Case study analysis of innovative producers toward sustainable integrated crop-livestock systems: trajectory, achievements and thought process

This study explores the perceptions of Integrated Crop-Livestock Systems (ICLS) producers. Despite challenges, these producers have perceived benefits in their farming systems and livelihoods from managing ICLS. The research underscores the need for systemic initiatives and knowledge exchange to facilitate the complex management of ICLS. This study can inspire and encourage producers to embark on the ICLS journey.

Fertilization strategies for integrated crop-livestock systems

Integrated Crop-Livestock Systems are nature-inspired food production systems, seeking sustainable intensification. They count on diversity and nutrient cycling to deliver ecosystem services, although their current fertilization practices follow a conventional per crop basis. Scientists Farias et al. evaluated several systems growing soybean in rotation with pastures for sheep. They showed that adopting a system fertilization strategy and integrating crops with livestock saved on fertilization, thereby decreasing costs and pollution while retrieving autonomy at the farm level.

Tropical forages enhance sustainable intensification of crop-livestock systems in Sub-Saharan Africa

Improved tropical forages include annual/perennial grasses, herbaceous/dual-purpose legumes, and multipurpose trees/shrubs. They have been promoted in Sub-Saharan Africa to address food scarcity limiting smallholder livestock productivity. Scientists Paul et al. reviewed 72 studies, demonstrating tropical forages’ multiple benefits on livestock and food crop productivity, household income, and soil quality.

Satisfaction of dairy farmers after converting to organic farming in France

European farmers are increasingly converting to organic farming. Scientists Bouttes et al. recently monitored 19 dairy farm conversions towards pasture-based grazing systems and reduced land use and herd management intensities, in the French Aveyron area. They showed that all farmers were satisfied eventually, which strongly contrasts with previous studies warning about risks associated with organic farming conversion.

Decisions based on inadequate information compromise the sustainability of livestock producers

Animal stocking rate on natural grasslands is a key factor determining livestock system productivity. In Uruguay, scientists Díaz et al. analyzed how beef cattle producers decide on stocking rates, in particular, those exceeding carrying capacity. They showed that management is affected by system configurations, mainly rigidity, poverty and by economic opportunity. They propose a framework to identify barriers and traps as a first step towards increasing the Uruguayan livestock system sustainability.

Intensifying pasture grazing reduces the diversity of spiders in crop-livestock systems

Spiders provide important ecosystem services and reflect the impacts of land-use intensification. In the Brazilian subtropics, scientists Freiberg et al. found that low grazing intensities increased pasture ground spiders’ abundance and richness in a soybean-livestock farming system. Hence, by adjusting grazing intensity in pastures, farmers can promote and diversify the spider communities.

Levers for facilitating the participation to breeding programs in Africa

The sustainability of genetic improvement programs in developing countries depends on breeders’ participation. Scientists Camara et al. evaluated the motivations of breeders and the factors influencing their participation in the N’Dama cattle-breeding program in Senegal. They found that social, family and institutional relationships are factors as important -as distance or production systems features.

Discrepancies between sheep farm strategy and meat industry demands

Comparing five highly efficient and contrasted sheep farming systems across France and Ireland, scientists Benoit et al. showed that optimization of fodder self-sufficiency strategy led to the best economic and environmental performances, while also reducing feed/food competition. However, these systems do not fully fit with the meat industry demand for a regular lamb-meat supply throughout the year and lamb conformation.

Forage crops for sustainable intensification of livestock production

Sustainably intensifying smallholder farming systems on sandy soils is critical to the development of livelihoods in the Mekong region of Cambodia and Laos. Scientists Philp et al. recently reckoned that forages could intensify livestock production in rainfed lowland rice farming systems. Varieties must be adapted to both flooding and drought. Furthermore, soil acidity, low soil fertility, drought and the continual removal of nutrients in harvested forage must be carefully managed.

Integrating grazing animals with soybean production in southern Brazil

In southern Brazil, pastures with mixed oat/ryegrass during winter are directly planted with soybean in summer. Scientists Peterson et al. found that pastures grazed by beef cattle during winter exhibited drier soil in the following summer. However, soybean productivity was unchanged. Long term crop-livestock integration induces unique synergies which need to be considered to ensure the sustainability of these systems.
