Le projet de Renforcement et d’Extension des Réseaux Electriques de Transport et de Distribution (PRERETD) dans le département de Ngo Ketunjia contribue à la mise en œuvre d’un programme d’accroissement de l’offre énergétique en zone rurale sur tout le territoire national. Les travaux à effectuer consistent en la construction, le renforcement et l’extension des lignes de distribution Moyenne et Basse tensions MT/BT d’une puissance de 30 kV dans des corridors de 16 m de largeur, suivant les tracés des routes existantes. Toutes ces activités auront des impacts sur l’environnement. L’objectif de cette étude est de déterminer les impacts directs ou indirects de la mise en œuvre du projet sur l’équilibre écologique, économique et social de la zone d’influence, d’optimiser sa réalisation conformément aux normes environnementales et de dresser une liste des indicateurs clés à suivre pour la durabilité du projet. Pour ce faire, nous avons procédé par des enquêtes de terrain à l’aide des fiches et questionnaires permettant d’identifier et d’évaluer les impacts de l’électrification sur les différentes composantes de l’environnement (eau, sol, air, faune et flore). L’analyse des impacts socio-économiques et environnementaux nous a permis de proposer, de prioriser, et même de planifier des actions concrètes nécessaires au renforcement des impacts positifs d’une part, et d’autre part, d’atténuer les impacts négatifs. À ce titre, deux principaux impacts positifs potentiels majeurs : développement des activités économiques, et amélioration du cadre et des conditions de vie des populations, ont été identifiés. Deux impacts négatifs moyens : la destruction des cultures et des champs et, la modification du paysage, ont également été identifiés et analysés. Pour parer à cela, les mesures d’atténuation proposées pour ces impacts consistent entre autres à indemniser les personnes affectées, à respecter l’emprise de la ligne et limiter la superficie des parcs à câbles et poteaux ; et éviter d’abattre les espèces protégées. La prise en compte des mesures environnementales et surtout sociales a débouché sur l’élaboration d’un plan de gestion environnementale et sociale pour la préservation et la conservation de l’environnement.

The agricultural community is face with the challenge of increasing food production by more than 70% to meet demand from the global population increase by the mid-21st century. Sustainable food production involves the sustained availability of resources, such as water and energy, to agriculture. The key challenges to sustainable food production are population increase, increasing demands for food, climate change, climate variability, and decreasing per capita land and water resources. To discuss more details on (a) the challenges for sustainable food production and (b) mitigation options available, a Special Issue on “Water Management for Sustainable Food Production” was assembled. This Special Issue focused on issues such as irrigation using brackish water, virtual water trade, allocation of water resources, consequences of excess precipitation on crop yields, strategies to increase water productivity, rainwater harvesting, irrigation water management, deficit irrigation, fertilization, environmental and socio-economic impacts, and irrigation water quality. The articles in the Special Issue cover several water-related issues across the U.S., Asia, Middle East, Africa, and Pakistan concerning sustainable food production. The articles in this Special Issue highlight the substantial impacts on agricultural production, water availability, and water quality in the face of increasing demands for food and energy.
