Sustainable development of smallholder crop-livestock farming in developing countries

Meeting the growing demand for animal-sourced food, prompted by population growth and increases in average per-capita income in low-income countries, is a major challenge. Yet, it also presents significant potential for agricultural growth, economic development, and reduction of poverty in rural areas. The main constraints to livestock producers taking advantage of growing markets include; lack of forage and feed gaps, communal land tenure, limited access to land and water resources, weak institutions, poor infrastructure and environmental degradation. To improve rural livelihood and food security in smallholder crop-livestock farming systems, concurrent work is required to address issues regarding efficiency of production, risk within systems and development of whole value chain systems. This paper provides a review of several forage basedstudies in tropical and non-tropical dry areas of the developing countries. A central tenet of this paper is that forages have an essential role in agricultural productivity, environmental sustainability and livestock nutrition in smallholder mixed farming systems

Improving Forage Production Quantity and Quality Using Native Legume Species in Semi-Arid Agrosilvopastoral System

Agrosilvopastoral systems provide a range of livelihood services, either directly through forage production or indirectly by the beneficial effects on soil conservation, nutrient cycling, pollutant filtering, and biodiversity enhancement. Hence, improved silvopastoral systems have ample scope to rehabilitate degraded pastures to sustain livestock production, which remains a strong pillar for the livelihoods of the agrosilvopastoral communities. To evaluate the impact of Hedysarum coronarium L. (sulla) reseeding on pasture productivity, plant cover and plant density in semi-arid silvopastoral systems, an experiment was carried out in Sbaihia Site, Zaghouan Governorate, Tunisia during 2018-2019 growing season. The experiment was laid out under a randomized complete block design having 3 treatments including reseeding sulla; protection from grazing and control (free grazing) with three replications per treatment. Preliminary results showed that there were significant differences (p\u3c 0.05) among the three treatments. Reseeded sulla and protected plots recorded 100% plant cover while the control plots had less than 60%. The estimated biomass for the reseeded plots was four times higher than the biomass production in the protected plots and eleven times higher than the control plots. The highest plant density was recorded in the reseeded plots (163.2 plants/m2), followed by the protected plots (30.6 plants/m2) while the lowest value was recorded in the control plots (29.8 plants/m2). Based on these findings, it is concluded that reseeding well-adapted native forage species has a great potential to improve productivity of semi-arid silvopastoral systems, which would contribute towards reducing the feeding cost and, therefore, enhancing the income of the agrosilvopastoral communities

Rangelands and Pastoralism of the Middle-East and North Africa, from Reality to Dream

The Middle East and North Africa (MENA) is a vast area covering 20 countries from western Asia to North Africa, with nearly 9,000,000 Km2 and 303 million hectares of total rangelands. Rangelands play an essential role in supporting people\u27s livelihoods and food security. Mobile pastoralism is the most viable and resilient form of production and land use in the fragile drylands of MENA. The region\u27s governments have considered mobile pastoralism as backwards mainly because it was difficult to deliver mobile services to them. They designed various policies that were not in harmony with pastoralists\u27 customary rules and norms and severely weakened their mutual aid associations and governance systems for natural resources management. Nowadays, pastoralists\u27 rangelands and customary territories are shrinking, fragmenting, and degrading due to various reasons, but mainly the expansion of agricultural or industrial needs. Based on pastoralists and rangelands\u27 socio-ecological values, the world needs to apply the evidence-based experiences and Indigenous knowledge of pastoralists in preventing rangeland degradation. It is urgent to start a new era for a paradigm-shift for an inclusive interaction, establishing pro-poor livestock policies. These polices would address the barriers and bottlenecks faced by pastoral and agro-pastoral communities, and secure land tenure at community and landscape levels through multi-stakeholder dialogue, including during the International Year of Rangelands and Pastoralists (IYRP). It is time to call for respect of customary governance systems of pastoralists, recognition of their territories as Indigenous and Community Conserved Areas (ICCA1s—territories of life) under various and norms in the region like Qoroq, Hima, Agdal, and any other form of local conservation to prevent fragmentation of pastoralists territories and rangelands degradation leading to desertification

Seasonal preference of Awassi sheep for Atriplex shrubs suitable for Mediterranean rangelands

The relative preference of Awassi sheep for four promising Atriplex species, A. halimus, A. nummularia, A. canescens and A. lentiformis was tested in cafeteria trials. Atriplex species were offered to sixteen sheep in cafeteria-type experiments during two seasons, spring and autumn. After an adaptation period of 7 days, sheep were offered the species over eight consecutive days. The species were placed in troughs for two hours in the morning after overnight fasting. Sheep were housed individually in pens adjacent to each other. In both seasons, whole species and their botanical fractions were evaluated for chemical composition and in vitro digestibility. The variability of nutritive value among species was not dependent on season or botanical fraction. Time series analysis showed that intake levels and ranking of species did not change over the eight days. Average daily proportions (%) of whole shrub eaten were A. halimus (70.9) A. nummularia (70), A. lentiformis (65.3), and A. canescens (57.9). In autumn, the same order of consumption was maintained, though intake levels tended to be lower compared to spring. The behavioral pattern revealed that the number of return visits to troughs and time spent feeding on species did not influence intake levels. The botanical structure of species explained 20% of the variation in proportion of intake of whole species. The proportion of leaf was the major contributor to variation in proportion of intake of whole species. Relative preference of whole species was explained by intake, nutritive value and fractional proportions of the botanical fractions
