“…However, the agricultural sector in Haiti faces several challenges, such as poor soil quality, limited irrigation, and deforestation, which have contributed to a decline in agricultural productivity. These challenges have made it difficult for Haiti to produce enough food to feed its population, leading to a heavy reliance on food imports (Wisner 2021, Jenkins 2022, Quellhorst et al 2020.…”

Global food price inflation has serious implication toward welfare and food and nutrition security in developing countries where most of the population are classified as low-income and are net-food importers. Haiti is one such nation which depend heavily on trade for food, making them extremely vulnerable to global food price increase. This study aims to investigate the welfare impact of rising global prices of imported food on Haitian consumers using annual data from 1980-2021. The LA-AIDS model was employed to estimate Hicksian price and income elasticities for the five major imported food categories, and compensating variation was used to assess the welfare impacts of rising global food prices on Haitian consumers. The study finds that all imported food categories were import price inelastic, except for meat which was price elastic. Cross-price elasticities indicated substitution and complementary relationships between various pairs of imported food categories. Income elasticities showed that demand for cereals and dairy was income inelastic, while demand for meat, vegetable oil, and sugar was income elastic. The welfare exercise revealed that price increases between 2006-2008, 2010-2013, and 2020-2021 resulted in welfare losses of around US$223.91 million, US$89.33 million, and US$458.50 million, respectively. It was also discovered that imported cereals and vegetable oil accounted for most of the lost welfare during the study periods. The results of this study provide valuable information for policymakers to develop policy intervention strategies that aims to safeguard the welfare of Haitian consumers.

“…Deterioration of grains after harvesting is a global issue and it commonly occurs during storage and transportation (García-Mosqueda et al, 2019;Xue et al, 2017). PHLs of grains are caused by pest infestation and microbial and rodents attacks (Mapfeka et al, 2019;Mezgebe et al, 2016;Quellhorst et al, 2020;Schmidt et al, 2018). The fungal attack is the most disastrous, and it causes losses and healththreatening problems in improperly dried grains (Garbaba et al, 2018).…”

“…The major factors account for PHLs of grains are infestation by insect-pests, rodents, imprudent store-time, unjustifiable marketing models (Swai et al, 2019), poor storage and transportation facilities (Janila et al, 2016;Swai et al, 2019;Tibagonzeka et al, 2018), spillage due to inadequate handling, transportation and packaging facilities, reused packaging materials (Mwangi et al, 2017), use of uncertified seeds (Njonjo et al, 2019), planting mixed variety of seeds, mixing old and new seeds, harsh weather conditions, farmers disunity, limited access to loans, inadequate on-farm storage facilities (Tibagonzeka et al, 2018), limited output, access to the market (Amentae et al, 2016), bad roads, annual average rainfall (Hengsdijk and de Boer, 2017), limited access to vital farm inputs (Gunasekera et al, 2017), lack of sufficient postharvest management intervention (Quellhorst et al, 2020;Fabi et al, 2021), lack of improved crop variety and inappropriate storage condition (Kumari et al, 2020).…”

Grains (cereals and legumes) are universal foods that provide calories, proteins, essential minerals and vitamins. They are essential to the nutrition of many including infants and children. Attack by insects and microorganisms, particularly fungi, during drying, storage and processing, affects the quality, safety and market value of grains. Fungal attacks before or during drying can be disastrous, the effect can persist throughout the supply chain. Postharvest grain losses pose challenges to food and nutritional security, public health, and many developing nations' economy. Postharvest storage structures and packaging materials are expected to extend the shelf life of the grains by protecting them from insects, microorganisms, environmental factors and making the microenvironment unfavorable for insect and microbial activities. Traditional storage and packaging materials are highly inefficient in this sense and are associated with quality degradation. Traditional storage and packaging materials commonly used by farmers, mostly in developing countries, include granary, crib, wooden box, gunny bag and polypropylene woven bag. Modern storage and packaging materials commonly used are metal silo and hermetic bags; they are effective but unfortunately cannot be afforded by most farmers in developing countries. The article reviewed postharvest storage management of cereals and legumes. Literature was gathered through a comprehensive literature review. The use of various traditional storage and packaging materials for grains was debated. Techniques for the prevention of postharvest losses were extensively discussed, emphasis was given to novel technology and the use of natural insecticides. Challenges associated with controlling postharvest losses were also summarised. In the end, research gaps were identified and recommendations were provided about minimizing grain contamination and postharvest losses.

“…It is typical of grain aggregators to store cowpea in non-ventilated storehouses in market areas, for periods up to six months. The quest for postharvest loss reduction and food safety requires in-depth knowledge on the comparative advantage of different alternatives which are harmless to the user, inexpensive, readily available, and indigenous to farmers, marketers and consumers of cowpea, given the recent push to reduce the use of synthetic pesticides in postharvest management of grains [34]. This study was therefore set up to carry out a comparative analysis of Vitellaria paradoxa seed oil and crude DE with respect to their storage efficacy on cowpea under ventilated and nonventilated conditions.…”

Storage of cowpea is highly constrained by insect pest infestation and losses caused by the cowpea weevil (Callosobruchus maculatus, F.) are high. Several methods have been used over the years to protect cowpea grains in storage, but the use of synthetic insecticides is very dominant and this has led to problems, such as the killing of non-target species, user hazards, harmful food residues, and evolution of resistance to chemicals. A search for alternative insect pest control methods which are relatively less harmful to the user and cheaper has become essential. The effectiveness of Diatomaceous earth (DE) and Vitellaria paradoxa seed oil (VPSO) for cowpea storage in polypropylene and jute bags under ventilated and non-ventilated storeroom conditions were investigated over three months period. Crude DE was applied at a dose rate of 1 g/kg of cowpea and a diluted concentration (10% v/v) of VPSO of 400 mL was mixed with 8 kg of cowpea. Live insect count, dead insect count, and germination percentage were assessed weekly while proximate analysis was carried out before and after storage. Mean live insect count increased in the ventilated store-room from 0.67±0.34 to 36.13±19.51insects/kg after 1 month and 3 months of storage respectively for untreated cowpea. Insect population in treated samples increased from 0.38±0.26to 24.78±23.33, and from 0.17±0.30 to 10.75±5.27 for DE and VPSO treated samples, respectively. In the non-ventilated storeroom, insect population increased from 0.33±0.26 to 36.96±19.09 for untreated cowpea, 0.17±0.20 to 33.08±30.07 for DE and 0.21±5.63 to 8.17±11.30 for VPSO treated cowpea. Based on insect count, both treatments were very effective in controlling cowpea weevil in the first two months of storage, however their potency reduced by the third month. The potency of DE deteriorated faster compared to VPSO however, DE treated cowpea was most effective for retaining seed germination in both ventilated and non-ventilated storerooms. Proximate analysis showed that cowpea treated with both treatments had similar nutrient composition after storage. Diatomaceous earth and Vitellaria paradoxa seed oil have potentials in their raw form for short term insect pest control in the storage of cowpea.
