Internships

The ARChE_Net network supervises French and foreign students for internships leading to a MSc qualification on the following topics:

  • Characterization of resources (soil, forage, organic matter), sampling protocols and spectra collected via NIRS
  • Characterization of fodder by satellite imagery (NDVI)
  • LASER2 – database for herd management at animal level of tropical livestock production systems
  • Development of value-adding tools (videos, e-learning, etc.)

Observatory of grass growth

Being a student of BTSA PA (livestock production), I’m carrying out my 2-year apprenticeship within the Eclipse project. My internship is focused on the observatory of grass growth, in collaboration with the Reunion Association of Pastoralism (ARP). The main objective is to allow farmers to have better management of their grasslands thanks to the collection of grass growth data and respective analysis.

The partnership between CIRAD and ARP (Reunion Association of Pastoralism) has allowed the creation of the first observatory of grass growth at Reunion Island.The internship makes part of this project. It aims to collect a lot of data in order to organize and calibrate the different tools used to evaluate Reunion’s fodders and grasslands.It also aims to create information sheets for farmers which are aimed at helping them to have the most accurate information on their pastures, to better improve them and to better manage their fodder.

This internship is part of action 6 of the ECLIPSE project which consists in enhancing and communicating. The objective is therefore to enhance the results of the project, to present the work done mainly on Reunion Island but also to support communication in the partner countries. The definition of the channels and of the communication tools represented the major part of my internship, besides the realization of two videos that also paced the six months that I spent on Reunion Island. Supervised by the ECLIPSE project coordinator and communication officer, this internship requires autonomy and strength of proposal in order to face the collaborators and to carry out communication.

Impact of tropical climate on cattle performance in Reunion Island

Reunion Island has a great diversity of climates, due to the topography of the island. Farmers are confronted with very diverse climates ranging from humid tropical to semi-arid, through high altitude areas. Ruminants are known to be sensitive to climatic conditions, especially in tropical areas. The aim of my internship is to study the relationship between climate and beef cattle performance in Reunion Island. For that, on the one hand I carry out a statistical analysis between farm performance indicators and climatic indicators. And on the other hand, I perform measurements of heat stress indicators on animals using intra-ruminal boluses.

This internship is part of Yvane Marblé's thesis, "Agricultural pathways and contribution of dairy systems to the sustainability of territories", more particularly in Reunion Island. Based on the agrarian diagnosis previously carried out, this internship aims to evaluate the current and multiple contribution of dairy farming to the sustainability of Reunion Island's territory based on the measurement and calculation of multi-criteria sustainability indicators (environmental, technical, socio-economic and socio-territorial), at farm and territory level.

Creation of an Observatory of grass growth

In collaboration with the Association Réunionnaise de Pastoralisme (ARP), an Observatory of grass growth will be created. The main goal is to elaborate a weekly newsletter with information about grass growth. This bulletin will allow Reunionese farmers to monitor their fodder as close to reality as possible. Therefore, the internship consists of studying the feasibility, the assembly and the design of the Observatory.

The improvement of food quality, production and its regularity are interesting levers to overcome the low forage availability during the dry season. The incorporation of more diversity into Réunion's forage systems seems to be appropriate. This internship proposes to study the poaceae / fabacea association in terms of fodder production via the establishment of an experimental plot and its monitoring. The study will allow the obtention of yields, feed values, composition and weed control by testing three different legumes (alfalfa, desmodium and stylosanthes) and three grasses (panicum, brachiaria and chloris) in association and in monoculture as a control.

Feed resources in cattle feeding systems of Anjouan in the dry season.

The objective of the internship is to characterize the feed value and the use of forage resources during the dry season in Anjouan (Comoros). For this study, I set up the monitoring of nine farmers to identify the plant species used and the quantities taken in tethering feeding systems. On the other hand, the conduction of surveys allows me to identify farmers’ adaptation strategies to face forage deficit during the dry season. Sampling will allow to set up a calibration equation of the NIRS tool (Near-Infrared Spectroscopy) adapted to the resources of Anjouan. This model will make it possible to predict the feed value of local fodder and to make proposals in order to improve the diets distributed by farmers.

Determination of fodder strategies for suckler cattle on Reunion island

Stagnation of yields and forage deficits are increasingly recurring on Reunion Island. Therefore, it was decided to carry out a study to determine forage strategies for suckling cattle. within the framework of the ECLIPSE project and the RITA Animal programme. It is within this context that my internship will be carried out. During this period, cattle breeders on the island will be questioned about their practices in order to better understand forage strategies and to identify the possible brakes and levers of production. This identification will be supported by statistical analysis of the interviews.

Environmental assessment of diversified livestock systems in India

The Indian dairy sector faces two challenges in particular:

- employment and securing the livelihoods of 70 million dairy farmers;
- environment, within the context of global warming and the strong competition for land use.

Therefore, the objective of this sector is, on the one hand, to increase its overall production and, on the other hand, to reduce its environmental impact. My internship is carried out within this context and within the framework of the IndiaMilk project, more specifically on the environmental aspect.
My mission is to carry out an environmental assessment of the fossil energy consumed and of all the greenhouse gases emitted. It is based on data and results from 7 agrarian diagnoses carried out between 2014 and 2016 by other students.
The data collected and the resulting analysis will allow the co-design of solutions for the dairy sector in India.
