Agricultural land accounts for 37% of the world's terrestrial area, and the multiple functions of agroecosystems-providing food, soil and water retention, and various cultural services-are of great importance for sustainable land management. To ensure that multifunctionality, payment for ecosystem services (PES) schemes have been developed for heterogeneous agroecosystems. However, the effects of the schemes have not been fully measured because, in most cases, they have been implemented as action-oriented programs rather than outcome-based payments.

Article Synopsis
  • Extreme weather events like the typhoon Hagibis in October 2019 highlight the increasing frequency of natural disasters due to climate change, leading to significant evacuations and damage.
  • Effective early warning systems (EWS) are essential for minimizing the impacts of floods, but traditional hazard monitoring alone is not enough.
  • Integrating social media data, like tweets, with hazard monitoring can enhance EWS by improving early detection and local identification of flood events, allowing for better decision-making and preparedness.

Sustainable land use is a fundamental research field for land use planning. However, regional policymakers often lack access to the theoretical impacts that a land use policy might have on local development, especially in remote agricultural areas. Furthermore, knowledge exchange is important, especially in the context of globalization.

Cropland expansion to meet the growing demand for food and fuel is a driving factor in forest degradation. Over the next few decades, increases in the area of agricultural land are expected to be concentrated in sub-Saharan Africa, which still has large tracts of unexploited land suitable for agricultural production. We analyzed land-cover change in northern Ghana between 1984 and 2015 and compared it with background social factors associated with land change.
