Impact evaluation in a landscape: protected natural forests, anthropized forested lands and deforestation leakages in Madagascar’s rainforests

Published by: AfDB


About

This paper analyses deforestation leakages from natural rainforests to anthropized habitats following the creation of Protected Areas in Madagascar. A simple theoretical framework highlights that a conservation constraint does not necessarily create deforestation leakages on secondary forests. An original dataset is built combining fine scale vegetation cover images and spatialized census data over the period 2000 to 2012. Cover images allow us to distinguish a mosaic of landscapes. Multilevel panel regressions and matching techniques indicate a causal effect of Protected Areas on deforestation leakages. Though Protected Areas reduce deforestation in protected natural forests, forest clearing is mostly reported on other types of anthropized forests. Our results demonstrate the limitations of Porter-like mechanism in agricultural innovation. They also support the hypothesis of a conservation dilemma: protecting biodiversity may come at the expense of the welfare of locals who rely on local (provisioning) ecosystem services.

Sustainably manage forests, combat desertification, halt and reverse land degradation, halt biodiversity loss

Human life depends on the earth as much as the ocean for our sustenance and livelihood. Plant life provides 80 percent of our human diet, and we rely on agriculture as an important economic resource and means of development. Forests account for 30 percent of the Earth’s surface, providing vital habitats for millions of species and important sources for clean air and water; as well as being crucial for combating climate change.

Today we are seeing unprecedented land degradation, and the loss of arable land at 30 to 35 times the historical rate. Drought and desertification is also on the rise each year, amounting to the loss of 12 million hectares and affects poor communities globally. Of the 8,300 animal breeds known, 8 percent are extinct and 22 percent are at risk of extinction.

The Sustainable Development Goals (SDGs) aim to conserve and restore the use of terrestrial ecosystems such as forests, wetlands, drylands and mountains by 2020. Promoting the sustainable management of forests and halting deforestations is also vital to mitigating the impact of climate change. Urgent action must be taken to reduce the loss of natural habitats and biodiversity which are part of our common heritage.

Conserving forests and other ecosystems is one of 17 Global Goals that make up the 2030 Agenda for Sustainable Development. An integrated approach is crucial for progress across the multiple goals.

The concept of long term sustainability of development programmes is constantly evolving.

The SDG Fund definition involves:

  1. Inclusion and participation in programme initiatives within the vision of a Human Rights-based approach
  2. Economic use of resources in programme implementation
  3. Sustainability of programme achievements after termination of activities
  4. Mainstreaming environment and climate change in development programmes

For our programmes integrating sustainability requires an analysis of the governance architecture and the different stages of the programme cycle. At the national level, this could include the formulation of national policies, long term and multi-year development plans, sectoral budgetary allocation processes, and regulatory processes. At the level of projects on the ground, climate change adaptation considerations might need to be factored within specific elements of the project cycle.

As an example, a key element to mainstreaming climate change is the use of a climate lens. The following criteria are essential elements to be observed:

  • The extent to which the policy, plan, or project under consideration could be vulnerable to risks arising from climate variability and change
  • The extent to which climate change risks have already been taken into consideration
  • The extent to which the policy, plan, or project could inadvertently lead to increased vulnerability and maladaptation or miss important opportunities arising from climate change

The following publications offer useful guidance for introducing environmental sustainability and climate change sensitivity into development programmes:
