Inferring Missing Climate Data for Agricultural Planning Using Bayesian Networks

Peer-reviewed publication

Climate data availability plays a key role in development processes of policies, services, and planning in the agricultural sector. However, data at the spatial or temporal resolution required is often lacking, or certain values are missing. In this work, we propose to use a Bayesian network approach to generate data for missing variables. As a case study, we use relative humidity, which is an important indicator of land suitability for coffee production.

Land Use Dynamics of Drove Roads: The Case of Tratturo Castel di Sangro-Lucera (Molise, Italy)

Peer-reviewed publication

Organized transhumant pastoralism has contributed to shaping the cultural landscape of many countries. It has affected areas designated for grazing, temporary and permanent shelters, and towns. Through the analysis of historical maps and recent information, in a temporal range from 1652 to 2014, this study focused on changes in land cover and conservation status of one of the main Italian transhumance paths, namely the Tratturo Castel di Sangro-Lucera. Although there are some areas where this drove road is still recognizable, it is mostly identifiable only through a few tangible signs.

Effect of Land Use Change on Soil Carbon Storage over the Last 40 Years in the Shi Yang River Basin, China

Peer-reviewed publication

Accounting for one quarter of China’s land area, the endorheic Shiyang River basin is a vast semi-arid to arid region in China’s northwest. Exploring the impact of changes in land use on this arid area’s carbon budget under global warming is a key component to global climate change research. Variation in the region’s soil carbon storage due to land use changes occurring between 1973 and 2012 was estimated. The results show that land use change has a significant impact on the soil carbon budget, with soil carbon storage having decreased by 3.89 Tg between 1973 and 2012.

Urban Land Cover Change in Ecologically Fragile Environments: The Case of the Galapagos Islands

Peer-reviewed publication

The Galapagos Islands are a unique sanctuary for wildlife and have gone through a fluctuating process of urbanization in the three main inhabited islands. Despite being colonized since the 1800s, it is during the last 25 years that a dramatic increase in population has been observed. Analyzing impervious surface change over this period in an ecologically fragile environment is a challenging task, thus two methods that have been widely employed in studying urban environments were compared in this study: sub-pixel using spectral mixture analyses (SMA) and object-based classification.

Chiefs in a Democracy: A Case Study of the ‘New’ Systems of Regulating Firewood Harvesting in Post-Apartheid South Africa

Peer-reviewed publication
South Africa
Southern Africa

Much of the international commons literature reveals a decreased functioning of local traditional institutions that regulate natural resource harvesting. In South Africa, it is believed that the creation of new democratic structures at the end of Apartheid has contributed significantly to the deterioration in traditional resource regulation and this in turn has led to the extensive resource degradation seen in parts of the country. Many of these assertions, though, remain anecdotal in nature.

Investigation of Collapsed Building Incidents on Soft Marine Deposit: Both from Social and Technical Perspectives

Peer-reviewed publication
China

A collapsed incident occurred on 10 October 2016 in Wenzhou City, China, which resulted in 22 casualties and 6 injuries. Most of victims were migrant laborers (rural dwellers who move to urban for a temporary work), who rented apartments in these residential buildings, which were originally constructed by local rural residents. This case report investigates the collapsed incident as well as other similar previous incidents. From the perspectives of both social and technical aspects, this report analyzed the Chinese rural land use policy with relevant technical factors.

Post-War Land Cover Changes and Fragmentation in Halgurd Sakran National Park (HSNP), Kurdistan Region of Iraq

Peer-reviewed publication

Context: The fundamental driving force of land use and land cover (LULC) change is related to spatial and temporal processes caused by human activities such as agricultural expansion and demographic change. Landscape metrics were used to analyze post-war changes in a rural mountain landscape, the protected area of Halgurd-Sakran National Park (HSNP) in north-east Iraq. Therefore, the present work attempts to identify the temporal trends of the most fragmented land cover types between two parts of the national park.

A Land Systems Science Framework for Bridging Land System Architecture and Landscape Ecology: A Case Study from the Southern High Plains

Peer-reviewed publication

Resource-use decisions affect the ecological and human components of the coupled human and natural system (CHANS), but a critique of some frameworks is that they do not address the complexity and tradeoffs within and between the two systems. Land system architecture (LA) was suggested to account for these tradeoffs at multiple levels/scales. LA and landscape ecology (LE) focus on landscape structure (i.e., composition and configuration of land-use and land-cover change [LULCC]) and the processes (social-ecological) resulting from and shaping LULCC.

System Properties Determine Food Security and Biodiversity Outcomes at Landscape Scale: A Case Study from West Flores, Indonesia

Peer-reviewed publication

The food-biodiversity nexus is a concept that defines and characterizes the complex interactions between agricultural systems and biodiversity conservation. Here we use a social-ecological systems approach that combines fuzzy cognitive mapping and graph theoretic analyses to uncover system properties that determine food security and biodiversity outcomes at a landscape scale. We studied a rice-based agricultural landscape system situated in Mbeliling district of West Flores, Indonesia.

Estimation of the Spatiotemporal Patterns of Vegetation and Associated Ecosystem Services in a Bornean Montane Zone Using Three Shifting-Cultivation Scenarios

Peer-reviewed publication

Tropical countries are now facing increasing global pressure to conserve tropical forests, while having to maintain cultivated lands (particularly shifting cultivation) for the subsistence of local people. To accomplish the effective conservation of tropical forests in harmony with subsistence shifting cultivation, we evaluated the influence of shifting cultivation on ecosystem services (i.e., biodiversity and carbon stock) at a landscape level based on three land-use scenarios.

One Woman, One Hectare of Land CGE Report; Rural Development & Land Reform Budget Review & Recommendations Report

Legislation & Policies
October, 2015
South Africa

The Commission for Gender Equality presented on its proposed campaign called One Woman, One Hectare of Land’. The campaign aims to mainstream gender equality, for it was proposed that the State should allocate one hectare of land, for the growing of food, to the poorest rural female-run households. It was believed that this would help alleviate poverty and empower rural women. It was pointed out that where women had land, their families generally were better nourished, better educated and able to move on.
