Book (stand-alone)Pulse crops for sustainable farms in Sub-Saharan Africa 2018
Also available in:
Food insecurity in sub-Saharan Africa is a problem affecting 153 million individuals (ca. 25%). This problem could be worsen by the ongoing soil degradation, being cause by the reduction of soil organic matter and insufficient nutrient supply. Over 75% of the agricultural land in Africa could be classified as degraded by 2020. This situation can compromise food production in sub-Saharan Africa, both quantitatively and qualitatively, and the sustainability of existing agricultural production systems. The use of fertilizer could revert this situation; however, Africa has almost no capacity to produce fertilizers (African fertilizers production facilities work mainly in blending fertilizers) and therefore fertilizers are produced elsewhere outside Africa and transported from long distances at great expenses. This situation grants to sub-Saharan Africa farmers only a very limited access to fertilizers, thus increasing the risk of soil degradation. Pulses have a long history in sub-Saharan Africa due to their multiple benefits. Pulses, and legumes in general, can play an important role in agriculture because their ability to biologically fix atmospheric nitrogen and to enhance the biological turnover of phosphorous; thus they could become the cornerstone of sustainable agriculture in Africa. In this sense, there is a body of literature that points to diversification of existing production systems; particularly legumes species, which provides critical environmental services, including soil erosion control and soil nutrient recapitalization. This publication is a review of some of the promising strategies to support pulses cultivation and utilization on smallholder farms in sub-Saharan Africa. The review is part of the legacy of the International Year of Pulses (IYP), which sought to recognize the contribution that pulses make to human well-being and the environment. One challenge faced worldwide is that the diversity of pulses are not captured well in statistics. There is not a clear picture of what is grown and where, and this leads to an under-estimation of their importance for sub-Saharan Africa and consequently reduce research investment in pulses. Existing agricultural production systems are dominated by cereals, and represent opportunities for enhanced crop diversification, through promoting local and novel pulse varieties. Mixed-maize is a system that is rapidly growing and poses one such opportunity, particularly for beans. This is due in part to the large number of bean varieties that have been developed to meet local and regional market requirements, through decades long partnerships foster by Pan-Africa Bean Research Alliance (PABRA). Bean research has included pioneering participatory plant breeding, extension linked to participatory community organizations and value chains, as well as attention to informal seed systems. This example shows how pulse research can make a different on smallholder farms in sub-Saharan Africa, by broadening the range of genetic options and supporting innovation. There are many such farmerx approved varieties available that deserve greater promotion, as do technologies such as doubled up legume system innovation recently released by the Malawi government. At the same time, this review has highlighted that variety release has lagged for some pulse crops, and that there is urgent need for more research on adoption, barriers to adoption, and on impact of adoption. Research priorities suggested include greater recognition and attention to expanding properties associated with multipurpose types of pulses, which are popular in sub-Saharan Africa. Different types of pulses are needed for different functions and in general, multipurpose pulses are the best to respond to the diverse needs of farmers, including food, fuel and fodder, and ecosystem services such as pollination. There is a trade-off between the harvest index and other functions, which have too often been overlooked by researchers and decision makers who tend to focus almost exclusively on increasing grain yields. Pest tolerance, as well as extension of educational approaches and agronomic advice to strengthen integrated pest management (IPM) is another area urgently needing attention. Finally, the role of specific legumes and associated biochemical properties in promoting ecosystem health, community health – this is a crucial area for research that will provide urgently needed options for women farmers – and for sustainability of communities. -
MeetingClimate variability, adaptation strategies and food security in Malawi 2014
Also available in:
No results found.This paper assesses farmers’ incentives and conditioning factors that hinder or promote adaptation strategies and evaluates its impact on crop productivity by utilizing household level data collected in 2011 from nationally representative sample households in Malawi. We distinguish between (i) exposure to climatic disruptions, (ii) bio-physical sensitivity to such disruptions, (iii) household adaptive capacity in terms of farmers’ ability to prepare and adjust to the resulting stress, and, fina lly, (iv) system-level adaptive capacity that serve as enabling factors for household-level adaptation. We employ a multivariate probit (MVP) and instrumental variable technique to model farming practice selection decisions and their yield impact estimates. We find that exposure to delayed onset of rainfall and greater climate variability as represented by the coefficient of variation of rainfall and temperature is positively associated with the choice of risk-reducing agricultural practices suc h as tree planting, legume intercropping, and soil and water conservation (SWC); however, it reduces the use of inputs (such as inorganic fertilizer) whose risk reduction benefits are uncertain. Biophysical sensitivity of plots increases the likelihood of choice of tree planting and SWC. In terms of household adaptive capacity, we find that wealthier households are more likely to adopt both modern and sustainable land management (SLM) inputs; and are more likely to adopt SLM inputs on plots unde r more secure tenure. In terms of system-level adaptive capacity, results show the key role of rural institutions, social capital and supply-side constraints in governing selection decisions for all practices considered, but particularly for tree planting and both organic and inorganic fertilizer. Finally for productivity, we find that on average use of both modern and SLM practices have positive and statistically significant impact on productivity of maize. For SLM practices that also respond t o exposure and sensitivity, these results provide direct evidence of their potential to aide households in adapting to further climate change. Results presented have implications for understanding and overcoming barriers to selection for each practice, distinguishing structural aspects such as exposure and sensitivity from potential interventions at the household or systemic levels linked to adaptive capacity. -
