Abstract

As a consequence of recent human activities. populations of approximately 75% of the world’s primates are in decline, and more than 60% of species (n = 512) are threatened with extinction. Major anthropogenic pressures on primate persistence include the widespread loss and degradation of natural habitats caused by the expansion of industrial agriculture, pastureland for cattle, logging, mining, and fossil fuel extraction. This is the result of growing global market demands for agricultural and nonagricultural commodities. Here, we profile the effects of international trade of forest-risk agricultural and nonagricultural commodities, namely soybean, oil palm, natural rubber, beef, forestry products, fossil fuels, metals, minerals, and gemstones on habitat conversion in the Neotropics, Africa, and South and Southeast Asia. Total estimated forest loss for these regions between 2001 and 2017 was ca 179 million ha. The average percent of commodity-driven permanent deforestation for the period 2001–2015 was highest in Southeast Asia (47%) followed by the Neotropics (26%), South Asia (26%), and Africa (7%). Commodities exports increased significantly between 2000 and 2016 in all primate range regions leading to the widespread conversion of forested land to agricultural fields and an increase in natural resource extraction. In 2016, US $1.1 trillion of natural-resource commodities were traded by countries in primate range regions. The Neotropics accounted for 41% of the total value of these exports, Southeast Asia for 27%, Africa 21%, and South Asia 11%. Major commodity exporters in 2016 were Brazil, India, Indonesia, Malaysia and South Africa, countries of high primate diversity and endemism. Among the top 10 importers were China, the US, Japan, and Switzerland. Primate range countries lag far behind importer nations in food security and gross domestic product per capita, suggesting that trade and commodity-driven land-use have done little to generate wealth and well-being in primate habitat countries. Modeling of land-use and projected extinction of primate species by 2050 and 2100 under a business as usual scenario for 61 primate range countries indicate that each country is expected to see a significant increase in the number of species threatened with extinction. To mitigate this impending crisis, we advocate the “greening” of trade, a global shift toward a low-meat diet, reduced consumption of oil seed, diminished use of tropical timber, fossil fuels, metals, minerals, and gemstones from the tropics, accompanied by a stronger and sustained global resolve to regulate and reverse the negative impacts of growing unsustainable global demands and commodity trade on income inequality, and the destruction of primates and their habitats.

Highlights

  • International commodities trade has become the backbone of many of the world’s economies

  • The Neotropics was the region with most forest loss (83.5 million ha) followed by Southeast Asia with 54.3 million ha (Table 1)

  • This is consistent with a recent study based on remote sensing indicating that between 2001 and 2015, 27% of global forest loss (>30% canopy cover) worldwide was attributed to deforestation through permanent land use change for commodity production

Summary

Introduction

International commodities trade has become the backbone of many of the world’s economies. The volume of food and nonfood commodities traded globally has increased by over 60% since the turn of the century, with four trillion US dollars of natural resource commodities traded in 2016 (https://resourcetrade.earth/) The trade of these commodities has had a direct impact on land-use change and environmental and social policies in exporting countries (Henders, Persson & Kastner, 2015; Henders et al, 2018), and in many instances these policies, driven by the over-consumption of a few major importing countries, have resulted in large-scale deforestation, the poisoning of soil, streams, and rivers, and transformed biodiverse landscapes into monocultures (Gardner et al, 2018; MacDonald et al, 2015; Moran, Petersone & Verones, 2016). Commercial agriculture at local and global scales is the most significant driver of deforestation worldwide (Hosonuma et al, 2012)
