“…Based on the Köppen-Geiger classification (Figure 1b), the climate in Mozambique is equatorial savannah with dry winters (Aw) with some areas having hot semi-arid climate (BSh), while higher-elevation regions have warm temperate climate with dry winters and hot summers (Cwa) [25]. In the Western part of Gaza, one of the driest regions of the country, the yearly rainfall is around 200 mm, while in the Zambezia province, the annual rainfall is around 1200 mm [26]. In most parts of Mozambique, more than 90% of the annual rainfall occurs from November to March while less than 10% occurs from April to October.…”

Irrigation scheduling is used by growers to determine the right amount and timing of water application. In most parts of Mozambique, 90% of the total yearly precipitation occurs from November to March. The El Niño Southern Oscillation (ENSO) phenomenon influences the climate in Mozambique and affects the water demand for crop production. The objectives of this work were to quantify the effects of ENSO phenomenon on tomato crop water requirements, and to create the AgroClimate irrigation tool (http://mz.agroclimate.org/) to assist farmers in improving irrigation management. This study was based on daily grid-based climate information from 1983 to 2016 from the Climate Forecast System Reanalysis. Daily crop evapotranspiration was calculated by Hargreaves equation and crop coefficients. This tool is available online and considers different planting dates, ENSO phases, and crop growing season lengths. Irrigation needs varied from less than 250 mm per growing cycle during winter to 550 mm during spring. Both El Niño and La Niña influenced the irrigation scheduling, especially from November to March. El Niño periods were related to increased water demand due to drier and warmer conditions, while the opposite was observed for La Niña. The ENSO information might be used to understand climate variability and improve tomato irrigation scheduling in Mozambique.

“…The climate in the region is tropical humid, with two seasons throughout the year; the summer-hot and rainy season, which varies from November to April, and the winter-dry and cold period, which varies from May to September [36]. Over the coast, the equatorial current flows from the north, and it follows towards the south forming cyclonic and anticyclonic vortices [36,37]. The tides are semi-diurnal with a diurnal inequality and the amplitude pattern does not exceed 4 m [37].…”

Monthly length-frequency data, from 2009 to 2014, was used to estimate the growth parameters, mortality, and spawning season, and to assess the exploitation status of Thryssa vitrirostris (Engraulidae) fisheries in Pebane. The von Bertalanffy asymptotic length (L∞) and growth rate (K) were 25.1 cm (standard length) and 0.41 per year (standard length), respectively. Two proxy recruitment peaks were found: the first peak of recruitment occurs from April to July, and the second recruitment peak from September to October. The total estimated mortality rates (Z), natural mortality (M), and fishing mortality (F) were Z = 1.31, M = 0.92, and F = 0.39. For the beach seine gear, the size at first catch of T. vitrirostris was Lc25 = 4.43 cm. The 50% retention size of the catch was Lc50 = 5.39 cm. The retention probability analyses revealed a large rate of juvenile fishing mortality (54.2%). The estimated exploitation rate (0.30) was below the maximum exploitation rate (0.48), and above the optimal sustainable exploitation rate (E50 = 0.28), evidencing a sustainable fishery. However, under such an exploitation regime, it is advised that a continuously monitoring-survey of T. vitrirostris is maintained. An increase in migration of fishermen has been recently recorded in Pebane, due to its rich fisheries, which can increase the fishing effort and the risk of overexploitation if management measures (such as mesh size increase) are not taken in advance.

“…Tal como descrito em Zacarias (2013), a praia do Tofo (no seu sentido mais restrito) constitui um segmento costeiro enquadrado na faixa costeira a oeste da cidade de Inhambane. Tem características rurais, natural e dominada por ondas com uma amplitude média de maré inferior a 3 metros (Hoguane, 2007), protegida por maciços recifes de coral existentes a alguns metros onshore. É uma praia semi-encaixada, uma vez que se encontra abrigada por um promontório apresentando uma forma assimétrica, sendo constituída por uma zona de sombra próxima do promontório, protegida da ação direta das ondas e fortemente curvada, e a outra extremidade relativamente retilínea.…”
