Property-level direct and indirect deforestation for soybean production in the Amazon region of Mato Grosso, Brazil

Peer-reviewed publication
Octobre, 2018
Brésil
États-Unis d'Amérique

Brazil’s Soy Moratorium solidified the world’s largest traders’ commitment to stop soybean purchases from production areas deforested after July 2006. The aim was to remove deforestation from the soybean supply-chain and halt one of the main drivers of forest loss in the Amazon biome. In this study, we investigated changes in deforestation at the property-level for the period 2004 to 2014.

Analyses of Land Cover Change Trajectories Leading to Tropical Forest Loss: Illustrated for the West Kutai and Mahakam Ulu Districts, East Kalimantan, Indonesia

Indonesia

In Indonesia, land cover change for agriculture and mining is threatening tropical forests, biodiversity and ecosystem services. However, land cover change is highly dynamic and complex and varies over time and space. In this study, we combined Landsat-based land cover (change) mapping, pixel-to-pixel cross tabulations and expert knowledge to analyze land cover change and forest loss in the West Kutai and Mahakam Ulu districts in East Kalimantan from 1990-2009.

Compliance with Planning Regulations in Hazardous Areas and its impacts. A Case of Msasani Bonde la Mpunga in Dar es Salaam City, Tanzania

Peer-reviewed publication
Août, 2018
Tanzania

 Most of the cities and urban centres of developing nations, Tanzania inclusive are faced with increased urbanization coupled with informal land development in non-designated areas including marginal and hazardous lands. This paper reports the findings of a study undertaken to assess the processes of land development and the associated impacts in Msasani Bonde la Mpunga, a, flood prone area in the City of Dar es Salaam.

Representing large-scale land acquisitions in land use change scenarios for the Lao PDR

Laos

Agricultural large-scale land acquisition (LSLA) is a process that is currently not captured by land change models. We present a novel land change modeling approach that includes processes governing LSLAs and simulates their interactions with other land systems. LSLAs differ from other land change processes in two ways: (1) their changes affect hundreds to thousands of contiguous hectares at a time, far surpassing other land change processes, e.g., smallholder agriculture, and (2) as policymakers value LSLA as desirable or undesirable, their agency significantly affects LSLA occurrence.

Vulnerability and Adaptation to Climate Change in Semi-Arid Areas in India

Reports & Research
Juillet, 2018
India
Southern Asia

This detailed report summarises key findings from an extensive Regional Diagnostic Study (RDS) for South Asia. Despite intense analytical efforts at the sub-regional level, reliable downscaled data may not be available with current models. As well, the spatial scale of available downscaled climate products (Regional Climate Models) may preclude their use in local decision-making. Often, locally significant drivers such as land use-land cover change overwhelm the influence of climatic drivers.

Exploring the socioeconomic and ecological consequences of cash crop cultivation for policy implications

Cash crops have kept expanding at an accelerating rate across the globe during the last decades. It therefore requires elaborate efforts to examine the socioeconomic and ecological consequences of cash crop cultivation. With a case of the Hangzhou region in subtropical China, this paper investigated the dynamic patterns of four cash crop types (tea, fruit, mulberry and nursery) at town level by using aerial photos; and then quantified the subsequent socioeconomic and ecological consequences using spatial regression.

Direct and indirect loss of natural habitat due to built-up area expansion: A model-based analysis for the city of Wuhan, China

Journal Articles & Books
Mai, 2018

Urbanization has been responsible for the loss of cropland worldwide, especially in China. To guarantee national food security, China has implemented a series of policies to protect cropland. One of these policies requires that one-hectare cropland should be reclaimed when urban expansion occupies one-hectare cropland. Since most cropland reclamation leads to a conversion of natural habitat, such as wetland and grassland, urban expansion may lead to (indirect) natural habitat loss in addition to direct loss from conversion of into urban area.

GlobeLand30 shows little cropland area loss but greater fragmentation in China

Journal Articles & Books
Avril, 2018

Understanding of cropland dynamics in a large geographical extent is mostly based on observations of area change, while the changes in landscape pattern are hardly assessed. The total amount of cropland in China has remained relatively stable in recent years, which might suggest there was little change. In this analysis, we combine the number of cropland patches (NP) with the total cropland area (TA) for a more comprehensive characterization of cropland change in China.

Farmers’ participation in the development of land use policies for the Central Rift Valley of Ethiopia

Journal Articles & Books
Février, 2018

Farmers in Ethiopia are elementary for the implementation of land use policies. However, in order to effectively implement these policies, they need to be aware of them, and accept them accordingly. In this study we assess to what extent farmers in the Central Rift Valley are aware of prevailing land use policies in their area, to what extent they participated in the development of these policies, and how they perceive the impacts of these policies, using interviews with local farmers as well as stakeholders from governmental institutions at various levels.

Effects of changes in land use and climate on water availability of a tropical catchment

Reports & Research
Février, 2018
Indonesia

Land use changes such as deforestation and urbanization influence the hydrology of catchments and hence water availability. Together with climate change, land use changes can affect the frequency of floods or droughts and thus threaten local or regional socio-economic development. For Indonesia, the effects of changes in land use and climate have been projected to cause a food crisis and eventually increase the degree of poverty in the future.

Haiti’s peasantry as poto mitan : refocusing the foundations of prosperity and development

Décembre, 2017
Haiti

The paper provides a case study of the conversion of state land in the Commune of Limonade, from a community-controlled agricultural economy to a large-scale agro-export banana plantation called Agritrans. This study shows how repurposing state land may impact food security and social stability of peasant farmers. The Agritrans plantation, designed and implemented by Haitian businessman and current President Jovenel Moïse, is used as a blueprint for Haiti’s development future.
