Sugarcane Yield

One way to use climate services in the case of sugarcane is to develop models that forecast yields to help the sector to be better prepared against climate risks. In this study, several models for forecasting sugarcane yields were developed and compared in the north of Ivory Coast (West Africa). These models were based on statistical methods, ranging from linear regression to machine learning algorithms such as the random forest method, fed by climate data (rainfall, temperature); satellite products (NDVI, EVI from MODIS Vegetation Index product) and information on cropping practices. The results show that the forecasting of sugarcane yield depended on the area considered. At the plot level, the noise due to cultivation practices can hide the effects of climate on yields and leads to poor forecasting performance. However, models using satellite variables are more efficient and those with EVI alone may explain 43% of yield variations. Moreover, taking into account cultural practices in the model improves the score and enables one to forecast 3 months before harvest in 50% and 69% of cases whether yields will be high or low, respectively, with errors of only 10% and 2%, respectively. These results on the predictive potential of sugarcane yields are useful for planning and climate risk management in this sector.

Jihadist expansion into West Africa will take time

Significance While the overall number of incidents is fewer than a dozen since the rise of the region's jihadist insurgencies in the early 2010s, the trend lends credence to growing warnings about the jihadist threat to coastal West African countries. Concern has focused on Ivory Coast and Benin, but there is also nervousness about Ghana, Togo and even Senegal. Impacts Western governments will boost security assistance to coastal states. Intelligence sharing and joint operations will not forestall cross-border hit-and-run attacks. Most regional states will resort to security-focused responses whose abuses drive jihadist recruitment.

Guinea, also sometimes referred as Guinea-Conakry, is found in West Africa. It is bordered by Guinea-Bissau, Senegal, and Mali in the north and Sierra Leone, Liberia, and Ivory Coast in the south. In 2016, Guinea had a population of 12.6 million over a territory of 245 860 square kilometres (km). Its capital and largest city is Conakry. The official language of Guinea is French, and the currency used is the Guinean franc (GNF).

Burkina Faso is a landlocked country in West Africa, surrounded by six countries: Benin, Ghana, Ivory Coast, Mali, Niger, and Togo. It has an area of 274,200 square kilometres (km) and has a population of 18.6 million inhabitants. Its capital is Ouagadougou, where the biggest airport of Burkina Faso, Ouagadougou International Airport, is found. By 2021, a new airport should be operational at Dosin, located 30 km north from the capital. Having no access to the sea, Burkina Faso relies on the ports of its neighbouring countries for its commercial exchanges. Eighty per cent of the external trade of Burkina Faso is conducted by sea. The main ports available to Burkina Faso are Cotonou, Lomé, Téma, Takoradi, and Abidjan. In practice, the autonomous port of Abidjan is the main port of maritime entry and exit into Burkina Faso, having regained its lost market share caused by the crisis in Ivory Coast in September 2002. International roads link Ouagadougou to all neighbouring ports and a railway line operates between Ouagadougou and Abidjan.

Mite Genus

A new monotypic genus, Ivoria taiensis gen. nov., sp. nov. (Mesostigmata: Uropodina: Uropodinychidae) is described on the basis of seven females collected in soil samples from Ivory Coast. The new genus has large and robust chelicerae, but it differs from the other Uropodina genera having similar chelicerae in several characters, which are presented in a comparative table. The new genus is placed in the family Urodinychidae based on its long setae h1, chelicerae with an internal sclerotized node, fixed digit of chelicerae apically smooth and devoid of apical processes, corniculi smooth.
