Papua New Guinea is a country in Oceania that hosts unique rain forests and forest ecosystems which are crucial for sequestering atmospheric carbon, conserving biodiversity, supporting the livelihood of indigenous people, and underpinning the timber market of the country. As a result of urban sprawl, agricultural expansion, and illegal logging, there has been a tremendous increase in land-use land cover (LULC) change happening in the country in the past few decades and this has triggered massive deforestation and forest degradation.

Agroforestry, as the dominant land use at the volcanic foot slope in Java Island, is prone to landslide due to a combination of rough relief and thick soil layer. However, evaluations of specific vegetation patterns against landslide reactivation due to soil erosion, which relays on the existing slope units and geomorphological processes, are still limited. The research data were collected through aerial photo interpretation by delineating morphological units of old landslides, slope units, and the existing land use.

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.

Belowground roles of agroforestry in climate change mitigation (C storage) and adaptation (reduced vulnerability to drought) are less obvious than easy-to-measure aspects aboveground. Documentation on these roles is lacking. We quantified the organic C concentration (Corg) and soil physical properties in a mountainous landscape in Sulawesi (Indonesia) for five land cover types: secondary forest (SF), multistrata cocoa–based agroforestry (CAF) aged 4–5 years (CAF4), 10–12 years (CAF10), 17–34 years (CAF17), and multistrata (mixed fruit and timber) agroforest (MAF45) aged 45–68 years.

In Thailand, COVID-19 has made life harder for communities, many of which are already facing droughts, stagnant wage growth and rising poverty. Poverty rates had already risen in 2016 and 2018 in Thailand, according to the World Bank.  Now, with large parts of the economy shuttered or slowed because of the crisis, poor families are struggling as incomes vanish.

Por investigaciones anteriores de WRI, sabemos que las tasas de deforestación en tierras indígenas de laAmazonía son considerablemente más bajas que entierras no administradas por pueblos indígenas. Ahora,hemos aprendido por este informe, que la minería industrial y la minería ilegal a pequeña escala se produceen más del 20 por ciento de las tierras indígenas de laAmazonía y que las tasas de deforestación en tierras indígenas donde existe minería son signi cativamente más altas que en las tierras indígenas sin minería.

Land in Cameroon is under growing pressure – powerful commercial interests;changing climate conditions and shifting demographic flows including mass migration and increasing population density. The rights of rural communities and indigenous people to access and use land for farming and grazing have been eroded,  primarily due to failure to recognise customary land tenure rights;land use conflicts and lack of effective local governance. The country’s land legislation is outdated and not compatible with customary law and local realities.

A nine-minute video. Most rural people in Uganda have rights to their rural land through customary tenure arrangements;representing 75-80% of land holdings: but only 15-20% of the land is formally registered. Often women;especially widows;experience land grabbing;arbitrary eviction and poor access to justice. GLTN and others are working to help vulnerable smallholder farmers in South Western and Elgon regions through the implementation of a ‘Securing Land Tenure for Improved Food Security in select areas in Ugandaproject. The video illustrates some of this work.

Location-specific forms of agroforestry management can reduce problems in the forest–water–people nexus, by balancing upstream and downstream interests, but social and ecological finetuning is needed. New ways of achieving shared understanding of the underlying ecological and social-ecological relations is needed to adapt and contextualize generic solutions. Addressing these challenges between thirteen cases of tropical agroforestry scenario development across three continents requires exploration of generic aspects of issues, knowledge and participative approaches.

Tree root systems stabilize hillslopes and riverbanks, reducing landslide risk, but related data for the humid tropics are scarce. We tested fractal allometry hypotheses on differences in the vertical and horizontal distribution of roots of trees commonly found in agroforestry systems and on shear strength of soil in relation to root length density in the topsoil. Proximal roots of 685 trees (55 species; 4–20 cm stem diameter at breast height, dbh) were observed across six landscapes in Indonesia.

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.
