Slower than desired growth in crop yields coupled with rising food demand present ongoing challenges for food security in Africa. Some countries, such as Tanzania, have signed the Malabo and Abuja Declarations, which aim to boost food security through increasing crop productivity. The more intensive use of seed and fertilizer presents one approach to raising crop productivity. Our simulation study examined the productivity and economic effects of planting different seed cultivars and increasing fertilizer application rates at multiple spatial scales for maize in Tanzania.

The construction of consistent time series of land use presents a key challenge when accounting for elective land use-based activities under the Kyoto Protocol (wetland drainage and rewetting (WDR), cropland management (CM) and grazing land management (GM)), in which current land use-driven greenhouse gas emissions are compared to a reference situation in 1990. This case study is the first to demonstrate the feasibility of using high-resolution land-use proxies from different datasets for Kyoto accounting in a data-rich case study region in Germany.

The contribution of small farms to local food supply, food security and food sovereignty is widely acknowledged at a global level. In the particular case of Europe, they often are seen as an alternative to large and specialised farms. Assessing the real role of small farms has been limited by a lack of information, as small farms are frequently omitted from agricultural censuses and national statistics.

Oil palm plantations in Indonesia have been linked to substantial deforestation in the 1990s and 2000s, though recent studies suggest that new plantations are increasingly developed on non-forest land. Without nationwide data to establish recent baseline trends, the impact of commitments to eliminate deforestation from palm oil supply chains could therefore be overestimated. We examine the area and proportion of plantations replacing forests across Sumatra, Kalimantan, and Papua up to 2015, and map biophysically suitable areas for future deforestation-free expansion.

The values ascribed to industrial tree plantations are often controversial. Hence knowledge of their perceived impacts is important for improving their integration in rural landscapes. In 2016 we conducted household surveys with 606 respondents living in villages adjacent to acacia, teak and pine plantations across three islands in Indonesia (Java, Borneo, Sumatra). Results show that perceptions toward pine and teak plantations tend to differ from those toward acacia pulpwood plantations in several ways.

Understanding stakeholder power relations—such as between land sellers, land buyers, and local governments—is crucial to understanding Land Value Capture (LVC). While scholars have focused on stakeholder relationships through approaches such as stakeholder salience, stakeholder interaction, stakeholder value network, and stakeholder multiplicity, much research either places insufficient focus on power or only stresses partial attributes of power. As a result, the role of power relations among key stakeholders in LVC remains insufficiently explored.

The transition of farms and ranches to the next generation has generated considerable attention and concern. Over the past 30 years, public and private institutions across the U.S. have introduced policies and programs to help farms without identified family successors achieve successful transfers by connecting them with new farmers through “farm link” services. However, the effectiveness of these services is unclear and assessment is needed.

Colombia’s Andean-Amazonian foothills are among the most pressing deforestation hotspots in the country. Yet, the relationships and dependencies of underlying deforestation drivers are not well understood. For an adequate territorial reorganization in the post-conflict era that is sensitive to local context, a targeted analysis of the present situation at the local level is required. This study investigates direct and indirect deforestation drivers, relationships among these and potential measures to lower deforestation post-conflict.

Since around 2011 pilot projects to innovate land tenure documentation are being implemented in various countries in the global south in order to address the shortcomings of formal land registration. A longer-term question, underlying the present study, is how these innovations relate in the longer run to existing institutional arrangements of land governance in the respective context of implementation. Guided by this more general question, we discuss in this paper first the characteristics for 6 of these approaches.

Between 1940 and 2000, nearly 10 million housing units were constructed throughout California. This increased interaction between human and natural communities creates a number of significant socio-ecological challenges. Here we present a novel spatially explicit model that allows better characterization of the extent and intensity of future housing settlements using three development scenarios between 2000 and 2050. We estimate that California's exurban land classes will replace nearly 12 million acres of wild and agricultural lands.

While strengthening women’s land rights is increasingly on national and international agendas, there is little consensus on how to understand women’s tenure security. Analyses of women’s land rights often use very different definitions of land rights, from formal ownership to women’s management of plots allocated to them by their husbands. This paper identifies aspects of women’s tenure that should be included in indicators. It then provides a conceptual framework to identify the various dimensions of women’s land tenure security and the myriad factors that may influence it.

The viability of the climate pledges made by Brazil at the COP21 in Paris, 2015, heavily depends on the success of the country policies related to forest governance. Particularly, there are high expectations that the enforcement of the Brazilian Forest Code (BFC) will drive large-scale forest recovery and carbon mitigation. In this study, we quantified the potential role that ongoing forest regeneration may play in offsetting deficits from private properties with less vegetation cover than determined by the BFC, considering different law implementation settings.
