Tropical PeatLand Forest Biomass Estimation Using Polarimetric Parameters Extracted from RadarSAT-2 Images

Peer-reviewed publication

United States of America

This paper was aimed at estimating the forest aboveground biomass (AGB) in the Central Kalimantan tropical peatland forest, Indonesia, using polarimetric parameters extracted from RadarSAT-2 images. Six consecutive acquisitions of RadarSAT-2 full polarimetric data were acquired and polarimetric parameters were extracted. The backscattering coefficient ( σ o ) for HH, HV, VH, and VV channels was computed respectively. Entropy (H) and alpha ( α ) were computed using eign decomposition.

Sources of Land Information in South Africa and their Institutional Context

Reports & Research
Mayo, 2020
South Africa

Land Portal and the Council for Scientific and Industrial Research (CSIR) have collaborated on this project designed “…to uncover, democratize and improve the land data and information ecosystem in South Africa” (Land Portal Foundation, 2019). This is one of a number of State of Land Information (SoLI) projects in an international process covering a number of countries. The first part of the project involved in-country teams scoping the information landscape (resulting in this report).

Does social capital matter in climate change adaptation? A lesson from agricultural sector in Yogyakarta, Indonesia

Peer-reviewed publication
Mayo, 2020
Indonesia

Climate change increases the vulnerability of agricultural sector due to the increasing threat from pest attacks. Mitigation of a threat that results from climate change requires adaptation strategies. This study investigates farmers’ willingness to participate in the process of climate change adaptation in Yogyakarta, Indonesia; particularly in facing the increasing risk of pest attacks. Using a logistic regression model, we tested the impacts of social capital on farmers’ willingness to participate.

Legal aspects of synchronising data on real property location in polish cadastre and land and mortgage register

In recent years, many attempts have been made in Poland to enable automatic data exchange between the system of the Cadastre, being the responsibility of local government units, and the system of Land and Mortgage Register, maintained by the judicial administration (supported by the state apparatus represented by the Ministry of Justice). Such exchange is necessary as it is dictated by the establishment of the Integrated Real Estate Information System.

Adoption and diffusion of improved technologies and production practices in agriculture: Insights from a donor-led intervention in Nepal

Peer-reviewed publication
Mayo, 2020
Nepal

Adoptions of improved technologies and production practices are important drivers of agricultural development in low-income countries like Nepal. Adopting a broad class of such technologies and practices is often critical for meeting the multifaceted goals of efficiency, profitability, environmental sustainability, and climate resilience.

Transfer of development rights, farmland preservation, and economic growth: a case study of Chongqing’s land quotas trading program

Peer-reviewed publication

The dilemma between preserving farmland and urbanization has attracted many policymakers’ attention. One sound solution that has been practiced in several developed countries is the “transfer of development rights” (TDR). This study examines a specific TDR program in China—the Chongqing Land Quotas Trading program. We use a synthetic control method on the 2001–2014 statistics of 57 prefectures to quantitatively assess the program’s effect on farmland preservation and economic growth.

Farming systems and Conservation Agriculture: Technology, structures and agency in Malawi

Peer-reviewed publication
Mayo, 2020
África subsahariana

Conservation Agriculture (CA) is advocated as an agricultural innovation that will improve smallholder famer resilience to future climate change. Under the conditions presented by the El Niño event of 2015/16, the implementation of CA was examined in southern Malawi at household, district and national institutional levels. Agricultural system constraints experienced by farming households are identified, and in response the technologies, structures and agency associated with CA are evaluated.

Assessing the relationship between land tenure issues and land cover changes around the Arabuko Sokoke Forest in Kenya

Peer-reviewed publication
Mayo, 2020
Kenya
Noruega

Land as an essential resource is becoming increasingly scarce due to population growth. In the case of the Kenyan coast, population pressure causes land cover changes in the Arabuko Sokoke Forest, which is an important habitat for endangered species. Forest and bushland have been changed to agricultural land in order to provide livelihood for the rural population who are highly dependent on small-scale farming. Unclear land rights and misbalanced access to land cause uncontrolled expansion and insecure livelihoods.

How and why large scale agricultural land investments do not create long-term employment benefits: A critique of the ‘state’ of labour regulations in Ghana

Peer-reviewed publication
Mayo, 2020
República Centroafricana
Ghana

Support for large scale agricultural investments in Africa has been mainly premised on their employment prospects for local populations. However, despite earlier calls by Tania Li to centre labour in the land grabs debate, labour is generally invisible in both mainstream policy and academic research. This paper, through a governance lens, draws attention to the implications of the global land rush on wage labour.

The Montado/Dehesa Cow-Calf Production Systems in Portugal and Spain: An Economic and Resources’ Use Approach

Peer-reviewed publication

Spain
Portugal
United States of America

The Montado in Portugal and Dehesa in Spain is a unique agro-silvo-pastoral system designed to overcome food needs in a scarce resource’s environment. The system competitiveness is not clear and it is now under severe threats, caused by extensification or abandonment of less fertile areas and by intensification in more fertile ones.

On How Crowdsourced Data and Landscape Organisation Metrics Can Facilitate the Mapping of Cultural Ecosystem Services: An Estonian Case Study

Peer-reviewed publication
Mayo, 2020
Estonia

Social media continues to grow, permanently capturing our digital footprint in the form of texts, photographs, and videos, thereby reflecting our daily lives. Therefore, recent studies are increasingly recognising passively crowdsourced geotagged photographs retrieved from location-based social media as suitable data for quantitative mapping and assessment of cultural ecosystem service (CES) flow. In this study, we attempt to improve CES mapping from geotagged photographs by combining natural language processing, i.e., topic modelling and automated machine learning classification.

Mapping Suburbs Based on Spatial Interactions and Effect Analysis on Ecological Landscape Change: A Case Study of Jiangsu Province from 1998 to 2018, Eastern China

Peer-reviewed publication
Mayo, 2020
Global

As the transitional area between urban and rural areas, land-use change in suburbs is drastic, which generates negative effects on the ecological environment. However, the identification of the suburbs remains controversial. Usually, the density of the population and residential land is referenced, and the close spatial interactions between urban areas and suburbs are generally neglected. To fill this research gap, this study adopts a case study method to map the suburbs of Jiangsu based on estimating the spatial interactions.
