It helps farmers to better anticipate risks and choose timely alternative options that can allow them to generate more profit. This study assesses the impacts of the use of climate information and services that benefit end-users. Individual surveys and focus groups were conducted with a sample of 368 people in eight communes in Southwestern Niger. The survey was conducted within the framework of the ANADIA project implemented by the National Meteorological Direction (NMD) of Niger. The survey aims to identify different types of climate services received by communities and evaluates the major benefits gained from their use. Mostly, the communities received climate (73.6%) and weather (99%) information on rainfall, temperature, dust, wind, clouds, and air humidity. Few producers in the area (10%) received i...

However, improving the production of this crop can help to ensure food security. Knowledge of Bambara groundnut's diversity will allow its use in breeding programs. This study concerns the agro-morphological characterization in the Sahelian agroclimatic zone of fourteen (14) morphotypes of Bambara groundnut identified in the Nigerien accessions collection. The data used are collected through an agronomic test using a complete random block design, with four repetitions. Twelve (12) characters including 01 phenological, 08 morphological and 03 related to the yield components at harvest were evaluated. Descriptive statistical analysis showed that the coefficients of variation ranged from 10.3% (early flowering) to 72% (seeds weight per plant). Significantly high values (CV> 20%) were observed for 07 characters out of 12 analyzed. Agromorphological characterization revealed significant differences between the 09 parameters of the morphotypes. It was found that the Ne-10 and Ne-14 morphotypes are more efficient in grain yield, with 10.8 and 9.6 g / plant, respectively. Late-flowering morphotype (Ne-01) had the lowest yield. Strong correlations were observed in the morphological parameters, with r = Ne-07 Rouge clair Un peu partout, en mélange et en quantité faible Ne-08 Marron clair Un peu partout, en mélange et en quantité faible Ne-09 Jaune tacheté de noir avec oeil en forme de papillon, coloré en marron Un peu partout, en mélange et en quantité faible Ne-10 Jaune avec petits points marron sur le tégument, oeil marron Rare, toujours en mélange et en petite quantité, facilement rencontré dans le Manga Ne-11 Jaune avec un ou deux traits marron et oeil noir Un peu partout, en mélange et en quantité faible Ne-12 Grosses graines et rouge claire Rare et se trouve en petite quantité Ne-13 Jaune fortement coloré en noir avec oeil marron Un peu partout, en mélange et en quantité faible Ne-14 Grise tachetée à oeil bronzé Un peu partout, en mélange et en quantité faible

As a consequence, bad rainy seasons have a massive impact on crop yield and regularly result in food crises. Traditional insurance policies based on crop damage assessment are not available because of asymmetric information and high transaction costs compared to the value of production. We assess the risk mitigation capacity of an alternative form of insurance which has been implemented at a large scale in India since 2003: insurance based on a weather index. We compare the efficiency of various weather indices to increase the expected utility of a representative risk-averse farmer. We show the importance of using plot-level yield data rather than village averages, which bias results due to the presence of idiosyncratic shocks. We also illustrate the need for out-of-sample estimations in order to avoid overfitting. Even with the appropriate i...

Indeed, SSA is the region at greatest food security risk because by 2050 its population will increase 2.5-fold and demand for cereals approximately triple, whereas current levels of cereal consumption already depend on substantial imports. At issue is whether SSA can meet this vast increase in cereal demand without greater reliance on cereal imports or major expansion of agricultural area and associated biodiversity loss and greenhouse gas emissions. Recent studies indicate that the global increase in food demand by 2050 can be met through closing the gap between current farm yield and yield potential on existing cropland. Here, however, we estimate it will not be feasible to meet future SSA cereal demand on existing production area by yield gap closure alone. Our agronomically robust yield gap analysis for 10 countries in SSA using loca...

A l'instar des autres céréales pluviales, cette culture reste tributaire des conditions agro-climatiques et phytosanitaires très aléatoires dans la zone. Dans le but de proposer de bonnes techniques d'adaptation du mil face aux variabilités climatiques, les effets de la transplantation (précoce et tardive) de jeunes plants ont été testés sur la croissance et le développement de trois variétés de mil à savoir HKP (cycle de 90 jours), Sounna 3 (cycle de 105 jours) et Somno (photopériodique). Les résultats obtenus ont montré que la transplantation des plants, préalablement cultivés en pépinière, pendant environ un mois avant la date de début de la saison des pluies et transférés au champ dès la première pluie utile (≥ 15mm), a permis de réduire significativement la durée de la croissance végétative des plants au champ (notamment la durée du stade tallage). Elle a également permis d'augmenter les rendements en pailles et en grains des variétés à cycles courts (HKP et Sounna 3), par rapport au traitement témoin. Quant au traitement de la transplantation tardive de plants issus d'une pépinière mise en place le jour de la première pluie utile, elle a entrainé une réduction des rendements en pailles et en grains de toutes les variétés testées, sans avoir un effet significatif sur la durée des phases phénologiques. De par les résultats obtenus, on peut déduire que cette technique est assez prometteuse pour accroitre la production du mil dans le contexte de variabilités climatiques au Sahel. Abstract Pearl millet is the most widely grown food crop in the Sahel in general and in Niger in particular. Like other rainfed cereals crops, it remains dependent on the very unpredictable agro-climatic and phytosanitary conditions in the area. In order to propose good millet adaptation strategies to climatic variability, the effects of early and late transplantation of seedlings were tested on the growth and development of three millet varieties, namely HKP (cycle duration of 90 days), Sounna 3 (cycle duration of 105 days) and Somno (photoperiod sensitive). The results showed that, the transplantation of seedlings, initially grown in a nursery for about one month before the start date of the rainy season and transferred to the field after the first useful rainfall event (≥ 15 mm), significantly reduced the duration of vegetative growth period (in particular the duration of the tillering phase). It also increased straw and grain yields of short cycle varieties (HKP and Sounna 3) compared to the control. As for the treatment of late transplantation of seedlings from a nursery set up on the day of the first useful rain, it resulted in a reduction in straw and grain yields of all the varieties tested, without having a significant effect on the duration of the phenological phases. From these results, it can be deducted that, this technique is a promising strategy for adapting the millet to climate variability in the Sahel.
