Disentangling the numbers behind agriculture-driven tropical deforestation

Science, Journal Year: 2022, Volume and Issue: 377(6611)

Published: Sept. 8, 2022

Tropical deforestation continues at alarming rates with profound impacts on ecosystems, climate, and livelihoods, prompting renewed commitments to halt its continuation. Although it is well established that agriculture a dominant driver of deforestation, mechanisms remain disputed often lack clear evidence base. We synthesize the best available pantropical provide clarity how drives deforestation. most (90 99%) across tropics 2011 2015 was driven by agriculture, only 45 65% deforested land became productive within few years. Therefore, ending likely requires combining measures create deforestation-free supply chains landscape governance interventions. highlight key remaining gaps including trends, commodity-specific land-use dynamics, data from tropical dry forests Africa.

Mechanical weeding enhances ecosystem multifunctionality and profit in industrial oil palm

Nature Sustainability, Journal Year: 2023, Volume and Issue: 6(6), P. 683 - 695

Published: March 2, 2023

Abstract Oil palm is the most productive oil crop, but its high productivity associated with conventional management (that is, fertilization rates and herbicide application), causing deleterious environmental impacts. Using a 2 factorial experiment, we assessed effects of vs reduced (equal to nutrients removed by fruit harvest) mechanical weeding on ecosystem functions, biodiversity profitability. Analysing across multiple exhibited higher multifunctionality than treatment, although this effect was concealed when evaluating only for individual functions. Biodiversity also enhanced, driven 33% more plant species under weeding. Compared management, increased profit 12% relative gross margin 11% due reductions in material costs, while attaining similar yields. Mechanical reduced, compensatory mature plantations tenable option enhancing increasing profit, providing win–win situations.

The Perils of Wishful Thinking: A Response to Peterson, Bedner, and Berenschot

Can legal remedies act as a line of defence against dispossession? Although the system in Indonesia very rarely yields outcomes that scholars and activists seem to prefer, "The Perils Legal Formalism," addressing widespread conflicts caused by expansion oil palm plantations, argues it can. Yet, political economy Indonesia's "extractive regime" has long relied on violent dispossession. A Poulantzian Marxist analysis law provides firmer ground for understanding ineffectiveness itself reforming society. Peterson, Bedner, Berenschot's (2025) puzzlement at formalistic decisions Indonesian judges incompetence plaintiff lawyers representing displaced communities reveals their individualist, law-centric approach reluctance abandon liberal myths rule autonomy from "the rest" Optimistic reformist efforts may offer veneer legitimacy while actually strengthening extractive regime power dominant actors who benefit it. Against such wishful thinking, rare case effective mobilisation West Sumatra illustrates how action can only be impactful if deployed combination with built over time collective actors.

Trends in tropical forest loss and the social value of emission reductions

Nature Sustainability, Journal Year: 2023, Volume and Issue: 6(11), P. 1373 - 1384

Published: July 13, 2023

Abstract Reducing global forest losses is essential to mitigate climate change and its associated social costs. Multiple market non-market factors can enhance or reduce loss. Here, understand the role of (for example, policies, anomalies conflicts), we compare observed trends a reference (expected) scenario that excludes factors. We define an expected by simulating land-use decisions solely driven prices, productivities presumably plausible decision-making. The allocation model considers economic profits uncertainties as incentives for conversion. in Brazil, Democratic Republic Congo Indonesia (2000–2019) with assign differences from Our results suggest temporarily lead lower-than-expected summing 11.1 million hectares, but also phases higher-than-expected 11.3 hectares. Phases occurred earlier than those losses. damages avoided delaying emissions would otherwise have represent value US$61.6 billion (as year 2000). This result shows importance conservation efforts tropics, even if reduced loss might be temporary reverse over time.

Deforestation and greenhouse gas emissions could arise when replacing palm oil with other vegetable oils

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 914, P. 169486 - 169486

Oil crops are among the main drivers of global land use changes. Palm oil is possibly most criticized, as a driver primary tropical forests loss. This has generated two different reactions in its various sectors (e.g., food, feed, biodiesel, surfactant applications, etc.): from one side there growing claim for deforestation-free palm oil, whereas on other attention raised towards vegetable oils possible substitutes, such soybean, rapeseed and sunflower oil. We assess potential changes consequent greenhouse gas (GHG) emissions switching to compare this solution oils. consider three scenarios 25 %, 50 % 100 replacement eight major crop producing countries.

Insights from 20 years of mammal population research in Indonesia

Oryx, Journal Year: 2024, Volume and Issue: 58(4), P. 485 - 492

Published: March 22, 2024

Abstract Mammal populations are declining in biodiverse tropical regions. Global analyses have identified Indonesia as a hotspot of vertebrate decline, although relatively few data available to substantiate these claims. We reviewed research articles published during 2000–2020 on 104 medium-sized large terrestrial mammal species found help inform conservation management and future research. 308 peer-reviewed studies English or Bahasa Indonesia, with an increase publication rate (articles per year) over time. Studies distributions dominated the literature, followed by publications abundance, diversity combinations topics. Most concerned single-species conducted at single location point identify four key issues that should be addressed efforts: (1) disproportionate focus small number species; (2) geographical bias towards west (Sumatra, Kalimantan Java–Bali), from central (Sulawesi, Nusa Tenggara Maluku) east (Papua) Indonesia; (3) limitations survey design, sampling effort analysis; (4) lack long-term wildlife population studies. also note challenges local researchers face publishing their international journals because language barriers costs. Greater use existing biodiversity continued capacity building for researchers, particularly those critical effectively guide monitoring improve status Indonesian mammals.
