The climate-smart agriculture (CSA) concept reflects an ambition
to improve the integration of agriculture development and climate
responsiveness. It aims to achieve food security and broader
development goals under a changing climate and increasing food
demand. CSA initiatives sustainably increase productivity, enhance
resilience, and reduce/remove greenhouse gases (GHGs), and
require planning to address trade-offs and synergies between
these three pillars: productivity, adaptation, and mitigation [1].

This study aims to explain effects of soil textural class, topography, land use, and land use history on soil greenhouse gas (GHG) fluxes in the Lake Victoria region. We measured GHG fluxes from intact soil cores collected in Rakai, Uganda, an area characterized by low‐input smallholder (<2 ha) farming systems, typical for the East African highlands. The soil cores were air dried and rewetted to water holding capacities (WHCs) of 30, 55, and 80%. Soil CO2, CH4, and N2O fluxes were measured for 48 h following rewetting.

This paper undertakes a comparative analysis of rural-urban land conversion policies in China and Vietnam, and examines the ideology of the state in land policymaking under a market socialism environment. It argues that land policies in both countries include ambiguous boundaries, which allow the socialist state to legitimize its politico-administrative power in land management and retain strong intervention capacity in the land market.

Urban agriculture is said to be increasing with global urbanization. However, there is little examination of the temporal or spatial dynamics of urban agriculture. We investigated the benefits and challenges experienced by community gardeners in four towns in South Africa, along with GIS analysis of the number, area, and location of urban food community gardens over the last three decades. Common reasons for practicing community gardening were cash poverty (37%) and the need to grow food (34%).

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.

Pantanal is one of the largest wetlands in the world. In its southern portion, it hosts significant beef cattle ranching, having a herd of 4,832,200 head of cattle in 2016 (IBGE, 2018). Yet it presents intra-regional differences and complementarities. This article discusses such current territory definition, focusing on cattle ranching in Pantanal, considering its forms of occupation, agents, and its intra-regional flow of cattle.

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.

Agricultural large-scale land acquisition (LSLA) is a process that is currently not captured by land change models. We present a novel land change modeling approach that includes processes governing LSLAs and simulates their interactions with other land systems. LSLAs differ from other land change processes in two ways: (1) their changes affect hundreds to thousands of contiguous hectares at a time, far surpassing other land change processes, e.g., smallholder agriculture, and (2) as policy makers value LSLA as desirable or undesirable, their agency significantly affects LSLA occurrence.

During the post-reform period since 1986, land-use systems in Vietnam have been reformed in terms of the regulation of land markets and the built environment. This study analyzes the changing role of urban planning and the policy of state intervention in land markets to manage spatial changes in Vietnamese cities. Theoretical and empirical approaches are used to analyze urban development and planning practices in Hanoi. The study further describes the constraints of planning systems in hybrid land markets that include both formal and informal land development.

The paper investigates the important role of fertilizer to enhance sustainable intensification and food security in Sub-Saharan Africa based on a multi-disciplinary literature review. The review starts with a macro-perspective taking population growth, economic development and climate change into account. This is complemented with a micro-perspective summarizing findings from comprehensive micro-data in selected African countries. Agronomic, environmental and economic profitability implications of fertilizer use are reviewed.

Global food security and agricultural land management represent two urgent and intimately related challenges that humans must face. The authors quantify the changes in the global agricultural land footprint if the world were to adhere to the dietary guidelines put forth by the United States Department of Agriculture (USDA), while accounting for the land use change incurred by import/export required to meet those guidelines. The authors analyze data at country, continental, and global levels.

Suboptimal land management practices are degrading soils and undermining food production. Sustainable land management (SLM) practices can improve soil and enhance yields.
