El año 2015 marcó un giro decisivo para la comunidad internacional del desarrollo. Si bien aún persisten retos inmensos, la culminación de los Objetivos de Desarrollo del Milenio puso de relieve los impresionantes logros alcanzados desde 1990: tanto la extrema pobreza, como la mortalidad infantil y el hambre se redujeron a casi la mitad.

Land degradation and soil erosion have emerged as serious challenges to smallholder farmers throughout southern Africa. To combat these challenges, conservation agriculture (CA) is widely promoted as a sustainable package of agricultural practices. Despite the many potential benefits of CA, however, adoption remains low. Yet relatively little is known about the decision-making process in choosing to adopt CA. This article attempts to fill this important knowledge gap by studying CA adoption in southern Malawi.

2015年对国际社会而言是具有分水岭意义的一年。联合国千年发 展目标于2015年到期；自1990年以来，世界各国在实现千年发 展目标方面取得了重大的进展，极端贫困人口、儿童死亡率以及饥 饿人口比例均降低了约一半。然而，我们仍然面临着巨大的挑战。 《2016全球粮食政策报告》综述了影响2015年及未来的食物安全和 营养的主要趋势、事件和变化，并探讨了全球食物系统如何在为进 一步减少饥饿、营养不良和贫困做出最优贡献的同时，确保全球资 源的可持续利用。2016年是我们将新的国际和国家承诺转化为行动 的重要的一年。

كان عام 2015 لحظة فارقة لمجتمع التنمية الدولية. فلقد ابرزت نهاية الاهداف
الانمائية للألفية التقدم الملحوظ والمحقق لتلك الاهداف منذ عام 1990 ، حيث
انخفضت معدلات الجوع والفقر المدقع ووفيات الأطفال إلى النصف، ومع ذلك تظل هناك
تحديات جسيمة. يستعرض تقرير السياسة الغذائية العالمية لعام 2016 الاتجاهات والاحداث
والتغيرات الكبرى التى تؤثر على الأمن الغذائي والتغذية في عام 2015 وما بعدها؛ كما
يناقش كيف يمكن للنظام الغذائي العالمي أن يساهم فى المزيد من خفض معدلات حدة الفقر،
والجوع، وسوء التغذية مع ضمان الاستخدام المستدام لموارد العالم. وسوف يكون عام 2016

Assessment of the progress of the Aichi Biodiversity Targets set by the Convention on Biological Diversity (CBD) and the safeguarding of ecosystems from the perverse negative impacts caused by Reducing Emissions from Deforestation and Forest Degradation Plus (REDD+) requires the development of spatiotemporally robust and sensitive indicators of biodiversity and ecosystem health. Recently, it has been proposed that tree-community composition based on count-plot surveys could serve as a robust, sensitive, and cost-effective indicator for forest intactness in Bornean logged-over rain forests.

Assessment and reporting of changes in vegetation condition at site and landscape scales is critical for land managers, policy makers and planers at local, regional and national scales. Land management, reflecting individual and collective values, is used to show historic changes in ecosystem structure, composition and function (regenerative capacity). We address the issue of how the resilience of plant communities changes over time as a result of land management regimes.

The limited amount of studies addressing the long‐term effectiveness of restoration actions to combat land degradation is a constraint for current landscape restoration planning and implementation. Remote sensing data provide a unique opportunity for gathering information on the spatial and temporal variability of restoration processes and may contribute to fill this knowledge gap.

The flow–sediment relationship is important to understand the soil erosion and land degradation processes in severe eroded areas. This study researches on variations of streamflow, sediment load, and flow–sediment relationship on multi‐temporal scales (annual, flood season and, monthly scales) in a highly erodible catchment of Chinese Loess Plateau.

Runoff is the key factor to understand the land degradation causing high risk of soil erosion and can reduce the water available for human societies and ecosystems. The dynamics of runoff and suspended sediment transport are not completely understood. In this study, we examined the trends, breaking point and regime changes for the runoff and sediment load at different temporal scales using 50 years of continuous observational data from a highly erodible sub‐catchment with an area of 7,325 km² in the Beiluo River basin on the Loess Plateau, China.

Desert rangelands are characterised by low and highly variable rainfall regime, low forage production and high heterogeneity in the distribution of natural resources. This study was carried out in the desert rangelands of Tunisia to evaluate the response of different rangelands to annual rainfall in terms of aboveground net primary production (ANPP) and rain use efficiency over a 10‐year period (2003–2012). In general, ANPP values were relatively low (123 kg DM ha⁻¹ y⁻¹) but would tend to increase with increasing annual rainfall for all rangeland types.

The Member States of the European Union have committed to the maintenance and protection of forest lands. More precisely, the Member States aim to ensure the sustainable development and management of the EU's forests. For 2013, Eurostat's statistics about primary and secondary wood products in the European forest land (65% thereof privately owned) estimate a roundwood production of 435 millionm3 in total. Harmonised information, i.e., spatially and temporarily differentiated, on forestry and wood harvesting activities in the European forests are missing however.

QUESTION: The decline and loss of perennial vegetation in dryland ecosystems due to global change pressures can alter ecosystem properties and initiate land degradation processes. We tracked changes of perennial vegetation using remote sensing to address the question of how prolonged drought and land‐use intensification have affected perennial vegetation cover across a desert region in the early 21st century? LOCATION: Mojave Desert, southeastern California, southern Nevada, southwestern Utah and northwestern Arizona, USA.
