Combating desertification

Through direct seeding mulch-based cropping systems (DMC)

Issue 4 40 pp. • Published in April 2006

Author(s): Raunet Michel, Naudin Krishna

Water and soil are the first links of the food chain of ecosystems, and these components in turn nurture the soil with their biomass. Desertification affects both of these key components with a series of consequences that ramify throughout the entire ecosystem, which thus becomes vulnerable, loses part of its biodiversity and hence its resilience and functions. These degraded ecosystems are no longer able to provide stakeholders— especially farmers—with resources and services. Farmers are then forced to overutilize the environment, thus further worsening the desertification process. What could be done to offset this desertification spiral at local and then at higher global scales?

Research and development on cropping systems such as direct-seeding mulch-based cropping systems (DMC) means at least partially meeting this challenge, and then disseminating this technique in Southern countries during the 21st century. DMC is a highly innovative system, central to conservation agriculture and agro-ecological practices. It involves no-till cropping and provides permanent soil protection with both crop residue and companion crops, through crop combinations, yearly sequences or rotations.

Dossiers

thématiques du CSFD

Mankind is now confronted with an issue of worldwide concern, i.e. desertification, which is both a natural phenomenon and a process induced by human activities. Our planet and natural ecosystems have never been so degraded by our presence. Long considered as a local problem, desertification is now a global issue of concern to all of us, including scientists, decision makers, citizens from both developed and developing countries. Within this setting, it is urgent to boost the awareness of civil society to convince it to get involved. People must first be given the elements necessary to better understand the desertification phenomenon and the concerns. Everyone should have access to relevant scientific knowledge in a readily understandable language and format.

Within this scope, the French Scientific Committee on Desertification (CSFD) has decided to launch a series entitled Les dossiers thématiques du CSFD, which is designed to provide sound scientific information on desertification, its implications and stakes. This series is intended for policy makers and advisers from developed and developing countries, in addition to the general public and scientific journalists involved in development and the environment. It also aims at providing teachers, trainers and trainees with additional information on various associated disciplinary fields. Lastly, it endeavours to help disseminate knowledge on the combat against desertification, land degradation, and poverty to stakeholders such as representatives of professional, nongovernmental, and international solidarity organisations.

These Dossiers are devoted to different themes such as global public goods, remote sensing, wind erosion, agroecology, pastoralism, etc, in order to take stock of current knowledge on these various subjects. The goal is also to outline debates around new ideas and concepts, including controversial issues; to expound widely used methodologies and results derived from a number of projects; and lastly to supply operational and academic references, addresses and useful websites. These Dossiers are to be broadly circulated, especially within the countries most affected by desertification, by email, through our website, and in print. Your feedback and suggestions will be much appreciated!
