GGW Agency To Check Desertification

The Vice President Namadi Sambo has said that the National Council  on Shelterbelt and Afforestation (NCSA) programme was aimed at reforming and revamping the ecology in order to save livestock and plants.

The vice president who spoke recently in Abuja at the fourth meeting of NCSA said there was already a draft bill for the establishment  of the Great Green Wall Agency with recommendation to the Federal Executive Council.

The vice president, who chaired the meeting warned against cultivation of land in order to attain the planned objective of the programme. He said such programmes has successfully been achieved, Senegal, Rwanda and Burundi even as he called the attentionof members of the NCSA to the fact that both the shelterbelt and the Great Green Wall (GGW) started on a slow note.

11 African Countries Are Building a “Great Green Wall of Africa” to Stop the Spread of the Sahara Desert

Sub-Saharan Africa has some of the best farmland and in the world. So naturally, the vast majority of food production in Africa takes place there.

However, the Sahara desert has been slowly spreading south, covering previously fertile lands with sand and absorbing them into the desert in a process known as desertification.  A UN report from 2007 estimated that if the desertification is left unchecked, 2/3 of Africa’s arable land will be covered with sand by the year 2025. It is this rapid spreading of the Sahara that inspired the idea for the Great Green Wall of Africa.

The Use of Pleiades and TerraSARX Imagery in Desertification and Coral Reef Mapping Projects in Morocco and Kuwait


The research reported in this poster relates to two doctoral research projects currently being undertaken at the University of South Australia. Project A (Alsharrah, Bouabid and Bruce) is focused on the use of high spatial resolution remote sensing to improve vegetation inputs to models for desertification and utilizes Pleiades, TerraSAR X, Rapideye, ASTER and Landsat imagery over an arid site on the slopes of the Atlas Mountains in Morocco. Project B (Gholoum, Alhazeem, Anderson and Bruce) concentrates on the use of high spatial resolution remote sensing to improve estimates of coral reef density for the Kubar coral reef system in Kuwaiti waters in the Arabian / Persian Gulf. In pr

oject B WorldView 2 (Multi-Spectral (MS)and Panchromatic (Pan)) imagery are being analyzedtogether with Pleiades-1B and Landsat imagery, and compared with quality field data to assess the accuracy of processing methods

UNCCD News Issue 6.1. Desertification and global security

The latest issue of UNCCD News is accessible at:


From the Executive Secretary
Land degradation – a security issue
Land degradation can turn into a security issue. That’s why investigating the connection between land degradation and conflict is high on the UNCCD’s agenda.

Land degradation exacerbates food insecurity, but may also contribute to forced migration, political instability, fragility and conflict. There is more to security than the political, economic and social dimensions.

Desertification: the invisible frontline

Syria’s conflict: Is land degradation part of the story?

Hartmut Behrend, a climatologist with the German Armed Forces, takes a look at the impact of environmental degradation on security with a focus on how NATO deals with these new challenges.

A contested link: environmental degradation and conflict
There is no scientific evidence proving that desertification, climate change and conflict interact. For some researchers, the correlation is obvious, whereas others refer to environmental stressors, threat multipliers or amplifiers. Some recent writings on the subject are provided.

Syngenta and UNCCD build partnership for a Soil Leadership

Syngenta today announced the signing of a Memorandum of Understanding (MOU) with the United Nations Convention to Combat Desertification (UNCCD) to establish and operationalize the Soil Leadership Academy.

The Academy aims to address the soil conservation challenge globally. It will engage research institutes, universities, and on-the-ground practitioners to share knowledge and expertise in soil conservation and sustainable land management. Policy makers and land users worldwide will have access to critical information and interactive training approaches such as simulation exercises, practical case studies, field demonstrations, videos, and smartphone apps.

A kitchen garden for work and “Seeds for Food” (Willem Van Cotthem)

Agroforestry and container gardening


Prof. Dr. Willem VAN COTTHEM
Honorary Professor University of Ghent (Belgium)
Beeweg 36 – BE 9080 ZAFFELARE (Belgium)

We have been discussing with colleagues and friends the need to link forestry and agriculture (agroforestry) in order to motivate local people in the drylands to do the fieldwork of a reforestation project by offering them first a family garden at the very start of the project.

Hungry people with an empty stomach don’t plant thousands of trees easily and with enthusiasm. We have never been in favor of ‘Food for Work’, because it is not changing the cause of hunger.  We would rather change it into ‘A Kitchen Garden for Work’.

The ‘Seeds for Food’ action is heading for a remarkable success ( and ‘Zaden voor Voedsel’ (  People from all over Europe, even from Canada and the USA, are nowadays sending us seeds of vegetables and fruit trees.  After proper treatment they are sent for free to different development projects in the drylands, e.g. to refugee camps, where people start constructing family (kitchen) gardens and school gardens.

We are convinced that people, in particular children, are strongly interested in container gardening.  We have published photo albums on Facebook about some simple experiments we did at home, growing avocado seeds in plastic bottles and yogurt pots:


We also produced a number of YOU TUBE films on this subject, e.g. Building a bottle tower for container gardening :

It is astonishing to see how visitors at home are amazed when looking at the wonderful aspects of developing seedlings in simple bottles or pots, not to mention the educational value of having all the stages of seedling development within hand reach. This should be done at every school. There is no better way to show youngsters the beauty of young trees and vegetables.

If ever we could convince all the school children of this world to grow some seedlings of fruit trees in pots and bottles at school, they could plant them at home or in the schoolyard and contribute to the greening of the earth.  Wouldn’t it be remarkable if one could find fruit trees growing everywhere?  Something to alleviate hunger starting from seeds in pots or bottles? Something to take care of our environment by collecting all the otherwise littered bottles and pots?

So, let us collect seeds in every country, seeds of vegetables, seeds of the fruits we are eating (normally thrown in the garbage bin or on the compost heap) and offer these “germs of new life” for free to the hungry of this world. Offering an opportunity to grow food crops in millions of family gardens and to grow fruit trees wherever we can plant them, is a straight way (an avenue, a highway!) to taking care of hunger, poverty and climate change. We are no dreamers, but scientists and social workers, tired of all that endless talking, talking, talking, but fit enough to offer full-heartedly their experience and expertise through supporting and participating in very practical actions.

Let’s reach hands to promote this inexpensive method.

Effects of desertification in Africa (Google / Yahoo)

What are the effects of desertification in Africa?

Desertification is the degradation of land in arid and dry sub-humid areas, resulting primarily from human activities and influenced by climatic variations. It’s also a failure of the ecological succession process. A major impact of desertification is biodiversity loss and loss of productive capacity, for example, by transition from land dominated by shrub lands to non-native grasslands.
