Regreening Africa: A bottom-up transformation of degraded lands

Reports & Research
Noviembre, 2020
África

It is estimated that 20% of global land is either degraded or undergoing degradation, leading to an annual loss of 12 million hectares of productive land (UNCCD 2017). In Africa, some 715 million ha are degraded, including 65% of all arable land, 30% of all grazing land and 20% of all forests. This is due to increasing populations, poor land management, institutional challenges and climate change (Gnacadja and Wiese 2016).

Prescribed Burning as A Management Tool to Destroy Dry Seeds of Invasive Conifers in Heathland in Denmark

Peer-reviewed publication
Octubre, 2020

Denmark

Non-indigenous conifers are considered invasive to the coastal dune heathland in Denmark, and massive clearing is carried out in an attempt to recreate and keep the original heathland. Burning is a common method for managing, but its feasibility to control the seed bank of conifers has not been investigated. This project shows that the burning of logged conifer trees will often eliminate seeds of lodgepole pine, mugo pine and Sitka spruce, even when the seeds were placed into a depth of five centimeters in the soil.

Carbon Storage Potential of Silvopastoral Systems of Colombia

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.

Bentonite-Based Organic Amendment Enriches Microbial Activity in Agricultural Soils

Peer-reviewed publication
Agosto, 2020
Global

Bentonite-based organic amendments may have the potential to enhance soil microbial properties. The experiment was carried out from 2014 to 2017 comprising four treatments: NPK fertilizer (nitrogen, phosphorus and potassium mineral fertilizer as a control), NPK + cattle manure, NPK + bentonite, and NPK + combination of manure with bentonite (MB) to verify this hypothesis.

People-Centric Nature-Based Land Restoration through Agroforestry: A Typology

Peer-reviewed publication
Agosto, 2020
Global

Restoration depends on purpose and context. At the core it entails innovation to halt ongoing and reverse past degradation. It aims for increased functionality, not necessarily recovering past system states. Location-specific interventions in social-ecological systems reducing proximate pressures, need to synergize with transforming generic drivers of unsustainable land use. After reviewing pantropical international research on forests, trees, and agroforestry, we developed an options-by-context typology. Four intensities of land restoration interact: R.I.

Legal guide on land consolidation

Land consolidation is a highly effective land management instrument that allows for the improvement of the structure of agricultural holdings and farms in a country, which increases their economic and social efficiency and brings benefits both to right holders as well as to society in general. Since land consolidation gives mobility to land ownership and other land rights, it may also facilitate the allocation of new areas with specific purposes other than agriculture, such as for public infrastructure or nature protection and restoration.

Консолидация земель - это высокоэффективный инструмент управления земельными ресурсами, который позволяет улучшить структуру сельскохозяйственных угодий и ферм в стране, что повышает их экономическую и социальную эффективность и приносит пользу как правообладателям, так и обществу в целом. Поскольку консолидация земель дает мобильность землевладению и другим правам на землю, она также может способствовать выделению новых территорий с особыми целями, отличными от сельского хозяйства, например, для общественной инфраструктуры или охраны и восстановления природы.

Targeting SLM technologies across landscapes: a framework to facilitate matching SLM technologies with landscape conditions and generate evidences

Diciembre, 2019
Global

The aim of this report is to develop a detailed framework that can guide the placement of land restoration options where they can be more effective so that the right ‘places’ are targeted and the appropriate technologies are used. The framework will also form the basis towards developing a decision support tool that can be used to accomplish processes and steps of landscape restoration (Fig. 1). The framework details the steps from diagnosis to identify hotspot areas of intervention, characterize those hotspots to assess potentials, constraints and current status.
