“…Among the often-studied adaptation options are on-farm practices and biophysical measures that include increased soil organic matter, improved cropland management, use of local genetic diversity, improved livestock management, crop-livestock mixed system, multiple cropping, improved grazing land management, increased food productivity, prevention and reversal of soil erosion, agroecological approaches, and so on (Altieri and Koohafkan 2008). However, Nie et al (2016) argued that while integrated crop-livestock systems present some opportunities for climate change adaptation and environmental benefits, there are some challenges, including yield reduction, difficulty in pasture cropping, grazing, and groundcover maintenance in high-rainfall zones, and development of persistent weeds and pests. Major adaptation options in agricultural sectors in SA are summarized in the following subsections.…”

Agriculture in South Asia is vulnerable to climate change. Therefore, adaptation measures are required to sustain agricultural productivity, to reduce vulnerability, and to enhance the resilience of the agricultural system to climate change. There are many adaptation practices in the production systems that have been proposed and tested for minimizing the effects of climate change. Some socioeconomic and political setup contributes to adaptation, while others may inhibit it. This paper presents a systematic review of the impacts of climate change on crop production and also the major options in the agricultural sector that are available for adaptation to climate change. One of the key conclusions is that agricultural practices that help climate change adaptation in agriculture are available, while the institutional setup to implement and disseminate those technical solutions is yet to be strengthened. Thus, it is important to examine how to bring the required institutional change, generate fund to invest on these changes, and design dynamic policies for long-term climate change adaptation in agriculture rather than a mere focus on agricultural technology. This is one of the areas where South Asian climate policies require reconsidering to avoid possible maladaptation in the long run.

“…Grazing pasture and croplands occupy a significant portion of land surface in the world. In the last decades, many countries, such as Australia [1,2], France [3], United States of America [4,5], and Brazil [6][7][8], have adopted the integration of crop and livestock systems as an alternative for sustainable production intensification. Integrated Crop-Livestock Systems (ICLS) seek the synergism between agricultural and livestock resources in combination with land use and management practices focused on the conservation of natural resources [9].…”

Monitoring Pasture Aboveground Biomass and Canopy Height in an Integrated Crop–Livestock System Using Textural Information from PlanetScope Imagery

et al. 2020

Fast and accurate quantification of the available pasture biomass is essential to support grazing management decisions in intensively managed fields. The increasing temporal and spatial resolutions offered by the new generation of orbital platforms, such as Planet CubeSat satellites, have improved the capability of monitoring pasture biomass using remotely sensed data. Here, we assessed the feasibility of using spectral and textural information derived from PlanetScope imagery for estimating pasture aboveground biomass (AGB) and canopy height (CH) in intensively managed fields and the potential for enhanced accuracy by applying the extreme gradient boosting (XGBoost) algorithm. Our results demonstrated that the texture measures enhanced AGB and CH estimations compared to the performance obtained using only spectral bands or vegetation indices. The best results were found by employing the XGBoost models based only on texture measures. These models achieved moderately high accuracy to predict pasture AGB and CH, explaining 65% and 89% of AGB (root mean square error (RMSE) = 26.52%) and CH (RMSE = 20.94%) variability, respectively. This study demonstrated the potential of using texture measures to improve the prediction accuracy of AGB and CH models based on high spatiotemporal resolution PlanetScope data in intensively managed mixed pastures.

“…Crop-livestock systems have long provided food security and have a continued potential to mitigate the adverse effects of the changing market conditions in northern Laos (Nie et al 2016). Declines in such systems to simply favour intensifying cattle production could increase smallholder vulnerability to a fluctuating market.…”

Impact of forage introduction on cattle grazing practices and crop–livestock systems: a case study in an upland village in northern Laos

2019

Lao smallholders are experiencing livestock grazing land constraints due to resettlement, increasing cattle numbers and commercial cash crop plantations. In this paper we describe changes in cattle grazing systems in an upland village in northern Laos, including the role of forage crops and their effects on cattle productivity. We interviewed 92 Hmong and Khmu households about their migration history, cattle grazing practices, cattle productivity and other livelihood activities. In addition, we measured the heart girths of 231 cattle. We found that the traditional free-range cattle grazing has diverged into three distinct systems incorporating fields fenced to different degrees. Although none of the three systems increased cattle body size, the forage pasture and swidden-farming system successfully increased the grazing capacity compared with other systems. Thus, this method appeared to be the most suitable for Hmong smallholders to manage crop and cattle production in the context of land constraints. Efforts should be made to examine how the newly implemented systems could attenuate villager livelihood and pre-emptively address the problems associated with degrading fallow land.
