Introduction

 

Integrated weed management is considered one of the most attractive options for crop protection. It entails a proper choice of compatible measures (cultural, mechanical, biological and chemical) so that the components complement each other in keeping the weed population at manageable levels. However, in order to be effective, integrated weed management should build on knowledge of weed biology and ecology which in turn requires the specific weed species to be known. The lack of awareness, timely information and knowledge of the weeds limits the actual implementation of integrated weed management at the farmers’ level.

Project Abstract

 

Rice is one of the major cereals consumed in Africa and the rate of consumption is steadily increasing. Major concerns for the regional rice sector are (i) Rice production does not keep pace with increasing consumption rates and (ii) Rice prices on the international market are increasing. Africa is heavily dependent on the international market for rice since it imports around 10 million tonnes every year to meet its ever growing demand. Even after a better production in 2008, Africa is still estimated to import 9.3 million tonnes of rice from other parts of the world to feed its people. (Rice Market Monitor, FAO, Feb. 2009). East and West Africa are the main rice-producing sub-regions accounting for 95% of the total rice produced in Sub-Saharan Africa (SSA). The rice-cropping systems are rain-fed upland and rain-fed and irrigated lowland. Lowland rice production systems (both irrigated and rain-fed) account for 52% of the total area under rice in SSA.

Description of the work:

 

The project aims at creating a first network of West and East-African and European partners interested in sharing their knowledge in applied computer science for agriculture, and of the preparation of a knowledge base for identifying and controlling the major weeds of the rice crops. The project work plan is divided into 4 overlapping activities over a period of 3 years:

Objectives

 

The proposed action aims to contribute towards enhancing the productivity of rice-cropping systems and help improve food security in sub-Saharan Africa. Rice cropping systems suffer from significant production losses due to weed infestations. The action aims to create a science and technology module addressing the farming, extension and research community to foster appropriate and better weed management practices eventually resulting in increased productivity and therefore improved food security in the region.
