Effects of Crop Rotation and Topography on Soil Erosion and Nutrient Loss under Natural Rainfall Conditions on the Chinese Loess Plateau

Peer-reviewed publication
December, 2022
Global

Erosive rainfall results in the loss of both soil and nutrients, which indirectly triggers soil deterioration and a reduction in land productivity. However, how rainfall affects runoff, soil erosion, and nutrient loss under different crop rotation patterns and topographic factors remains unclear. This experiment observed nine runoff-erosion plots on the Chinese Loess Plateau (CLP) from 2019 to 2020 to determine the effects of crop type, rotation pattern, and slope gradient and length on runoff, soil erosion, and nutrient loss.

Spatio-Temporal Analysis of Cultivated Land from 2010 to 2020 in Long’an County, Karst Region, China

Peer-reviewed publication
December, 2022
China

Spatio-temporal changes in cultivated land have a profound impact on food security and sustainable development. However, existing studies on spatio-temporal changes in cultivated land mostly focus on single factors, for instance quantity, quality and ecology, that cannot comprehensively reflect the changes in total production capacity and the sustainability of cultivated land.

Drivers of Degradation of Croplands and Abandoned Lands: A Case Study of Macubeni Communal Land in the Eastern Cape, South Africa

Peer-reviewed publication
December, 2022
South Africa

Soil erosion is a global environmental problem and a pervasive form of land degradation that threatens land productivity and food and water security. Some of the biggest sources of sediment in catchments are cultivated and abandoned lands. However, the abandonment of cultivated fields is not well-researched. Our study assesses the level of degradation in cultivated and abandoned lands using a case study in South Africa. We answer three main questions: (1) What is the extent of crop field degradation on used, partly used, and abandoned fields?

The Last Attempt at Land Reform in Spain: Application and Scope of the Andalusian Agrarian Reform, 1984–2011

Peer-reviewed publication
December, 2022
Spain

In this article, we contextualise, describe and analyse the last attempt at land reform in Spain—the one passed by the Autonomous Parliament of Andalusia in 1984. The Andalusians had passed their Statute of Autonomy by referendum in 1981, incorporating the mandate to carry out an agrarian reform that would boost the rural economy, generate employment and balance the agricultural structure of this region in Southern Spain, peripheral to both national and European centres of power.

Alaska Native Allotments at Risk: Technological Strategies for Monitoring Erosion and Informing Solutions in Southwest Alaska

Peer-reviewed publication
December, 2022
United States of America

After the United States’ purchase of Alaska from Russia in 1867, Alaska Native lands have existed in a legal state of aboriginal title, whereby the land rights of its traditional occupants could be extinguished by Congress at any time. With the passage of the Alaska Native Claims Settlement Act (ANCSA) in 1971, however, Alaska Native individuals were given the opportunity to select and secure a title to ancestral lands as federally administered ANCSA 14(c) allotments. Today, though, these allotments are threatened by climate-change-driven erosion.

Is Obliterated Land Still Land? Tenure Security and Climate Change in Indonesia

Peer-reviewed publication
December, 2022
Indonesia

Both human activities and climate change have changed landscapes significantly, especially in coastal areas. Sea level rise and land subsidence foster tidal floods and permanent inundations, thus changing and limiting land use. Though many countries, including Indonesia, are aware of these phenomena, the legal status of this permanently inundated land remains unclear. Indonesia refers to this land legally as obliterated land. This qualification makes former landowners uncertain, as it does not recognize their previous land rights, and creates disputes during land acquisition.

Testing and Enhancing the 8R Framework of Responsible Land Management with Documented Strategies and Effects of Land Reclamation Projects in Indonesia

Peer-reviewed publication
December, 2022
Indonesia

Whereas most contemporary frameworks evaluating land management aspects focus on institutional settings at a national level, the 8R framework of responsible land management aims at evaluating individual land management projects or interventions. This 8R framework is, however, still under development and needs testing, validation and further detailing, such that specific operational characteristics and internal and external effects can be included in the evaluation.

Mapping and Monitoring Spatio-Temporal Patterns of Rainfed Agriculture Lands of North Darfur State, Sudan, Using Earth Observation Data

Peer-reviewed publication
December, 2022
Global

Rainfed agriculture in Northern Darfur is influenced by erratic seasonal and decadal rainfall patterns and frequent droughts. Understanding the spatio-temporal variation in rainfed agriculture is crucial for promoting food security, socio-economic stability and protecting the vulnerable ecosystem. This study aimed to investigate the spatio-temporal dynamics of rainfed agriculture in North Darfur State from 1984–2019 using multitemporal Landsat observation data.

Community-Based Approaches in the Construction and Management of Water Infrastructures among the Chagga, Kilimanjaro, Tanzania

Peer-reviewed publication
December, 2022
Global

Water management among the Chagga people of Kilimanjaro has involved community collaboration in the construction, ownership and management of water infrastructures. Since the second half of the second millennium AD, the Chagga settlement on the lower slopes of Mt Kilimanjaro significantly transformed the landscape to reflect an agrarian society characterised by decentralised forms of socio-political and economic organisation.

The Governance of Land Use: A Conceptual Framework

Peer-reviewed publication
December, 2022
Global

How land is used is connected to some of the most important issues of our time: sustainable development, economic development, reducing territorial inequalities and the rights of future generations, to name but a few. There is growing recognition that a wide range of policies shape how land is used and managed beyond that of land use and environmental planning systems.
