    Recurrent Neural Networks (RNNs), including Long Short-Term Memory (LSTM) architectures, have obtained successful outcomes in timeseries analysis tasks. While RNNs demonstrated favourable performance for Land Cover (LC) change analyses, few studies have explored or quantified the geospatial data characteristics required to utilize this method. Likewise, many studies utilize overall measures of accuracy rather than metrics accounting for the slow or sparse changes of LC that are typically observed.

    Analyzing multi-scale changes in landscape connectivity is an important way to study landscape ecological processes and also an important method to maintain regional biodiversity. In this study, graph-based connectivity was used to analyze the dynamics of the connectivity of natural habitats in the Long Yangxia basin of upper Yellow River valley from 1995 to 2015. We used the core areas of the nature reserves as the source regions to construct ecological networks under different thresholds, so as to identify key areas that can maintain overall landscape connectivity.

    大约三年前,各国领导人就联合国《2030可持续发展议程》及其17个可持续发展目标达成一致,自此该议程和目标成为指导全球发展政策的核心框架。本版《世界森林状况》旨在加强我们对森林及其可持续经营如何为实现多项可持续发展目标做出贡献的理解。对世界森林而言,时间紧迫:我们必须开展跨部门协作,把利益相关方集合起来,尽快采取行动。《2018年世界森林状况》确定了可采取的行动,以增强森林和树木为加快实现可持续发展目标所必需做出的贡献。现在必须采取措施以更有效地与私有部门合作,必须对非正规部门进行改革,以实现更广泛的经济、社会和环境效益。七十年前,当联合国粮农组织完成其第一次世界森林资源评估的时候,主要关注在于是否有足够的木材来满足全球需求;而现在,我们则认识到森林和树木具有更为显著的全球意义。《2018年世界森林状况》第一次就森林和树木对景观和生计的贡献进行了评估。本报告目的是让更多读者了解森林和树木对人类、地球和子孙后代的重大意义。

    There are numerous global, regional, national and even subnational targets for increasing forest area and forest restoration. In light of these global targets and emerging ambitious national commitments, it is imperative to develop low-cost strategies and techniques for landscape restoration. The most widely used restoration strategies involving planting of tree seedlings are often costly and their application for restoring vast expanses of degraded forest lands in the region may be limited.

    Soil loss is a major threat to agricultural development in Malawi, and the size of the agricultural sector in the Malawian economy renders it a major limitation to the overall economic development of the country. Soil loss reduces cultivable soil depth, but also takes away fertile soils from farmlands. The net effect is a loss of agricultural productivity, increased expenditure on fertilizers, and a general decline in profitability of crop production.

    Given its wide scope on the work on forests, FAO requests information from its member countries in many different ways, using various reporting formats and questionnaires. The collected information is used to produce several outputs such as databases, overviews, reports, case-studies and other analyses. Below the flow of information from countries to FAO is sorted in two main categories: 1. Regular reporting requests and 2. Other reporting requests. The regular reporting requests contain information regularly reported by countries to FAO.

    The zero-deforestation movement has gained considerable momentum as governments and companies enter into commitments to curb deforestation. The most innovative are multi-stakeholder initiatives, where governments and international organi- zations have joined with the private sector and civil society organizations in making commit- ments to reduce deforestation. These pledges have created opportunities for improved forest governance by envisaging the private sector at the centre of the movement.

    Available evidence indicates that pastoral destitution in Ethiopia is principally driven by feed and water scarcity. Feed resources ought to be considered in the broader perspective and not predominantly during emergency as is the case now. Feed inventory and balance is therefore requisite such that the country is aware of its needs, resource availability, gaps, implications and how the gap can be filled within the country. This will make feed interventions in the country effective in the immediate, medium and long term as well as provide solutions for replication in the region.

    L’objectif du présent rapport est d’offrir un cadre conceptuel permettant de faire face aux problèmes de sécurité alimentaire dans une situation de pénurie d’eau pour l’agriculture. Il a été préparé par une équipe de spécialistes de la FAO et de consultants dans le cadre du projet «Faire face à la pénurie d’eau – le rôle de l’agriculture», et a été examiné à l’occasion d’une réunion de consultation des experts organisée à la FAO, Rome, du 14 au 16 décembre 2009 sur le même sujet.
