Linking Climate Change Adaptation and Mitigation: A Review with Evidence from the Land-Use Sectors

Peer-reviewed publication
Diciembre, 2018
Global

There is extensive scientific evidence that both adaptation and mitigation are essential to address the problem of climate change. However, there is still limited knowledge about the possibilities for exploiting the interrelationships between these measures in the design and implementation of climate change activities. In this paper, first the adaptation–mitigation dichotomy and definitions of adaptation and mitigation are discussed.

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

Peer-reviewed publication
Diciembre, 2018
Países Bajos

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.

Assessing the Value of Soil Inorganic Carbon for Ecosystem Services in the Contiguous United States Based on Liming Replacement Costs

Peer-reviewed publication
Diciembre, 2018
Estados Unidos de América

Soil databases are very important for assessing ecosystem services at different administrative levels (e.g., state, region etc.). Soil databases provide information about numerous soil properties, including soil inorganic carbon (SIC), which is a naturally occurring liming material that regulates soil pH and performs other key functions related to all four recognized ecosystem services (e.g., provisioning, regulating, cultural and supporting services). However, the ecosystem services value, or “true value,” of SIC is not recognized in the current land market.

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

Peer-reviewed publication
Marzo, 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.

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

Peer-reviewed publication
Mayo, 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.

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

Peer-reviewed publication
Mayo, 2019
Libia

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.

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
Noviembre, 2019
Perú

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).

Perspectivas de la agricultura y del desarrollo rural en las Américas: una mirada hacia América Latina y el Caribe

Policy Papers & Briefs
Octubre, 2019
América Latina y el Caribe

La Agenda 2030 para el Desarrollo Sostenible (Agenda 2030) es global en términos de su alcance y de los compromisos asumidos, que se organizan alrededor de sus 17 Objetivos de Desarrollo Sostenible (ODS) estrechamente interconectados entre sí, que la hacen indivisible por naturaleza.  “No dejar a nadie atrás” es uno de los principios fundamentales de la Agenda 2030, ya que su cumplimiento exige la participación de todos los sectores y actores de la sociedad, mediante alianzas para movilizar y compartir conocim

La ventaja de América Latina y el Caribe - La agricultura familiar: un factor decisivo para lograr la resiliencia de la seguridad alimentaria y la nutrición

Peer-reviewed publication
Septiembre, 2019
América Latina y el Caribe

Según un nuevo informe presentado hoy por el Fondo Internacional de Desarrollo Agrícola (FIDA), los proyectos de desarrollo que integran las inversiones en los pueblos indígenas rurales, los jóvenes y las mujeres con medidas para adaptarse al cambio climático tienen más probabilidades de tener éxito en América Latina y el Caribe.

La Agricultura Familiar Campesina

Journal Articles & Books
Noviembre, 2019
Bolivia

La agricultura familiar campesina (AFC) ha sido marginada sistemáticamente a pesar de su aporte a una alimentación sana y cuidado del medioambiente. Es tiempo de revalorizarla y abrir discusión desde una postura optimista, basada en observaciones directas en terrenos y marcos teóricos desarrollados por los agraristas de la corriente chayanoviana.

Land grabs and labour: Vietnamese workers on rubber plantations in southern Laos

Journal Articles & Books
Diciembre, 2019
Laos
Viet Nam

Since the early 2000s the Lao government has dramatically increased the number of large-scale land concessions issued for agribusinesses. While studies have documented the social and environmental impacts of land dispossession, the role of Vietnamese labour on these Vietnamese-owned rubber plantations has not previously been investigated. Taking a political ecology approach, we situate this study at the intersection between ‘land grabbing’ studies and work on ‘labour geographies’.
