    The pressure on land is growing in many regions of the world, due to the increasing demand for arable crops, meat and dairy products, bio-energy and timber, and is exacerbated by land degradation and climate change. This policy report provides scenario projections for the UNCCD Global Land Outlook, exploring future changes to the use and condition of land and the resulting impacts on food, water, climate change and biodiversity.

    The Scientific Conceptual Framework for Land Degradation Neutrality (LDN) provides a scientific foundation for understanding, implementing and monitoring LDN. It has been designed to create a bridge between the vision and the practical implementation of LDN, by defining LDN in operational terms. The conceptual framework is a product of the UNCCD Science-Policy Interface. Pursuit of LDN requires effort to avoid further net loss of the land-based natural capital relative to a reference state, or baseline.

    Widespread palm oil production causes much controversy due to its negative impacts in the tropics. But whatever is said about it, it is big business and getting bigger by the day due to increasing global demands. Alongside this, the size and depth of the social and environmental debates surrounding palm oil production are also growing. As a major globally-consumed commodity, its production in the humid and sub-humid tropics raises concerns due to its impacts on the environment, biodiversity, local communities, smallholder livelihoods, land rights and climate change.

    Context: The provision of multiple ecosystem services (ES) within a landscape is commonly referred to as landscape multifunctionality. Modifying landscapes to increase multifunctionality and reduce trade-offs with concurrent services bears the potential to enhance sustainability in human-dominated landscapes. Assessing landscape multifunctionality is thus crucial for land management and planning, but lack of a clear definition and operationalization of multifunctionality impedes comparisons of different study results.

    Context: Hedgerows are typical landscape features of high environmental and cultural value that often have been sacrificed for agricultural intensification and scale enlargement. Objectives: We studied the dynamics of hedgerow quality over time in a case study area renowned for its hedgerow landscapes: South West Devon (UK) answering the following research questions: (1) how does the imperative of scale enlargement affect hedgerow quality? and (2) to what extent can cultural landscape degradation be countered by targeted policies?

    Riverine nitrogen (N) export is a crucial process that links upstream and downstream ecosystems and coastal zones. However, the driving forces of riverine N export that is closely related to water N pollution are still not well understood. In this study, we used a mass balance approach to quantify the sources of N discharge and analyzed the effect of land use composition on riverine N export, taking Zhejiang Province, China as a case study. We found that the total reactive N discharge to rivers in Zhejiang increased from 0.22 to 0.26 Tg yr-1 from 2000 to 2015.

    South Sudan

    Following South Sudanese independence in 2011, land reform became a major aspect of state building, partly to address historical injustices and partly to avoid future conflicts around land. In the process, land became a trigger for conflicts, sometimes between communities with no histories of “ethnic conflict.” Drawing on cases in two rural areas in Yei River County in South Sudan, this paper shows that contradictions in the existing legal frameworks on land are mainly to blame for those conflicts.

    Problems in agriculture and land use are increasingly recognised as complex, uncertain, operating at multiple levels (field to global value chains) and involving social, economic, institutional, and technological change. This has implications for how projects navigate complexity to achieve impact. However, few studies have systematically evaluated how project actors engage with other actors to configure capabilities and resources across multiple levels in agricultural innovation systems (AIS), from the individual to the network, to mobilise and build systemic innovation capacity.

    Research gaps in understanding flood changes at the catchment scale caused by changes in forest management, agricultural practices, artificial drainage, and terracing are identified. Potential strategies in addressing these gaps are proposed, such as complex systems approaches to link processes across time scales, long-term experiments on physical-chemical-biological process interactions, and a focus on connectivity and patterns across spatial scales.

    The cultivation of legumes is low in Europe. Public policy incentives and/or regulations have a role to play in changing this. This chapter examines six such policies. The CAPRI (Common Agricultural Policy Regional Impact) model, a partial equilibrium model for the agricultural sector, is used to simulate the effects of these policies and compare them to what would happen if no policy action were taken. Five of these policy scenarios are aimed at grain legumes (pulses and soybean), and one at forage legumes (in particular, clover).
