LECTURE 26 – Tropical Deforestation

Introduction

  • Overview of the detrimental impact of deforestation on tropical environments.

  • The focus will be on the trends observed in Latin America, especially the Brazilian Amazon, alongside the driving factors behind these changes.

Forest Cover Change in Latin America

  • Source of Data: Aide, M. et al. (2013). "Deforestation and reforestation in Latin America and the Caribbean (2001-2010)" published in Biotropica 45(2): 262-271.

  • Discussion on the shifts in forest cover observed across various countries in Latin America.

    • Dynamics of deforestation and reforestation over the monitored decade.

Causes of Deforestation

  • Identification and exploration of different factors contributing to deforestation.

  • Classification of Drivers:

    • Proximate Drivers: Immediate causes, e.g., agricultural expansion and logging.

    • Underlying Drivers: Broader socio-economic and political influences, such as governance and market forces.

  • Exploration of classic drivers affecting deforestation:

    • Population Growth: Increasing demand for land and resources.

    • Inappropriate Technologies: Tools and practices that are unsustainable or harmful to the environment.

    • Ill-defined Property Rights: Lack of clear ownership leads to exploitation of land.

    • Incomplete Markets: Absence of complete market structures inhibits sustainable land use.

    • Weak Institutions: Lack of enforcement of environmental regulations and policies.

Deforestation in the Brazilian Amazon

  • Historical context surrounding the opening of the Amazon from the 1960s to the 1980s.

    • Emergence of military government which influenced land policies.

    • Cultural Notion: "Land without people, for people without land" which driven state-sponsored settlement and agricultural practices.

    • Cattle Introductions: Developed as a primary agricultural focus due to government incentives.

Incentives Leading to Deforestation
  • Tax Exemptions: Offered on agricultural income which encouraged crop and livestock production.

  • Land Grants: Distribution of land to settlers promoted agriculture at the expense of forests.

  • Subsidies for Credit: Financial support directed towards agricultural production leading to deforestation.

  • Export-oriented Deforestation (1990s-2000s):

    • The rise of:

    • Cattle sector as a significant contributor to deforestation.

    • Soybean sector, which created pressure on forest land for agricultural production.

  • Discussion on the trend of falling rates of deforestation during certain periods.

Drivers of Deforestation in the Brazilian Amazon (1970s-80s)

  • Political Ideology (Military): Influence of government policies supporting agricultural expansion.

  • Economic Factors:

    • Vent for surplus issues leading to increased production of non-traditional exports.

    • Urban food inflation impacting agricultural decisions.

Beef and Soya Production in the Brazilian Amazon

  • Source of Data: Nepstad, D. et al. (2013). "Slowing Amazon deforestation through public policy and interventions in beef and soy supply chains" published in Science 344, 1118.

  • Examination of the relationship between beef and soybean production and deforestation events.

Falling Deforestation Rates in the Brazilian Amazon

  • Discussion on factors contributing to a decrease in deforestation rates:

    • Rise of democracy and civil society participation in environmental governance.

    • Focus on export-oriented pressures from key suppliers has led to moratoriums on soybean (2006) and beef (2009).

    • Government commitment towards climate change mitigation activities:

    • Setting targets to reduce deforestation and carbon emissions.

    • Notable initiatives like the Norwegian Climate and Forest Initiative and Bolsa Floresta program aimed at incentivizing conservation.

Indigenous Reserves and Other Protected Areas in the Brazilian Amazon

  • Source of Data: Boucher, D. et al. (2013). "Brazil’s success in reducing deforestation" published in Tropical Conservation Science 6(3): 426-445.

  • The establishment of indigenous reserves and their role in conservation efforts.

Deforestation Rates in the Brazilian Amazon

  • Analysis of historical deforestation rates correlating with changing political leadership:

    • Timeline: 2002 - 2023 annual deforestation patterns showing data from different presidential administrations.

    • Key figures represented in the context of square kilometers deforested:

    • Examples of administrations include:

      • Fernando Henrique Cardoso

      • Luiz Inácio Lula da Silva

      • Dilma Rousseff

      • Michel Temer

      • Jair Bolsonaro.

    • Note: Deforestation rates are subject to fluctuations based on policies and leadership.

Political Economy of Deforestation

  • Understanding the socio-political structure that influences deforestation:

    • Analysis of wealth distribution and its impact on deforestation practices.

    • Opportunities for capital accumulation driving the exploitation of natural resources.

    • Role of the state in enforcing or relaxing environmental regulations.

    • Impact of prevailing cost-price environments including currency devaluations.

    • International connections and markets affecting forest conservation and deforestation trends.

    • The rise of civil society in advocating for environmental protection and biodiversity conservation.
