    REDD+ social safeguards have gained increasing attention in numerous forums. This paper reviews the evolution of multi-level policy dialogues, processes, and actions related to REDD+ social safeguards (e.g., Cancun Safeguards 1–5) among policy makers, civil society organizations, and within the media in Brazil, Indonesia and Tanzania, three countries with well advanced REDD+ programs. We find that progress on core aspects of social safeguards is uneven across the three countries. Brazil is by far the most advanced having drafted a REDD+ social safeguards policy.

    Appropriation of public lands associated with agricultural frontier expansion is a longstanding occurrence in the Amazon that has resulted in a highly skewed land-tenure structure in spite of recent state efforts to recognize tenure rights of indigenous people and smallholders living in or nearby forests. Growing concerns to reduce environmental impacts from agricultural development have motivated state governments to place greater attention on sustainable land management and forest conservation.

    El pastoreo o su exclusión, altera el banco de semillas en pastizales. Se analizó el efecto del pastoreo sobre el banco de semillas de la estepa de halófitas de un pastizal de la Pampa Deprimida. Los tratamientos fueron: 1) Pastoreo continuo con alta intensidad (C); 2) Pastoreo rotativo por 3 años con intensidad moderada (con historia de pastoreo continuo) (PR); y 3) Clausurado al pastoreo por 12 años (Cl), en Vieytes, Buenos Aires. Los muestreos se realizaron en febrero (Banco de Semillas Invernal: BSI) y en junio (Banco de Semillas Estival: BSE).

    El objetivo de este trabajo fue evaluar la emergencia de Eryngium horridum Malme (caraguatá), a partir de las semillas presentes en el banco de suelo de un pastizal templado de la Argentina, en el partido de Magdalena. Se seleccionó un sitio con alta densidad de la maleza, antes de que comenzara la diseminación natural de las semillas de E. horridum (principios de febrero), y se armaron seis parcelas de 50 cm de ancho y 150 cm de largo, una al lado de la otra; en tres parcelas se realizaron las mediciones de otoño y en las otras tres, en primavera.

    En Aisén, Chile, se compararon distintos estadios de degradación antropogénica de la vegetación arbustiva original en una serie de distintos manejos de pastoreo, utilizando los indicadores ecológicos vegetales de Ellenberg para los factores de luz, temperatura del aire y de reacción, nitrógeno y humedad del suelo. El matorral de ñirre primario se consideró como inicio de la serie. Se trabajó con tablas de vegetación separadas para cada estado de degradación.

    Although Climate-Smart Agricultural (CSA) practices are expected to boost adaptive capacity, food security and climate change mitigation in resource poor, smallholder farming systems, the barriers that can restrict its uptake are diverse. This study investigated the barriers hindering CSA practice adoption in the Santander department of Colombia as well as farmer perceptions of practice benefits and disadvantages.

    In the absence of clear international policy signals and strong global agreements on climate change and sustainable agriculture, countries are moving forward to test sustainability strategies through innovative policies and financing programmes. This paper explores how three countries – Brazil, Ethiopia, and New Zealand – are using integrated policy approaches to address the linked challenges of climate change, unsustainable agriculture, and food insecurity.

    Grassland primary productivity is the function that underpins the majority of the fodder production in cattle-rearing silvopastoral farms. Hence, understanding the factors that determine grassland productivity is critical for the design and management of silvpastoral systems. We studied the effect of two factors with documented impact on grassland productivity in seasonally dry silvopastures of Nicaragua, rainfall and trees.

    Argentine

    Land abandonment is a major issue worldwide. In Argentina, the Monte Desert is the most arid rangeland, where the traditional conservation practices are based on successional management of areas excluded to disturbances or abandoned. Some areas subjected to this kind of management may be too degraded, and thus require active restoration. Therefore, the aim of this study was to assess whether passive succession-based management is a suitable approach by evaluating the status of land degradation in a protected area after 17–41� years of farming abandonment.

    Twenty years ago I completed my Master’s work in the Chaco forests of northern Argentina. The native forests are, in fact, rangelands. In addition to livestock grazing, there is timber extraction, wildlife harvest (think tegu lizard cowboy boots), and charcoal production. I took part in a project comparing biodiversity among production systems. A new system promised to reverse biodiversity loss and soil degradation. But it’s a moot point now since much of that forest has been cleared for cropland—the highest rate of tropical forest loss in the world.
