Crowdsourced Street-Level Imagery as a Potential Source of In-Situ Data for Crop Monitoring

Peer-reviewed publication
Dezembro, 2018
Países Baixos

New approaches to collect in-situ data are needed to complement the high spatial (10 m) and temporal (5 d) resolution of Copernicus Sentinel satellite observations. Making sense of Sentinel observations requires high quality and timely in-situ data for training and validation. Classical ground truth collection is expensive, lacks scale, fails to exploit opportunities for automation, and is prone to sampling error.

Re-Evaluating the Climate Factor in Agricultural Land Assessment in a Changing Climate—Saskatchewan, Canada

Peer-reviewed publication
Março, 2019
Canadá

We established the statistical relationships between seasonal weather variables and average annual wheat yield (Hard Red Spring and Durum wheat: Triticum spp.) for the period of 1979–2016 for 296 rural municipalities (RMs) throughout six soil zones comprising the arable agricultural zone of Saskatchewan, Canada. Controlling climate variables were identified through Pearson’s product moment correlation analysis and used in stepwise regression to predict wheat yields in each RM.

Improved Change Detection with Trajectory-Based Approach: Application to Quantify Cropland Expansion in South Dakota

Peer-reviewed publication
Abril, 2019
Global

The growing demand for biofuel production increased agricultural activities in South Dakota, leading to the conversion of grassland to cropland. Although a few land change studies have been conducted in this area, they lacked spatial details and were based on the traditional bi-temporal change detection that may return incorrect rates of conversion. This study aimed to provide a more complete view of land conversion in South Dakota using a trajectory-based analysis that considers the entire satellite-based land cover/land use time series to improve change detection.

A Review of Libyan Soil Databases for Use within an Ecosystem Services Framework

Peer-reviewed publication
Maio, 2019
Líbia

Ecosystem services (ESs) are increasingly being used by many countries around the world as a framework for addressing the United Nations (UN) Sustainable Development Goals (SDGs). This review article of the usability of Libyan soil databases for ESs and SDGs is the first of its kind for North Africa.

Experiences from a National Landscape Monitoring Programme—Maintaining Continuity Whilst Meeting Changing Demands and Opportunities

Peer-reviewed publication
Maio, 2019
Global

Over the past few decades, there has been increasing interest in recording landscape change. Monitoring programmes have been established to measure the scope, direction and rate of change, and assess the consequences of changes for multiple interests, such as biodiversity, cultural heritage and recreation. The results can provide feedback for multiple sectors and policy domains. Political interests may change over time, but long-term monitoring demands long-term funding. This requires that monitoring programmes remain relevant and cost-efficient.

The Spatial-Temporal Dynamics of Potato Agrobiodiversity in the Highlands of Central Peru: A Case Study of Smallholder Management across Farming Landscapes

Peer-reviewed publication
Novembro, 2019
Peru

In the high Andes, environmental and socio-economic drivers are transforming agriculture and presumably affecting the in situ conservation of potato (Solanum spp.). To monitor the use and conservation of intraspecific diversity, systematic and comparative studies across agricultural land-use systems are needed. We investigated the spatial-temporal dynamics of potato in two landscapes of Peru’s central Andes: A highland plateau (Huancavelica) compared to an eastern slope (Pasco).

Gender Opportunities and Constraints in Land-Related Agricultural Investments

Laos

WEBSITE INTRODUCTION: This report presents a synthesis of the main findings from case studies carried out in six countries in Africa (Ghana, Sierra Leone, United Republic of Tanzania and Zambia) and Asia (Laos and Philippines). The findings were disseminated and discussed in multistakeholder initiatives at regional and country level. The report illustrates how poor rural women and men are affected differently by agricultural investments, and demonstrates that they may not benefit equally from emerging opportunities.

How does organic agriculture contribute to food security of small land holders?: A case study in the North of Thailand

Journal Articles & Books
Dezembro, 2018
Tailândia

There has been a trend to encourage organic agriculture in response to improve global food security. This article investigated how organic agriculture contributed to food security of small land holders experiencing organic agriculture. It involved in-depth interview, focus group, and participatory observation from a purposive sample of thirty participants at San Sai and Muang Wa Villages, Luang Neua Sub-District, Doi Sa Ket District, Chiang Mai Province, the north of Thailand.

Circular labor migration and land-livelihood dynamics in Southeast Asia's concession landscapes

Vietnam

Labor migration and large-scale land enclosures are increasingly central to the story of agrarian change throughout the Global South. Nonetheless, there remain limited understandings of how recent explosions of mobile labor and new sources of smallholder capital shape and are shaped by ongoing land use and property transformations. This article reviews this gap in Southeast Asia – a region where labor and capital are highly mobile and where the expansion of industrial agriculture and forestry has been particularly rapid.

Large-Scale Land Acquisitions for Agricultural Development in Myanmar: A Review of Past and Current Processes

Reports & Research
Dezembro, 2018
Myanmar

WEB INTRODUCTION: The literature on agricultural large-scale land acquisition in Myanmar is rather fragmented and consists mainly of case studies. While these provide key insights into particular stories, they often fail to identify the main patterns and trends at country level. To fill such gaps, this thematic study aims to present an updated synthesis of the genealogy, institutional complexity and the ins and outs of large-scale land acquisition processes for agricultural development in Myanmar.

Land consolidation as technical change: Economic impacts in rural Vietnam

Journal Articles & Books
Fevereiro, 2020
Vietnam

This paper deepens the economic analysis of the effects of land consolidation – reduction of land fragmentation. It does this in the context of rural Vietnam, studying whether land consolidation promotes or hinders the Vietnamese government's policy objectives of encouraging agricultural mechanization and stimulating the off-farm rural economy. The analysis views land consolidation as a form of technical change, making it possible to apply the rich insights developed in the economic literature on that subject.

Linking climate change strategies and land conflicts in Cambodia: Evidence from the Greater Aural region

Journal Articles & Books
Dezembro, 2018
Cambodja

This paper investigates how climate change strategies and resource conflicts are shaping each other in the Greater Aural region of western Cambodia. Agro-industrial projects linked to climate change goals are reshaping both social and ecological dynamics, by altering patterns of access to land and water resources as well as the nature of the resources themselves. Using a landscape perspective, we investigate these social and ecological changes occurring across space and time.
