Soomaaliya iyo Geeska Afrika waxay heli karaan 300–800 mm roob sannadkii — laakiin biyahaas inteeda badan way lumiyaan sababtoo ah ma jiraan habab lagu kaydiyo. Kaydinta biyaha roobka waxay beeralayda siisaa biyo bilaash ah xilliga abaaraha. Somalia and the Horn of Africa receive 300–800 mm of rainfall per year — yet most of it runs off because there's no infrastructure to capture it. Rainwater harvesting gives farmers free water during dry spells. تتلقى الصومال والقرن الإفريقي 300–800 ملم أمطار سنوياً — ومعظمها يضيع. تجميع مياه الأمطار يوفر للمزارعين ماءً مجانياً للجفاف. Somalia na Pembe ya Afrika hupata mm 300–800 za mvua kwa mwaka — lakini nyingi hupotea.
Habab Caanka AhCommon Methodsالطرق الشائعةMbinu
1) Saqafka guriga / xerada xoolaha1) Rooftop catchment1) تجميع من الأسطح1) Kupokea kutoka paani
Saqaf saxan ah oo 100 mitir-laba-jibaaran (m²) wuxuu ka soo kaydsadaa 1,000 litir roob 10 mm kasta. Ku xidh gutter-ka cidhifka saqafka oo biyaha ku jiidi haan biyo (tank) plastic ah ama qaboojiye (cistern). Iska ilaali rooga ugu horeysa (first-flush diverter) oo wasakhda saaray. A 100 m² flat roof captures about 1,000 litres for every 10 mm of rainfall. Fit gutters along the eaves, pipe water to a plastic tank or cistern, and use a first-flush diverter to discard dirty water from the start of the rain. سطح 100 م² يجمع 1,000 لتر لكل 10 ملم مطر. ركّب المزاريب وحوّل المياه إلى خزان، مع جهاز يطرح أول جريان قذر. Paa la 100 m² hukusanya lita 1,000 kwa kila mm 10 za mvua.
2) Berkad dhulka qodan (water pan)2) Earth pan / pond2) برك مياه أرضية2) Bwawa la ardhini
God dhulka ah oo 500–5,000 m³ leh oo lagu daboolay plastic-ga (HDPE liner) si biyaha aysan u liqi karin ciidda. Daboolayaasha ama geedaha agteeda waxay yaraysaa uumiga. Mid yar (500 m³) ayaa waraabin karta 0.5 hektar khudaarta dhowr bilood. An excavated pit 500–5,000 m³ lined with HDPE plastic to stop seepage. Shade or trees nearby reduce evaporation. A small 500 m³ pan can irrigate 0.5 ha of vegetables for several months. حفرة 500–5,000 م³ مبطنة بـHDPE. الظل يقلل التبخر. 500 م³ تروي 0.5 هكتار من الخضروات أشهراً. Shimo la 500–5,000 m³ na HDPE. Bwawa la 500 m³ humwagilia 0.5 hektari ya mboga miezi kadhaa.
3) Zai pits3) Zai pits3) حفر زاي3) Mashimo ya Zai
Godad yaryar (20×20×20 cm) oo lagu qodo dhulka qalalan; ku dar digo + samadka. Beero hal dhir godkii (galley, masaggada). Zai-yada waxay ururiyaan biyaha runoff-ka oo kor u qaadaan wax-soosaarka 50–100% dhulalka qalalan. Small pits (20×20×20 cm) dug into dry land and filled with manure and compost. Plant one crop per pit (maize, sorghum). Zai pits trap runoff and can lift yields by 50–100% on degraded land. حفر 20×20×20 سم تُملأ بالسماد وتُزرع بنبتة واحدة. ترفع الإنتاج 50–100%. Mashimo madogo 20×20×20 sm yenye samadi. Huongeza mavuno 50–100%.
4) Mataambooyinka (terraces) iyo half-moon bunds4) Terraces and half-moon bunds4) المصاطب والأهلة4) Matuta na nusu-mwezi
Dhulka jiifka ah, dhis matamboo ama bund (lay'b shaqal ah oo dheer 30 cm) si biyaha runoff-ka u joojiyaan oo ay u nuugaan ciidda. Tani waxay yarayn kartaa nabaad-guurka 60–80% oo waxay kaydsataa biyaha geedaha agtooda. On sloping land, build terraces or half-moon bunds (30 cm earth ridges) to slow runoff and force infiltration. This reduces erosion by 60–80% and stores water for nearby trees and crops. على المنحدرات، ابنِ مصاطب أو سدود نصف قمر لإبطاء الجريان. يقلل التعرية 60–80%. Kwenye mteremko, jenga matuta. Hupunguza mmomonyoko 60–80%.
Xisaabinta AwoodaCalculating Capacityحساب السعةKuhesabu Uwezo
Caanka ah: Biyo (litir) = Aagga (m²) × Roobka (mm) × 0.8. Tusaale: saqaf 80 m² oo helay 50 mm roob = 80 × 50 × 0.8 = 3,200 litir. Sannad kasta, beerta 1 hektar waxay haysataa 4 milyan litir biyo roob (400 mm) — laakiin oo aan la kaydsan, way lumayaan. Formula: Water (litres) = Area (m²) × Rainfall (mm) × 0.8. Example: an 80 m² roof in a 50 mm storm = 80 × 50 × 0.8 = 3,200 litres. Each year, a single hectare receives 4 million litres of rain (at 400 mm) — most of it lost without storage. الماء (لتر) = المساحة (م²) × الأمطار (ملم) × 0.8. مثال: سطح 80 م² ومطر 50 ملم = 3,200 لتر. Maji (lita) = Eneo (m²) × Mvua (mm) × 0.8.

Kaydinta biyaha roobka waxay yarayn nabaad-guurka ciidda, kor u qaadda dhulka biyaha ku jira (groundwater recharge), oo yarayn fatahaadaha. Beerta hal hektar oo leh terraces iyo zai pits waxay ka soo nuugtaa 30–50% biyo roob oo dheeraad ah marka loo eego dhul aan la habayn. Rainwater harvesting reduces soil erosion, recharges groundwater, and limits flash floods. A 1 ha plot with terraces and zai pits absorbs 30–50% more rainfall than untreated land. تقلل التعرية وتغذي المياه الجوفية وتحد من الفيضانات. Hupunguza mmomonyoko, hujaza maji ya chini.
