAN 14 Net Present Value 12 Corn 1,000 Kg 1, , ,000 12, Extensive Cattle Ranching 43 Kg ,000 7, Chile (jalapeño) 1,500 kg , , , , Soy 4,000 K , , , , Sugar Cane 70,000 kg , , , , Temperate 1 m ,000 4, Forest Explotation 4 Peri-urban housing 13 NA m2 2,000,000 hectare NA NA 2,000,000.00

29 Willingness to sell Knight et al, 2010 and Guerrero et al, 2010 (South Africa): Demographics Human Capital Social Capital Years of ownership Years of farming Primary land use Number of generations property has been owned by family Land owner s cultural group Conservation knowledge (awareness of institutions) Conservation behavior (ecotourism, soil conservation, restoration) Willingness to be involved in conservation agreements Entrepreneurship Burn-out potential Local networks (memberships) Broader networks (municipality involvement)

30 Next Steps? Final approval of 2 nd phase of the project by the Ministry of the Environment COP, 2016 Identification of areas of high ecosystem services value beyond hydrologic services Pilot projects in the field: Test the model: how much slope and distance reduce municipality level production value? Field surveys to predict willingness to sell (Knight et al, 2010; Guerrero et al, 2010) Create a nationwide land price estimation layer and feed into an heuristic algorithm along with conservation priority data. Build a dynamic - adaptive optimization model.
