A water and soil quality baseline study was carried out across the ~ 4500 km2 Vientiane Plain in Lao PDR. Eight water quality and nine soil parameters were analysed using field kits at 95 sites in March 2015. Elevated electrical conductivity and chloride were apparent at two sites due to geogenic leaching from the marine rock-salt present in some areas. Groundwater was acidic in most locations. Nitrate and faecal contamination were also observed from nitrogenous fertilizers (diffuse) and from leaky sewage pits (localised) respectively.

O Assentamento Dois Riachões é composto por 38 famílias, com cerca de 170 pessoas e está situada no município de Ibirapitanga-BA no território Baixo Sul da Bahia no Bioma Mata Atlântica a 380 km da capital - Salvador. A Comunidade está organizada em associação, composta por uma coordenação colegiada, representantes da executiva (presidente, secretário e tesoureiro) e setores de produção (gênero, e

The papers in this volume take a city perspective and provide both a critical reflection of and a pragmatic response to what cities are able to do given their current mandate and powers. The first paper begins by considering what the TOD agenda means for the urban poor. It questions whether TOD can adequately address the existing land challenges in South African cities, given the politics of land inequality and the skewed property markets.

Widespread land degradation has serious negative ecological, social, and economic consequences. This is particularly true for smallholder farming systems in sub-Saharan Africa, which are crucial for the livelihoods of the majority of the population and the national economies. Sustainable land management (SLM) is seen as the best way to combat or even reverse land degradation. However, the contexts and conditions hindering land users’ uptake of SLM techniques are often poorly understood. The AGORA project explores the drivers of land degradation at two sites in Tanzania and Malawi.

Les Directives volontaires pour une gestion durable des sols ont été élaborées dans le cadre d’un processus ouvert, au sein du Partenariat mondial sur les sols. Elles visent à servir de référence et à fournir à un vaste éventail de parties prenantes engagées des recommandations générales d’ordre technique et stratégique concernant la gestion durable des sols.

The Voluntary Guidelines for Sustainable Soil Management (VGSSM) were adopted by the 4th GSP Plenary Assembly (Rome, 25 May 2016), approved by the 25th session of the FAO Committee on Agriculture (Rome, 28 September 2016) and finally endorsed by the 155th session of the FAO Council (Rome, 5 December 2016). These guidelines provide technical and policy recommendations on how sustainable soil management can be achieved. The successful implementation of these guidelines should pave the way to boost ing soil health

This handbook has been prepared for the training workshop on innovative methods of amelioration and use of salt-affected soils, which takes place in Kharkiv, Ukraine, in September 2017. This workshop is conducted within the framework of the Implementation Plan of the Eurasian Soil Partnership, which is a sub-regional affiliation of the Global Soil Partnership.

Smallholder irrigation expansion would signi cantly increase agricultural production, and reduce food insecurity and poverty levels in East Africa. This paper reviews literature on trends, constraints and opportunities of smallholder irrigation in four East African countries: Ethiopia, Kenya, Tanzania and Uganda. Irrigation development has been slow in these countries, and has been mainly through traditional schemes.

Policy objectives to maintain ecosystem services are increasingly set. Methods to identify priority areas for ecosystem services can assist in the implementation of such policy objectives. While land use change is an important driver of changes in ecosystem services over time, most prioritization studies do not account for land use change or only assess negative effects. We assessed the effect of land use change on ecosystem services in Europe for a 40-year period and the subsequent consequences for identifying priority areas. We quantified five services under current and future land use.
