This paper examines the reform of water and irrigation management in Africa and compares it with similar reforms in Asia.  Several things are evident from the review.  First, Sub-Saharan Africa (SSA) is at an earlier stage of irrigation development and reform than Asia.  Second, the articulated need for reform is much stronger in Asia than it is in SSA.  Third, the productivity of small-scale irrigated farms is significantly lower in SSA compared to Asia.  Thus any irrigation investment strategy in SSA should be different from Asia and focus on increasing small-farm productivity as well as small-scale irrigation projects.  Finally, all direct government irrigation investments should be done jointly with decisions regarding the type of project management.

Smallholder or informal or small scale irrigation is one of the three broad categories into which irrigation is put in Ghana. Faced with climate change and variability resulting in extreme events, irrigation serves as insurance against crop failure and permits all-year-round production. The study was carried out to underscore the challenges and prospects of small scale irrigation in the face of climate variability in Ghana and to propose the way forward. The key source of data for this study was secondary data which were collected mainly by reviewing published reports, policy documents, articles, online sources and official web sites of relevant state and international institutions. A number of challenges confront small scale irrigation development including high cost of energy, encroachment on irrigation lands, illegal mining activities and lack of technological know-how among others. Small scale irrigation has a promising future owing to renewed collaborative spirit GIDA has with major stakeholders. To forestall encroachment on irrigation lands, we recommend amendment of Irrigation Development Authority Act to empower GIDA to exercise absolute control over irrigation lands. It is also recommended that the Authority collaborates with relevant stakeholders to develop effective programmes for building capacity of contractors involved in development of irrigation infrastructure. To overcome the challenge of high cost of energy, it is recommended that government makes long-term investment into conversion of electric and diesel/petrol powered irrigation pumps to solar powered ones.

<p>Irrigation facilities is one of the key factors in farming, especially for food crop farming, including rice. A small-scale irrigation system has an area of less than 500 hectares, and it is the backbone of family food security which in turn will lead to national food security. Damage irrigation system networks will threaten food production increase. In the future, irrigation infrastructure must be better managed so that agricultural sector can realize agricultural diversification, conserve wider irrigation system and maintain local wisdom and social capital in irrigation management. The objective of the paper is to analyze performance, problems and solutions of small irrigation systems in Indonesia, including small irrigation concepts and understanding, small irrigation performance and development, small irrigation development policies, factors affecting smallscale irrigation development, investments, and prospects. The paper also compares various performances, problems and solutions of small irrigation systems in other countries. Small scale irrigation performance is often better than large-scale irrigation, in the sense of water availability throughout the year and equitable water distribution for all service areas.</p><p> </p><p>Abstrak</p><p>Sarana irigasi merupakan faktor penting dalam usaha tani khususnya tanaman pangan. Sistem irigasi kecil dengan luas oncoran kurang dari 500 ha merupakan tulang punggung ketahanan pangan keluarga yang pada gilirannya bermuara pada ketahanan pangan tingkat nasional. Kerusakan jaringan sistem irigasi akan mengancam peningkatan produksi pangan. Di masa yang akan datang, infrastruktur irigasi harus dikelola secara lebih baik agar sektor pertanian dapat mewujudkan diversifikasi pertanian, semakin luasnya konservasi sistem irigasi, serta kearifan lokal dan modal sosial dalam pengelolaan irigasi dapat terpelihara. Tulisan ini bertujuan menganalisis kinerja, masalah dan solusi sistem irigasi kecil di Indonesia, termasuk konsep dan pengertian irigasi kecil, kinerja dan perkembangan irigasi kecil, kebijakan pengembangan irigasi kecil, faktor-faktor yang mempengaruhi pengembangan investasi irigasi kecil, dan prospek pengembangan irigasi kecil. Dalam tulisan ini juga dibandingkan berbagai kinerja, masalah dan solusi dari sistem irigasi kecil di negera-negara lain. Kinerja irigasi kecil seringkali lebih baik dari irigasi skala besar, dalam arti ketersediaan air sepanjang tahun dan terdapat keadilan pembagian air untuk seluruh wilayah oncorannya.</p>
