Conservation agriculture for the dry-land areas of the Yellow River Basin: Increasing the productivity, sustainability, equity and water use efficiency of dry-land agriculture, while protecting downstream water users

Reports & Research
Abril, 2010

China

Soil erosion is a major problem in the Yellow River Basin: the river is one of the most

sediment-laden in the world. Although there is a rainfall gradient from 750 mm in southern

Shandong, to 200mm per year in northern Ningxia, most of the rainfed cropping area is in

regions with more than 400 mm per year – it is here that the project concentrated.

Conservation agriculture (featuring reduced or zero tillage, mulch retention, crop rotations

and cover crops) offers a possible solution to problems of soil erosion and low crop

The global drylands imperative: pastoralism and mobility in the drylands

Reports & Research
Dezembro, 2002
Global

This document outlines the necessity of formulating development policies specifically targeted at pastoralists and their livelihoods. The author reports that pastoralists have generally been ill-served by development policies and actions because of myths suggesting that pastoralists were 'backward'. Previous policies focused on changing pastoralists into something more ‘modern' or progressive.

Tackling land degradation and desertification: GEF - IFAD partnership

Dezembro, 2001
Global

Desertification occurs in drylands,which span a third of the earth ’s land surface in over 110 countries.It influences the lives of about 500 000 people – the so-called environmental refugees –including many of the world ’s poorest and most marginalized populations. Each year 12 million hectares (ha)are lost to deserts.That is enough land to grow 20 million tonnes of grain.

People in marginal drylands. Managing natural resources to improve human well-being

Journal Articles & Books
Dezembro, 2008
Global

Change in land management practices and governmental policies is urgently needed to reverse the continuing decline of marginal drylands. Marginal drylands are fragile ecosystems that sustain the livelihoods of millions of poor people in developing countries. However, their capacity to provide these services is continuously declining due to desertification, resulting in dwindling land productivity, and affecting human well-being and development opportunities in many marginal drylands.

It took scientists more than three decades to transform a perceived desertification crisis in the Sahel into a non-event. Looking beyond the Sahel, the chapters in this book provide case studies from around the world that examine the use and relevance of the desertification concept.

Salinization in Drylands

Global

Most commonly in drylands the salinity levels are always high and evenly dispersed due to this salinity levels the plant cultivated are usually tremendously affected. Normal plants cannot grow in soils with high salinity levels. In this book the authors would like to analyze the effects of human acticities on the salinity lebvels in drylands.

Scaling up regreening: Six steps to success. A practical approach to forest and landscape restoration

Journal Articles & Books
Dezembro, 2015
Global

In a world grappling with the challenges of food insecurity, climate change, landscape degradation, and rural poverty, regreening offers a path forward, especially in dryland areas. The transformation of degraded landscapes—restoring productivity and increasing resilience through the widespread adoption of agroforestry and sustainable land management practices—can deliver food, climate, and livelihood benefits.

Drylands occupy more than 40% of the world’s land area and are home to some two billion people. This includes a disproportionate number of the world’s poorest people, who live in degraded and severely degraded landscapes. The United Nations Convention to Combat Desertification states on its website that 12 million hectares are lost annually to desertification and drought, and that more than 1.5 billion people are directly dependent on land that is being degraded, leading to US$42 billion in lost earnings each year.

Two decades of farmer managed natural regeneration on the Seno plain, Mali. Included in Restoring African Drylands

The adoption of FMNR increased by 50% over 20 years; about 90% of all farmers now encourage natural regeneration on the land that they manage. The key to success is having local institutions that are respected and effective. The experience in Bankass shows that reforestation rates of at least 250 trees per hectare can be achieved by farmer managed natural regeneration on Sahelian agricultural lands, recreating an agroforestry parkland at a fraction of the cost of establishing conventional plantations.

Improving international soil governance – Analysis and recommendations. Final report

Global

This study develops options for the German government to improve international soil governance in the short, medium and long term. The study first takes stock of existing international instruments and institutions that are relevant for soil protection and its governance at the international level. It as-sesses the actual and potential steering effect of, inter alia, the Desertification Convention, the Biodiversity Convention, the Paris Agreement and climate regime, regional treaties, FAO, UNEP, IPBES and IPCC.

Land degradation states and trends in the northwestern Maghreb drylands, 1998–2008

States of ecological maturity and temporal trends of drylands in Morocco, Algeria and Tunisia north of 28 N are reported for 1998–2008. The input data were Normalized Difference Vegetation Index databases and corresponding climate fields, at a spatial resolution of 1 km and a temporal resolution of one month. States convey opposing dynamics of human exploitation and ecological succession. They were identified synchronically for the full period by comparing each location to all other locations in the study area under equivalent aridity.

Microbial biotechnology as a tool to restore degraded drylands

Journal Articles & Books
Novembro, 2017
Global

The authors briefly review how microbial biotechnology can contribute to improve activities aiming to restore degraded drylands and to combat their desertification, which are an integral part of the Sustainable Development Goal 15 of the 2030 Agenda. Microbial biotechnology offers notable promise to improve restoration actions based on the use of biocrust‐forming engineered cyanobacteria, which play key roles in maintaining ecosystem structure and functioning in drylands worldwide.