Book (series)Negotiated territorial development in a multi-stakeholders participatory Resource Planning approach: an initial sustainable framework for the Near east Region 2016
Also available in:
No results found.Throughout the Near East, land and water shortages, land degradation, out of date land tenure systems and food insecurity are compounded by asymmetries in gender roles and power, by severe imbalances in the political-military structures within and between countries, by flagrant deficiencies in land and water management and control systems, and by the incessant increases in demand driven by high rates of population growth and urbanization. This interplay of forces and dynamics form a complex hydr o socio-political web that governs the allocation land and water and who benefits from their availability and their ultimate sustainability. The current allocation arrangements of the region's three major river basins - the Nile, the Euphrates-Tigris and the Jordan - are nascent sources of tension, and potential sources of conflict and violence. Political instability that characterizes the Near East continues to intensify scarcity, suppresses growth and engenders poverty and is being increasingl y exacerbated by the impending consequences of climate change. The Middle East is one of the most water poor and water stressed regions of the globe. While the region is home to 5.1% of the people of the world, it has about only 1% of the world renewable fresh water. Today's annual per capita availability of fresh water in the region is only one seventh of its 1960 level, falling from 3,300 cubic metres per person in 1960 to less than 500 cubic metres in 2015. This is the lowest per capita wat er availability in the world. The current land tenure systems are failing to address long-standing problems that include smallholder farmers, landless households and most marginalized groups such as women continue to compete for shrinking natural recourses, while pastoralists are losing control of their traditional grazing areas. Use, management and access to land and water are becoming extremely sensitive matters as the number of users grows. Governments and local actors have often perceived these major issues differently. This requires effort to be made to ensure a participatory approach to decision-making that effectively involves all the local actors concerned in an equitable and balanced manner. About 90% of the land area in this Region is subject to land degradation in different forms and over 45% of land suitable to farming is exposed to various types of land degradation which include soil nutrient depletion, salinity and wind and water erosion. Per capita arable land availa bility in the region is among the lowest in the world where many countries in the region show levels that are exceptionally low (on average less than 0.123 hectares per person) and the range varies between 0.01 hectares per person (Oman, Qatar, Palestine, Kuwait and Bahrain) to 0.34 hectares in the Sudan in 2015. Arable land as a percentage of land area in the region is very low ranging between 0.1% in Oman to 18.4% in Tunisia in 2013. Most of the countries in the region show shares below 10%. O nly Morocco, Tunisia, and Iraq sow percentages above 10%. Irrigated land areas in the region also represent a small share of total arable land areas. In many of the countries in the region these shares are way below the world average. Only Iran (17.4%) and the UAE (12.5%) show high relative shares in the period 2011-2015. The Region’s critical shortage of water and cultivable land, including the increasing pressure on these resources and their degradation makes their efficient management a pa ramount task. It will be necessary in this regard to promote the engagement of all concerned stakeholders in planning and managing land, water and agrobiodiversity. Actual physical scarcity of land and water, even in the Middle East region, is not the only key issue. Conditions of economic scarcity seem to be equally pressing; there is perhaps enough land and water to meet society's need, but there are few incentives for wise, efficient and egalitarian use of these critical resources. Climate change will impinge on this region’s fragile water balances, suitable land for cultivation, grazing land and food production capacities and will exacerbate the problems and issues of food security. Measures, policies, strategies and institutional capacities to mitigate the impending catastrophic consequences of climate change and to improve the societies’ resilience and adaptation to its consequences are needed now. The sooner the regulatory and institutional setups are put in place the easier the task to deal with climate and other risks. It is necessary and vital to rise up to this challenge by enlisting the stakeholders in the initiatives to promote sustainability and efficiency of land and water use and the management of food security issues. An active engagement of concerned stakeholders in planning and managing water, land and agrobiodiversity necessitates first and foremost the engagement of and participation of particularly women and girls and marginalized groups in all wate r and food aspects as they constitute the main agricultural labour force and the most deprived segments of society. Gender and the water and land nexus in the Arab region is an area where there is still relative little information. There is little systematic knowledge about the many means by which women and men manage water and land in the region. Evidence shows that while women in Egypt have a significant role to play in water use in the process of food production by controlling and managi ng water flows in the fields and supervising workers during irrigation, they rarely own the land they cultivate. Rural women in Yemen spend huge amounts of time collecting and transporting water, often up and down steep slopes and coordinate water allocation and distribution for the various needs of the family and the household but they are rarely involved in decision making and management councils that govern land and water uses. Women everywhere in the Middle East evaluate water quantity and q uality and prioritize water for drinking and health and sanitation purposes but they rarely share equally in the benefits of their labor or in the ownership of the land and water resources. This is why an integrated water and land management system anchored on a genuine participation of stakeholders will be crucial in determining whether the Arab world achieves the Sustainable Development Goals (SDGs) and aspirations for reducing poverty and enhancing shared prosperity. Water and land are the c ommon currency which links nearly every SDG, and it will be a critical determinant of success. Abundant water supplies and cultivable land are vital for the production of food and will be essential to attaining SDG 2 on food security; clean and safe drinking water and sanitation systems are necessary for health as called for in SDGs 3 and 6; and water is needed for powering industries and creating the new jobs identified in SDGs 7 and 8. None of this is achievable without adequate and safe water and sufficient suitable land to nourish the planet’s life-sustaining ecosystem services identified in SDGs 13, 14 and 15.
