Desertification, land degradation and drought

Using newly-released and globally available high-resolution remote sensing data on forest loss, the authors update the assessment of the cross-country determinants of deforestation in developing countries. Agricultural trade, relatively neglected to date, is found to be one of the main factors causing deforestation. Insights into the relationship between the levels of forestation and trade are vital for understanding how to address SDG 15.2 to promote the implementation of sustainable management of all types of forests.
This study has investigated how smallholder farmers contribute to our global food supply. They looked at where farms are located, what type of commodities are produced (plants, livestock’s or fish) from farms of different sizes and their nutrition implications. They found that small farms produce 75–100% of all cereal in North America and South America, Australia, and New Zealand , livestock, and fruit in these regions, whereas small farms (<20 ha) found in sub-Saharan Africa, South Asia, southeast Asia, and China produce 75% of food commodities globally. This is in line with the attainment of SDG 2.
Maize growing under plastic

Critics claim that maize can cause unwanted environmental impacts. But supporters of the crop are able to show how by use of cover crops it can be grown responsibly, reducing or eliminating, for example, nutrient leaching and soil erosion. In south-west England, a Wessex Water project is using cover crops to protect and improve drinking water quality by working with growers whose farms surround boreholes and reservoirs that supply water for human consumption. Steps like this can contribute to SDG 6 to ensure sustainable management of water and SDG 12 to ensure sustainable production.

Reducing large-scale deforestation in commodity frontiers remains a key challenge for climate change mitigation and the conservation of biodiversity. Public and private anti-deforestation policies have been shown to effectively reduce forest loss, but the conditions under which such policies get adopted are rarely examined. This paper proposes a set of conditions for the adoption of effective anti-deforestation policies. Such conditions will help to advance SDG 15.2 to promote the implementation of sustainable management of all types of forests and halt deforestation.

Contributing to SDG 15 (Life on Land), this Elsevier Atlas Award winning article quantifies changes in spatial and temporal patterns of human pressure and ecological state across the entire global network of Natural World Heritage Sites and their surrounding landscapes for the first time.
The Blueprint for Business Leadership on the SDGs aims to inspire all business — regardless of size, sector or geography — to take leading action in support of the achievement of the Sustainable Development Goals (SDGs). It illustrates how the five leadership qualities of Ambition, Collaboration, Accountability, Consistency, and Intentional can be applied to a business' strategy, business model, products, supply chain, partnerships, and operations to raise the bar and create impact at scale. The Blueprint is a tool for any business that is ready to advance its principled approach to SDG action to become a leader. This chapter relates specifically to SDG 15.
This paper uses ‘Medieval’ drought conditions from the 12th Century to simulate the implications of severe and persistent drought for the future of water resource management in metropolitan Phoenix, one of the largest and fastest growing urban areas in the southwestern USA. Anticipatory models enable long-term policy analysis for climate change. Mega-drought results in unsustainable groundwater use between 2000 and 2060. Aggressive drought management policies can produce sustainable yield. The time to manage droughts is before they occur. This relates to SDG 6, SDG 11 and SDG 13.
This report offers a framework for principle-based collaboration between business, the UN, governments, civil society and other stakeholders in relation to soil management and the entire agricultural value chain. It directly supports SDG 2 and SDG 15.
This report highlights the benefits for businesses of implementing adaptation activities that contribute to increasing societal resilience and attaining Goal 15.
Linking to Goals Goal 2, 6, 12, 15, 17, these guidelines respond to the integrity challenges facing water stewardship initiatives (WSIs).
