    Inequality in land ownership remains a major issue in many developing countries, such as Brazil, Colombia, and South Africa. Donors advocate a new model of "willing-buyer/willing-seller\", market-led land redistribution, but actual redistribution has fallen short of expectations. Little effort has been made so far to formalize the obstacles to market-led land redistribution.

    The author describes a new type of negotiated land reform that relies on voluntary land transfers negotiated between buyers and sellers, with the government's role restricted to establishing the necessary framework for negotiation and making a land purchase grant available to eligible beneficiaries. This approach has emerged-following the end of the Cold War and broad macroeconomic adjustment--as many countries face a second generation of reforms to address deep-rooted structural problems and provide a basis for sustainable economic growth and poverty reduction.

    Agriculture influences and shapes the world’s ecosystems, but not always in a positive way. More than 2.5 billion people are globally involved as stewards of land and water ecosystems that constitute the natural resource base for feeding the current and future world population. Yet, conventional agronomic interventions based on ‘hard’ agricultural engineering compromise various eco-services that are required for sustainable agricultural development.

    Cattle grazing and fire are common types of management on natural ecosystems, generating several threats to the conservation of native vegetation (e.g., changes in species richness, cover, and abundance, mainly of bovine-palatable species). In this work, we analysed the response of the structure and composition of vegetation managed with different cattle stocking rates and fire in the savanna ecosystems of Colombia. The study was located in the eastern area of the Llanos region, where savannas were subjected to grazing and burning.

    Today, the design and remodeling of urban environments is being sought in order to achieve green, healthy, and sustainable cities. The effect of air pollution in cities due to vehicle combustion gases is an important part of the problem. Due to the indirect effect caused by the Covid-19 pandemic, political powers in Europe have imposed confinement measures for citizens by imposing movement restrictions in large cities. This indirect measure has given us a laboratory to show how the reduction in vehicle circulation affects in a short time the levels of air pollution in cities.

    There is little information concerning how people in the Global South perceive the benefits and costs associated with urban green areas. There is even less information on how governance influences the way people value these highly complex socio-ecological systems. We used semi-structured surveys, statistical analyses, and econometrics to explore the perceptions of users regarding governance and the benefits and costs, or Ecosystem Services (ES) and Ecosystem Disservices (ED), provided by Neotropical green areas and their willingness to invest, or not, for their conservation.

    In line with the Urban Agenda for the EU, this article highlights the importance of local actions in the conservation of biodiversity, both through specific activities and by increasing the availability of information. As such, the policies and projects related to the conservation of biodiversity have been analyzed here at different levels and, in particular, the initiatives undertaken in the Madrid Region, Spain.

    Since the middle of the 20th century, irrigation in the southeast of Spain has displayed significant productive growth based on the intensive use of the scarce water resources in the area and the contribution of river flows from the hydrographic basin of the Tagus River to the hydrographic basin of the Segura River. Despite high levels of efficiency in the water use from the new irrigation systems, the water deficit has only intensified in recent years.

    In the last decade, efforts to re-localize the food system have been gaining ground in a way that is intended to induce changes in the primary sector, thereby improving its conditions and sustainability. The European Union has identified food as one of the ten key sectors with outstanding potential for an ecological transition, and public procurement of (organic) food as an appropriate policy to foster agricultural development and support small farmers.

    Nine Latin American countries plan to use silvopastoral practices—incorporating trees into grazing lands—to mitigate climate change. However, the cumulative potential of scaling up silvopastoral systems at national levels is not well quantified. Here, we combined previously published tree cover data based on 250 m resolution MODIS satellite remote sensing imagery for 2000–2017 with ecofloristic zone carbon stock estimates to calculate historical and potential future tree biomass carbon storage in Colombian grasslands.
